Then and Now - Progression in Health Issues

There are lots of changes in my perception of health between the 1960s and today.

Allergies. Hay fever sneezes were a big part of my life during the growing season in Wichita Falls. TX in the 1960s. I remember learning to swallow pills as a young teenager so I could take over-the-counter medication! Now I almost never need to take anything for allergies. Perhaps better air filtration indoors overcomes the pollen and mold I experience outdoors….and maybe the areas I frequent now are not a challenging for people with hay fever tendencies.

Gastro-intestinal bugs. I remember having short duration ‘stomach flu’ in the 1960s. My mother gave us chipped ice, fizzy liquids or apple juice until we could graduate to saltine crackers and slowly back to other food. It never lasted very long. Strangely enough – I don’t remember any recent instances!

Blisters. I remember getting blisters from my shoes as I was growing up. It was probably because my heals were too narrow for most of my shoes…so the shoe tended to move around somewhat independent of the foot and rubbed when it did. I had a pair of sandals in the late 1960s that rubbed a blister on my big toe that was sustained enough (because I continued to wear the shoes) to create a scar. I guess I learned to buy and/or wear my shoes more effectively because I haven’t had a blister in a very long time.

Sunburns. Sunscreen was not available in the 1960s although I do remember thick white zinc oxide that lifeguards at the pool used on their noses. In general, people talked more of building up a tan early in summer to avoid burns later. Now – of course – sunscreen is very big deal for me…and wearing hats and sun-block shirts.

Cuts and scrapes. I had my share of skinned knees and minor cuts growing up…nothing bad enough to require stitches or an extra Tetanus shot. Some of them produced scars that have faded over time. These days I am more likely to get a paper cut than anything else although I am consciously eliminating as many fall hazards around my house as I can. My last scraped knees happened almost 10 years ago when I tripped over a chunk of asphalt at a star observing gathering in Hawaii (in the dark…the chunk of asphalt did not show up at all) and those scars are relatively new and very white. The response is very similar between the 1960s and now: clean the wound (soap and water), stop the bleeding with pressure, antibiotic ointment, bandage if oozing (otherwise give it air).

Foot/leg cramps. My feet have always been prone to cramps. In the 1960s, the cramps were most frequently arch related but sometimes involved the toes as well. In retrospect, they might have been mostly caused by dehydration. The same happens occasionally now but less frequently in my feet/toes more…in my ankles and calves. If I pay attention to my hydration before bedtime…they usually don’t occur!

Exercise. I remember tennis and softball and playgrounds in the 1960s; we walked to elementary school; hiking was one of the activities with Camp Fire Girls. I didn’t consider myself athletic and I still don’t, but I am more conscious of getting a baseline of ‘steps’ every day and sometimes longer walks as well. Mowing the yard and doing other gardening also counts as exercise for me now. In my current stage of life, exercise is one of the pillars to sustain mobility and health.

Coordination. I was growing fast in the 1960s, struggling to improve my coordination enough to dance or swim, play a musical instrument, or perform the tasks of living. Coordination now involves the challenges of intermittent aches in my back and joints…I move differently to keep from hurting! So far, I haven’t curtailed any activities, but I can envision a time…hopefully years in the future…when that could happen.

There is a contrast between growing up years and the being 70ish – but I also realize that it is not as substantial for me as it is for others. I have been fortunate.

What happens when you take too much caffeine - When we consume caffeine, it's quickly absorbed into our bloodstream, where it out-competes adenosine by preventing it from connecting to these receptors and doing its job to make us feel tired. This is why consuming caffeine can make us feel more awake and alert. Caffeine can also boost levels of other neurotransmitters like dopamine and adrenaline, which can make you feel more stimulated. Research has associated caffeine consumption with up to a 60% reduced risk of developing Alzheimer's. One explanation for this is that caffeine improves blood flow to the brain. While caffeine enters the gut quite quickly, its effects can take hours to wear off. Scientists recommend having your last 'dose' of caffeine eight hours and 48 minutes before you go to bed.

Why do 1 in 10 Americans get eczema? Is it too much salt? - Eczema, also known as atopic dermatitis, is a chronic disease that causes dry, itchy skin. It's one of the most common skin conditions, affecting more than 31 million people in the U.S., and one in 10 people will develop it at some point. It has become increasingly common in recent years, especially in industrialized countries, implicating environmental and lifestyle factors like diet.

A fierce battle is being fought in the soil beneath our feet – and the implications for global warming are huge - In some parts of the world, increased CO₂ means tiny bugs in the soil “hold onto” their phosphorus, making less available for trees.

Depressive symptoms may hasten memory decline in older people – 16 years of data from 8,268 adults with an average age of 64. This study shows that the relationship between depression and poor memory cuts both ways, with depressive symptoms preceding memory decline and memory decline linked to subsequent depressive symptoms. So – interventions to reduce depressive symptoms might slow memory decline.

Then and Now – Vaccinations

When I was growing up in the 1960s, there were a lot fewer vaccinations…but I remember my mother was keen for my sisters and I to get all the ones that were available: Diphtheria – Pertussis – Tetanus (DPT) and smallpox, and then polio when it rolled out in the mid-1960s (I remember lining up at the elementary school to get the sugar cube). My father had almost died as a very young child and my mother always thought, based on his mother’s description, that the cause was probably whooping cough (pertussis) which was before the vaccine was widely available. The ‘childhood diseases’ (measles, chicken pox and mumps) required another strategy for mothers of that era: expose their children to those diseases to develop immunity to them by being sick with the disease. It was a risk but, in many cases, not as great a risk as having the diseases as an adult. I can remember being very sick with rubeola --- missing a few weeks of kindergarten. One of my sisters had a memorable case of mumps with a lot of neck swelling – but I didn’t have any symptoms at all which worried my mother because she had no way of knowing if I had developed immunity or not; years later in the 1980s, I got tested for mumps immunity during a pre-pregnancy appointment and evidently I had immunity (so no need to get a vaccination that did exist by that time).

In the 1960s at least 2 of my grandparents had pneumonia and were hospitalized. Would the vaccine we have today made it less severe or prevented it? There was a lot less antibiotic resistance in the 1960s so perhaps antibiotics were more reliable to helped them recover.

Now there are new forms of the old vaccines (except for smallpox which is no longer a circulating disease as it was in the 1960s) and new ones too. A lot of the childhood diseases are easily prevented. There are vaccines that are honed for older people too – applicable to my life stage: flu, shingles, pneumonia, RSV and COVID. I appreciate these developments since I am concerned about antibiotic and antiviral resistance; I prefer to stay well --- reduce the times I need treatment for an illness and vaccinations are a way to do that…along with maximizing the nutrition I am getting from my diet (with some supplements). Another strategy is to avoid or mask in times and places where I am likely to encounter people that are sick (indoor crowds particularly in the wintertime).

I am grateful that that are vaccinations available to prompt my immune system…so that I don’t have to be sick to gain immunity!

Could the world famous Roman Baths help scientists counter the challenge of antibiotic resistance? – A diverse array of microorganisms were found in the hot waters of the Roman Baths. Tests showed 15 of the isolated bacteria -- including examples of Proteobacteria and Firmicutes -- displayed varying levels of inhibition against human pathogens including E.coli, Staphylococcus Aureus and Shigella flexneri.

The Changing Nature of Wilderness - The U.S. government has begun to acknowledge the Indigenous history of ‘wilderness’ areas and, in some (very few) cases, restored land to native tribes or created co-management agreements.

Nearly 25% of land in Africa has been damaged – What’s to blame, and what can be done - The “big five” drivers of land degradation globally and in Africa are:

• biological invasions, where plant species have spread outside their indigenous area and disrupted the services provided by ecosystems

• climate change driven events, such as intense droughts and severe fires

• extractive activities, such as mining and over-harvesting

• habitat transformation or fragmentation, including deforestation and poor agricultural practices

• pollutants such as sulfur dioxide, and eutrophication – where algae and other plants take over plant life.

The Hunt: Genghis Khan’s Final Resting Place - His last wish was to be buried in secret, something his soldiers accomplished in two ways: by killing everyone they met enroute to the gravesite, and then trampling that site under the hoofs of their horses until no trace was left. Although tomb culture, inherited from the neighboring Chinese, was well-established by the time Genghis Khan was born, many were constructed underground, some at a depth of more than 65 feet. Most Mongolians today would prefer that Genghis Khan’s tomb stayed hidden. Not because discovering it would unleash an ancient curse—a superstition that was actually quite widespread in Soviet times—but simply out of respect for the historical figure’s dying wish.

Airplane noise exposure may increase risk of chronic disease - Research has shown that noise from airplanes and helicopters flying overhead are far more bothersome to people than noise from other modes of transportation, and a growing body of research suggests that aircraft noise is also contributing to negative health outcomes.

New fossils show what Australia’s giant prehistoric ‘thunder birds’ looked like – and offer clues about how they died out - While the birds had broad, short toes and hoof-like claws for moving across open ground between bodies of water, their partial reliance on freshwater and new plant growth would have become more difficult as ponds and lakes shrunk and disappeared.

Phoenix Heat Deaths Rose by 1,000 Percent in 10 Years - Relentless heat led to 645 deaths last year in Maricopa County, the most ever documented in Arizona’s biggest metropolitan area. Almost half of the victims last year were homeless — 290 people. Twenty died at bus stops, others were in tents, and an unrecorded number of people were found on the pavement, prone as if on a baking stone.

Warming Brings Early Bloom to Bulgarian Rose Fields – Bulgaria is a top producer of rose water and rose oil. To produce these goods, pickers must harvest the flowers early in the morning, when their petals are richest in oil. After a mild winter and warm spring, pickers in Bulgaria’s Rose Valley have headed to the fields around three weeks earlier than normal.

Then and Now – Eye Care

My third-grade teacher was the person that realized I needed glasses – when I couldn’t ever get the right answer during multiplication flashcard drills! That was in the mid-1960s. I remember my first frames were white plastic with tiny pink dots and the lenses were easily scratched. Later in the decade I was wearing rigid contact lenses (soft ones did not exist yet); they provided the best correction for me because they corrected astigmatism perfectly with their rigid surface. In the later 1970s I switched to soft contacts for comfort…but they were never as perfect as the rigid lenses.

These days I am wearing glasses except for close work. For photography – I often look over my glasses to the camera’s screen! I have two pair: single vision computer glasses and progressives with magnetically attached tinted lenses. Doing most of my reading on screens is easier for me than paper-based materials; the brightness of the screens is helpful.

At some point I will need cataract surgery. My dad had his cataract surgery in his mid-70s, but my mother didn’t need it until her 80s. One of my younger sisters had it recently so I know what to expect…however my eye doctor can still correct my vision to 20/20 with glasses so it might not be that soon. Whenever I have it – I hope to enjoy at least some years without having to wear glasses or contacts (except sunglasses); it will be a welcome break after 60+ years.

Shasta Lake Filles Up Again - After consecutive wet winters in Northern California, Shasta Lake filled up for the second year in a row, in time for summer 2024. The healthy cache of water in back-to-back years was a welcome turnaround from drought conditions and low lake levels in 2019–2022.

The chemistry of hydrangea colors – This works for the Asian hydrangeas….not the North American natives (oak leaf and wood hydrangeas).

Are there long-terms health risks to using Botox? - Botox is the most common cosmetic procedure performed worldwide, with nearly three million injections estimated to take place each year. It works by blocking signals from the nerves that control the facial muscles. The muscles relax, and fine lines and wrinkles disappear. Very little is known about the long-term health effects of taking Botox, as most clinical trials only follow up on patients for six months or so. However, some studies have found that long-lasting cosmetic use of botulinum toxin can trigger permanent changes in facial expression, with persons no longer able to flex their facial muscles.

How a Small Herd of Romanian Bison Is Locking Away Thousands of Tons of Carbon - European bison were reintroduced to the Țarcu Mountains, at the southern end of the Carpathian range, in 2014. Now numbering 170, the bison are reshaping the mountain landscape in ways that are helping clean up emissions: the Țarcu grasslands are capturing roughly 10 times as much carbon as they were before bison were reintroduced.

Preserving The Thermal Springs And Bathhouses Of Hot Springs, Arkansas – This post from National Parks Traveler came out while my daughter and I were in Hot Springs. I saw it after I got home.

How Can You Stop a Disease-Carrying Mosquito? – Hawaiian honeycreepers are dying of avian malaria spread by mosquitos. Now there is a project that is releasing male mosquitoes (they don’t bite and don’t spread diseases, females are the ones that bite/feed on blood) that causes breeding to fail – thus causing the mosquito population to crash. Even if this is successful, there is more to do for the birds to thrive: forest restoration, keeping weeds out, eliminating invasive pigs, some captive breeding of the birds.

Blood pressure drugs more than double bone-fracture risk in nursing home patients - The medications tend to impair balance, particularly when patients first stand up and temporarily experience low blood pressure that deprives the brain of oxygen. Interactions with other drugs and low baseline balance in many nursing home patients compound the problem. A combination of less medication and better support could significantly reduce the problem.

Hurricanes, heatwaves and rising seas: The impacts of record ocean heat - Every day since late March 2023, global ocean surface temperatures have set new records for the hottest temperature ever recorded on that date….and the repercussions are already beginning.

Fewer Than 100 Cigar Orchids Found In Big Cypress National Preserve - A months long search for rare cigar orchids in Big Cypress National Preserve in Florida has turned up 85 of the plants the state of Florida considers endangered. No plant had produced any fruit in the 2021 and 2022 seasons.

Lead Pipes Make Up Nearly One Tenth of US Water Service Lines - Improvements to the 1991 Lead and Copper Rule proposed in late 2023 could finally require water systems to provide accurate information and enforce the replacement of lead pipes. However, a proposed exemption would give cities like Chicago an extension, letting them take multiple decades to replace infrastructure.

Insurance Companies: Consider Climate Risk Events As “Constant Threats” - Up until recently, most people weren’t concerned with how their ability to be insured would change — until catastrophic climate disasters began to wreak havoc on communities around the country. I am very glad I don’t own property in Florida or south Texas or California!

New Constitution Gardens (in Washington DC) Will Be a Biodiversity Mecca – Glad there are plans to improve the area. I always enjoyed it even though it was beginning to show its age in the 1990s and early 2000s when we lived in Maryland and visited with our young daughter.

Stunningly Preserved Ancient Roman Glassware Turns Up in a French Burial Site – Found during construction of a new housing development. I am always amazed at how durable a material we normally thing of as ‘breakable’ can be!

Cicada dual emergence brings chaos to the food chain - Cicada emergences can completely rewire a food web. For predators, these emergences are a huge boom in resources. It's basically like an all-you-can-eat buffet for the hungry predator. A study, published in 2023, found the emergence of periodical cicadas changes the diets of entire bird communities. Scientists have found that wild turkeys, for example, will capitalize on the bounty, leading to a wild turkey boom. However, caterpillars, usually preyed on by birds, were left off the dinner menu and their numbers more than doubled. This in turn led to damage to trees caused by out-of-check caterpillar populations. Rising temperatures will lead to periodical cicada emergences starting earlier in the year, experts believe, as well as an increase in unexpected, "oddly-timed" emergences.

Earlier Springs Cause Problems for Birds - As climate change warms our planet, causing spring to arrive weeks earlier than it has historically, birds are struggling to keep up. It’s not just the green vegetation they miss, but the pulse of protein-rich insects many bird species consume on both their breeding grounds and their migratory stop-over points. Birds will still breed but not quite as successfully because food will be more limited. Instead of chicks hatching as insect populations boom, those chicks may catch the end of the insect pulse.

Why you should let insects eat your plants – I skew the additions to my yard toward native plants….and let whatever insects show up enjoy. My community sprays for mosquitos so there probably is some reduction of other insects because of that. But there are enough left to support a barn swallow (and other insect eating birds) flock in our community.

Quantifying U.S. health impacts from gas stoves - Even in bedrooms far from kitchens, concentrations of nitrogen oxide frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off. All the houses I’ve purchased as an adult, have had electric stoves/ovens except one and I only lived there for 3 years. But – in the 1950s and 1960s, my parents had gas stoves/ovens. Back then the houses were not as airtight as they are now so that might have reduced our exposure; my sisters and I never had asthma or other breathing problems, fortunately.

Inside the exquisite Tibetan monasteries salvaged from climate change – Built in the 1300s, the monasteries are impacted by a significant increase in the intensity of storms and rainfall across the region. Increased rainfall saturates the rammed-earth buildings, as moisture in the soil is drawn upward into the walls, leading to issues such as leaking roofs and rising damp. Local people have gained diverse skills, from reinforcing walls to crafting metal statues and restoring paintings. Over the past 20 years, a team of local Lobas trained by Western art conservationists have replaced the old, leaky roofs of the temples with round timbers, river stones, and local clay for waterproofing, and have restored the wall paintings, statues, sculpted pillars and the ceiling decorations, giving these centuries-old monuments a new life.

Possible Conch Shell Communication in Chaco Canyon Explored - The settlements of Chaco Canyon that spread around each sandstone great house fit into the sphere of sound produced by conch shell trumpet blasts; perhaps the settlements were designed to ensure that every resident could hear the notifications.

Do societies grow more fragile and vulnerable to collapse? - The world is hardly immune to increasing inequality, environmental degradation, and elite competition – all factors which have been proposed as precursors to collapse earlier in human history. Industrialized production, enormous technological abilities, as well as professional bureaucracies and police forces will all likely create more stable, resilient states. However, our technology also brings new threats and sources of vulnerability, such as nuclear weapons and the faster spread of pathogens. We also need to be wary of celebrating or encouraging the entrenchment of authoritarian or malevolent regimes. Resilience and longevity are not de-facto positive.

Solving the riddle of the sphingolipids in coronary artery disease - Boosting levels of a sphingolipid called S1P in artery-lining endothelial cells slows the development and progression of coronary artery disease in an animal model.

“Porcelain Gallbladder” Identified in Mississippi - Identified among a woman's 100-year-old bones exhumed from the cemetery at the site of the Mississippi State Lunatic Asylum. A porcelain gallbladder forms through calcium build-up in the wall of the organ, which causes it to harden.

World's chocolate supply threatened by devastating virus – Oh no! About 50% of the world's chocolate originates from cacao trees in the West Africa countries of Ivory Coast and Ghana. The damaging virus is attacking cacao trees in Ghana, resulting in harvest losses of between 15 and 50%. Farmers can combat the mealybugs the spread the virus by giving vaccines to the trees to inoculate them from the virus. But the vaccines are expensive, especially for low-wage farmers, and vaccinated trees produce a smaller harvest of cacao.

WHO redefines airborne transmission: what does that mean for future pandemics? - Virologists now acknowledge that SARS-CoV-2 spreads mostly by airborne transmission of small particles that are inhaled and that can remain in the air for hours — a method that was previously called ‘aerosol’ transmission. It also spreads by larger ‘droplets’ of virus-containing particles on surfaces, including hands, or ejected over short distances. The WHO document sets an important benchmark for how the world responds to the next pandemic. “The next pandemic will most likely be a respiratory virus again because that’s normally the pathogen that mutates the fastest.” The report’s clarity around transmission will help public health providers to respond appropriately. “They will then consider masking early, they’ll consider ventilation early, they’ll consider all these precautions early because a precedent has been set already.”

Human muscle map reveals how we try to fight effects of aging - As we age, our muscles progressively weaken. This can affect our ability to perform everyday activities like standing up and walking. However, this study also discovered for the first time several compensatory mechanisms from the muscles appearing to make up for the loss.

USDA announces new school meal standards that call for less sugar, salt in students' food - Schools also have the option to require locally grown, raised or caught agricultural products that are unprocessed, while the new standards limit the percentages of non-domestic grown and produced foods that schools can serve to students.

Plastic-choked rivers in Ecuador are being cleared with conveyor belts - Azure system's simple design has the capacity to stop and collect around 80 tons of plastic per day. At this particular point in the San Pedro River, the most it's collected in a day has been 1.5 tons of plastic and synthetic fabrics – that's roughly the same weight as a female hippopotamus. The Azure system is a boom device that stretches across the river to stop objects floating on the surface. It extends down 60cm (2ft) into the water, allowing fish and other organisms to move freely below, and is placed at an angle allowing the natural water flow to direct all debris into one corner of the riverbank.

First glowing animals lit up the oceans half a billion years ago - Some 540 million years ago, an ancient group of corals developed the ability to make its own light. Bioluminescence has evolved independently at least 100 times in animals and other organisms. Some glowing species, such as fireflies, use their light to communicate in the darkness. Other animals, including anglerfish, use it as a lure to attract prey, or to scare away predators. However, it’s not always clear why bioluminescence evolved. Take octocorals. These soft-bodied organisms are found in both shallow water and the deep ocean, and produce an enzyme called luciferase to break down a chemical to make light. But whether glowing octocorals use their light to attract zooplankton as prey or for some other purpose is unclear.

Peatlands Are One of Earth’s Most Underrated Ecosystems - Peatlands are spongy, waterlogged soils composed in part of decaying plant matter. They’re found all around the world, and despite covering only 3% of Earth’s surface, store around 30% of all the carbon on land.

FDA urges Congress to pass bill mandating food manufacturers test for lead – I am surprised Congress did not pass this already. According to the U.S. Disease Control and Prevention, there have been at least 519 confirmed, probable and suspect cases of lead and chromium poisoning traced to imported applesauce pouches produced by brands WanaBana, Schnucks and Weis. Lead exposure in children is associated with learning and behavior problems, as well as hearing and speech issues and slowed growth and development.

Retention ponds can deliver a substantial reduction in tire particle pollution - The presence of wetlands and retention ponds alongside major highways led to an average reduction of almost 75% in the mass of tire wear particles being discharged to aquatic waters. Tire wear particles significantly outweighed other forms of microplastics, such as plastic fibers and fragments.

Climate change is fueling the US insurance problem – I’ve seen more articles about this recently….there is no good news re insurance…nothing that can overcome what climate change is doing. One state-level action that could help mitigate the impacts of climate change is the implementation of flood disclosures. Organizations like the Natural Resources Defense Council have urged states to require flood disclosure polices during property sales to help buyers decide whether buying is worth the risk. Research has shown disclosure can devalue flood-prone properties and discourage development in risky areas. Even though the number of states requiring flood disclosure policies is slowly increasing, Florida remains noticeably absent, and one-third of states still have no requirement that sellers must disclose a property's flood risk to potential buyers.

Does the time of day you move your body make a difference to your health? – Maybe – for people living with obesity.

How the iron lung paved the way for the modern-day intensive care unit – The iron lung was first used to save the life of a child in 1928. It swiftly became a fixture in polio wards during the polio outbreaks of the subsequent decades, particularly from 1948 until the vaccine was developed in 1955. And its creation paved the way for many subsequent medical innovations. Some patients spent just a short time in the iron lung, perhaps weeks or months until they were able to regain chest strength and breath independently again. But for patients whose chest muscles were permanently paralyzed, the iron lung remained the key to survival.

Food security in developed countries shows resilience to climate change - Data on American wheat production, inventories, crop area, prices and wider market conditions from 1950 to 2018, together with records of annual fluctuations in the weather for the same period reveals strong evidence of an increase in weather and harvest variability from 1974 onwards. However, Wheat prices remain relatively stable, along with the price of associated goods mainly due to farmers and agricultural industries providing a buffer, smoothing out any bumps in the supply of grain to retailers and consumers.

Where the Xerces Blue Butterfly Was Lost, Its Closest Relative Is Now Filling In - Silvery Blues collected 100 miles south of San Francisco were released at a restored a swath of dunes in the Presidio, a former military base, trying to bring back native wildlife. They will pollinate native flowers and form a critical link in the food chain there.

Colorless, odorless gas likely linked to alarming rise in non-smoking lung cancer - 5-20% of newly diagnosed lung cancers occur in people who have never smoked, many of whom are in their 40s or 50s.  Non-smoking lung cancer cases is likely linked to long-term, high exposures of radon gas. This colorless, odorless gas is emitted from the breakdown of radioactive material naturally occurring underground that then seeps through building foundations. The gas can linger and accumulate in people's homes and lungs silently unless they know to test for it. We had our Missouri house tested and radon remediation installed before we moved it!

Contents of Roman Lead Coffin Examined in England - The examination of the contents of a Roman lead coffin discovered in 2022 in the city of Leeds has identified the partial remains of a child (about 10 years old). The initial evaluation of the coffin’s poorly preserved contents found the remains of a woman between the ages of 25 and 35 at the time of her death some 1,600 years ago, a bracelet, a glass bead necklace, and a finger ring or an earring.

Feral Hogs to Be Removed from Congaree National Park – My husband and I visited Congaree in 2008 and I vividly remember the feral hogs. Evidently action is being taken to remove them. They have become a pervasive problem to both the park and surrounding landowners, routinely causing widespread damage to land and water resources both within and outside of the park. Recent observations have shown that they have begun to cause more extensive damage to areas near the Harry Hampton Visitor Center, including areas where synchronous fireflies are active and where restoration of longleaf pine is ongoing.

What four decades of canned salmon reveal about marine food webs - The cans contained fillets from four salmon species, all caught over a 42-year period in the Gulf of Alaska and Bristol Bay. Researchers dissected the preserved fillets from 178 cans and counted the number of anisakid roundworms -- a common, tiny marine parasite -- within the flesh. The parasites were killed by the canning process but still visible… counting them is one way to gauge how well a marine ecosystem is doing.

In the 1960s, my mother did the grocery shopping for the family – usually going once a week.  I went with her occasionally but not often. She usually shopped while my sisters and I were in school. Her favorite grocery store was Safeway. I am now shopping at Walmart most of the time since it is the closest grocery store to me and once a week is still my goal. The hours my The Walmart is open from 6AM-11PM, 7 days a week; the hours grocery stores were open in the 1960s was a lot less than that and there were items they couldn’t sell on Sundays if they were open then (‘blue laws’ in Texas).

The carts were similar in design to the larger ones in most stores now although they were all metal (no plastic) and did not have seatbelts for young children. Most grocery stores now  have a few smaller carts along with the larger ones but I usually am buying enough that I get a large cart.

My mother always had a list that accumulated over the week; most of the time she made the additions to the list but as my sisters and I got old enough, we sometimes wrote in items. Now I use the OurGroceries app so that my husband and I can add items to the list from any of our devices and I use my phone when I am in the store rather than a piece of paper.

My mother only bought food at the grocery store…not toiletries or over-the-counter medications; those were purchased at a drug store which also included a pharmacy. I buy many non-groceries during my weekly shopping now; toiletries are frequently on the list, but I sometimes buy clothes or office supplies as well. It’s an advantage of shopping at Walmart rather than a grocery store. We still pick up our prescriptions at a CVS; the pharmacy at Walmart is not open at the time I usually shop (between 7 and 8:30 AM on Friday mornings).

At checkout, a cashier had to enter the price of each item on the register and the strip of paper that my mother was handed at the end only included the prices and the total. She paid with cash or wrote a check. Now I scan my purchases myself, use a credit card to pay for them, and get an itemized list that includes an abbreviated description of each item along with the total.

Mother’s purchases were put in brown paper bags by the cashier. Now the store provides single-use plastic bags; I’ve used my own bags for more than a decade (they are stronger, and I don’t have to take precautions to contain the single-use bags from littering and polluting the environment). I put my items into my bags after I scan them. All the refrigerator items go into an insulated bag and the remaining items are grouped into bags to make unloading easier once I get home (and to make sure bread, chips, and eggs are not damaged in transit).

There was a lot less plastic. Milk came only in cartons (waxed…not plastic coated) and juices and soft drinks came in glass. Canned foods were purchased frequently, and the cans were not lined with plastic. The produce section included mainly seasonal foods along with ones that could be easily stored/transported (like bananas). Broccoli was something we had periodically as a frozen vegetable, and it was packaged in a box rather than a plastic bag.  We enjoyed strawberries seasonally or frozen (in a box); now my husband likes the frozen ones (in a plastic bag) more than he likes fresh ones! Plastic is the dominate packaging now: jugs of milk, bottles of water/soft drinks/juice, bags of frozen veggies and fruit, robustly sealed meats, bags of snacks and fresh vegetables/fruits, jars of peanut butter. Sometimes there is an option to buy in class jars but most of the time there is no choice; the packaging is plastic.

The most common type of bread was white; my mother wanted ‘whole wheat’ and bought Roman Meal when she could find it. I buy Dave’s Sprouted organic bread….avoiding a lot of added chemicals that have been introduced over the years to keep bread from molding or otherwise ‘improving’ it in some way (‘improving’ is in quotes because many breads cross over into the ultra-processed realm with the additions that are quite common today).

Some of the brands are still around: Cambell’s, Nabisco, Kelloggs, Green Giant. I don’t buy them as often as my mother did…only Cambell’s Tomato Soup and Green Giant Niblets Corn for my husband.

There are a lot of products in the grocery store that were not available in the 1960s…most of them ultra-processed and they fill up whole aisles of the grocery store. It requires some willpower to steer clear of those (although it gets easier over time). On the healthier side, it is now easier to find international foods (salsas and tortillas, etc.) and things like boneless chicken breasts…a lot more options when it comes to pasta, sauces in glass jars, greens (kale and arugula were not in grocery stores in the 1960s), grains/seed (quinoa and chia are new…’chia pets’ were not introduced until the later 1970s), and no salt seasonings. There are now targeted foods for special diets; for example, milk that includes Lactaid for those that are lactose intolerant and protein shakes for diabetics or those dieting and concerned about getting adequate protein.

My mother was very conscious of nutritional guidelines; she had taken home economics courses in college. We had some form of protein at every meal along with fruits and vegetables and grains. Sugary items were only for special occasions. There were seasonal fresh foods, but she relied on canned goods more than we do now, particularly during the winter. Both sets of grandparents had big gardens and we enjoyed their bounty whenever we could – supplementing what was purchased at the grocery store; we knew how food was grown and a little of how it was preserved (canned) for later. Now we buy more fresh or frozen fruits and veggies rather than canned because they are readily available during the whole year. I also buy organic as much as I can….something that didn’t exist in the 1960s.

Groceries have changed significantly since the 1960s. Availability of healthy foods is probably better now – although it takes more attention/knowledge to avoid the ultra-processed foods that are often intermingled with the healthy food.

Touching Image of Intergenerational Love Wins Black and White Minimalist Photography Prize – Minimalist…but powerful.

How an English castle became a stork magnet – 30 White Storks from a rescue project in Poland introduced in the rewilded habitat at Knepp Castle in southern England in 2016. At one point, storks even built nests on Knepp Castle itself although they usually build their nests in the crown of huge oak trees. The young storks started migrating in 2019. The colony has grown to about 80 storks…and is the first breeding colony in Britain in 600 years.

Evidence for Domesticated Chickens Dated to 400 B.C. - A study of eggshell fragments unearthed at 12 archaeological sites located along the Silk Road corridor in Central Asia.

Noisy Summer Ahead for U.S. as Dueling Broods of Cicadas Emerge - It is the first time these two broods are going to be emerging in the same year since Thomas Jefferson was in the White House. Mating season will last until July.

California’s Live Oaks in Focus - Some centuries old, the oaks are magnificent giants that can grow up to 100 feet tall and are what remains of a forest that once blanketed the region.

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects - Analyzing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health. Microparticles from car tires, pesticides from farmers' fields, and toxins from harmful algal blooms are just some of the organic chemicals that can be detected using the new approach.

Cars & Road Trips Made a Huge Difference in Women’s History – One of the first cars ever built got taken by a woman, without permission, on the world’s first road trip! Bertha Benz wanted her husband’s invention to be seen out in the country so people would buy it, but her husband Karl Benz was being timid about it. So, she took the car out on a road trip with her kids.

Common household chemicals pose new threat to brain health - The new study discovered that some common home chemicals specifically affect the brain's oligodendrocytes, a specialized cell type that generates the protective insulation around nerve cells. Loss of oligodendrocytes underlies multiple sclerosis and other neurological diseases. They identified chemicals that selectively damaged oligodendrocytes belong to two classes: organophosphate flame retardants and quaternary ammonium compounds.

The Soundtrack of Spring on the Platte River – Sandhill cranes staging last month along the Central Platte River in Nebraska. So many birds….lots of sound.

These Are the Most Polluted National Parks – Many national parks are suffering from air pollution and facing threats stemming from human-caused climate change. 98 percent of parks suffer from visible haze pollution, while 96 percent are grappling with ozone pollution that could be harmful to human health. Four of the nation’s parks with the unhealthiest air are in California: Sequoia and Kings Canyon National Park, Joshua Tree National Park, Mojave National Preserve and Yosemite National Park. Another California site, Death Valley National Park, also made the top ten list. 57 percent of national parks are facing at least one threat stemming from climate change that could permanently alter its ecosystems, with many parks grappling with multiple issues at the same time. Invasive species were the most prevalent issue.

What do terracotta warriors tell us about life in ancient China? – Discovered 50 years ago…they are a snapshot of the soldiers of Qin – the feudal state that unified China, for the first time in 221BC under the country's first emperor Qin Shi Huang – from the soles of their shoes to their candy-colored clothes to the bronze weapons buried with them to their distinct facial features. 2,000 terracotta warriors have been excavated but more are uncovered every year.

This Map Shows Where Planting Trees Would Make Climate Change Worse - Trees draw down carbon dioxide from the atmosphere, helping to keep warming in check. But their dark, green leaves also absorb heat from sunlight. Snow and sand, by virtue of their light color, reflect more sunlight back into space. As such, trees planted in snowy areas or in the desert will absorb more sunlight than their surroundings, which may negate the climate benefits of soaking up carbon dioxide.

These 3,000-Year-Old Treasures Were Forged from Meteoritic Iron - In the 1960s, researchers discovered a trove of Bronze Age treasure in Villena, Spain. New research has revealed that some of them made between 1400 and 1200 B.C.E. were forged from iron from a meteor that struck Earth a million years ago. Who manufactured them and where this material was obtained are still questions that remain to be answered.

Vernal Pools Make Your Garden Sing - It’s not just frogs that are making homes in these little pools of water. Less vocal species like salamanders, dragonflies, fairy shrimp, and even dozens of native plants are there too. Even more species than that can be found simply visiting the pool for a drink or snack, including great blue herons, wood ducks, and box turtles.

Return of Trees to Eastern U.S. Kept Region Cool as Planet Warmed - Over the 20th century, the U.S. warmed by 1.2 degrees F (0.7 degrees C), but across much the East, temperatures dropped by 0.5 degrees F (0.3 degrees C). A new study posits that the restoration of lost forest countered warming, keeping the region cool. Still, the return of trees can only partially account for the drop in temperature. Other possible explanations include the growth of irrigation, a source of water vapor, and the uptick in particulate pollution, which reflects sunlight, thereby cooling the air.

Sweetened drinks linked to atrial fibrillation risk - 20% higher risk of irregular heart rhythm, known as atrial fibrillation, among people who said they drank two liters or more per week (about 67 ounces) of artificially sweetened drinks. The risk was 10% higher among people who said they drank similar amounts of sugar-sweetened beverages.

Measles outbreaks and what parents need to know - Measles can lead to complications such as ear infections, diarrhea, pneumonia, and encephalitis (brain swelling). One to three of every 1,000 children infected with measles dies. More than 97 percent of the people who have had their two shots of the vaccine never get measles.

A new world of 2D material is opening up - 2D materials have shown great potential for an enormous number of applications. You can imagine capturing carbon dioxide or purifying water, for example. Now it's about scaling up the synthesis and doing it in a sustainable way.

In Cleveland, mushrooms digest entire houses: How fungi can be used to clean up pollution - Fungi can eat the noxious waste from abandoned homes. Heavy metals and other toxins are extracted and captured in the mushrooms that grow, while the substrate leftovers, including the mycelium, are compacted and heated to create clean bricks for new construction. The resulting "mycoblocks" have a consistency akin to hardwood and, depending on the specifics of the manufacturing process, have been shown to be significantly stronger than concrete.

Arctic nightlife: Seabird colony bursts with sound at night - Acoustic recordings of a colony of little auks reveal their nocturnal activities and offer valuable monitoring means for avian biology in the Arctic.

Ten Little Celebrations – March 2024

Picking 10 little celebrations is only challenging because there are so many of them to choose from! I help myself by only noting one each day, but I realize when I look at the list at the end of the month that there are even more, in retrospect, worthy of celebration. Here are the top 10 for March 2024.

My mother’s life. The phrase ‘celebration of life’ is more like a savoring because there is an overlay of grief that is part of every gathering after a death. I stayed focused on making sure that someone was with my dad for the duration and providing narration of the images in the slideshow for him…varying what I said a bit each time it repeated and realizing that she had a very full 92 years!

Getting the check deposited after the sale of my parents’ house. What a relief to not be carrying around a big check!

Home again. I made multiple short trips to Dallas for various reasons and was always very glad to be home again. Even though the time away is only a couple of days, the stress of driving, my task while in Dallas, and staying in a hotel takes a toll. I don’t really relax until I am at home. Hopefully, when I am only going down to see my dad, it will not be as stressful.

Sequiota Cave Boat tour. What a great tour. I liked the non-commercial nature the tour…seeing the tiny bats roosting.

Springfield Botanical Gardens. Full of spring blooming trees.

Dickerson Park Zoo. My daughter gave us a membership for Christmas, so we’ll be enjoying the zoo often over the next year. I liked the roaming peacocks (and other things too). The post about this visit is coming day after tomorrow.

Feeling better. I got sick with something that caused sinus and throat problems. I tested for COVID for 3 days…and was negative for that. And then I recovered rapidly and I celebrated. Also celebrated that my husband did get whatever it was.

Creating more hosta locations. I divided some of my hosta plants as they first began to come up and was pleased that the new plants adjusted very quickly to their new space. I am looking forward to their lush growth this summer…and will divide more plants next spring!

Burning sticks. I enjoyed the fire in my chiminea after cleaning up the small branches and pine cones around my yard….celebrating with some pictures of the fire!

Butterfly and pollinator seeds planted. I celebrated getting the beds prepared and the seeds planted…right at the mid-March suggested planting deadline.

Floating Solar Array Is Designed to Take the Rough Stuff - Rich opportunities for solar co-location with offshore wind. By combining floating solar with offshore wind farms and thereby leveraging the same energy infrastructure and export cables, the resulting energy production capacity per used area could be drastically improved. Prototype has been developed…should be in the water by June 2024.

Pregnancy advances your ‘biological’ age — but giving birth turns it back - Brewing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA — changes similar to those that are a hallmark of getting older. But new research shows that, several months after a person gives birth, the chemical patterns revert to an earlier state.

Did You Know Sandhill Cranes Dye Their Feathers? – The birds rub iron rich mud onto their feathers…staining them. And some trivia about sandhill cranes at the Platte River (Nebraska) in the early spring:

• The birds find a lot of waste corn in farm fields, as well as small invertebrates in marshes near the river. A crane can add 20 percent to its weight during two or three weeks in the area.

• At night, the cranes move to the Platte River for safe roosting in the shallow water.

• Sandhill cranes are the most numerous of the world’s crane species.

• In the Central Flyway, more than 500,000 cranes – more than 80 percent of their population.

The heat index -- how hot it really feels -- is rising faster than temperature - Researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days! Arizona's most populous county, covering most of Phoenix, reported that heat-associated deaths last year were 50% higher than in 2022, rising from 425 in 2022 to 645 in 2023. Two-thirds of Maricopa County's heat-related deaths in 2023 were of people 50 years or older, and 71% occurred on days when the National Weather Service had issued an excessive heat warning. With climate change, the relative humidity remains about constant as the temperature increases, which reduces the effectiveness of sweating to cool the body.

158 Cherry Blossom Trees Will Be Cut Down in D.C. in Effort to Withstand Sea-Level Rise – Part of the project to reconstruct a seawall around the Tidal Basin.

Landscape Architecture Strategies Reduce Impacts of Dangerous Extreme Heat – And these apply to what we do in our yard too!

• Increase tree percentage in parks and green spaces

• Provide shade on sites

• Use plant materials and water instead of hardscape

• Switch to green ground cover, including grasses and shrubs

Plastics Contain Thousands More Chemicals Than Thought, and Most Are Unregulated – Scary! The report also highlights 15 chemical priority groups of concern. These include phthalates, which are used to make plastics more durable and have been found to affect the reproductive systems of animals, as well as per- and polyfluoroalkyl substances (PFAS), which break down very slowly over time and have been linked to health issues including reproductive and developmental problems and increased cancer risk.

Only seven nations meet WHO air pollution standards – The US is not one of the seven: Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand. Bangladesh, Pakistan, India, Tajikistan and Burkina Faso were the top five most polluted countries in 2023 with PM2.5 levels nine to 15 times higher than the WHO's standard. Columbus, Ohio, was the most polluted major city in the United States, while Las Vegas was the cleanest and Beloit, Wisconsin polluted U.S. city overall.

Possible Neolithic Body Piercings Unearthed in Anatolia – Over 11,000 years old…found near ears and chins of human remains.

Under Threat in Their Native California, Giant Sequoias Are Thriving in Britain - First introduced to country estates in the 19th century, half a million sequoias now grow in Britain, compared to just 80,000 along the western flank of the Sierra Nevada in California, where they are increasingly imperiled by warming. Up to a fifth of all large giant sequoias in California died in wildfires in 2020 and 2021. The trees in Britain are still relatively young — sequoias can live for more than 3,000 years — and squat. In Britain’s cool, mild climate, sequoias are growing nearly as fast as in California.

Whales That Go Through Menopause Live Longer and May Help Care for Grandchildren - Female tooth whales that go through menopause (narwhals, killer whales, false killer whales, short-finned pilot whales and beluga whales) have longer lifespans than those that don’t, surviving decades past their reproductive prime!

A healthier diet is linked with a slower pace of aging, reduced dementia risk - We have some strong evidence that a healthy diet can protect against dementia…but the mechanism of this protection is not well understood. This study suggests that slower pace of aging mediates part of the relationship of healthy diet with reduced dementia risk, and therefore, monitoring pace of aging may inform dementia prevention. Additional observational studies need to be conducted to investigate direct associations of nutrients with brain aging.

The next pandemic? It’s already here for Earth’s wildlife – The pathogenic strain of avian influenza has killed millions of birds and unknown numbers of mammals. Between January 1, 2003 and December 21, 2023, 882 cases of human infection were reported from 23 countries, of which 461 (52%) were fatal. To prevent the worst outcomes for this virus, we must revisit its primary source: the incubator of intensive poultry farms.

Ultra-fast fashion is a disturbing trend undermining efforts to make the whole industry more sustainable - Ultra-fast fashion is marked by even faster production cycles, blink-and-you’ll-miss-it trends, and poor labor practices. Without change, the industry will account for 26% of the world’s carbon budget for limiting global warming to 2°C by 2050. Established brands such as Gap introduce 12,000 new items a year and H&M 25,000. But Shein leaves them in the dust, listing 1.3 million items in the same amount of time.

Apples, Walnuts… and Toast? A New Study Reveals the Flavors of Ancient Roman Wine - Georgian vintners still employ a rustic approach. Grapes are crushed by hand or foot, placed in egg-shaped vessels known as qvevri, and buried for up to six months. It’s a UNESCO-recognized tradition dating back 8,000 years and researchers believe can help reveal the sight and scent of ancient Roman wine.

Mexico is suing US gun-makers for arming its gangs − and a US court could award billions in damages - In January, a federal appeals court in Boston decided that the industry’s immunity shield, which so far has protected gun-makers from civil liability, does not apply to Mexico’s lawsuit. Mexico’s lawsuit alleges that U.S. gun-makers aided and abetted illegal weapons sales to gun traffickers in violation of federal law. According to the lawsuit, feeding demand for illegal weapons is central to the industry’s business model.

Climate change reversing gains in air quality across the U.S.: study - The study finds that climate change is increasing the prevalence of two of the air pollutants most harmful to human health: particulate matter, commonly referred to as PM2.5, and tropospheric ozone. Whereas pollutants from cars and factories could be targeted by regulations over the past few decades, climate-related deterioration in air quality is a much tougher problem to solve.

Avar Grave Offers Clues to 7th-Century Heavy Cavalry - Thought to be a complete set of lamellar armor, which was made from hundreds of small iron plates, was spread out over the warrior.

How millennials could give the suburbs a much-needed makeover – The trend is to move to the suburbs and not feel like you need to go to the city to have a great dinner or to see a show or live music or the arts.

The far-reaching impacts of wildfire smoke – and how to protect yourself - One study found that a quarter of the US's PM2.5 pollution was caused by wildfire smoke. In western regions, as much as half was caused by smoke. If there is a wildfire nearby, the Centers for Disease Control and Prevention advise taking steps to limit your exposure where possible:

Choose a room to close off from outside air

Wear a tightly fitting respirator, if it is safe for you to do so

Keep track of fires nearby using services such as AirNow's fire and smoke map

Pay attention to health symptoms and seek medical care if needed

Ancient Lipstick Dating Back More Than Three Millennia Is Found in Iran – Analysis of the loose, dark purple fine powder revealed minerals (hematite, quartz, braunite, anglesite, and rare tiny crystals of galena) and vegetal fibers.

In Scotland, Renewable Power Has Outstripped Demand – A milestone for Scotland. The volume of electricity produced by renewables in Scotland was equal to 113 percent of demand in 2022. Fossil fuels still supply some electricity, helping to smooth over gaps in renewable power. Across the U.K., fossil fuel power is at its lowest level in nearly seven decades. Impressive.

Surprisingly vibrant color of 12-million-year-old snail shells – Polyenes (includes carotenoids) preserved almost unchanged…and found in fossils.

Asbestos: The strange past of the 'magic mineral' – Asbestos was woven into textiles fit for kings and used for party tricks. One 18th-Century philosopher even slept in a night-cap made from it. It was also used to make the funerary shrouds for monarchs; because it didn't burn, it helped to keep their ashes separated from the rest of the pyre. An account from Ancient Greece describes a golden lamp made for the goddess Athena, which could reportedly burn for a whole year without going out and had a wick made from "Carpathian flax" – thought to be another name for asbestos. In 1899, an English doctor recorded the first confirmed case of a death linked directly to the material – a 33-year-old textile worker who had developed fibrosis of the lungs. In the UK, all asbestos was banned in 1999, but much of the asbestos added before this date remains in place – as buildings degrade, it is posing a significant health risk.

Rise of Peru’s Divine Lords – Hilltop sites in the Andes…early examples of divine lordship - a form of leadership that would endure in Peru for more than 1,000 years.

Amid Record Drop in Fossil Power, Europe Sees Wind Overtake Natural Gas - The E.U. power sector is undergoing a monumental shift - fossil fuels are playing a smaller role than ever as a system with wind and solar as its backbone comes into view. Coal generation fell by 26 percent, while gas generation fell by 15 percent.

Student Design Competition: Integrating Solar and Agriculture - Some 2.8 gigawatts of agrivoltaics exist across the U.S. Many combine solar energy with pollinator habitat and sheep grazing. The National Renewable Energy Laboratory (NREL) is looking for new design proposals from graduate and undergraduate landscape architecture students to push the agrivoltaics envelope!

The Moon Is Shrinking, Causing Moonquakes at a Potential NASA Landing Site - Researchers examined data on moonquakes detected by lunar seismometers, which have been on the moon since Apollo program astronauts left them there more than 50 years ago. They also used mapping data from NASA’s Lunar Reconnaissance Orbiter to identify the telltale creases on the moon. Through modeling, they linked these faults to seismic activity.

Texas Reservoirs Reach Dangerous Lows - In Corpus Christi, on the south Texas coast, authorities last month stopped releasing water aimed at maintaining minimum viable ecology in the coastal wetlands, even as oil refineries and chemical plants remain exempt from water use restrictions during drought. On the lower Texas coast, the Rio Grande has not been flowing consistently, and Colorado River water releases have been minimal as that river faces shortages farther upstream.

Extreme Birding: Gull Watching at the Landfill - You can find gulls around North America (and many parts of the world), including in interior states. At least 28 gulls can be seen in North America, with additional vagrant species showing up from time to time. Individual species look different depending on age and other factors. A gull goes through three feather molts in its first year.

Poisonous Seed Stash Discovered in the Netherlands – Black henbane contained in a hollow goat (or sheep) thigh bone sealed with a plug of black birch bark…from AD 70-200.

Ocean Sponge Skeletons Suggest a More Significant History of Global Warming Than Originally Thought - An analysis of six sea sponges—centuries-old creatures with an internal chemistry that holds secrets about climate history—points to global temperatures already having increased by 1.7 degrees Celsius due to human activity --- that’s more than scientists currently agree upon….so there is a flurry of activity to corroborate the finding.

Ramping up Elder Care – February 2024

My parents have rediscovered the joy of going out to a restaurant for a meal. The weekday late lunchtime seems to work best (i.e. not crowded). It is quite a production: two elderly people with walkers…and two (or three) others with them. One of my sisters bought a small refrigerator for their room and they relish being able to put their leftovers there (and seem to prefer eating them for their next meal!). This is probably something I will try to do with them every time I visit. There are a lot of restaurants near the assisted living group home to experience.

Sometimes major bends in our life path are only recognized in retrospect; the events of January and February 2024 are a bend everyone in my family anticipated and acknowledges in real time. My sisters and I are acclimating to others providing the day to day care of our parents with their move to an assisted living home and the family has lost a long term hub for family events with the selling of their house.

• My parents moved to an assisted living group home at the end of 2023. They’ve settled into their new environment. My mother is improving; maybe it is simply a trend that started back in December, but it could also be the increased social interactions and her confidence that someone is always available to help. It is still challenging for my sisters and I to back away and not jump to assist them when we visit. The staff is helpful and patient with everyone! My dad is about the same although he was very disoriented at first; he is eating well.

• My sisters and I began to clean out my parents’ house soon after we moved them. They had lived in the house for over 30 years. There was a lot to go through. I made two short (less than a week) trips to Carrollton to help. During January we cleared most of the house by

  • Distributing furniture to family members or selling it or marking it for donation. I took two small tables, and my daughter took a larger octagon table for her office.

  • Donating clothes. There was very little that someone else in the family could wear. The closets in their assisted living rooms are filled to the brim with clothes that they wear.

  • Following the ‘bequeath’ list for decorative and kitchen items. I got 2 items from their 50th anniversary (one passed down from my maternal grandparents’ 50th), 1 from my parents’ 25th  anniversary, items that I remember from my childhood (a knife, fork and spoon of the silver plate my mother bought before she married; a orange cut glass bowl that I bought as a present to my Mother because it was her favorite color), 2 paintings my mother made (one of a dogwood blossom…and the pressed flower that I sent to her in 1984 from my Virginia house that she used as her model), the remnants of my maternal grandmother’s China….too many things to name although I am realizing that I should make a list for myself.

• The house went on the market on February 1st and we accepted a full-price offer on the 2nd. Closing was requested for 2/28. February became a sprint to clear out the two sheds on the property and donate the furniture that no one in the family wanted. I made a very focused trip to help.

  • Salvation Army came with a truck to get furniture and boxes of books. It was tricky since the city had the street in front of the house torn up (infrastructure update project). The truck managed the pickup from the alley.

  • Tools were mostly distributed to the sister that wanted them. Some were tools from my paternal grandfather.  My daughter got a telescoping tree trimmer (she has the bigger trees…but I can borrow it when I need it).

  • The trash and recycle bins were full for every pickup and some items were put at the curb in front of a neighbor’s house for bulk pickup.

  • Some odds and ends were taken to be repurposed. I got some white vertical blinds (not attached to anything…just loose pieces of blind) which I plan to cover with Zentangle patterns and hang (not sure where yet). There were three small pieces of Masonite that I got for another Zentangle project. Some pieces of wood were taken by my sisters for art projects and specific repairs at their house.

  • One sister is having the king headboard (purchased in 1963…beautiful wood) made into a display case. She also took the antique meat grinder that we found in one of the sheds.

  • Another sister is taking most of the yard equipment to distribute to her family’s houses so that it will be easier for her to do yard maintenance.

Are we through the bend….or is more to come before we settle into a new normal? As I write this my dad has tested positive for COVID-19. The symptoms were mild and initially attributed to some new eye drops. He was tested after one of my sisters that visits frequently tested positive. He is getting Paxlovid. This is the first experience with COVID for him and my mother; they are both vaccinated. Hopefully this will be a minor blip and we’ll achieve a new normal in March.

Gleanings of the Week Ending February 17, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

The lost art of the death mask – In the late Middle Ages (after 50% of the population was wiped out in 4 years by plague), death masks were created by molding wax or plaster over the face, and were a useful way of copying the features of deceased relatives, so that sculptors could use them as a reference for the lifelike portraits displayed at funerals. Then in the 18th Century, something unexpected happened: people began to value death masks for their own sake. Many death masks were turned into spooky heirlooms, while some became souvenirs that command six-figure sums to this day.

Rapa Nui’s Rongorongo Tablets in Rome Radiocarbon Dated - In the nineteenth century, Roman Catholic missionaries took four wooden tablets bearing rongorongo glyphs from Easter Island. They have recently been radiocarbon dated; three of the tablets were made from trees cut down in the eighteenth or nineteenth centuries; the fourth tablet came from a tree felled sometime between 1493 and 1509, some 200 years before the arrival of Europeans in the 1720s.

Tribe Making Play to End Oil Development at Big Cypress National Preserve - The National Park Service took charge of the land 50 years ago, which is a haven for some of Florida’s most endangered wildlife species, such as the Florida panther — but not the mineral rights under the land. Those are owned by the Collier Resources Company, which has from time to time dispatched oil companies to the preserve to look for black gold.

Bird Alert: The Search for Local Rarities – The joy of birding close to home!

Archaeologists discover oldest known bead in the Americas - At the La Prele Mammoth site in Wyoming. Made of bone from a hare. Almost 13,000 years old.

Stunning Macro Photos Pay Homage to the Frozen Beauty of Winter – A good reminder to check ice as a subject for winter photography!

Ancient pollen trapped in Greenland ice uncovers changes in Canadian forests over 800 years - The onset of the Little Ice Age around 1400 and the arrival of European settlers and subsequent intensive logging practices around 1650. The pollen in ice can be dated almost to the year it was deposited!

Back Pain Explained - Many people with degenerated discs feel no pain at all….but others have severe pain. It appears that when aging or under degenerative stress, a subset of cells in the center of the disc can release a cry for help, a particular signal that causes outside neurons to extend their axons within, allowing the brain to feel the pain inside. This work could inform future treatments for discogenic lower back pain!

PACE Makes it to Space – NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) was launched February 8…preparing to move into operational phase soon.

How our drinking water could come from thin air - The solar-powered hydropanels work by using sunlight to power fans that pull air into the device, which contains a desiccant material which absorbs and traps moisture. The water molecules accumulate and are emitted as water vapor as the solar energy raises the temperature of the panel to create a high-humidity gas. This then condenses into a liquid before minerals are added to make it drinkable. There are several startups with other approaches to produce water from air too. And they all work even with dry air.
