20 Incredible Winners From the 2023 European Wildlife Photographer of the Year Contest – Lots of natural beauty…captured in photographs.

A known environmental hazard can change the epigenetics of cells – Formaldehyde. It is a widespread pollutant - formaldehyde enters our body mainly during our breathing and, because it dissolves well in an aqueous medium, it ends up reaching all the cells of our body. It is associated with an increased risk of developing cancer (nasopharyngeal tumors and leukemia), hepatic degeneration due to fatty liver (steatosis) and asthma.

How forest schools boost children's immune systems – It seems the benefits go well beyond immune systems.  Hopefully this type of school for 3 to 5 year old will increase in availability/popularity.

Circular Maya Structure Uncovered in Southern Mexico - Similar round structures have been found at the Maya sites of Edzná, Becán, Uxmal, and Chichen Itzá.

Health Care Workers Are Burning Out, CDC Says - The CDC researchers analyzed self-reported symptoms of more than 1,400 adults in 2018 and 2022 who were working in three areas: health care, other essential services and all other professions. Workers’ self-reported poor mental health days in the past 30 days was similar across all three groups in 2022, but health professionals saw the most significant jump, from 3.3 in 2018 to 4.5 in 2022. Reports of harassment at work also spiked among health care workers over the five-year period, going from 6.4 percent to 13.4 percent.

How To Bring Back the Prairie, a Tiny Bit at a Time – The use of “prairie strips” on farms in an effort to restore a portion of the Minnesota’s remnant prairie and to soak up polluted water.

These Ten Stunning Images Prove That Small Is Beautiful – From Nikon’s Small World Photomicrography Contest. My favorite was the cuckoo wasp.

Deforestation in Colombia Down 70 Percent So Far This Year - Since taking power last year, leftist President Gustavo Petro has enacted a slate of new policies aimed at protecting Colombian forests, including paying locals to conserve woodland. The recent gains in Colombia mirror similar advances in the Brazilian Amazon, where leftist President Luiz Inacio Lula da Silva has cracked down on forest clearing; deforestation is down 50 percent through the first nine months of this year. In 2021, more than 100 countries, from Brazil to Russia to Indonesia, set a goal to end deforestation by the end of this decade, but so far forest loss has declined too slowly to stay on pace for this target.

European wildcats avoided introduced domestic cats for 2,000 years – About 50 years ago in Scotland, however, that all changed. Perhaps as a result of dwindling wildcat populations and a lack of opportunity to mate with other wildcats, rates of interbreeding between wild and domestic cats rose rapidly.

Why grazing bison could be good for the planet - The shortgrass prairie makes up 27,413 sqare miles of remote land straddling the US/Canadian border to the east of the Rocky Mountains. This rare habitat is in ecological decline. Plains bison co-evolved with the short-grass prairie. In the 12,000 years since the end of the Pleistocene, they have proven themselves to be potent ecosystem engineers. An adult bison eats about 25lb (11kg) of grass a day. The grasses adapted to their foraging. Vegetation across the plains uses the nutrients in their dung. Birds pluck their fur from bushes to insulate their nests. Bison also shape the land literally. They roll in the dust and create indentations known as "wallows" that hold water after rainstorms. After the bison move on, insects flourish in these pools and become a feast for birds and small mammals. Pronghorn antelope survive by following their tracks through deep winter snows. Replacing cattle with bison greens floodplains…setting the stage for beavers.

Water-quality risks linked more to social factors than money - Low population density, high housing vacancy, disability, and race -- can have a stronger influence than median household income on whether a community's municipal water supply is more likely to have health-based water-quality violations. Many of the water-quality challenges are downstream of demographics, with many community water systems lacking the financial, managerial, and technical abilities to address the water-quality issues.

Step Inside Artist Dale Chihuly’s Stunning Seattle Studio, Filled with an Epic Antiques Collection and His Otherworldly Glass Forms – Interesting pictures.

Archaeological Tropes That Perpetuate Colonialism - We need to start with presence rather than absence. How did Indigenous communities survive, persist, and come to live at the places where they are today? How do Indigenous people conceptualize and engage with the places of their Ancestors? What stories do they share with their grandchildren?

The US is spending billions to reduce forest fire risks – we mapped the hot spots where treatment offers the biggest payoff for people and climate – Where forest-thinning and controlled burns could have the most impact in the western US….for reducing wild-fire caused carbon loss, protecting human communities, and both.

The gold jewelry made from old phones - "We're trying to encourage the idea that one person's waste is someone else's raw material." An article about what is happening at the UK Royal Mint re circuit boards from electronic waste.

Iron Age Child’s Shoe Found in Austria – Found in a salt mine in north-west Austria…a 2,000 year old shoe that once belonged to a child that lived or worked underground.

New Satellite Tracking Air Pollution Releases Its First Images – The TEMPO (Tropospheric Emissions: Monitoring of Pollution) instrument makes hourly measurements of pollutants over North America. NASA will share observations with agencies that provide weather forecasts in hopes of reducing exposure to pollutants such as ozone.

Fine Particulates Are Slowly Killing Us All - People who live in Delhi, the most polluted big city on the planet, are living 11.9 fewer years because of air pollution. People in Bangladesh, the world’s most polluted country, stand to lose 6.8 years of life compared to 3.6 months in the United States. Acknowledging the benefits to society from burning fossil fuels in the past is no reason to continue embracing them in the future. We have created a system that kills people. We have access to clean energy technologies that do not make negative health outcomes one of their embedded features.

New cause of Alzheimer's, vascular dementia - A form of cell death known as ferroptosis -- caused by a buildup of iron in cells -- destroys microglia cells, a type of cell involved in the brain's immune response, in cases of Alzheimer's and vascular dementia.

 Windows to the Past at Great Smoky Mountains National Park – History told through structures left behind (and maintained). Forever Places. A former resident said, ““…it was more like livin’ in the Garden of Eden than anything else I can think of.”

As the Mississippi Swerves, Can We Let Nature Regain Control? - After the lower Mississippi began pouring through and enlarging Neptune Pass in 2019, sediment began flowing into a sand-and-silt-starved Delta Bay. Now the Army Corps of Engineers — breaking with tradition — is considering letting at least part of the river have its way…..a change from always ‘filling the breach’ strategy of years past that has had positive economic impacts but caused environmental problems. According to the U.S. Geological Survey, since 1932, more than 2,000 square miles of land in the Mississippi Delta have disappeared under water.

Babcock Ranch: Florida's first hurricane-proof town - When Hurricane Ian made landfall on the southwest Florida coast, it brought 150 mph winds, 17 inches of rain within 24 hours, and storm surges of up to 18 ft. It was the costliest hurricane in Florida's history, causing more than $112 billion  in damage – and at least 150 deaths. Babcock Ranch is an 18,000-acre development that was sitting in the eye of the storm on the southwest of the state just north of Fort Myers. Built to withstand powerful storms, the town came out relatively unscathed. Is this type of development going to be the only kind economically viable for states like Florida in the future?

Year-round school: Difference-maker or waste of time? – No conclusion in this article….evidently there is renewed interest in the idea in the Southeast. But – the concept is not what most people probably assume. The implementation does not involve more days in school for students and often makes childcare more difficult!

What Are Heat Pump Air Conditioners? - Modern heat pumps are superefficient and can deliver heat down to -15 degrees Fahrenheit…but I had to look to find that they can deliver cool air up to 115 degrees which should have been in the article since it was about air conditioning!

Controversial dwarfism drugs spur growth — but do they improve health? – Hard choices.

Microplastics infiltrate all systems of body, cause behavioral changes – Especially in older mice…behaviors akin to dementia in humans. The changes became more profound in older animals. The microplastics in the study were delivered orally via drinking water…and not in high doses.  It’s scary to think about how microplastics might be impacting humans too.

Can California Cropland Be Repurposed for Community Solar? – Evidently the current farming practices are not sustainable, and some farmland needs to be retired. The idea is that the already disturbed land could be repurposed for new community solar projects. I wondered where the food we now are getting from California will be grown in the future…how robust is the US food production system?

TB research shows a good diet can cut infections by nearly 50% - Improved nutrition in family members of patients in India with lung TB reduced all forms of TB by nearly 40%, and infectious TB by nearly 50%. And…for the patients: An early weight gain in the first two months was associated with 60% lower risk of TB mortality. The other benefits were higher treatment success and better weight gain. During the six-month follow-up period, a remarkable treatment success rate of 94% was achieved.

Top 10 Things You Didn’t Know About Wind Power – How many of these 10 did you know already? I knew 4 of the 10…and knew a little about several others. It’s good to see the progress being made. Kudos to Iowa and South Dakota where over 50% of their electricity generation is from wind energy.

Soils forming on the branches of trees are an overlooked forest habitat – This was a study of a tropical forest in Costa Rica, but it reminded me of a tree along a field trip hiking route in Maryland that I always pointed out to students. It was an old maple that had an indention in its trunk that contained soil about 6 feet above the base of the tree. The tree had grown some roots into that soil and there was moss there. Spider webs filled in. Once we found a shed snakeskin hanging from the area!

Dead trees around the world are shocking scientists – Hotter droughts are impacting forests more than anticipated. According to one 2019 study, global greening stopped more than 20 years ago, and vegetation has been declining since, all because of the drought-amplifying effects of warming. Forests are being forced into a transitional phase as they are impacted by the pressures of warmer temperatures, drought, fires, and insects. Perhaps the forests of the future will look very different from the forests that existed in the late 1900s.

Visiting the Grand Canyon will get more dangerous – A heat-related death was reported in July. As the summer days get hotter in the coming years, the risk will increase. I wonder if the peak visitation times at the National Park will shift to spring and fall rather than summer.

Study confirms link between concealed carry weapons and gun homicide rates – The study included 832 counties in the US from 2010 to 2018. "People aren't using concealed guns in public defensively to thwart potential homicides. Rather, having more guns in public through concealed carry appears to be more dangerous and leads to higher homicide numbers.”

This Arrowhead Was Made from a Meteorite 3,000 Years Ago – Found in Switzerland in the 1870s…. examined with X-ray tomography and gamma spectrometry recently. Based on the chemical composition, the researchers say it may have been made from a meteorite that fell in Estonia aroud 1500 BCE; a fragment must have reached Switzerland through trade.

Skin cancer screening guidelines can seem confusing – three skin cancer researchers explain when to consider getting checked - Since the early 1990s, the incidence of melanoma has risen dramatically in the U.S. This increase may be due in part to more emphasis on early detection. Despite this, the rate of death per capita from melanoma has remained unchanged over the last 40 years!

Over one million acres of tribal land submerged by dams in the US, research finds - Over the centuries, colonial settlers and the federal government have acquired over two billion acres from Native nations through various policies, including forced removal, allotment, and the reservation system.

Are You Ready to Have an Immersive Experience — With Your Home Yard? – I am gradually reducing the amount of my lawn…a little this first year in the house….more next year…and every year thereafter until there is very little – if any – grass to mow. Our homeowners’ association has ‘rules’ that I am currently following by simply extending flower beds around the house and making beds in the corners of the back yard. Hopefully by the time I want to turn more of the grassy areas to meadow, the project to create a meadow around the neighborhood ponds will be a success…and the ‘rules’ will change.

Rising methane could be a sign that Earth’s climate is part-way through a ‘termination-level transition’ - Since 2006, the amount of heat-trapping methane in Earth’s atmosphere has been rising fast and, unlike the rise in carbon dioxide (CO₂), methane’s recent increase seems to be driven by biological emissions, not the burning of fossil fuels. Natural variability…or the beginning of a great transition in Earth’s climate?

Wildfires and farming activities may be top sources of air pollution linked to increased risk, cases of dementia - Particulate matter air pollution from agriculture and wildfires might be more neurotoxic compared with other sources.

8 Great U.S. National Parks for Birding – Everglades, Hawai’i Volcanoes, Saguaro, Congaree, Channel Islands, Zion, Redwoods, and Yellowstone. I’ve been to 6 out of the 8!

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.

In 2050, over 800 million people globally estimated to be living with back pain: Analysis also dispels common back pain myth -- ScienceDaily – Attributable to occupational factors, smoking and being overweight. More common among older people and women. Current clinical guidelines for back pain treatment and management do not provide specific recommendations for older people. Low back pain continues to be the greatest cause of disability worldwide.

Why Are Some Wolves Black? The Answer Will Surprise You - Cool Green Science – There are more black-colored wolves in the southern Rocky Mountains…more gray coated wolves everywhere else. The black is from dogs that traveled with humans across the Bering Strait around 10,000 years ago, and those genes also make the black-colored wolves more resistant to distemper (which came with the conquistadors to South America).

We now know exactly what happens in nature when we fell forests -- ScienceDaily – When agriculture replaces forestry…a detailed study done in the Azores…substantiates the advise to plant native trees and flowers…stop mowing the lawn!

The viruses that helped to make you human - BBC Future – About 8% of the human genome comes from viruses but, curiously, there is not evidence of new endogenous retroviruses (ERVs) entering the human genome in the last few 1000 years (Koalas are being invaded by koala retrovirus with the viral DNA found in some populations but not others). The most studied human ERV is HERV-W; first described in 1999; genes that are essential for the placenta to form.

Algae in the Andes – Bursts of phytoplankton are not unusual in oceans, seas, gulfs, and canals. Now they are in lakes too….and potentially hazardous.

New Low Cost High Performance Perovskite Solar Cells – It appears that solar cells are on track to get better and better!

Communities should reconsider walking away from curbside recycling, study shows -- ScienceDaily – Maybe the trend of towns and cities across the US cancelling or scaling back recycling programs due to rising costs needs to keep recycling but focus on recycling materials with the greatest market value (newspaper, cardboard, aluminum/steel cans, HDPE/PET plastic bottles) and highest potential for carbon offset.

Does the roar of rocket launches harm wildlife? These scientists seek answers – Launches at Vandenberg have increased from 5-15 rockets per year to 50-100. There are biodiversity hotspots near launch sites in California, Texas, and Florida; the study at Vandenberg is intended to provide more insight about how launches impact wildlife. The study is funded for 3 years but may need a decade to understand some of the impacts.

Remains of Child Mill Workers Examined in Northern England - Archaeology Magazine – A study of 150 remains from a churchyard cemetery…many were young people between the ages of 8 and 20. They were pauper apprentices and their bones showed signs of stunted growth, malnutrition, rickets, and tuberculosis.

Turmeric: here’s how it actually measures up to health claims – Many of the health claims have only been proved in the lab or in animals. There are studies that show that turmeric has a modest benefit for pain compared to a placebo – but the studies are often on small populations and there is a wide variation in the amount of turmeric participants were given. There is not enough research to firmly support any of the claims…although it is a great spice (flavor and color).

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.

A mixture of trees purifies urban air best – Conifers do a better job at gaseous components of pollution…and they do it all year round; this is particularly important since pollution can be at its highest in winter. Broadleaved trees are more efficient at cleaning the air particles, perhaps because of their larger surface area.

Once the Callery pear tree was landscapers’ favorite – now states are banning this invasive species and urging homeowners to cut it down – Back in the 1980s, the neighborhood I lived in organized to plant Branford pears along our streets. The neighborhood I moved to in the mid-1990s had mature Bradford pears; they were knocked down by Hurricane Isabel in 2003 (the trunk of the one in our neighbor’s yard broke close to the ground with a loud crack) and not re-planted. My neighborhood in Missouri was built in the late 1990s and there are some mature trees near the entrance.

Assessing the risk of excess folic acid intake – Too much or too little of a good thing (folic acid) may not be such a good thing.

School choice proposals rarely go before voters – and typically fail when they do – Public schools have been the backbone of American greatness. How do parents make choices to do otherwise? I suspect that sometimes a Charter School that looks great turns out to be something completely opposite because it is so difficult for individuals to gather enough information to evaluate a school. So - why are legislatures keen to support non-public schools?

The East Coast Whale Die-Offs: Unraveling the Causes – There have been headlines on this as a new challenge; this article includes some data collected so far. There have been periodic whale strandings earlier (back in 2016-2017) too. Almost all the carcasses this winter in New York and New Jersey had clear signs of vessel strike and many were juveniles. It appears that the feeding areas for whales have shifted due to warmer water and that shift has put them in areas with more ships (i.e., ports of New York, New Jersey, and Philadelphia).

Mary Wollstonecraft: an introduction to the mother of first-wave feminism – A little history…but not just about feminism. “Liberation from oppression means being able to define ourselves and the direction of our lives. And this requires access to the intellectual resources and knowledge needed to develop independence of mind. This is Wollstonecraft’s most important message, and one that should speak to everyone regardless of gender.”

Cornell Study Finds Solar Panels Help Crops Grow & Crops Help Solar Panels Last Longer – Not all crops can grow under solar panels but enough of them do (like tomatoes and soybeans) that there is no reason for solar panels to reduce farmland!

Global warming is changing Canada’s boreal forest and tundra – It’s complex. In general, as temperatures warm, trees will colonize further north…but not at uniform rates in all regions.

Greater gender equity helps both women and men live longer – The study looked at 156 countries between 2010 and 2021 to assess the gender gap in life expectancy around the globe. The three dimensions included in the study were political, economic, and educational. Of the three, education has the strongest association with longer life expectancy. The study authors summarize: “the evidence demonstrates that enhancing women's representation across multiple sectors contributes to wealthier and, hence, healthier societies for all."

Less Than 1 Percent of People Globally Breathing Safe Levels of Pollution, Study Finds – Focusing on particulate pollution: particulate pollution has fallen in Europe and North America over the past two decades, but risen in sub-Sharan Africa, India, China, Southeast Asia, Australia, New Zealand, Latin America, and the Caribbean. (see Lancet article with maps here).

800-year-old hoard unearthed in northern Germany – The picture of the earrings made me wonder how they were worn…and what stones once were held in the empty enclosures.

Firewood theft: The forests where trees are going missing – Evidently it is happening around the world…maybe caused by increasing heating costs and/or other fuels not available after a disaster or during a war.

Bald Eagles aren’t fledging as many chicks due to avian influenza – Oh no! I had gotten used to seeing bald eagles frequently near where I lived in Maryland. I had assumed that I didn’t see as many in Missouri because I didn’t know where to look – but it could have been that there are fewer birds to see anywhere.

New thought on Chaco Canyon Construction – A demonstration of how the timbers for building the complex structures at Chaco Canyon could have been carried the 60 miles from where the trees grew.

Sustainable process to produce vanillin from lignin makes further progress – Making the popular flavoring agent from lignin (a waste product from the wood pulping industry) rather a chemical process using petroleum.

Quilts from the Second World War tell the stories of the Canadian women who sewed them – A little Canadian history…the spirit of giving during a stressful time…sending artful warmth. Quilts have always appealed to me because they are functional art. My great-grandmother (in the US) made wedding quilts with/for her 5 daughters in the 1930s and 1940s…and now one of my sisters is talking about quilting being something she plans to do when she retires.

More Than Half Of New US Electricity Generating Capacity In 2023 Will Be Solar – Good! Evidently California and Texas are the states adding the most solar capacity.

Archaeologists Find Elite Residences at Mexico’s Chichén Itzá – Prior to this discovery, experts didn’t know any residential structures! What they found was a complex…two houses and a palace.

Air pollution speeds bone loss from osteoporosis – A study of a diverse cohort of over 160,000 postmenopausal women. The study found that nitrogen oxides are a major contributor to bone damage and that the lumbar spine is one of the most susceptible sites to this damage. This is another reason to improve air quality!

Photography In the National Parks: Capturing Atmospheric Phenomena – Being in the right place…noticing atmospheric phenomenon…and capturing the image. It reminded me of a trip we made back in 2007 to Cumberland State Park in Kentucky where we saw a moonbow; maybe we should go again!

Characteristics of older forests can buffer effects of climate change for some bird species – Results from an 8-year study (2011-18). Forests can provide refugia for some species….our stewardship is important.

Ruby was the first Black child to desegregate her school. This is what she learned – I’m glad she survived and thrived….don’t want any child going through this type of experience in the future. Education is challenging for child without accompanying trauma from the community or institution or bullies.

Should you feed garden birds? – Right now we have 2 bird feeders and baths…with a few plants in the yard that attract birds as well. Over the next few years, I will be planting for the birds – native plants that will support insects the birds need particularly during their breeding season…produce pollen and nectar and seeds to round out their diet.

Earth’s Iconic Waves, observed by Landsat – A 3.5 minute video about places on earth where the waves are significant enough to be visible from satellites…and a little about why those spots produce the types of waves observed.

The sands of Mars are green as well as red, rover Perseverance discovers – The discovery of volcanic rocks on Mars rich with large grains of olivine! I remember going to a green sand beach on the big island of Hawaii – olivine on earth.

Enhanced Geothermal Technology Cracks The 24/7 Energy Code – Maybe a technology that will be as important as wind and solar in our renewable energy portfolio.

What older adults do while they sit affects dementia risk – Passive behaviors like watching TV increased dementia risk-- on the plus side active behaviors while sitting like reading and using computers reduced dementia risk. The study had more than 145,000 participants aged 60 or over with nearly 12 years of follow-up.

Cataracts: we’re working on eye drops to treat them so people don’t need surgery – Glad the research is happening…probably not fast enough to be available when my cataracts will require treatment.

When Told About Flood Risk, Homebuyers Shun Vulnerable Homes, Study Finds – I shouldn’t be a surprise that people don’t want to buy properties that flood….and there are a lot of expensive coastal properties that have an increasing flood risk.

Aging clocks aim to predict how long you’ll live – Really? The value of the various aging clocks is still TBD.

Wildflower Fungi – This post was from the Master Naturalist group in Springfield MO. I am paying more attention now that I am moving to the area.

Deforestation drives climate change that harms remaining forest – Deforestation causes changes in a regions air temperature and precipitation…instigating changes in the whole region rather than just the part where the forest was removed.

Scientists Identify 50,000th Spider Species on Earth—but Thousands More Are Waiting to Be Discovered – It’s humbling to realize that there is so much about our world that we don’t know….have not discovered.

Amid Hopes and Fears, a plastic boom in Appalachia is on hold – Another sad trend in Appalachia…still hitching their future to fossil fuels. The jobs look good but the long-term jobs are few and the market for their products is not a positive one. Everyone wants to reduce single use plastics as much as possible.

Study suggests tree-filled spaces are more favorable to child development than paved or grassy surfaces – Playgrounds need more trees!

NASA and USGS Launch Landsat 9 – The first Landsat was launched in July 1972 – the year my husband and I graduated from high school.

A new solid-state battery surprises the researchers who created it – Solid state electrolyte and an all-silicon anode – faster charge rates at room to low temperatures. There is a lot of battery research going on now …coming up with batteries that will help achieve the grid storage and transportation needs of the future.

Young People Are Anxious About Climate Change And Say Governments Are Failing Them – It’s not just young people that have this anxiety. Everyone I know has climate change anxiety….and say governments are failing us all.

Wind energy can deliver vital slash to global warming – It’s a component of the technology we need….it can’t solve everything alone but we have it ready to deploy now – and should just do it as quickly as we can. And it’s cheaper than using fossil fuels!

Young female black bears in Asheville, North Carolina, are big, have cubs early – More research needed…it’s still not known what is causing them to be so much bigger and mature early…or if the population is increasing or not. It is clear that there are quite a few bears and lots of opportunity for interactions between people and bears – many not healthy for the bears.

The alarming risks of mixing common drugs – It is a problem that is acute in most elderly patients with good medical care. Their various doctors have gradually built up the medications…and the regime to take them all appropriately becomes daunting. Hopefully it will become best practice to constantly review and minimize drugs that are prescribed.

Hummingbirds can smell their way out of danger – I was thinking a lot about hummingbirds this past week after my success photographing one at Brookside Gardens.

Praying Mantis – I see these more frequently in the fall…but not every fall. There are so many mantis egg cases, there should be plenty to see; I need to improve my observation skills.

How much energy do we need to achieve a decent life for all? – The most important take away from this study: “energy for eradicating poverty does not pose a threat for mitigating climate change.” That is good news

The lost generation of ancient trees – The ancients are dying….and there are not enough trees old enough to replace them. There are various ways being tried to veteranize younger trees so they can play the role of ancient trees in ecosystems.

Fall Armyworms are Attacking Lawns and Crops on an ‘Unprecedented’ Scale – Hmmm…maybe this is a prompt to reduce or eliminate the grassy portion of the yard.

Mammoth Cave National Park: The World's Longest Cave Is Longer Than Before - 8 more miles mapped bringing the total to 420 miles!

Hand pollination of crops is of major importance – I was surprised that hand pollination is already used for important crops like apple, palm oil and cocoa.

Painless paper patch test for glucose levels uses microneedles -- ScienceDaily – A technology (microneedles) looking for a problem to solve (prediabetic testing). So far - it’s just a lab exercise but they were readying for human trials. They didn’t explain why it was focused on pre-diabetic testing and not for diabetics.

Top 25 birds of the week: Non-migratory – Beautiful birds…always a visual treat.

These are some of America’s most beautiful urban parks – The one in Greenville, SC looked very non-urban!

Doing Something About Global Warming Is Cheaper Than Doing Nothing – I selected a series of gleaning for this week that are focused on various aspects of climate change – with a mix of perspectives. This is the first one. For the pure capitalists…this one makes the argument for action in their terms. This first article came out back in September…so it is a little dated…but still makes some good points.

The daring plan to save the Arctic ice with glass - BBC Future – Do we want to consider Geoengineering?

40% of O'ahu, Hawai'i beaches could be lost by mid-century -- ScienceDaily – Sea level rise…and our response to it.

6 Graphics Explain The Climate Feedback Loop Fueling US Fires – Some good graphics about the fires on the west coast of the US. In recent days, fires in Colorado have been added to the news. At a time when forests sequestration of carbon is important for the health of the planet….the fires are reversing that benefit.

Natural Debate: Do Forests Grow Better With Our Help or Without? - Yale E360 – Hurray for natural regeneration – unless the land is too degraded for that to be possible…then our help is needed.

The Best Places for Solar Power If You Want to Clean The US Grid – Where investing in solar power would do the most toward reducing grid emissions…by state.

Unique Activities for Yesterday:

A busy morning. The only extra activity I’d planned yesterday morning was to get my car washed since the dirt road into the CSA is history for the year. The car is cleaner (at least on the outside) than it has been for months! The weather was so great when I got back that I swept the leaves from the driveway, street gutter, and deck onto the yard so that the mower would mulch them when my husband mowed later in the day. When I got back inside – I noticed my husband had called from the vet parking lot saying his battery was too low to start his car (and the vet had resolved the cat’s bleeding claw issue)….so I was off to help that car situation. We managed to get home just in time to cook lunch. The level of activity was greater than any recent morning (months and months of mornings!) …and I felt a little discombobulated! I’ve begun to enjoy the pace of pandemic life!

Gleanings for Week Ending 6/13/2020

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.

Why some older adults remember better than others -- ScienceDaily – The article seems to be more about the technology that enables these studies….hints at findings that may eventually be actionable.

The World’s Forests Are Getting Younger and Shorter, Research Finds - Yale E360 – This article is a little confusing. It says that ‘climate change is altering the age and structure of the world’s forests’….but it’s more than climate change. It’s also land use decisions (like logging , conversion to agriculture, introduction of invasive species) that have changed the forests. I was disappointed in the article although the last sentence seems obvious: “We as a human society are hitting these forests so rapidly with so many different changes that they can’t keep up.” Now the big question is – what are we going to do about it?

Remains of 60 Mammoths Discovered in Mexico | Smart News | Smithsonian Magazine – North of Mexico City.

Photographer Captures ISS Transiting the Sun in First Solar Photo Shoot – A challenge…requiring lots of planning, practice….and then success!

Top 25 birds of the week: LBBs - Wild Bird Revolution – Little brown birds…. they are everywhere.

Ancient Roman Mosaic Floor Unearthed Beneath Italian Vineyard | Smart News | Smithsonian Magazine – Finally returning to a site first discovered in 1922 and making this find within a week of starting excavations. The mosaic floor is well preserved a few meters below the vineyards surface and is thought to date from the 3rd century AD.

The Infant Gut Microbiome and Probiotics that Work | The Scientist Magazine®  - Evidently the infant microbiome has changed in the past 100 years…even among breastfed babies. And maybe that explains some of the immunologic problems in young children. There are indications that the probiotic helps babies nutritionally and immunologically.

Two bacteria allow spittlebugs to thrive on low-nutrient meals -- ScienceDaily – One of the bacteria uses aerobic glycolysis to process glucose to synthesize 7 essential amino acids plus 2 biproducts that the other bacteria uses to create ATP to produce 3 additional essential amino acids. It’s a similar two cell type process used by cancer cells.

An Encounter with Mating Gopher Snakes – Springtime out in nature…. this article from Idaho.

The gilded mummy of Lady Isaious | Egypt at the Manchester Museum – A Graeco-Roman Period mummy from the 1st century CE.

Unique activities for yesterday:

A large Zentangle tile. I printed a page (on card stock) from The genera of the plants of the United States illustrated by figures and analyses from nature by Asa Gray and Isaac Sprague published in 1848 available from Internet Archive.

Then I used the lotus as the ‘string’ for an 8.5x11 Zentangle tile. Like most strings….it mostly vanished. It took me about three days working for short periods of time to finish. Next time I’ll use more colors so that the botanical print ‘string’ remains more visible.

Filling a Day of Social Distancing - 5/8/2020 - Gleanings

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Coloring a flower picture. I found a wonderful book on Internet Archive – Flower Designs by Marcia Bradford. It is printed one flower per page with light lines. They were originally intended for watercolors. I selected the one that looks like a California Poppy first (saving the morning glory for another day); there are 18 flower pages to pick from!

I saved the page from the book as a jpeg then printed it on manila cardstock. I used a paper cutter to make ‘tiles’ (so that it would be a mosaic rather than one 8.5x11 inch page). I like the colored result. Tomorrow I’ll fill in some of the blank area with ‘tangles’!

Bringing in more iris stems. We had a freeze watch for overnight, so I cut two more iris stems yesterday. The others are not far enough along to bloom, so I left them outside and hoped they would survive the frost. I took the vase outside so that I could put the new stems into water right away with the stem I’d cut previously.

Unfortunately, I bumped the flower on the way back into the house so now the flower is in its own small water glass.

While I was out, I also cut more mint to use in my smoothie with the chocolate protein powder. It tasted so good last time that I’ve added the combination to my smoothie rotation. Hopefully, the temperature will not get down low enough overnight to kill the mint.

And now – the Gleanings for this week

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.

One little Chipmunk on a Mission! – Pic for Today – Chipmunks are such fun to watch. We have had then periodically around our house but not all the time. They seem to like our front flower beds and porch when they are around. Squirrels are the constant in our neighborhood.

New PMEL Science at Work Video: How tiny particles affect air quality and climate | NOAA Pacific Marine Environmental Laboratory (PMEL) – The video as just under 4 minutes…. explaining how we learn about aerosol particles (important because the particles can impact health).

Image of the Day: Ancient Dental Enamel | The Scientist Magazine® - Quite a lot can be derived from protein sequence analysis these days.

Top 25 birds of the week: Endemic Birds - Wild Bird Revolution – Some birds native only to a certain place.

City of Houston Surprises: 100% Renewable Electricity — $65 Million in Savings in 7 Years | CleanTechnica – The city is planning to power all municipal operations with renewable energy! Also included in the program – the provider will help city employees purchase discounted renewable energy.

Organic food growers see surge in demand during pandemic - UPI.com – Glad the organic farmers are thriving. So far- I’ve been able to get organic produce in my grocery deliveries. My local Community Supported Agriculture farm will begin in June.

Understanding deer damage is crucial when planting new forests -- ScienceDaily – UK research on an issue we deal with in the US too.

Frozen, fresh or canned food: What’s more nutritious? - BBC Future – A little update. The article confirmed what I already knew…it’s good to know I don’t need to reset my thinking.

Analysis of Pompeii's Garbage Suggests the Ancient Romans Recycled, too | Smart News | Smithsonian Magazine – Evidently garbage was piled at city walls and sorted for reuse. They lived much closer to their garbage.

Wildflower Watching as a Source of Solace and Diversion – This is the time of year to find wildflowers. I am always surprised at how amazing even the tiny ones look when I can get close enough to photograph them.

Gleanings of the Week Ending March 14, 2020

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.  

Shrikes: Meet the Bird That Impales Prey on Spikes – The bird creates its “pantry” on barbed wire…other spikey objects. Gruesome…but it’s an adaptation that works for the bird.

The color of your clothing can impact wildlife - ScienceDaily – For water anoles – orange is better than green if you want to see the lizards!

We're Destroying Virgin Forests for Toilet Paper -- What Are the Alternatives? | CleanTechnica – Not good! We in the US are the biggest users…change is hard.

Why Clouds Are the Key to New Troubling Projections on Warming - Yale E360 – Fewer clouds as the planet warms? If so, we’ll heat up more because more solar energy will strike the planet. That’s what the most recent models are predicting and real-world data from satellites suggests that the modelers’ predictions may already be coming true. We’ll have less snow and ice around too to reflect solar energy back into space. It seems like we should make all sky facing manmade surfaces (like roofs) white or lighter colored (unless they are generating energy)…and look for other opportunities to reflect like clouds.

New Research Rewrites the Demise of Easter Island | Smart News | Smithsonian Magazine – There is mounting evidence that Easter Island people created the statues until at least 1750 – after contact with Europeans. And their population has been relatively stable since the 1400s. By the time the British explorer James Cook arrived in 1774 the statues were in ruins. By 1877, just over 100 people remained on Easter Island.

How do woodpeckers avoid brain injury? – Woodpeckers avoid concussions with some adaptions: 1) specialized skull bones, neck muscles, beaks and tongue bones 2) less internal fluid surrounding their brain to limit the motion of the brain during pecking. Interesting…and maybe can help devise ways to protect and heal human brain injuries.

Anti-solar cells: A photovoltaic cell that works at night -- ScienceDaily – Some research…potentially a way to balance solar power over the day-night cycle.

How did the last Neanderthals live? - BBC Future – From caves in Gibraltar….the insight that they were much more like us than we once believed: they exploited seafood and marine mammals (they could swim…hunted dolphins), wooly mammoths, woolly rhinos, ibex, birds (maybe used their feathers…particularly the black ones); they decorated walls and shells; their hyoid bone was like ours (which means they might have had speech like ours); they made tools of bone that were copied by modern humans.

Florida scientists study health effects from exposure to toxic algae - UPI.com – Blue-green algae toxins make people sick (liver damage/disease, skin rashes, headaches, trouble breathing) but does it cause disease when it is absorbed via breathing (i.e. airborne particles) during algae blooms? Fish kills are bad too. It’s good to research the topic but shouldn’t we do everything we can to prevent the blooms in the first place?

Researchers Find Cell-Free Mitochondria Floating in Human Blood | The Scientist Magazine® - Surprise! Now to figure out their function….

Gleanings of the Week Ending October 19, 2019

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.

New report deepens understanding of wind-wildlife interactions -- ScienceDaily – This article overviews the report. The 24 page report is available here. The amount of collaboration between the industry, government, conservation, academic and scientific organizations is significant and ongoing.

Marsh-Billings-Rockefeller National Historical Park Celebrates Forests – Maybe I’ll go to Vermont for this festival next September – if it’s an annual event.

These surreal jarred fish tell an urgent story of extinction – The Royal D. Suttkus Fish Collection – nearly 8 million preserved fish…a window into how 20th century development changed the Southeastern US fish….a record of that destruction.

No bones about it, this protein slows down fracture-healing -- ScienceDaily - Abundance of ApoE may explain why older people have trouble healing broken bones. Turning off ApoE completely causes fat to be deposited in arteries (a cardiovascular problem) so treatment options may involve lowering ApoE for short periods of time.

O Canada! We Like Your Food Guide – Food guides from Canada (and some other countries) … some differences from the US. Canada merges ‘dairy’ in with protein foods rather than featuring it as an independent group.

Scientists Are Getting Better at Predicting Hurricane Intensity – A new algorithm has been developed to include the complicated physical mechanisms of tropical cyclone dynamics and the way they interact with upper-ocean and atmospheric circulation. It may reduce the error of tropical cyclone prediction within a 24-hour period by 16%. Every little bit of improvement in prediction means better preparations when an intense storm is approaching.

Artworks of the Dark Zone – From caves in Tennessee and Alabama. Artwork incised in mud and inscriptions. A slideshow.

How Penn State is Cutting Greenhouse Emissions in Half – and Saving Money – Kudos to Penn State. I wonder how many other universities are doing similar things.

Empty Meditative Landscapes Visualize the Tranquil Beauty of Silence – A visual treat

Ed Hawkins “Climate Stripes” May be the Most Important Science Image so Far in This Century – Effective visualization of lots of data…becomes information. The next step is action.

Gleanings of the Week Ending September 21, 2019

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.

These Caterpillars Can Detect Color Using Their Skin, Not Their Eyes | Smart News | Smithsonian – A little surprise…but insects probably have a lot of adaptations developed over eons that are challenging to imagine.

Five weird and wonderful ways nature is being harnessed to build a sustainable fashion industry – New dyes from enzymes, ‘leather’ from mushrooms, lacy fabric made from plant roots that grew that way (watch the video), cellulose for fabrics derived from manure!

Aesthetics of skin cancer therapy may vary by treatment type -- ScienceDaily – Hopefully these findings will guide doctors to use the more aesthetic treatments…since they all have about the same recurrence rates a year after treatment.

On the Alabama Coast, the Unluckiest Island in America - Yale E360 – Dauphin Island…when does everyone decide that these places can’t be saved…should not be rebuilt. It’s not something we are dealing with very well as individuals or as a nation.

Deer browsing is not stopping the densification of Eastern US forests -- ScienceDaily – Deer hurt the understory but the canopy is more impacted by the greater density of the big forest trees (because of fire suppression) and that red maples are growing in areas where young oaks, hickories, or pines would have grown previously. But wouldn’t the deer browse young trees? In our area – the forests have also changed quite a lot in the last 20 years with the decline of the hemlocks and now the ashes. This study – done in Pennsylvania – did not comment about those issues.

Top 25 Wild Bird Photographs of the Week: September – These photographs are always worth a look….birds are so beautiful.

North America has lost 3 billion birds – And fresh from looking at the wonder pictures of birds….this sobering news: North America has lost 25% of its bird population and it’s all happened in the last 50 years. More than 90% of the loss is in just a dozen bird families that includes the sparrows, warblers, blackbirds, and finches. Grassland birds have suffered a 53% loss. Potential causes: habitat degradation, urbanization, and the use of toxic pesticides.

Staying at elementary school for longer associated with higher student attainment – My daughter didn’t seem to have a problem transferring from elementary to middle school after 5th grade…but the middle school was next door to the elementary school, and she was doing well in school. The results of this research will have to overcome the school building infrastructure in many areas. Change happens slowly with school systems. So far I haven’t seen a change in start times for high schools even though there are studies that say that early starts are not good for high school students (in our area, they have always started before the elementary and middle schools).

Spotted in Kenya: a baby zebra with polka dots – I hope there is a follow up story on this baby. Will the pattern make it more susceptible to fly bites? Another note from the article: Zebras are accepting of difference…animals with atypical coat patterns fit right into the herd.

Drought Reveals Lost “Spanish Stonehenge” – The Dolmen at Guadalperal has resurfaced from the Valdecanas Reservoir in western Spain due to lower lake levels from dry, hot conditions this year. It has been submerged for 50 years. Hopefully someone will make a good 3D tour of the place.

Gleanings of the Week Ending September 7, 2019

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.

BBC - Future - Is city life really bad for you? – Some additional reasons we need to make changes to cities --- if that is where the bulk of humans will live in the future.

A Field Guide to Commonly Misidentified Mammals – Cool Green Science – How many of these animals can you correctly identify?

Blood vessels turning into bone-like particles -- ScienceDaily – The headline caught my interest…bone-like particles in the blood. Then I noticed that the researcher was from the school where I did my undergraduate work back in the 1970s!

Top 25 Wild Bird Photographs of the Week: Raptors and Migration – Catching up on these weekly posts from National Geographic. I always enjoy them.

BBC - Future - Can you cool a house without air conditioning? – We’ve probably had our last 90 degree plus day for the season at this point….but over the long term, I expect broadening the technologies we use to cool our homes and buildings is going to be important.

Turquoise-Tinted Tarantula Discovered in Sri Lanka | Smart News | Smithsonian – Iridescent color that must startle the spider’s prey (or a predator) --- and a discussion of collecting by scientists.

See a different endangered animal in every U.S. state – The map is easy to explore. The Puritan Tiger Beetle was the one listed for Maryland….not something I had heard of before.

Infographic: How Muscles Age | The Scientist Magazine® - A little muscle anatomy lesson – for young and old.

The Earth's Vegetation Stopped Expanding 20 Years Ago - News | Planetizen – Another indication that climate change is already having a worldwide impact?

Forest-killing bark beetles also might help ecosystem, experts say - UPI.com – It’s distressing to see a forest of dead trees…but maybe it’s an indicator that monoculture forests and fire suppression are not healthy. And then there is climate change in the mix as well. The beetles now survive the winter temperatures in much of their range.
