Gleanings of the Week Ending May 25, 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.

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.

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.

Humans taking a toll on Yellowstone wildlife - In recent days two black bears have been killed by motorists, an elk and a bison were also hit by vehicles, a newborn elk calf was picked up by motorists concerned for its fate, and a bison calf had to be put down after a visitor tried to help it out of the Lamar River so it could catch up with its mother. I remember that the park had good signage trying to educate people….seems that it isn’t as effective as I assumed it would be.

See the Rare Albino Echidna Spotted in Australia – It’s been named (Raffie) and photographed…evidently still in the wild! A piece of trivia from the article: a baby echidna is a puggle.

Tune in to the Great Salt Lake kestrel cam – Take a look…they hatched on May 17th…and they are growing up fast.

Scientists target human stomach cells for diabetes therapy – Still very much in research phase…but it would certainly improve the lives of a lot of people if it can be developed into a treatment!

This New Device Generates Electricity from Thin Air – Evidently the device can be made from any material that can be punctured with ultra-small holes. Too good to be true….or competitive with established clean energy sources like wind and solar?

Super low-cost smartphone attachment brings blood pressure monitoring to your fingertips – A clip that fits over the phone’s camera and flash…an app. It costs about 80 cents to make but the cost could be as low at 10 cents when manufactured at scale. Evidently it does not need to be calibrated either! I wonder if cuffs will become a thing of the past very quickly!

What we know about the health risks of ultra-processed foods – Research teasing out what exactly about ultra-processed food is bad. I’ve been trying to reduce ultra-processed food…so have been following the advice in this article for at about a year: if you're considering eating a packaged food, read the ingredient list…If you really have no idea what some of those ingredients are, it probably went too far.

You can make carbon dioxide filters with a 3D printer – Printing a hydrogel material that holds carbonic anhydrase (an enzyme that turns carbon dioxide and water into bicarbonate).

Nepal Won’t Move the Mount Everest Base Camp for Now, Despite Risks – Everest’s highest glacier has lost half its mass since the 1990s because of higher temperatures. It may only be a few years before the camp needs to move.

Colombia’s ‘cocaine hippo’ population is even bigger than scientists thought – Wild descendants of the hippos introduced in Columbia by Pablo Escobar….considered the largest invasive animal in the world. There are probably 181-215 of them in Columbia. Several strategies are being tried: contraception administered via dart, castration, exporting the animal to sanctuaries abroad. Culling appears to be the only strategy that can save the biodiversity of Columbia.

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.

Federal flood maps are outdated because of climate change – The challenge of record rainfall events becoming more common and resulting in flooding of places not seen as vulnerable previously.

Hundreds of Monumental “Kites” Spotted in Arabian Desert – Low stone walls that could be enclosures used to guide game for capture/slaughter as early as 8000 BC.

The mystery of the human sacrifices buried in Europe's bogs – Sacrifices or maybe burial for anyone that died mysteriously or unnaturally. I remember being fascinated about the ‘bog bodies’ back in 1970s…buying the book about them by P.V. Glob.

Diet change may make biggest impact on reducing heart risk in people with hypertension – Too bad that the study also found “the availability and affordability of healthy food sources does not easily allow people to follow the DASH diet.” Diets are hard enough to sustain without those extra challenges.

Despite its innocently furry appearance, the puss caterpillar’s sting is brutal – The don’t look vicious….but the hairs have poisonous barbs! There are other caterpillars that also have ‘hairs’ and can deliver painful stings – like the saddleback caterpillars. In general…I avoid handling caterpillars with hairs or bristles!

Cancers in adults under 50 on the rise globally – Earlier detection could account for some of the increase…but it is unlikely to be the sole reason. 8 of the 14 cancers on the rise are related to the digestive system. With those types of cancers, the hypothesis is that the food we eat has changed dramatically and has changed our microbiome composition…and eventual these changes influence disease risk and outcomes. There is still a lot of work to be done but it appears that the drastic rise in early onset cancer began around 1990.

The biggest myths of the teenage brain – Hopefully some of these findings will be factors in decision making for things like high school hours and how to help teenagers better understand themselves.

NREL Study Identifies Opportunities & Challenges of Achieving the U.S. Transformational Goal of 100% Clean Electricity by 2035 – No single solution….having multiple pathways to the goal is probably a good thing.

Arctic lakes are vanishing a century earlier than predicted – Warmer temperatures and more abundant autumn rainfall have caused permafrost around/beneath Arctic lakes to melt…and the lakes shank between 2000 to 2021. The reduction in lakes impacts migratory birds and other wildlife…and human communities in the Arctic.

Fall Foliage Prediction Map – My road trips this fall will offer many opportunities to see fall foliage: 1st week in October in Michigan and Canada, the rest of October around Missouri, then Texas later in October into November.

An effective new treatment for chronic back pain targets the nervous system – A 12-week course of sensorimotor retraining had a positive effect and participants reported improved quality of life one year later (i.e., the relief was lasting). Hopefully the results can be replicated, and the treatment applied to a broader population. There are a lot of people with chronic back pain!

New Study Links Cat Hormones and Gut Microbiomes to Their Social Behavior – Hard to resist a cat story!

Millions of Americans have long COVID. Many of them are no longer working – 4 million full-time equivalent workers out of work because of long COVID (conservative estimate…and that 2.4% of the US working population). There is a push to provide accommodation in the workplace but some of the symptoms are so severe that the person cannot perform the work they did before and maybe too disabled to work at all. No wonder unemployment is low, and some jobs are not finding applicants. Because long COVID is new, it is unclear when, or if, this population will recover enough to re-enter the workforce.

Arche Roach: the great song man, tender and humble, who gave our people voice – An obituary – and history of aboriginal people in Australia over the past century or so.

The promise and danger of Scotland's bog – 80% of the UK’s peatlands are degraded and in deteriorating condition. They store a lot of carbon…motivating restoration efforts. It takes decades to reverse damage done in a short time by a few ditches and a grid of planted saplings.

New molecule may prevent age-related diseases and increase life expectancy and wellness – A group of molecules that enable cells to repair damaged components has been identified….and efficacy was demonstrated in a model organism. The researchers and Hebrew University’s tech transfer company are moving toward pre-clinical studies.

Parts of the moon have stable temperatures fit for humans – Pits and caves that stay roughly 63 degrees Fahrenheit! There are still big challenges for living on the moon: growing food and finding sufficient oxygen, for example

Coming wave of opioid overdoses 'will be worse than it's ever been before' – Fentanyl and carfentanil…combined with methamphetamines and cocaine. The accelerated rates of overdoses are happening everywhere according to a Northwestern Medicine study.

Inside King Tut’s Tomb – New research using the tomb walls to understand the real-world turmoil cause by the death of the young king.

Cocoa shown to reduce blood pressure and arterial stiffness in real-life study – Cocoa flavanols only decrease blood pressure if it is elevated! I enjoy my morning dark chocolate (70+% cocoa) squares…a healthy way to begin the day!

Study recommends six steps to improve our water quality – The study focused on nitrogen pollution.

The cells that give you super-immunity – Memory B cells were first discovered in the 1960s….but there is still a lot we are learning about them as we analyze the data from the COVID-19 pandemic.

Chicken Frenzy: A State Awash in Hog Farms Faces a Poultry Boom – Ugh! Hope North Carolina can figure out how to keep their groundwater and waterways from being polluted. It’s a beautiful state and it saddens me that the intensive hog and poultry production has not developed technology to be friendly to their immediate environment….or any place that is down stream from where they are located.

What’s the Weirdest Animal Courtship? Here Are 4 Candidates – A post that came out on Valentine’s Day.

Heart-disease risk soars after COVID – even with a mild case – Heart disease was already one of the chronic conditions common for a lot of people in later life… now with COVID, the numbers of people are going to increase and the age demographics are skewing younger.

Enhanced forensic test confirms Neolithic fisherman died by drowning – A skeleton from a 5,000-year-old mass grave on the coast of Northern Chile was analyzed with methods used for more recent bones to determine if a person drowned in salt water….and the method worked!

The mysteries of the Ponderosa Pine – The complex relationships between the health of pine forests and: birds, low-severity fire, squirrels, mushrooms, and carbon storage. Forests are complex!

The science of healthy baby sleep - A little history…and the bottom line: there is NOT just one correct approach to how infants should sleep.

Feeling dizzy when you stand up? Simple muscle techniques can effectively manage symptoms of initial orthostatic hypotension – There might be more validation that needs to be done across a wider demographic range…..hope this happens and if it works for a wide range of people so that doctors can immediately start encouraging their patients that have initial orthostatic hypertension (IOH) to use the simple moves before and immediately after they stand up.

Do you know the world weirdest wild pigs? – The post includes 5 of the 18 wild pig species. The only one in North America is the Africa Red River Hog – one was caught in a trap set for feral hog control in Texas (2019); there are evidently Texas game ranches advertising ‘hunts’ for red river hogs which indicates they have been intentionally imported and there has been at least one escapee from one of those ranches! Is there a free-ranging population of African River Hogs reproducing in the wilds of Texas?

From High Above, A New Way of Seeing Our Urban Planet - Yale E360 – Cities – growing and growing. It is mind boggling that urban population has grown from 751 million in 1950 to 4,200 million today.

How changing labs revealed a chemical reaction key to cataract formation: Researchers studying eye lens find a new function for a protein previously thought to be inert -- ScienceDaily – Learning more about the chemistry behind cataract formation….not a treatment yet but better understanding can be the path toward slowing or more targeted treatment of cataracts.

Curious Kids: What are some of the challenges to Mars travel? – A series from The Conversation (in Australia) for children…but interesting to adults too. Kids ask the best questions!

A DOZEN WAYS FAMILIES CAN #OPTOUTSIDE EVERY DAY OF THE YEAR | Children & Nature Network – I’m on a role with the child focused gleanings right now…I would add to the list: find easy access natural spaces (near where you work or live) and visit them as often as possible.

VIDEO: We Hope Your Day Is As Great As This Snow-Loving Panda’s: NPR – Pandas are such a visual treat. This is Bei Bei at the Smithsonian’s National Zoo back in November.  My husband and I missed the snow (we were in New Mexico).

Top 25 Wild Bird Photographs of the Week: Owls – National Geographic Blog – 2018 was my first sighting of barn owls in the wild…awesome.

Ragweed Is on The Move – National Geographic Blog – Not such a big change in the south….in Kansas City the season is prolonged by 23 days. For those people allergic to ragweed…that is a miserable trend.

Some health related posts: Blood pressure: Early treatment advised by US guidelines has no survival benefits -- ScienceDaily and Your heart hates air pollution; portable filters could help -- ScienceDaily – At least the second one was actionable; I now have a portable filter in my bedroom and I think it is reducing my cat allergy – maybe more.

Aerial photos of U.S. national parks from space – I love national parks. Everyone I have been to has had something spectacular to offer. It’s sad that they are all mostly closed (if the bathrooms and visitor centers are not open….they are closed) for this week (partial government shutdown).

How do different light bulbs work? – in C&EN | Compound Interest – Light bulbs have changed a lot during my lifetime. Hopefully now we are on track to have bulbs that are closer to the natural sunlight spectrum so that the light does not cause eye or sleep problems.
