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.

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.

Water Worker Stumbles Upon 2,500-Year-Old Gold Necklaces in Spain – Celtic gold….from before the Roman Empire ruled the Iberian Peninsula.

Canopy gaps help eastern hemlock outlast invasive insect – Hemlock wooly adelgid killed most of the hemlocks in the part of Maryland where I lived previously. Perhaps part of the reason so many died was that they were in forests where there were too few gaps in the canopy around them.

Germany to Surpass 50 Percent Renewable Power This Year – Good milestone but evidently Germany is still not on pace to reach its goal of 80 percent renewable power by 2030.

The surprising origin of a deadly hospital infection - The burden of C. diff infection may be less a matter of hospital transmission and more a result of characteristics associated with the patients themselves (i.e. patients that are already colonized with C. diff were at greater risk to transition to infection). However, it is still unknown what triggers the transition from C. diff hanging out in the gut to the organism causing diarrhea and the other complications resulting from infection.

Meet the Bison: North America’s Most Famous Mammal – Lots of info on bison…their history of almost being hunted to extinction.

The secret world of rhododendrons: a plant more ancient than the Himalayas that inspired fables and stories around the world - There are around 1000 species in total, and modern DNA-based work confirms that all “azaleas” are in fact species of rhododendron.

A Sign of Things to Come? After Last Ice Age, Europe Cooled as the Planet Warmed - More than 8,000 years ago, as the planet thawed following the end of the last ice age, Northern Europe abruptly cooled. New research reveals that Arctic ice melt weakened a critical ocean current, leaving Europe in the cold, a finding with important implications for future climate change.

Fiber from crustaceans, insects, mushrooms promotes digestion – Chitin (from insect exoskeletons and mushrooms) activates the immune system and benefits metabolism. Insects are not on my menu….but I could eat mushrooms more frequently. The researchers plan to follow up to determine whether chitin could be added to human diets to help control obesity.

Review of over 70 years of menopause science highlights research gaps and calls for individualized treatment - Less than 15% of women receive effective treatment for their symptoms. Socio-economic factors such as lower quality of life and the potential negative impact of menopausal symptoms on a woman's work performance aren't often acknowledged. Therapy should be individualized depending on age and health risks, recognizing that health risks may increase with age.

California and Florida grew quickly on the promise of perfect climates in the 1900s – today, they lead the country in climate change risks - In California, home owners now face dangerous heat waves, extended droughts that threaten the water supply, and uncontrollable wildfires. In Florida, sea level rise is worsening the risks of high-tide flooding and storm surge from hurricanes, in addition to turning up the thermostat on already humid heat. Global warming has put both Florida and California at the top of the list of states most at risk from climate change. These futures bring into question how historic visions of economic growth and the sun-kissed good life that California and Florida have promised can be reconciled with climates that are no longer always genial or sustainable.

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.

After a shaky start, airborne wind energy is slowing taking off – Another way electricity might be generated in the future…but still a lot of work to be done.

Crews working to cull 600-900 bison from Yellowstone’s herds – I guess this happens every year at this time…even though in the rationale to cap the Yellowstone herd at 5,000 animals involved the mistaken idea that the bison were spreading brucellosis to cattle herds (research has shown that it is elk that spread the disease).

What damaged that tree? Probably not what you think – I guessed correctly….but only because I had seen something similar on a tree during a naturalist led hike…and they had identified the animal that make the marks!

The mystery of Mexico’s vanishing stream oaks – A great piece of trivia: Mexico has more species of oak tree than any other country! The article is about trying to save one of those species.

Three in four people worldwide support a ban on single-use plastic – Wide support…but no clear path on how we can do it. As a consumer – I try to avoid single use plastics, but some products don’t come in any other kind of packaging!

Seeing ‘green’ can ease confusion, anger in navigating hospitals – It’s not just hospitals that could use more natural views and ‘green.’

Top 25 birds of the week: waterbirds and seabirds – Terns, scoters, herons, gulls, cormorants, ducks, spoonbills, kingfishers, sandpipers, plovers, grebes…enjoy the photographs!

Warming temperatures are turning Antarctica green – Another indicator of how fast the Earth is changing….and that even Antarctica is not immune.

Drought depletes a reservoir in Spain, revealing a ghost village – The dam was installed in 1992 so this is not an old reservoir. The US is having similar drought related problems with Lake Mead behind Hoover Dam installed in 1935.

After 25 years at sea, shipwrecked Lego pieces are still washing ashore on beaches in England – Plastic is very durable…the pictures of the small Lego pieces still look pristine. Some of the pieces sank…some floated…they are all moving around and, very slowly, breaking down either in the ocean or on the beaches of Cornwall.

Top 25 birds of the week: Predatory Birds – Starting out the gleanings list this week with birds…and photography.

The ingenious living bridges of India – Maybe other kinds of structures could be grown instead of built. The bridges look like Ewok structures from Star Wars movies!

Watch Over 150 Bison Weave Through Traffic in Yellowstone as Winter Migration Begins – I remember bison on the roadway during the early summer we went to South Dakota more than 20 years ago. It is an awesome experience to see them – using the car as a blind.

Chocolate: From Witchcraft to Miracle Worker in Early Modern Europe – A little history of chocolate as it was introduced to Spain.

More than ceremonial, ancient Chaco Canyon was home, new study says – I’ve only visited Chaco Canyon once…want to go again.

Richly Adorned Egyptian Tomb Could Rewrite the History of Mummification – Maybe….there is still testing to be done before the mummy in the tomb is confirmed to be old enough to be the man the tomb was built to hold.

Surprising Tales of Toxic Animals – I enjoyed the historical perspective in the information about several of the animals.

A diet of essential amino acids could keep dementia at bay – I wonder how long it will be before the patent for the supplement is awarded…..and it is released as a supplement. Hopefully there will be testing him humans beforehand.

This New Installation Pulled 20,000 Pounds of Plastic From the Great Pacific Garbage Patch – We need to stop producing messes….and clean up the ones we’ve already created. This is one attempt to start a massive cleanup of plastics that are in our oceans.

Bone-loss discovery points to new treatment for osteoporosis – I am glad there is ongoing research on this issue since the existing treatments don’t seem to work that well….often have side effects. Hopefully there will be more effective treatments by the time I might need them.

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.

Mapping out rest stops for migrating birds: New metric can help determine when birds fly over a site or stop to refuel or rest -- ScienceDaily – Stopover-to-passage ratio during migration research involves analysis of weather radar data collected since the 1990s…teasing out bird movement from precipitation! Results so far have included some surprises (and there are probably more to come as more of the historical data is processed and the processing becomes more and more sophisticated).

This Crocodile Dad Gives Over 100 of His Kids a Lift – A large species (gharial) with a narrow snout…in India.

Top 25 birds of the week: November 2020 – Birds from around the world….so much beauty in the natural world to see…and try to protect.

Top Solar States Per Capita 2012 vs. 2020 — CleanTechnica Report and US Energy Dept. Aims For Affordable Solar Power – Two posts about solar power. The first article shows the growth since 2012. In states where there wasn’t much growth, I wondered if the utilities in the state or the state government posed barriers to solar power. It seems like the whole country  should be in the mode of getting out of the way or encouraging renewal energy. The second article was about community solar programs from DOE with a mission to ‘bring affordable solar power to every household in the US by 2025’ – a worthy goal but is there enough money in the pipe to do it? This is not a technical problem as much as ‘are we ready to just do it.’

Lullabies in any language relax babies -- ScienceDaily and Baby Bottles Can Shed Millions of Microplastic Particles: Study | The Scientist Magazine® - I’ve been thinking recently about how much things have changed since my daughter was a baby over 30 years ago. I had a lullaby tape (in English) that I played for her in the evenings (although when she got old enough to choose – she wanted soundtracks from Disney movies as often as the lullabies). Now – we’d have digital music playing (rathe than cassette tapes) and maybe there would be lullabies in different languages too. The second article is about some worrisome research and I hope that pediatricians are keeping up and advising parents on best approaches.

When Domestic Birds Go Wild – Chickens, turkeys, ducks, swans, guinea fowl, peacocks, ornamental pheasants, doves and pigeons, emus, and parrots.

Picturing Earth: Astronaut Photography In Focus – A video – just under 70 minutes….with good imagery and discussion.

The return of Europe’s largest beasts - BBC Future – Bison, wolves, and elk…will the agricultural sector of Europe learn to cope with the big herbivores…and a predator?

As Waters Warm, Ocean Heatwaves Are Growing More Severe - Yale E360 – It’s easier for us to notice the heatwaves on land…but the ocean is taking the bulk of the increased heat on the planet and research on marine heatwaves is just beginning. The precise definition of the phenomenon was only proposed in 2016.  

See the World in Detail Thanks to the Close Up Photographer of the Year – Ending the gleanings list this week with some eye candy….enjoy the visual treat.
