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.

Lessons In Rewilding the Scottish Highlands – Working with nature…increasing biodiversity…reducing monoculture.

Five Shocking Animal Hybrids That Truly Exist in Nature, From Narlugas to Grolar Bears to Coywolves – I’ve heard about a few of these…the pictures were interesting.

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.

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.

What Does a Solar Eclipse on Mars Look Like? New, Breathtaking Images, Caught by NASA’s Perseverance Rover, Give Us an Idea – Images of Phobos passing across the sun’s surface…back on February 8.

Benefits of heat pumps - Nationally, heat pumps would cut residential sector greenhouse gas emissions by 36%-64%!

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.

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.

Climate Change Hurting Water Quality in Rivers Worldwide – Cycles of heavy rainfall and drought are impacting water quality everywhere.

Large amounts of sedentary time linked with higher risk of dementia in older adults, study shows – The average American is sedentary for about 9.5 hours per day! This study found that the risk of dementia begins to rapidly increase after 10 hours spent sedentary each day for people over 60 years old, regardless of how the sedentary time was accumulated.

The puzzling link between air pollution and suicide - More than 700,000 people kill themselves worldwide every year, according to the World Health Organization (WHO). People in the US might be particularly troubled to learn that the suicides here have increased by around 40% over the past two decades….and the nation now has one of the highest rates of wealthy, developed countries. Suicide disproportionately affects men. In the US, around 80% of suicides last year were male. More research is needed to understand the link between air pollution and suicide…but we already know that "tiny, invisible particles of pollution penetrate deep into our lungs, bloodstream and bodies…and are responsible for about one-third of deaths from stroke, chronic respiratory disease, and lung cancer, as well as one quarter of deaths from heart attack."

Archaeologists discover 1,000-year-old mummy in Peru – Long hair still preserved.

Older adults with digestive diseases experience higher rates of loneliness, depression - While life expectancy rates for older Americans are rising, nearly 40% of adults report living with a digestive disease of some kind.

A Chronic Itch: Burrowing Beneath the Skin - Approximately 20% of people suffer from chronic itch, which is medically defined as an itch lasting greater than six weeks. For many, there is no relief. Itch has historically been one of the most overlooked medical symptoms, reflected in the limited available treatment options, most of which have only been discovered recently.

Puffins Are Making a Comeback in Maine - The fifty-year effort that helped puffins rebound in Maine is cause for celebration!

Capturing carbon in savannas: new research examines role of grasses for controlling climate change - Grasses accounted for over half of the soil carbon content across tropical savannas, including soils directly beneath trees. In general, forests primarily store their carbon in the woody trunks and aboveground leaves. In contrast, a significant portion of carbon in grassy ecosystems, such as savannas and grasslands, is stored in the soil, primarily within the extensive root systems of the grasses as well as decaying organic matter. In the context of long-term carbon storage, carbon retained in soils proves to be more reliable, particularly for a vulnerable future marked by warming and increased likelihood of drought and wildfires.

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.

Top 10 Things You Didn’t Know About Distributed Wind Power – Interesting update….and map of annual average wind speed at 30 m. There is so much potential in the center of the country. It would be interesting to see the map extended offshore…but maybe that kind of wind power is only used for wholesale generation rather than distributed wind power.

Dust: how the pursuit of power and profit has turned the world to powder – A review of the book about ‘tiny particles doing terrible things’ created by detonation of nuclear weapons, burning coal, and drying of lakes via irrigation. These tiny particles influence our environment, our health, and our relationship with the world around us. They move around the planet through the air…no one is ‘safe’ from them.

More small airports are being cut off from the air travel network. This is why - A shortage of pilots is partially to blame for major airlines' departure from smaller airports. But changing airline economics means the challenge facing regional airports could become insurmountable. Williamsport PA is the example used in the article.

Health evidence against gas and oil is piling up, as governments turn a blind eye – An Australian perspective…but seems to be applicable to many developed countries, including the US. The methane leaks, water contamination, air pollution…why do we continue to push for gas and oil development rather that pivoting to cleaner (and renewable) sources?

Wyoming and Utah Borderlands – A picture from the International Space Station. I remembered a trip to Utah in 2008 where we drove in the area with a Roadside Geology of Utah book explaining the surface geologic features!

New research explains 'Atlantification' of the Arctic Ocean – Changes coming in the Arctic as a 15-year cycle is ending….and the next phase could result in a faster pace of sea-ice loss.

Stone Case Holding Precious Items Found at Templo Mayor – 15 stone figures found at the temple complex of Tenochtitlán, the capital of the Aztec empire. The figures may have already been 1,000 years old when the Aztecs conquered the Mezcala people that carved them. Also in the case: two rattlesnake-shaped earrings, more than 180 green stone beads, snails, shells, and marine corals.

Workers like it when their employers talk about diversity and inclusion - Research has shown that diversity, equity and inclusion (DEI) initiatives improve creativity, innovation, productivity and organizational performance. One of the reasons DEI initiatives have a positive impact is because workers appreciate them. It’s about making sure everyone feels valued and included.

Supermarkets to the Rescue — Coles Joins Virtual Power Plant – A grocery chain in Australia. Maybe some supermarkets (and other big box stores) in the US will do similar things.

In a Chilean Forest Reserve, the Remarkable Darwin’s Frog Endures – The endangered frog is a smallish leaf mimic with a pointy nose. Males whistle to attract mates. After females lay their eggs on the ground, males swallow them, holding them in their vocal sac as the young metamorphose. Six to eight weeks after hatching, small adults make their exit through the males’ mouths!

Moths With 11-Inch Tongues? - More than 150,000 recognized moth species, though likely another 150,000 or so, give or take, remain undescribed. Many of these species feed birds and bats like some form of “aerial plankton.” Out of the hundreds of caterpillars one moth might produce, few survive to metamorphose into moths. But those that do provide a critical service both as food for nighttime predators and as pollinators, often evolving to be the only ones that can get the job done. Every species of yucca in North America, including the famous Joshua Tree, requires pollination exclusively from yucca moths.

Spooky, stealthy night hunters: revealing the wonderful otherworld of owls - Owls occur across all continents other than Antarctica, spanning an environmental gradient from the freezing Arctic (home of the stunningly beautiful snowy owl, of Harry Potter fame) to the hottest deserts (home of elf owls).

What to know about beech leaf disease, the 'heartbreaking' threat to forests along the East Coast – I remember this entering into Master Naturalist conversations in Maryland before the COVID-19 pandemic…but the cause was a total mystery at that point. It was interesting to get an update. There is still no known way to control or manage disease, but progress has been made; large numbers of foliar nematodes cause the disease (the interfere with chlorophyll production and the trees starve). It hasn’t been that long ago that the Emerald Ash Borer killed almost all the ash trees…before that wooly adelgid killed the Eastern Hemlocks….and earlier, in the mid-1900s, the American Chestnut succumbed to blight. The eastern US forests are very different than they were 100 years ago and the pace of diseases seem to be increasing.

Air Pollution Causes 1 In 6 Human Deaths – Deaths from modern pollution risk factors, which are the unintended consequence of industrialization and urbanization, have risen by 7% since 2015 and by over 66% since 2000. Unfortunately, little real progress against pollution can be identified overall, particularly in the low-income and middle-income countries, where pollution is most severe. It is increasingly clear that pollution is a planetary threat, and that its drivers, its dispersion, and its effects on health transcend local boundaries and demand a global response.

Opioids no more effective than placebo for acute back and neck pain – The study was done in Australia but, hopefully, will lead to stepping away from opioids for back/neck pain. How many became addicted to opioids via doctors writing prescriptions trying to relieve their patient’s back pain?

Antimicrobial Resistance: The Silent Pandemic – The first accounts of antimicrobial resistance (AMR) occurred 2 years after Alexander Fleming warned about it in his 1945 Nobel speech. AMR is now responsible for nearly 700,000 deaths worldwide each year, and it is projected to kill 10 million per year by 2050.

Early Women Were Hunters, Not Just Gatherers – My favorite statement from the article: “Grandmas were the best hunters in the village.”

Overdose deaths involving street xylazine surged years earlier than reported – Drug death data is gathered and analyzed slowly…not so long ago, it appeared that illicit xylazine use was still largely concentrated in the mid-Atlantic states and the Northeast….but it is not showing up in street samples all across the US and surging in the South and West. US drug deaths hit a new record last year with roughly 110,000 fatal overdoses nationwide from fentanyl and increasingly complex street drug cocktails.

U.S. Wind and Solar Overtake Coal for the First Time - In the first five months of 2023, wind and solar produced 252 terawatt-hours, while coal produced 249 terawatt-hours, according to preliminary government figures. The decline in coal is happening faster than anyone anticipated.

Largest-ever atlas of normal breast cells brings unprecedented insights into mammary biology – 12 major cell types, 58 biological states…differences based on ethnicity, age, and the menopause status of healthy women.

Why our voices change with age – Lots of reasons the sounds we make can change. One habit suggested from the article that I am considering: “Singing or reading out loud daily can give the vocal cords sufficient exercise to slow their decline.”

Cedar Breaks Wildflower Festival Starts Friday – Hmmm…maybe I should look for wildflower festivals (along with birding) when I plan our vacations.

Meltwater is hydro-fracking Greenland’s ice sheet through millions of hairline cracks – destabilizing its internal structure - Earth’s remaining ice sheets in Greenland and Antarctica are far more vulnerable to climate warming than models predict, and that the ice sheets may be destabilizing from inside.

Cold is beneficial for healthy aging, at least in animals – Research with nematodes and cultivated human cells. Both carried genes for ALS and Huntington’s disease. Cold actively removed protein clumps…preventing protein aggregation that is pathological for those diseases. The protease activator that caused the change was discovered…and the impact of temperature explored. Interestingly – “human body temperature has steadily declined by 0.03 degrees Celsius per decade since the Industrial Revolution, suggesting a possible link to the progressive increase in human life expectancy over the last 160 years.”

See Colorful Paintings of the Zodiac Signs from an Ancient Egyptian Temple – Ceiling paintings in a Ptolemaic temple…suggesting Greeks brought the zodiac tradition to Egypt.

Vehicle Exhaust Filters Do Not Remove “Ultrafine” Pollution – Aargh! No wonder there are so many yellow and red air quality days in our cities caused by particulates.

What it really takes for Asia to get to net zero – Home to 5 of the 10 largest emitters: China, India, Indonesia, Japan, and South Korea. An article posted ahead of the BBC’s Sustainability Summit in Singapore. "The perception of higher cost for sustainability practices remains," says An (chief sustainability officer of City Developments Limited in Singapore). "But companies are starting to wake up to the fact that achieving climate goals is an "investment, not a cost."

Thread-like pumps can be woven into clothes – My first thought was maybe these will be commonplace in clothes – enabling us to work outdoors even on very hot days.

Sabertooth cat skull newly discovered in Iowa reveals details about this Ice Age predator – Almost as iconic as dinosaurs when it comes to childhood curiosity about extinct animals. One piece of trivia about modern cats: 40% of lion skulls in a study had survived head trauma to hunt another day. One of the ‘sabers’ of the Iowa Sabertooth was broken not that long before it died…might have even caused its death. Prey fights back…the predator does not always ‘win.’

Europe's unique trials in food 'social security' – Two projects: Montpellier, France and Brussels, Belgium. Run by collectives. The idea that quality, nutritious and organic food should be accessible to everyone.  Each citizen receives a monthly allowance enabling them to buy food meeting certain environmental and ethical criteria. The trials are running for 12 months. The big challenge is changing the way society thinks about food.

The Beauty of Bugs – The picture at the beginning of the article jogged my memory – of the necklace made from insect exoskeletons I saw at the Edge of Cedars State Park Museum when I visited Utah in 2013! I posted about it and took a picture back then…and am pleased to learn more about it and the possible implication it might have re the Basketmaker II culture.

Climate change threatens spring wildflowers by speeding up the time when trees leaf out above them – Evidently the trees and wildflowers in eastern North America are the ones getting the most out of sync.

The mystery of Alice in Wonderland syndrome (AIWS) – AIWS (or Todd’s syndrome) affects the way people perceive the world around them and can distort the way they experience their own bodies and the space it occupies. There are 40 types of visual distortions that characteristic of the syndrome. It was formally described as a distinct syndrome in 1955. Up to 30% of adolescents reported mild or transient experiences. Cough medicines and illicit hallucinogenic substances are also known to trigger it.  Sometimes medical conditions like strokes or brain tumors can cause the syndrome as can infections.

Chinook salmon fishing season canceled off coasts of Oregon, California – Dwindling numbers of Chinook salmon in the states’ largest rivers following years of drought.

In Florida, an invasive snail is helping save an endangered bird – We heard about this during a birding trip to central Florida pre-pandemic. It probably is one of the few examples when an invasive species has produced a positive outcome.

Garbage to Guts: The Slow-Churn of Plastic Waste – Lots of microplastics in the world…and they are in our food chain. Ongoing exposure decreases beneficial gut bacteria and increases pathogenic species. A lot more research needs to be done since, right now, we don’t know very much about impacts of microplastics – not just to the overall environment but to our own bodies.

 With Heat from Heat Pumps, US Energy Requirements Could Plummet By 60% - Thinking about heat….and the ‘rejected energy’ (mostly heat) in our current energy consumption. The idea is to use heat pumps to dramatically reduce ‘rejected energy’ in future energy consumption.

Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms – Evidently the December 2021 - January 2022 breeding season for south polar skua, Antarctic petrel, and snow petrel was so disrupted that there were almost no young produced.

Why don’t humans have fur – Interesting…but we really don’t know. The genetic research associated with the question could have practical application for people that need to stimulate hair growth (like after chemotherapy or balding).

2021 Was A Very Good Year for Nesting Wading Birds In The Everglades – Hurray! Some good happening in the Everglades. There are so many stories about the impact of invasive species (like Burmese pythons) that this is welcome news.

Meet the sargassum belt, a 5,000-mile-long snake of seaweed circling Florida - In the open sea, sargassum can soak up carbon dioxide and serve as a critical habitat for fish, crabs, shrimp, turtles, and birds…all positive. But when sargassum gets close to shore it can smother coral reefs, alter the water’s pH…and then onshore it begins to rot within 24 hours releasing irritants like hydrogen sulfide which smells like rotten eggs or manure and can cause respiratory problems. And it often contains significant amounts of arsenic so not a great addition to a compost pile. The mass of sargassum has been increasing since 2011 --- probably in response to elevated nutrients (runoff from fertilizer, burning biomass, increasing wastewater from cities, etc.) we have released into the ocean. Sargassum has come ashore in Yucatan and Key West recently.

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!

Study investigates source of Amazon’s “Dark Earth” – Created intentionally? It is less acidic than surrounding soils…probably from the addition of ash.

New York City Greenery Absorbing All Traffic Emissions on Many Summer Days – There is a lot more greenery that previously thought…looking beyond parks to modest backyards, shrubbery growing in vacant lots, and trees dotting city sidewalks. That’s good for the summer when everything is green and growing….but it also implies that winter air quality is problematic.

‘Stomp’ Performers Hang Up their Garbage Lids – After 3 decades off-Broadway. Watch the video!

Riddle solved: why is Roman concrete so durable? – It wasn’t just volcanic ash that made Roman concrete better…lime clasts play a self-healing role!

Why is every parking lot covered with solar panels? – Evidently Michigan State has done it…hopefully other universities and big box stores do similar projects. 

How the war in Ukraine is killing marine mammals – The dolphins that were washing up on the shore of the Black Sea prior to the war were few and usually had markings suggesting entanglement in fishing gear.  The theory about the increased number appearing now, without marks, is that the dolphins are experiencing acoustic trauma from the increased use of sonar by Russian submarines.

Climate impact labels on sample food menu had strong effect on food selection – A study done by Johns Hopkins. The result indicate that this kind of labelling could promote more sustainable choices….and have positive health benefits as well!

Aerial Photos Capture the Abstract Beauty of Salt Ponds – From a new book….with images and background about these man-made landscapes.

Great Salt Lake will disappear in 5 years without a massive ‘emergency rescue’ – My husband and I visited the lake back in 2008. The pictures in the article are so different that I needed the captions to recognize the place. The lake was already shrinking in 2008 but the shrinking has increased with long term drought and increased population diverting more water that would otherwise flow into the lake. Aside from the ecological collapse if the lake goes dry, the dust from the dry lakebed is kicked up by winds and can damage lungs/exacerbate other respiratory illness. This does not bode well for public health in Salt Lake City.

Painted skulls from Peru’s Chincha Valley analyzed – The red paint on the skulls was not all the same on all the skulls: some have iron-based ochres and others have mercury-based cinnabar….the red paint on one of the skulls was a combination of the two!

H5N1 Bird Flu Detections across the United States (Wild Birds) – A map of US counties where bird flu has been detected in wild birds as reported by the US Department of Agriculture.  It would be great if data could come from the National Wildlife Refuges (reporting through the US Department of the Interior) since they often have concentrations of wildlife and staff that would be monitoring the flocks. I know that there were instances of bird flu – primarily in snow geese - that the Bosque del Apache NWR staff were reacting to when we were there the November before COVID-19 curtailed our travel.

Electric car sales drive toward cleaner air, longer lives – Another reason my next car will be an electric rather than a plug-in-hybrid that I have now. However – this should probably be seen as an offset to the negative impacts on public health that climate change will bring; the air could be cleaner, but it will also be warmer and more turbulent. I am becoming less certain that my lifespan will last into my 90s like it has for my parents.

Living the lava life on Mauna Loa – A satellite image from NASA’s Landsat 9. It shows how close one of the flows came to Hawaii Space Exploration Analog and Simulation (HI-SEAS) project habitat. Fortunately, the most recent mission there concluded in May 2022.

The Dead Sea is dying – The lowest exposed place on Earth…water level dropping 4 feet per year…salt formations and sinkholes.

Beyond cola: the strange flavors of soft drinks – Carbonated drinks were invented by Johann Jacob Schweppe in 1783. They were sold in glass bottles and that were recirculated. Regional delicacies. Everything changed with the advent of plastic bottles in the 1970s. Moxie, state beverage of Maine, continued independently for a long time – bought by Coca-Cola in 2018. Soft drinks had a heyday in the years of Prohibition. Follow the link for the whole article, more soft drink history.

Construction of the world’s largest radio telescope begins – Square Kilometer Array (SKA) – one in Australia and one in South Africa. Construction will be completed by the end of the decade, but observations will begin in 2024.

Flameproofing lithium-ion batteries with salt – Finally….hope this solves the fire problem with lithium-ion batteries and, if so, moves into new battery manufacturing quickly.

The 120-year search for the purpose of T. Rex’s arms – A little history of T. Rex finds…and the various ideas about why the animal had such puny arms.

A new weapon against antibiotic-resistant bacteria – Work to find a new treatment for Klebsiella pneumoniae infections that are resistant to common antibiotics with some strains fatal for 40-50% of infected people. A new strategy: weakening bacteria with an existing drug previously used to treat herpes that alters its surface layer to make it easier for the immune system to kill the bacteria. The idea works in the research model…effectiveness in human beings yet to be confirmed.

The science of why hawks are one of nature’s deadliest hunters – Birds and bats….The birds steer toward a fixed point in the swarm instead of singling out a bat. It’s a good strategy against a gathering of prey!

Best of 2022: Top 50 Photographs from Around the World – The first of the year in summary type articles. I had seen some of these photos before…but not all of them. They are worth a look.

Larger wheat harvest in Ukraine than expected – Based on satellite imagery, 94% of the winter crop was harvested…including 88% in areas not controlled by Ukraine. Some Ukrainian grain made it to global markets…however Russia is reaping the benefit of a significant portion of the harvest.

Medieval woman’s burial in Switzerland yields gold broach – A wealthy burial from a 7th century AD cemetery…excavated prior to construction work. The article didn’t say whether the finds would be going to a museum…or be reburied with the skeleton elsewhere.

More Than 52 Million Birds in the U.S. Are Dead Because of Avian Flu – It began last year in Eastern Canada and has affected flocks in 46 states since then. Wild and domestic birds are impacted…and there is a risk of infections in people too.

Study finds that experiences of daily stress decrease as people age – As we get older, we begin to deal daily stressors better. It’s a positive aspect to aging!

Archaeologists Find 1,900-Year-Old Snacks in Sewers Beneath the Colosseum – The debris from 1,900 years ago: olives, nuts, meats, cherries, grapes, figs, blackberries, and peaches!

Biodiversity unbalanced as ice-free Antarctic areas grow – Non-native species invading Antarctica

Idaho’s Potato Belt – 1/3 of the US potatoes are grown in the Snake River Plain….satellite images from NASA’s Aqua and Landsat 8.

Dam safety: New study indicates probable maximum flood events will significantly increase over next 80 years – This is a paper about 546 dams in Australia. We need to extend this type of analysis around the world…to improve the integrity of critical infrastructure into the future.

What is the right age to get a smartphone? – No set answer or surprises in this article. I was a little disappointed but maybe the answer will always start out with “it depends….”

Air pollution might spur irregular heart rhythms in healthy teens – Air quality is important for everyone…not new news, but this study has supporting data for a segment of the population we generally think are very healthy.

A rapid shift to clean energy would save the world $12 trillion – I wish I was more confident that the people of the world have the will to save the planet (and ourselves).

Seven healthy lifestyles may reduce dementia risk for people with diabetes – Getting all 7 might be hard….but the 5 or 6 out the 7 should be something everyone can do.

Cool and Overlooked Critters of the Sagebrush Sea – Someone commented that they had driven across Kansas once and it was such a long slog that they didn’t want to do it again. This article reminded me that learning to look at unfamiliar places is a challenge…one we should consciously accept!

Daily multivitamin may improve cognition and possibly protect against decline – Easy to do!

Why you need a 'wellbeing wardrobe' – Most of my clothes are over a decade old and some were bought from a thrift store. I wear them until they are worn out and then I turn them into other things, compost them (if they a compostable fiber) or donate them (hoping that they can be sold or recycled). My sister commented that she was saving jeans to make a quilt. There are some items that seem to last longer than they did in the 70s (I remember inexpensive underwear and panty hose that were rarely worn more than a few times). Since I don’t buy many new clothes, I wondered about the demographics of who is buying so much clothing…and then trashing it so quickly.

Older adults with regular activity routines are happier and do better on cognitive tests – Picked up a vocabulary word from this article: zeitgebers – time cues which help set the body’s internal clock and can also assist in creating a stable routine. Some examples of zeitgebers are sunlight, exercise and eating…pets that require certain kinds of attention at about the same time each day.

Why plastic doesn't dry in the dishwasher – A little physics. I’ve noticed that we are using less plastic these days…more ceramic, glass, and metal. The last change was the containers we use for leftovers; I’ve gradually been replacing plastic with glass containers. My popcorn bowl (that I use in the microwave) is still plastic…but that’s about it.

Pregnant women are exposed to cancer-causing chemicals in dishware, hair coloring, plastics, and pesticides, study reveals – Something else for pregnant people to be anxious about. I wish these studies had a stronger component about how to reduce exposure, but it seems that the problematic chemicals are very pervasive.

The U.S. diet is deadly. Here are 7 ideas to get Americans eating healthier – These ideas a geared to making it easier for individuals to make healthier choices. Right now…it seems that the push is toward unhealthy food choices.

Cool planning for a hotter future – Actions we need to take to achieve the ‘late century rapid action’ maps.

Low physical function after age 65 associated with future cardiovascular disease – Individuals were assessed for walking speed, leg strength, and balance….and the scores were more predictive of cardiovascular disease risk than the traditional risk factors that work for middle-aged people (high blood pressure, high cholesterol, smoking or diabetes).

On “Trash” Birds: Rethinking How We Label Common Species – There is no such thing as a ‘trash’ bird or any species. They are all just part of our world!

Can These Lights Make Crosswalks Safer for Pedestrians Distracted by Their Phones? – People shouldn’t be walking while looking at their cell phones more than where they are headed….but they do and maybe Hong Kong is ahead of us in developing a solution to reduce tragedies.

Is Breadfruit the Climate Change-Proof Food of the Future? – Not a food I know anything about…it’s not in our grocery stores yet. I looked at some recipes and it seems like it would be a versatile addition to our diet.

Archaeologists Call on UNESCO to Protect the Hagia Sophia – It’s sad when pieces of architectural history are not maintained. Hopefully this call will help organize what is needed to preserve Hagia Sophia.

Heat waves + air pollution can be a deadly combination: The health risk together is worse than either alone – There are ways to stay safe…but it is not possible for everyone all the time. We need to address the underlying issues for the health of everyone. Often – addressing air pollution also is step in a good direction of climate change as well.

Zion National Park, Utah – A view of the park from the International Space Station. A piece of trivia from the post: Cyanobacterial blooms are a threat to hikers and wildlife – exacerbated by intense summer heat.

Air pollution, including during wildfires, shows ill effects in children -So many questions popped into my mind as I read this article: Does keeping children indoors with modern air conditioning/heating filtered air help? Further air purification required? The children in the study were 9-11 years old; are some of the markers also indicators of stress they may have developed knowing there were wildfires?

Neolithic Watermelons may have been valued for their seeds – Snacks! And now most watermelons we buy in stores doen’t have seeds at all!

Nahuku Lava Tube in Hawai’i Volcanoes National Park Closed to study its stability – Also known as Thurston Lava Tube. I walked through it when we were in Hawaii several years ago.

Vitamin K prevents cell death: New function for a long-known molecule – Important for blood clotting….but new research shows it is also a potent antioxidant that ameliorates cellular iron’s role in cell death (ferroptosis).

Antarctica’s ‘Doomsday Glacier’ melting at fastest rate in 5,500 years – Thwaites Glacier (nicknamed the Doomsday Glacier…Florida-sized) and Pine Island Glacier were studied. The ice shelf holding the Thwaites Glacier could collapse withing 3-5 years.

Finding mini frogs: these aren’t babies, they’re just little – And they hatch as frogs…no tadpole stage. They live in leaf litter…humid and moist but not near water.

New safe-sleep guidelines aim to reduce infant deaths – New guidelines have been coming out from time to time at least since my daughter was born over 30 years ago. When she was a baby, the recommendation was for babies to sleep on their tummy…very different from these current guidelines.

One in 500 men carry extra sex chromosome, putting them at higher risk of several common diseases – A surprising result…most of the men were unaware they carried an extra X or Y chromosome. Those that are XXY had higher chances of reproductive problems. Both XXY and XYY individuals has higher risks of type 2 diabetes, deep venous thrombosis, pulmonary embolism, and chronic obstructive pulmonary disease.
