How a Soviet swamp rat scheme for Azerbaijan went horribly wrong – Nutria introduced in the 1930s…..destroying every wetland in Azerbaijan today.

Light Pollution May Be Keeping Honey Bees Up at Night - On hot nights honey bees will sleep outside and slept less/more fitfully if there is artificial light…which could undermine the health of the colony.

The next massive volcano eruption will cause climate chaos — and we are unprepared – The history of large eruptions and what we can determine about the aftermath…though provoking on what it would be like if a massive eruption happened in the modern world.

Carbon recycling instead of plastic trash – Using iron electrocatalysis and producing green hydrogen as a biproduct…can be powered by solar panels. I hope this can be commercialized near term. We are overwhelming our world with plastic trash!

CT Scans Unlock Secrets of Mummified Individuals at Field Museum – Respect for the ancient dead…but still studying their bodies.

How do countries measure immigration, and how accurate is this data? - Three types of migrants who don’t have a legal immigration status. First, those who cross borders without the right legal permissions. Second, those who enter a country legally but stay after their visa or permission expires. Third, some migrants have legal permission to stay but work in violation of employment restrictions. Most high-income nations have a small minority of irregular immigrants in their immigrant population; the exception is the United States which estimates 22% of their immigrants are irregular.

Riding The Rails on Amtrak's Cardinal Line Through New River Gorge – Maybe a relaxing way to see the National Park and Preserve…thinking about next fall.

Mother Tiger Teaching Cub How to Fight Wins Nature’s Best Photo Awards – Great pictures….but Patricia Homonylo’s video is the most thought provoking….the one that is a call to action.

Geologists rewrite textbooks with new insights from the bottom of the Grand Canyon - From the Tonto Group's 500-meter-thick strata, we're learning about sea-level rise and the effects of catastrophic tropical storms -- probably more powerful than today's devastating hurricanes -- during a period of very hot temperatures when the Earth was ice-free.

Quantifying How Urban Trees Cool Cities - The authors of a new study estimate that the city of Baltimore could reduce land surface temperatures by 0.23°C if they increased tree canopy by 1%. To achieve 1.5°C of cooling, they would need to increase tree canopy cover by 6.39%.

A new era of treating neurological diseases at the blood-brain-immune interface – Investigating the connection of neurological diseases and a toxic immune reaction caused by blood that leaks into the brain….in particular, how fibrid (a blood protein) is responsible for setting of this detrimental cascade.

Antifungal resistance is not getting nearly as much attention as antibiotic resistance – yet the risks to global health are just as serious – Just as with antibiotics for farm animals, tons of fungicides are used annually to protect crops, of which some work the same way as antifungals used in humans. And just as bacterial resistance develops…fungi develop resistance too. Combating drug-resistant fungal infections is a complex problem. An important factor is that diagnoses of infections are often delayed – if they are even diagnosed at all. Simple tests for fungal infections are rarely available.

Nikon Small World Contest Celebrates 50 Years of Photographic Excellence Under the Microscope – Great images….the natural world that we can see only with assistance…an art form too.

So Last Season: The Environmental Impact of Fast Fashion and Textile Waste Exports - The last ten years have seen a dramatic increase in the production of single-wear garments—which has contributed to an excess of textile waste and consequent health impacts for the individuals who work in the textile manufacturing industry. Every aspect of the creation of fast fashion garments is unsustainable, from the creation of plastic-derived textiles to the construction of pieces by underpaid and overworked exploited laborers. Up to half of American textile waste is shipped to nations overseas. Adopting more sustainable wardrobe practices not only helps us move away from fast fashion, but also significantly lowers our individual carbon footprints and waste production.

Plastic pollution harms - Nano- and microplastic particles (NMP) are increasingly polluting urban and rural landscapes, where bees and other beneficial insects encounter them… it can damage their organs and cause changes in their behavior, preventing them from properly performing ecosystem services such as pollination and pest control.

British Ecological Society Photo Contest Celebrates the Breadth and Beauty of the World’s Biodiversity – I liked the variety of selections in this photo contest.

Introducing Six Steps to Calm: Our science-backed, stress-busting email course – From BBC…I subscribed…plan to take the course!

Your diet can change your immune system — here’s how - There is still much more work to do to unpick the effects of specific diets on the immune systems of those with different health conditions. However, a growing group of immunologists are optimistic that the mechanistic insights they are uncovering are the first steps towards personalized diets for a range of medical conditions.

US air pollution monitoring network has gaps in coverage - Most of the harmful effects from outdoor air pollution in the U.S. are linked to inhalation of fine particulate matter (PM). These suspended particles, like soot or liquid aerosol droplets, are smaller than 2.5 micrometers in diameter, garnering the designation PM2.5. In February 2024, to better protect Americans from health burdens caused by inhaling particles, the EPA adopted a more stringent standard for PM2.5. The EPA tracks compliance with air pollution standards through a network of about 1,000 costly and highly accurate monitoring stations placed in cities and towns nationwide. People of color and people with low socioeconomic status living in the U.S have fewer monitoring stations than other areas to measure air pollutants, meaning they may not be fully protected by the tighter air pollution standards.

Researchers Parse the Future of Plankton in an Ever-Warmer World - Climate change is hitting our oceans hard, making them warmer and more acidic, while radically altering currents. The outlook for plankton is mixed. As the planet warms, the diversity of the menagerie in many spots is increasing. But certain species are losing out, including big juicy plankton thought to be important for food webs and carbon sequestration. And, in the long term, plankton numbers may plummet as climate change starves them of nutrients. Meanwhile research continues: which plankton species are where but also exactly when, since shifts in bloom timing can also have big knock-on effects for fisheries. And the viruses that attack plankton seem to be on the rise as waters warm — another factor with as-yet unknown consequences.

Our Missouri Yard – September/October 2024

The chives have flowered and the seeds are almost mature. I savor these plants at the edges of some of my back yard beds since they are descendants of my mother’s plants; I harvested the seeds from her garden several years ago and will be enjoying them in my garden and in meals for as long as I live in this house.

The poke weed that I didn’t pull up is being eating by something. Maybe I should leave more of it for the insects.

There is a plant blooming in one of the areas I’ve not been mowing…letting the violets grow into the grass. I think it is sweet everlasting – which is native. Maybe I’ll collect the seeds and plant it elsewhere too.

I’ve harvested some of the American Spikenard seeds and planted them in a shady area where they might grow next spring. I would like to establish more of this plant in my yard. It dies back each winter but comes back from the root the following year getting bigger each year.

The shortleaf pine has dropped most of its mature cones but there are still a few in the tree and the terminal buds are a great color contrast to the needles….good photo opportunities!

I bought 4 native shrubs and small trees

And got them planted in my back yard the day after I bought them:

Spicebush – Lindera benzoi

Ozark Witch Hazel – Hamamelis vernalis

Buttonbush – Cephalanthus occidentalis

American Beautyberry – Callicarpa American

Digging the holes for these small plants was harder than I expected – a lot of small rocks and some plastic mesh that is a few inches under the soil surface (the previous owner had the yard sodded and they must have put the mesh down before they put the sod…I am chagrined that there is a plastic pollutant under most of my yard but can’t do anything about it).  

I’ll save the fall foliage pictures for another post!

The ancient practice of 'good fire' is reviving Nebraska's birds, bears and berries - In its original shape, the once wide, but relatively shallow Platte River provided an open space for the (sandhill) cranes to roost, while also keeping an eye on predators. These four-to-five-foot tall birds with wingspans of six-to-seven feet found abundant plants and insects to eat on the Nebraskan prairies. Lightning strikes brought occasional wildfires, which cleared out dead material and refreshed native plant life. Fire suppression is not always a good thing…

Giant Slab of Bog Butter Recovered in Ireland – Nearly 50 pounds! It is being analyzed by the National Museum of Ireland. It would be interesting to know how long it had been in the bog.

How Agroforestry Could Help Revitalize America’s Corn Belt – 8,200 hazelnut saplings growing with flocks of chickens in narrow grass paddocks between the rows of fledgling trees…. By combining food-bearing trees and shrubs with poultry production it is an example of agroforestry — an ancient practice that intertwines annual and perennial agriculture. Other forms include alley cropping, in which annual crops including grains, legumes, and vegetables grow between rows of food-bearing trees, and silvopasture, which features cattle munching grass between the rows. An acre of land under agroforestry can sequester five metric tons of CO2 annually, versus one ton for an acre of corn or soybeans. As the region’s vast corn and soybean operations continue hemorrhaging soil and fouling water and climate change proceeds apace, they may find themselves looking for new directions sooner than later.

Humans Pollute the Environment With 57 Million Tons of Plastic Each Year - Uncollected waste is the biggest source of plastic pollution, with at least 1.2 billion people living without waste collection services forced to ‘self-manage’ waste, often by dumping it on land, in rivers, or burning it in open fires. This “self-managed” plastic waste makes up more than two-thirds of the modeled plastic pollution. The study also calculated the largest contributors to plastic pollution in the world: India is in first place, producing 10.2 million tons a year; Nigeria is in second; Indonesia is in third; and China—which had been ranked in first place according to other models—instead comes in fourth. The U.S. ranks 90th, with more than 52,500 tons of plastic pollution produced annually.

One of world's fastest ocean currents is remarkably stable - There is growing scientific and public interest in the global Atlantic Meridional Overturning Circulation, or AMOC, a three-dimensional system of ocean currents that act as a "conveyer belt" to distribute heat, salt, nutrients, and carbon dioxide across the world's oceans. This study found that Florida Current, the beginning of the Gulf Stream system and a key component of the AMOC, has remained stable for the past four decades. Understanding the state of the Florida Current is very important for developing coastal sea level forecast systems, assessing local weather and ecosystem and societal impacts.

Growth of Solar Continues to Defy Predictions - The world is set to install a third more solar capacity this year than it did in 2023, surpassing forecasts by both industry experts and independent analysts. China is driving the bulk of the growth. Through May, India installed more solar capacity than it did in the whole of last year, and in the U.S., new tax breaks are giving the industry a significant boost. Solar manufacturing has jumped fourfold since the passage of the Inflation Reduction Act in 2022.

Birds Form Surprising Relationships with Other Avian Species During Migration - The researchers found that songbirds tended to show up together rather than avoid each other. American redstarts and magnolia warblers reliably appeared together in the researchers’ nets in spring and fall. The same thing happened with ruby-crowned kinglets and white-throated sparrows. The presence of other birds with similar foraging behavior or similar food preferences may signal to newcomers where the good habitat is, helping them refuel more quickly.

Residents in San Joaquin Valley breathe chemical pesticides - A new study found 22% of adults and 10% of children who participated in an air-quality study in California's San Joaquin Valley were breathing detectable levels of pesticides. Participants in this study served as citizen scientists, going about their normal days while wearing the backpacks to collect the samples.

Creative ways communities are reducing food waste – Returning oyster shells to the water in Alabama, collecting food waste for composting in almond orchards in California, gleaning fruit at the end of the season to supply the needy in New Hampshire-Massachusetts, and using underused land to grow free food in Washington.

Only Two US Metro Areas Are Affordable for Homebuyers - Before the Covid-19 pandemic, 20 U.S. states were considered affordable home-buying markets for most households. Today, just two metro areas remain ‘affordable’ by that definition issued by the National Association of Realtors — and no entire states fit the bill. The two metro areas are Youngstown and Akron, Ohio. Home prices have increased by 47% nationwide just since 2020, according to a June report by the Harvard Joint Center for Housing Studies. A major factor is that there aren’t many homes for sale.

Life in a heat dome: The American West is figuring out how to keep cool – Summer in US cities…strategies to mitigate the hotter temperatures caused by climate change.

Statins for heart disease prevention could be recommended for far fewer Americans if new risk equation is adopted – Not a lot of details in this article although I have suspected for some time that statins were being over-prescribed.

10 States Where the Gas Tax Is Highest – This post prompted me to compare gas taxes in the states I drive through to on my frequent road trips to Dallas (Missouri, Oklahoma, and Texas)…and the decision to always buy the tank of gas required in each direction in Oklahoma!

Creating a throw-away culture: How companies ingrained plastics in modern life – Aargh! Despite growing public pressure, companies increased their use of new plastic by 11% between 2018 and 2022!

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

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

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

Rock Art Found in This Saudi Arabian Cave Offers ‘Rare Glimpse’ Into Ancient Human Life – Sheep, ibex, and goats on the walls of a lava tube.

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

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

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

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

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

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

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

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

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

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

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

Then and Now: Groceries

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

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

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

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

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

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

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

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

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

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

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

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

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.

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.

Scientists found hundreds of toxic chemicals in recycled plastics - More than 13,000 chemicals used in plastics with 25% classified as hazardous. Numerous studies show that hazardous chemicals can accumulate even in relatively close-loop plastic recycling systems. We need to rapidly phase-out plastic chemicals that can cause harm to human health and the environment.

Giant Sequoias Are in Big Trouble. How Best to Save Them? - Giant sequoias are, by volume, the largest trees in the world, indigenous only to California. Reaching heights of 300 feet, they occur in 80 groves or grove complexes along the western flank of the Sierra Nevada mountains in Central California. Many of these trees live for thousands of years: The oldest sequoia is more than 3,200 years old. In North America, only bristlecone pines grow longer. The 2020 and 2021 fire seasons were a wake-up call: flames had killed between 13 and 19 percent of all giant sequoias more than 4 feet in diameter, and many trees were far larger.

Batteries of the future? How cotton and seawater might power our devices - In markets where consumers appear to really care about the sustainability of the products they buy, appropriately sourced alternative battery materials might have more of a chance – whether batteries are made with biowaste-derived carbon or any other potentially more sustainable substance. The public could play a big role in really pushing that effort forward.

Designing cities for 21st-century weather – A data-driven model to predict how urban areas across the country will grow by 2100 found that how a city is laid out or organized spatially has the potential to reduce population exposures to future weather extremes. Carefully designed urban land patterns cannot completely erase increased population exposures to weather extremes resulting from climate change, but it can generate a meaningful reduction of the increase in risks.

Stunning 2,700-Year-Old Sculpture Unearthed in Iraq – 18 tons of alabaster. 2,700 years old. 12.5x12.8 feet. Largely intact except for its head which is missing.

Larger Beaks, Smaller Bodies: Could Climate Change Literally Change Birds? – A study analyzed 129 species of North American migratory birds collected over the prior 40 years and found bodies are shrinking and wings growing longer. Smaller species of birds, like tiny warblers or kinglets, shrink faster than bigger birds like robins and grackles, so their rate of change over the 40 years, is much, much faster. They’re able to maybe adapt to warming temperatures faster than these bigger birds.

A step closer to injection-free diabetes care: Innovation in insulin-producing cell – Potential this safer and more reliable way to grow insulin-producing cells from a patient's own blood could eventually allow transplants without the need for anti-rejection drugs.  

The Life and Death of American Dams - Many dams are now poorly maintained, clogged with silt, and pose an increasingly high risk of catastrophic failure. The recent recognition of the damage dams cause and the movement to remove them is part of the rewilding of America, long overdue.

An exotic tick that can kill cattle is spreading across Ohio – Asian longhorned ticks. The size of a sesame seed in some life stages and pea-sized when engorged. Surveillance showed they returned the following summer to the farm despite the application of pesticides in 2021. Asian longhorned ticks' secret colonization weapon is the ability to reproduce asexually, with each female laying up to 2,000 eggs at a time -- and all 2,000 of those female offspring able to do the same.

How Urban Design Impacts Public Health – Urban planning and design affects everything from air quality to temperature to risk of injury on roadways. Often with developers of public spaces it’s a sin of omission rather than of commission. In many cases, what is rarely apparent is what the health cost is, because that cost is born in a different sector and often at a different time.

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

The ground is deforming, and buildings aren’t ready – Underground climate change in urban areas where heat islands underground cause enough expansions and contractions to damage building foundations…particularly in older buildings.

How noise pollution impacts nature – A study out of Vail, Colorado, showed that increased trail use by hikers and mountain bikers disturbed elk so much the cows birthed fewer calves. Another out of Grand Teton National Park showed that backcountry skiers scared bighorn sheep during winter when food was scarce, with potentially lethal consequences.

Hospital understaffing and poor work conditions associated with physician and nurse burnout and intent to leave - The study from the University of Pennsylvania School of Nursing found that physicians and nurses, even at hospitals known to be good places to work, experienced adverse outcomes during the pandemic and want hospital management to make significant improvements in their work environments and in patient safety. The solutions to high hospital clinician burnout and turnover, they say, are organizational improvements that provide safe workloads and better work-life balance NOT resilience training for clinicians to better cope with adverse working conditions.

The simple ways cities can adapt to heatwaves – Heat monitoring and planning is become more important for cities…the climate emergency in cities is a health emergency.

New biodegradable plastics are compostable in your backyard – New plastic made from blue-green cyanobacteria that isstronger and stiffer than previous plastics from the same raw ingredient. They can be recycled…but also degrade rapidly in the environment.

Giant Hand Axes Discovered in England Point to Prehistoric Humans’ ‘Strength and Skill’ – More than 300,000 years old perhaps from an interglacial period. Early Neanderthal people inhabited Britain then…and maybe other archaic human species too.

Germs, genes and soil: tales of pathogens past – DNA sequencers and powerful computational tools…applied to ancient microbes…probing their role in human history. This article describes how the work is done, ethical considerations…using examples of what has been accomplished so far. The field of archaeogenetics is just beginning.

Back from the Dead: New Hope for Resurrecting Extinct Plants – There is a global effort to digitize herbaria specimens which had helped identify holdings of extinct plants…sometimes finding seeds. And then the challenge is how to best attempt to grow old seeds.

Pain risk varies significantly across states – Pain due to arthritis varies geographically in the US – with the moderate to severe pain being 23% in West Virginia vs 7% in Minnesota.  There is also a difference between people that did not complete high school…and those who obtained at least a bachelor’s degree – with the delta being greatest in West Virginia, Arkansas, and Alabama. There is a need to focus on the macro-level policies (i.e. generally at the state level) while continuing current individual interventions.

The Acropolis Adopts Crowd Control Measures for the First Time – The post-pandemic travel surge is overwhelming at some places – including the Acropolis!

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.

Digesta: An overlooked source of Ice Age carbs – Partially digested vegetable matter from large herbivores (such as bison) might have provided carbohydrates and other macro nutrients reducing the burden of ‘gathering’ for a time after an animal was slaughtered. Perhaps during migration, it was the dominant source of carbohydrates in a situation with reduced accessibility of plants. And maybe women participated in hunting to a larger extent than previously thought; ‘grave goods’ in burials found that perhaps 30-50% of all large-game hunters in the Americans during the late glacial era may have been female!

Anemia found to be common in ancient mummified Egyptian children – CT scans were done on 21 child mummies (between ages 1-14 at death) to study the skeleton inside the wrapped remains. 7 of the children had pathological enlargement of the cranial vault, typically associated with anemia. The study also found a child that died less than a year after birth of thalassemia (the body could not produce hemoglobin).

Bathing through the ages: 1300 – 1848 – 14th and 15th century bathhouses provided services beyond bathing (lancing abscesses, pulling teeth, steam rooms, mineral baths, cupping, herbal concoctions); they helped shape the public health services of larger cities as they grew, and health conditions deteriorated. By the 16th century, bathhouses started to disappear as Europe was ravished by plague, smallpox, and syphilis. But – by the 1800s, sanitation reformers were arguing that making bathing facilities available to the poorest classes of society offered an ‘affordable and immediate way’ of improving public cleanliness and health. Bathhouses, along with waterworks and sewage systems, laid the foundation for the UK Health Act of 1848.

Glass or Plastic: which is better for the environment? – There is not a clear-cut answer. I will lean toward glass because of its non-toxicity….but I also realize we need to improve the ways we use it (less single use) and recycle it (better sorting and improved processing that avoids melting it twice),

Greener batteries – Batteries with Organic Electrode Materials (OEMs) are one alternative that is being researched…in this case using azobenzene by a research team at a Chinese University. Hopefully there are researchers around the world also focused on producing greener batteries.

Protein powders: When should you use them? – I think of protein powder as an ultra-processed food….a food I only want to use if I can’t manage to get enough protein from unprocessed or lightly processed foods in my diet. It is not something I want to use every day!

Long Reviled as ‘Ugly,’ Sea Lampreys Finally Get Some Respect – Not so long ago…lampreys were an organism that seemed destined for extinction because we only saw it as a predator that wiped out the Great Lakes lake-trout fishery. Now, the consensus is that, in their natural habitat, marine lampreys are “keystone species” supporting vast aquatic and terrestrial ecosystems. They provide food for insects, crayfish, fish, turtles, minks, otters, vultures, herons, loons, ospreys, eagles, and hundreds of other predators and scavengers. Lamprey larvae, embedded in the stream bed, maintain water quality by filter feeding; and they attract spawning adults from the sea by releasing pheromones. Because adults die after spawning, they infuse sterile headwaters with nutrients from the sea. When marine lampreys build their communal nests, they clear silt from the river bottom, providing spawning habitat for countless native fish, especially trout and salmon. Wow!

The Pacific Garbage Patch Is Home to Coastal Species—in the Middle of the Ocean – A surprise for researchers…they found shrimp-like arthropods, sea anemones and mollusks, Pacific oysters, orange-striped anemones and ragworms. Crustaceans were taking care of eggs and anemones were cloning themselves. This does not make the Garbage Patch acceptable!

Photography In the National Parks: Same Spot, Different Time / Season / Weather – Spots in Yellowstone, Mount Rainier, and Olympic National Parks.

Greater fat stores and cholesterol increase with brain volume, but beyond a certain point they are associated with faster brain aging – People in wealthy countries have largely grown accustomed to eating more and exercising less -- habits that are associated with decreased brain volumes and faster cognitive decline. This study looks at indigenous people (two tribes in Bolivia that live along tributaries of the Amazon). The tribe that was closer to our subsistence ancestors had the lowest rates of hear disease and minimal dementia; in this group - BMI, adiposity and higher levels of "bad" cholesterol were associated with bigger brain volumes in older adults!

A Different Kind of Vase

I bought several of the MODGY Expandable Flower Vase back in October when I toured the Museum London (in London, Ontario). They are great gifts because they are flat and light (easy to wrap/ship) – made of heavy, reusable plastic that expands when it is filled with water. What a clever idea! Last week I finally picked the one I would keep – the Louis Comfort Tiffany Field of Lilies vase. When filled with water, it was stable on the windowsill; adding the bouquet was very easy and the cinching at the top makes it easy to position the flowers!

I’m giving away the others I bought…but maybe I’ll order some additional vases. There are so many to choose from on the MODGY site!

Energy crisis: How living in a cold home affects your health – The coming winter is going to be very difficult for many – particularly in Europe.

Parks of the 21st century: new ways to reinvent abandoned land – Parks always are signs of hope…the greening of places that might have been eyesores in the past. I wondered how much toxic remediation had to occur for some of the sites they described; its encouraging that we can clean up the messes we’ve made in the past!

Alcohol caused one in eight deaths of working-age US adults – The data used from the analysis was pre-COVID-19 pandemic. Recently, the CDC has released data for 2019 and 2020 and it shows a larger-than-normal 26% spike in the alcohol-induced deathrate. In 2020, alcoholic liver disease and mental/behavioral disorders were the leading underlying causes of alcohol-induced deaths. Sad numbers….lots of people and their families impacted.

A field guide to the unusual raptors of the Southern US – I was pleased to see the snail kite in this article – a bird I saw on a birding trip to Florida in 2019.

Farmers in China, Uganda move to high-yielding, cost-saving perennial rice – Very positive results. Hopefully we will eventually have perennial forms of other grains (wheat in particular).

The weirdest places you can find wild turkeys – Wild turkeys have made a comeback since the early 1900s…a restoration success story. Part of the Thanksgiving vibe this week!

Breast cancer survivorship doubles – An analysis of Canadian data from the 2007-2001. The study also highlighted the long-term side effects in these survivors…the need for new therapies to improve the health of women after surviving breast cancer.

Permanent Standard Time Could Save Lives, Explained by A Sleep Expert – I don’t like changing to/from daylight savings time; before reading this article, I didn’t care which one we chose to make permanent. Now I am convinced that we should stick with standard time! There are too many negative health impacts to staying on daylight savings.

How to avoid bad choices – The article is about the research on how to teach children ‘decision-making competence’ – not just a measure of raw brainpower but how well someone is able to appraise situations. There are many approaches but the goal is to get children and adolescents to start thinking about risk and danger in a more analytical way….on the way to adulthood.

Blind spots in the monitoring of plastic waste – The amount of plastic waste in rivers could be up to 90% higher that previously assumed. The current measurements are mainly based on surface observations…but plastic can be suspended or sink! This study tracked 3,000 particles from 30mm to larger objects like plastic cup. Knowing where the plastic is helps guide where clean up would be the most effective.

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.

See the vibrant, long overlooked colors of classical sculptures – Greco-Roman marble sculptures were covered in bright hues (polychromy) originally!

Pioneering recycling turns mixed waste into premium plastics with no climate impact – Wouldn’t it be great if suddenly mixed waste could replace fossil raw materials for ALL plastic production?

Invasive species taking over some American forests - Amur honeysuckle (a shrub from Asia) is a big culprit. Callery Pear (the ‘wild’ version of the Bradford pear) is a close second.  I just cut down a Callery Pear that was growing in the front bed of my new house in Missouri…almost obliterating a crepe myrtle! Other foreign species that have become problematic: porcelain berry, tree of heaven, winged euonymus, European buckthorn, Oriental bittersweet, common privet and lesser periwinkle...Norway maple, Amur cork tree and white poplar along with herbaceous species such as lesser celandine, garlic mustard, Japanese knotweed and Japanese stilt grass.

A Surprisingly High Number of Wildfires Are Caused by Electrocuted Birds – Awful….good that there is a way to reduce the carnage…at less cost than the consequences of the fires.

Rural areas near coast will bear the brunt of US sea-level rise – Analysis focused on the Chesapeake Bay…marshes forming where forest and farmland is today.

Once-Common California Bumble Bees Have Gone Missing – The survey did not find the formerly abundant Western bumble bee. The last statewide survey was conducted 40 years go…and a lot has happened in that time: habitat loss, pesticides, and climate change. None of the species were doing well. Big problem – since bumble bees help pollinate $3 billion worth of crops in the US each year (including tomatoes, peppers, and cranberries).

Scientist war of links between soil pollution and heart disease – The author of the study commented: “Until we know more, it seems sensible to wear a face mask to limit exposure to windblown dust, filter water to remove contaminants, and buy food grown in healthy soil."

New Mexico Wildfire Spawns Fire Cloud – A pyrocumulonimbus cloud formed; the vertical plume reached the tropopause….an altitude of about 12 kilometers.

Heatwaves are altering our everyday lives – The new normal but we aren’t very well prepared for it; there are some obvious adaptations that are needed – particularly to electrical networks. No one wants infrastructure to fail at a critical time.

Well-preserved iron age arrow discovered in Norway – The arrow was recovered from a glacier…iron arrowhead, sinew, tar, thread, shaft, and feather fletching was preserved. It is about 30 inches long.

Rigid waterproof coating for paper aims to reduce our dependence on plastic – Interesting…would be great if it could speed the transition away from plastic for food packaging particularly. The article said the chemicals break down over time into harmless components…but didn’t say how long that took.

Chemicals that linger for decades in your blood – So many chemicals introduced in my lifetime are probably still in my blood. I can remember the spraying of DDT for mosquitoes in the ‘60s….one instance particularly of the straying truck going down the farm road near my grandparents house as we played in the back yard. How much of my exposure do I still have…did I pass along to my daughter?

Ultraviolet light reveals radiant hidden beauty of flowers – A project during the COVID-19 pandemic…beautiful results.

Archaeologists Unearth 3,000-Year-Old Giant Statues in Sardinian Necropolis – Over 7 foot tall…with almost emotionless expression, blocky nose and deep-set eyes. The two found most recently were boxers but about two dozen others have been found since the mid-1970s: 16 boxers, 4 archers, and 5 warriors.

Top 25 birds of the week: May 2022! – Bird appreciation….a source of beauty in the world.

Disparities in natural gas leak prevalence in US urban areas – Why can’t pipeline companies do better…not wait around until regulation requires them to do it? We should be more critical of the companies that they are not actively reducing leaks in their pipelines.

Top 25 birds of the week: Bird Habitats! – Beautiful birds! I always enjoy seeing photographs…seeing birds I know and some I don’t!

The Jumping Slugs of the Pacific Northwest – A little different than the slugs I’ve seen. These have a vestigial shell on the top of their ‘hump.’ There was a new-to-me skeletal name in the article: slugs have a hydrostatic skeleton!

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!

Fresh water from thin air – Another technology that might help dry regions….using hydrogels (like the ones currently used in diapers!).

What’s The Construction Industry Blueprint to Cut Carbon? – I wanted more specific examples…was a little disappointed that this article did not provide them, but maybe that would have made it a long article! I hope to see more on this topic.

Higher education must reinvent itself to meet the needs of the world today. Enter the distributed university – The pandemic has highlighted the challenges the current higher education model is facing. The ideas in this post are a start but don’t seem to be fully developed to push into full implementation. More work needs to be done to enable transition from the existing model to a new one that is more responsive to the needs not only of undergraduate students but for graduate students and continuing education. The sources of money in the current model don’t match up well. For example – in the US the sports programs (football) is a big money maker for many universities; how does that map into the new model (or do we want it to).

Upcycling plastic waste into more valuable materials could make recycling pay for itself – Hope this research can be transitioned into commercial use….we have to improve the recycling processes that are being used today. Too much is still ending up in landfills.

Fossil pollen reveals the African origins of Asia’s tropical forest – Research on Borneo’s Dipterocarps (very large trees with buttress roots, smooth/straight trunks, high crown) using fossil pollen reveals their origins in Africa…spread through India before it crashed into Asia…and then to Southeast Asia. The forests in India shrank as the climate became drier. These trees need a wet, seasonal climate to survive.

Mummification in Europe may be older than previously known – Analysis of bodies found in Mesolithic shell middens in Portugal reveal that they were probably mummified before being placed there 8,000 years ago. The description of the way the researchers came to that conclusion was interesting…a lot has been learned about forensics since the 1960s when the bodies were originally found. The oldest intentional mummification known before this finding was from the Chinchorro hunter-gatherers living in the coastal region of the Atacama Desert in shell middens (around 7,000 years old).

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!

A Mosaic From Caligula’s ‘Pleasure Boat’ Spent 45 Years as a Coffee Table in NYC – Still a lot of mystery about how the mosaic got from its recovery when Lake Nemi was drained by Mussolini and then becoming the top of a coffee table for 45 years. It was seized in 2017 and returned to the Italian government.

Roadrunner: Meet the Real Bird Behind the Cartoon – I can remember seeing one a little north of where my parents live now (north of Dallas) in the 1980s…but they are probably long gone from that area now. I’ve seen them in west Texas more recently; one was at a rest stop between San Antonio and Laredo. They always seem to thrive in relatively harsh environments.

The bustling hidden world of hedgerows – The closest we come in North America to hedgerows are fencerows or windbreaks….and even those have been reduced over the years. Near where I live the advent of glyphosate/Roundup ready crops has eliminated the herbaceous growth along the edges of fields which in the past included milkweed and other plants that were attractive to butterflies and other small animals.

Master Artisans Fixed Mistakes Made by Apprentices at Ancient Egyptian Temple – I enjoyed the 6 minute video in this post…it’s quiet enough to hear the birds in the ruins.

Managing water resources in a low-to-no-snow future – We need to be thinking of adaptations to this manifestation of climate change now rather than waiting since the solutions will be challenging….take time to design and construct.
