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.

Intact Roman-Era Sarcophagus Discovered in France – From the 2nd century AD, sealed with iron clasps, weighs about 1,700 pounds. It hasn’t been opened yet, but x-rays and an endoscope camera have revealed the contents.

Selective removal of aging cells opens new possibilities for treating age-related diseases - Aging cells, known as senescent cells, contribute to various inflammatory conditions and age-related ailments as humans age. The researchers created technology that specifically targets organelles within aging cells to initiate the cell’s self-destruction. There is still a lot of work to be done (and preclinical and clinical trials).

Cloud Rings Around a Volcano Takes Top Prize in ‘Weather Photographer of the Year’ Contest – Capturing dramatic weather moments…

Brainless Jellyfish Are Capable of Learning - Experiments that provide evidence that box jellyfish are capable of associative learning, or the process of linking two unrelated stimuli together.

How maps can protect children from extreme heat - Heat is becoming increasingly dangerous and it's a threat that is not going away. Community heat maps may not solve the long-term problem, but they are a step in the right direction, by providing awareness and empowering vulnerable children and their families.

Stunning 16th-Century Turkish Bath Reopens in Istanbul - Called the Çinili Hamam, the revitalized site won’t offer traditional bathing until 2024. In the meantime, however, it will feature private gardens and contemporary art in the newly discovered Byzantine cisterns that originally fed the baths. Nearby, a new accompanying museum will display objects associated with traditional bathing rituals—including towels, bowls and ornately decorated wooden shoes—and explain the baths’ original water and heating systems. It will also showcase artifacts from the Byzantine, Roman and Ottoman periods uncovered during the restoration.

The Resiliency of Urban Wildlife - Four distinct sets of traits that help urban wildlife adapt and survive in environments that seem hostile to animals: diet, body size, mobility, and reproductive strategy. Important to know since if you look at the traits animals are adopting to survive in urban environments, you can see how cities could be modified to become more habitable to a wider variety of species.

See the Trove of Ancient Treasures, including a Shrine to Aphrodite, Just Discovered in an Underwater City Off the Coast of Egypt - Thonis-Heracleion was Egypt’s biggest port for centuries, before being surpassed by Alexandria. The city was eventually lost thanks to a combination of rising sea levels, earthquakes, and tsunamis, disappearing beneath the waves along with a large section of the Nile delta. It was largely forgotten for centuries, until 21st-century archaeologists began investigating.

New Patch Inspired by Octopus Suckers Could Deliver Drugs Without Needles - A tiny, drug-filled cup that sticks to the inside of the cheek like an octopus sucker. The device is easily accessible, can be removed at any time and prevents saliva from dissolving the drug, which gets absorbed through the lining of the inner cheek.

Buried ancient Roman glass formed substance with modern applications - Photonic crystals were created by corrosion and crystallization over centuries. If we could significantly accelerate the process in the laboratory, we might find a way to grow optical materials (i.e. materials for communications, lasers, solar cells) rather than manufacture them.

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

Abandoned Lands: A Hidden Resource for Restoring Biodiversity – Nature colonizing abandoned land…maybe we need to learn to help it along. The amount of land under agriculture globally has been in decline since 2001. Sometimes the abandonment is not driven by economic, demographic, or social factors, but by pollution or industrial disasters. Hundreds of square miles of radioactive former farmland around the stricken nuclear reactors at Chernobyl in Ukraine and Fukushima in Japan are now within exclusion zones and could be without human occupation for centuries to come.

How to build for aging in place - Aging-ready homes address two core needs—single-floor living and bathroom accessibility—by providing a zero-step entry, a first-floor bedroom, and a full first-floor bathroom with at least one accessibility feature. Today only 10% of American homes are ‘age ready.’ When my husband and I bought our current home, we were conscious of buying something that would help us age-in-place. Everything is on one floor except for the laundry room….so we might have to eventually add an elevator to the house.

The Mississippi is Mighty Parched – The river south of Memphis has narrowed considerably in the past 2 years. Barge companies reduced the weight carried in many shipments in September because the river was not deep enough to accommodate their normal weight. Much of U.S. grain exports are transported down the Mississippi; the cost of these shipments from St. Louis southward has risen 77% above the three-year average. The lack of freshwater flowing into the Gulf of Mexico has also allowed saltwater to make its way up the river and into some water treatment plants in southern Louisiana.

Electric Cars Are Transforming America’s Truck Stops – I’ve been noticing the changes described in this article as I travel. More of truck stops have banks of chargers…and the Pilot just north of Denison has better food and a larger shopping/eating area… Adding charging equipment for electric cars is a major transformation for truck stops and travel centers but represents a new business opportunity.

The seed guardians in the Andes trying to save the potato – Climate change/disease are risks that all species are facing. There are 1,300 varieties of potato growing in the Andes. Potato Park, located near the Peruvian town of Pisac, was founded by six indigenous communities in 2002 to preserve the genetic diversity of potatoes grown in the region, as well as the cultural heritage of the people that grow them.

Chemical Analysis of Viking Combs Hints at Long-Distance Trade – 85-90% of the combs found in a Viking settlement in Germany, came from northern Scandinavia – made of the antlers of reindeer. So large scale trading between the two sites was happening as early as AD 800.

See Ten Stunning Images from the Bird Photographer of the Year Awards – Birds and photography…images to enjoy.

Japanese Scientists Find Microplastics in the Clouds Above Mount Fuji – Maybe we should be more surprised if we looked and didn’t find microplastics!

Why Flamingos are Showing Up in the U.S. this Fall – The short answer is hurricanes…specifically Hurricane Idalia. Flamingos are strong fliers and will simply return south eventually.

A Sample of Ancient Asteroid Dust Has Landed Safely on Earth – We were at the launch of OSIRIS Rex in September 2016…so I continue to follow news about the mission.

Nature's great survivors: Flowering plants survived the mass extinction that killed the dinosaurs – Ancestors of orchids, magnolia, and mint all shared Earth with the dinosaurs…and are thriving today.

Woman Uses Hidden Cameras to Get Candid Look at Birds in Her Backyard – Birds (and squirrel, chipmunk, and groundhog) at the food bowl.

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.

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

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.

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

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

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

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

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

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

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

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

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

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

More Used Puzzles

The county just north of where I live is more populous and their Friends of the Library sale was a lot larger – held in a building of the county fairgrounds. They filled the large building with tables loaded mostly with books but there were some CDs and a few puzzles/board games. I bought the best of the 500-piece puzzles to take to my parents – 17 boxes that contained 28 puzzles…for the bargain total of $52! I was grateful that my husband went with me to help get them into bags…through checkout…and into the car. I’ll be taking them to Carrollton in a few days….adding them to the stack I created last month (probably a little reduced with my parents finishing some of them). They enjoy having lots of puzzles to choose from!

In the 1990s, I went to used books sales…and staggered out with so many books I could hardly lift my bags. But now I am not tempted. I read eBooks…and for things like planning travel, I do searches to get the most current information rather than buy dated books. It felt a little strange to go to a large used book sale and buy nothing at all. My husband was not tempted either.

Pawpaw Experience

The first ‘new-to-me’ food that appeared in my CSA share this season is pawpaw! I had heard about them but never eaten one. I cut the fruit in half….right along the seed-line evidently. The pulp was custard-like and very sweet. I like it so much that I planted the seeds in a corner of my yard…hoping to establish a pawpaw patch!

Pawpaw is native to North America and grows well in Missouri where I live. So – I am including it as another native that will eventually reduce the amount of lawn in my yard. It might be years before the trees produce fruit; I like the prospect of enjoying them in the future. Maybe the fruit will provide more food in our yard for the birds and squirrels too…and the leaves will feed zebra swallowtail larvae.

Native Plants for our Missouri Yard

There are 5 new native plants at our house! I bought them at the Fall Wildflower Market located at the Shaw Nature Reserve about a week ago and have them all transplanted into our back yard:

Callicarpa americana - American Beautyberry

Solidago speciosa - Showy Goldenrod

Ratibida pinnata - Grayhead Coneflower

Pycnanthemum pilosum - American Mountain Mint

Aralia racemosa - American Spikenard

 The largest plant – and the one I had been wanting since I bought one for my sister last spring – is Callicarpa americana - American Beautyberry. The one I bought already has some berries on it which I hope will turn purple this fall. In a few years it should be the dominant plant in the area where a pine tree used to be in our yard (it fell over and had to be hauled away…the stump ground up).

I also planted three of the other plants (smaller) in that same area and will propagate them to other parts of the yard as they become established: showy goldenrod, grayhead coneflower, and American mountain mint.

The American Spikenard is planted at the edge of a flowerbed overflowing with violets where I can see it from my office window. It is a shade-loving plant that has red berries in the fall. It won’t this year but I hope it does next year….food for birds and a good scene from my window.

I’ll post again about how the native plants (these and the fragrant sumac I planted earlier last summer) survive (or not) in November.

Kitchen chemistry hacks explained – How many of these did you know before this article? I knew about lemon juice slowing browning of fruit…I’m going to try the ‘brown onions more quickly’ and ‘chop onions more comfortably.’

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.

What Does It Take to Photograph a Bat Cave? – Photographer Stephen Alvarez….lots of specialized photographs.

Community Supported Agriculture (2)

Acclimating myself to being a CSA member (Milsap Farms) again is still a work in progress!

The third week, I was out of town; my husband took the whole distribution to my daughter: watermelon, kale, green beans, cucumber, bell peppers, zucchini, and mixed greens.

My son-in-law cut up the watermelon in wedges and we got half of it when I got back. My daughter also decided that she didn’t have an immediate use for zucchini, so I enjoyed that unexpected bounty too. What a difference it makes to have my daughter close enough to handle the share when I am gone! This probably cinches our continued participation next year; the only question still outstanding is whether we go with a full share or the smaller one that we are getting for the remainder of this season.

The fourth week we split down the middle except for the sweet potato leaves which I have for myself. Each of us got 2 carrots, a garlic head, 2 bell peppers, half the scallions, and half the bag of basil.

I am anticipating some excellent salads and then freezing any basil or sweet potato leaves I can’t use soon enough. Once frozen they can be used in smoothies or soups/stir fry. I didn’t have an extra freezer in my Maryland house; now that I do in Missouri, I have lots of options!

Extreme Weather is the “New Norm” - There is high confidence that human induced climate change from greenhouse emissions, is the main driver.

A Visit to North America's Only Authenticated Viking Site - L’Anse aux Meadows National Historic Site (in Newfoundland), the only authenticated Viking site in North America. Credit for this discovery in the 1960s goes to Norwegian explorer/writer Helge Ingstad and his archaeologist wife Anne Stine.

Earth’s hottest month: these charts show what happened in July and what comes next – The intense heat this summer has killed Saguaro cactus!

Ötzi the Iceman’s Genome Sequenced – 90% of his ancestry came from Anatolian farmers. Genome analysis revealed he had high skin pigmentation, dark eyes, and male pattern baldness!

Common wristbands 'hotbed' for harmful bacteria including E. coli, staphylococcus – I am glad the band on my Garmin is metal since it likely harbors a lot less bacteria than a plastic, rubber, cloth, or leather band. However, I still need to get in the habit of cleaning it more often.

Fully Intact Giant Panda Skeleton Discovered in Chinese Emperor’s 2,000-Year-Old Tomb – There was also an Asian taper in the tomb.  The article suggests that perhaps the animals were included in the tomb as a part of a replica royal garden.

Medications for chronic diseases affect the body's ability to regulate body temperature, keep cool - Medications used to treat common chronic conditions, like blood thinners, blood pressure drugs, Parkinson's disease/Alzheimer's medications, and some chemotherapy drugs, can make it harder for the human body to handle hot weather by reducing its ability to sweat or increase blood flow to the skin. Hopefully doctors will become more aware of this issue – particularly for their elderly patients that are already at increased risk because of their age for heat related issues.

Trapped: Australia’s extraordinary alpine insects are being marooned on mountaintops as the world warms – The grasshopper with the turquoise exoskeleton snagged my attention. This movement up mountains and then becoming marooned must be happening around the world.

Chromium replaces rare and expensive noble metals – Osmium and ruthenium replaced with, much more abundant, chromium? More research is needed, but it might be possible.

Photos of the Week – August 13, 2023 from the Prairie Ecologist – Another example of enjoying some photography even when it is hot and humid!

Carrollton Yard – August 2023

Weeks of 100+ degree temperatures in Carrollton, TX were hard on the yard/garden. Frequent watering helped. Still - the hydrangea that is usually very lush green and blooming is drying out – hopefully it will come back from the roots next year.

There is still a lot of green in the garden areas of the yard. Crape Myrtles seem to thrive in the high heat if they get enough water.

The naked lady lilies are almost done for the season. My favorite picture of the morning was one of the last flowers – full of water droplets from the sprinklers.

There is a lot of seed production too. The red yuccas look as they always do but other plants seem to have more than the usual seeds…maybe a good strategy to survive to grow another year.

There was a large spider in the flower bed near the front door – a female Argiope aurantia (yellow garden spider). The first time I saw it, all was quiet on the web.

The next day, the spider was feeding on something! There were a few droplets of water from the sprinklers too. The web seemed to be very sturdy – and built in a good place.

Overall, attention to watering (sprinkler system and supplement in key areas) has sustained the yard. Many in the neighborhood look thoroughly dry…and dying. If this is what the summers will be like in the area from now on – then landscaping will need to change significantly.

Community Supported Agriculture (1)

I enjoyed my membership in a Community Supported Agriculture (CSA) when I lived in Maryland. When I first moved to Missouri, I decided that I would try to simply go to local Farmers Markets for locally grown produce. That remained my plan until recently when I realized that one of the best things (for me) about belonging to a CSA is the prompt to enjoy more variety…maybe even a totally new-to-me veggie or herb. So – I researched Springfield MO area CSAs and discovered that I could become a mid-season member of  Milsap Farms!

It is a bit different from the CSA in Maryland.

  • Instead of being less than I mile from where I live, it is on the other side of Springfield. I pay a little extra for delivery of my share to my front porch.

  • In Maryland I went to the farm every week and did ‘swapping’ while I was there. In Missouri, the share composition/swapping is handled with an email prompt and then an online app which is completed by the day before delivery. I didn’t quite get the routine the 1st time around, so I got the default delivery for that week. By the 2nd delivery, I was comfortable…knew when to look for the email and do the tweaking.

  • My daughter lives closer to me now so we can split up the share after I receive it. For example, out of the first share I gave her half the carrots, celery, herbs, and onions (she suggested that I keep the kohlrabi since I like it better than she and her husband do). For the rest of this season (until the end of October), we are getting the small share and evaluating how well we like the CSA; at this point, we think we’ll sign up next year…but still need to decide if we want a small or full share.

The first week’s share (picture below) included: carrots, celery, Thai basil, dill, onions, and kohlrabi The second week included: salad mix, radishes, green bell peppers, pea shoots, basil, carrots, and watermelon.

So far – a positive experience!

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.

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

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

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

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

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

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

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

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

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

Nearly Two-Thirds of All Species Live in the Ground, Scientists Estimate - Soils are richer in life than coral reefs or rainforest canopies, providing a home to nearly two-thirds of all species. The study is the first to tally the total number of soil dwellers, large and small, finding that more than twice as many species live in the ground as was previously thought: 59 percent of all species depend on soil for their survival, including 90 percent of fungi, 86 percent of plants, and 40 percent of bacteria.

Incredible Winners of Light Microscopy Awards Show Artistry of Scientific Imaging – The beauty of microscopic life….

Research Sheds Light on Steamboat Geyser’s Eruptions, Past and Present – They discovered that the strength of shaking decreased as snow depth increased. The ability of snow to absorb sound makes a difference!

Stunning Fields of Sunflowers Are Blanketing North Dakota – The states farmers grew 625,000 acres of sunflowers this year…and they bloom throughout August. Maybe one year we’ll make the trek to see them; I haven’t been to North Dakota before.

Exceptional Winners of the 2023 Nature inFocus Photography Awards – Beautiful…and educational. My favorite image is the ant with aphids (“A Sappy Alliance”).

What Pots Say—and Don’t Say—About People – “What can such a well-traveled artifact tell us about the people who left it in the ground? Its culture of origin may be less important than how it fit into life where it was found.”

Microplastics found in human heart tissues, both before and after surgical procedures - Everywhere scientists look for microplastics, they've found them -- food, water, air and some parts of the human body….even in the heart. But it still is not known how/if the microplastics impact the cardiovascular system.

Microalgae vs. Mercury - In the search for ways to fight methylmercury in global waterways, scientists at Oak Ridge National Laboratory discovered that some forms of phytoplankton are good at degrading the potent neurotoxin.

Risk of fatal heart attack may double in heat wave and high fine particulate pollution days – A study from China that included 202,000 heart attach deaths.

July Was Likely Earth’s Hottest Month on Record – The last sentence of the article: ‘Well, this is probably one of the coolest summers you’ll ever see in your life.’ ... It is quite scary to put it this way.

Climate Change Temperatures Killing Death Valley's Bristlecones – 70% mortality rate over the past decade.

The Australian town where people live underground – Coober Pedy…where most of the people live underground in abandoned opal mines or intentionally excavated spaces!

Looking Down on the Andes – Pacific Ocean, Atacama Desert, Andes…Chile, Argentina, and Bolivia. Image taken from the International Space Station.

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.

Neolithic Necklace from Jordan Reassembled – Jewelry that was beautiful long ago…and still is. Beads of stone and shell primarily.

UNESCO Recommends Adding Venice to List of World Heritage in Danger – UNESCO is indicating that Venice’s proposed solutions are “currently insufficient and not detailed enough and should be subject to further discussions and exchanges.” I’m a little surprised that Venice hasn’t been on the list for years.

'Time-traveling' pathogens in melting permafrost pose likely risk to environment – Quantifying the risks using simulations. The results so far estimate that 1% of the invaders (ancient pathogens) are unpredictable…some could cause 33% of the host species to die out while others could increase diversity by up to 12%. Outbreak events caused by ancient pathogens represent a substantial hazard to human health in the future.

In Peru, discovery of ancient ruins outpaces authorities' ability to care for them – Lima is home to more than 400 known pyramids, temples and burial sites, many of which predate the Incas and are known in Spanish as "huacas"…and archaeologists continue to find/dig new sites! 27 sites are open to visitors…the rest are deteriorating (or actively being destroyed by looters or squatters).

Inflammation discovery could slow aging, prevent age-related diseases – Researchers at the University of Virginia School of Medicine have discovered that improper calcium signaling in the mitochondria of certain immune cells (macrophages) drives harmful inflammation. Creating drugs that increase calcium uptake by mitochondrial macrophages could prevent harmful inflammation and slow age associate neurogenerative diseases.

Piecing Together the Puzzle of Oman’s Ancient Towers – 4,000 years old! And there are over 100 known towers found today in Oman and the United Arab Emirates. The purpose and function of the towers remain largely a mystery although water might be involved. They appear to be built close to places where there is/was access to surface water.

Lake Tahoe’s Clear Water Is Brimming with Tiny Plastics – Its water contains the third-highest amount of microplastics among 38 freshwater reservoirs and lakes around the globe! Lake Tahoe is also full of garbage ranging from sunglasses to car tires; 25,000 pounds of debris was removed from the lake between 2021 and 2022.

Dementia becomes an emergency 1.4 million times a year – And these patients are 2x more likely to be seeking emergency care after an accident or a behavioral/mental health crisis. Once a person with dementia is in the emergency department, it can be a very disorienting experience. "Even routine blood draws from unfamiliar staff can be a very scary experience for a patient with advanced dementia."

Decades of public messages about recycling in the US have crowded out more sustainable ways to manage waste – To often we overlook waste reduction and reuse in favor of recycling.

Steel Industry Pivoting to Electric Furnaces - Iron and steel production accounts for 7% of carbon emissions worldwide – using coal in blast furnaces. But – progress is being made. 43% of planned steelmaking capacity globally will rely on electric-arc furnaces, up from 33% last year! Even so – the rate of transition needs to be increased to stay on track for only 1.5 degrees C warming.

An elegant enigma – A shipwreck discovered 30 feet below the surface 15 years ago…what we know (and don’t know) about it after study of the 1,500 objects recovered including textiles in 4 chests. The name of the ship is still unknown but the construction indicates it was a Dutch trader constructed around 1645 and sank around 1660.

At Peru temple site, archaeologists explore 3,000-year-old 'condor's passageway' – A 3,000 year old sealed corridor in a massive temple complex built by the ancient Chavin culture.

Does Nature Need a Trigger Warning? – A thought provoking post. Predators must be part of our conservation actions…and need to be valued as they are rather than simplistically.

Two-Hundred Years of Written Observations of Kīlauea's Summit Activity – On August 1, 1823, an English missionary visited the summit and published his observations (I found the book online -available on Internet Archive…Chapter 6 begins on page 121…image below). Mark Twain visited in 1866 and trekked across the caldera floor to Halema’uma’u, watching “a heaving sea of molten fire of seemingly limitless extent.” There are several links in the article that are worth following. My favorite is the USGS Views of a Century of Activity at Kilauea Caldera – A Visual Essay.

How Texas is racing to thwart the heat  - Unfortunately, planning for heat is not as well-developed in the US as planning for other hazards like flooding so many cities are scrambling to take proactive measures to cool their streets down and protect people from the dangerous impacts of overheating. In urban heat islands, temperatures can be up to 20 degrees Fahrenheit hotter than less populated areas. Austin, TX has a climate resilience plan that includes strengthening emergency response and future-proofing new facilities and infrastructure. It also developed an urban forest canopy for the city to ensure cool outdoor spaces. The city has now applied for a United States Department of Agriculture (USDA) grant to plant more trees after finding the tree canopy coverage was helping Austin to adapt to hotter temperatures. In 2021, San Antonio became the first city in Texas to participate in a pilot project to lower pavement temperatures by applying a coat of paint that reflects the sun's rays. I was disappointed that other large cities in Texas (like Dallas and Houston) were not mentioned in the article. My impression of Dallas is that there is a lot of concrete.

Detecting spoiled foods with LEDs – A potential improvement in non-invasive monitoring of fruit and vegetable freshness.

Joshua trees are dying. This new legislation hopes to tackle that – A compromise law…sets up a conservation fund and requires the state to develop a conservation plan and companies to obtain a permit from the state to cut down or relocate existing trees.

The looming 840,000 ton waste problem that isn't single-use plastics – Carbon and glass fiber composites used in wind turbine blades, hydrogen tanks, airplanes, yachts, construction, and car manufacturing. "This is a huge opportunity," said Dr Wei. "And not only because various modes of recycling are cost-effective and minimally impactful on the environment. In an era of mounting supply chain disruptions, local recycled products can provide a more immediate product when compared to imports and create a burgeoning advanced manufacturing industry."

National Park Visitors Warned to Be "Prepared to Survive" Heat – My husband and I have avoided trips to the western national parks in summer since the 1980s…primarily to avoid crowds but now ‘excessive heat’ is part of our rationale too.

The ocean's color is changing as a consequence of climate change – The color shifts have occurred in 56% of the world’s ocean based on analysis of data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite, which has been monitoring ocean color for 21 years. Tropical oceans have become steadily greener. Changes in color reflect changes in plankton communities, that will impact everything that feeds on plankton. It will also change how much the ocean will take up carbon, because different types of plankton have different abilities to do that.

Global diet study challenges advice to limit high-fat dairy foods – Some dietary advice is more impactful that others. New studies show that dairy, particularly whole fat, may protect against high blood pressure and metabolic syndrome.

Dust From the Drying Great Salt Lake Is Wreaking Havoc on Utah’s Snow – Dust makes the snow less white…which means it warms more quickly and melts!

Early Medieval Ivory Pocket Ring Analyzed – The ring was found in the grave of a wealthy Anglo-Saxon woman near Sheffield, England…and it was made from the tusk of an African elephant!

Parts of a Munich synagogue demolished by Nazis are found in a river 85 years later – The site of the synagogue is a parking lot and department store now. About 150 tons of stone columns and a tablet bearing the Ten Commandments were found about 7-8 miles from the site in a river. The synagogue had been built in the late 1800s and had more than 1,500 seats. It was destroyed in 1938.

Cosmetic chemical concerns – Not an exhaustive list/explanation, but worth browsing…there are others that seem to be concerning too (such as sulfates) that manufacturers are saying their products are eliminating.

Astro-tourism – chasing eclipses, meteor showers and elusive dark skies from Earth – We did a trek to Nebraska for the 2017 eclipse…have enjoyed Staunton River State Park Chaos Star Parties. My husband has been to Greenbank and Cherry Springs State Park for similar amateur astronomer events. It would be great if there were more such events but there are fewer people interested (and able to afford the equipment) than birders. Hopefully some of the dark sky sites will enlarge their offerings beyond outreach events for individuals that would like places to set up their own equipment. On the plus side – there are solar eclipses come up!

Native Bees Yield Hardier Flowers Than Honey Bees, Research Finds – When pollinated by native bees, plants produce more diverse offspring….and diversity is increasingly important as our climate changes.

Frogs as pollinators – A previously undocumented interaction…and an example that there are still aspects of the natural world to be discovered.

Older adults who remain more active have a better quality of life, study finds – Not really a new idea…but a study that tried to quantify the impact.

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. Recent studies have shown that:
