Old Growth – Mitch Epstein photographs of very old trees.

The true story of a famed librarian and the secret she guarded closely – Belle da Costa Greene, the first director of New York's historic Morgan Library and Museum.

Inside Turkey’s Mysterious Ancient City That Once Sheltered Thousands—Underground - The Derinkuyu underground city is a sort of gargantuan anthill, except made by and for humans—up to 20,000 of them at a time, in fact. The city descends 280 feet into the earth, divided into eight levels. Upper levels were primarily used for living and sleeping, while lower levels were used for storage, even housing a dungeon. The far-stretched system of interconnected rooms was carved out of the Cappadocia region’s tuff rock. People didn’t live in these underground quarters year-round, however, as they were mainly used for shelter during times of conflict or extreme weather.

Climate change will affect food production, but here are the things we can do to adapt - Farmers can pick crop varieties best suited to different climate condition...production can shift to places with more optimal temperatures…planting and harvest times can shift as the seasons shift…focusing on the right irrigation, fertilizer, pesticides synchronized to climate change. We have the chance to build a more productive and resilient food system, but it’s not guaranteed that we will. It depends on whether the seeds, irrigation, and adaptation practices will be available. That will require real and sustained investment from governments, donors, and private companies.

Toothbrushes and showerheads covered in viruses ‘unlike anything we’ve seen before’ - We live in a richly microbial world. Interactions with bacteria and other microbes in our homes are an integral part of our human biology.

The monarch butterfly may not be endangered, but its migration is - Migrating monarchs don't fly at night, so they spend their evenings in bunches on trees or shrubs, known as roosts. The study relied on 17 years of data from more than 2,600 citizen scientist observations of monarch roosts along the butterfly's migration route. The researchers found that roost sizes have declined by as much as 80%, with these losses increasing from north to south along the migration route. The evidence shows that when monarchs are reared in a captive environment, either indoors or outdoors, they're not as good at migrating.

World’s Rivers Are Driest They - In 2023, the hottest year on record, the Mississippi River and Amazon River basins were at all-time lows, while the Ganges, Brahmaputra, and Mekong rivers, which all have their headwaters in the Himalayas, were also unusually dry. Across nearly half the globe, rivers were drier than normal.

The worrying puzzle behind the rise in early-onset cancer - Over the past 10 years, rates of colorectal cancer among 25- to 49-year-olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina. Perhaps the most obvious explanation points to the role of obesity and metabolic syndrome, conditions which have been associated with driving cancer risk through increasing inflammation throughout the body and causing the dysregulation of key hormonal pathways. Or maybe changes in sleep patterns is part of the explanation. Combined with shifts in lifestyle, many cancer scientists believe that a key driving force for these illnesses is the consequences of various toxic changes within the gut (from microplastics). Antibiotics might be involved too. The bottom line…it’s a looming public health crisis.

New research reveals how large-scale adoption of electric vehicles can improve air quality and human health - Computer simulations show that aggressive electrification of the U.S. vehicle fleet, coupled with an ambitious rollout of renewable electricity generation, could result in health benefits worth between US$84 billion and 188 billion by 2050. Even scenarios with less aggressive grid decarbonization mostly predicted health benefits running into the tens of billions of dollars.

New study explores how universities can improve student well-being - Six guiding principles for improving student well-being:

  • Embedding well-being into curricula for broader, more accessible adoption.

  • Having each initiative only focus on one or two aspects of well-being, making it easier to create instruction that can also be more immersive.

  • Tailoring initiatives to the student body and university culture.

  • Securing buy-in from faculty.

  • Ensuring new offerings are accessible and don't create additional financial burden for students.

  • Employing an iterative assessment framework at the beginning to make it easier to change or scale up a program.

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.

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.

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.

In 2050, over 800 million people globally estimated to be living with back pain: Analysis also dispels common back pain myth -- ScienceDaily – Attributable to occupational factors, smoking and being overweight. More common among older people and women. Current clinical guidelines for back pain treatment and management do not provide specific recommendations for older people. Low back pain continues to be the greatest cause of disability worldwide.

Why Are Some Wolves Black? The Answer Will Surprise You - Cool Green Science – There are more black-colored wolves in the southern Rocky Mountains…more gray coated wolves everywhere else. The black is from dogs that traveled with humans across the Bering Strait around 10,000 years ago, and those genes also make the black-colored wolves more resistant to distemper (which came with the conquistadors to South America).

We now know exactly what happens in nature when we fell forests -- ScienceDaily – When agriculture replaces forestry…a detailed study done in the Azores…substantiates the advise to plant native trees and flowers…stop mowing the lawn!

The viruses that helped to make you human - BBC Future – About 8% of the human genome comes from viruses but, curiously, there is not evidence of new endogenous retroviruses (ERVs) entering the human genome in the last few 1000 years (Koalas are being invaded by koala retrovirus with the viral DNA found in some populations but not others). The most studied human ERV is HERV-W; first described in 1999; genes that are essential for the placenta to form.

Algae in the Andes – Bursts of phytoplankton are not unusual in oceans, seas, gulfs, and canals. Now they are in lakes too….and potentially hazardous.

New Low Cost High Performance Perovskite Solar Cells – It appears that solar cells are on track to get better and better!

Communities should reconsider walking away from curbside recycling, study shows -- ScienceDaily – Maybe the trend of towns and cities across the US cancelling or scaling back recycling programs due to rising costs needs to keep recycling but focus on recycling materials with the greatest market value (newspaper, cardboard, aluminum/steel cans, HDPE/PET plastic bottles) and highest potential for carbon offset.

Does the roar of rocket launches harm wildlife? These scientists seek answers – Launches at Vandenberg have increased from 5-15 rockets per year to 50-100. There are biodiversity hotspots near launch sites in California, Texas, and Florida; the study at Vandenberg is intended to provide more insight about how launches impact wildlife. The study is funded for 3 years but may need a decade to understand some of the impacts.

Remains of Child Mill Workers Examined in Northern England - Archaeology Magazine – A study of 150 remains from a churchyard cemetery…many were young people between the ages of 8 and 20. They were pauper apprentices and their bones showed signs of stunted growth, malnutrition, rickets, and tuberculosis.

Turmeric: here’s how it actually measures up to health claims – Many of the health claims have only been proved in the lab or in animals. There are studies that show that turmeric has a modest benefit for pain compared to a placebo – but the studies are often on small populations and there is a wide variation in the amount of turmeric participants were given. There is not enough research to firmly support any of the claims…although it is a great spice (flavor and color).

Virologists Identify More Than 5,000 New Viruses in the Ocean – Another indication that we still have a lot to learn about life on our planet.

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!

Germany’s Nature Society Crowns the 2022 Nature Photographer of the Year – The first picture is of a male kestrel. That caught my attention…and then I browsed the rest of the photos.

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.

Why cavemen needed no braces – Our diet and behavior have changed a lot since the stone and hunter/gather stages of our species….and those changes have impacted our jaw (and teeth and air way). There are more health consequences than just crooked teeth. I’ve bought the book (Kindle version) to learn more.

Characteristics that give viruses pandemic potential – An article from The Scientist that is more future oriented. What we are experiencing with COVID-19 is something that could happen again. The article talks about various types of viruses that pose the greatest threats.

Peer into the Past with Photorealistic Portraits of Roman Emperors – Taking historical sculptures and drawings to the next level. The Smithsonian Magazine summary has images of Augustus, Maximus Thrax, Caligula, and Nero….the rest can be viewed in Daniel Voshart’s site.

Amazing Macro Winners of the International Garden Photographer of the Year 2020 – Visual treats. This it the type post that gives me ideas about things to try with my own camera.

1,200-Year-Old Soap Factory Unearthed in Negev Desert – The soap was made from olive oil and the ashes of the saltwort plant. The factory produced enough for export to places like Egypt and other parts of the Arab world.

Low humidity increases COVID-19 risk: Another reason to wear a mask – This finding does not bode well for the winter when many homes and workplaces have much lower humidity because of furnaces.

Top 25 birds of the week: Birds in Pairs – Beautiful birds….I always enjoy looking at the 25 pictures each week.

Hawaiʻian Snails: A Tale of Discovery and Rediscovery – I remember seeing a snail in a planter box at the airport on the big island while I was waiting for my luggage a few years ago…and I dug up the picture I took when this article prompted the memory.

Wolverines Seen Roaming About Mount Rainier National Park – What a boon remotely triggered cameras can be….and then DNA testing of hair to determine relationships!

 Meet the Squad of Mosquito-Eating Species – Birds, dragonflies, newts, aquatic turtles, and bats. We haven’t noticed very many mosquitoes around this year, but we try to replace the water in our bird baths frequently and make sure our gutters are draining properly. Having the birds around our house probably helps…and the turtles at the neighborhood pond do their part.

Unique Activities for Yesterday:

Going to the basement during a storm. Our phones went off with tornado warnings – which is rare in Maryland. We went to the basement. It turned out to be only heavy rain for us (not very windy either); to the east and south of where we live there was a lot of damage with trees/big branches falling and shingles flying.

Cleaning the leaves off the deck. Over the past week we’ve had several fronts come through that have blown leaves and branches onto our deck. They were still wet when I went out to clean up. I dumped the sediment that had accumulated in the bird bath too.

Finding Witches’ Butter. I photographed the fruiting bodies of Witches’ Butter on our deck railing. The deck is over 25 years old and even regular treatment can’t keep it clear for fungus; it is only visible during times when the wood is wet for several days.

I’m more concerned about a window frame that has the same fungus growing. I’m not keen about replacing the window but we might have to consider it.

Scythian Warrior's Genome Analyzed - Archaeology Magazine – Surprise! Discovered in 1988 and assumed to be a young warrior based on the weapons in the grave. DNA revealed it was a girl and was younger than 14 years old.

90 Percent of U.S. Could Be Powered by Renewables by 2035 - Yale E360 – Technically feasible…but do we have the determination as a country to do what we need to do for future generations?

Repetitive negative thinking linked to dementia risk -- ScienceDaily – But can training/therapy to reduce negative thinking reduce the risk? Whether it does or doesn’t – it seems that people who perceive the positives in their lives are more satisfied/happy….so teaching strategies to enhance that kind of thinking is probably worth it.

How Iceland is undoing carbon emissions for good - BBC Future – Examples of how Iceland is pushing the technical envelope for carbon capture even in heavy industry.

What Makes Some People More Resilient Than Others - The New York Times – Tools most common in resilient people: realistic optimism, a moral compass, religious or spiritual beliefs, cognitive and emotional flexibility, social connectedness.

Memory consolidation during REM sleep: Researchers identify neurons responsible for memory consolidation during REM sleep -- ScienceDaily – I remember the babies I’ve known well having frequent REM sleep….they are doing a lot of memory consolidation!

Top 25 birds of the week: Camouflage – They are easy to spot in these zoomed pictures….in the field, their camouflage is highly effective.

Urine test reveals quality of your diet -- and whether it's the best fit for your body – Interesting work. Maybe in the future we’ll get feedback from the toilet about the ‘health’ of our diet as easily as we get feedback about heart rate and sleep quality from wearable devises now.

The Winnowing of the Wilson’s Snipe – A bird that could fit in the camouflage group…but this bird is special – it makes sound with specialized tail feathers!

Unique activities for yesterday:

Three kinds of day lilies. I have three different kinds of day lilies blooming right now. I love having the flowers in my office and something new opening every day!

Ice maker repair. My husband ordered a replacement part for our ice maker once we started having water overflowing the unit and accumulating in the freezer. He’d done some research online and it seemed likely that the new part would fix the problem. It came and after a few days of the box sitting around to decontaminate, we pulled out the refrigerator to install it (using the opportunity to clean the floor too). This is the type of thing we would have called for repair service pre-pandemic. There are areas where we’ve become a lot more resourceful in recent months and I wonder if we’ll continue that trend post-pandemic.

Radio Tracking a Rare Crayfish – Cool Green Science – There are a lot more species of crayfish than I realized…and they have a bigger role in the stream that I assumed.

Mindfulness for middle school students: Focusing awareness on the present moment can enhance academic performance and lower stress levels -- ScienceDaily – I wonder if ‘mindfulness’ is something we need to teach more overtly now than in the past because technology and daily life tends to push us in ‘unmindful’ ways.

Canadian Canola Fields – I looked at this article because the Bugs101 course that I took recently mentioned the canola fields of Canada (for some reason I had never known very much about Canola as a crop). This article provides more history. It has become a cash crop for Canada in recent decades.

There's a Troubling Rise in Colorectal Cancer Among Young Adults | The Scientist Magazine® - Incidence of colon cancer is falling in older people…but becoming more common in people under 50. It has continued to go up over the past decade. In young adults, the cancer is discovered later too…usually stage 3 or 4.

A Northwest Passage Journey Finds Little Ice and Big Changes - Yale E360 – Lots of changes. Grizzly are moving northward…fewer polar bears…salmon far north of where they used to be…lungworm killing muskox…plastic in ice cores.

Researchers Discover New Family of Viruses | The Scientist Magazine® - The new viruses are found in lung biomes of people that had had lung transplants or have periodontal disease….many times the patients are critically ill. But we don’t know yet if the new family of viruses are linked to disease.

Utah's red rock metronome: Seismic readings reveal Castleton Tower's unseen vibrations -- ScienceDaily – On the plus side – it does not appear that climbers of the tower are impacting it…but this work is a baseline and there could be some longer term effects. Wikipedia has some pictures and a short article about Castleton Tower.

Infographic: History of Ancient Hominin Interbreeding | The Scientist Magazine® - Still learning about the hominin tree and how modern humans carry the genetic heritage.

Camera Trap Chronicles: The Pennsylvania Wilds – Cool Green Science – I wonder what I would see coming through my back yard. I know we have deer…and I occasionally see a fox. Maybe racoons. My first though was to put a camera on the bird feeder or the bird bath.

BBC - Future - Is there a worst time of day to get sick? – Circadian rhythms are important to health….and our medical system doesn’t use them to advantage. I remember being concerned when my mother was in the hospital years ago and the lights were very bright day and night. No wonder she had difficulty sleeping!

NASA's Cassini reveals surprises with Titan's lakes -- ScienceDaily – The data from Cassini’s final flyby of Titan in 2017 has revealed that the lakes in its northern hemisphere are more then 300 feet deep and are methane. Lots more science still to come as more analysis of the Cassini data is done.

Could high-flying drones power your home one day? - BBC News – How could this not cause problems with aircraft if it was widespread? Both the drone and the tether could cause problems.
