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 Mysterious Turkish Megaliths That Predate the Pyramids - Göbekli Tepe or “Potbelly Hill” in Turkish…it may be the world’s oldest calendar.

Planes, trains and monster diggers: The vehicles pushing the limits of electric power - BBC Future Planet recently went on a hunt for some of the biggest electric vehicles in the world – by size and weight. There is no shortage of impressive examples, from giant mining machines to trains and cargo ships. Often the largest excavators are connected to an electric power source by a cable, rather than using an on-board battery. But in terms of weight, heavy goods vehicles are among the largest EVs you might find yourself sharing the road with. Volvo's FH Electric truck, if you include its double trailer and load, is among contenders for the heaviest battery-powered electric road vehicle. Though research suggests we might one day see electric passenger aircraft capable of carrying as many as 90 people. The biggest electric planes today can accommodate a maximum of around nine passengers. The most powerful electric train in the world is perhaps the Shen24 in China. It is capable of carrying more than 10,000 tons – of coal – at up to 120km/h (75 mph).

Maine! Ghost Flower, the inside view – I’ve seen Ghost flowers a few times…but never the inside of the flower.

Crested Rats & Hairy Porcupines: Meet 7 of the World’s Coolest Rodents – The only one of the 7 I’ve seen is the Capybara (at the Dickerson Park Zoo in Springfield, MO).

A photographer captures life in America’s last remaining old-growth forests – What a great project photographer David Herasimtschuk had undertaken!

Plankton mark seasons in the sea, just like leaves and flowers on land – The seasonal flux of phytoplankton and zooplankton. The photo of diatoms (algae) in this post was what caught my attention; I’ve always enjoyed finding them in water samples.

14 Extraordinary Highly Commended Photos From the 2024 Wildlife Photographer of the Year Contest – My favorite was “Leaving the Nest” …two tawny owlets.

The Ancient Temple Carved Out of a Single Rock - Kailasa Cave, one of 34 in the Ellora Caves complex that has been cut and dug from the basalt rock of the Deccan plateau. 100 feet high and 300 feet long would make it the world’s largest—with all four sides liberated and sculpted into pavilions, halls, vestibules, towers, and courtyards by 800 hardy monks over 150 years beginning in the 7th century BCE. It was once painted white to mimic the Himalayan peak.

Thracian horseman’s grave unearthed in Bulgaria - The man was buried wearing clothing decorated with gold appliqués. A gold necklace, a gold diadem, a gold ring, and a knife decorated with gold and semiprecious stones were recovered from the burial, in addition to the remains of a horse and full battle gear, including a breastplate, sword, scabbard, and other knives and spears

Microplastics Found in Human Brains - The brains of people who suffered from dementia contained significantly more plastic than the brains of healthy people. Troublingly, the new study found more plastic in brain samples gathered in 2024 than in samples gathered in 2016.

How Storm King Art Center Became One of World’s Top Sculpture Parks – Adding to my list to consider seeing if I travel to New York (state).

Dirt Cheap Batteries Enable Megawatt-Scale Charging Without Big Grid Upgrades Right Away – Hope the technology trend continues…that this idea helps us transition to more electric trucks and other vehicles.

Extreme Birding: Shorebirds at the Sewage Lagoon – Maybe a great place for birding….if you can stand the smell. The same thing happens at landfills.

The human brain has been shrinking – and no-one quite knows why - The brains of modern humans are around 13% smaller than those of Homo sapiens who lived 100,000 years ago. Exactly why is still puzzling researchers. I was a little surprised that the authors did NOT consider the challenge of birthing babies with larger heads (i.e. until C-sections allowed mother and baby to survive if the baby’s head was too large, both mother and baby died) which would result in natural selection of genes for smaller heads.

Climate change is most prominent threat to pollinators - Pollinator populations are declining worldwide and 85% of flowering plant species and 87 of the leading global crops rely on pollinators for seed production. The decline of pollinators seriously impacts biodiversity conservation, reduces crop yield, and threatens food security. Changes in water and temperature associated with climate change can lower the quantity and quality of resources available to pollinators, decrease the survival of larvae or adults, and modify suitable habitats.

The deep ocean photographer that captured a 'living fossil' – In 2010, Laurent Ballesta was the first diver to photograph a living coelacanth. In 2013, Ballesta and his team returned and encountered multiple coelacanths, spending up to half an hour in their presence. Thanks to Ballesta's work, we now know the coelacanth is among the longest-living fish species, with a lifespan of around 100 years, and has one of the slowest life histories of all marine fish – so, like deep-sea sharks with a reduced metabolism, the coelacanth grows slowly, taking as long as 69 years to reach sexual maturity, and with a gestation period of around five years.

Under stress, an observer is more likely to help the victim than to punish the perpetrator - It takes more cognitive effort to punish others than it does to help them. Studies show that when witnessing an act of injustice while stressed, people tend to behave selflessly, preferring to help the victim than to punish the offender.

Stunning Aerial Photos Capture the Abstract Beauty of Iceland’s Glacier Rivers – Iceland….blue.

These tricks make wind farms more bird-friendly – Migratory birds can crash into wind turbines…but there are ways to reduce the carnage: adding high visibility reflectors and spirals to cables, not building wind farms in flight paths, painting one blade on each turbine black (or stripes of black on each blade), and sound.

Swarms of miniature robots clean up microplastics and microbes, simultaneously – Interesting idea. While the bots were decontaminated and reused…they were not as effective…so more work is needed.

Avi Kwa Ame, Sacred Land in Nevada, to Be Preserved as a National Monument – Good! Another place to see when we make a trip in the west.

Volvo Delivers Its 1st Electric Heavy-Duty Truck in Africa – The truck is being used for collecting waste in Rabat, Morocco. Morocco is also home to the world’s biggest concentrated solar power facility.

A 90-year-old tortoise named Mr. Pickles just became a father of 3. It's a big 'dill' – Radiated tortoise native to Madagascar and critically endangered…at the Houston Zoo.

One of Europe’s last free-flowing rivers declared a National Park – Albania’s Vjosa River. Europe is also removing dams along other river just as we are in the US…but rivers that have been controlled by barriers will never be the way they were before the dam.

Clinics on wheels bring doctors and dentists to health care deserts – It’s a step forward and might work well for preventative or chronic care…but what happens in cases where the need is more urgent…like broken bones, having a baby, the aftermath of a car accident?

Technology over the long run: zoom out to see how dramatically the world can change within a lifetime – A graphic from ‘Our World in Data’ – worth the look. See the big developments they selected occuring during your lifetime….and when technologies we take for granted came along.

Take a Virtual Tour of the ‘Doomsday’ Seed Vault – Its doors are only opened a few times each year for new seed entries. The seeds come from countries from all over the world and are kept at -18 degrees Celsius. The most recent withdrawal was to re-establish a seedbank that had been destroyed in Aleppo during the Syrian Civil War.

Urban Trees Could Cut Summer Heat Deaths by a Third – Increasing tree cover to 30% could reduce premature deaths from urban heat islands by 40%. Sounds like a good idea of heath…and makes the cities more appealing too. Other actions can help too: green roofs/walls, light colored roofs/walls/landscape pavers, and replacing impervious surfaces with plants and soils.

Fresh produce contaminated with toxic BPA-like chemicals found in food labels – A Canadian study found that the chemicals migrate from labels in packaging materials into the food!

Common sweetener suppresses mouse immune system — in high doses – An artificial sweetener (sucralose) that might become a drug to reduce or replace immunosuppressive drugs that often have a lot of unpleasant side effects (if humans react to it the same as mice).
