3/8/2026 Our World in Data What are the world’s deadliest animals, and can we protect ourselves against them? – Mosquitoes and snakes top the list! In many regions, deaths from mosquitoes have decreased dramatically. Malaria was once prevalent in countries that are now free of it. If we could achieve this in all parts of the world, the number of deaths caused by other animals would be almost six times smaller. If we were to also eliminate deaths from snakes with antivenoms and better diagnostics, the death toll would be again reduced by almost two-thirds.

3/8/2026 Science Daily Scientists stunned to find signs of ancient life in a place no one expected - Chemosynthetic microbes—organisms powered by chemical reactions—creating the mats in the dark depths of an ancient ocean.

2/24/2026 BBC 'It seemed to defy the laws of physics': The everlasting 'memory crystals' that could slash data center emissions -Silica and DNA are "very attractive from a sustainability perspective", acknowledges Tania Malik, assistant professor at the School of Informatics and Cybersecurity at Technological University Dublin in Ireland. "However, these technologies are unlikely to replace conventional storage for everyday computing or AI workloads anytime soon."

2/11/2026 The Scientist Oak Trees’ Drought Resilience is Rooted in Microbes - Oak trees maintained relatively stable microbial communities with subtle shifts in response to drought stress. They observed an increased abundance of Actinobacteriota, which are linked to drought tolerance, and other bacterial and fungal genera, suggesting that the oak trees can recruit beneficial organisms under stressful conditions. These changes could help researchers identify additional bacterial biomarkers as trees adapt to climate change.

3/9/2026 Compound Interest International Women’s Day: Twelve women from chemistry history – 12 women chemists from around the world.

3/8/2026 National Parks Traveler North Kaibab Trail at Grand Canyon National Park Seriously Damaged by Debris Flows - Debris flows in the wake of the Dragon Bravo fire at Grand Canyon National Park last year heavily damaged sections of the North Kaibab Trail, which will require some significant rebuilding in places this spring.

3/6/2026 Clean Technica It’s Time for an Authentic Golden Age of Agriculture - Contemporary industrial agriculture is less about producing food and more about generating animal feed, biofuels, and industrial ingredients for processed food products. Frank Carini of ecoRINews argues that producing more local food requires a series of changes. He offers a series of steps:

• Stop taking farmland out of production;

• Provide better financial support to local and regional farmers;

• Increase funding for federal extension services;

• Approve more bond money for farmland protection;

• Attract young farmers to the profession;

• Make farmland affordable; and,

• Use the land we do have with our future in mind.

3/6/2026 Planetizen Hundreds of Vacant NYC Public Housing Units ‘Taken Over’ by Squatters –Vacancies often result from the need to make extensive renovations before units can be leased out when a prior tenant leaves. That frequently includes costly lead paint and asbestos abatement—required by local law and under NYCHA’s federal monitorship—work which takes an average of four to six months to complete, officials have said. In general, it takes the housing authority an average of 326 days to “turnaround” a vacant apartment for new occupancy, according to the most recent public data.

3/5/2026 Smithsonian Magazine See the New U.S. Postage Stamp Honoring the Bison, America’s National Mammal – A stamp within a stamp design.

3/4/2026 The Conversation Pollution, noise and climate stress all pose a serious threat to heart health - In an unprecedented collaboration, the European Society of Cardiology, the American College of Cardiology, the American Heart Association and the World Heart Federation have issued a joint statement calling for immediate action against environmental stressors – pollution, noise, climate stress – to reduce cardiovascular mortality. The question is no longer whether pollution causes cardiovascular disease, but how much additional harm we are willing to accept knowing that it is, to a large extent, preventable.

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.

How extreme weather is making plastic pollution more mobile, more persistent and more hazardous - Rising temperatures, humidity and sunlight break plastic down, making it brittle and cracked, accelerating its disintegration into tiny fragments. A 10-degree Celsius (18 Fahrenheit) rise in temperature during an extreme heat wave could double the rate at which plastic degrades. Extreme storms, flooding and wind also hasten the breakdown of plastic, mobilize it and spread it more widely. Flooding can also help forge “plastic rocks,” created when rocks and plastics form a chemical bond and merge together. These become hotspots for microplastic generation. Wildfires release microplastics and highly toxic compounds into the atmosphere. Global annual production of plastic increased 200-fold between 1950 and 2023 and is predicted to keep increasing as the world moves toward clean energy and oil companies shift investments to plastics.

YMCA: The Swan Song of SROs and the Birth of Modern Homelessness - Single room occupancy hotels played a central role in America’s affordable housing ecosystem for decades, providing cheap, flexible accommodations without government subsidy. They are effectively large-scale boarding houses, offering small private rooms or dorm-style quarters with shared bathrooms and minimal kitchen facilities. The YMCA was the nation’s largest SRO provider, with more than 100,000 units nationwide at its peak. SROs were far from ideal, but without this form of housing or any other low-cost option, homelessness was the inevitable result. It was just as Edith Elmer Wood feared back in 1919: Housing reform had created a housing famine.

Recycling Lead-Acid Batteries Has Significant Health Risks - What happens to the old ones when they are no longer serviceable? They get melted down to recover the lead in them, which can then be used to make new batteries. In the US, that work often gets outsourced to other countries. It’s a patchwork of shoddy factories in places like Ghana, Nigeria and Tanzania providing more lead for new car batteries….and where people die from lead poisoning. Car companies look the other way.

More Than 1,200 Marine Animal Species Eat Plastic. Ingesting Even a Tiny Amount Can Kill Them - Data from more than 10,000 marine animal autopsies. About half of the examined sea turtles, one-third of seabirds and one in eight marine mammals had plastics in their stomachs. The study didn’t examine other ways plastics can hurt wildlife, such as strangulation, malnutrition or toxic effects. It also didn’t look at the harms of tinier pieces of plastics—microplastics—which have been found in the deep ocean and can also affect marine life. Researchers say the best way to protect wildlife from plastic is to reduce the amount of it that enters the ocean, namely through local and national policy.

The Forgotten Roman Ruins of the ‘Pompeii of the Middle East’ – Jerash – ruins near Amman, the capital of Jordan and the country’s second most popular tourist destination after Petra. After spending more than a millennium covered by sand, Jerash has reclaimed its place as a cornerstone of both Western and Middle Eastern civilization.

Just ten species make up almost half the weight of all wild mammals on Earth – Deer and boars account for almost half the biomass of wild land animals.

New research reveals what’s really hiding in bottled water - Each sip may contain invisible microplastics that can slip through the body’s defenses and lodge in vital organs. These tiny pollutants are linked to inflammation, hormonal disruption, and even neurological damage, yet remain dangerously understudied. “People need to understand that the issue is not acute toxicity -- it is chronic toxicity.”

Beavers are Dam Good for Biodiversity, Bringing Bats, Butterflies and Other Critters to Their Neighborhoods - Beavers are famous for being ecosystem engineers, capable of transforming once-dry landscapes into lush, green wetlands that support many other land- and water-dwelling species. Now, two new studies suggest these benefits also extend to creatures who spend much of their time in the air like bats and pollinator insects.

This tiny pill could change how we diagnose gut health - Tiny ingestible spheres filled with engineered bacteria can detect intestinal bleeding by glowing when they encounter heme. Early tests in mice suggest they could become a quick, noninvasive way to monitor gut disease. The work was done by the NSF of China and other sources in China. Will China now dominate this type of research with the funding cuts in the US?

Meet the 7 Swans a-Swimming – There are 7 swan species in the world…which fits very well with The Twelve Days of Christmas.

Homeless in America (1988 eBook)

The opening message of this book concluded by saying ‘We must not let homelessness become an American institution.’ And yet – in 2025, there are still a lot of people that are homeless and the cost of housing is rising fast enough that it is unlikely that there will ever be enough affordable housing….or effective enough attention to reduce the tragedies that unfold for people that find themselves in the situation.

The book is a pictorial work – full of photographs from cities all over America. Some of the people had died before the book was published. It is available on Internet Archive. I found myself thinking about what has changed. There are new drugs that are, at least, as addictive as the ones in 1988 and some are more likely to cause death from overdose or wounds that will never heal. The tents are similar. The cars that people try to live in are different models…probably just as uncomfortable. But in the end – the efforts that non-profits and churches and cities made really have not been very effective.
