Gleanings of the Week Ending January 24, 2026

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.

1/3/2026 The Scientist Polio Vaccine History: The Shot That Saved Millions - On April 12, 1955, when the Salk polio vaccine was declared “safe and effective,” church bells rang out, kids were let out of school, and headlines around the world celebrated the victory over polio. When asked whether he was going to patent the vaccine, Salk told journalist Edward R. Murrow it belonged to the people and would be like “patenting the sun.”

1/8/2026 Smithsonian Magazine Hundreds of Flowering Species Bloomed Across Britain and Ireland Last Winter - Citizen scientists in the British Isles documented more than 300 native plant species blooming in early 2025, a phenomenon likely caused by climate change. While it’s lovely to see so many wildflowers in bloom … it’s also a sad reflection of the way our climate is changing and the knock-on effects this might have for all the wildlife—bees and other pollinators, butterflies and all the larger creatures further up the food chain—that depend on plants. If flowering times are increasingly out of sync with insect hatching times, the consequences could be very serious.

1/8/206 People in Brazil are living past 110 and scientists want to know why – Brazil’s highly diverse population harbors millions of genetic variants missing from standard datasets, including rare changes linked to immune strength and cellular maintenance. Brazilian supercentenarians often remain mentally sharp, survive serious infections, and come from families where multiple members live past 100. Together, they reveal aging not as inevitable decline, but as a form of biological resilience.

1/7/2026 The Conversation Surprising number of foods contain microplastics. Here’s how to reduce the amount you consume - While eliminating plastics entirely from our diets may be impossible, making these swaps should help to reduce your exposure.

1/6/2026 Nature Defossilize our chemical world - Achieving net zero means eliminating fossil fuels, not carbon — the chemical element has a crucial part to play in powering the modern world. Defossilization means finding sustainable ways to make carbon-based chemicals. Alternative sources of carbon include the atmosphere and plants, as well as carbon in existing biological or industrial waste, such as used plastics or agricultural residue. In some cases, these chemicals will eventually return carbon dioxide to the atmosphere through burning or biodegradation. In principle, this will occur as part of a circular process, rather than one that has added greenhouse gases.

1/5/2026 Planetizen The Child Population in These Cities is Dropping Fast - The proportion of young children in western U.S. metros is falling faster than in other parts of the country. Lower birth rates can sometimes ease immediate pressure on housing and schools but also lead to challenges in supporting economic growth and elder care, as the ratio of working adults to retirees declines.

1/4/2026 Washington Post What we learned about microplastics in 2025 - For many scientists, 2025 was the year of microplastics. It’s only in the past year or so that we have begun to understand that the tiny plastics — including some that are impossible to see with the naked eye — are in our bodies and food as well.

1/9/2026 Science Alert Study Finds Microplastics Are Widespread in Popular Seafoods - In the Pacific Northwest – a region of North America renowned for its seafood – researchers have found particles from our waste and pollution swimming in the edible tissue of just about every fish and shellfish they collected.

12/18/2025 Yale Environment 360 After Ruining a Treasured Water Resource, Iran Is Drying Up - Iran is looking to relocate the nation’s capital because of severe water shortages that make Tehran unsustainable. Experts say the crisis was caused by years of ill-conceived dam projects and overpumping that destroyed a centuries-old system for tapping underground reserves. 

1/8/2026 BBC The animals saved in Greece's ancient accidental 'arks' - Shielded from development and agriculture, many archaeological sites have now become inadvertent safe harbors for plants and animals. In Italy, rare orchids flower around an Etruscan necropolis. In the ancient Greek religious centre of Delphi, researchers found what they believe is a new species of snail – just 2mm (0.08in) long – suspected to live only in that area. In recent years, two new species of lizard were identified in Machu Picchu that may have once had a wider range and today enjoy the relatively undisturbed conditions of the ancient sanctuary. To better understand the connection between historical sites and nature, in 2022 the Greek government launched the Biodiversity in Archaeological Sites research project. Over two years, 49 specialists in all kinds of plants and animals surveyed 20 archaeological sites that spanned Greek history.
