Gleanings of the Week Ending April 18, 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.

4/2/2026 NPR EPA flags microplastics, pharmaceuticals as contaminants in drinking water – A good move….but not enough, by itself, to do what needs to be done to improve water quality. It seems out of step with what the EPA has been doing recently so I am skeptical.

4/2/2026 Science Daily Study finds dangerous lead levels in children’s clothing - Researchers testing children’s shirts from multiple retailers found every sample exceeded U.S. safety limits, raising concerns about toxic exposure—especially since young kids often chew on clothing. Brightly colored fabrics like red and yellow showed particularly high levels, likely due to chemicals used to fix dyes. Simulations suggest that even brief mouthing could expose children to unsafe amounts of lead, a substance known to harm brain development and behavior. None of the items tested met U.S. safety standards.

4/2/2026 National Parks Traveler Seventy-Three Percent of Marine Protected Areas Are Polluted by Sewage - A study by the Wildlife Conservation Society and the University of Queensland (attached) found that nearly three out of four of the world's marine protected areas (MPAs) are polluted by sewage. In the ocean regions most critical for coral reefs and tropical sea life, the problem is even worse: between 87 percent and 92 percent of protected areas are affected, and typical pollution levels inside these zones are ten times higher than in surrounding unprotected waters. Over 16,000 MPAs globally were evaluated in the study.

4/1/2026 Clean Technica U.S. Coal Exports Decreased in 2025 after 4 Years of Growth - The decrease in U.S. coal exports largely reflects a 92% decrease in exports to China in 2025 compared with 2024, after China imposed a 15% additional tariff on imports of U.S. coal in February of last year and a 34% reciprocal tariff on imports from the United States in April. It also reflects a global market characterized by ample supply and soft demand, which caused prices to decline, making it increasingly difficult for U.S. coal exporters to earn profits. Finally, coal generation in the U.S. domestic coal market rose 13% in 2025, leading to a 12% increase in electric power coal consumption after three straight years of decreases.

3/9/2026 The Scientist Nearly Ten Percent of Cancer Papers Flagged as Potentially Fake - Over the last two decades, the scientific literature has been flooded by low-quality research papers produced by for-profit organizations known as paper mills. It is estimated that suspected paper mill products account for two to 46 percent of manuscripts submitted to scientific journals, with the estimated rate of problematic articles in biomedical research reaching nearly six percent in 2023.

4/1/2026 Smithsonian Magazine Humans Might Struggle to Make Babies in Space. Sperm Gets Disoriented in Microgravity - Many of the proteins found on sperm act as mechanosensors, tiny molecular devices that detect physical forces. Remove the force of gravity, and it stands to reason that these sensors would be thrown off, disrupting the sperm’s ability to orient and navigate. As we progress toward becoming a spacefaring or multi-planetary species, understanding how microgravity affects the earliest stages of reproduction is critical.

4/1/2026 National Parks Traveler Study Finds Microplastics on 45 Percent of Beaches - A 2025 study collected samples from 209 beaches across 39 countries and 6 ocean basins, discovering that 45 percent of the beaches contained “suspected microplastics” (those visually identified but not yet confirmed through further analysis). Some of the samples came from Padre Island National Seashore in Texas, where microplastics may indirectly reduce the turtle nesting success of species like the endangered Kemp’s ridley sea turtle.

4/1/2026 NPR The oil industry is betting big on plastics. Here's what that means for the future - Beth Gardiner, a journalist and author of the new book "Plastic Inc.: The Secret History And Shocking Future Of Big Oil's Biggest Bet." In it, she argues that while millions of us have been trying to use less plastic, the fossil fuel industry has been making more. Plasticis Big Oil's plan B. The less we use, the more they make.

4/20/2026 Smithsonian Magazine This High School Student Invented a Filter That Eliminates 96 Percent of Microplastics from Drinking Water - Her current prototype, which is about the size of a standard bag of flour, consists of three modules. The first unit, about a liter in volume, holds the contaminated water inside it, while the second stores the magnetic oil-based ferrofluid. The core process takes place in the third module, which is much smaller. A magnetic field pulls the microplastics out of the water, and the ferrofluid is recovered and reused in a closed loop. --- I hope there is follow-up to this story!

3/30/2026 CNN Millions of preterm births and thousands of infant deaths linked to plastic chemical - Two chemicals used to make plastic more flexible are linked to nearly 2 million premature births and the deaths of 74,000 newborns worldwide in 2018, according to a new study. Babies who survive may have breathing problems, feeding difficulties, cerebral palsy, developmental delay, vision problems, and hearing problems. he two chemicals in the study — Di-2-ethylhexylphthalate, or DEHP, and its cousin diisononyl phthalate, or DiNP — are part of a family of synthetic chemicals called phthalates. Meaningful protection cannot rely solely on individual behavior. The most effective solutions are upstream, including stronger regulations, safer product formulations, better labeling, and improved environmental management and regulatory oversight.
