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.

2/2/2026 York Daily Record Mountains of plastic turf in limbo after Pa. recycling project falters - A Danish company's plan to build an artificial turf recycling plant in Pennsylvania has failed due to bankruptcy. The state is now responsible for cleaning up thousands of tons of abandoned turf stockpiled across three counties. The abandoned turf, which may contain "forever chemicals," will now be sent to a landfill instead of being recycled.

2/8/2026 Clean Technica Why China’s Aluminum Industry May Have Reached Peak CO2 - Relocation to hydro regions is largely complete. Secondary aluminum is rising into double digit millions of tons. Coal heavy output has already peaked and begun to edge down. Renewable penetration in coal regions continues to rise. Reversing this trend would require renewed growth in coal-based smelting or a collapse in recycling, neither of which fits China’s industrial or energy trajectory.

2/9/2026 BBC Fungi mining and giant waste piles: How to get rare earths without mining rock -Gigantic heaps of coal ash, mine tailings and red mud are traditionally expensive and difficult to deal with. But if new processes allow rare earth harvesters to engage in remediation while hoovering up rare earths, then industry and environmentalists might no longer be at odds over what to do about all that waste.

2/8/2026 Science Daily Scientists finally solve a 100-year-old mystery in the air we breathe - The new model offers a stronger foundation for understanding how airborne irregularly shaped nanoparticles (like soot, microplastics, viruses) move across a wide range of scientific fields. These include air quality monitoring, climate modeling, nanotechnology, and medicine. The approach could improve predictions of how pollution spreads through cities, how wildfire smoke or volcanic ash travels through the atmosphere, and how engineered nanoparticles behave in industrial and medical applications.

2/6/2026 Archaeology Magazine Aqueduct at Early Italian Villa Explored - Based on the construction method of this hydraulic system, it might have been originally created to serve a rural village predating the construction of the villa, during a period before the Romans had fully solidified their control over this region of Italy.

2/4/2026 Yale Environment 360 Seas to Rise Around the World — but Not in Greenland - The reasons are twofold. 1)  the massive Greenland ice sheet, which at its center is roughly a mile thick, compresses the land underneath. As the ice melts, the land rebounds, rising above the sea. 2) the Greenland ice sheet is so large that it exerts a gravitational pull on surrounding waters, drawing them higher. But in a warming Arctic, Greenland is shedding some 200 billion tons of ice a year. As its gravitational pull wanes, waters recede.

2/5/2026 Smithsonian Magazine Air Pollution Can Cause Some Ants to Turn on One Another—and Neglect Their Young - As insect populations decline around the world, the findings further point to air pollutants as a possible cause, in addition to pesticides, light pollution and other factors. The work is especially important given the crucial role ants play in maintaining healthy habitats, such as dispersing seeds, controlling pests and aerating soil.

2/4/2025 Cool Green Science Reading the Tree Rings – Great photographs by Greg Kahn for this article. One of the labs visited for the article was the Laboratory of Tree-Ring Research at the University of Arizona that I visited when my daughter was a graduate student in Tucson in 2015 (my blog post about it here).

2/4/2026 Compound Interest World Cancer Day: How antibody–drug conjugates for cancer work - Our ability to use medicines to target more effectively is improving, and antibody–drug conjugates are an increasingly effective tool in combating cancers. This graphic explains what they are, how they work, and how they might improve in the future.

2/4/2026 National Parks Traveler Florida’s Ailing Reef - The reef is fighting for its very survival, beset by the trauma of climate change and warming water, commercial and recreational fishing, and drainage pollution coming from Florida’s canal system.

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.

Antarctic 'greening' at dramatic rate - Vegetation cover across the Antarctic Peninsula has increased more than tenfold over the last four decades… fundamental changes to the biology and landscape of this iconic and vulnerable region.

Is cleaning with baking soda better for the environment? – Maybe not…and it might not be very good at some types of cleaning either.

Meet Milagra, a Rare Condor Rescued as an Egg and Newly Released Back into the Wild – A success at Arizona’s Vermilion Cliffs National Monument.

Landslides, Thousands Of Downed Trees, Undercut Roads Along Blue Ridge Parkway – Lots of repairs for the National Park Service after Hurricane Helene. Some damage is severe enough (i.e. more than just clearing mudslides and debris) that it will take time to repair. The fall foliage will come and go.

In Search of Microbes That Weave Colors into Moroccan Carpets - A scientist’s quest for microbes that produce purple pigments led to the vibrant world of natural dyes for women in the Atlas Mountain region of Morocco creating sought after traditional woven carpets…it’s a great intersection of biology and traditional artistry! The findings are compiled into a 48-page open-source guidebook, also translated into English, which described their project, introduced microbial dyeing, and catalogued recipes for plant dyes.

Dementia diagnostic markers change with time of day - Biomarker levels (p-tau217) were at their lowest in the morning when participants woke and highest in the evening.

Great Lakes Water Quality Project Seeks to Restore Coastal Vegetation - Returning certain croplands to perennial vegetation to reduce runoff and limit erosion.

'A warmer, sicker world': Mosquitoes carrying deadly diseases are on an unstoppable march across the US - West Nile virus, Eastern equine encephalitis (EEE), malaria and dengue…The mosquitoes that carry these diseases are thriving in a warming world.

Extinct Volcanoes Could Be Source of Key Metals Needed for Clean Tech - Rare-earths lurking under extinct volcanoes may be easier to extract. The iron-rich magma that formed some extinct volcanoes would be up to 100 times more efficient at concentrating rare-earths than the magma found in active volcanoes today. By one estimate, demand for rare-earths is set to grow fivefold by the end of this decade so finding them closer to home could contribute to more rapid conversion to clean technologies.

See Newly Discovered Nazca Drawings That Depict Llamas, Human Sacrifices and More - With the help of artificial intelligence, researchers have found hundreds of ancient artworks carved into the pebbled ground of Peru’s Nazca Desert in 6 months compared to 430 found between 1927 up to before the use of AI.
