(Council) Room Bear: Who decides to remove the grizzly bear from the endangered species list?
Credit: CC0 Public Domain Now 50 years old, the Endangered Species Species Act (ESA) was once a rare beacon of bipartisan unification, and was signed into law with almost indifferent political support by President Richard Nixon. The purpose was clear. Protects at-risk species and allows for recovery using the best science available. However, as a case study on the Grizzly…

Water filters with nanoscale channels selectively remove stubborn “eternal chemicals”
Credit: Monash University Traditional water filters struggle to remove smaller PFAS molecules, but the new Monash designed filter changes it. Researchers at Monash University have developed water filter membranes that effectively remove small PFA molecules, overcoming the important challenges faced by traditional water filters. The researchers designed beta-cyclodextrin (βCD)-modified graphene oxide (GO-βCD) membranes using nanoscale channels that selectively retain PFA…

New water micro cleaner is floating to capture and remove microplastics, which is different from the self
A system that captures microplastics from water works in one cycle. Credit: Orlin Velev/NC State University. In a new paper, researchers at North Carolina State University provide proof of concept of a system that actively removes microplastics from water in a single cycle. The findings listed in the Journal Advanced Functional Materials hold the potential for advances in purifying small…

Remove hidden cancer messengers: How extracellular vesicles help spread tumors
This graphic shows paracrine adhesion signaling in small extracellular vesicles. It secretes a protein called galectin-3. This promotes endocytosis so that the vesicles can be absorbed into recipient cells. Credit: Suzuki Kenichi et al. , Gifu University Most cells in the body send out small messengers called extracellular vesicles that carry proteins, lipids, and other biologically active molecules to other…

New carbon-based materials can remove dangerous “eternal chemicals” from the water
Membrane distillation methods can effectively reduce PFAS concentrations by affecting water purification. Credit: Science Tokyo A diverse group of synthetic chemicals, Perfluoroalkyl and polyfluoroalkyl substances (PFAs) are commonly used in numerous products, including semiconductors, fire-steamed foam, heat-resistant, and non-adhesive cooking utensils. PFAs have a prominent resistance to heat, oil, grease, and water due to strong chemical bonds between atoms. However,…

Selective combustion offers an energy-efficient alternative to remove contaminants from industrial processes
This diagram shows the combustion of a small amount of acetylene in a mixture with ethylene. Credit: Greg Stewart/SLAC National Accelerator Research Institute Researchers at the University of Minnesota Twin City have discovered a new method that allows the catalyst to be used to selectively burn a single molecule with a mixture of hydrocarbons, a compound made of hydrogen and…

You can remove space debris using a robot gripper
Credit: NASA/SUNI WILLIAMS The blue tentacle-like arm attached to the Astrobee Free Flying Robot will grab onto the “Capture Cube” in this image from February 4th, 2025. The experimental gripper demonstrated autonomous detection and capture techniques that can be used to remove space debris and service satellites. In low Earth orbit. The Astrobee system was designed and built at NASA’s…

Scientists create “molecular traps” to remove pollutants from water.
Credit: Manchester University Manchester University scientists have developed new materials that help reduce water pollution caused by harmful chemicals such as the remaining drugs and hygiene products. Water pollution is one of the challenges of the growth of modern life. Many daily items, from drugs to cosmetics, leave residues that are completely disassembled after use. These pollutants often destroy the…

Toxic Tire Decontamination: Researchers Demonstrate Ability to Remove Toxic Particles from Used Tires
Evolution of heating performance, product distribution, and morphology in microwave pyrolysis of EOL tires. Credit: Nature Chemical Engineering (2024). DOI: 10.1038/s44286-024-00110-9 Tires are an essential part of daily life. Without these, our vehicles would simply be a mass of assembled parts, convenient to sit on but ineffective at getting us to our destination. While the usefulness of tires is undisputed,…

US finalizes rules to remove lead pipes within 10 years
Credit: Pixabay/CC0 Public Domain President Joe Biden’s administration on Tuesday finalized a rule requiring the nation’s remaining lead pipes to be removed within 10 years. This is a measure aimed at preventing millions of people from being exposed to toxic metals linked to childhood developmental delays. The policy is a cornerstone of the White House’s environmental justice efforts, as traditional…
