Phys.org / Biological pumps: How zooplankton are transporting microplastics to the ocean depths
A new study has, for the first time, recorded and measured just how fast microplastics move through the gut passage of a key zooplankton species in real time—and used those measurements to estimate how much plastic these ...
Phys.org / Vera C. Rubin Observatory spots record-breaking asteroid in pre-survey observations
Astronomers analyzing data from Vera C. Rubin Observatory have discovered the fastest-ever spinning asteroid with a diameter over half a kilometer—a feat uniquely enabled by Rubin. The study provides crucial information ...
Phys.org / Solar physicists discover long-hidden source of gamma rays unleashed by flares
Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most violent eruptions.
Phys.org / Jupiter's moon Europa lacks the undersea activity needed to support life, study suggests
The giant planet Jupiter has nearly 100 known moons, yet none have captured the interest and imagination of astronomers and space scientists quite like Europa, an ice-shrouded world that is thought to possess a vast ocean ...
Phys.org / The US used to be really dirty: Environmental cleanup laws have made a huge difference
Growing up in the 1970s, I took for granted the trash piles along the highway, tires washed up on beaches, and smog fouling city air. The famed "Crying Indian" commercial of 1971 became a symbol of widespread environmental ...
Phys.org / North Pacific winter storm tracks shifting poleward much faster than predicted
Alaska's glaciers are melting at an accelerating pace, losing roughly 60 billion tons of ice each year. About 4,000 kilometers to the south, in California and Nevada, records for heat and dryness are being shattered, creating ...
Phys.org / EPA says it will propose drinking water limit for perchlorate, but only because court ordered it
The Environmental Protection Agency on Monday said it would propose a drinking water limit for perchlorate, a harmful chemical in rockets and other explosives, but also said doing so wouldn't significantly benefit public ...
Phys.org / Taste buds: From flavor explosions to muted meals—why our taste changes as we age
Ever bitten into a hot pie, yelped "Hothothot!" then had your taste buds go on strike for the next week? Taste buds are a sensitive bunch.
Phys.org / Optics research uses dim light to produce bright LEDs
Researchers at Princeton and North Carolina State University have developed a technique that substantially improves the ability to convert low-energy light into a high-energy version. The method has immediate applications ...
Phys.org / Plasma rings around M dwarf stars offer new clues to planetary habitability
How does a star affect the makeup of its planets? And what does this mean for the habitability of distant worlds? Carnegie's Luke Bouma is exploring a new way to probe this critical question—using naturally occurring space ...
Phys.org / New evidence for a particle system that 'remembers' its previous quantum states
In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of chemical reactions to producing highly reliable weather forecasts. For now, however, they remain extremely ...
Tech Xplore / Solar hydrogen can now be produced efficiently, no platinum required
A research team led by Chalmers University of Technology, Sweden, has presented a new way to produce hydrogen gas without the scarce and expensive metal platinum. Using sunlight, water and tiny particles of electrically conductive ...
