Phys.org / Removing yellow stains from fabric with blue light
Sweat and food stains can ruin your favorite clothes. But bleaching agents such as hydrogen peroxide or dry-cleaning solvents that remove stains aren't options for all fabrics, especially delicate ones. Now, researchers in ...
Phys.org / 'Greetings from 51 Pegasi b': How NASA made exoplanets into tourist destinations
Looking for the perfect vacation? Do you crave late-night fun? PSO J318.5−22, the planet with no star where nightlife never ends, is perfect for you! Prefer some peace and a chance to catch some rays? Kepler-16b, the land ...
Phys.org / Deforestation reduces rainfall by 74% and increases temperatures by 16% in Amazon during dry season, study says
Deforestation in the Brazilian Amazon is responsible for approximately 74.5% of the reduction in rainfall and 16.5% of the temperature increase in the biome during the dry season. For the first time, researchers have quantified ...
Phys.org / The ocean carbon sink is ailing: 10% drop in CO₂ absorption seen during record 2023 marine heat wave
Measurements analyzed by an international research team led by ETH Zurich show that the global ocean absorbed significantly less CO₂ than anticipated during the unprecedented marine heat wave in 2023.
Phys.org / Unlocking how bacteria bounce back after antibiotics
A study by researchers from Wuhan University, York University (UK) and Peking University has uncovered how Escherichia coli (E. coli) persister bacteria survive antibiotics by protecting their genetic instructions.
Phys.org / How Amazon trees use recent rainfall in the dry season and support the production of their own rain
The Amazon is the world's largest tropical forest, home to unmatched biodiversity and one of the planet's longest rivers. Besides the Amazon River, the Amazon rainforest also features "flying rivers:" invisible streams of ...
Phys.org / Cities face double trouble: Extreme heat and air pollution mean increasing compound weather events
U.S. cities are facing a growing threat that goes beyond hot weather or hazy air. New research from the University of Oklahoma reveals that "compound events"—periods when heat wave conditions coincide with high air pollution ...
Phys.org / The tipping of the last resilient glaciers: Filling in years of missing data from Tajikistan
Too little snowfall is now also shaking the foundations of some of the world's most resilient "water towers," a new study led by the Pellicciotti group at the Institute of Science and Technology Austria (ISTA) shows. After ...
Phys.org / Massive stars in metal-poor environment often have close partners, scientists discover
Massive stars in metal-poor galaxies often have close partners, just like the massive stars in our metal-rich Milky Way. This was discovered by an international team of 70 astronomers led by scientists from Belgium, the Netherlands, ...
Phys.org / Self-assembling magnetic microparticles mimic biological error correction
Everybody makes mistakes. Biology is no different. However, living organisms have certain error-correction mechanisms that enable their biomolecules to assemble and function despite the defective slough that is a natural ...
Phys.org / Global map shows where ocean plastics pose greatest threats
As plastic pollution emerges as one of the planet's most pressing environmental threats, Tulane University scientists have published the first global assessment of where plastics pose the greatest ecological risks to marine ...
Phys.org / Bite by bite: How jaws drove fish evolution
If you're reading this sentence, you might have a fish to thank. Fish were the first animals to evolve jaws. They use their jaws primarily to eat, but also for defense, as tools—such as to burrow or to crack open hard food—and ...
