New biofilm mechanism in Bacillus cereus could reveal vulnerabilities in food poisoning ba

Scientists from the Department of Microbiology at the University of Malaga, who are also members of the Institute of Subtropical and Mediterranean Horticulture "La Mayora" (IHSM), have discovered a previously unknown mechanism that allows the bacterium Bacillus cereus, which is r

One tiny mutation may explain how bat viruses become human threats

Scientists found that one tiny genetic change can completely alter how a coronavirus behaves in different species. Comparing SARS-CoV-2 with a closely related bat-only virus, they showed that a single amino-acid difference affects whether the immune system fights back or gets sup

Study challenges a common belief about vitamin D and sunlight

A study of nearly 300 people across northern Britain found that vitamin D levels often stay low all year in groups most at risk. Surprisingly, summer sunshine did not significantly boost vitamin D levels among older adults or people from minoritized ethnic backgrounds.

New superconducting X-ray detector is up to 1,000 times more sensitive

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin materials, nanostructures, and ul

Early humans were bringing fire into caves 1.8 million years ago

A new study suggests early humans were using fire in South Africa’s Wonderwerk Cave as far back as 1.79 million years ago. Researchers found burned bones deep inside the cave, where natural wildfires could not have reached, indicating that fire was likely carried in and maintaine

Why South Africa’s leopards shrank to half their normal size

A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after

Scientists discover ancient brain cells that help block distractions

Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in mice, the animals became unusua

Scientists discover hidden “footprints of death” that may help viruses spread

Scientists have uncovered a surprising new twist in what happens when cells die. As dying cells break apart, they leave behind tiny “footprints of death” packed with newly discovered particles that help guide the immune system to clean up the remains. But researchers found that i

Five years of aerosol remote sensing in Mindelo—a milestone in atmospheric research in the

For five years now, a distinctive green laser beam has been shining at night up to 30 kilometers (19 miles) above the harbor of the island's capital. It forms part of a high-energy lidar with which the Leibniz Institute for Atmospheric Research (TROPOS) operates continuous aeroso

The universe may be hiding conscious minds stranger than we can imagine

What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth. Drawing on the vastnes

Automated system detects early signs of nanomaterials toxicity

Korea Research Institute of Standards and Science has developed a toxicity assessment system that automatically measures and analyzes the heart rate of Daphnia magna. Capable of processing heart rate data from approximately 150 individuals per hour, the system can assess the toxi

Fair Workweek laws improve work schedules without cutting pay or benefits, according to re

A study examining Fair Workweek laws across five major U.S. jurisdictions finds that labor regulations have made work schedules more predictable for service-sector workers, without triggering wage cuts or benefit reductions. Published in Science Advances, the research titled "Fai
