Phys.org / A tug-of-war explains a decades-old question about how bacteria swim
Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology's most intensively studied molecular machines.
Medical Xpress / TB harnesses part of immune defense system to cause infection, study finds
Scientists have made a discovery that helps explain why humans and animals are so susceptible to contracting tuberculosis (TB)—and it involves the bacteria harnessing part of the immune system meant to protect against infection.
Tech Xplore / OLED lighting: Corrugated panel design extends longevity and efficiency
The organic light emitting diodes—known widely as OLEDs—that create vibrant smartphone displays could illuminate rooms, but current designs burn out too quickly at the high brightness needed for room lighting. A new approach ...
Medical Xpress / Insurance data can help fill gaps between longer medical trials for patients up against the clock
Randomized clinical trials remain the gold standard for establishing a medication's effects, producing the evidence by which most drugs and interventions in the U.S. are approved.
Phys.org / Pandora, a keen-eyed satellite built to study exoplanets, readies for launch
Pandora, the latest in a long portfolio of University of Arizona's space science missions, has cleared its last major milestone on its journey into space. This week, Pandora—a satellite about the size of fridge—was mounted ...
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 ...
Medical Xpress / Teens use cellphones for an hour a day at school, study finds
U.S. adolescents spend more than one hour per day on smartphones during school hours, with social media accounting for the largest share of use, according to research published in JAMA. The findings have relevance for educators, ...
Phys.org / Eye-opening research: Greenland sharks maintain vision for centuries through DNA repair mechanism
Dorota Skowronska-Krawczyk sits in her office, eyes fixed on the computer monitor in front of her. "You see it move its eye," says the UC Irvine associate professor of physiology and biophysics, pointing to an image of a ...
Phys.org / How quiet galaxies stay quiet: Cool gas feeds black holes in 'red geysers'
Astronomers have long puzzled over how some massive galaxies stop forming stars and remain dormant for billions of years—even when they still contain gas that could, in principle, fuel new stars.
Phys.org / How does glass 'shake' and why does it start flowing when pushed hard enough?
Glassy materials are everywhere, with applications far exceeding windowpanes and drinking glasses. They range from bioactive glasses for bone repair and amorphous pharmaceuticals that boost drug solubility to ultra-pure silica ...
Tech Xplore / Coal tailings could solve United States' need for rare earth elements
Rare earth elements are an easy-to-find, hard-to-refine resource critical for everything from magnets and electronics to batteries and catalysts for chemical reactions. Since the 1980s, a race has been on between the United ...
Tech Xplore / Did that lamp just fold the laundry? Alumni rethink home robotics
When Aaron Tan began his Ph.D. in mechanical and industrial engineering at the University of Toronto in 2019, leading a robotics startup in Silicon Valley was the furthest thing from his mind.
