Phys.org / Eclipse research finds turbulent times in the sun's corona

Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun's outer atmosphere, using one of nature's rarest events as their window: total solar eclipses. Drawing on more than ...

Phys.org / Antibiotic resistance is rising: A membrane protease could be E. coli's weak spot

A University of Alberta research team has identified a new drug target to treat harmful E. coli bacteria—which cause nearly 250,000 deaths a year from urinary tract infections (UTI) and are becoming increasingly resistant ...

Phys.org / The making of doting dads may involve a specific gene

Male caregiving is rare. Of the nearly 6,000 mammalian species, fewer than 5% of fathers stick around to raise their own young. Most are even instinctively hostile. Even among the mammals that pitch in with caregiving duties, ...

Phys.org / An 'electrical' circadian clock balances growth between shoots and roots

Plants don't just respond to light and water, they also run on an internal daily timekeeper known as the circadian clock. Researchers have now discovered that the plant circadian clock can regulate electrochemical signals ...

Phys.org / Cosmic predators: How supermassive black holes slow star growth in nearby galaxies

Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years ...
