Who needs science fiction when you have the mitochondria? Billions of years ago, early plant and animal cells were infected by protobacteria which sought refuge from the outside world. Over time, these bacteria formed a symbiosis ...
Nearly 1,000 birds were killed Oct. 4–5 when they collided with an illuminated glass building in Chicago. Though mass fatalities of this magnitude are rare, light pollution poses a serious—and growing—threat to migrating ...
RUDN University agronomists and colleagues from China and Iran have helped tomatoes cope with the toxic effect of aluminum in acidic soils with the help of melatonin. This hormone contributes to nitric oxide production, blocking ...
The internal clocks of grizzly bears appear to keep ticking through hibernation, according to a genetic study. This persistence highlights the strong role of circadian rhythms in the metabolism of many organisms including ...
Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers "see" the sun to follow it? New work from plant biologists at the University of California, Davis, published Oct. 31 in PLOS ...

Researchers from Tokyo Metropolitan University have used fruit flies to study how daily eating patterns are regulated. They found that the quasimodo (qsm) gene helped sync feeding to light/dark cycles, but not in constant ...
University of Maryland researchers studied synaptic changes in an animal model before and after it developed vision, which plays a key role in circadian rhythm.
Aleksandra Stankovic is an aerospace psychologist and spaceflight biomedical researcher who studies how to optimize human performance and behavioral health in extreme operational environments. In this article, she describes ...
A team led by Tappei Mishina at the RIKEN Center for Biosystems Dynamics Research (BDR) has discovered that parasites manipulate their hosts using stolen genes that they likely acquired through a phenomenon called horizontal ...
