College-aged women judge promiscuous female peers more negatively than more chaste women and view them as unsuitable for friendship, according to psychologists.
Scientists have discovered that manipulating the levels of the protein tomosyn in a part of the brain associated with learning and memory may aid in the development of therapeutic procedures for epilepsy and neurodegenerative diseases such as Alzheimer's.
A new study shows Bertholdia trigona, a species of tiger moth found in the Arizona desert, can tell if an echo-locating bat is going to attack it well before the predator swoops in for the kill – making the intuitive, tiny-winged insect a master of self-preservation.
New Zealand's geologic hazards agency reported this week an ongoing, "silent" earthquake that began in January is still going strong. Though it is releasing the energy equivalent of a 7.0 earthquake, New Zealanders can't feel it because its energy is being released over a long period of time, therefore slow, rather than a few short seconds.
Researchers found that lookdown fish camouflage themselves through a complex manipulation of polarized light after it strikes the fish skin. In laboratory studies, they showed that this kind of camouflage outperforms by up to 80 percent the "mirror" strategy that was previously thought to be state-of-the-art in fish camouflage.
Smartphones and tablets can make for sleep-disrupting bedfellows. One cause is believed to be the bright light-emitting diodes that allow the use of mobile devices in dimly li...
Researchers have identified a new mechanism that appears to suppress tumor growth, opening the possibility of developing a new class of anti-cancer drugs.
Our Solar System's Milky Way neighborhood just went upscale. We reside between two major spiral arms of our home galaxy, in a structure called the Local Arm. New research indicates that the Local Arm, previously thought to be only a small spur, instead is much more like the adjacent major arms, and is likely a significant branch of one of them.
Most apes eat leaves and fruits from trees and shrubs. New studies show that human ancestors expanded their menu 3.5 million years ago, adding tropical grasses and sedges to an ape-like diet and setting the stage for our modern diet of grains, grasses, and meat and dairy from grazing animals.
