Depressed people who turn to their smartphones for relief may only be making things worse. A team of researchers found that people who substitute electronic interaction for the real-life human kind find little, if any, satisfaction.
Studies have shown that physically fit people tend to have larger brain volumes and more intact white matter than their less-fit peers. Now, a new study reveals that older adults who regularly engage in moderate to vigorous physical activity have more variable brain activity at rest than those who don’t.
A bicoastal team of marine biologists has developed and tested a new noninvasive method of diagnosing the health of endangered whales that relies on a small, unmanned drone. The drone, called a hexacopter because it has six whirling rotors, collects data from two different altitudes.
New research by a psychological scientist and his collaborators across the globe has found a simple exercise that can undo the unconscious racial biases that young children have— biases that may begin to develop as early as infancy.
A prestigious laboratory is under federal investigation after auditors issued a preliminary report saying it didn't do enough to prevent the suffering of primates who were infected with a deadly virus for a study of the disease. The NIAID found a variety of procedural errors with a study conducted at the Galveston National Laboratory, one of the nation's leading research facilities seeking vaccines for some of the most lethal diseases.
The Earth was once like a snowball, completely frozen over, like a vision of an alien world from a science-fiction movie, some scientists say. New research of a grouping of sedimentary rocks in Norway shows that the melting of the ice was gradual– and irregular– owing to the planet’s wobbling on its axis.
A Cessna 172 will plummet 100 feet out of the sky, tail-first, to the ground in Virginia on Wednesday afternoon. Aboard will be five emergency locator transmitters, data-collecting sensors– and two crash-test dummies, NASA said.
Researchers are developing an "augmented reality telementoring" system to provide effective support to surgeons on the battlefield from specialists located thousands of miles away. The new System for Telementoring with Augmented Reality (STAR) harnesses various technologies such as transparent displays and sensors to improve the quality of the communication between mentor and surgeon.
Black bears in Yosemite National Park that don’t seek out human foods subsist primarily on plants and nuts, according to a study conducted by biologists who also found that ants and other sources of animal protein, such as mule deer, make up only a small fraction of the bears’ annual diet.
It’s hard to overestimate the importance of high-quality sleep. Men and persons age 65 and older who have access to natural surroundings, whether it’s the green space of a nearby park or a sandy beach and an ocean view, report sleeping better.
Resveratrol, a compound found commonly in grape skins and red wine, has been shown to have several potentially beneficial effects on health, including cardiovascular health, stroke prevention and cancer treatments. However, scientists do not yet fully understand how the chemical works and whether or not it can be used for treatment of diseases in humans and animals.
With increasing concern about concussions from sports, some players have started wearing electronic sensors to measure head impacts. But a new study has found that some of the sensors for non-helmeted sports are not fast enough to measure hard hits and don’t accurately measure what are thought to be the most serious, angular hits.
Engineers and physicians have developed a hand-held, battery-powered device that quickly picks up vital signs from a patient’s lips and fingertip. Updated versions of the prototype, called MouthLab, could replace the bulky, restrictive monitors now used to display patients’ vital signs in hospitals and gather more data.
Fish have the fascinating ability to fully regenerate amputated organs. When parts of a zebrafish’s tailfin are injured by predators, or are experimentally amputated, the lost tissue is replaced within three weeks. Now, researchers have learned how zebrafish manage to regenerate the exact shape of the lost fin skeleton.
Yes, a good cry indeed might go a long way to make you feel better, says a study. The find was established when a research team videotaped a group of participants while watching emotionally charged films. Afterwards, the participants were asked a few times to reflect on how they felt.
