After nearly three weeks of treatment, the two American aid workers who were infected with the deadly Ebola virus in Africa have been discharged from an Atlanta hospital, officials have said.
Coffee contains antioxidants. Antioxidants fight gum disease. Researchers in dental medicine have found that coffee consumption does not have an adverse effect on periodontal health, and may have protective effects against periodontal disease.
The National Park Service has banned drones from flying over the Appalachian Trail. The Park Service said the interim rule prohibits launching, landing or operating unmanned aircraft from or on Appalachian National Scenic Trail lands.
Nearly one-fifth of 16-year-olds surveyed reported getting less than six hours of sleep. This group was 20 percent more likely to be obese by age 21, compared to their peers who got more than eight hours of sleep.
New research has found that, contrary to the “good genes hypothesis,” facial symmetry is not a marker of health and resilience. Nor does it indicate how well people cope with environmental or genetic challenges.
Researchers have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals moths use to control those muscles. The work opens the door to the development of remotely controlled moths, or “biobots,” for use in emergency response.
A team of researcher used a standard TENS machine to apply electrical pulses to the tragus, the small raised flap at the front of the ear immediately in front of the ear canal. The stimulation changed the influence of the nervous system on the heart by reducing the nervous signals that can drive failing hearts too hard.
Alan Feduccia and Stephen Czerkas found that a birdlike fossil, called a Scansoriopteryx, is not a dinosaur, as previously thought, but much rather the remains of a tiny tree-climbing animal that could glide. Their find challenges the commonly held belief that birds evolved from ground-dwelling theropod dinosaurs that gained the ability to fly.
Authorities have evacuated tourists from an area north of Iceland's largest glacier amid increased seismic activity around a volcano in the past few days.
Humans and Neanderthals may have coexisted in Europe for more than 5,000 years, providing ample time for the two species to meet and mix, according to new research.
A new study of over 10,000 mothers has shown that women who breastfed their babies were at significantly lower risk of postnatal depression than those who did not.
Have you ever wondered why we give birth to live young rather than lay eggs? Scientists have pondered this for a long time and answers have come from an unlikely source: some of Australia’s lizards and snakes.
Endothelial cells residing in the coronary arteries can function as cardiac stem cells to produce new heart muscle tissue, investigators have discovered. The findings offer insights into how the heart maintains itself and could lead to new strategies for repairing the heart when it fails after a heart attack.
Your chairs, synthetic rugs and plastic bags could one day be made out of cocoa, rice and vegetable waste rather than petroleum, scientists are now reporting. The novel process they have developed could help the world deal with its agricultural and plastic waste problems.
A new study suggests that colds and other minor infections may temporarily increase stroke risk in children. But, while the study does show an increased risk, the overall risk of stroke among kids is extremely low.
