Probiotics may be a way to alleviate the symptoms of seasonal or perennial allergies. “When you look at all the studies combined, there was a statistically significant improvement in both the rhinitis-specific quality of life of those patients and in their nasal specific quality of life,” says lead author Justin Turner, assistant professor of otolaryngology at Vanderbilt University.
New evidence pushes back the origin of the turtle’s shell by about 40 million years, linking it to a 260-million-year-old fossil reptile from South Africa.
A healthy diet may offer some protection from hearing loss due to noise exposure, however it can’t reverse hearing damage, a new study shows.
A new study finds that use of illegal drugs other than marijuana was about 20 percent higher among teenagers who attend raves, compared to those who don’t.
Smokers are four times more likely than non-smokers to frequently visit emergency rooms. A new study, which explores how much patients replace visits to a primary care physician with a trip to a hospital emergency room, also shows Americans with chronic diseases use both services equally.
The herpes virus led researchers to discover the respiratory tract links two different parts of the nervous system.
A man who is paralyzed from the neck down can now move a robotic arm just by thinking about it. Neural prosthetic devices implanted in the brain’s movement center, the motor cortex, have allowed patients with amputations or paralysis to control the movement of a robotic limb—one is either connected to or separate from the patient’s own limb.
The question of whether nature or nurture governs our health is one of science’s great debates. Scientists reviewed almost every twin study across the world from the past 50 years, involving more than 14.5 million twin pairs.
In a wooden building overlooking the Pacific Ocean, 3,800 gallons of seawater empty into a long, clear, covered tank—a wave machine.
Black bears in Alaska are more closely related to bears in the eastern regions of the United States and Canada than those located in western regions, according to a new “genetic map” that reveals the animals’ ancient movement patterns.
With up to 40 percent of children experiencing a range of sleep problems, parents are turning to specialized devices and smartphone apps—even though it’s unknown if the information will accurately reflect their children’s rest.
Paleontologists have documented a new dinosaur fossil—part of a three-foot-long femur with fossilized prehistoric clams inside it.
The success of corals that adapt to survive in the world’s hottest sea could actually contribute to their demise.
Arctic temperatures are increasing two to three times faster than those at the mid-latitudes, and researchers say there’s fresh evidence suggesting a link between that warm-up and extreme weather in other parts of the world.
The discovery of the earliest stone artifacts ever found—dating to some 3.3 million years ago—suggests our ancestors were making stone tools about 700,000 years earlier than we originally thought.
Some people who could benefit from a common screening test for osteoporosis aren’t getting them, according to new research.
Foster children are four times more likely to move and change elementary schools during an academic year than children not in foster care.
The octopus can change the color, pattern, and even texture of its skin not only for purposes of camouflage but also as a means of communication.
Women who decline to participate in a clinical trial may be significantly more likely to later regret that decision than women who choose to participate, say researchers.
Wild primates are known for helping their pals stay clean and free of lice. But by picking ecto-parasites out of friends’ fur, they may be picking up internal ones themselves.
