Here’s another reason why it’s a good idea to hit the gym: it can improve memory. A new study shows that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent in healthy young adults.
The Rhode Island Health Department says a child has died from complications of an unusual respiratory virus that has been affecting children across the U.S.
U.S. health officials have warned for months that someone infected with Ebola could unknowingly carry the virus to this country, and there is word now that it has happened: A traveler in a Dallas hospital became the first patient diagnosed in the U.S.
The use of broad-spectrum antibiotics by children before the age of 24 months was associated with increased risk of obesity in early childhood, according to a new study.
Striving to shine a light on potential ethical conflicts in medicine, the Obama administration is releasing data on drug company payments to tens of thousands of individual doctors.
Researchers have developed a scaling law that predicts a human’s risk of brain injury, based on previous studies of blasts’ effects on animal brains. The method may help the military develop more protective helmets, as well as aid clinicians in diagnosing traumatic brain injury.
Researchers have shown for the first time that a genetic switch allows Streptococcus pneumoniae to randomly change its characteristics into six alternative states.
Researchers from the National Cancer Institute want to know how many past and present cancer cases in New Mexico may be related to the U.S. government's test of the world's first atomic bomb over a remote stretch of desert nearly 70 years ago.
U.S. mobile Ebola labs should be up and running in Liberia this week, and American troops have broken ground for a field hospital, as the international community races to increase the ability to care for the spiraling number of people infected with the dreaded disease.
Ten times more stem cells may soon be generated from umbilical cords than ever before, according to a new Science study. The potential advance was made via a little-known pyrimidoindole molecule called UM171.
How the brain ages is still largely an open question– in part because this organ is mostly insulated from direct contact with other systems in the body, including the blood and immune systems. Now, new research may have found evidence of a unique “signature” that may be the “missing link” between cognitive decline and aging.
Researchers have shown that low levels of the protein progranulin in the brain can increase the formation of amyloid-beta plaques (a hallmark of Alzheimer’s disease), cause neuroinflammation, and worsen memory deficits in a mouse model of this condition.
Years before they show any other signs of disease, pancreatic cancer patients have very high levels of certain amino acids in their bloodstream, according to a new study.
An excruciating mosquito-borne illness that arrived less than a year ago in the Americas is raging across the region, leaping from the Caribbean to the Central and South American mainland, and infecting more than 1 million people.
Health officials are investigating nine cases of muscle weakness or paralysis in Colorado children and whether the culprit might be a virus causing severe respiratory illness across the country.
An American doctor who was exposed to the Ebola virus while volunteering in Sierra Leone has been admitted for observation at The National Institutes of Health near the nation's capital. NIH confirmed in a news release on its website that the physician arrived Sunday.
Tests on the brains of macaques have shown that neurons in at least two regions of the brain, the temporal and frontal lobes, are responsible for deciding which impressions reach our consciousness.
High levels of calcium in blood, a condition known as hypercalcemia, can be used by GPs as an early indication of certain types of cancer, according to a new study.
A new study further supports an inescapable message: caregivers have a profound influence— good or bad— on the emotional state of individuals with Alzheimer’s disease.
New research has answered the long-standing question of why mutations to the RB1 gene primarily cause tumors of the retina and not of other cell types. The study could reveal new cellular signaling pathways relevant to retinal development, cancer development, and ultimately, the development of novel therapies.
Bacillus anthracis bacteria have very efficient machinery for injecting toxic proteins into cells, leading to the potentially deadly infection known as anthrax. A team of researchers has now hijacked that delivery system for a different purpose: administering cancer drugs.
The first animal model for ALS dementia, a form of ALS that also damages the brain, has been developed by scientists. The advance will allow researchers to directly see the brains of living mice, under anesthesia, at the microscopic level.
An analysis of circulating tumor cells (CTCs) in a mouse model of pancreatic cancer has identified distinct patterns of gene expression in several groups of these cells, including significant differences from the primary tumor that may contribute to their ability to spread.
Scientists have provided experimental evidence supporting dromedary camels as the primary reservoir, or carrier, of Middle East respiratory syndrome coronavirus (MERS-CoV).
Scientists have developed an approach to creating treatments for osteoporosis and autoimmune diseases that may avoid the risk of infection and cancer posed by some current medications.
