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...
Researchers from the National Cancer Institute want to know how many past and present cancer...
U.S. mobile Ebola labs should be up and running in Liberia this week, and American troops...
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.
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.
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.
The Obama administration is tightening oversight of high-stakes scientific research involving dangerous germs that could raise biosecurity concerns, imposing new safety rules on universities and other institutions where such work is done.
New research suggests that people who notice their memory is slipping may be on to something. The research appears to confirm that self-reported memory complaints are strong predictors of clinical memory impairment later in life.
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.
On this episode of Bioscience Technology This Week, Christina Jakubowski covers research showing that measuring the brain’s response to sights and sounds can help in classifying people on the autism spectrum. Our second story looks at how the human response to unfairness may have involved in support of long-term cooperation.
An enzyme found in all living things could be key to fighting deadly parasite-borne diseases, according to a new study. Research into the enzyme, which helps cells convert nutrients into energy, has shown that it is activated in different ways in various species.
Life expectancy, affected by numerous factors such as better nutrition and availability of vaccines, has increased. Around 150 years ago it was something like 40 years old, and 1,000 years ago about 25. But even as we increasingly reach what appear to be the limits of lifespan, there is likely still scope for even longer lifespans.
The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But scientists now report a way to potentially inject stem cells from tonsils to repair damaged livers without surgery.
Doctors at three leading research institutions and the American Diabetes Association report that treating patients with prediabetes as if they had diabetes could help prevent or delay the most severe complications associated with this chronic disease.
How people perceive and taste alcohol depends on genetic factors, and that likely influences whether they "like" and consume alcoholic beverages, according to researchers.
Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains, according to new research.
