The Ebola virus that has killed scores of people in Guinea this year is a new strain - evidence that the disease did not spread there from outbreaks in some other African nations, scientists report.
Teenagers who have suffered a traumatic brain injury such as a concussion are at “significantly greater odds” of attempting suicide, being bullied and engaging in a variety of high risk behaviors, a new study has found.
Cases of diabetes and pre-diabetes in the United States have nearly doubled since 1988, suggests new research, with obesity apparently to blame for the surge.
Psychologists have presented the first study to reveal that our brains rely on an active suppression mechanism to avoid being distracted by salient irrelevant information when we want to focus on a particular item or task.
It’s long been known that certain strains of human papillomavirus (HPV) cause cancer. Now, researchers have determined a new way that HPV might spark cancer development– by disrupting the human DNA sequence with repeating loops when the virus is inserted into host-cell DNA as it replicates.
Young adults who used marijuana only recreationally showed significant abnormalities in two brain regions that are important in emotion and motivation. This is the first study to show casual use of marijuana is related to major brain changes.
Depression can hit young fathers hard- with symptoms increasing dramatically during some of the most important years of their children’s lives, a new study has found.
The first human volunteer will receive red blood cells cultured in the laboratory within the next three years, as part of a long-term research program funded by the Wellcome Trust.
If you follow cancer biology, then you’ve probably heard of ubiquitin before. In a recent paper researchers provided a structural rationale for how ubiquitin helps RIG-I do its job— and how that might help keep the immune system from getting out of hand.
A mumps outbreak in central Ohio has grown to more than 200 confirmed cases, public health officials said. A total of 212 cases of the contagious viral illness, with 132 of those linked to Ohio State University, have been reported.
The more cups of coffee a person drank, the lower the risk for developing hepatocellular carcinoma (HCC), the most common type of liver cancer, according to new research.
Researchers have devised a way to quickly bring to the clinic the technique of using blood samples to diagnose many types of solid cancers, or to monitor the amount of cancer in a patient’s body and responses to treatment.
Researchers have succeeded in developing a method fast enough to observe immediate changes in the function of the brain even when watching a movie. When we watch a movie, our brains react to it immediately in a way similar to other people's brains.
In a new study, researchers solved an age-old mystery of touch: how cells just beneath the skin surface enable us to feel fine details and textures.
Scientists may have discovered a new way to treat a type of childhood brain tumor that has proved incurable up until now, according to a recent study.
Researchers have generated a 3-D model of the human malaria parasite genome at three different stages in the parasite’s life cycle— the first time such 3-D architecture has been generated during the progression of the life cycle of a parasite.
A research team was able to demonstrate for the first time that caffeine has a positive effect on tau deposits in Alzheimer's disease. Tau deposits, along with beta-amyloid plaques, are among the characteristic features of Alzheimer's disease.
In their pursuit of understanding how pain works at the molecular level, a research team has found a new function for MicroRNAs, short stretches of genetic material that signal genes to turn on or off.
Chances are you've heard of mapping genes to diagnose rare diseases, predict your risk of cancer and tell your ancestry. But to uncover food poisonings? The nation's disease detectives are beginning a program to try to outsmart outbreaks by routinely decoding the DNA of potentially deadly bacteria and viruses.
Neuroscientists report they have identified what they believe is the cause of the vast disintegration of a part of the brain called the corpus striatum in rodents and people with Huntington’s disease: loss of the ability to make the amino acid cysteine.
In a series of studies researchers have used specialized 3-D MRI scans to precisely measure living and dying tumor tissue to quickly show whether highly toxic chemotherapy is working.
A team of researchers believe their findings could have important implications for the way that rheumatoid arthritis is diagnosed and treated. They say that more accurate clinical testing is now needed to better identify rheumatoid arthritis and to prevent it being misdiagnosed.
The formula for peak exercise heart rate that doctors have used for decades in tests to diagnose heart conditions may be flawed because it does not account for differences between men and women, new research says.
Cholesterol levels fluctuate based on the time of year with more unfavorable lipid profiles seen in the colder months, a trend that may be driven by related behavior changes, according to new research.
A small study that examined brains from children who died found abnormal patterns of cell growth in autistic children. The research bolsters evidence that something before birth might cause autism, at least in some cases.
