For the first time, a research team has succeeded in restoring a missing repair protein in skeletal muscle of patients with muscular dystrophy.
As people grow older, they often have difficulty falling asleep and staying asleep, and tend to awaken too early in the morning. Now, a new study helps explain why sleep becomes more fragmented with age.
Scientists who study tuberculosis have long debated its origins. New research shows that tuberculosis likely spread from humans in Africa to seals and sea lions that brought the disease to South America and transmitted it to Native people there before Europeans landed on the continent.
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 said Thursday.
The enzyme phospholipase D (PLD) helps the influenza virus escape the immune response, and blocking it could lead to a new way to prevent the flu.
New work by scientists suggests that both major forms of diabetes, type 1 and type 2, are the result of the same mechanism - the formation of toxic clumps of a hormone called amylin.
Scientists have made it easier to predict both breast cancer relapses and responses to chemotherapy, through the identification of a unique gene, a new study shows.
Male stickleback fish that protect their young have bigger brains than counterparts - male white sticklebacks, which do not tend to their offspring - a new study found.
A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit.
When investigators applied light-driven stimulation to nerve cells in the brains of mice that had suffered strokes several days earlier, the mice showed significantly greater recovery in motor ability than mice that had experienced strokes but whose brains weren’t stimulated.
Medical researchers have used DNA sequencing to identify a gene variant responsible for causing lupus in a young patient. The development shows that, for the first time, it is feasible for researchers to identify the individual causes of lupus in patients by using DNA sequencing.
Scientists have made a breakthrough in the fight against the most resistant hospital superbugs by developing the first innovative antibacterial gel that acts to kill Pseudomonas aeruginosa, staphylococci and E. coli, using natural proteins.
Mice missing two important proteins of the vascular system develop normally and appear healthy in adulthood, as long as they don’t become injured. If they do, their wounds don’t heal properly, a new study shows.
The U.N. health agency says the Ebola outbreak in West Africa has now killed more than 1,200 people. The World Health Organization says the death toll has risen to 1,229 from among the 2,240 reported cases in Guinea, Liberia, Nigeria and Sierra Leone.
NGS is revolutionizing the field of genome biology, with much faster data generation, increased accuracy, and a dramatic reduction of sequencing costs. Multiple genomes can now be sequenced in parallel by a single instrument in a matter of days. In the medical field, NGS is already having an impact in genetic screening and holds great potential in oncology, given the genetic aspects of cancerous disease.
It sounds like science fiction, but it seems that bacteria within us– which outnumber our own cells about 100-fold– may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity.
An estimated 55 million to 105 million people in the United States suffer from foodborne illnesses each year, according to the CDC, resulting in costs of $2 to $4 billion annually. What if Twitter could be used to track those cases and more quickly identify the source of the problem?
A team of researchers has uncovered some of the strongest evidence yet that epigenetic changes in the brain play a role in Alzheimer’s disease. The current study found that chemical modifications to DNA within the ANK1 gene are strongly associated with measures of neuropathology in the brain.
New research found that receiving antibiotic treatments early in life can increase susceptibility to specific diseases later on. The study helps scientists understand how different antibiotics affect good bacteria.
A genetic variation linked to schizophrenia, bipolar disorder and severe depression wreaks havoc on connections among neurons in the developing brain, a team of researchers reports.
A scary problem lurks beyond the frenzied efforts to keep people from spreading Ebola: No one knows exactly where the virus comes from or how to stop it from seeding new outbreaks.
On this episode of Bioscience Technology This Week, Christina Jakubowski reports on the possibility of making nuts safer to eat for those with allergies. Our second story tackles important questions about which genes may drive antibiotic resistance.
Ever wonder why it’s hard to focus after a bad night’s sleep? Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions.
An investigation into a potentially dangerous blunder at a government lab found that a scientist kept silent about the accident and revealed it only after other employees noticed something fishy.
Links between a number of common respiratory diseases and an increased risk of developing lung cancer have been found in a large pooled analysis of seven studies involving more than 25,000 individuals.
