Research shows that nerves may play a critical role in stomach cancer growth and that blocking nerve signals using surgery or Botox (onabotulinumtoxinA) could be an effective treatment for the disease.
Scientists have discovered an area of the brain that could control a person’s motivation to exercise and participate in other rewarding activities, potentially leading to improved treatments for depression.
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.
A newborn screening test for severe combined immunodeficiency (SCID) reliably identifies infants with this life-threatening inherited condition, leading to prompt treatment and high survival rates, according to a new study.
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.
A researcher believes that the potential human health implications of bee colony collapse disorder extend beyond the drop in pollination to the impact on humans of long exposure to low-level poisons, like neonicotinoid pesticides.
As anyone who has bitten into a chili pepper knows, its burning spiciness— though irresistible to some — is intolerable to others. Scientists exploring the chili pepper’s effect are using their findings to develop a new drug candidate for many kinds of pain.
Printing whole new organs for transplants sounds like something out of a sci-fi movie, but the real-life budding technology could one day make actual kidneys, livers, hearts and other organs for patients who desperately need them.
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.
Chemical engineers have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, the scaffold induces the body to rapidly form new bone that looks and behaves just like the original tissue.
A single factor can reset the immune system of mice to a state likely similar to what it was 500 million years ago. Scientists reactivated expression of an ancient gene in mice, which is not normally expressed in the mammalian immune system, and found that the animals developed a fish-like thymus.
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.
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?
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.
