Researchers say a new focus on the links between the immune system and stress is needed to help pave the way for improved treatments of severe depression. The paper argues that current treatments for major depressive disorder lack effectiveness.
Spontaneous mutations in the brain gene TBR1 disrupt the function of the encoded protein in children with severe autism. In addition, there is a direct link between TBR1 and FOXP2, a well-known language-related protein, according to a new study.
A treatment regimen is safe and effective for restoring skin pigmentation in vitiligo patients, according to a new study. Patients were randomly divided into two study groups: Group A received a combination therapy; Group B received only NB UVB treatment.
Stanford scientists have shown how the brain changes throughout life, and created a standard curve that can be used to assess whether patients are maturing and aging normally.
By comparing nine ancient genomes to those of modern humans, scientists have shown that previously unrecognized groups contributed to the genetic mix now present in most modern-day Europeans.
Shoppers in Sierra Leone rushed to stock up on food Thursday ahead of a three-day nationwide shutdown, during which the country's 6 million people will be confined to their homes while volunteers search house-to-house for Ebola victims in hiding and hand out soap in a desperate bid to slow the accelerating outbreak.
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity.
On this episode of Bioscience Technology This Week, Christina Jakubowski reports on new research seeking to prove how life on Earth began, by tracking the ancestors of RNA and DNA. Our second story focuses on the possibility of developing high-quality computed tomography scans from a lower radiation dose.
Using artificial sweeteners may set the stage for diabetes in some people by hampering the way their bodies handle sugar, suggests a preliminary study done mostly in mice.
Aging of insulin-secreting cells is coupled to a progressive decline in signal transduction and insulin release, according to a recent study. The finding provides a new molecular mechanism underlying age-related impairment of insulin-producing cells and diabetes.
The same viruses that make us sick can take up residence in and on the human body without provoking a sneeze, cough or other troublesome symptom, according to new research.
A simple point-of-care testing device for anemia could provide more rapid diagnosis of the common blood disorder and allow inexpensive at-home self-monitoring of persons with chronic forms of the disease.
The number of American men and women with big-bellied, apple-shaped figures — the most dangerous kind of obesity — has climbed at a startling rate over the past decade, according to a government study.
A peek inside the brains of more than 750 children and teens reveals a key difference in brain architecture between those with attention deficit hyperactivity disorder and those without.
Since the Ebola outbreak first emerged in West Africa, The Associated Press has been reporting on it. A timeline compiled from AP dispatches since March shows the dreaded disease being identified in a remote part of Guinea and then spreading to another country and then two more.
A new study shows how schizophrenia is associated with increased rates and intensity of tobacco smoking by showing that the level of nicotine receptors in the brain was lower in schizophrenia patients than in a matched healthy group.
Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans’ unique ability to produce and understand speech.
Researchers have identified nine genetic variants that dramatically increase the risk of developing type 2 diabetes, adding to our knowledge of the disease’s underpinnings and providing a glimpse of its vast genetic diversity.
The number of Ebola cases in West Africa could start doubling every three weeks and it could end up costing nearly $1 billion to contain the crisis, the World Health Organization warned Tuesday.
A rare genetic disorder known as Jacobsen syndrome has been linked with autism, according to a recent joint investigation by researchers. In addition to suggesting better treatment options for people with Jacobsen syndrome, the finding also offers more clues into the genetic underpinnings of autism.
Things can go downhill fast when a patient has sepsis, a life-threatening condition in which bacteria or fungi multiply in the blood—often too fast for antibiotics to help. A new device inspired by the human spleen may radically transform the way doctors treat sepsis.
The human brain is capable of a neural workaround that compensates for the buildup of beta-amyloid, a destructive protein associated with Alzheimer’s disease, according to a new study.
The American strategy on Ebola is two-pronged: Step up desperately needed aid to West Africa and, in an unusual step, train U.S. doctors and nurses for volunteer duty in the outbreak zone.
An anti-addiction drug used to fight the nation's heroin and painkiller abuse epidemics poses a threat to young children who accidentally swallow relatives' prescriptions, a federal study says. Some children have died.
On this episode of Bioscience Technology This Week, Christina Jakubowski explores the role that bees may play in the search for antibiotic alternatives. Our second story focuses on how increased carbon dioxide levels in water can rob sharks of their ability to sense the smell of food.
