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.
One of the most rapidly fast-tracked vaccines in history— an anti-Ebola “ChAd3” vaccine— just started clinical trial in humans, and may be done as soon as November. But a second fast-tracked anti-Ebola vaccine— called an “rVSV” vaccine— is hot on its heels.
Mice treated with antibiotics to remove most of their intestinal bacteria or raised under sterile conditions have impaired antibody responses to seasonal influenza vaccination, researchers have found.
Using human induced pluripotent stem cells (hiPSCs), researchers have discovered that neurons from patients with schizophrenia secrete higher amounts of three neurotransmitters broadly implicated in a range of psychiatric disorders.
A research team is looking at whether an antibiotic has the potential to prevent or treat irregular heartbeats brought on by other medicines, thanks to a grant from national charity in the UK.
Employing a measure rarely used in sleep apnea studies, researchers uncovered evidence of what may be damaging the brain in people with the sleep disorder— weaker brain blood flow.
The race to stamp out West Africa’s Ebola epidemic is not just about saving lives. It’s also about stemming an assault on society that could include food shortages and mass migration, morphing from a medical emergency into a broad humanitarian crisis.
A pharmacist who worked for a Massachusetts company blamed for a 2012 deadly nationwide meningitis outbreak has pleaded not guilty. Glenn Adam Chin entered his plea to a mail fraud charge at a brief hearing Thursday in federal court in Boston.
Researchers are working to create an online platform that health workers around the world can use to predict where malaria is likely to be transmitted using data on Google Earth Engine. Read more...
