Individual differences in early language development, and in later language functioning, are associated with changes in the anatomy of the brain in autism. A new study has found that a common characteristic of autism– language delay in early childhood– leaves a "signature" in the brain.
New estimates by the World Health Organization and the U.S. health agency are warning that the number of Ebola cases could soar dramatically — the U.S. says up to 1.4 million by mid-January in two nations alone — unless efforts to curb the outbreak are significantly ramped up.
A new study reports preliminary results showing that a blood test, when used in psychiatric patients experiencing symptoms that are considered to be indicators of a high risk for psychosis, identifies those who later went on to develop psychosis.
Researchers found that participants with a western dietary pattern scored lower in cognitive tasks, particularly those involving reaction time/psychomotor function, visual attention, learning and memory.
A news conference to announce the results of a three-day nationwide shutdown designed to help stop the spread of Ebola has been postponed to give officials who fanned out across the country time to reach the capital.
More than 700 infants may have been exposed to tuberculosis at an El Paso hospital over the past year by an employee recently diagnosed with the illness, health officials said Friday.
On this episode of Bioscience Technology This Week, Christina Jakubowski focuses on a new study that used a short movie to detect consciousness in vegetative state patients. Our second story explores how the amazing variety in human faces is the result of evolutionary pressure.
While previous studies of the brain suggest that processing of objects and place occur in very different locations, a research team has found that they are closely related.
A group of international scientists have developed a new method to study Ebola virus in wildlife. The research describes the use of fecal samples from wild great apes to identify populations likely to have been exposed to the virus.
For years, neuroscientists have been trying to develop tools that would allow them to clearly view the brain's circuitry in action— from the first moment a neuron fires to the resulting behavior in a whole organism.
A new study has shown that people who eat more protein- whether from plant or animal sources- tend to have a lower risk of hypertension, also known as high blood pressure.
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.
Scientists have found that confidence is actually a measureable quantity, and not reserved just for humans. The team has identified a brain region in rats whose function is required for the animals to express confidence in their decisions.
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.
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.
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.
Mutations in the human retinoblastoma protein gene are a leading cause of eye cancer. Now, scientists have turned to fruit fly eyes to unlock the secrets of this important cancer gene.
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.
Researchers have identified clues to explain how breast implants may, on very rare occasions, contribute to the development of lymphoma. There have been 71 known cases worldwide of a type of blood cancer called anaplastic large cell lymphoma (ALCL) that the researchers suggest were associated with the patient's breast implants.
Researchers have used brain scans to predict how young children learn to read, giving clinicians a possible tool to spot children with dyslexia and other reading difficulties before they experience reading challenges.
