New research on an enzyme linked to cancer development shows that 37 percent of mice that produce excessive quantities of the enzyme developed skin tumors within four to 12 months of birth, and many of these growths progressed to highly invasive squamous cell carcinoma, a common form of skin cancer.
Hope for healthier airways may be on the horizon thanks to a human airway muscle-on-a-chip that could be used to test new drugs because it accurately mimics the way smooth muscle contracts in the human airway, under normal circumstances and when exposed to asthma triggers.
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.
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.
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.
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.
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.
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.
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.
