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.
Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study.
Scientists have discovered an on-and-off “switch” in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age.
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.
The Food and Drug Administration on Friday revised sweeping food safety rules proposed last year after farmers complained that the regulations could hurt business.
Neural stem cells– master cells that can develop into any type of nerve cell– are able to generate mini “first aid kits” and transfer them to immune cells, according to a new study.
Signaling the seriousness of the threat posed by antibiotic-resistant germs, President Barack Obama on Thursday ordered the government to create a national plan to fight them by early 2015.
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.
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.
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.
