Life expectancy, affected by numerous factors such as better nutrition and availability of vaccines, has increased. Around 150 years ago it was something like 40 years old, and 1,000 years ago about 25. But even as we increasingly reach what appear to be the limits of lifespan, there is likely still scope for even longer lifespans.
The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But scientists now report a way to potentially inject stem cells from tonsils to repair damaged livers without surgery.
Doctors at three leading research institutions and the American Diabetes Association report that treating patients with prediabetes as if they had diabetes could help prevent or delay the most severe complications associated with this chronic disease.
How people perceive and taste alcohol depends on genetic factors, and that likely influences whether they "like" and consume alcoholic beverages, according to researchers.
Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains, according to new research.
A Red Cross team was attacked while collecting bodies believed to be infected with Ebola in southeastern Guinea, the latest in a string of assaults that are hindering efforts to control West Africa's current outbreak.
A $3.7 million grant will allow Purdue University researchers to study how blueberries reduce bone loss in postmenopausal women. The project begins Sept. 30 under a five-year grant from the National Institutes of Health's National Center for Complementary and Alternative Medicine.
A new study focused on mental well-being found that high and low mental well-being were consistently associated with an individual’s fruit and vegetable consumption.
Researchers have found that when the protein matrix metalloproteinase-14 (MMP-14) is reduced or lost, white blood cells, known as macrophages, become good and could prevent hardening of the arteries, rupture and sudden death.
Carbon nanotubes serve as bridges that allow electrical signals to pass unhindered through new pediatric heart-defect patches invented at Rice University and Texas Children’s Hospital.
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.
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 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.
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.
