New experiments have identified a compound that might halt the progression of Alzheimer’s by interfering with the role amyloid-beta plays in the formation of blood clots.
Scientists have discovered that obese individuals lack a protein that is essential for regulating blood glucose levels, causing them to face higher risks of developing diabetes.
By looking at the copy of the human genome present in healthy cells, researchers were able to build a picture of each cell's development from the early embryo on its journey to become part of an adult organ.
Optogenetics requires a light source to be implanted in the brain, where it can reach the cells that need to be controlled. Now, engineers have developed the first light-sensitive molecule that enables neurons to be silenced noninvasively, using a light source outside the skull.
By switching off a single gene, scientists have converted human gastrointestinal cells into insulin-producing cells, demonstrating in principle that a drug could retrain cells inside a person's GI tract to produce insulin.
An international research team has solved the mystery of how birds avoid Lassa virus infection, leading to a better understanding of how Lassa virus infects mammals.
Environmental policy must respond to ever-changing conditions on the ground and in the water, but doing so requires a constant flow of information about the living world. Now, scientists propose employing emerging environmental DNA sampling techniques that could make assessing the biodiversity of marine ecosystems as easy as taking a water sample.
Chronic hepatitis C virus infections are among the most common reasons for liver transplants. Because existing viruses also infect the new liver, the immune system is highly active there. Despite this, the new organ is not rejected. The long-term stimulation of the innate immune system by the virus actually increases the probability of tolerance.
The longer a person took low-dose aspirin, the lower their risk for developing pancreatic cancer, according to a recently published study. Men and women who took low-dose aspirin regularly had 48 percent reduction in their risk for developing pancreatic cancer. Protection ranged from 39 percent reduction in risk for those who took low-dose aspirin for six years or less, to 60 percent reduction for those who took it for more than 10 years.
Adults who watch TV for three hours or more each day may double their risk of premature death compared to those who watch less, according to new research.
Bone marrow transplants save thousands of lives but patients are vulnerable to severe viral infections in the months afterward. Now, scientists are developing protection for that risky period — injections of cells specially designed to fend off up to five different viruses at once.
As many patients know, treating wounds has become far more sophisticated than sewing stitches and applying gauze, but dressings still have shortcomings. Now scientists are reporting the next step in the evolution of wound treatment with a material that leads to faster healing than existing commercial dressings and prevents potentially harmful bacteria from sticking.
Scientists have found that eating almonds in your diet can reduce the risk of heart disease by keeping blood vessels healthy and significantly increasing the amount of antioxidants in the blood stream.
A gene known to control brain growth and development is heavily involved in promoting clear cell renal cell carcinoma, the most common form of kidney cancer, researchers are reporting.
3-D mammograms may be better at finding cancer than regular scans, a large study suggests, although whether that means saving more lives isn't known. The study involved almost half a million breast scans, with more than one-third of them using relatively new 3-D imaging along with conventional scans.
Researchers have shown that a favorable electrical property is present in a type of protein found in organs that repeatedly stretch and retract, such as the lungs, heart and arteries. These findings are the first that clearly track this phenomenon, called ferroelectricity, occurring at the molecular level in biological tissues.
Oxford University researchers have come up with a computer program that recognizes facial features in photographs; looks for similarities with facial structures for various conditions, such as Down's syndrome, Angelman syndrome, or Progeria; and returns possible matches ranked by likelihood.
A Case Western Reserve University engineer has won a $1.7 million National Institutes of Health (NIH) grant to grow replacement rotator cuffs and other large tendon groups to help heal injured soldiers and athletes, accident victims, and an aging population that wants to remain active.
Sarcopenia–the significant loss of muscle mass and function that can occur as we age–is associated with many chronic conditions such as diabetes, high cholesterol and obesity. In new findings, researchers identify a muscle-building mechanism that could be important in addressing sarcopenia.
A new survey suggests asthma in the U.S. may finally be on the decline. But the results are so surprising that health officials are cautious about claiming a downturn. The findings come from a large national health survey conducted last year. The drop could just be an unexplained statistical blip, and researchers say they are waiting for data from this year before proclaiming asthma is on the decline.
Food companies and restaurants could soon face government pressure to make their foods less salty — a long-awaited federal effort to try to prevent thousands of deaths each year from heart disease and stroke. The Food and Drug Administration is preparing to issue voluntary guidelines asking the food industry to lower sodium levels.
Investors and gamblers take note: your betting decisions and strategy are determined, in part, by your genes. Researchers have shown that betting decisions are influenced by the specific variants of dopamine-regulating genes in a person's brain.
In a new study, scientists took a molecular-level journey into microtubules, the hollow cylinders inside brain cells that act as skeletons and internal highways. They watched how a protein called tubulin acetyltransferase (TAT) labels the inside of microtubules.
Children with rare mutations in two genes are about four times more likely to develop severe scoliosis than their peers with normal versions of the genes, scientists have found.
