Blood expression levels of genes targeted by the stress hormones called glucocorticoids could be a physical measure, or biomarker, of risk for developing Post-Traumatic Stress Disorder (PTSD), according to a new study.
A gene discovery brings scientists closer to developing therapeutic agents that could slow down bone loss and regenerate lost bone, which could provide relief for millions suffering from aging-related bone loss.
Playing with the portions of good and not-so-good-for-you foods is better than trying to eliminate bad foods, according to a new study. The idea is to not give up entirely foods that provide pleasure but aren’t nutritious.
A Spanish missionary priest being treated for Ebola died Tuesday in a Madrid hospital amid a worldwide debate over who should get experimental Ebola treatments. After holding a teleconference with medical experts around the world, the WHO declared it is ethical to use unproven Ebola drugs and vaccines in the current outbreak.
There have been stunning “firsts” in research on idiopathic pulmonary fibrosis (IPF), a mysterious disease that stiffens and stills the lungs, killing half its victims in three years. In May, results of Phase 3 clinical trials on the first two effective drugs for IPF were published in the New England Journal of Medicine (NEJM). And in June, the first paper explaining IPF was published in Science Translational Medicine.
Scientists from the University of Leeds have discovered a gene that plays a vital role in blood vessel formation, research which adds to our knowledge of how early life develops. The discovery could also lead to greater understanding of how to treat cardiovascular diseases and cancer.
Researchers have discovered a previously unknown cardiac molecule that could provide a key to treating, and preventing, heart failure. The newly discovered molecule provides the heart with a tool to block a protein that orchestrates genetic disruptions when the heart is subjected to stress, such as high blood pressure.
Wrapping wound dressings around fingers and toes can be tricky, but for burn victims, guarding them against infection is critical. Today, scientists are reporting the development of novel, ultrathin coatings called nanosheets that can cling to the body’s most difficult-to-protect contours and keep bacteria at bay.
In creating an adhesive patterned after glue produced by the lowly underwater sandcastle worm, researchers are reporting today that they may have solved the problem of premature births that sometimes result from fetal surgery. It also could open up numerous opportunities to safely perform more complex fetal surgeries in the future.
For the millions of adults and children in the U.S. who have to shun nuts to avoid an allergic reaction, help could be on the way. Scientists are now developing a method to process cashews—and potentially other nuts—that could make them safer to eat for people who are allergic to them.
A large-scale University-led study involving more than 180,000 people shows that patients treated with a drug widely prescribed for type 2 diabetes can live longer than people without the condition. The findings indicate that a drug known as metformin, used to control glucose levels in the body and already known to exhibit anticancer properties, could offer prognostic and prophylactic benefits to people without diabetes.
In the first evidence that natural selection favors an individual's infection tolerance, researchers from Princeton University and the University of Edinburgh have found that an animal's ability to endure an internal parasite strongly influences its reproductive success. The finding could provide the groundwork for boosting the resilience of humans and livestock to infection.
Boeing, South African Airways (SAA) and SkyNRG announced they are collaborating to make sustainable aviation biofuel from a new type of tobacco plant. This initiative broadens cooperation between Boeing and SAA to develop renewable jet fuel in ways that support South Africa's goals for public health as well as economic and rural development.
Scientists at Albert Einstein College of Medicine of Yeshiva University have found that bacteria that aid in digestion help keep the intestinal lining intact. The findings could yield new therapies for inflammatory bowel disease (IBD) and a wide range of other disorders.
A tick bite might make you a vegetarian, or at least make you swear off red meat. Doctors across the nation are seeing a surge of sudden meat allergies in people bitten by Lone Star ticks, which are found in the Southwest and eastern half of the U.S.
A nasal brush test can rapidly and accurately diagnose Creutzfeldt-Jakob disease (CJD), an incurable and ultimately fatal neurodegenerative disorder, according to a new study.
In the largest study of its kind, researchers suggests that in older people, not getting enough vitamin D may double the risk of developing dementia and Alzheimer’s disease.
Thinking about getting inked? Check the bottle first. The Food and Drug Administration is warning tattoo parlors, their customers and those buying at-home tattoo kits that not all tattoo ink is safe.
It's long been known that faulty BRCA genes greatly raise the risk for breast cancer. Now, scientists say a more recently identified, less common gene - called PALB2 - can do the same.
In general, our knowledge of biology—and much of science in general—is limited by our ability to actually see things. Researchers who study developmental problems and disease, in particular, are often limited by their inability to look inside an organism to figure out exactly what went wrong and when. Now, thanks to techniques developed at Caltech, scientists can see through tissues, organs, and even an entire body.
Frogs, dogs, whales, snails can all do it, but humans and primates can't. Regrow nerves after an injury, that is— while many animals have this ability, humans don't. But now, new research suggests that a small molecule may be able to convince damaged nerves to grow and effectively rewire circuits.
The relationship between saturated fat and type 2 diabetes may be more complex than previously thought, according a study that claims saturated fatty acids can be associated with both an increased and decreased risk of developing the disease, depending on the type of fatty acids present in the blood.
A team of scientists has developed an entirely non-invasive technique that provides a view of blood flow in the brain. The tool could provide powerful insights into strokes and possibly Alzheimer's disease.
Eating baked or broiled fish once a week is good for the brain, regardless of how much omega-3 fatty acid it contains, according to researchers at the University of Pittsburgh School of Medicine. The findings add to growing evidence that lifestyle factors contribute to brain health later in life.
A team of researchers, led by Professor Charles E. Wyman, at the University of California, Riverside’s Bourns College of Engineering have developed a versatile, relatively non-toxic, and efficient way to convert raw agricultural and forestry residues and other plant matter, known as lignocellulosic biomass, into biofuels and chemicals.
