A large international study questions the conventional wisdom that most people should cut back on salt, suggesting that the amount most folks consume is OK for heart health - and too little may be as bad as too much.
It has been more than 20 years since scientists discovered that mutations in the gene huntingtin cause the devastating progressive neurological condition Huntington’s disease. Surprisingly little, however, has been known about the gene’s role in normal brain activity. Now, new research shows it plays a critical role in long-term memory.
Researchers are reporting that they have developed a “self-fitting” material that expands with warm salt water to precisely fill bone defects that occur as a result of injury, birth defect or surgery to remove a tumor.
Oncologists are melding magnetic resonance imaging (MRI) technology with a traditional ultrasound prostate exam to create a three-dimensional map of the prostate that allows physicians to view growths that were previously undetectable.
A leading physician in Sierra Leone's fight against Ebola has died from the disease, an official said Wednesday, as it emerged that another top doctor had been considered to receive an experimental drug but did not get it and later died.
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.
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.
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.
The tiny addition of a chemical mark atop a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person’s brain responds to threats, according to a new study.
A large DNA analysis of people with and without pancreatic cancer has identified several new genetic markers that signal increased risk of developing the highly lethal disease, scientists report.
Researchers report that dietary capsaicin– the active ingredient in chili peppers– produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors.
New research suggests that microRNAs may be able to relay valuable information about damage to the heart: Scientists have linked an increase in certain microRNAs circulating in the blood with injury to cardiac muscle.
A study of 1,400 ancient and modern human skulls suggests that a reduction in testosterone hormone levels accompanied the development of cooperation, complex communication and modern culture some 50,000 years ago.
Scientists have discovered that a compound isolated from the plant protects cells from altered molecular pathways linked to Alzheimer’s, Parkinson’s and the neurodegeneration that often follows a stroke.
The nation's top infectious disease official says there's hope that a vaccine against Ebola will be available as early as next July. Dr. Anthony Fauci of the National Institutes of Health says such a preventive vaccine has been successfully tested with monkeys.
Scientists have long speculated that mosaicism plays a bigger role in the transmission of rare disease mutations than is currently known. Now, a study sheds new light on the frequency of mosaicism in genomic disorders and its influence on recurrence risk.
A new study has found that a peptide called caerulein can convert existing cells in the pancreas into those cells destroyed in type 1 diabetes-insulin-producing beta cells.
The Food and Drug Administration says it will begin regulating laboratory-developed tests, a growing class of medical diagnostics that have never before been subject to federal oversight.
In what is believed to be the largest genetic analysis of what triggers and propels progression of tumor growth in a common childhood blood cancer, researchers report that they have identified a possible new drug target for treating the disease.
