A new blood test would supposedly allow the detection of Alzheimer’s at a preclinical stage, at a point where treatments could be used to halt progression. Putting to one side the issue that no effective treatments currently exist, how should we judge whether this biomarker discovery is a valid or overblown claim?
Open, feed, cut. Such is the humdrum life of a motor molecule that eats and excretes damaged...
The head of the Food and Drug Administration says that the much-debated painkiller Zohydro fills...
Changing the texture and surface characteristics of a semiconductor material at the nanoscale can influence the way that neural cells grow on the material.
Women who experience gestational diabetes may face an increased risk of early heart disease later in life, even if they do not develop type 2 diabetes or metabolic syndrome subsequent to their pregnancy.
The Food and Drug Administration has approved a nerve-stimulating headband as the first medical device to prevent migraine headaches. Agency officials said the device provides a new option for patients who cannot tolerate migraine medications.
Researchers found that an electrical current can be used to orchestrate the flow of a group of cells, an achievement that could establish the basis for more controlled forms of tissue engineering and for potential applications such as “smart bandages” that use electrical stimulation to help heal wounds.
These days, it's faster and cheaper than ever to decipher a person's entire DNA. But a small U.S. study suggests that looking for disease risks that way may not be ready for the masses. For one thing, the research found that gene variants most likely linked with significant disease were the least likely to be accurately identified.
Contrary to the standard approach to treating metastatic prostate cancer, direct treatment of the primary tumor appears to prolong survival significantly, a new study suggests. The surprising findings have prompted researchers to launch clinical trials that could upend the accepted treatment of the disease.
A new lawsuit has been filed by 1,500 Haitian plaintiffs against the United Nations over a cholera outbreak that has killed thousands in the Caribbean nation.
Researchers have discovered that, by reestablishing a population of new cells in the part of the brain associated with behavior, some symptoms of Alzheimer's disease significantly decreased or were reversed altogether.
A research team is creating synthetic biofilms to better understand their formation and behavior. And, they use supercomputer models to study the molecular structure of biofilms.
An innovative hepatitis C drug that was only recently hailed as a breakthrough treatment is facing skepticism from some health care experts, as they consider whether it is worth the $1,000-a-pill price set by manufacturer Gilead Sciences.
Even the mildest form of a traumatic brain injury, better known as a concussion, can deal permanent, irreparable damage. Now, a team is using mathematical modeling to better understand the mechanisms at play in this kind of injury, with an eye toward protecting the brain from its long-term consequences.
The stigma of leprosy endures in India, even though the country has made great strides against the disease, which is neither highly contagious nor fatal. The number of new annual cases has risen slightly after years of steady decline, and medical experts say the enormous fear surrounding leprosy is hindering efforts to finally eliminate it.
Researchers have devised a new biochemical technique that will allow them, and other scientists, to delve much deeper than ever before into the specific cellular circuitry that keeps us healthy or causes disease.
Researchers have discovered that FDA-approved anti-psychotic drugs possess tumor-killing activity against the most aggressive form of primary brain cancer, glioblastoma.
Researchers have developed two inexpensive adapters that enable a smartphone to capture high-quality images of the front and back of the eye. The adapters make it easy for anyone with minimal training to take a picture of the eye and share it securely with other health practitioners or store it in the patient’s electronic record.
A small filter the size of a contact lens could possibly make life easier for some of the estimated 500 million people worldwide who suffer from itching, sneezing and a runny nose as soon as the pollen season starts.
A randomized placebo-controlled study suggests that higher levels of omega-3 DHA, the group of long-chain fatty acids found in algae and seafood, are associated with better sleep.
Breast cancer patients with high levels of vitamin D in their blood are twice as likely to survive the disease as women with low levels of this nutrient.
A visit to the dentist could one day require a detailed look at how genes in a patient's body are being switched on or off.
A second baby born with the AIDS virus may have had her infection put into remission and possibly cured by very early treatment— in this instance, four hours after birth.
A bit of pressure from a new shrinking, sponge-like gel is all it takes to turn transplanted unspecialized cells into cells that lay down minerals and begin to form teeth.
The World Health Organization says your daily sugar intake should be just 5 percent of your total calories— half of what the agency previously recommended, according to new draft guidelines published this week.
Middle-aged adults who suddenly need reading glasses, patients with TBIs and people with visual disorders may have one thing in common— "visual crowding," an inability to recognize individual items surrounded by multiple objects. This can significantly hamper reading, basic cognitive functions and processing speed.
Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in two studies.
In a new study that tracked a large sample of adults for nearly two decades, researchers have found that eating a diet rich in animal proteins during middle age makes you four times more likely to die of cancer than someone with a low-protein diet— a mortality risk factor comparable to smoking.
