Researchers have identified a network of genes that appear to work together in determining alcohol dependence. The findings could lead to future treatments and therapies for alcoholics and possibly help doctors screen for alcoholism.
Researchers have identified what they believe to be the cells responsible for fibrosis, the buildup of scar tissue. Fibrotic diseases are estimated to be responsible for up to 45 percent of deaths in the developed world.
Researchers can now explore viruses, bacteria and components of the human body in more detail than ever before with newly developed software. The researchers demonstrated how the software, called cellPACK, can be used to model viruses such as HIV.
Anyone who has experienced Los Angeles gridlock likely can attest that traffic may cause one's blood pressure to rise. But researchers have found that, beyond the aggravation caused by fellow drivers, traffic-related air pollution presents serious heart health risks.
U.S. health officials on Tuesday released a draft of long-awaited federal guidelines on circumcision, saying medical evidence supports having the procedure done and health insurers should pay for it.
New rules this week are bringing changes to the nation's kidney transplant system that will give some patients a better shot at a longer-lasting organ, and move others up the waiting list.
Liberia and Guinea have met a Dec. 1 target for isolating 70 percent of people infected with Ebola and safely burying 70 percent of those who die but Sierra Leone has not, the World Health Organization said Monday.
Changes in brain connections visible on MRI could represent an imaging biomarker of Alzheimer's disease, according to a new study. For the new study, researchers looked at the brain's structural connectome, a map of white matter tracts that carry signals between different areas of the brain.
A breast cancer vaccine developed at Washington University School of Medicine in St. Louis is safe in patients with metastatic breast cancer, results of an early clinical trial indicate.
Mate choice is often the most important decision in the lives of humans and animals. Now, scientists have found the first evidence that birds may choose their mate through odor.
Harry Potter swoops around on his broom, faces the bully Malfoy and later runs into a three-headed dog. For scientists studying brain activity while reading, it's the perfect excerpt from the young wizard's many adventures to give their subjects.
It's a robot unlike any other: inspired by the world's fastest land animal, controlled by video game technology and packing nifty sensors — including one used to maneuver drones, satellites and ballistic missiles.
Two months ago, the WHO launched an ambitious plan to stop the deadly Ebola outbreak in West Africa, aiming to isolate 70 percent of the sick and safely Ebola 70 percent of the victims in the three hardest-hit countries by Dec. 1.
Two studies in recent weeks have found that anxiety, depression and guilt can physically change and damage the brain from preschool through adulthood.
From new marijuana strains for the holidays to gift sets and pot-and-pumpkin pies, the burgeoning marijuana industry in Colorado is scrambling to get a piece of the holiday shopping dollar.
While the turkey you eat on Thursday will bring your stomach happiness and could probably kick-start an afternoon nap, it may also save your life one day.
An interdisciplinary team of scientists has convened to map the origins of mental illnesses in the brain and develop noninvasive technologies to treat the conditions.
Google is throwing its money, brain power and technology at the humble spoon. But these spoons are a bit more than your basic utensil: Using hundreds of algorithms, they allow people with essential tremors and Parkinson's disease to eat without spilling.
The bacterium Helicobacter pylori is strongly associated with gastric ulcers and cancer. To combat the infection, researchers developed LipoLLA, a therapeutic nanoparticle that contains linolenic acid, a component in vegetable oils.
A new hybrid vehicle is under development. Its performance isn’t measured by the distance it travels, but rather the delivery of its cargo: vaccines that contain genetically engineered DNA to fight HIV, cancer, influenza and other maladies.
Clinical research is using brain imaging and drug therapy to better understand how microscopic changes in brain connectivity relate to alcohol dependence and recovery.
A team of researchers has come up with a way of greatly reducing the unpredictability of biological circuits. The team introduced a device that could ultimately allow such circuits to behave nearly as predictably as their electronic counterparts.
After more than six years of intensive effort, including repeated failures that at times made the quest seem futile, researchers have successfully converted mouse and human skin cells into pain-sensing neurons that respond to a number of stimuli.
A protein that stimulates the brain to awaken from sleep may be a target for preventing Alzheimer’s disease, according to a new study. In recent years, scientists have established links between sleep problems and Alzheimer’s.
Whether they want to or not, consumers will soon know how many calories they are eating when ordering off the menu at chain restaurants, picking up prepared foods at supermarkets and even eating a tub of popcorn at the movie theater.
