New research sheds light on how the rabies virus hijacks the transport system in nerve cells to reach the brain with maximal speed and efficiency.
Circulating tumor cell clusters- clumps of from two to 50 tumor cells that break off a primary...
A new method for measuring and imaging how quickly blood flows in the brain could help doctors...
Scientists have solved the mystery of why a specific signaling pathway can be associated with alcohol dependence. This signaling pathway is regulated by a gene, called neurofibromatosis type 1 (Nf1), which is linked with excessive drinking in mice.
Using an animal model, a research team has proven the efficacy of a more elegant way to treat the rare disease MPS I through direct gene transfer.
A new study revealed the brain circuit that controls how memories become linked with positive or negative emotions, and researchers found that they could reverse the emotional association of specific memories by manipulating brain cells with optogenetics.
Learning is easier when it only requires nerve cells to rearrange existing patterns of activity than when the nerve cells have to generate new patterns, a study of monkeys has found.
An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue– the bundles of cells that make movement in animals possible.
A new study combines cutting-edge methods in electrophysiology, optogenetics and behavioral analysis to reveal exactly how the motor cortex, seemingly in anticipation of movement, can tweak the volume control in the auditory cortex.
Researchers have developed algorithms to identify weak spots in tendons, muscles and bones prone to tearing or breaking. The technology one day may help pinpoint minor strains and tiny injuries in the body’s tissues long before bigger problems occur.
Researchers found that the hormone estrogen can specifically trigger brain serotonin neurons to inhibit binge eating, which affects about 5 to 10 percent of U.S. adults, in female mice.
Men who eat over 10 portions a week of tomatoes have an 18 per cent lower risk of developing prostate cancer, new research suggests. This is the first study of its kind to develop a prostate cancer "dietary index."
New evidence puts into doubt the long-standing belief that a deficiency in serotonin— a chemical messenger in the brain— plays a central role in depression.
A third top doctor has died from Ebola in Sierra Leone, a government official said Wednesday, as health workers tried to determine how a fourth scientist also contracted the disease before being evacuated to Europe.
"Do-it-yourself" blood pressure measurements and medicine changes work better than usual doctor-office care in some patients, a study of older adults in England found.
Japanese health authorities have reported the first locally transmitted case of dengue fever in the country in more than 60 years. The ministry says the case occurred in Saitama, a prefecture adjacent to Tokyo.
The presence of Clostridia, a common class of gut bacteria, protects against food allergies, a new study in mice finds. The discovery points toward probiotic therapies for this so-far untreatable condition.
Older adults losing vision as they age are more likely to face an increased mortality risk, according to new research. The researchers analyzed data from the Salisbury Eye Evaluation study that tracked the vision health of 2,520 older adults, ages 65 to 84.
Researchers have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Their device could be used to detect the extremely rare tumor cells that circulate in cancer patients’ blood.
Scientists have identified chemical changes in the DNA of patients with Crohn’s disease that could help to screen people for the disease. These changes can be detected in blood samples, opening the door to a simple test for Crohn’s disease.
The TIM family of proteins that promotes virus entry into cells also has the ability to block the release of HIV and other viruses, researchers have found.
A large new study found that when post-menopausal women stop physical activity, their odds of developing breast cancer rise. But, the study also found that breast cancer risk drops surprisingly rapidly after exercise starts.
A virus and a zebrafish are helping scientists map the living brain. The model will help show how brain wiring is laid and how it functions.
Researchers have developed a new integrated approach to pinpoint the genetic “drivers” of cancer, uncovering eight genes that could be viable for targeted breast cancer therapy.
Scientists have, for the first time, grown a complex, fully functional organ from scratch in a living animal by transplanting cells that were originally created in a laboratory.
For the 2.2 million Americans battling glaucoma, the main course of action for staving off blindness involves weekly visits to eye specialists who conttol increasing pressure within the eye. Now, a tiny eye implant could enable patients to take more frequent readings from the comfort of home.
A Liberian doctor who was among three Africans to receive an experimental Ebola drug has died, the country's information minister said Monday, as a top U.N. delegation promised more help for countries battling the virulent disease during a visit to Sierra Leone.
The American Heart Association's first policy statement on electronic cigarettes backs them as a last resort to help smokers quit. The American Cancer Society has no formal policy but quietly took a similar stance in May.
