A research team has devised a way to use magnetic resonance relaxometry (MRR), a close cousin of magnetic resonance imaging (MRI), to detect a parasitic waste product in the blood of Malaria-infected patients.
When you accidentally touch a hot oven, you rapidly pull your hand away. Although scientists know the basic neural circuits involved in sensing and responding to such painful stimuli, they are still sorting out the molecular players. Now, researchers have made a surprising discovery about the role of a key molecule involved in pain.
It may be possible to train the brain to prefer healthy low-calorie foods over unhealthy higher-calorie foods. A brain scan study in adult men and women suggests that it is possible to reverse the addictive power of unhealthy food while also increasing preference for healthy foods.
A spinach extract containing green leaf membranes called thylakoids decreases hedonic hunger with up to 95 percent and increases weight loss by 43 percent, according to a new study.
The international group Doctor Without Borders warned Tuesday that the world is `losing the battle' against Ebola, while U.N. officials implored all countries to quickly step up their response by contributing health experts and other help.
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.
A new method for measuring and imaging how quickly blood flows in the brain could help doctors and researchers better understand how drug abuse affects the brain, which may aid in improving brain-cancer surgery and tissue engineering, and lead to better treatment options for recovering drug addicts.
Circulating tumor cell clusters- clumps of from two to 50 tumor cells that break off a primary tumor and are carried through the bloodstream- appear to be much more likely to cause metastasis than are single CTCs, according to a new study.
Federal researchers next week will start testing humans with an experimental vaccine to prevent the deadly Ebola virus. The NIH announced today that it is launching the safety trial on a vaccine developed by the agency's National Institute of Allergy and Infectious Diseases and GSK.
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.
