Researchers have developed a computerized system that can track patients’ brain activity during a coma and automatically adjust drug dosages to maintain the correct state.
Five decades of isolation, military rule and woeful health care have left Myanmar with a particularly high rate of blindness. Now, the veil of darkness is starting to lift, thanks in part to a surgical procedure that allows cataracts to be removed safely, without stitches, through two small incisions.
A bone drug already on the market for osteoporosis may kill chronic myelogenous leukemia (CML) stem cells thought to persist in the bone marrow after standard therapy, lowering the likelihood of disease recurrence, according to a new study.
Imitation may be the sincerest form of flattery for adults, but for babies it’s their foremost tool for learning. Researchers have found the first evidence revealing a key aspect of the brain processing that occurs in babies to allow this learning by observation.
Scientists have developed a new method for creating stem cells for the human liver and pancreas. This method could enable both cell types to be grown in sufficient quantities for clinical use.
A team of scientists created and characterized a new molecule, using elements of Clostridium botulinum and Clostridium tetani neurotoxins, that was able to alleviate hypersensitivity to inflammatory pain.
Research into clinical use of microbeam radiation therapy (MRT) has been limited because of the sheer size of the technology required to generate the beams. Now, researchers have developed a new microbeam emitter which has scaled down the technology, opening the doors for clinical research.
Imagine a 1950s horror movie monster— a creeping, gelatinous, gluey tangle of gunk that strangles everything around it. That’s what amyloid plaques are like when they form in body tissues.
Ten years after the SARS outbreak, scientists have uncovered genome sequences of a new virus closely related to the SARS coronavirus that erupted in Asia in 2002 to 2003, which caused a global pandemic crisis.
Doctors may one day be able to control a patient's HIV infection in a new way: injecting swarms of germ-fighting antibodies, two new studies suggest. In monkeys, that strategy sharply reduced blood levels of a cousin of HIV.
A new study clarifies the role of calcium signaling in the medically significant communication between skin cells that occurs during wound healing.
In two comprehensive studies, scientists have discovered new associations of two major type 2 diabetes risk genotypes and altered plasma concentrations of metabolic products.
Researchers have found a more accurate method to screen for bacterial meningococcal infection in its early stages, when it's hardest to detect.
Video gaming causes increases in the brain regions responsible for spatial orientation, memory formation and strategic planning, as well as fine motor skills, according to a new study.
Using an in situ sectioning electron microscope, researchers have examined the internal structure of– and interaction between– liver cells.
Blueberries are called a “superfood” for their high polyphenol content, but when baked or cooked, levels of some of these substances rise while others fall, which could alter their “super” health benefits.
A new type of “good cholesterol,” made in the lab, could one day deliver drugs to where they are needed in the body to treat disease or be used in medical imaging, according to scientists.
Growing up in poverty can have long-lasting, negative consequences for a child. But for poor children raised by parents who lack nurturing skills, the effects may be particularly worrisome, according to a new study that shows children living in poverty exhibit changes in the brain that can lead to lifelong problems.
A new study questions previous suggestions that attention deficit hyperactivity disorder (ADHD) is the result of fundamental abnormalities in dopamine transmission, and suggests that the main cause of the disorder may lie instead in structural differences in the grey matter in the brain.
Structures that put a spin on light reveal tiny amounts of DNA with 50 times better sensitivity than the best current methods, a new research collaboration has shown.
A brain chemical that desynchronizes the cells in the biological clock helps the clock adjust more quickly to abrupt shifts in daily light/dark schedules such as those that plague modern life.
Imagine significantly reducing a persistent migraine or fibromyalgia by a visit to a doctor who delivers low doses of electricity to the brain. Scientists are optimizing the next generation for such a technique, called high-definition transcranial direct current stimulation, or HD-tDCS.
In a pair of landmark studies that exploit the genetic sequencing of the “missing link” cold virus, rhinovirus C, scientists have constructed a 3-D model of the pathogen that shows why there is no cure yet for the common cold.
For nearly 300 years, investigators have known that body temperature follows a circadian, or 24-hour, rhythm, with a peak during the day and a low at night. Now, researchers explain how body temperature rhythms are synchronized while maintaining the ability to adapt to changes in environmental temperature no matter the time of day or night.
Light enhances brain activity during a cognitive task even in some people who are totally blind, according to a new study. The findings contribute to scientists' understanding of everyone's brains, as they also revealed how quickly light impacts on cognition.
