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.
Researchers have devised a new way to understand patterns of aneuploidy in tumors and have proposed that the phenomenon is a driver of cancer, rather than a result of it.
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.
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.
A research team demonstrated, for the first time, delivery of a drug that turns off a critical gene in the aggressive and incurable glioblastoma multiforme, increasing survival rates significantly in animals with the deadly disease.
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.
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.
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.
Two subtypes of human papillomavirus (HPV) prevented by vaccines are half as likely to be found in African-American women as in white women with precancerous cervical lesions, according to researchers.
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.
Studies presented at the American College of Rheumatology annual meeting shed new light on the connection between rheumatoid arthritis and heart disease and the factors that seem to put some rheumatoid arthritis patients in greater jeopardy of heart problems.
A fine-grained scan of DNA in lung cancer cells has revealed a gene fusion– a forced merger of two normally separate genes– that spurs the cells to divide rapidly, scientists report.
Borrowing a tactic used to identify lung infections, researchers have discovered a potential method to identify traumatic brain injuries that uses positron emission tomography scans and the body’s immune response to a brain injury.
Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now, researchers have shown that these dendrites do more than relay information from one neuron to the next.
The largest international Alzheimer's disease genetics collaboration to date has found 11 new genetic areas of interest that contribute to late onset Alzheimer's Disease (LOAD).
Hunting for compounds that target the cancer stem cells of the blood cancer acute myeloid leukemia (AML) is now easier thanks to work by a team of scientists who built a new cell culture model that mimics AML in its niche in the bone marrow and makes the search for promising new drugs more effective.
Mice models of Alzheimer's treated with one abdominal injection of an antibody fragment designed by researchers showed, after only five days, improved memory and ability to learn as the result of less aggregated toxins and an increase in the number of neurons.
The considerable diversity of HIV worldwide represents a critical challenge for designing an effective HIV vaccine. Now, a scientific team has shown that bioinformatically optimized HIV vaccine antigens might be useful in the design of a global HIV vaccine.
