Researchers are investigating the complex relationships between the spread of the HIV virus in a population and the actual evolution of the virus within each patient’s body using a new modeling approach that distinguishes between susceptible and infected individuals, capturing the full infection history.
The deadliest brain cancer requires grueling treatment with bleak prospects for survival. Now, researchers have discovered a key component to how these aggressive tumors grow that could lead to better solutions.
People with autism are more likely to also have synesthesia, suggests new research. Synesthesia involves people experiencing a "mixing of the senses," for example, seeing colors when they hear sounds, or reporting that musical notes evoke different tastes.
The caffeine in a cup of coffee might help your small blood vessels work better, according to a new study showing that drinking a cup of caffeinated coffee significantly improved blood flow in participants' fingers.
Insomnia, the most common sleep disorder, affects up to one-third of the population in the United States. In new findings, researchers have found that some insomnia symptoms are associated with an increased risk of mortality in men.
Today's kids can't keep up with their parents. An analysis of studies on millions of children around the world finds they don't run as fast or as far as their parents did when they were young.
A new blood biomarker correctly predicted which concussion victims went on to have white matter tract structural damage and persistent cognitive dysfunction following a mild traumatic brain injury (mTBI).
Men with prostate cancer who ate a low-fat diet and took fish oil supplements had lower levels of pro-inflammatory substances in their blood and a lower cell cycle progression score— a measure used to predict cancer recurrence— than men who ate a typical Western diet, researchers found.
A research team has found that a specific chemical compound, an aldehyde, can activate UCP1, a protein known as UCP1 that enables babies or hibernating animals to keep warm without shivering, under certain conditions, and that could also trigger fat burning.
New research has found that women who have taken oral contraceptives for three or more years are twice as likely to suffer from glaucoma, one of the leading causes of blindness which affects nearly 60 million worldwide.
Researchers have now solved the structure of a key protein in the Nipah virus, which could pave the way for the development of a much-needed antiviral drug.
A world-first clinical trial being conducted in Western Australia is exploring whether testosterone and fish oil may prove to be the key in preventing or postponing Alzheimer’s disease.
Scientists have discovered that the presence of a specific protein can distinguish between prostate cancers that are aggressive and need further treatment from those that may never seriously harm the patient.
Princeton University officials decided Monday to make available a meningitis vaccine that hasn't been approved in the U.S. to stop the spread of the sometimes deadly disease on campus.
Computer engineers and hearing scientists at The Ohio State University have made a potential breakthrough in solving a 50-year-old problem in hearing technology: how to help the hearing-impaired understand speech in the midst of background noise.
Investigators have used a new sequencing method to identify a group of genes used by the brain's immune cells– called microglia– to sense pathogenic organisms, toxins or damaged cells that require their response.
Researchers have developed a new technique for fighting deadly and hard-to-treat pancreatic cancer that uses two different types of nanoparticles, the first type clearing a path into tumor cells for the second, which delivers chemotherapy drugs.
The U.S. Food and Drug Administration today approved a device to help reduce the frequency of seizures in epilepsy patients who have not responded well to medications.
A way of using nanoparticles to investigate the mechanisms underlying "mystery" cases of infertility has been developed by scientists.
Washington University School of Medicine in St. Louis now offers genetic testing to help diagnose and treat patients with heart disorders that can lead to sudden death.
The transplant anti-rejection drug rapamycin showed unexpected benefits in a mouse model of a fatal defect in the energy powerhouses of cells, the mitochondria.
For the worst cases of type 1 diabetes, islet transplantation already has freed hundreds of people from complete dependence on insulin and from life-threatening consequences of the disease. However, the procedure still is regarded as experimental by the U.S. Food and Drug Administration (FDA).
Enhanced extracts made from special antioxidants in spearmint and rosemary improve learning and memory, a study in an animal model has found.
Scientists have solved a long-standing conundrum about the immune system and in so doing may have found a new way to boost or reduce immunity therapeutically.
Friendly microbes in the intestinal tracts (guts) of healthy American children have numerous antibiotic resistance genes, according to results of a pilot study by scientists.
