Cell powerhouses are typically long and lean, but with brain injury such as stroke or trauma, they can quickly become bloated and dysfunctional, say scientists who documented the phenomena in real time for the first time...

Research has shown that internet addicts do not always feel guilty about their usage, and in many cases, they do not even perceive their usage as problematic. A new model could help addicts realize that their usage is a ...

Researchers have developed a new computational model of a neural circuit in the brain, which could shed light on the biological role of inhibitory neurons -- neurons that keep other neurons from firing.

The human appendix, a narrow pouch that projects off the cecum in the digestive system, has a notorious reputation for its tendency to become inflamed (appendicitis), often resulting in surgical removal. Although it is w...

A scientist discovered Dab2 more than 20 years ago and has been studying its relationship to cancer ever since. But now he's found that Dab2 has been living a secret life all along -- one that could have public health im...

The humble fruit fly has proved to be a fruitful research subject for a neuroscientist team. The collaborators' research into their behavior has helped expand our understanding of some important neurobiological connectio...

For Superman and Supergirl, it's alien DNA. For Spiderman, it's the bite. For Iron Man, it's the suit. But for some "superfluids," it's the tiny, self-propelled swimmers that are the source of their power. Self-propelled...

Sepsis should be recognized as a separate cause of illness and death around the world. This focus would help efforts to prevent sepsis by improving hygiene, nutrition and vaccination rates and also lead to timely treatme...

Researchers have identified a series of genetic variants that affect the severity of Crohn's disease, an inflammatory bowel disease -- but surprisingly, none of these variants appear to be related to an individual's risk...

Scientists have uncovered how tumors are able to grow despite significant damage to the structure and number of their chromosomes, the storage units of DNA.

A new model to predict when people are most likely to try different products has been developed by scientists. The research could help to direct public health interventions aimed at encouraging healthier choices.

As Washington grapples with the fate of the Affordable Care Act, a pair of health care researchers has proposed a new way to design health insurance plans that could win bipartisan support -- and has already started to d...

In addition to a person's race or ethnicity, where they live can matter in terms of whether they are diagnosed at a late stage for colorectal cancer, according to a recent study.

Cancer researchers have homed in on how high-dose vitamin C kills cancer cells. Vitamin C breaks down to generate hydrogen peroxide, which can damage tissue and DNA. The new study shows that tumor cells with low levels o...

Findings by a team of scientists could provide critical knowledge to attack deadly viruses transmitted by arthropods such as mosquitoes and aphids.

Even before they are born, premature babies may display alterations in the circuitry of their developing brains, according to a first-of-its kind research study.

Aminoglycosides, recommended by the World Health Organization to treat multidrug resistant tuberculosis, cause hearing loss and kidney damage in a dose dependent manner. Now, by reducing the dose in a carefully calculate...
