Using a combination of genetic engineering and laser technology, researchers at the University of North Carolina at Chapel Hill have manipulated brain wiring responsible for reward-seeking behaviors, such as drug addiction. The work, conducted in rodent models, is the first to directly demonstrate the role of these specific connections in controlling behavior.

Rodent study identifies a key virus-sensing mechanism that is necessary for a successful immune response against infection with this particularly deadly type of virus. The research may help to guide the future design of more effective antiretroviral vaccines.

In a U.S. study, early safety tests suggested the eggs of pig whipworms have anti-inflammatory properties, reducing the size of brain lesions in MS patients.

For the first time, scientists have figured out how re-grow big chunks of human skeletal muscle by tricking the human body into accepting a biological matrix of pig proteins. If successful, this cellular regeneration method promises new life for injured war veterans and other trauma victims who are missing more than 25 percent of a limb and/or who face amputation.

Scientists have used a gene therapy tool that acts like intelligent molecular scissors to correct the key gene defect in mice with hemophilia B, a disease that can lead to uncontrolled bleeding. The intervention improved the animals’ blood clotting enough that their severe disease was reduced to a mild form.

Scientists have discovered the tool that bacteria normally found in our mouths use to invade heart tissue, causing a dangerous and sometimes lethal infection of the heart known as endocarditis.

Lithium profoundly prevents the aggregation of toxic proteins and cell loss associated with Parkinson’s disease (PD) in a mouse model of the condition.

A study in mice has pinpointed a pivotal new player in triggering the rapid antidepressant response produced by ketamine. By deactivating a little-known enzyme, the drug takes the brakes off rapid synthesis of a key growth factor thought to lift depression, say researchers supported by the National Institutes of Health.

A study led by researchers at the Joslin Diabetes Center suggests that adding the amino acid leucine to their diets may help those with pre-diabetes or metabolic syndrome.

In a study of mice, researchers have slowed an immune system attack on the ovaries. The mice developed a disorder resembling primary ovarian insufficiency (POI), a menopause-like condition that affects women under the age of 40, sometimes years or even decades before normal menopause.

Mayo Clinic investigators and collaborators from the United Kingdom cured well-established prostate tumors in mice using a human vaccine with no apparent side effects. This novel cancer treatment approach encourages the immune system to rid itself of prostate tumors without assistance from toxic chemotherapies and radiation treatments.

The findings suggest manipulating activity of PKD1, the gene causing the most common form of polycystic kidney disease, may prove beneficial in reducing cysts in both liver and kidney.

Scientists have designed a brain implant that restored lost memory function and strengthened recall of new information in laboratory rats — a crucial first step in the development of so-called neuroprosthetic devices to repair deficits from dementia, stroke and other brain injuries in humans.

Funded by the Defense Advanced Research Projects Agency (DARPA) and spurred by the return of injured Iraq and Afghanistan war veterans, researchers aim to design prostheses that will not only be able to move, but also provide amputees and quadriplegics with a sense of touch.

Scientists have figured out how ketamine works in the brain. In the process, they've uncovered a new molecular pathway involved in clinical depression.

Results of mouse research could eventually be used to treat people and prevent traumatic memories from taking over their lives — whether they are soldiers in combat or civilians caught up in a natural disaster.
