Online virtual worlds can help social movements raise awareness and create safe spaces for their members, according to a new study by an academic at the University of East Anglia (UEA).

Prozac®, the trade name for the drug fluoxetine, was introduced to the U.S. market for the treatment of depression in 1988. Researchers report that, in addition to the drug’s known action on serotonin receptors, fluoxetine could rearrange nerve fibers in the hippocampus of mouse brains.

There are currently no drugs that stop or inhibit Alzheimer's disease. Despite drug trials showing plaque reduction in the brain, the patients' cognitive function did not improve. Would the results be different if it were possible to design studies that intervene much earlier on in the disease, before cognition is affected?

For the first time, the interaction between potentiators and the protein they target at atomic resolution has been characterized. The research shows that two distinct compounds act on the same protein region – pointing to strategies for developing more effective drugs.

Researchers have shown that a protein called Ran plays a key role in the mobility of ovarian cancer cells. The team demonstrated that these cells cannot migrate from cancerous sites without the help of Ran.

Collagen powder is just as effective in managing skin biopsy wounds as primary closure with non-absorbable sutures, according to a first-of-its-kind study.

The Alberta Diabetes Institute will be at the centre of a new clinical trial for an anti-obesity drug targeting people with rare genetic conditions that contribute to their obesity.

New findings show how a genetically aberrant, fused protein promotes a rare form of liver cancer in adolescents and young adults.The team also noted that a certain mix of drugs could target the protein, and the enzymes it recruits. In the lab, this drug combination slowed down uncontrolled growth of the cancer cells.

A team has identified multiple promising new drug candidates to treat antibiotic-resistant infections, including the superbug MRSA.

Eggshells can enhance the growth of new, strong bones needed in medical procedures, a team of UMass Lowell researchers has discovered.
