A team of researchers is studying the molecular mechanisms by which ovarian cancer spreads -- or metastasizes -- to uncover new therapeutic opportunities.

A biologist helps decode the structural complexities of male butterfly ejaculate and co-evolving female reproductive tract. Findings from these biochemical relationships may help unlock certain mysteries of human infertility.

The CHD8 gene is associated with some cases of human autism. A new study shows that mice with mutated CHD8 show defects in brain development and behavioral changes, and may give insight into genetic causes of autism spectrum disorders.

A human endogenous retrovirus family, HERV-K, interferes with the replication and infectivity of HIV-1, new research concludes.

Moderate-intensity exercise can help even extremely obese older adults improve their ability to perform common daily activities and remain independent, according to researchers.

A new mobile colistin resistance gene, mcr-3, has been discovered in E. coli of pig origin. The novel mcr-3 gene was discovered when a colistin-resistant Escherichia coli isolate tested negative for both mcr-1 and mcr-2. This novel mobile colistin resistance g…

The heart is a dynamic muscle that grows and shrinks in response to stressors such as exercise and disease. The secret to its malleability lies in individual cells, which get bigger or smaller depending on the heart's needs. A new study of mouse hearts reveals…

Video assistant refereeing in soccer has to be used with caution. Researchers have shown that refs are more likely to give red when they see a foul committed in slow motion, even when a yellow card is more justifiable. This is because fouls viewed in slow moti…

Noninvasive brain stimulation and physical therapy -- alone or in combination -- improve some measures of walking ability in patients with Parkinson's disease (PD), concludes a clinical trial.

Teens expect to experience some digital forms of abuse in dating, but girls may be suffering more severe emotional consequences than boys, according to a new study.
