Antioxidant reverses most BPA-induced fertility damage in worms

Treatment with a naturally occurring antioxidant, CoQ10, restores many aspects of fertility in C. elegans worms following exposure to BPA. The findings offer a possible path toward undoing BPA-induced reproductive harms in people.

Papers that use positive words in headlines likelier to be cited

Analysis of more than 6 million clinical and life-science papers shows articles with male lead authors are up to 21 percent more likely than those with female lead authors to use language that frames their research positively, which could contribute to persistent gender gaps in pay and career advancement in life sciences and medicine.

Nervous system actively stops Salmonella from infecting body

A study in mice shows the nervous system not only detects the presence of Salmonella in the gut but actively stops the organism from infecting the body by shutting the cellular gates that allow bacteria to invade the intestine and spread beyond it.

Researchers discover what’s behind a sense of direction

Using virtual reality experiments, Harvard neuroscientists have decoded how fruit fly brains integrate visual cues for navigation. Study also sheds light on a form of short-term memory known as unsupervised learning.

Study suggests how measles wipes out body’s immune memory

A new Harvard study shows measles wipes out 11 percent to 73 percent of antibodies against an array of viruses and bacteria, depleting a child’s previous immunity, which underscores the importance of measles vaccination.

Nervous system activity might influence human longevity, neural activity

The brain’s neural activity, long implicated in disorders ranging from dementia to epilepsy, also plays a role in human aging and life span, according to research led by scientists in the Blavatnik Institute.

Gene-editing tool prevents hearing loss in mice with hereditary deafness

Scientists have used an optimized version of the CRISPR-Cas9 gene-editing system to prevent hearing loss in so-called Beethoven mice, which carry a genetic mutation that causes profound hearing loss in humans and mice alike.

Workplace wellness programs yield unimpressive results in short term

In the first major multisite randomized controlled trial of workplace wellness programs, researchers found that while they may help people change certain behaviors, they do little to improve overall health or lower health care spending.

Researchers identify pathway that drives sustained pain following injury

Harvard researchers have identified in mice a set of neurons responsible for sustained pain and pain-coping behaviors. The new study is the first one to map out how these responses arise outside the brain.

When starting school, younger children are more likely to be diagnosed with ADHD, study says

A Harvard study has found that children born in August in states with a Sept. 1 cutoff birth date for school enrollment have a 30 percent higher risk for ADHD diagnosis than peers born in September, which may reflect overdiagnosis.
