Haydeh Payami helped uncover the genetic basis of Parkinson’s disease. Now, she hopes to find new ways to treat the disease by studying the gut microbiome.

Changes in blood levels of oxytocin and adrenocorticotropic hormone and patterns of neural activity predict how much money people will donate to a cause with high accuracy.

A combination of factors, from oxytocin release as an indicator of emotional investment to cortisol and other hormones that correlate with attention, can forecast what people will do after an experience.

Suppressing the natural age-related increase in neuronal excitation lengthens the lives of worms, and there are indications that the same may be true for mice and humans.

The advisors’ recommendations follow news of ethically dubious gene-editing work carried out by He Jiankui late last year.

A perception of sustained focus may actually be the result of cycles of fluctuating rather than continuous neural activity, according to new behavioral and neurological data from studies in humans and macaques.

Researchers directly recorded neural activity in both sides of the brain’s cortex during the movement of only one arm in humans.

The hybrid cells promote tumor heterogeneity and possible metastasis, a new study in mice and humans shows.

Neurons of the embryonic subplate don’t die as scientists had thought.

Species with larger pancreatic cells tend to have shorter lives, according to a study.  

Both higher education and industry associations were advocating for a later implementation date for the Common Rule, which governs human studies.

Humans can remember new sensory information presented during REM sleep, but this ability is suppressed during deep, slow-wave slumber.

Less than half of completed stem cell studies in humans are published in peer-reviewed journals, according to an analysis of regenerative medicine trials. 

Adding RNA sequencing analysis to genomic sequencing helps scientists uncover mutations likely responsible for genetic disorders they might otherwise miss.

With lifestyles similar to our hunter-gatherer ancestors, the San people of Southern Africa are popular study subjects.

An experiment in which people pass each other initially nonrhythmic drumming sequences reveals the human affinity for musical patterns.

Neurons can continue to capture a short-term memory without continuous firing, researchers show.  

Young cells make their way to the frontal lobe to create new circuits in the brains of infants, researchers report.
