study story

The size and complexity of cephalopod brain structures differ depending on the habitats the creatures occupy, a study finds.

Moving collectively on the water surface could help protect schools of fish from being eaten by predatory birds.

A study that transfused plasma from active to inactive mice suggests the protein clusterin enhances cognition.

The Scientist interviews evolutionary biologist Carles Vilà about how a large genomic inversion detected in common quail affects the birds’ physical characteristics and migratory behaviors.

Geckos injected with neural stem cells modified to block cartilage growth developed the skeletal and nervous components normally lacking from regrown tails.

A large genome-wide association study in East Asians uncovers novel genetic links to depression, calling attention to the consequences of underrepresentation of non-European groups in genetic research data.

A study of feeding behavior suggests the fish feed differently in front of their partners—a behavioral feature also found in primates.

Researchers found more than 800 sites in the genome where the twins bore the same chemical tags.

The results add to mounting evidence of microbes’ roles in tumor growth and point to the possibility of impeding malignancies by inhibiting bacteria.

A study in people fails to detect differences in the brain’s response to fear or anxiety, long thought to be controlled by different neural circuits.

Images of the players’ hearts showed signs of inflammation consistent with myocarditis, a rare but potentially fatal condition.

An unusual experiment suggests that interrupted REM sleep can interfere with the amygdala’s ability to process emotional memories overnight—in this case, the distressing memories of listening to oneself sing out of tune.

Researchers from 17 labs report low efficacy rates for the popular technique.

Genetic adaptations for human brain development also make us vulnerable to Alzheimer’s disease, according to a new study.  

Moderate ultraviolet light exposure boosts the brainpower of mice thanks to increased production of the neurotransmitter glutamate.  

A study finds two species of guenon monkeys in Tanzania have been mating and producing fertile offspring for generations.

Humans living in higher latitudes tend to have a variant of a gene involved in sensing cold temperatures, but it comes with a cost.  

The extracellular matrix appears to inhibit regeneration; but scientists debate whether heart muscle really comes back.
