Wearable device reveals how seals prepare for diving

Researchers used a non-invasive device to investigate blood volume and oxygenation in freely diving harbor seals, finding that they constrict peripheral blood vessels and increase cerebral blood volume before submersion. This suggests that seals have cognitive control over their circulatory systems.

'Locking' an arthritis drug may be key to improving it

Researchers attach a removable lock to an arthritis drug to reduce systemic immune suppression and neutralization, making it safer and more effective. The modified form of the antibody shows promise in treating rheumatoid arthritis with fewer infections and less development of anti-infliximab antibodies.

Fooling nerve cells into acting normal

Researchers at the University of Missouri have made a groundbreaking discovery about how neurons function normally. By artificially augmenting the electrical signals of isolated neurons, they found that the cells can adjust to changes in their environment without significant harm. This finding could lead to new treatments for spinal co...

Shipwrecks off NC coast harbor tropical migrants

A new study by Duke University scientists reveals that tropical and subtropical fish are taking up residence on shipwrecks and other sunken structures off the North Carolina coast. The artificial reefs created by these structures serve as stepping stones for fish moving northward in search of suitable habitat.

Oxytocin could help treat alcohol use disorder

A study published in PLOS Biology found that oxytocin administration can block excess drinking in alcohol-dependent rats, suggesting a potential novel pharmaceutical intervention for treating alcohol-use disorder. Oxytocin also blocked altered GABA signaling in the brain region affected by alcohol dependence.
