Memory's master switch

A study published in Neuron reveals that GABA, a natural molecule in the brain, is responsible for regulating synaptic connections and facilitating the formation of new memories. The research demonstrates that variations in local GABA levels near individual synapses determine synaptic strength and heterogeneity.

Good and bad in the hands of politicians

Researchers found that right-handers favor their dominant hand for positive ideas and non-dominant hand for negative thoughts. Conversely, left-handers use their left hand for positive expressions and right hand for negative ones. These findings suggest people link 'good' with the side of their body they can use most fluently.

Vitamin D deficiency linked to arterial stiffness in black teens

A new study published in The Journal of Clinical Endocrinology & Metabolism found that vitamin D deficiency is associated with increased arterial stiffness in black teens. Researchers discovered that higher doses of vitamin D supplementation (2,000 IU) improved cardiovascular health and reduced central arterial stiffness.

Polymer passage takes time

Researchers at Rice University have developed a theoretical method to calculate the time it takes for long-chain polymers to translocate through nanopore geometries, shedding new light on their transport. The study found that polymers pass more quickly when entering a composite pore through its wide end.

Grant to revive pre-contact Chamorro fishing techniques

The University of Guam Sea Grant Extension Program aims to revive traditional Chamorro fishing practices, which were replaced by Western technology. The project will teach the community how to build and repair indigenous canoes and fish using pre-contact equipment, promoting sustainable seafood supply and cultural preservation. Environ...

Most youth hockey injuries caused by accidents, not checking, UB study shows

A new study from the University at Buffalo found that 66% of youth hockey injuries were caused by accidental hits to the boards or goal posts, while only 34% were caused by checking. The study, which analyzed data from over 3,000 players, suggests that coaches should teach players to keep their heads up and avoid looking down at the puck.

Unexpected viral 'fossils' found in vertebrate genomes

A recent study found that human and other vertebrate genomes contain ancient sequences from deadly virus families, Ebola/Marburgviruses and Bornaviruses. These integrations were likely mediated by movable elements and may provide a selective advantage to the host species, potentially protecting against future infections.

Migrating birds can't control themselves

Researchers found that migratory birds become less capable of resisting temptation, pecking at food-giving buttons without learning to stop. The study suggests that temporal fragmentation of sleep may play a role in the loss of behavioral inhibition during migration.
