Traveling or considering a night on the town? Best time to test for COVID is right before you leave

A new study published in the International Journal of Public Health found that testing people at the door or immediately before social mixing can significantly reduce COVID-19 transmission. The research suggests that testing on the day of an event or even 12 hours prior to arrival can effectively limit the spread of the virus.

Van Andel Institute, University of Freiburg study reveals insights into enzyme that combats a common greenhouse gas

Researchers at Van Andel Institute and University of Freiburg have discovered an enzyme that can break down nitrous oxide into harmless nitrogen and water. This breakthrough could potentially combat one of the main contributors to climate change, which accounts for only 7% of greenhouse gases but has a much greater impact.

How does “learning” turn into memory”? Input type-dependent synaptic dynamics in the motor cortex during learning

The study reveals that top-down information from the higher-order motor cortex to the primary motor cortex is crucial for motor learning, while newly formed synapses in the thalamus store acquired motor memories. This challenge to the widely held view suggests a two-step process for motor skill learning.

Newly published study reports daily prune consumption preserves hip BMD in postmenopausal women

A 12-month randomized controlled trial found that daily prune consumption preserved hip bone mineral density and protected against increased fracture risk in postmenopausal women. The study suggests that prunes may serve as a food-based option to support bone health in aging women.

Western wildfire smoke plumes are getting taller

Climate change is intensifying Western US wildfire activity, resulting in taller smoke plumes and more aerosols injected into the atmosphere. The study models 4.6 million smoke plumes and finds that maximum plume height increased by an average of 320 ft per year in four regions, with some areas experiencing a 750 ft per year increase.

Gemini telescopes help uncover origins of castaway gamma-ray bursts

Astronomers have found that short gamma-ray bursts did not originate as castaways, but instead occurred in distant galaxies up to 10 billion light-years away. The discovery suggests that these events may have been more common in the past than expected and could have seeded the Universe with precious metals.

New research finds women don’t like to participate in competitive situations when deciding for themselves, but when deciding for others, they are all in

Research finds that women are less likely to engage in competitive environments when making decisions independently, but more willing to compete when making decisions on behalf of others. This disparity results in an equal representation of men and women in competitive situations.
