Lack of computer access linked to poorer mental health in young people during COVID-19 pandemic

A recent study by University of Cambridge researchers found that lack of computer access led to poorer mental health among young people during the COVID-19 lockdowns. The team's analysis of data from 1,387 10–15-year-olds revealed that those without access to a computer experienced a more significant increase in Total Difficulties scores.

Revelations from Ryugu: Muon non-destructive analysis unveils true nature of ancient asteroid

Researchers from Osaka University have successfully detected carbon, nitrogen, and oxygen in samples from near-Earth asteroid Ryugu using muon non-destructive analysis. The findings suggest that CI chondrites may be contaminated with terrestrial materials, challenging previous understanding of the solar system's chemical compositions.

Subtropical clouds key to southern ocean teleconnections to the tropical pacific

A research team at UNIST has identified subtropical low cloud feedback as a key mechanism driving teleconnections between the Southern Ocean and tropical precipitation. Their findings suggest that this impact is stronger than previously thought, with implications for mid-latitude climate predictions.

Researchers reveal secret of ultra-slow motion of pine cones

Researchers from Chinese Academy of Sciences reveal the secret of ultra-slow motion in pine cones, attributing it to unique microtube structures that drive scale movement with humidity changes. They develop mimicking actuators enabling unperceivable motion, two orders of magnitude slower than other reported actuators.

More than one-third of insured Massachusetts individuals changed insurance type during the perinatal period

A University of Massachusetts Amherst study found that over 37% of insured Massachusetts residents experienced an insurance transition during the perinatal period. Individuals with Medicaid and Medicaid managed care were more likely to have a transition than those covered by private insurance, suggesting disruptions in continuity of care.
