Three factors may predict college students' loss of self-control, WVU study finds

A West Virginia University study found that college students' initial status of self-control is partly dependent on their willingness to try new things and their maternal attachment. Students who are less interested in trying new things and have a secure attachment to their mothers tend to maintain stable control throughout the year. C...

Research establishes safe water thresholds for antimicrobials, to help mitigate resistance

Researchers developed a new framework to establish safe thresholds for antimicrobial release into the environment, addressing the global health threat of antibiotic-resistant bacteria. The framework provides guidance on risk assessment and could inform policy to reduce antimicrobial levels in water systems, helping to mitigate resistance.

Pinpointing how cancer cells turn aggressive

A team of scientists has developed a new method for tracing the lineage and gene expression patterns of metastatic cancer cells at the single-cell level. The researchers found that a spectrum of aggression exists in cancer cells, with some cells more likely to remain in place and others more likely to spread to other tissues.

Future falls risk detected by a simple bone density scan

A study published in Atherosclerosis has found that the build-up of calcium in major blood vessels is linked to a 39% higher risk of serious falls in older women. The research used bone density scans to identify abdominal aortic calcification, which can be detected early on, and may help health professionals to prevent future falls.

A new mechanism behind continuous stem cell activity in plants

Researchers identified a novel vascular cell maintenance system where BEH3 competes with other transcription factors to stabilize vascular stem cell multiplication and differentiation. They also found that BEH3 hinders the activity of other BES/BZR transcription factors, indicating its opposing function in regulating vascular stem cells.

For bay oysters, protection plus restoration creates healthiest reefs

A new study from the Smithsonian Environmental Research Center found that actively restoring oyster reefs can create healthier habitats than simply protecting them. The study used underwater videos to rate habitats and found that restored reefs earned the highest scores for oyster habitat, with 74% receiving a top ranking.

A better understanding of 'wet markets' is key to safeguarding human health, biodiversity

Researchers argue that targeting high-risk wet markets, particularly those selling live wild animals, can mitigate future infectious disease outbreaks while minimizing disruption to food supply chains. These informal markets pose little risk to human health or biodiversity, with most selling processed domesticated animals.
