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.
