| No peers, no beers: Research shows youth substance use declined during the COVID-19 pandemic Posted: 15 Jun 2022 10:08 AM PDT With stay-at-home orders during the COVID-19 pandemic, youth spent more time at home with family and were more isolated from in-person interaction with peers. Largely due to this social isolation from peers, substance use among youth declined, according to researchers. |
| Posted: 15 Jun 2022 10:08 AM PDT Scientists gained new insights into RNA-mediated regulation of proteins (riboregulation) and its role in controlling cell growth, and most importantly how undifferentiated cells (embryonic stem cells) transform into specialised cells (e.g., liver cells). They discovered this while studying how mRNA molecules bind to and regulate ENO1, an enzyme involved in glucose metabolism. This contrasts to most previous studies, which focused on how proteins regulate RNA, this one shows that an RNA regulates a protein. This new perspective on riboregulation may represent a more widespread and meaningful principle of biological control. |
