Silicate weathering carbon consumption rates are significantly higher during glacial periods, with an estimated 9.3% contribution to atmospheric CO2 reduction. This study reveals the mid-latitude shelf region as an active carbon sink during glacial periods.
The research team successfully controlled the emission wavelength of carbon quantum dots from UV to yellow-green using waste polyamide as a single precursor. They achieved a total tuning range of 244 nm and demonstrated that controlled defect-state engineering can systematically regulate the optical emission.
Jewish Israelis report strengthened sense of Israeli identity, while many see Israel as more Middle Eastern than European. Israelis overwhelmingly view Israel as safer for Jews than Europe, with Germany and Hungary as closest friends in Europe.
A new review of 121 studies covering nine million young people finds associations between digital media use and poor mental health, sleep, and physical activity. The authors argue for stronger regulation and governance to mitigate these harms and promote a healthier digital environment.
Researchers at the University of Birmingham have identified a critical receptor, P2X7, that drives neuroinflammation in the brain. Blocking this receptor with an existing drug may block pathways to major brain conditions, including Alzheimer's and Parkinson's diseases.
