| Digital teaching: Opportunity or challenge? Posted: 22 Nov 2021 10:54 AM PST Researchers explain why digital teaching cannot replace face-to-face teaching in university education, but can certainly be seen as a complementary tool. The future of teaching and learning may lie in so-called blended learning, a mix of face-to-face and online education. |
| Posted: 18 Nov 2021 05:36 PM PST Why do we need sleep? New research takes a step towards solving this mystery by discovering a mechanism of sleep in zebrafish, with some supporting evidence in mice. |
| Scientists may need to rethink how genomics impacts risk for OCD Posted: 18 Nov 2021 05:35 PM PST Both rare and commonly observed differences in the DNA letters strung along a person's chromosomes can explain about a third of the risk for being diagnosed with obsessive-compulsive disorder (OCD), according to a new study. |

| Neurobiologists identify a new gene important for healthy daily rhythms Posted: 15 Nov 2021 12:10 PM PST A team neurobiologists has identified a new gene, called Tango10, that is critical for daily behavioral rhythms. This gene is involved in a molecular pathway by which the core circadian clock (the 'gears') controls the cellular output of the clock (the 'hands') to control daily sleep-wake cycles. While the study was done using the fruit fly Drosophila melanogaster, the findings have implications for humans and clock-related problems and disease. |
| New optical technology spotlights how memories move in mouse brains during sleep Posted: 12 Nov 2021 09:15 AM PST Scientists have used mouse brains to demonstrate a new neural-optic system to manipulate memories. The technique hinders nerve activity -- known as long-term potentiation or LTP -- which would otherwise consolidate memory during sleep. The research team illuminates mouse brains to inhibit cofilin, a protein essential for LTP. When the specific areas of the brain are irradiated twice, once immediately after the mouse learns a task and then again during sleep after learning, memory is erased. |
