| Biochemists use enzymes to change how brain cells communicate with each other Posted: 13 Jun 2022 11:07 AM PDT A new study demonstrates the possibility of changing the identity of synapses between neurons, both in vitro and in vivo, through enzymatic means. The results have implications for treating brain diseases caused by malfunctions in synaptic information processing and exchange. |
| Increased overdose and mental health risks persist two years after opioid dose reduction Posted: 13 Jun 2022 09:45 AM PDT A new study suggests that the increased rates of overdose and mental health crisis observed during the first year after opioid dose tapering persist through the second year. |
| Molecule in the nervous system may hold key to treating chronic pain Posted: 13 Jun 2022 08:21 AM PDT Researchers reveal a potential new way to treat chronic pain using anti-cancer drugs rather than opioid-based pain medication. Researchers identified the existence of a molecule in the nervous system that enhances sensitivity to pain. This molecule had previously been thought to play a role in cancer growth but had never been reported in the nervous system. By targeting this molecule it may now be possible to use already existing anti-cancer drugs to block pain. |
| Study shows people 'right size' portions of high-calorie foods Posted: 13 Jun 2022 08:21 AM PDT New research has revealed that humans moderate the size of energy-rich meals they eat, suggesting people are smarter eaters than previously thought. |
| Healthy human brains are hotter than previously thought, research finds Posted: 13 Jun 2022 08:21 AM PDT New research has shown that normal human brain temperature varies much more than we thought, and this could be a sign of healthy brain function. The new study has produced the first 4D map of healthy human brain temperature. This map overturns several previous assumptions and shows the remarkable extent to which brain temperature varies by brain region, age, sex, and time of day. |
| Brain differences in pain modulation in people with self-injury behavior Posted: 13 Jun 2022 08:21 AM PDT Researchers might have found an explanation for why people with self-injury behavior generally feel less pain than others. The key seems to be a more effective pain-modulation system, a discovery that can benefit people seeking help for their self-harm. |
| Children in remote school faced more sleep, behavior and social challenges Posted: 13 Jun 2022 08:15 AM PDT Elementary school-aged children enrolled in remote learning experienced greater behavioral, learning-related, and sleep difficulties compared with children receiving in-person instruction, according to the findings of a new study. |
| Are we born with a moral compass? Posted: 09 Jun 2022 10:19 AM PDT Researchers found that preverbal infants can make and act on moral judgments about antisocial behavior in a third party. Using a new cognitive paradigm with gaze tracking, researchers were able to show that 8-month-old infants can engage in third-party punishment. This indicates that humans may have acquired morality through evolution, and opens the door for future experiments to investigate unexplored elements of infant cognition. |
| Investigators discover a 'double life' for a key Parkinson's disease protein Posted: 09 Jun 2022 10:00 AM PDT One of the hallmarks of Parkinson's disease (PD) is the accumulation in the brain of a protein known as alpha-synuclein. A new study shines new light on the role of alpha-synuclein, uncovering a new function for the protein with relevance for PD and related conditions. The team's findings are published in Cell. |
