A new genetic sequencing study reveals SARS-CoV-2, the virus responsible for coronavirus, originated from a single source in Wuhan, China. However, many of the localized cases in the US show Europe as the most likely source of infection. The study also identified a SARS-CoV-2 mutation that has never been seen before, where 81 of the letters have been permanently deleted from the genome. The mutation mirrors a large deletion that occurred during the 2003 SARS outbreak. During the mid-to-late phases of the 2003 SARS infection, the accumulated mutations attenuated the virus, leaving a weakened form of infection that resulted in less severe symptoms.
Using chemogenetic methods, researchers activated neurons in the anterior insular and increased prosocial behavior in rodent models of opioid addiction.
Children as young as 18 months combine information from their own first-hand experiences and the experiences of others to decide whether to persist in trying to solve a problem.
Taking dietary choline supplements may help to protect the brain from Alzheimer's disease. Choline reduces the activation of microglia which, when overactivated, contribute to neuroinflammation and apoptosis associated with Alzheimer's. Choline also helps block the production of amyloid plaques.
Researchers have discovered six candidate biomarkers for Lyme disease. A newly developed test can help identify the disease which, until now, has been notoriously difficult to detect.
Study suggests those who feel in awe of scientific discoveries are more likely to believe in a god, while those who are more inclined to logical thinking were less likely to believe in a deity.
