SARS-CoV-2, the virus responsible for COVID-19, can linger for days in sewage and water systems and remain infectious. Researchers call for new studies to determine if current water treatment methods are efficient and effective at killing SARS-CoV-2.
Suppressing TLR4 activity following a traumatic brain injury, such as concussion, reduces excitability, and improves working memory performance up-to a month later.
The meaning of "happiness" varies greatly, depending on where in the world a person lives.
Researchers discovered how the TGF-beta protein controls the process by which hair follicles, including stem cells, divide and form new cells or orchestrate apoptosis. The findings could provide new treatment options for baldness and therapies to speed up wound healing.
PBDEs, common flame retardants found on household furniture, caused an increased risk of diabetes in mice only exposed to the chemicals through their mother's milk. In addition to increased glucose intolerance, researchers also noted higher levels of endocannabinoid in the livers of the offspring of mice exposed to PBDEs.
Male alcohol consumption before conception was linked to significant deficits in their offspring's brain development, specifically within the neocortex. For mothers-to-be who drink alcohol, the negative outcomes of prenatal alcohol exposure on fetal brain development can be reduced with choline supplementation.
Study finds olfaction plays a significant role in the motivation to exercise. Mice who were "high runners" developed genetic differences in their olfactory systems that caused them to perceive smells differently than more sedentary mice.
Preliminary results from a new model suggest the COVID-19 lockdown should last for more than six weeks. The advice is based on data which shows it takes countries almost three weeks to see a growth rate staying below 10% and doubling time over seven days. It takes a month to keep the growth rate under control and at 1%, and 45 days to achieve containment.
Astrocytes in the striatum appear to play a critical role in stuttering. Researchers found treatment with risperidone helped reduce stuttering by increasing the metabolism of striatal astrocytes.
Twin study reveals how we adapt to aging may be genetically influenced. Individual differences in blood DNA methylation are partly heritable later in life and longitudinally across a decade, researchers report.
Alterations in the excitation and inhibition balance is regulated in the developing brain by astrocytes via the ephrin-B1 protein. The loss of astrocytic ephrin-B1 alters the E/I balance by reducing inhibition, resulting in hyperactivity of neural circuits. The hyperactivity results in reduced sociability in mice.
