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.
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.
Soybean oil, the most consumed cooking oil in the US, has been linked to neurological and metabolic alterations in mice. Soybean oil-fed mice showed decreased levels of oxytocin in the hypothalamus.
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.
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.
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.
Young mice exposed to a healthy diet and frequent exercise show lower levels of anxiety and increased brain mass as adults.
Even though people engage in seemingly impulsive decision-making, they may actually be predisposed to curtail it.
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.
Female mice exposed to PBDEs, a type of flame-retardant found on everyday household items, pass on the chemicals to their developing offspring. In female offspring, this can cause alterations in social memories and behaviors which are reminiscent of human compulsive behaviors associated with autism.
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.
Researchers have identified a specific mechanism involved in how females inherit traits. The findings could help reduce susceptibility to Fragile X and Rett syndrome, the researchers report.
