New research on the novel coronavirus (COVID-19) is a multi-center study (n=101) of the relationship between chest CT findings and the clinical conditions of COVID-19 pneumonia — which determined that most patients with the disease have ground-glass opacities (GGO) (86.1%) or mixed GGO and consolidation (64.4%) and vascular enlargement in the lesion (71.3%). CT involvement […]

Ever wish your computer could think like you do or perhaps even understand you? That future may not be now, but it’s one step closer, thanks to scientists and engineers and their recent discovery of a materials-based mimic for the neural signals responsible for transmitting information within the human brain.

New research shows that animals on a prebiotic diet sleep better and are buffered from the physiological impacts of stress. The undigestible dietary compounds, found in fibrous foods and some dairy products, serve as nourishment for beneficial bacteria and influence metabolites that, in turn, impact the brain.

A new child can spark feelings of jealousy in a person who already fears being abandoned by his or her partner, research suggests. A new study found that partners who showed signs of relationship anxiety before the birth of their first child were more likely to be jealous of the child after it was born. […]

Through a technique known as DNA origami, scientists have created the fastest, most persistent DNA nano motor yet. New findings provide a blueprint for how to optimize the design of motors at the nanoscale — hundreds of times smaller than the typical human cell.

Scientists have just shown that a metabolic pathway plays a determining role in Alzheimer’s disease’s memory problems. This work also shows that supplying a specific amino acid as a nutritional supplement in a mouse model of Alzheimer’s restores spatial memory affected early. This is a promising path for reducing memory loss related to that disease. […]
