In a new study, researchers identified the most common characteristics of 85 COVID-19 patients who died in Wuhan, China in the early stages of the coronavirus pandemic. The study reports on commonalities of the largest group of coronavirus patient deaths to be studied to date.

Abnormal blood clotting contributes to death in some patients with severe COVID-19 infections.

A newly developed blood test for Alzheimer’s disease measures a specific variant of the tau protein. Early results show the test has a good capacity to distinguish Alzheimer’s disease from other tauopathies.

New findings support the theory that impaired prefrontal control of the dopamine system is a key mechanism for the development of schizophrenia.

Researchers report that in depressed individuals there are increased amounts of an unmodified structural protein, called tubulin, in lipid rafts — fatty sections of a cell membrane — compared with non-depressed individuals.

A new genetics test for COVID-19 has been developed by an international team of researchers. 

Genetic variability in the human immune system may affect susceptibility to, and severity of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease (COVID-19).

Researchers have developed a new approach to prevent amyloid plaque formation by engineering a nanodevice that captures the peptides before they can assemble.

A new study puts into question conventional belief that the eyes communicate with the brain exclusively via one signaling pathway. Researchers have identified a subset of retinal neurons that sends inhibitory signals to the brain. This subset of neurons is also involved in the synchronization of circadian rhythms to light/dark cycles and pupil constriction to bright light intensity.

Finally, this week, a new study sheds light on the role brain insulin plays in weight and visceral fat accumulation.
