Circadian rhythms help in brain's unique process of waste removal

New research details how the complex set of molecular and fluid dynamics that comprise the glymphatic system - the brain's unique process of waste removal - are synchronized with the master internal clock that regulates the sleep-wake cycle.

New theory changes the understanding of complex social interactions

Tracking the extent to which other people think differently from yourself appears to be more relevant than understanding someone else's thoughts per se. Neuroscientists at Ghent University and the University of New South Wales (Sydney) came to this conclusion.

Novel technique to detect the fungus responsible for causing severe pneumonia

Research staff of the University of Valencia and the Foundation for the Promotion of Health and Biomedical Research of the Valencian Community, among other institutions, have developed a very sensitive and fast in-vitro method for the diagnosis of infection by Pneumocystis jirovecii, a fungus that causes severe pneumonia.

Study: BIRC2 overexpression could be a key marker for immunotherapy resistance

Johns Hopkins Medicine researchers have added to evidence that a gene responsible for turning off a cell's natural "suicide" signals may also be the culprit in making breast cancer and melanoma cells resistant to therapies that use the immune system to fight cancer.

High-pressure preconcentration devices for detecting small amounts of virus in early infections

Diagnostic devices that are used at home or in doctors' offices are often not sensitive enough to detect small amounts of a virus that might be present in samples from asymptomatic patients, which can occur in early stage COVID-19.

Surgeons use patients' own stem cells to rebuild damaged corneas

Surgeons at Massachusetts Eye and Ear have replaced the ocular surface of four patients who each experienced chemical burns to one eye by using their own stem cells taken from the other healthy eye, in a technique known as "cultivated autologous limbal epithelial cell transplantation" (CALEC).
