Researchers have discovered a biomarker that could assist in the early identification of people at high risk of developing severe COVID-19.

Researchers have found that a characteristic shift in bacterial community composition and function marks progression from a healthy mouth to periodontal disease.

Switchable label proteins can change their state, for example to a signal that can be read out, or upon illumination with different colors of light. Researchers at Helmholtz Munich describe their latest work in this space.

Scientists in recent years have developed “epigenetic clocks” to measure biological age. In a new study, researchers used one such clock to ask two questions: How much does chronic stress accelerate that biological clock? And are there ways to slow it down and extend a healthy lifespan?

A new study has taken a world-first molecular look at the structure of black widow venom, which contains a subclass of neurotoxins called latrotoxins.

Researchers have observed a protein called Cockayne Syndrome B (CSB) preferentially interacting with a special form of four-stranded DNA.

The cell-by-cell atlas will help in the study of eye disorders and development of cell therapy to replace damaged eye tissue.

Research shows that when cells are deprived of oxygen, another molecule called fumarate can step in and serve as a terminal electron acceptor to enable mitochondrial function in this environment.

Lassa fever is listed as a significant public health threat with high epidemic potential and no effective countermeasures. Researchers have now used structural biology to detail nine structures of the Lassa viral polymerase in different functional configurations.

Researchers report a new candidate ribonucleoside analog, 4’-fluorouridine, that has potent antiviral activity against SARS-CoV-2 and other respiratory RNA viruses in cell culture, human organoids and different animal models when administered once daily.
