Could liposomes be the unsung heroes of the pandemic?

Liposomes may be the unsung heroes of the COVID-19 pandemic. Without the protection of these microscopic vesicles, the delicate strands of messenger RNA (mRNA) that lie at the heart of the Pfizer and Moderna COVID-19 vaccines ...

Reverse optogenetic tool developed

A new optogenetic tool, a protein that can be controlled by light, has been characterized by researchers at Ruhr-Universität Bochum (RUB). They used an opsin—a protein that occurs in the brain and eyes—from zebrafish ...

How promiscuous protein droplets regulate immune genes

Biochemists at Emory are achieving insights into how an important regulator of the immune system switches its function, based on its orientation and local environment. New research demonstrates that the glucocorticoid receptor ...

How long-known genes continue to surprise researchers

The human genome was sequenced around 20 years ago. Since then, the sequence information encoding our proteins is known—at least in principle. However, this information is not continuously stored in the individual genes, ...

How do plants balance microbial friends and foes?

Plants are constantly exposed to microbes: Pathogens that cause disease, commensals that cause no harm or benefit, and mutualists that promote plant growth or help fend off pathogens. For example, most land plants can form ...

Individual receptors caught in the act of coupling

A new imaging technique developed by scientists at Columbia University Vagelos College of Physicians and Surgeons and St. Jude Children's Research Hospital captures movies of receptors on the surface of living cells in unprecedented ...
