Moonlighting protein makes a hospital germ harmful

The Pseudomonas aeruginosa bacterium is a widespread and dangerous hospital germ. It infects the respiratory tract and lungs and possesses natural resistance to numerous antibiotics. There is an ongoing search for so-called ...

Newly discovered process brings immune cells up to speed

Cancer cells use an unusual mechanism to migrate into new tissue and form metastases there. The same process probably also keeps some immune cells on their toes. This is the result of a recent study led by the University ...

Researchers develop new tool for targeted cell control

Thanks to new RNA vaccines, we humans have been able to protect ourselves incredibly quickly from new viruses like SARS-CoV-2, the virus that causes COVID-19. These vaccines insert a piece of ephemeral genetic material into ...

The cell sentinel that neutralizes hepatitis B

The hepatitis B virus (HBV) is responsible for one of the most serious and common infectious diseases. Transmitted through biological fluids, it attacks the liver cells. The chronic form of the disease can lead to serious ...

Tiny sea creature's genes shed light on evolution of immunity

How a tiny marine invertebrate distinguishes its own cells from competitors' bears striking similarities to the human immune system, according to a new study led by University of Pittsburgh School of Medicine researchers.

Undergrad publishes theory on immune dysfunction in space

It's been known for decades that though astronauts' immune systems become suppressed in space, leaving them vulnerable to disease, the exact mechanisms of immune dysfunction have remained a mystery. Now a Cornell undergraduate ...

The origin of life in an RNA pocket

This story begins several billion years ago. There's only chemistry, no biology—that is, plenty of chemical compounds exist on Earth, but life hasn't yet emerged. Then, among myriads of randomly self-assembled chemical ...
