Many structures in biology are bounded by membranes, but not all of them. Droplets of a liquid called a coacervate, which form when oppositely charged molecules come together in water, have attracted attention as models for ...

Earlier this year, an outbreak of Andes hantavirus on a cruise ship, which killed three passengers and sickened 13, highlighted the lack of approved vaccines or treatments for the virus. In a study published in Nature, scientists ...

In the early 1980s, scientists observed an anomaly. Embedded within cell membranes, they identified ion channels with extraordinarily high conductance. These so-called "BK" (Big K, or Big Potassium) channels had roughly 10 ...

Every cell in the human body faces a chronic challenge: protecting its DNA. Whenever cells divide, their genetic material must be copied accurately. But DNA is continuously under attack, and when damage goes unrepaired, it ...

By turning a patient's own immune cells into stronger cancer-fighting cells, CAR T-cell therapy has transformed how some blood cancers are treated. But it's been harder to extend this approach to solid tumors, including cancer ...

As much as half of the human genome is composed of so-called "jumping genes." These DNA sequences can make copies of themselves that are inserted back into the genome at another location, playing a significant functional ...

In a new Nature Physics study, researchers found that fin regrowth in zebrafish is driven by a brief burst of growth signal at the fin tip, sized to the amount lost, which sets up gradients of Erk activity that guide the ...
