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 ...

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 ...

Paired appendages—the pectoral and pelvic fins of fishes and the forelimbs and hindlimbs of tetrapods—were a major innovation in vertebrate evolution. Their emergence greatly expanded the ways vertebrates could move through ...
