An open mind and collaborative spirit have taken Hans Clevers on a journey from medicine to developmental biology, gastroenterology, cancer, and stem cells.

Recent advances in modeling the human placenta, the least understood organ, may inform placental disorders like preeclampsia.

With human research trials resulting in dozens of successful deliveries in the US and abroad, doctors move toward offering the surgery clinically, while working to learn all they can about uterine and transplant biology from the still-rare procedure.

Studying the earliest events in visual development, Carla Shatz has learned the importance of looking at one’s data with open eyes—and an open mind.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

A T cell discovery, “hachimoji” DNA, a new species of human, and mounting fears of espionage rounded off the list this year.

When I was a high school student, I came across Erwin Schrödingers What Is Life?. I still remember my exultant reaction—a combination of adolescent pride in feeling able to understand ideas considered beyond a young person’s means, and a genuine intellectual thrill engendered by the problems that Schrödinger addressed. Upon rereading the book, it appears to me that its major value was to provoke interest in a central problem of biology. Schrödinger’s question

As more researchers flock to the popular field, observers fear a widening gap between supply and demand When scientists convene in New Orleans next week for the 33rd annual meeting of the American Society for Cell Biology (ASCB), nine symposia, 20 minisymposia, and countless informal gatherings are sure to focus on the recent achievements and continuing progress in this exciting and rapidly expanding scientific field. There is likely to be little excitement in the air, however, concerning the

Biology happens on many levels, from ecosystems to electron transport chains. These tools may help spur discoveries at all of life's scales.
