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

Tagging antibodies with rare earth metals instead of fluorescent molecules turns a veteran technique into a high-throughput powerhouse.

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.

A growing branch of research on how plants use exosomes to interact with their environment is opening up a new field of plant biology.

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.

MicroRNA plays an unexpected role in the process, researchers report in Science

Four studies identify alternative origins for cells of the developing lymphatic system, challenging the long-standing view that they all come from veins.

Z. Mourelatos et al., "miRNPs: A novel class of ribonucleoproteins containing numerous microRNAs," Genes & Development, 16[6]:720-8, March 15, 2002. "A novel ribonucleoprotein (RNP) complex in HeLa cells was identified that contains two proteins implicated in spinal muscular atrophy (SMA), eIF2C2 (a member of the Argonaute family), and numerous small RNAs ~22 nucleotides in length. The finding that microRNAs (miRNAs) associate with eIF2C2 ties together genetic findings demonstrating that Argona

Researchers are using modern experimental tools to probe the mysterious molecular pathways that lead to premature labor and birth.
