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

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.

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.

Date: June 22, 1998 Insect Cell Culture Media, Suppliers of Primary Cell Culture Media Advantages for Protein Expression Studies Since the mid-1950s cultures of insects--cockroaches, fruit flies, and leafhoppers, to name a few--have been the object of quiet study by physiologists and cell biologists. But along came genetic engineering and suddenly insect cultures have been put in the spotlight since they provide advantages over both bacterial and mammalian systems for recombinant protein prod

Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?

How to make your lab less like a factory and more like a family

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

The Scientist’s annual competition uncovered a bonanza of interesting technologies that made their way onto the market and into labs this year.
