Your cells divided thousands of times today. Most chromosomes landed where they should, some got stuck. New research reveals how cells rescue trapped chromosomes during division, and why cancer cells often fail at it. Published in @NatureComms doi.org/10.1038/s41467…
In the 1930s, South African scientists discovered that injecting African Clawed Frogs (called Xenopus laevis) with urine from a pregnant woman would cause them to quickly lay hundreds of eggs. These frogs thus served as the first mass-scale pregnancy test. Xenopus frogs later became the first animals cloned from an adult cell (three decades before Dolly the Sheep). This is A Brief History of Xenopus, an essay adapted from our forthcoming book about the origins and future of the research laboratory.
