Tissue stem cells can self-renew and differentiate, supplying cells necessary for tissues at various developmental stages. However, detailed analysis in vivo is difficult, so the molecular mechanisms underlying the stemness of gastric tissue stem cells have remained a mystery. Here, by using organoids that mimic tissue structure and function in vivo and GeCKO screening to inactivate arbitrary genes, Alk, Bclaf3 and Prkra have been identified as genes regulating stemness.

Cells replicate their genetic material and divide into two identical clones to perpetuate life. Some cells pause in the process with a single, undivided nucleus. When the cell resumes division after such a pause, the nucleus can become caught in the fissure, splitting violently, and killing both cells. But that is not always the case. Researchers from Hiroshima University in Japan are starting to understand how active nuclear displacement rescues cell death.

In the 1970s, physicists uncovered a problem with the Standard Model of particle physics—the theory that describes three of the four fundamental forces of nature (electromagnetic, weak, and strong interactions; the fourth is gravity). They found that, while the theory predicts that a symmetry between particles and forces in our Universe and a mirror version should be broken, the experiments say otherwise. This mismatch between theory and observations is dubbed “the Strong CP problem”—CP stands for Charge+Parity. What is the CP problem, and why has it puzzled scientists for almost half a century?
