Molecular guardians monitor chromosomes during cell division

One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can happen if something goes wrong during cell division, and it can lead to infertility, miscarriages, birth defects, ...

Human stem cell defenses activated by irradiation, study finds

Researchers from several Russian institutes, including MIPT, have found out how prolonged exposure to ionizing radiation affects human stem cells. They discovered that it causes a cell cycle delay, which leads to faster repairs ...

How breaks in DNA are repaired

A team of researchers from the biology department at TU Darmstadt has discovered that the processes for repairing DNA damage are far more complex than previously assumed. The ends of breaks in the double helix are not just ...
