Anyone who made it to high school biology has learned about mitosis, or cell division. One cell divides into two, two into four and so forth in a process designed to pass on exact copies of the DNA in chromosomes to daughter cells. New research, by a University of Georgia team, shows how the genes that control this process are regulated.
The study is important for cancer research because the regulation of cell division goes awry in tumors and normal cell growth and behavior are lost. Understanding how normal cell division is regulated will allow scientists to identify potential targets for cancer therapeutics, said Stephen Dalton, the molecular geneticist who led the UGA team.
"This is fundamental molecular cancer research," Dalton said. "One major problem in cancer is mis-segregation, [when the cells] ability to equally divide chromosomes is lost. One [daughter] cell might get too much genetic information and the other too little.

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
