Study reveals the secrets of cell size control

Science
May 17 (UPI) -- New research has revealed the mechanism cells use to control their growth and maintain their size, a phenomenon known as "cell size homeostasis." "Cell size homeostasis is a fundamental biological question and to our knowledge this is the first time we finally understand its mechanistic origin," Suckjoon Jun, a biophysicist at the University of California, San Diego, said in a news release. Jun and his colleagues previously showed that cell size is controlled by something called the "adder principle." The researchers showed cells grow by a fixed added size, irrespective of their birth size. The adder principle proved cells don't control growth through a sense time and space, but it failed to explain the exact mechanisms that allows for size homeostasis. The latest resear...

Paraguay may use army to control prisons plagued by Brazilian gangs

World
March 12 (UPI) -- Paraguay is considering the use of its armed forces to control detention centers housing the Brazilian gangs leading recent prison riots in the country. Vice President Hugo Velazquez, acting on behalf of President Mario Abdo, who traveled to meet with Brazilian President Jair Bolsonaro, said officials are considering using the army to help dissuade violence.

On Monday, the group took four jail guards hostage at the Concepcion jail. Released after several minutes, one of freed...
