COLUMBUS, Ohio – A new study provides the first experimental evidence that the negative effects of playing violent video games can accumulate over time.
Researchers found that people who played a violent video game for three consecutive days showed increases in aggressive behavior and hostile expectations each day they played. Meanwhile, those who played nonviolent games showed no meaningful changes in aggression or hostile expectations over that period. (more…)
A key mechanism by which a bacterial pathogen causes the deadly tropical disease melioidosis has been discovered by an international team, including a University of Exeter scientist.
The findings are published in the journal Science and show how a toxin produced by the bacterium Burkholderia pseudomallei kills cells by preventing protein synthesis.
The study, led by the University of Sheffield, paves the way for the development of novel therapies to combat the bacterium which infects millions of people across South East Asia and Northern Australia.
Using intense X-rays at Diamond Light Source, the UK’s national synchrotron facility, and at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, the research team solved the structure of a protein from Burkholderia, the function of which was initially unknown. (more…)
