• Sugary secrets of a cancer-related protein

  15-09-2017 23:31
  The proteins in human cells are extensively decorated with different types of sugars, a phenomenon called glycosylation. These modifications greatly increase the diversity of protein structure and function, affecting how proteins fold, how they behave, and where they go in cells. New research that will be published in the Journal of Biological Chemistry on Sept. 22 demonstrates that a rare type of glycosylation profoundly affects the function of a protein important for human development and canc

• Even With Police Body-Cam Footage, Witnesses Can Be Misled

  Body-worn cameras on police are increasingly called for in the hope they might help ease heightened tensions between officers and communities. However, scientists now find that falsified police reports and personal biases may change a person's memory of such footage to see things that were not there or never happened.Cell phone videos of clashes between police and citizens, such as that involving the death of Eric Garner in 2014, have helped drive the call for body-worn cameras on police
