Changing just one seated meeting per week at work into a walking meeting increased the work-related physical activity levels of white-collar workers by 10 minutes, according to a new study published by public health researchers with the University of Miami Miller School of Medicine.

The discovery of a totally new kind of 'mark' in human cell nucleus
A Japanese research group verified the presence of a protein modification that is a unique mark in human cell nucleus.
