Dramatic improvement in surface finishing of 3-D printing
Visual comparison of printed surface before smoothing (1), with smoothing by conventional methods (2) and by 3D-CMF (3). CMF result (a-3) is more uniform...
Simultaneous detection of multiple spin states in a single quantum dot

Why do we develop high blood pressure?
In 90-95 percent of people, high blood pressure has no identifiable cause, yet it is a risk factor for diseases of the brain, kidneys,...
Poor sleep in early childhood may lead to cognitive, behavioral problems in later years
A study finds that children ages 3 to 7 who don't get enough sleep are more likely to have problems with attention, emotional control...
Rapid blood pressure drops in middle age linked to dementia in old age
Middle-aged people who experience temporary blood pressure drops that often cause dizziness upon standing up may be at an increased risk of developing cognitive...
Increasing minimum wage would reduce teen pregnancies
A $1 increase in the minimum wage would likely reduce the U.S. adolescent birth rate by about 2 percent, according to new Indiana University...
