First-borns get more quality time with parents, study shows
Joseph Price, a graduate student in economics at Cornell, has found that a first-born child receives 20-30 more minutes of quality time each day with a parent than a second-born child of the same age from a similar family.

Study finds hidden costs of hotel employee turnover
In the hotel business, 60 percent of frontline workers and 25 percent of managers leave their jobs each year, costing employers a bundle, says a new study from Cornell's School of Hotel Administration.

HIV treatments improve health, but nutritional issues remain
New studies on nutrition and HIV from researchers at Tufts University in Boston find that a high percentage of people with HIV have the same two characteristics of metabolic syndrome, and that people with HIV on HAART may be at risk for zinc deficiency.

A new study examined brain tissue acquired at autopsy and found that VENs were devastated in FTD.

Trans fat ban: Watch saturated fats and calories too
The New York City trans fat ban is a step in the right direction, but the regulation that requires some restaurants to display calories as prominently as price is just as important.

'Vortex lattices' may help explain material defects
By combining two cutting-edge laboratory creations -- optical lattices and atoms in a Bose-Einstein condensate spinning in a trap -- physicists from NIST and the University of Colorado have developed a method of visualizing defects in rotating patterns, a new method that could be used to simulate why and how defects arise in superconductors and other important materials that are difficult to study directly.

Unfolded proteins may protect cells from dying
When proteins are not properly folded, cells become stressed to a point where they may die.
