Survivors of Hurricane Katrina have struggled with poor mental health for years after the storm, according to a new study of low-income mothers in the New Orleans area. The study's lead author, Christina Paxson of Princeton University, said that the results were a departure from other surveys both in the design and the results. The researchers were able to collect data on the participants before Katrina and nearly five years after the August 2005 storm, finding a persistence of poor mental...

Team Finds Natural Reasons Behind Nitrogen-rich Forests
2012-01-19 04:29:24

Many tropical forests are extremely rich in nitrogen even when there are no farms or industries nearby, says Montana State University researcher Jack Brookshire. It's because of biological interactions that occur naturally in the forests, Brookshire and four colleagues said in a paper they published Jan. 15 in the online version of the journal Nature Geoscience. Disputing some long-held beliefs about high nitrogen levels in forests, Brookshire said pollution isn't always the reason...

Breakthrough in coordinating electrons advances goal of quantum computing An international team of researchers including scientists at Princeton University have achieved a 100-fold increase in the ability to maintain control the spins of electrons in a solid material, a key step in the development of ultrafast quantum computers. Until recently, the best attempts at such control lasted for only a fraction of a second. But researchers Stephen Lyon and Alexei Tyryshkin have found a way to...

Alien Hunters Should Look For 'City Lights'
2011-11-04 03:42:51

In the search for extraterrestrial intelligence, astronomers have hunted for radio signals and ultra-short laser pulses. In a new paper, Avi Loeb (Harvard-Smithsonian Center for Astrophysics) and Edwin Turner (Princeton University) suggest a new technique for finding aliens: look for their city lights. "Looking for alien cities would be a long shot, but wouldn't require extra resources. And if we succeed, it would change our perception of our place in the universe," said Loeb. As with...

Assets Increase Incidence of Marriage
2011-10-07 04:51:23

A new study published in the American Journal of Sociology indicates that the incidence of marriage drops when people have no personal wealth such as a car or financial assets. The study shows that in the past few decades Americans are getting married when they are older and may forego marriage altogether. Statistics in the study indicate that between 1970 and 2000 the median age of first marriage rose by four years and the percentage of unmarrieds increased from 5 percent to 10 percent....

'Magic Carpet' Modeled After Manta Ray
2011-09-30 11:18:41

A team at Princeton University has developed a four-inch transparent magic carpet. The team, lead by graduate student Noah Jafferis, created a flying carpet based on the manta ray that utilizes piezoelectric actuators and sensors.  The electric current flexes the sheet into waves that drive tiny pockets of air across the sheet. The prototype moves at about 120 feet per hour and only travels a few inches high above the ground. Jafferis said he is working on a solar powered...

New Method Could Help Scientists Detect Dark Matter
2011-09-19 13:35:51

  Researchers from Princeton University and New York University have developed a method for detecting the collision of stars with a black hole that could help scientists uncover dark matter. Postdoctoral researchers Shravan Hanasoge of Princeton's Department of Geosciences and Michael Kesden of NYU's Center for Cosmology and Particle Physics simulated the result of primordial black hole passing through a star.  Scientists believe that primordial black holes posses the...
