Image 1 - Past Disturbances Obscure Warming Impacts On Forests
2012-03-05 10:46:29

Past disturbances, such as logging, can obscure the effects of climate change on forest ecosystems. So reports a study just published in the Proceedings of the National Academy of Sciences. The paper, exploring nitrogen dynamics, found that untangling climate impacts from other factors can be difficult, even when scientists have access to decades of data on a forest's environmental conditions. Co-author Dr. Gene E. Likens of the Cary Institute comments, "Understanding how climate change is...

Storm Of The Century May Become Storm Of The Decade
2012-02-24 08:40:22

As the Earth's climate changes, the worst inundations from hurricanes and tropical storms could become far more common in low-lying coastal areas, a new study suggests. Researchers from Princeton University and the Massachusetts Institute of Technology (MIT) found that regions such as the New York City metropolitan area that currently experience a disastrous flood every century could instead become submerged every one or two decades. The researchers report in the journal Nature Climate...

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...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
