Climate modelers at the Goddard Institute for Space Studies (GISS) have succeeded in reproducing the climate changes caused by a massive freshwater pulse into the North Atlantic that occurred at the beginning of the current warm period 8,000 years ago. Their work is the first to consistently model the event and the first time that the model results have been validated by comparison to the record of climate proxies that scientists regularly use to study the Earths past.
"We only have one example of how the climate reacts to changes, the past," said Gavin A. Schmidt, a GISS researcher and co-author on the study. "If were going to accurately simulate the Earths future, we need to be able to replicate past events. This was a real test of the models skill."
The study was led by Allegra LeGrande, a graduate student in the department of earth and environmental sciences at Columbia University. The results appear in a paper being published in this weeks edition of the journal Proceedings of the National Academy of Sciences (PNAS).

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
