Scientists Strive to Replace Silicon With Graphene on Nanocircuitry
Tue, 15 Jun 2010 10:51:00 -0500
Scientists have made
a breakthrough toward creating nanocircuitry on graphene, widely regarded as the most promising candidate to replace silicon as the building block of transistors. They have devised a simple and quick one-step process for creating nanowires, tuning the electronic properties of reduced graphene oxide and thereby allowing it to switch from being an insulating material to a conducting material.

A team led by University of Arizona astronomer Joshua Eisner has
observed in unprecedented detail the processes giving rise to stars and planets in nascent solar systems. The discoveries lay the groundwork for probing the formation of planets with the potential for life.

Isolating a gene that allows a type of fern to tolerate
high levels of arsenic, Purdue University researchers hope to use the finding to create plants that can clean up soils and waters contaminated by the toxic metal. Photo by Jo Ann Banks, Purdue University

How is it that some people who apparently freeze to
death can be brought back to life with no long-term negative health consequences? New findings from the laboratory of Mark B. Roth, Ph.D., of Fred Hutchinson Cancer Research Center may help explain the mechanics behind this phenomenon. Photo by Tres Frazier

Mysterious Clouds Produced When Aircraft Inadvertently Cause Rain or Snow
Tue, 15 Jun 2010 10:01:00 -0500
As turboprop and jet aircraft climb or descend under certain atmospheric conditions, they can inadvertently "seed" mid-level clouds, causing narrow bands of snow or rain to develop and fall to the ground, new research finds.
Through this seeding process, the aircraft leave behind odd-shaped holes or channels in the clouds that have long fascinated the public.
The key ingredient for developing these holes in the clouds: water droplets at subfreezing temperatures, below ...

Florida State University is planning to build one of the world's most powerful mass spectrometers. The ultrahigh-field mass spectrometer, newly funded by the National Science Foundation, will allow researchers to study in ever greater detail proteins and other molecules--the nuts and bolts of biology, the environment and renewable energy--and push the boundaries of such analyses.
NSF's Division of Chemistry has dedicated $17.5 million ($15 million of this is out of American Recovery ...
