High-tech solutions ease inaugural challenges
Transportation and security officials on Inauguration Day will have a centralized, consolidated stream of traffic information and other data displayed on a single screen using software developed by the University of Maryland. The Regional Integrated Transportation Information System gives officials a single real-time view far more comprehensive than previously available. The idea is to enhance officials' ability to monitor vehicular traffic, accidents, incidents, response plans, air space, weather conditions and more.

The Science Coalition applauds House economic stimulus package proposal
The Science Coalition applauds the House for recognizing the vital need to include research funding in the economic stimulus and recovery efforts. Funding for targeted federal research programs will have the immediate impact of creating jobs and stimulating economic activity in communities across the country. This is an example that we hope the Senate will eventually follow.

Spin-polarized electrons on demand
In the future spintronics could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Scientists of the Physikalisch-Technische Bundesanstalt in Germany have developed a a single electron pump, in which electrons can be injected successively, and which is able to manipulate the spin of the single electrons.

Combating infection of crops by nematodes is soon to improve
Scientists from Ghent University and VIB have succeeded in showing how nematodes are able to manipulate the transport of the plant hormone auxin in order to force the plant to produce food for them. This advancement in knowledge about this process opens new possibilities for the development of nematode-resistant plants.

U of T chemistry discovery brings organic solar cells a step closer
Inexpensive solar cells, vastly improved medical imaging techniques and lighter more flexible television screens are among the potential applications envisioned for organic electronics. Recent experiments at University of Toronto may bring these closer thanks to new insights into ways molecules absorb and move energy.

Energy-efficient water purification made possible by Yale engineers
Water and energy are two resources on which modern society depends. As demands for these increase, researchers look to alternative technologies that promise both sustainability and reduced environmental impact. Engineered osmosis holds a key to addressing both the global need for affordable clean water and inexpensive sustainable energy according to Yale researchers.

Nations that sow food crops for biofuels may reap less than previously thought
Global yields of most biofuels crops, including corn, rapeseed and wheat, have been overestimated by 100 to 150 percent or more, suggesting many countries need to reset their expectations of agricultural biofuels to a more realistic level.

Nanotech in your vitamins
The ability of the Food and Drug Administration to regulate the safety of dietary supplements using nanomaterials is severely limited by lack of information, lack of resources and the agency's lack of statutory authority in certain critical areas, according to a new expert report released by the Project on Emerging Nanotechnologies.

Story tips from the Department of Energy's Oak Ridge National Laboratory -- January 2009
A project to speed and safeguard the shipping of thousands of radioisotopes in the US and afar hits the highway this year, but researchers expect the benefits to extend well beyond. Assistance to Navistar in developing a new lightweight truck bumper that can save gasoline without compromising safety is being performed by a materials process team headed by Gail Ludtka of ORNL. Structural defects introduced into carbon nanotubes could lead the way to carbon nanotube circuits, research led by Vincent Meunier of ORNL shows.

Low-cost strategy developed for curbing computer worms
A new, cost-effective strategy to limit the spread of worms through computer networks has been developed by researchers at UC Davis and Intel Corp. The two-pronged plan compiles suspicious incoming activity from the network's computers to create an early-warning system for worm attacks. As the threat level rises and falls, an algorithm determines whether to toggle computers online or offline depending on whether the benefit of staying online outweighs the cost of worm infection, and vice versa.

Novel technique changes lymph node biopsy, reduces radiation exposure
Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients. For the first time, Washington University in St. Louis researchers Lihong Wang and Younan Xia, have used gold nanocages to map sentinel lymph nodes in a rat noninvasively using PAT. Wang's lab is the largest PAT lab in the world, credited with the invention of super-depth photoacoustic microscopy, and Xia's lab invented the gold nanocages.

Smart lighting: New LED drops the 'droop'
Researchers at Rensselaer Polytechnic Institute have developed and demonstrated a new type of light emitting diode (LED) with significantly improved lighting performance and energy efficiency. The new polarization-matched LED, developed in collaboration with Samsung Electro-Mechanics, exhibits an 18 percent increase in light output and a 22 percent increase in wall-plug efficiency.

Study: Most young violent offenders in two NYC neighborhoods have seen someone killed
More than three-quarters of young, violent offenders interviewed in two poverty-stricken New York City neighborhoods had seen someone die in a violent incident, a new study reveals. About half of them (51 percent) had been shot themselves and 78 percent said they had a close friend who died in a violent attack.

New digital map of Africa's depleted soils to offer insights critical for boosting food production
Responding to sub-Saharan Africa's soil health crisis, the International Center for Tropical Agriculture announced today an ambitious new effort to produce the first-ever, detailed digital soil map for all 42 countries of the region. This project combines the latest soil science and technology with remote satellite imagery and on-the-ground efforts to analyze thousands of soil samples from remote areas across the continent to help provide solutions for poor farmers.
