Discovery of a new driving force for chemical reactions

New research just published in the journal Science by a team of chemists at the University of Georgia and colleagues in Germany shows for the first time that a mechanism called tunneling control may drive chemical reactions in directions unexpected from traditional theories.

Responsible realization of nanotechnology's full potential

The White House Emerging Technologies Interagency Policy Coordination Committee (ETIPC) has developed a set of principles specific to the regulation and oversight of applications of nanotechnology, to guide the development and implementation of policies at the agency level.

EPA proposes policy on nanomaterials in pesticide products

The U.S. Environmental Protection Agency announced today it plans to obtain information on nanoscale materials in pesticide products. Under the requirements of the law, EPA will gather information on what nanoscale materials are present in pesticide products to determine whether the registration of a pesticide may cause unreasonable adverse effects on the environment and human health. The proposed policy will be open for public comment.

Rethink nanotechnology to convert a car's waste heat into electrical power

No one is happy about rising gas prices, and to make matters worse, up to 60 percent is wasted, lost as heat that pours out of the exhaust pipe. But what if some of that heat could be collected and converted back into electricity that can recharge the battery that powers the lights, wipers, power steering, or even the electric motor in a hybrid vehicle? The technology to do just that exists, but it's still a work in progress

Citrate key in bone's nanostructure

Bone is one of nature's surprising "building materials." Pound-for-pound it's stronger than steel, tough yet resilient. Scientists at the U.S. Department of Energy's Ames Laboratory have identified the composition that gives bone its outstanding properties and the important role citrate plays, work that may help science better understand and treat or prevent bone diseases such as osteoporosis.

Researchers develop biological circuit components, new microscope technique for measuring them

Electrical engineers have long been toying with the idea of designing biological molecules that can be directly integrated into electronic circuits. University of Pennsylvania researchers have developed a way to form these structures so they can operate in open-air environments, and, more important, have developed a new microscope technique that can measure the electrical properties of these and similar devices.

Water's surface not all wet

Air and water meet over most of the earth's surface, but exactly where one ends and the other begins turns out to be a surprisingly subtle question. A new study in Nature narrows the boundary to just one quarter of water molecules in the uppermost layer - those that happen to have one hydrogen atom in water and the other vibrating freely above.
