Researchers at IBM claim to have cleared a major hurdle in the building of nanoscale transistors. The company has solved an interference issue which had been perplexing researchers and preventing the construction of transistors from tiny particles of graphite. The issue arises when scientists attempt to construct circuits with graphene, a 2-D grid structure constructed from carbon atoms. The electrical properties of graphene make it an ideal replacement for larger silicon transistors.

Advances in nanotechnology have given flight to some seemingly fanciful, and also alarming, projections and fictional scenarios. Yet the applications of nanotech are so diverse and far-reaching that scientists agree that the widespread ability to manipulate matter on the nano scale -- one-billionth of a meter -- opens up possibilities to completely transform every sector of the world's economic systems.

Imagine what you'd get if you crossed Gumby with a smartphone, and you've got some idea of what a new, nanotech handset from Nokia could be like. The new Morph, which was jointly developed by the Nokia Research Center and the University of Cambridge in England, is a flexible and stretchable device that can be folded into pocket size and used as a handset, or unfolded and opened up to display more detailed information.

The potential health and environmental consequences of nanotechnology are a source of greater concern to scientists than to the public at large, according to a new study. The research included a national telephone survey of American households along with a sampling of 363 leading U.S. nanotechnology scientists and engineers.

Last weekend, 150 people attended the Alcor life extension conference in Scottsdale, Ariz. The main subject was cryonics, the use of technology to cool and preserve the human body with the aim of future revival. The technology, still speculative, raises many present-world issues. In 2003, a daughter of Ted Williams attempted to stop the cryonic suspension of the Hall of Fame baseball player.

The 2007 Nobel Prize in physics has been awarded to two scientists who discovered the technology that has made today's tiny hard disk drives possible. Albert Fert of France and Peter Grünberg of Germany are the joint winners of the award for their independent discoveries of Giant Magnetoresistance, an effect in which very weak magnetic changes give rise to major differences in electrical resistance.

Clunky old batteries may soon be a thing of the past thanks to a new energy-storage device that looks and feels like a scrap of paper. Developed by a team of researchers at Rensselaer Polytechnic Institute, the nanoengineered battery is 90 percent cellulose, made up of the same plant cells used in nearly every type of paper.

President Bush signed into law Thursday the America Competes Act, designed to boost research and education in math and the sciences through a funding package of about $42 billion. The bill aims to bolster basic research in the physical sciences, to improve instruction in math at the elementary and middle-school levels, and to expand access to advanced programs for low-income students.

IBM has developed a method of assembling microchips using nanotechnology, the company stated Thursday, a potentially revolutionary process for insulating tiny wires by allowing them to assemble themselves around air gaps. This advance could make next-generation chips dramatically faster and more energy efficient, IBM said.
