      NASA Tests Shape-Shifting Robot Pyramid For Nanotech Swarms. Like new and protective parents, engineers watched as the TETWalker robot successfully traveled across the floor at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Robots of this type will eventually be miniaturized and joined together to form "autonomous nanotechnology swarms" (ANTS) that alter their shape to flow over rocky terrain or to create useful structures like communications antennae and solar sails. This technology has the potential to directly support NASA's Vision for Space Exploration. "This prototype is the first step toward developing a revolutionary type of robot spacecraft with major advantages over current designs," said Dr. Steven Curtis, Principal Investigator for the ANTS project, a collaboration between Goddard and NASA's Langley Research Center in Hampton, Va.

      U.K.'s $38-Million Nanotech Bet. Brits appropriate funds to help commercialize nanotech, boosting the U.K.'s competitive position in the emerging market. The U.K. Department of Trade and Industry will make eight more grants totaling £20 million ($37 million) to help companies and university researchers commercialize nanotechnology research. The funds are part of a £90 million ($170 million) nanotech initiative announced almost two years ago by the DTI, the British equivalent of the U.S. Department of Commerce. Combined with millions more in public grants and private capital, the money announced Wednesday by science and innovation minister Lord Sainsbury puts the United Kingdom in a solid competitive position in the nascent nanotech market, which cuts across dozens of sectors and could be worth trillions within a decade.

      New look for nanomotors. Physicists in the US have built the first nanoelectromechanical device that exploits the effects of surface tension. The "relaxation oscillator" consists of two droplets of liquid metal on a substrate made of carbon nanotubes and can be controlled with a small applied electric field. Alex Zettl and colleagues at the University of California at Berkeley and the Lawrence Berkeley National Laboratory say the device could find use in various nanomechanical applications, including actuators and motors (B C Regan et al. 2005 Appl. Phys. Lett. 86 123119).

      Turn on the Nanotech High Beams by Mike Treder Executive Director, The Center for Responsible Nanotechnology. You're driving a car, very fast, on a poorly marked road, in the pitch-black darkness. There are no streetlights, there is no moon out tonight, the only illumination you have is your car's headlights.you're in uncharted territory; you have no roadmap, no way to know for sure where you are going.but you're driving very fast, into the pitch-black darkness. That's the state of nanotechnology today. We're advancing rapidly into uncharted territory. The changes this technology will bring may arrive sooner than we are prepared to respond effectively to them.

      Hold Still. Particles floating in a fluid jiggle constantly, an effect called Brownian motion, which makes them tricky to handle. A new trapping technique, described in the 25 March PRL, effectively cancels out the Brownian motion of a particle by continually nudging it with just the right fluid flow. The system could allow researchers to hold and manipulate smaller particles than they can with current techniques and could help them fabricate nanomachines or hold biomolecules in place while their interactions are monitored.

      Paint On The Wall TV Screens? Case Chemist To Design Chemical Building Blocks For Such Potential Use. Imagine your television or computer screen coming from a container as something to be applied to a flat surface like a wall-or, screens so flexible that they can be rolled up and put in a pocket. Those futuristic screens are closer to reality. John Protasiewicz, Case Western Reserve University professor of chemistry, plans to use funding from a special two-year, unsolicited grant for creativity from the National Science Foundation to prepare new conjugated polymers that feature novel chemical building blocks and inorganic elements. Such special plastics have potential uses in understanding how these new display devices work, and could lead to improvements in plastic display technologies.

      Nanotech Is Booming Biggest in U.S., Report Says. The science of the very small is getting big in the United States. Americans are investing more money, publishing more scientific papers and winning more patents than anyone else in the quickly growing field of nanotechnology, according to the first comprehensive federal report on the science of things only a few hundred millionths of an inch in size. But the nation's lead may be short-lived, the report warns, as Europe and Asia show evidence of gaining. (Washington Post 3/28/05) http://www.washingtonpost.com/wp-dyn/articles/A5221-2005Mar27.html

      Fate Of Nano Waste: Researchers Study How To Make Nanomaterial Industry Environmentally Sustainable. Research into making the emerging nanomaterial industry environmentally sustainable is showing promise in a preliminary engineering study conducted at the Georgia Institute of Technology and Rice University. Under the auspices of the Rice University Center for Biological and Environmental Nanotechnology (CBEN) funded by the National Science Foundation (NSF), researchers have been investigating the potential environmental impact of nanomaterial waste. Specifically, they want to know if they can predict the fate and transport of nanomaterial waste in natural systems, and whether nanomaterials will behave the same as common environmental pollutants. In addition, they want to determine if nanomaterials can be treated before they enter the environment to minimize impact. (Sciencedaily 3/29/05)

      Ceria nanoparticles catalyze reactions for cleaner-fuel future. Experiments on ceria nanoparticles may lead to catalytic converters that are better at cleaning up auto exhaust, and/or to more-efficient ways of generating hydrogen. Researchers used bright beams of x-rays at the National Synchrotron Light Source to study how their composition, structure, and reactivity changed in response to doping with zirconium in one case, and impregnation with gold in another.

      Smart Nanocarriers to Combat Tumors. IBN's technology spells hope for cancer patients who suffer from painful side-effects of chemotherapy. A 'smart' nanocarrier technology developed by a team of researchers at the Institute of Bioengineering and Nanotechnology (IBN) is set to vastly improve the way cancer patients are treated. Anticancer drugs are now being administered to patients using methods that cause the indiscriminate killing of both diseased and healthy cells. Such chemotherapy leads to side-effects, such as nausea, fatigue, and hair loss, and makes the patient weak and frail. Between 1998 and 2002, 38,447 people in Singapore were diagnosed with some type of cancer, while 20,289 died of the disease. Hence, there is a crucial need for the development of more effective cancer therapy, which not only minimizes side-effects but also directly targets diseased cells. Scientists at IBN have found a way to tackle this problem through the use of anticancer drug delivery vehicles that transport drugs only to where they are needed in the body. This method significantly reduces or even eliminates the severe side-effects typically induced by conventional chemotherapeutics.

      Human Contact Spreads PC Viruses. The federal Centers for Disease Control (CDC) and National Science Foundation (NSF) have issued a stunning joint announcement: PC viruses, worms, and spyware can now be transmitted via human contact. Researchers at St. Paul's College in Virginia have isolated roughly 100 cases of systems infected by human contact, the two agencies said at a press conference at NSF headquarters in Arlington, Virginia. The mode of transmission? Each system's user had physical contact with another user whose system was known to be infected. The level of contact was found to be as brief as a handshake. One researcher, Avril Hidokwon, said she documented a case where the Netsky.P virus spread to 12 systems via a sneeze. Scientists have long held that electronic viruses could not possibly spread unless there was some sort of digital (wired or wireless) connection between the infected PC and the victim systems (or the victim systems and servers). "What we did not account for," explained Hidokwon at the hastily organized joint press conference, "was nanotechnology." (PCmag 4/1/05) http://www.pcmag.com/article2/0,1759,1781208,00.asp
