      Dancing lasers levitate carbon nanotubes. For the first time, carbon nanotubes have been picked up and moved with a laser beam. The trick may finally offer engineers who want to build microchips based on nanotube components a way to move the diminutive devices into place...The technique exploits the ability of a laser beam to trap small particles, so that when the beam moves, the particles move with it. Biologists already use optical trapping to grab single cells - to separate out a single red blood cell for use in research on sickle cell anemia or malaria therapies, for instance.

      Scientist Sees Space Elevator in 15 Years. President Bush wants to return to the moon and put a man on Mars. But scientist Bradley C. Edwards (Scientific Research in Fairmont, W.Va. NASA) has an idea that's really out of this world: an elevator that climbs 62,000 miles into space. Edwards thinks an initial version could be operating in 15 years, a year earlier than Bush's 2020 timetable for a return to the moon. He pegs the cost at $10 billion, a pittance compared with other space endeavors...Edwards' elevator would climb on a cable made of nanotubes - tiny bundles of carbon atoms many times stronger than steel. The cable would be about three feet wide and thinner than a piece of paper, but capable of supporting a payload up to 13 tons. The cable would be attached to a platform on the equator, off the Pacific coast of South America where winds are calm, weather is good and commercial airplane flights are few. The platform would be mobile so the cable could be moved to get out of the path of orbiting satellites. (Yahoo 6/26/04)

      Wireless nanocrystals efficiently radiate visible light. A wireless nanodevice that functions like a fluorescent light - but potentially far more efficiently - has been developed in a joint project between the National Nuclear Security Administration's Los Alamos and Sandia national laboratories. The experimental success, reported in the June 10 issue of Nature, efficiently causes nanocrystals to emit light when placed on top of a nearby energy source, eliminating the need to put wires directly on the nanocrystals.

      Indian doctor duo make DNA horoscopes at birth. doctor duo from Trivandrum have developed a technique to map the DNA sequencing of human beings so as to predict their future tendencies and also help fight diseases. Ajit Kumar and Arun Kumar, both genetic experts from the city's main state-run hospitals, have developed the "Nano Geneseq Chip", which analyses the entire future genetic proposition of a human at birth itself. In layman terms the computer can, to almost 100 percent accuracy, predict how a child will grow-right from its height, color and other physical attributes to his eating habits and even romantic tendencies. Named 'NANOGENESEQ', the chip analyses the DNA samples of newborns, taken either from blood, spinal cord or saliva, effectively making a 'genetic horoscope' of the baby.

      Oregon Team Uses DNA as Template for Organizing Nanoparticles. Researchers at the University of Oregon's Oregon Nanoscience and Microtechnologies Institute (ONAMI) are now able to control precisely the spacing between nanoparticles, a key advance in the genesis of a new class of nanoscale electronics and optics...Using DNA as a template, the UO team has hit upon a convenient and reliable method to organize small gold nanoparticles into linear chains with precisely controlled interparticle spacing over a range of 1.5 to 2.8 nanometers. Controlling the magnitude and precision of the particle spacing is essential for creating electronic and optical applications of nanostructures. (Nanoelectronicsplanet.com 6/10/04)

      X-Rayed Movie. A research team has produced the fastest movies ever made of electron motion. Created by scattering x rays off of water, the movies show electrons sloshing in water molecules, and each frame lasts just 4 attoseconds (quintillionths of a second). The results, published in the 11 June PRL, could let researchers "watch" chemical reactions even faster than those viewable with today's "ultrafast" pulsed lasers. X rays can reveal atomic-scale spatial details in liquids and solids because their wavelengths are as short as the distances between atoms. Experiments typically involve aiming an x-ray beam at a sample and measuring the intensity of scattered x rays at each angle around the sample. In so-called inelastic x-ray scattering, researchers also measure the energy of the scattered rays, since x rays sometimes lose energy as they ricochet off of electrons. In theory, the scattering angles lead to nanoscale still pictures, while the energy loss data tell researchers how the pictures change with time. (Physical Review Focus 6/26/04)

      3-D Chemistry Builds Complex Micro-Structures. "We believe this technique provides a real competitive advantage for making complicated 3-D microstructures." That's Georgia Institute of Technology Researcher Seth Marder describing what he terms "a disruptive platform technology that we believe will provide broad new capabilities." Marder, also a professor at Georgia Tech's School of Chemistry and Biochemistry, says the technique could compete with existing processes for fabricating many microfluidic devices. He also cites such things as photonic bandgap structures, optical storage devices, photonic switches and couplers, sensors, actuators, micromachines -- even scaffolds for growing living tissues...Also demonstrated: the fabrication of tiny silver wires from patterns written in materials containing silver nanoparticles and ions.

      NASA Lockheed Martin Form Nanotechnology Partnership. NASA Ames Research Center, Moffett Field, Calif., and the Lockheed Martin Advanced Technology Center, Palo Alto, Calif., are launching a new collaborative effort to pursue innovative nanotechnology research to help achieve the nation's Vision for Space Exploration through development of advanced aerospace systems. Nanotechnology is the ability to control or manipulate matter on the atomic scale, making it possible to create structures, devices and systems that have novel properties and functions because of their small size: 1/1000th the diameter of a human hair. "Nanoscience has the potential to both increase capability and decrease weight, which reduces cost," said NASA Ames Center Director G. Scott Hubbard. "Future developments could lead to improved thermal and radiation protection and new sensors that could monitor the environment as well as detect the fingerprints of life."(NASA news 6/22/04) http://amesnews.arc.nasa.gov/releases/2004/04_60AR.html

      Nano Killers Aim at Mini Tumors. A company called Kereos is developing a pair of nanotechnologies to identify tumors that measure just 1 mm in diameter, then kill them with a tiny but precise amount of a chemotherapy drug. The technologies, if approved by the Food and Drug Administration, would not only find cancers in their earliest stages before they can do damage or spread, but also deliver a small amount of a drug targeted directly at tumors, which would cause little or no side effects. The technologies are in the early stages of development. The diagnostic tool will enter human trials in 2005, and the therapeutic tool should follow six months behind, according to company officials. "What's really neat about this pair is they both track the same biomarker," said Al Beardsley, president and CEO of Kereos in St. Louis. "We're using it as a signpost to say, 'Hey there's a tumor over there.' And then as a therapeutic target." Wired 6/22/04) http://www.wired.com/news/medtech/0,1286,63933,00.html?tw=wn_tophead_2

      Clothes launder own fabric. In the classic 1951 film, The Man in the White Suit, Alec Guinness played a scientist who invents a fabric that never gets dirty or wears out. A chemist's pipe dream perhaps, but the prospect of self-cleaning clothes might be getting closer. Scientists have invented an efficient way to coat cotton cloth with tiny particles of titanium dioxide. These nanoparticles are catalysts that help to break down carbon-based molecules, and require only sunlight to trigger the reaction. The inventors believe that these fabrics could be made into self-cleaning clothes that tackle dirt, environmental pollutants and harmful microorganisms. (Nature 6/14/04)

      New version of nanotechnololgy. In my previous column, I wrote about a NASA study that suggests self-replicating nanomachines are indeed possible. These bacteria-size robots, first envisioned by nanotechnology pioneer Eric Drexler, would be used to construct materials and products from the bottom up, one atom or molecule at a time...But in a new article in the journal Nanotechnology, Drexler and protege Chris Phoenix write that such nanobots are unnecessary for successful molecular manufacturing. I asked Phoenix what this updated version of nanomanufacturing would look like... (USNews 6/15/04) http://www.usnews.com/usnews/tech/nextnews/archive/next040615.htm

      Do the Nano-Locomotion. Like a futuristic submarine, a newly designed nanomachine would thrust itself through fluid using an unusual type of propulsion. In the June Physical Review E a research team proposes a simple, sphere-and-rod device that swims by changing its length along only one dimension. Its simplicity may make it attractive to engineers, who could use the "swimmer" to move nano-cargo through liquid environments, such as water or a bloodstream.
