"SENSOR: nets converge in health-care trials"
Research under way at Intel Corp. will result in new applications, new infrastructure and new business opportunities in the 21st century, including major inroads in health care services, said the company's chief technology officer, Patrick Gelsinger, in a keynote Friday (Feb. 21) at the Intel Developer Forum.

"DNA: molecules form nanodevice scaffolding"
Richard Kiehl describes using DNA's unique lock-and-key mode of chemical bonding as a molecular-circuit assembly technique that he believes will be compatible with silicon-based electronics. A patterned silicon substrate, complete with interconnection pads, carries DNA-coded "tiles" that serve as breadboards for nanocomponents. The components are measured in angstroms, enabling densities of 10 trillion bits per square centimeter (1.6 trillion bits/inch2). In the prototype system, the nanocomponents are small gold clusters that have the ability to act as single-electron memory cells.

"ADAPTIVE: optics give ground scope a steady gaze"
Michael Lloyd-Hart describes putting the final touches on a ground-based telescope that's said to offer three times better resolution than the Hubble Space Telescope. The last piece, a computer-controlled 2-foot flexible mirror, complements a 21-foot fixed primary mirror in a system that combines advanced algorithms with real-time DSP control to overcome distortions caused by Earth's atmosphere.

"NANOSCALE: waveguides provide view of single molecules"
Michael Levene describes how researchers at Cornell University perforated the top layer of a chip with two million "holes" that serve as nanoscale waveguides for a 488-nanometer laser, allowing them to film individual molecules during chemical reactions.

"SMART DUST: Companies test prototype wireless-sensor nets"
Professor David Culler describes how self-organizing wireless-sensor networks, a realization of the Pentagon's "smart-dust" concept, have reached the prototype stage worldwide. The smart sensors, or Motes, were created by the University of California at Berkeley and Intel, and are being tested out worldwide today.

"FEDERATION: Remote labs team up to simulate astronaut's heart"
Independent computer simulations running hundreds of miles apart have been harnessed to create a single, interacting supersimulation of the right and left ventricles of an astronaut's heart. The simulation tied together work done in separate labs, and represented the first successful U.S. application of an IEEE standard for organizing independent, distributed simulations into a larger, single simulation, called a federation.

"CHIPS: Lithography leap creates 20-nm chip features"
Professor James Taylor at the University of Wisconsin describes a way to create 20-nanometer chip feature sizes with 100-nm masks, giving an unexpected leap to Moore's Law and possibly extending the life of current lithography. The so-called "bright-peak technology" adjusts the phase of X-ray lithography to control diffraction � a technique that works for X-rays or even traditional optical lithography.

"NASA recruits robotics, sensors for Mars Scout mission"
Joel Levine, NASA scientist, describes the Ares unmanned flyer--one of four proposals NASA is considering for its planned Mars Scout mission slated for 2007. Ares would include robotics technology, flight instrumentation and cameras to record data that can be relayed back to Earth.
