Can nanopulses heal?

February 5, 2004

Exposing cells noninvasively to an extremely powerful electric field for nanoseconds might one day be used to treat cancer, speed up healing or tackle obesity.

Teams led by Vernier, Karl Schoenbach of Old Dominion University and Stephen Beebe of Eastern Virginia Medical School, both in Norfolk, Virginia, have shown that “nanopulsing” with electric fields with gradients of tens of megavolts per meter, applied for nanoseconds, can kill tumor cells… read more

NTT Develops Three-Dimensional Nanofabrication Using Electron Beam Lithography

February 4, 2004
World

NTT has created an electron-beam lithography system that enables the fabrication of 3D structures down to the 10-nanometer level.

Plans call for applying this technique to nanofabrication of semiconductors and other nanoelectronic devices.

The process achieves a resolution 100 times that of conventional methods using an optical or X-ray beam, enabling fast 3D fabrication and patterning of nanoscale devices.

US father names son ‘Version 2.0′

February 3, 2004

Jon Blake Cusack, from Holland, Michigan has named his new-born son “Jon Blake Cusack 2.0,” as if he were a software upgrade.

“There’s a lot of new features from Version 1.0 [Mr Cusack himself] with additional features from [wife] Jamie,” he said.

2003: nanotechnology in the firing line

February 3, 2004

2003 was the year when nanotechnology collided with the real world. It was a painful collision, bringing prophecies of doom, fears of hidden dangers and calls for a moratorium on nanoscience.

Living Machines

February 3, 2004

Technology and biology are converging fast. The result will transform everything from engineering to art — and redefine life as we know it.

Lung cancer cluster bombs created by researchers

February 2, 2004

“Nanoparticle cluster bombs” have proven effective in treating cancerous lung cells in vitro. They can be programmed to escape immune system surveillance like a Trojan Horse, and carry designer drugs that target cancer cells while leaving healthy cells alone.

Robots for No Man’s Land

February 2, 2004

The military is moving more machines into battle to save both money and lives. “Well before the end of the century, there will be no people on the battlefield,” said Robert Finkelstein, a professor at the University of Maryland’s School of Management and Technology.

Stryker, one of the U.S. Army’s newest infantry vehicles, is fitted with a “ladar” scanner, the equivalent of a mounted pair of eyes that see… read more

Nanotech spy eyes life inside the cell

February 2, 2004

Gold nanoparticles are giving an unprecedented picture of the chemical and physical activity in cells.

The “nano-cameras” are able to image individual viruses in living cells for the first time, at an astonishing resolution of about 30 nanometers.

Living with the Genie

February 2, 2004

Living With the Genie: Essays on Technology and the Quest for Human Mastery gives a “reasonably balanced view of the promise and risks of a variety of technologies,” says reviewer Michael A. Goldman in the Jan. 30, 2004 issue of Science magazine.

The new book from Island Press focuses mainly on GNR (genetic engineering, nanotechnology, and robotics). In one essay, Ray Kurzweil predicts that biotechnology and nanotechnology will combine… read more

For Science, Nanotech Poses Big Unknowns

February 2, 2004

The risks of nanoparticles may ultimately prove to be minor and avoidable, experts say. Nonetheless, in a move that industry supporters blame on a conflation of facts with popular fiction — such as Michael Crichton’s best-selling thriller “Prey,” in which rogue nanoparticles wreak deadly havoc — activists have begun to organize against the science.

And the first two studies to look for such problems appeared in the January issue… read more

Nanotechnology Takes On Cancer

January 30, 2004

The NIH Roadmap for Medical Research includes nanomedicine research for cancer therapy.

For example, the Center For Biologic Nanotechnology at the University of Michigan is developing dendrimers (molecules shaped like spheres and made up of nanoscale polymers in a very specific pattern) that can create smart-therapeutic nanodevices used to treat disease. One type seeks out and recognizes only cancer cells. Another type can diagnose what type of cancer it… read more

Drug may give cells a fresh start

January 30, 2004

Scripps Research Institute chemists have found a synthetic molecule named “reversine” that seems to reprogram adult cells to make them more like youthful ones. It could provide an easy source of cells to regenerate tissues damaged by disease or injury, as an alternative to ethically controversial stem cells.

Mood Ring Measured in Megahertz

January 29, 2004

Using tiny sensors, transmitters and some software, researchers at Sandia National Laboratories have turned personal computers into advanced polygraph machines that they say are capable of monitoring people’s emotions and abilities.

Mentor/PAL uses commercial face-recognition software and off-the-shelf sensors to measure muscle activity, heartbeat, blood oxygen, and breathing depth and rapidity. It provides real-time feedback to improve human performance, particularly in military or other high-risk situations.

New Conductor Guides Data Along the Fiber Optic Route

January 29, 2004

A new, extremely tiny (50 nm. or more) cable called a nanowire might be used for practical low-loss interfaces between optical fiber and the devices that process optical and electronic signals, making more compact, faster processors possible.

UTA researchers develop sensors to think smart

January 29, 2004

Researchers at University of Texas at Arlington’s College of Engineering envision a day when clothing will become a second skin. “Smart Skin” (“distributed flexible microsensor array”) bridges nanotechnology and micro-mechanical systems.

The goal is sensors that can sense touch and air flow in addition to heat. “Smart Skin” suits could warn people when they have entered an area of toxic gases. A T-shirt on a diabetic could monitor insulin… read more
