Chess Champion Faces Off With New Computer

January 21, 2003

On Sunday, Garry Kasparov begins a six-game $1 million match against an Israeli program, Deep Junior, the three-time world computer chess champion.

The games will be shown in real time at and

Deep Fritz’s handlers had to provide the world champion with a copy of the software and promise not to change it later. Experts say that requirement put the machine at… read more

Plasmodium Computing

August 11, 2009

A way to program a biological computer using the food-seeking behavior of the Physarum polycephalum (an amoeboid slide mold that can find the shortest way through mazes and anticipate periodic events), has been suggested by Andrew Adamatzky from University of the West of England.

Cancers inhibited by embryonic stem cell protein

March 5, 2008

Northwestern University researchers have discovered that a protein, Lefty, produced by human embryonic stem cells (hESCs) can inhibit the growth and spread of breast cancer and malignant melanoma.

Similarities between stem cells and tumors–both are self-renewing and have the capacity to give rise to different cells types–previously led the researchers to find the protein Nodal, which facilitates cell growth, and suggested that stem cells must have a way to… read more

Scientists, be on guard … ET might be a malicious hacker

November 29, 2005

Richard Carrigan, a particle physicist at the US Fermi National Accelerator Laboratory, believes the SETI@home project is putting Earth’s security at risk by distributing the signals they receive to computers all over the world.

Computers Enlisted for Bioterror Fight

February 10, 2003

Scientists hope to develop the first treatment for smallpox by harnessing the “downtime” of two million PCs around the world.

New Nanolaser Key To Future Optical Computers And Technologies

August 18, 2009

The “spaser,” the tiniest laser since its invention nearly 50 years ago, paves the way for a host of innovations, including “hyperlenses” resulting in sensors and microscopes 10 times more powerful than today’s and able to see objects as small as DNA, super-fast computers and consumer electronics that use light instead of electronic signals to process information; and more efficient solar collectors.

Spaser stands for surface plasmon amplification by… read more

Should every computer chip have a cosmic ray detector?

March 10, 2008

Intel has been awarded a US patent for building cosmic ray detectors into every chip to avoid “soft errors” caused by electrons displaced by cosmic rays.

When triggered, it could activate error-checking circuits that refresh the nearby memory, repeat the most recent actions, or ask for the last message from outside circuits to be sent again.

Exploring Caves with Hopping Microbots

December 11, 2005

NASA-funded researchers are developing “hopping microbots” capable of exploring hazardous terrain, including underground caves and one day, to search for life below the surface of Mars.

Nanotechnology: Will it be a boon — or kill us all?

February 20, 2003

The Future Dances on a Pin’s Head, a commentary by Julia A. Moore, Wilson Center Public Policy Scholar, subtitled “Nanotechnology: Will it be a boon — or kill us all?” dated November 26, 2002, argues for setting aside a portion of nanotechnology funding to investigate the implications of the technology.

Researchers grow nanowire crystals for 3-D microchips

August 27, 2009

Stanford researchers have developed a method of stacking and purifying multiple crystal layers of germanium onto silicon that may pave the way for three-dimensional microchips that produce more computing power per unit of surface area.

Movie Exec Sees ‘New Era’ in 3-D Films

March 13, 2008

DreamWorks Animation SKG Inc. chief executive Jeffrey Katzenberg promised a “new era” in moviegoing Tuesday, as Hollywood studios prepared a huge slate of 3-D movies for theaters that are increasingly going digital.

About 1,040 theater screens are now outfitted to show 3-D movies; plans call for 10,000 more theater screens to be converted to the digital technology needed to accommodate 3-D.

At least 30 more 3-D movies are… read more

New way to switch therapeutic genes ‘on’ and ‘off’

December 23, 2005

A gene therapy research team at Cedars-Sinai Medical Center has developed a new method of signaling therapeutic genes to turn “off” or “on,” a mechanism that could enable scientists to fine-tune genetic- and stem cell-based therapies so that they are safer, more controllable and more effective.

Although other similar signaling systems have been developed, the Cedars-Sinai research is the first to give physicians the flexibility to arbitrarily turn the… read more

The Liver Chip

March 5, 2003

Researchers are building a miniature human liver on a silicon chip as a realistic model of the natural organ. Mass produced, such a chip could be a boon to companies developing drugs for hepatitis and other diseases, and for scientists investigating liver cancer and gene therapy and chemical firms testing the toxicity of new materials.

Nano Printing Goes Large

September 2, 2009

The new roll-to-roll nanoimprint lithography system could be used to cheaply and efficiently churn out nano-patterned optical films to improve the performance of displays and solar cells.

IBM Develops World’s Tiniest Nanophotonic Switch to Route Optical Data Between Cores in Future Computer Chips

March 18, 2008

IBM scientists today took another significant advance towards sending information inside a computer chip by using light pulses instead of electrons by building the world’s tiniest nanophotonic switch with a footprint about 100X smaller than the cross section of a human hair (40×12 microns).

The IBM team demonstrated that their switch has several critical characteristics that make it ideally suited to on-chip applications:

  • The switch is extremely
