Start-up to use genes to build better chips

August 5, 2004

Start-up company Cambrios plans to create films or crystals that can be used in semiconductors and other components by combining various types of metals with a virus that attacks the E. coli bacteria.

Broken nerves can be fixed in a flash

November 18, 2008

Rats with breathing problems caused by damage to their nerves have had normal breathing restored by bursts of visible light aimed onto the spinal cord.

This achievement raises hopes that a miniature light source implanted near the spine might one day allow people with similar injuries to breathe normally.

A similar device might be used to relieve constriction of the bladder caused by nerve damage.

Making silicon devices responsive to infrared light

January 6, 2014

A new system developed by researchers at five institutions, including MIT, could eliminate many limitations in methods to develop detectors that are responsive to a broad range of infrared light. Such detectors could form sensitive imaging arrays for security systems, for example.

The new system works at room temperature and provides a broad infrared response, says associate professor of mechanical engineering Tonio Buonassisi.

IBM’s New Chip: Big Blue Goes Green

May 22, 2007

IBM has unveiled its new POWER6 microprocessor, which it claims is the world’s fastest chip (at 4.7 gigahertz), boasting twice the clock speed of the previous generation while consuming roughly the same amount of power.

The new IBM chip operates at some 300 gigabytes per second. IBM has also quadrupled the amount of on-chip memory, or cache, to eight megabytes. The chip is designed for higher-end servers running the… read more

Nano convergence topic of SEMI webcast

August 18, 2004

The convergence of nanotechnology and the semiconductor industry will be discussed during SEMI’s quarterly webcast Wednesday at noon EDT.

Invention: Microscopic bio-robot slaves

November 24, 2008

University of California, Berkeley scientists say it may be possible to create a new species of “biobots” — genetically engineered specialty bacteria with the kind of microscopic features needed on microprocessors, or gene chips used to test for millions of specific DNA sequences at once.

They would be controlled using light of a specific frequency. Varying the amount of light would switch the biobots on or off by activating… read more

Xerox Develops New Way to Print Invisible Ink

May 31, 2007

Xerox scientists have perfected a new method for printing hidden fluorescent wording using standard digital printing equipment, allowing for an additional layer of security to commonly printed materials such as checks, tickets, coupons, and other high-value documents.

Scientific Method Man

September 2, 2004

The “verifier” method — used by psychologist Gordon Rugg to reveal the Voynich manuscript as a hoax — may revolutionize the scientific method and help solve seemingly unsolvable mysteries, such as the origins of the universe or the cause of Alzheimer’s disease.

The new method detects erroneous reasoning based on pattern-matching, bias, lack of familiarity with other fields of science, differing definitions of key terms, and other factors. It… read more

Silver-nanowire filters provide clean water for the developing world

Stanford researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters.  The key is coating the filter fabric – ordinary cotton – with nanotubes and silver nanowires, then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world.

Instead of physically trapping bacteria as most existing filters do, the… read more

Too Little Vitamin D Puts Heart at Risk

December 3, 2008

Vitamin D deficiency increases the risk of heart disease and is linked to other, well-known heart disease risk factors such as high blood pressure, obesity, and diabetes, says researcher James H. O’Keefe, MD, director of preventive cardiology at the Mid America Heart Institute in Kansas City, Mo.

Self-assembly could simplify nanotech construction

June 8, 2007

“Molecular origami” could become the latest nanotech construction technique, thanks to a Harvard University study.

The self-assembly process might yield simpler ways to make the microscopic components required by the electronics and computing industries.

Global to Local: The Social Future as seen by six SF Writers

Cory Doctorow, Pat Murphy, Kim Stanley Robinson, Norman Spinrad, Bruce Sterling and Ken Wharton discuss the quality of life in the future.

Spin soliton could make cell phone communication more secure

September 16, 2010

Soliton (NIST)

Researchers at the National Institute of Standards and Technology (NIST) have found theoretical evidence of a new way to generate the microwave transmissions used in modern communication devices such as cell phones. Their analysis, if supported by experimental evidence, could contribute to a new generation of wireless technology that would be more secure and resistant to interference than conventional devices.

The team’s findings point toward an oscillator that would… read more

Mumbai Terrorists Relied on New Technology for Attacks

December 9, 2008

The terrorists who struck Mumbai last month stunned authorities not only with their use of sophisticated weaponry but also with their comfort with modern technology, including GPS systems, satellite phones, and Internet VoIP phones.

Atom trap is a step towards a quantum computer

June 18, 2007

A device that can hold hundreds of atoms in a 3D array, and image each one individually, may be an important stepping stone towards developing a quantum computer.
