Unifying silicon- and DNA-based computing

February 20, 2012

dnaandgate

A North Carolina State University chemist has found a way to give DNA-based computing better control over logic operations.

His work could lead to interfacing DNA-based computing with traditional silicon-based computing.

The idea of using DNA molecules to perform computations is not new; scientists have been working on it for over a decade. DNA has the ability to store much more data than conventional… read more

Mac Programs That Come With Thinking Caps On

December 6, 2005

New “thinking tools” — software for storing, retrieving and generally making the best use of information — are now available on Mac computers.

They include Devon, which uses a “semantic search” process that is more sophisticated than search engines and can bring up files or passages whose meaning is related to what you are looking for, even though they do not contain the exact search terms; and Tinderbox, which… read more

A Glimpse of a Future in a New Kind of Light

February 11, 2003

Lighting experts expect the pace of change in developing light-emitting diodes to pick up as researchers shrink the chips to microscopic size, improve their already impressive energy efficiency and increase their brightness. The chips are expected to move into the general home and office lighting market as early as 2007.

The eventual result, the experts say, will be savings of billions of dollars annually in energy and maintenance costs… read more

Family Dog Cloned Thanks to Dolly Patents

The Beam of Light That Flips a Switch That Turns on the Brain

August 14, 2007

A new generation of genetic and optical technology can give researchers unprecedented power to turn on and off targeted sets of cells in the brain, and to do so by remote control.

Some day, the remote-control technology might even serve as a treatment for neurological and psychiatric disorders.

Power could cost more than servers, Google warns

December 15, 2005

“If performance per watt is to remain constant over the next few years, power costs could easily overtake hardware costs, possibly by a large margin,” Luiz Andre Barroso said in a September paper published in the Association for Computing Machinery’s Queue.

“The possibility of computer equipment power consumption spiraling out of control could have serious consequences for the overall affordability of computing, not to mention the overall health of… read more

University Of Michigan Launches Ambitious Exploration Of Inner Space

February 26, 2003

University of Michigan researchers will attempt to capture never-before-seen views of the chemical activity inside living cells in real time and 3-D.

The team will be using synthetic nanoprobes small enough to fit inside a cell without interrupting its normal functions to measure the activity of crucial metal ions like zinc and copper as the cell works. Sophisticated statistical modeling programs will be used to interpret the data.… read more

Video: Revealing the technology of invisibility

February 4, 2009

A New Scientist video shows a device created at Duke University, North Carolina, that can make objects invisible to microwaves.

The team thinks its technology could be modified to work for infrared and visible light too, making it able to hide 3D objects from human eyes.

Also shown: using cameras and a projector, Japanese researchers beam the background video onto an obstacle’s highly reflective surface, causing it… read more

Google Earth given celestial view

August 22, 2007

The Google Sky add-on to Google Earth allows astronomers to glide through images of more than one million stars and 200 million galaxies.

Optional layers allow users to explore images from the Hubble Space Telescope as well as animations of lunar cycles.

New Microsoft Patent Apps Discusses the Building of Personalized Portals

December 27, 2005

Microsoft has had an interesting patent application published descibing a system that assists users in building personalized portals.

Bio-Whatchamacallit: Tom Ridge’s ‘Crazy’ Plan to Watch the Sky for Spores

March 12, 2003

To give emergency workers the heads-up on bioterrorism attacks, researchers are monitoring the air for bioagents as well as hospitals for signs of outbreaks of nonspecific illnesses or symptoms.

Google Taking a Step Into Power Metering

February 10, 2009

Google will announce its entry Tuesday into the small but growing business of the “smart grid,” digital technologies that seek to keep the electrical system on an even keel and reduce electrical energy consumption.

Google has developed a free Web service called PowerMeter that consumers can use to track energy use in their house or business as it is consumed.

Barney Pell: Pathways to artificial intelligence

August 30, 2007

ZDNet interviewed Powerset CEO Barney Pell on how the development of machines smarter than humans will play out in coming decades, Powerset’s smarter search engine, and how natural language understanding is at an inflection point, moving out of the labs and into the world.
