Nanotubes refine computer memory

October 5, 2005

Nantero has succeeded in making circular wafers, 13 centimeters in diameter, that hold 10 gigabits of data and are ten times faster than flash memory.

Nantero calls its technology NRAM, nanotube-based, non-volatile random access memory.

The design involves suspending nanotube ribbons between points above a silicon chip, so that they form tiny bridges over electrodes lying below. When a charge is applied, the nanotube bridge curves… read more

PNA Molecules Could Be Used To Build Nanodevices

October 4, 2005

Carnegie Mellon University researchers have shown that the binding of metal ions can mediate the formation of peptide nucleic acid (PNA) duplexes from single strands of PNA that are only partly complementary. This result opens new opportunities to create functional, three-dimensional nanosize structures such as molecular-scale electronic circuits, which could reduce by thousands of times the size of today’s common electronic devices.

R Is for Robot

October 2, 2005

UC San Diego human-robot researchers hope to develop classroom teaching machines with a “human touch” and robotic companions that can develop personal relationships.

The Mind of an Inventor

October 2, 2005

Applied Minds, led by inventor Danny Hillis, is developing such imaginative inventions as “touch tables”: the surface of each is a high-resolution computer display showing a satellite-camera view of the world. By putting your hands on the table and spreading them, you zoom into a region, a city, a neighborhood. You can also slide your hand over the table to expose the view as captured at an earlier time.

Pill-sized camera gets to grips with your gut

October 2, 2005

Researchers have developed a radio-controlled crawling camera capsule that can move and stop on command to give doctors greater control over the images it takes, unlike existing camera capsules.

Google offers S.F. Wi-Fi — for free

October 2, 2005

Google Inc. has offered to blanket San Francisco with free wireless Internet access.

The proposal raises speculation that Google intends to create a free national Wi-Fi network.

Ray Kurzweil deciphers a brave new world

September 30, 2005 reporter Declan McCullagh quizzed Ray Kurzweil in a wide-ranging interview on the implications of the Singularity for society.

Mighty Mice Regrow Organs

September 30, 2005

Genetically altered mice discovered accidentally at the Wistar Institute in Pennsylvania have the seemingly miraculous ability to regenerate like a salamander, and even regrow vital organs.

The results stunned scientists because if such regeneration is possible in this mammal, it might also be possible in humans.

Google confirms Ames plan, Search engine plans offices, partnership with space agency

September 30, 2005

Google Inc. plans to build up to 1 million square feet of offices at NASA Ames Research Center and collaborate with the space agency on research surrounding topics such as supercomputing that could benefit everything from moon launches to online searches.

It will also involve biotechnology, information technology and nanotechnology.

Magnetic Microchips Replace Electronic Semiconductor

September 29, 2005

Researchers have created a computer by using magnetic microchips rather than semiconductor electronics.

Magnetic microchips reduce heat and are simpler and potentially cheaper to produce than electronic chips.

You Can’t Hide Your Lyin’ Brain

September 29, 2005

A scientist at the Medical University of South Carolina has found that magnetic resonance imaging machines also can serve as lie detectors, with more than 90 percent accuracy.

The MRI images show that more blood flows to parts of the brain associated with anxiety and impulse control when people lie. More blood also flows to the part of the brain handling multitasking because it is hard for people to… read more

AI systems may blow weathermen away

September 29, 2005

Weather forecasters could find themselves pushed out of a job by an artificial intelligence system designed to write clearer, less ambiguous reports.

Computer scientists at the University of Aberdeen, UK, were asked to generate an “artificial weatherperson” by operators of offshore oil rigs, who wanted more clarity in their forecasts. The vocabulary used by different forecasters can be vague and highly variable, says Ehud Reiter, who led the Aberdeen… read more
