The Future of Electronic Paper

October 17, 2007

Electronic paper is now closer than ever to changing the way we read, write, and study — a revolution so profound that some see it as second only to the invention of the printing press in the 15th century.

Made of flexible material, requiring ultra-low power consumption, cheap to manufacture, and most important, easy and convenient to read, e-papers of the future are just around the corner, with the… read more

For Simpler Robots, a Step Forward

February 24, 2005

New passive-dynamic robots depend on simple mechanics instead of complex, real-time electronic calculating power for their humanlike gait and use a fraction of the power.

The concepts may be useful in designing prosthetic limbs.

Scorn over claim of teleported DNA

January 13, 2011

Luc Montagnier, who shared theĀ Nobel prize for medicine in 2008 for his part in establishing that HIV causes AIDS, says he has evidence that DNA can send spooky electromagnetic imprints of itself into distant cells and fluids. If that wasn’t heretical enough, he also suggests that enzymes can mistake the ghostly imprints for real DNA, and faithfully copy them to produce the real thing. In… read more

Molecular switches a step closer to building a computer from the bottom up

October 29, 2001

UCLA researchers have moved an important step closer to building a computer from the bottom up: They have attached molecular switches on a grid as small as 50 nanometers.
The team has developed a 16-bit memory circuit that uses molecular switches that “work pretty well” on traditional wiring, said James Heath, UCLA chemistry and biochemistry professor and co-scientific director of the California NanoSystems Institute. The process uses chemical assembly and… read more

Memristor chip could lead to faster, cheaper computers

March 18, 2009

A University of Michigan electrical engineer has built the first array of nanoscale memristors, allowing for it to store up to 1 kilobit of information.

Memisters could open the door to universal memory. Memristor memory is non-volatile, the density of a memristor-based memory chip could be at least 10 times higher than current transistor-based chips, and you could save data to a memristor memory 1000 times faster than saving… read more

The Talk of the Town: You

October 29, 2007

The old binary view of privacy–total transparency vs. total privacy–is too blunt and dysfunctional to address privacy in the Internet era.

The Future of Reputation: Gossip, Rumor, and Privacy on the Internet, by Daniel J. Solove, associate professor of law at the George Washington University Law School, offers alternatives.

Biotech Takes on New Industries

March 11, 2005

Biotech is making inroads in chemical, fuel, oil, plastics, detergents, textiles, and other industrial areas.

Football shirt with on-board computer

November 28, 2001

Football shirts are being developed which have their own on-board computer, which will be able to track the pace and acceleration of the wearer.Researchers at the University of Birmingham, UK, who are specialists in “wearable” computers, are exploring ways of remotely monitoring the performance of people playing sports.

This will help to tackle the difficulties in analysing aspects of players’ games such as speed–which can usually only be explored… read more

Google Rolls out Semantic Search Capabilities

March 25, 2009

Google has given its Web search engine an injection of semantic technology to identify associations and concepts related to a query, improving the list of related search terms Google displays along with its results, instead of simply analyzing keywords without understanding their meaning.

“For example, if you search for ‘principles of physics,’ our algorithms understand that ‘angular momentum,’ ‘special relativity,’ ‘big bang’ and ‘quantum mechanic’ are related terms that… read more

How a Tumor Is Like an Embryo

November 7, 2007

The dominant mechanism of cancer metastasis may involve the ability of cancer cells to resurrect early embryonic behavioral programs, which they do through their ability to induce the expression of early embryonic transcription factors.

Automated web-crawler harvests resume info

March 22, 2005

ZoomInfo, a new search engine focused on people, can automatically identify online information on individuals and weave it into detailed summaries.

The Brain in Winter

January 2, 2002

Although some neural functioning is lost from aging, the biggest recent surprise in neuroscience is the discovery of neurogenesis: as the brain ages it creates new neurons.

New robot ‘steered by human thought’: Honda

March 31, 2009

Honda’s latest ASIMO robot version can be steered by human thought, using a helmet-like brain machine interface to perform four basic movements with its arms, legs and tongue.

Breakthrough toward industrial-scale production of nanodevices

November 13, 2007
( National Institute of Standards and Technology)

National Institute of Standards and Technology researchers have developed a new method for growing zinc oxide nanowires in the exact positions where nanodevices for electronic circuits later will be fabricated, in a way that involves a minimum number of fabrication steps and is suitable for industrial-scale applications.
