Nanotubes Form Along Atomic Steps

December 22, 2004

Weizmann Institute of Science researchers have developed a new approach to aligning carbon nanotubes by forming the nanotubes on a sapphire wafer surface.

The orientation of nanotubes on these wafers follows the surfaces’ crystal planes at the atomic level. Changing how the sapphire surface is cut would produce different nanowire arrangements.

The research may eventually make it possible to assemble nanowires in ordered arrays for the production of… read more

NASA discovery of arsenic-based bacterium expands scope of SETI research

Evidence that the toxic element arsenic can replace the essential nutrient phosphorus in biomolecules of a naturally occurring bacterium expands the scope of the search for life beyond Earth, according to Arizona State University scientists who are part of a NASA-funded research team reporting findings in the Dec. 2 online Science Express.

It is well established that all known life requires phosphorus, usually in the form of inorganic phosphate.… read more

Space Medicine Gets Smart

June 22, 2001

Smart medical devices that help astronauts handle emergencies such as electrical burns will become part of the International Space Station perhaps as early as next month.

Further down the road, astronauts in trouble may also rely on “virtual clinics” on earth for in-depth medical assistance, which could also be used to help people on the ground in isolated places with no doctor nearby.

If an astronaut were to… read more

Researchers Develop “Brain-Controlled” Wheelchair Robotic Arm

February 12, 2009

University of South Florida researchers have created a wheelchair with a robotic arm and computer interface, both operated by capturing the user’s brain waves and converting them into actions.

Zeno Could Be Next Robot Boy Wonder

September 6, 2007

Hanson Robotics’ latest creation is a 17-inch, 4.5-pound personal robot boy that can walk, talk, express emotions, and make eye contact.

The prototype, which will have a formal unveiling at Wired Nextfest in California next week, is described as an intelligent “conversational robot” and will ultimately be part of Hanson’s “Robokind” line of personal, interactive bots.

“We’re combining the best artificial intelligence with this theater for fiction so… read more

Building a Smarter Search Engine

January 4, 2005

Carnegie Mellon University researchers have developed Clusty, a search engine using AI to search the Web and cluster results by topic.

Clusty searches the results of other search engines and indexes, applies AI to pick out the major themes found within the results for each search, and organizes them into folders.

World’s highest-res display matches human eye’s acuity

A 20-million-pixels screen with the visual acuity of the human eye at 10 feet has been developed at Sandia National Laboratories. It is also the fastest in the world in rendering complex scientific data sets, says program leader Philip Heermann.

The Sandia images are created through massively parallel imaging, using outputs of 64 computers and splitting data into 16 screens arranged as a 4 by 4… read more

High-Definition Video over Wi-Fi

February 19, 2009

Quantenna’s forthcoming Wi-Fi chip set will allow for transmittng a gigabit per second — enough for high-definition video content — using a technique called beam forming.

Printing Nano Building Blocks

September 17, 2007

Researchers from IBM’s Zurich Research Lab have devised a way to print particles as small as 60 nanometers in diameter with single-particle resolution.

The technique lets researchers arrange tiny particles of various materials into well-defined structures on a surface–a step necessary for the mass production of devices such as nanowire transistors, biomedical sensors, and flexible, ultrasmall lenses capable of bending light.

Grids Unleash the Power of Many

January 14, 2005

Computer scientists in three states — West Virginia, North Carolina, and Colorado — are each combining their technology resources into separate computer grids that will give researchers, universities, private companies and citizens access to powerful supercomputers.

The project designers say these information aqueducts will encourage business development, accelerate scientific research, and improve the efficiency of government.

Automated invention machines

August 13, 2001

Genetic programming research has reinvented engineering patents generated as recently as last year, says John Koza, consulting professor of biomedical informatics at Stanford.

Concentrating on what he calls “the black arts” — areas where there’s no known mathematical method to solve the problem quickly — Koza’s recent focuses include controllers, analog circuits and cellular automata.

Koza’s resources include a 1,000-node parallel computing cluster at Genetic Programmingread more

Scientists Model Words as Entangled Quantum States in our Minds

February 26, 2009

Researchers from Queensland University of Technology and the University of South Florida have investigated the quantum nature of word associations and presented a simplified quantum model of a mental lexicon.

They view quantum theory as an abstract framework for developing models of “non-separability” (of which quantum entanglement is a physical manifestation) in a variety of domains including cognition.

This kind of research is an example of an emerging… read more

Scientists get first look at nanotubes inside living animals

September 25, 2007

Rice University scientists have captured the first optical images of carbon nanotubes inside inside living fruit flies, using near-infrared fluorescent imaging.

Based on their assays, the team estimates that only about one in 100 million nanotubes passed through the gut wall and became incorporated into the flies’ organs.

Samsung Boasts Fastest Ever Multimedia RAM

January 25, 2005

Samsung Electronics has today begun mass production of what it claims is the world’s fastest RAM for multimedia applications.

Samsung’s 256Mb XDR (eXtreme Data Rate) DRAM is 10 times faster than DDR 400 memory and five times faster than RDRam (PC800), Samsung claims.

Samsung plans to introduce a 512Mb XDR DRAM, capable of transferring data as fast as 12.8Gbps, during the first half of this year.

Is Skype About to Release Video Calling for Mobile Devices?

December 27, 2010

Skype, a provider of voice and video calling services over the Internet, might be poised to release video calling for mobile devices equipped with a front-facing camera and running Skype at the Consumer Electronics Show next year, according to a number of reports.
