HP Unveils New Interface For Nano-Electronic Circuits

June 10, 2005

According to HP, coding theory will be the key to building a “defect tolerant interface” for its nanoelectronic cross-bar architecture in future processors.

The method adds 50 percent more nanowires as an “insurance policy” to fabricate nano-electronic circuits with nearly perfect yields even though the probability of broken components will be high.

Nanowires show promise for atomic engines

June 9, 2005

Atomic electromagnets made from coils of individual gold atoms could prove valuable for nanocircuits and machines.

Toshiba Readies Write-Once HD-DVDs

June 9, 2005

Volume production of a write-once HD-DVD-R disc that can store 15GB of data will begin in the first half of next year, about the same time that HD-DVD recorders and PC drives will become available.

The write-once discs are expected to offer a cheaper alternative to HD-DVD-RW rewritable discs for customers who buy HD-DVD equipment.

The replicator: create your own body double

June 9, 2005

Two computer scientists are trying to build an intelligent material that can replicate a physical 3-D facsimile of you from nothing more than a stream of video images.

If it works, all you’ll need to project yourself around the globe is an Internet connection and a pile of their “claytronics” self-organizing nanocomputers that can stick to each other and communicate with built-in wireless at the other end to assemble… read more

New suspect implicated in the development of cancer

June 9, 2005

“MicroRNA” molecules – which differ from ordinary messenger RNA in not carrying information for making proteins – are emerging as key gene switches regulating embryo development and cell replication. Now, new evidence shows mis-regulation of microRNAs might trigger development of cancers.

The machine that can copy anything

June 6, 2005

The RepRap, a revolutionary machine that can copy itself and manufacture everyday objects quickly and cheaply, could transform industry in the developing world.

The machine could build items ranging in size from a few millimeters to around 30 centimeters, such as plates, dishes, combs and musical instruments.

The design of the RepRap will be available online and free to use.

See virtual worlds in the round

June 6, 2005

A goldfish bowl in which real-time 3D video images appear suspended in mid-air has been developed by Actuality Systems.

It will be used to visualize slices of the Earth’s crust from seismic data, human organs from MRI and CT scans, and squadrons of aircraft from radar data.

Mission to build a simulated brain begins

June 6, 2005

The “Blue Brain” project, an effort to create the first computer simulation of the entire human brain, right down to the molecular level, has been launched by IBM and the Brain and Mind Institute at the Ecole Polytecnique Federale de Lausanne (EPFL), Switzerland.

Calling on a database of the neural architecture of the neocortex, they will map and model the behavior of neocortical columns.

In the second phase,… read more

Scientists Develop Next-Generation Memory Chip

June 3, 2005

A team of international scientists has developed next-generation memory technology that is theoretically capable of makng a 10-nanometer-thick semiconductor.

Can Tamiflu save us from bird flu?

June 3, 2005

Amid ominous signs that H5N1 bird flu is acquiring the ability to spread more readily among people, many health authorities are pinning their hopes on Tamiflu, but supplies are limited.

TV’s Future Is Here, but It Needs Work

June 2, 2005

What if you had a TiVo-like set-top box, complete with a hard drive that could hold 200 hours of video – but instead of recording live broadcasts, you could tap into an enormous library of shows, stored on the Internet, and watch them whenever you liked?

Camera sees behind objects

June 2, 2005

Researchers from Stanford University and Cornell University have put together a projector-camera system that can read a playing card that is facing away from the camera.

The dual-photography system gains information from a subject by analyzing the way projected patterns of light bounce off it.

Survey: U.S. residents addicted to e-mail

June 2, 2005

U.S. residents are so hooked on e-mail that some check for messages in the bathroom, in church and while driving, a new survey sponsored by America Online Inc. has found.

About a fourth of respondents acknowledged being so addicted to e-mail that they can’t go more than two or three days without checking for messages. That includes vacations, during which 60% of respondents admitted logging into their in-boxes.

Yahoo Meets Searchers’ Mindsets

June 2, 2005

Yahoo has developed a smart search tool, Mindset, that adjusts results based on how commercial they are.

When people search using Mindset, a simple slider appears on top of the search results. As the slider is moved closer to shopping, commercial listings rise to the top. If it’s moved in the other direction, toward researching, the results weigh toward educational, community and informational sites.

Molecular transistor developed

June 2, 2005

University of Alberta scientists have designed and tested a new concept for a single molecule transistor.

They have shown, for the first time, that a single charged atom on a silicon surface can regulate the conductivity of a nearby molecule at room temperature, while all surrounding atoms remain neutral.

A molecule placed adjacent to that charged site is “tuned,” which allows electrical current to flow through the molecule… read more
