Tunneling Electrons Do Math

August 3, 2007

Using a novel computing paradigm involving counting single electrons, Delft University of Technology computer engineers have designed nano-sized circuitry that allows tunneling electrons to perform mathematical division calculations.

Seagate Ships 400-GB Drive

November 18, 2004

Setting a new record, Seagate Technology began shipping its first 400-Gbyte drive, the Barracuda 7200.8, this week.

Central dogma of genetics maybe not so central

November 9, 2010

RNA molecules aren’t always faithful reproductions of the genetic instructions contained within DNA, a new study by University of Pennsylvania Medical School shows. The finding seems to violate a central dogma of genetics: DNA letters encode information and RNA is made in DNA’s likeness; the RNA then serves as a template to build proteins.

They found that RNA molecules contained misspellings at 20,000 different places in the genome, with… read more

Retinal Displays Add Data Layer

April 26, 2001

Computer displays that project images directly onto the viewer’s retina, Terminator-style, are expected to be available this fall.

Microvision Inc., based in Bothell, Wash., plans to market Nomad, a single-color version of that kind of display. A tiny laser projector inside a head-mounted display beams light through the pupil and onto the nerve cells in the retina at 800 x 600 pixels resolution.

Uses include data for surgeons… read more

Implant Makes Cells Kill Cancer

January 28, 2009

Harvard University researchers have developed a simple way to achieve immunotherapy inside the body: a polymer implant attracts and trains immune-system cells to go after cancer.

Immunotherapy is a new approach to cancer treatment that could spare patients some of the grueling battery of chemotherapy treatments by retraining the cells of the immune system to recognize and destroy tumors. However, the usual methods for cancer immunotherapy are complex and… read more

Top 3 Robots Coming Soon to the Battlefield: Live @ DARPATech

August 13, 2007

Future military robots were shown at DARPATech 2007, including backpack-able Navy UAVs, an Army hover machine, and Big Dog, a four-legged robotic jogger from Boston Dynamics.

Human eggs divide without sperm

December 3, 2004

Researchers have developed a method to make human eggs divide as if they have been fertilized, creating a potential source of embryonic stem cells that sidesteps ethical objections to existing techniques.

The University of Wales researchers made the eggs devide by injecting phospholipase C-zeta (PLC-zeta), an enzyme produced by sperm. The eggs divided for four or five days until they reached 50 to 100 cells — the blastocyst stage.… read more

A Minority Report interface for the rest of us

November 17, 2010

Toscanini's on-screen interface

Toscanini, free software that runs on Texas Instruments’ “Wireless Watch Development Tool” — an accelerometer-equipped, programmable sports watch that costs $50 — provides a bridge between your movements and digital instruments like synthesizers and keyboards, or anything else you can control from your computer through a MIDI connection.

Project JXTA

May 16, 2001

Sun’s new Project JXTA, using P2P networking, could benefit the AI community by combining the processing power of thousands of networked personal computers to create worldwide virtual supercomputers.

Headed by Bill Joy, Project JXTA (juxtapose) encourages “open source” development, with executable and source code for the initial implementation available in Java and C.

SKorea to build top-speed information highway

February 3, 2009

South Korea will install a nationwide 1 Gbps super-broadband infrastructure by 2013 that would enable downloading a feature film in one to two seconds, according to the state-run National Information Society Agency.

Ten-Minute Cancer Test

August 21, 2007

Researchers at the University of Texas are developing a microfluidics device that detects oral-cancer cells in 10 minutes and is simple and cheap enough for use in the dentist’s office.

The device could be adapted to test for other cancers, including cervical cancer.

The device, made of acrylic, has a small reaction chamber fed and cleaned via tiny inlet and outlet channels. A solution of scrapings from a… read more

Wow! That’s fast TCP!

December 14, 2004

Data has been sent across a wide-area optical network at 101Gbit/sec., the fastest-ever sustained data transmission speed, equivalent to downloading three full DVD movies per second, or transmitting all of the content of the Library of
Congress in 15 minutes.

It was demonstrated by a High Energy Physics research team that included the California Institute of Technology, Stanford Linear Accelerator Center (SLAC) and the Fermi National Accelerator Laboratories (FNAL).… read more

AI game programming book articles solicited

June 1, 2001

Charles River Media is launching the “AI Game Programming Wisdom” book series. The book publisher of Game Programming Gems 1 & 2 is soliciting articles for the first book in the series, covering topics such as designing agent personalities, expert systems, genetic algorithms, and fuzzy state machines. Article proposals are due June 15.

Mutant worms raise hopes for stroke treatment

February 9, 2009

A single gene mutation allows worms to survive at oxygen levels low enough to kill their normal relatives, Washington University School of Medicine researchers have found, suggesting possible new ways to prevent cells being damaged when a stroke or heart attack interrupts their oxygen supply.

Carbon nanotubes’ electronic properties optimized for future applications

August 29, 2007

University of Notre Dame researchers have demonstrated nanotubes’ ability to capture and store one electron per 32 carbon atoms in a single-wall carbon nanotube.

The stored electrons can be readily discharged on demand with the addition of an electron-accepting dye, significantly increasing the photocurrent and photoconductivity of electrical systems.

The results should improve the miniaturization of storage batteries.
