Panel Sees No Unique Risk From Genetic Engineering

July 28, 2004

Genetically engineered crops do not pose health risks that cannot also arise from crops created by other techniques, including conventional breeding, the National Academy of Sciences said in a report issued yesterday.

The report suggests that in some cases, surveillance might be needed after a food gets to the market to check for possible health effects, something not done now. It also calls for some information on the composition… read more

Craig Venter’s Epic Voyage to Redefine the Origin of the Species

July 28, 2004

He wanted to play God, so he cracked the human genome. Now he wants to play Darwin and collect the DNA of everything on the planet.

3D audio system developed by MP3 pioneer

July 28, 2004

A sound system that creates immersive, three-dimensional audio for everyone in a room has been developed by one of the creators of the MP3 audio format.

It uses a principle known as “wave field synthesis” to create complex audio illusions for everyone within a defined space. Computers are used to predict the way multiple sound waves will interact with each other within a space. Then, a multitude of small… read more

Navy Hires IBM To Build Military’s Fastest Computer

July 28, 2004

IBM has won a contract to build the U.S. military’s fastest supercomputer. It will run at 20 teraflops–about three times faster than any current system in use by the Department of Defense.

It will improve weather forecasting, missile design, and oceanographic-mapping capabilities. The system is scheduled to begin operating by September.

Amplified Intelligence

July 28, 2004

Will machines make humans smarter or just more dependent on our calculators, car navigators, and kitchen conveniences? Dr. Ken Ford of the Institute of Human and Machine Cognition reclassifies several key problems in developing smarter machines into a category called “Amplified Intelligence.”

His Institute for the Interdisciplinary Study of Human & Machine Cognition is involved in “building cognitive prostheses, computational systems that leverage and extend human intellectual capacities, just… read more

Transplant hope for stroke sufferers

July 27, 2004

Transplants of human fetal stem-cells may help repair stroke-induced brain damage.

Fetal stem cells have advantages over adult and embryonic alternatives. Adult stem cells do exist in the brain, but they are difficult to obtain, survive less well after transplantation and may be less versatile than their younger counterparts.

Another approach would be to add a gene to the stem cells that boosts growth and prevents the formation… read more

Handheld Computer-Phone Is Here

July 27, 2004

T-Mobile USA and Hewlett-Packard will introduce the first-ever handheld computer that also works as a cell phone and can tap into the Internet using high-speed wireless hot spots next month.

Toshiba plans high-res DVD format

July 27, 2004

Toshiba and its partners yesterday raised the tempo in the battle to determine the next-generation DVD format, saying they were on track to launch next year a DVD recorder capable of storing more than eight hours of high-resolution content on one disc (around 27GB for single-layer and 54GB for dual-layer discs).

Microsoft’s Japanese unit, meanwhile, said the company’s next Windows-based operating system, called Longhorn, would be compatible with HD-DVD.… read more

Endangered species’ DNA stored on ‘Ark’

July 27, 2004

Britain’s “Frozen Ark” project hopes to collect frozen DNA and tissue specimens from thousands of endangered species.

Like Noah, the scientists harbor hopes of repopulating the Earth.

With about 10,000 species listed as in danger of extinction, the ark will fill quickly.

Infineon’s fashion alliance produces multimedia jacket

July 27, 2004

Infineon Technologies AG and German clothing manufacturer rosner GmbH & Co. have jointly developed a men’s jacket, known as mp3blue, that contains built-in mobile telephony via Bluetooth and an MP3 player. A textile keyboard on the sleeve controls the electronic features.

When the wearer of the jacket places a telephone call, the stereo system becomes a headset and the music is automatically interrupted when calls come in.

Motorola rolls out Wi-Fi phone

July 27, 2004

Motorola has introduced a new phone that it says will switch calls seamlessly between cellular services and wireless WiFi Internet networks, potentially offering big savings for customers.

It is planned to be commercially available by fall or early 2005,

The Internet Meets the Neural Net

July 26, 2004

New technlogies for interfacing brain and computer include low-cost EEG, optical signals, and direct neural interfacing.

Faster, cheaper, better

July 26, 2004

The ability to build powerful computers cheaply, combined with growing commercial demand for high-end computing power, is creating a renaissance in the field of supercomputing.

ET first contact ‘within 20 years’

July 26, 2004

If intelligent life exists elsewhere in our galaxy, advances in computer processing power and radio telescope technology will ensure we detect their transmissions within two decades, says SETI Institute senior astronomer Seth Shostak.

He based his prediction on the Drake formula for the likelihood of alien civilizations existing, combined with estimates of the time necessary for this observational task, based on the capabilities of planned radio telescopes.

Shostak… read more

When Technology Imitates Art

July 23, 2004

With the aid of scanners and software, computer-guided milling machines can precisely duplicate sculptures and other art objects, blurring the line between what is authentic and what is not.
