People with life-threatening allergies to peanuts might be able to rest easy at their friendly neighborhood Thai restaurants soon, if research announced this week proves true.

A release from North Carolina Agricultural and Technical State University says researcher Mohamed Ahmedna has developed whole, roasted peanuts in which the allergen is completely inactivated and that serum from people with severe peanut allergies did not react to the processed peanuts at all. The university paper does not explain the process at all. However, it claims the technique inactivates peanut allergens without degrading the taste or quality of treated peanuts.

Researchers at Intel this week are showing off an silicon modulator that can pass 40 gigabits of data in a second, a new record that indicates that fiber-inside-computers is really coming.

A modulator is an component from the fiber optic industry. It essentially chops up light from a laser into blips that ultimately will be understood as 1s and 0s by a computer. Right now, computers (and chips) pass signals via electrons traveling along metal wires. Metal wires give off heat, which has created an energy crisis inside computer.

By contrast, fiber optics transmit data with photons, which are faster … Read more

Paul Horn, the director of IBM Research for the past 11 years, is stepping aside to take an academic scientist position at New York University. He will be replaced by John Kelly, IBM's senior vice president of technology and intellectual property.

Horn's tenure at IBM Research is marked by technology accomplishments--including when IBM's Deep Blue computer beat former chess champion Garry Kasparov--and a sharper commercial orientation of IBM's vaunted labs.

During his time there, Horn, 60, sought to connect IBM researchers with customers and partners. As IBM began making a growing portion of its revenue from … Read more

Although you can't singlehandedly fix the woes of national health care that are spotlighted in the movie Sicko, many free Web sites at least put a bit more power in your hands to manage personal wellness or a medical crisis. Just share your data wisely.

WebMD (a Webware 100 winner) offers videos, virtual support groups, quizzes, blogs, doctor lookups, and a spiffy symptom checker. Look up drugs by a pill's color, imprint or shape. WebMD won't spam you, but as with its competitors, if you subscribe to e-mail updates about some unappetizing ailment, then prepare for related … Read more

Last week, Opti Technologies announced a patent infringement lawsuit against a bevy of chip companies: Advanced Micro Devices, Atmel, Broadcom, Renesas Technology, Silicon Storage Technology, SMSC, STMicroelectronics and Via Technologies. At issue are two patents for "Compact ISA-Bus" technology.

Opti had recently sued Apple and AMD over three patents for "Predictive Snooping" technology used in some computer chips. And, in August of last year, Opti settled with Nvidia for $11 million plus up to $9 million more if nVidia continues to use Opti's technology in its products. The nVidia action included all five of the above-mentioned patents.

Silicon Valley faithful will remember Opti as a once-respected chip company that fell on hard times. Is the company's recent patent litigation rampage the death-throws of a desperate company or a promising new business model? Let's go through it.

At present, Opti has but one full-time employee, CEO Bernard Marren. And, according to the company's 1995 proxy statement, Marren gets a cut of everything he brings in to shareholders on a sliding scale that starts at 5 percent and ramps down to 1 percent. Mike Mazzoni, the company's part-time CFO, appears to have the same deal.

Do the math; it's not bad work if you can get it.

I had lunch with Marren a few weeks ago. The 71-year-old industry veteran seemed excited about Opti's prospects and he may have reason to be. Marren isn't new to executive management. He's a former founder and president of electronic distributor Western Micro Technology and the Semiconductor Industry Association (SIA). He sits on a number of boards, including Microtune, Infocus and Unipixel. Marren knows his way around the negotiating table.

For better or worse, patent infringement litigation is business as usual in the chip industry. If not for broad cross-license agreements, chip companies might spend more time suing each other than developing products. Nevertheless, some companies have carved out significant niches by developing and licensing technology. ARM, Qualcomm, Rambus, Tessera, even IBM and Texas Instruments, make a solid business of it. But, for the most part, these companies develop technology with that business model in mind. Believe me, they prefer to negotiate than to litigate.… Read more

Hydrogen is lightweight and efficient as a fuel. When it burns, you get water as the exhaust, and the fuel cell technology that burns the gas is well developed. The major hang-up has been how to produce hydrogen without needing lots of fossil-derived energy.

Apparently, the way to cheap hydrogen is through aluminum. Purdue researchers earlier this year announced they'd found a way to use aluminum to get hydrogen from water. Today a Chinese ceramicist who did graduate work in Portugal says there's an even simpler way to derive hydrogen. This process uses powdered aluminum at room temperature, … Read more

American coal experts want more information. And they want the U.S. government to pay for it. Today the National Research Council issued a call for more federal money to find and assess America's coal deposits.

Currently over half of the U.S. electricity is generated by burning coal. But there is uncertainty about future use and availability of coal. And there is the issue of CO2 emissions and other pollution from coal-burning power plants. Plus the U.S. must now compete with China and other nations for use of the world's coal.

In short, says the Council'… Read more

It's taken 27 years to reach 1 billion PCs in use, and market researchers say it will take only five to reach the next billion.

Forrester Research is set to release a report Monday titled, "Worldwide PC Adoption Forecast to 2015," saying that many of those next billion will be used by first-time PC users in emerging nations like Brazil, Russia, India and China. At least 775 million new PCs will be in use in those countries by 2015, according to Forrester.

Not only is access to computers beneficial to those users, it also will represent a … Read more

Researchers at the University of Illinois got a bright idea. They developed a form of lighting that's more efficient than standard incandescent bulbs. And it's lighter and thinner than current fluorescent lights, which require a ballast and glass tubes. The diagram above shows how the researchers' aluminum foil-based "microcavity" plasma system works to produce light.

The researchers say their lighting system would look like a luminous, flat screen that could hang on walls in residential and commercial locations. The technology would even allow for curved and flexible versions of the lights, which could fit a wide … Read more
