Researchers create world’s fastest transistor

November 10, 2003

Researchers at the University of Illinois at Urbana-Champaign have created the world’s fastest transistor, with a frequency of 509 gigahertz.

It could find use in applications such as high-speed communications products, consumer electronics and electronic combat systems.

Unlike traditional transistors, which are built from silicon and germanium, the Illinois transistors are made from indium phosphide and indium gallium arsenide, which are faster and can support a much higher… read more

Library Wants to Put Chips in Books

November 7, 2003

The Electronic Frontier Foundation is concerned about the San Francisco Public Library’s plans to track the 2 million books, CDs and audiovisual materials by inserting RFID chips.

The End of the Oil Industry

November 7, 2003

Advances in technology are allowing the developed world to diversify supplies of energy and reduce their demand for petroleum, thus loosening the grip of oil and the countries that produce it.

Electronic Memory Research that Dwarfs the Silicon Chip

November 7, 2003

Researchers have constructed an electronic memory circuit from disordered arrays of electronic clumps of gold atoms.

A Link To Longevity: Cholesterol-bearing Molecules

November 7, 2003

Centenarians tend to have larger than average cholesterol-carrying molecules, says a new study. It adds to evidence suggesting that the size of lipoproteins, both good and bad, may play a significant role in heart disease and diabetes and thus longevity. It also found that subjects with cardiovascular problems were less likely to have large lipoproteins.

Study Suggests Life Sprang from Clay

November 7, 2003

Howard Hughes Medical Institute and Massachusetts General Hospital researchers say materials in clay are key to some of the initial processes in forming life. A clay mixture called montmorillonite helps form little bags of fat and liquid and helps cells use RNA.

Approval sought to test brain implant

November 7, 2003

Cyberkinetics Inc. is about to ask federal regulators for permission to start testing its BrainGate device, which would enable paralyzed people to control computers directly with their brains or possibly help them move their limbs.

A surreal timeline: When is ‘The Matrix’?

November 7, 2003

The Associated Press has compiled an estimated timeline of the war between men and machines.

2010-60 — Humans create humanoid drone robots with Artificial Intelligence to fill jobs as construction laborers and servants.

2075 — AI programs evolve and some robots began to resent their human overlords.

….

“This timeline is incredibly flawed. It fails to mention the fact that ‘The One’ has been inserted into… read more

Nanowire film brings cheaper, faster electronics a step closer

November 7, 2003

Researchers at Harvard University have demonstrated for the first time that they can easily apply a film of tiny, high-performance silicon nanowires to glass and plastic, a development that could pave the way for the next generation of cheaper, lighter and more powerful consumer electronics.

According to Dr. Charles M. Lieber, head of the research project and a professor of chemistry at Harvard, the first devices made with this… read more

Molecular structures offer insights for nanoscale self-assembly

November 6, 2003

Hollow spherical vesicles formed by large-scale, wheel-shaped inorganic “POM” molecules represent a new kind of self-assembly in nature, with implications for nanoscience.

These vesicles are described in the November 6, 2003 issue of Nature.

Giant wheel-shaped polyoxomolybdate (POM) molecules, composed of hundreds or even thousands of molybdenum and oxygen atoms, possess the advantages of single molecules, such as well-defined structures and uniform size and mass, as well as… read more

Biology gets digital in Maryland

November 6, 2003

Biologists and techies are meeting at the “Digital Biology: the Emerging Paradigm” conference to find out how to integrate the reams of information spewed out from sequencing machines and computer models to achieve useful results.

Finally, the plaque-buster?

November 6, 2003

Apo A-1 Milano, a synthetic form of HDL or “good cholesterol,” appears to reverse years of coronary plaque build-up in a few weeks. It may lead to a long-sought complement to cholesterol-lowering drugs.

Startup Says Quantum Crypto Is Real

November 6, 2003

MagiQ Technologies Inc. announced it’s shipping the first security system based on quantum cryptography.

Kurzweil suggests books on cyberdemocracy on NPR

November 5, 2003

Speaking on NPR’s Talk of the Nation, Ray Kurzweil recommended two books for NPR’s “library of democracy”: Smart Mobs, The Next Social Revolution, Transforming Cultures and Communities in the Age of Instant Access by Howard Rheingold; and The Future of Ideas, The Fate of the Commons in a Connected World by Lawrence Lessig.

The show invited leaders from various fields to suggest books that embody the ideas… read more
