Industry Says Limits on Moore’s Law Far Off

March 19, 2002

Limits predicted by Moore’s Law won’t be reached until after 2028, according to a semiconductor industry leader.

Calvin Chenming Hu, Taiwan Semiconductor Manufacturing Corporation’s Chief Technologist, said 9 nanometer devices “can be ready more or less on time, in 2028 according to long-term forecasts or 2024, according to the 2002 (industry roadmap).”If Hu’s view is correct, fundamental limits on current two-dimensional integrated circuit technology are still far off.

(Byeong Chun Lee)

A cloned beagle named Ruppy (Ruby Puppy) is the world’s first transgenic dog. She and four other beagles all produce a fluorescent protein that glows red under ultraviolet light.

A Seoul National University team created the dogs by cloning fibroblast cells that express a red fluorescent gene produced by sea anemones.

This new proof-of-principle experiment is intended to open the door for transgenic dog models of… read more

Nanotechnology roadmap published: statement by Eric Drexler

December 7, 2007

EXCLUSIVE TO KURZWEILAI.NET — I’m pleased to report that the Technology Roadmap for Productive Nanosystems has finally been released. This marks the completion of the first broad, multidisciplinary effort to explore how current laboratory techniques for atomically precise fabrication can be extended, step by step, toward increasingly advanced products and capabilities.

The Roadmap project was led by the Battelle Memorial Institute, a not-for-profit corporation that manages a set of U.S.

Human evolution at the crossroads

May 16, 2005

Where are humans headed? Here’s an imprudent assessment of five possible paths, ranging from homogenized humans to alien-looking hybrids bred for interstellar travel.

Let the robot revolution commence

April 18, 2002

“Californian company Evolution Robotics (ERI) plans to release an operating system that it claims will do for robotics what Microsoft did for the personal computer with DOS and Windows.
“The idea has two aims: to slash the time and cost involved in developing new robots, and to let people who buy robotic lawnmowers, beer gophers or vacuum cleaners reprogram them.”

Microsoft, I-Robot, and other competitors are pushing their own… read more

More-Precise Genetic Engineering for Plants

April 30, 2009

New techniques allow for more precise changes in plant genes, greatly increasing the efficiency of generating genetically engineered plants for use as food or fuel, or for absorbing carbon and cleaning the environment.

Glow-in-the-dark cat could help cut disease

December 13, 2007

Scientists have genetically modified three cloned kittens so they appear fluorescent under ultraviolet light, a procedure which could help develop treatments for human genetic diseases.

The Gyeongsang National University (South Korea) scientists cloned the cats after manipulating a gene to change their skin color.

A spokesman for the Ministry of Science and Technology said: “The ability to produce cloned cats with the manipulated genes is significant as it… read more

Rise of the Plagiosphere

May 27, 2005

Emerging technologies are causing a shift in our mental ecology, one that will turn our culture into the plagiosphere: we look at our ideas with less wonder, and with a greater sense that others have already noted what we’re seeing for the first time.

The plagiosphere is arising from three movements: Web indexing, text matching, and paraphrase detection.

Invisible Wi-Fi signals caught on camera

March 10, 2011

WiFi Camera

A team of designers from the Oslo School of Architecture and Design has created a device that can produce a large scale visualization of the fluctuating Wi-Fi signals around a city.

Their latest prototype is a four-meter-tall rod, lined with LEDs that incorporates a microcontroller, Wi-Fi device, computer program, and Wi-Fi module to reveal its signal strength, displayed by lighting up an appropriate number of LEDs.

The signal… read more

Scientists Get Atoms Ready for a Close-Up

May 15, 2002

Scientists at Lucent Technologies’ Bell Labs have developed a microscopy technique that can image individual atoms within a silicon sheet, allowing for precision analysis of dopant distribution.
As transistor sizes shrink, they require higher concentrations of electrons to work and are more sensitive to problems with dopant distribution.

The Lucent microscope shoots a narrow beam of high-energy electrons and measures deflection angles to locate individual atoms.

Rest in Peace, RSS

May 5, 2009

“It’s time to get completely off RSS and switch to Twitter,” advises technology journalist Steve Gillmor.

“Twitter, not RSS, became the early warning system for new content. Facebook, not RSS, became the social Rolodex for events, casual introductions to RSS’ lifeblood, the people behind the feeds. FriendFeed, not RSS, captured the commentsphere. RSS got locked out of its own party….

“The race for realtime is already… read more

Move over, silicon: Advances pave way for powerful carbon-based electronics

December 19, 2007

Princeton engineers have developed a novel way to replace silicon with carbon on large surfaces, clearing the way for new generations of faster, more powerful cell phones, computers and other electronics devices.

The Princeton engineers developed a method to place small graphene crystals on a computer chip, demonstrating the method by making high-performance working graphene transistors.

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.

Consciousness in Human and Robot

June 6, 2002

AI skeptics offer several reasons
why robots could never become
conscious. MITs’ humanoid Cog robot
project may give them pause.

Study establishes major new treatment target in diseased arteries

May 11, 2009

By eliminating the gene for a signaling protein called cyclophilin A (CypA) from a strain of mice, researchers at the University of Rochester and were able to provide complete protection against abdominal aortic aneurysm, a fatal event in 90 percent of cases.

Inhibition of CypA also appears to have benefit in several diseases that involve blood vessels in the brain and heart, the researchers suggest.
