’2001: HAL’s Legacy’ to air on PBS Nov. 27 (reminder)

November 27, 2001

Arthur C. Clarke, Ray Kurzweil, and other leading scholars in artificial intelligence and computer science will be featured in the forthcoming television documentary “2001: HAL’s Legacy,” to air nationwide on PBS stations starting Tuesday, November 27, according to Dr. David G. Stork, creator of the documentary.

The experts reflect upon the state of the art, how far we’ve come, and how far we have yet to go… read more

Fluorescent puppy is world’s first transgenic dog

April 24, 2009
(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

Fruit flies could hold key to future internet

March 25, 2011

Researchers at Carnegie Mellon have developed an algorithm for determining optimal communications paths in digital environments such as multiprocessor arrays by studying fruit flies, says Dr. Ziv Bar-Joseph.

Network applications rely on organizing nodes to determine routing and how to control processors. One method uses a Maximal Independent Set (MIS), a technique that identifies a subset of computers that together connect to every other node in the network and… read more

Nanotechnology’s progress and challenges addressed during ACS meeting

March 18, 2005

More than 60 presentations, in symposia ranging from medicine to the environment to business, highlight nanotechnology’s progress and challenges during the 229th national meeting of the American Chemical Society in San Diego, March 13-17.

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.

Drexler Warns Terror Symposium: Nanotech Has ‘Extreme Downsides’

December 19, 2001

The scientist who coined the term nanotechnology warned Tuesday that development of “extremely powerful, extremely dangerous technologies” must be shepherded by stewards tutored in both its promise and its peril.
“One of my profound hopes is that the new spirit of seriousness about life and death issues that we see in the wake of Sept. 11…will encourage people to pay a little less attention to politics and a little more… 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.

Physicists set new record: register with 14 quantum bits

April 4, 2011

Qbits Register

Physicists at the University of Innsbruck in Austria have achieved controlled entanglement of 14 quantum bits (qubits), realizing the largest quantum register ever produced.

The scientists have almost doubled the record for the number of entangled quantum bits realized experimentally. They confined 14 calcium atoms in an ion trap (similar to a quantum computer), and then manipulated them with laser light. The internal states of… read more

Biolaser Lights Up Stem Cells

April 1, 2005

Scientists have developed a laser that could illuminate stem cells in greater detail than ever, revealing the important steps they take to become neuron, heart or other types of cells.

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

‘Nanocircles’ act as Trojan horse to shut down disease-causing genes, study finds

January 28, 2002

Stanford scientists have synthesized a molecule of DNA that is capable of shutting off specific genes in living bacteria. Dubbed the “nanocircle,” the new nanometer-size molecule might one day give researchers the ability to target harmful genes that cause cancer and other diseases in humans.
The technique — known as “rolling circle amplification” — is now one of the hottest fields in biotechnology because it offers the potential to produce… read more

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….

Political views are reflected in brain structure

April 8, 2011

Differences in political orientation are tied to differences in the structures of our brains, University College London researchers have found.

Individuals who call themselves liberal tend to have a larger anterior cingulate cortex, while those who call themselves conservative have a larger amygdala, the researchers say. This is consistent with reports showing a greater ability of liberals to cope with conflicting information and a greater… read more

US rolls out robotic broadband airship

April 13, 2005

US communications company Sanswire plans to deliver line-of-sight wireless broadband and mobile phone signals to an area the size of Texas from a “Stratellite.”
These geostationary, robotic airships, hovering at 65,000 feet above the Earth, will provide the low latency required for realtime birectional communications that is not available with satellites because of their distance.

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.
