Study Details How U.S. Could Cut 28% of Greenhouse Gases

November 30, 2007

The United States could shave as much as 28 percent off the amount of greenhouse gases it emits at fairly modest cost and with only small technology innovations, according to a new report from McKinsey & Company.

The innovations include changes in the lighting, heating and cooling of buildings, for example, that would reduce carbon dioxide emissions from the burning of fossil fuels even as they save money.

‘All-optical’ switch could advance light-based telecommunications

April 29, 2005

Duke University physicists have developed a switching technique that uses a very weak laser beam to control a much stronger beam. The achievement could make optical telecommunications devices perform far more efficiently.

The report in Science also suggests possible techniques for using switching beams as weak as single photons, making them useful for quantum computing.

Nanotube separation method promises to advance imaging, catalysis, and fuel cells

February 24, 2011

Dispersion of single-walled carbon nanotubes (Chemical Communications)

A lab at Rice University has developed an efficient method to disperse nanotubes in a way that allows inorganic metal complexes with different functionalities to remain in close contact with single-walled carbon nanotubes while keeping them separated in a solution.

That separation is critical to manufacturers who want to spin fiber from nanotubes, or mix them into composite materials for strength or to take advantage of their electrical properties.… read more

Online Virtual World Revs Up

March 20, 2002

It’s ten past 6 and you’re late. The two full moons are already peeking above the horizon, drenching the marbled purple landscape in an amber twilight.

The Crystal Pyramid Theater, that you architected and built last week, is just in sight now as you glide over lollipop trees. Above a field of giant cotton balls you glance up at your holographic watch.

(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.

A recipe for making strings in the lab

May 16, 2005

Theoretical physicists in the Netherlands have proposed a way to make superstrings in the laboratory: by trapping an ultracold cloud of fermionic atoms along the core of a quantized vortex in a Bose-Einstein condensate.

Hopefully this will allow observation of the supersymmetry between bosons and fermions, thus providing the first experimental evidence to support superstring theory.

Supercomputer smashes world speed record

April 18, 2002

A Japanese supercomputer has recorded the world’s fastest floating point calculation speed at 35.61 teraflops — five times faster than IBM’s ASCI White’s 7.23 teraflops.
The supercomputer is installed in The Earth Simulator at the Marine Science and Technology Center in Kanagawa. It which simulates climate change using data collected by Earth-monitoring satellites.

According to an NEC spokesman, the supercomputer was tested using the Linpack benchmarking software.… 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

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

Rest in Peace, RSS

“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….

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.
