First clone of champion racehorse revealed

April 18, 2005

The first ever clone of a champion racehorse was cloned from a skin cell of Pieraz, a multiple world champion in equine endurance races.

It’s Moore’s Law, but Another Had the Idea First

April 18, 2005

Computer scientist Douglas Engelbart was the first to conceive the idea that miniaturized circuitry would scale down to vastly smaller sizes than current electronic components.

‘Minority Report’ interface created for US military

April 18, 2005

A computer interface inspired by the futuristic system portrayed in the movie Minority Report could soon help real military personnel deal with information overload.

The system under development at Raytheon lets users don a pair of reflective gloves and manipulate images projected on a panoramic screen. A mounted camera keeps track of hand movements and a computer interprets gestures.

Raytheon plans to offer the technology as a way… read more

The impact of its environment on a quantum computer

April 15, 2005

Scientists have discovered how the performance of a quantum computer can be affected by its surrounding environment.

The study, published in the latest issue of the journal Science, will help engineers to better understand how to integrate quantum components into a standard office computer – moving us one step closer to a future of quantum computing.

Smart plastics change shape with light

April 15, 2005

MIT and German researchers have created the first plastics that can be deformed and temporarily fixed in a second, new shape by illumination with light having certain wavelengths.

These programmed materials will only switch back to their original shape when exposed to light of specific different wavelengths.

DNA project to trace human steps

April 14, 2005

The Genographic Project will collect DNA samples from over 100,000 people worldwide to help piece together to trace ancient migratory routes.

Members of the public will be able to buy a kit that contains all the material needed to add their genetic information to the database.

Laser beams sort stem cells by springiness

April 13, 2005

Measuring the elasticity of cells using a new laser technique promises to pinpoint human stem cells in blood and distinguish cancerous cells from benign ones, say researchers.

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.

Scientists identify protein that controls cancer cells

April 13, 2005

Scientists at Wake Forest University School of Medicine have identified a protein that seems to control the malignant features of brain tumor cells, suggesting a new treatment target for anti-cancer drugs.

They discovered that a little-known protein – called Fra-1 – is present at large amounts in the tumor cells.

Fra-1 is a transcription factor. It is one of many proteins that “read” the genetic material in cells.… read more

An Off-and-On Switch for Controlling Animals?

April 12, 2005

The recent discovery by Yale researchers that they can make fruit flies walk, leap or fly — by shining a laser at the genetically modified insects — may provide clues about a range of disorders, from Parkinson’s disease to drug addiction.

Look out for giant triangles in space

April 12, 2005

The search for extraterrestrial intelligence (SETI) should look for giant structures placed in orbit around nearby stars by alien civilizations, says Luc Arnold of the Observatory of Haute-Provence in France.

And he believes that the generation of space-based telescopes now being designed will be able to spot them.

To ensure the signal is unambiguous, an alien civilization would have to launch a number of objects into orbit around… read more

Gigabit networks should be national priority, says IEEE committee

April 12, 2005

The United States should deploy widespread wired and wireless gigabit networks as a national priority, according to a white paper from the IEEE-USA Committee on Communications and Information Policy (CCIP).

“Providing Ubiquitous Gigabit Networks in the United States,” issued 14 March, says that our nation must act promptly to ensure that a new generation of broadband networks – of gigabit per second speed – is ubiquitous and available to… read more

Molecular breakthrough for plastic electronics

April 12, 2005

Northwestern University chemists have designed organic molecules that self-assemble into an ultra-thin layer (less than six nanometers thick) for use in the dielectric, or nonconducting, component of a transistor.

Their tailored molecular components reduce both operating voltage and power consumption in organic thin-film transistor (OTFT) structures, making low-power consumption OTFTs a reality.

“This means having plastic electronics the size of a pen battery — rather than an automobile… read more

Hang in There: The 25-Year Wait for Immortality

April 12, 2005

“I think it’s reasonable to suppose that one could oscillate between being biologically 20 and biologically 25 indefinitely,” says Cambridge University researcher Aubrey de Grey.
