Molecules form new state of matter

November 14, 2003

Researchers have coaxed a group of molecules into a Bose-Einstein condensate. The achievement gives physicists a powerful new tool for investigating phenomena such as superconductivity.

Formerly, only atoms could form Bose-Einstein condensates, which are superconducting and superfluid.

New memory device could allow 1 GB per cc storage

November 13, 2003

Engineers at Princeton University and Hewlett-Packard have invented a combination of materials that could lead to cheap and super-compact electronic memory devices for archiving digital images or other data.

The memory device combines low-cost conductive polymer plastic coating with very-thin-film, silicon-based electronics. It could theoretically store more than one gigabyte per cubic centimeter and could result in a single-use memory card that permanently stores data and is faster and… read more

Smile, Gamers: You’re in the Picture

November 13, 2003

Sony Computer Entertainment America has released EyeToy, a miniature camera that attaches to the PlayStation 2 and translates body movements into actions in a video game.

Single speaker unit creates surround sound

November 13, 2003

A home theatre system that produces surround sound using a single speaker unit has been unveiled.

Nirotek’s DVD player, the NIRO 1.1 PRO, achieves the same effect with five individual speakers packed horizontally into a single case. To achieve the surround sound effect, an on-board computer manipulates the signal to each speaker using head related transfer functions that mimic the effects used by the brain to identify the direction… read more

Kasparov ‘forced’ to draw with X3D Fritz

November 13, 2003

Chess legend Garry Kasparov was forced to draw with computer program X3D Fritz on Tuesday in the first game of four.

The match was played on a virtual 3D chess board and Kasparov had to speak his moves through voice recognition software. Kasparov, commentators and the audience all wore 3D glasses so they could see the chess pieces and board “floating” in front of the screen — a move… read more

Where is the real Matrix?

November 12, 2003

Neuroprostheses — human-computer interfaces that connect directly to the human brain, spinal cord or nerves as in The Matrix — are already a reality. But misguided federal policies are keeping them from the people who need them.

The development of microelectrode arrays has allowed researchers in the field to start thinking seriously about a variety of next-generation neuroprosthetic devices, including new types of neuroprostheses. These include vision prostheses for… read more

UK moves to ban human sex selection

November 12, 2003

Britain’s fertility regulator tells the government parents should not be able to choose the sex of their children, based on potential health dangers of selecting sperm by the available methods and for social reasons.

Defense research agency seeks to create supersoldiers

November 12, 2003

Maybe humans themselves need an upgrade, say DARPA thinkers. “The human is becoming the weakest link,” DARPA warned last year in an unclassified report. “Sustaining and augmenting human performance will have significant impact on Defense missions and systems.”

A review of the agency’s latest budget request reveals a host of projects aimed squarely at making soldiers smarter, tougher, faster, and stronger — zin short, superhuman.

Memories in the Corner of My Eye

November 12, 2003

Glasses with a tiny television screen embedded into one of the lenses and hooked up to a PDA are being used to project 1/180-of-a-second subliminal reminders to wearers.

Researcher studies human brain with digital orangutan

November 11, 2003

A robot baby orangutan named Lucy may someday tell us about how the cerebral cortex works and help people develop and build new computational architectures inspired by biological systems, according to Steve Grand, Lucy’s creator and author of Growing Up With Lucy: How to Build an Android in Twenty Easy Steps (Weidenfeld & Nicolson), due out in January.

The New World of Tailored Treatments

November 11, 2003

Pharmacogenomics, or “personalized medicine,” which involves using genomic knowledge to tailor treatments that best suit the individual patient’s needs, could significantly improve treatments for cancer and other major killers.

Could We Live Forever?

November 11, 2003

By mid-century, some countries may have life expectancies approaching 100 and life expectancies might approach 130 by 2050, predicts Dr. James Vaupel, director of the laboratory of survival and longevity at the Max Planck Institute for Demographic Research.

“There is no fixed life span…. From 1840 until today, the life expectancy in the countries that are doing the best has increased two and a half years per decade.… read more

Can Robots Become Conscious?

November 11, 2003

What is consciousness? Can you put it in a machine? And if you did, how could you ever know for sure?

With the continuing gains in computing power, many believe that artificial intelligence will be attainable within a few decades.

Dr. Hans Moravec, a professor of robotics at Carnegie Mellon University in Pittsburgh, believes a human being is nothing more than a fancy machine, and that as technology… read more

Science Times 25th Anniversary

November 11, 2003

To celebrate its 25th anniversary, the New York Times Science News section poses 25 of the most provocative questions facing science.

How Does the Brain Work?

November 11, 2003

While lacking a coherent framework, scientists are making progress in mapping the correlations between brain activity and behavior.

New imaging tools reveal circuits and overall patterns of activity as people solve problems or reflect on their feelings. Genes expressed in mouse brain cells are being mapped so that researchers can begin to find out if neurons that look alike have different proteins and functions. A magnetic device can knock… read more
