Instant stem cells — just add water

December 19, 2003

Researchers are honing a technique to create dried stem cells that can be revived just by adding water. The “instant” cells might provide mobile therapies for remote regions or the battlefield.

Because some stem cells can make fresh bone, muscle or blood, doctors hope to use them to repair tissues. But, like transplant organs kept on ice, their shelf life will be limited without an easy way to store… read more

Sony’s Humanoid Robot Learns How to Jog

December 18, 2003

Sony has demonstrated a walking robot that can smoothly simulate running. The breakthrough required sophisticated features in the robot’s joints and CPU to keep its balance and manage delicate maneuvers.

Seven Days of Creation

December 18, 2003

Advanced Cell Technology is working to clone human embryos and perfect other techniques in pursuit of stem cells. ACT’s ultimate goal: hundreds of stem cell lines to treat everything from Alzheimer’s to diabetes to Parkinson’s.

Body handles nanofiber better

December 18, 2003

Researchers from Purdue University have made a discovery that may hold promise for tissue regeneration: carbon nanofibers are surprisingly compatible with human tissue.

Their experiments showed that increasing the amount of carbon nanofibers in a polycarbonate urethane composite implant increased the functions of nerve and bone-forming cells and decreased the function of scar-tissue formation.

Carbon nanotubes also have strong electrical properties. “These carbon nanofibers also interact with neurons,… read more

PDA translates speech

December 18, 2003

Researchers have put together a two-way speech-to-speech system that translates medical information from Arabic to English and English to Arabic and runs on an iPaq handheld computer.

Optical fibres cut their losses

December 18, 2003

New super-thin optical fibers confine light signals much more securely than their thicker counterparts. The new low-loss design will combat the leaks that can severely weaken a telecommunications signal when conveyed over many kilometers.

The new fibers are 50 nanometers across — around 10,000 times thinner than current optical fibers. They are also highly flexible, so they can guide light signals around tight bends, which will help the production… read more

‘Humanised’ organs can be grown in animals

December 18, 2003

Injecting human stem cells into sheep fetuses produces animals with partially human organs — a possible source of matched transplants.

It would also allow doctors to obtain immune-compatible cells without having to create human embryos by therapeutic cloning.

The idea of using part-human, part-animal chimeras as living factories for producing cells or organs raises a host of ethical and safety issues.

Google tests book search

December 18, 2003

Google has launched Google Print Beta, which lets Web surfers access brief excerpts from books, critic reviews, and bibliographic and author’s notes.

The experiment is similar to Amazon’s “Search Inside the Book,” a searchable index of millions of pages of books.

The Google Print feature works by typing “print.google.com” and any desired term or phrase into the Google search bar.

The Rise of India

December 17, 2003

India’s technological success is challenging the definitions of globalization and Corporate America is becoming concerned. “There’s just no place left to squeeze” costs in the U.S., says Chris Disher, a Booz Allen Hamilton Inc. outsourcing specialist.

“That’s why every CEO is looking at India, and every board is asking about it.” neoIT, a consultant advising U.S. clients on how to set up shop in India, says it has been… read more

Terrorism Lends Urgency to Hunt for a Better Lie Detector

December 17, 2003

A near-infrared light can detect lies as they form in the brain of volunteers. It may replace the often-inaccurate polygraph to detect lies told by spies, saboteurs and terrorists.

E-textiles: The Ultimate in Flexible Computing

December 17, 2003

E-textiles are being developed that can sense tank movements, monitor homes for noxious chemicals, help firefighters maneuver in smoky buildings, and perhaps help stroke victims recover their function.

A Brain Scan Identifies Race Bias

December 17, 2003

Scientists have developed a brain scan that can purportedly identify racists.

The technique was used on white volunteers shown photographs of black individuals. In those with racist tendencies, a surge of activity was seen in part of the brain that controls thoughts and behavior. Scientists believe this reflected volunteers’ attempts to curb their latent racism.

“To my knowledge, this is the first study to use brain imaging data… read more

Red Sea Urchin Almost Immortal

December 17, 2003

The red sea urchin can last for more than 200 years with few signs of age-related disease, researchers have found. This could help scientists uncover the secret of longevity and aging.

Execs beg nanotech funding; paying for better homeland security devices called risky

December 17, 2003

Nanotechnology could strengthen the nation’s shield against terrorist bombs, biological weapons or attacks on power plants and reservoirs, participants at the Nanotechnology and Homeland Security Forum said Monday.

But homeland security may not benefit from nanotechnology’s potential unless government funding lays the groundwork for the private businesses that could produce new defense products, most experts agreed.

Possible nanotech uses could include self-copying nanoparticles that could be spread in… read more

Materials Retain Useful Properties At Nanoscale Researchers Find

December 17, 2003

Ferroelectric materials, used in modern electronics devices, have been discovered to retain their properties when present in extraordinarily tiny amounts. This discovery implies that this and other materials with similar properties may be valuable at nanoscale in the production of small, smart communications devices, tiny diagnostic instruments and nano-robots.
