Nano-based RFID tags could replace bar codes

March 19, 2010


Rice University and Sunchon National University researchers have developed an inexpensive, printable transmitter that can be invisibly embedded in plastic or paper packaging, cutting costs of RFID tags dramatically and replacing bar codes.

Instead of expensive silicon-based components, the technology is based on carbon-nanotube-infused ink used for ink-jet printers. The tags are powered by radio waves from the RFID reader.

Keep Searching

July 28, 2008

Cuil, a new search engine, displays long descriptions of each search result alongside images from 120 billion Web pages.

Cuil attempts to see relationships between words and ranks sites by relevance rather than links.

Samsung’s gun-toting robot

December 5, 2006

The Intelligent Surveillance and Security Guard Robot, being developed by Samsung, will guarantee “perfect guarding operation,” in contrast with human guards who are all too prone to succumb to fatigue or inclement weather.

It has two cameras–one for daytime watch and another, infrared one for the night–and a laser rangefinder.

Congress considers paywalling science you already paid for

January 9, 2012


Should you be able to read research you’ve helped to fund?

A few years ago, Congress approved an access policy that makes most taxpayer-funded research freely available online within 12 months of publication. It has proven a huge boon to researchers and the public.

Now, however, as UC Berkeley evolutionary biologist Michael Eisen relates, a proposed bill threatens to reverse this policy, Wired Scienceread more

Designer gene therapy may target specific body area

January 20, 2004

Doctors may soon be able to inject genetically engineered “designer” gene therapy intravenously that travels to a specific part of the body, according to Dr. Andrew H. Baker, molecular medicine researcher at the University of Glasgow,

Gene therapy involves inserting the treatment genes into a virus that is either harmless to humans or has had its disease-causing component removed. The virus is then injected or inserted into the body… read more

Advanced retinal implant developed

Advanced retinal implant

Bionic Vision Australia and University of New South Wales researchers have developed an advanced retinal implant to enable patients suffering from degenerative vision loss caused by retinitis pigmentosa and age-related macular degeneration to perceive points of light in the visual field that the brain can then reconstruct into an image.

The device consists of a miniature camera mounted on glasses that captures visual input, transforming it into… read more

World’s First Robotised Tele-Ultrasound Exam via Satellite

July 31, 2008

French firm Robosoft has announced the world’s first “robotized tele-ultrasound” examination via satellite.

In a demonstration, a doctor in France controlled a remote robot with an ultrasound probe to examine a patient on board a ship in the Mediterranean, using an Internet communication via satellite.

10 Tech Concepts You Need to Know for 2007

PRAM (Phase-Change Random Access Memory), Printed Solar Panels, Body Area Network, VoN (Video on the Net), and Data Cloud are among the technologies you’ll be talking about next year.

NIH scientists identify novel approach to view inner workings of viruses

January 13, 2012


Researchers at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health (NIH), have developed a new way to see structures within viruses that were not clearly seen before.

Cryo-electron microscopy (cryo-EM) is a technique that allows scientists to image very small particles, like structures on the surface of viruses. This method has been useful in helping… read more

A mouse that can regenerate its tissues

February 5, 2004

Researchers at the European Molecular Biology Laboratory and the University of Rome have found a way to mobilize stem cells to achieve a major regeneration of damaged tissue.

The scientists investigated muscle tissue in mice, discovering that stem cells can travel large distances to reach an injury. They also found a special form of a protein called mIGF-1 induces the muscle to send the distress signal that summons them.… read more

‘Mind-reading’ brain-scan software showcased in NY

April 8, 2010

Intel Corp. has introduced software that analyzes functional MRI scans to determine what parts of a person’s brain are being activated as he or she thinks, demonstrating 90 percent accuracy in guesses about which of two words a person was thinking about.

Artificial eyeball does away with distorted images

August 7, 2008
(University of Illinois)

University of Illinois at Urbana-Champagne researchers have built a hemispherical digital-image sensor that can take wide-angle pictures without distortion by mimicking the curves of a human retina.

They attached an array of silicon photodiodes on a curved “retina.”

The technology may make it possible to give the curved surface of a human retina a coat of digital sensors, helping blind people see again.

Snake-like Robot And Steady-hand System Could Assist Surgeons

December 27, 2006
Steady-hand robot

Johns Hopkins University researchers are designing new high-tech medical tools to equip the operating room of the future.

A snakelike robot could enable surgeons, operating in the narrow throat region, to make incisions and tie sutures with greater dexterity and precision.

Another robot, the steady-hand, may curb a surgeon’s natural tremor and allow the doctor to inject drugs into tiny blood vessels in the eye, dissolving… read more

F.C.C. Begins Rewriting Rules on Delivery of the Internet

February 13, 2004

The Federal Communications Commission began writing new rules today that officials and industry experts said would profoundly alter both the way the Internet is delivered and used in homes and businesses.

Commissioners are writing regulations to enable computer users to gain access to the Internet through electric power lines and to allow for new Internet phone services with fewer regulatory burdens than traditional phone carriers.
