A Business Out of Thin Air

August 4, 2003

HoloTouch has developed technology that allows users to operate equipment simply by passing a finger through a holographic image.

The system uses lasers and infrared sensors to create images that can be manipulated in the air.

Photos: Five mobiles of the future unveiled

August 21, 2009

Nanotech-based materials with radically different properties will be the basis of tomorrow’s mobile phones. becoming more flexible and stretchable yet still strong, for example, in the case of Nokia’s Morph concept.


In search of a robot more like us

July 12, 2011

ARM Robot

The Defense Advanced Research Projects Agency is underwriting three competing efforts by SRI International, Sandia National Laboratories, and iRobot to develop robotic arms and hands one-tenth as expensive as today’s systems (which often cost $100,000 or more).

Designing a robot to mimic the basic capabilities of motion and perception would be revolutionary, researchers say, with applications stretching from care for the elderly to returning overseas manufacturing operations to… read more

Ericsson predicts swift end for Wi-Fi hotspots

March 11, 2008

“Hotspots at places like Starbucks are becoming the telephone boxes of the broadband era,” claimed Ericsson’s chief marketing officer Johan Bergendahl, citing the rapid growth of mobile broadband.

Electronic ‘Etch A Sketch’ may boost quantum design

August 15, 2003

Erasable electrostatic lithography (EEL), uses an atomic force microscope to draw, modify, or erase a circuit by depositing spots of charge directly on to the surface of a semiconductor. It could significantly speed the design of quantum electronic devices.

Drug enables deafened mice to hear again

January 10, 2013


All you graying, half-deaf Def Leppard fans, listen up. A drug applied to the ears of mice deafened by noise can restore some hearing in the animals, Science Now reports.

By blocking a key protein, the drug allows sound-sensing “hair cells” damaged by loud noises to regrow. The treatment isn’t anywhere near ready for use in humans, but the advance at least raises the prospect of restoring… read more

Fishy Sixth Sense: Mathematical Keys To Fascinating Sense Organ

August 31, 2009

Fish and some amphibians possess a unique sensory capability in their “lateral-line system” (using several thousand neuromasts) that detects changes in water currents, allowing them to sense objects without direct physical contact or to “see” in the dark, Technische Universitaet Muenchen physicists have found.

The research may help endow robots with additional sensors for sound and touch, allowing them to move safely among crowds of people or orient themselves… read more

Killer tomatoes attack human diseases

June 30, 2006

Genetically modified tomatoes containing edible vaccine are to be used to challenge two of the world’s most lethal viruses, HIV and the hepatitis B virus, by manufacturing proteins to prompt the body to create antibodies against the viruses.

MicroRNAs help zebrafish regenerate fins

March 17, 2008

Duke University Medical Center biologists have discovered a molecular switch that controls a zebrafish’s ability to regenerate organs and tissues, including hearts, eye parts and fins.

In zebrafish, one or more microRNAs appear to keep regeneration on hold until the fish needs new tissue. In response to an injury, the fish reduce levels of these microRNAs to aid regrowth.

The researchers believe that mammals may have the same… read more

Ocean Sponge May Be Best for Fiber Optics

August 25, 2003

Scientists have identified an ocean sponge living in the deep sea that grows thin glass fibers capable of transmitting light at least as well as industrial fiber optic cables.

Materials scientists hope to duplicate the growth process to avoid problems with current fiber optic manufacturing methods that require high temperatures and produce relatively brittle cable.

Other recent biomimetics discoveries include an enzyme that improves laundry detergent, a glowing… read more

For Teens, Has Texting Replaced Talking?

September 7, 2009

Teenagers with cellphones each send and receive 2,272 text messages a month on average, Nielsen Mobile says.

A Tissue Engineer Sows Cells and Grows Organs

July 11, 2006

Tissue-engineering researchers are working on tissue replacement projects for practically every body part — blood vessels and nerves, muscles, cartilage and bones, esophagus and trachea, pancreas, kidneys, liver, heart and even uterus.

A more immediate goal is to improve upon a multitude of smaller therapies: transplantable valves for ailing hearts, cell-and-gel preparations for crushed nerves, injections of skeletal muscle cells for urinary continence or new salivary gland tissue to… read more

Scientists Set Sights on an Implantable Prosthetic for the Blind

March 19, 2008
John Pezaris

A Massachusetts General Hospital neuroscientist is designing a prosthetic to bypass eyes and optic nerves and send image information directly to the regions of the brain that process them.

The prosthesis proposed by John Pezaris would be worn like a pair of glasses, with digital cameras over a person’s eyes connecting to an array of electrodes implanted in the brain.

In research published in 2007 he… read more

Researchers Measure The Electrical Resistance Of Single Molecules

September 2, 2003

Researchers at Arizona State University have developed a relatively straightforward method for measuring the electrical resistance of single molecules. The advance promises to have a huge impact on the burgeoning field of molecular electronics.
