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.

A display that lets users manipulate on-screen images using hand gestures has been developed by the MIT Media Lab.

Doubt cast on source of universe’s mightiest particles

May 14, 2008

Stanford University researchers have found that black holes in nearby galaxies are not a likely source of ultra-high-energy cosmic rays (UHECR).

Instead, UHECRs are more likely to come from the more energetic breeds of an active galaxy, such as quasars and radio galaxies.

Does This Mean People Turned Off, Tuned Out and Dropped In?

June 30, 2006

Speakers of Aymara, an Indian language of the high Andes, think of time differently than just about everyone else in the world. They see the future as behind them and the past ahead of them.

Cyber threats 2012: search poisoning, mobile Web attacks, selling social-media data

October 12, 2011

The year ahead will feature new and increasingly sophisticated means to capture and exploit user data, as well as escalating battles over the control of online information that threatens to compromise content and erode public trust and privacy.

Those were the findings announced by the Georgia Tech Information Security Center (GTISC) and the Georgia Tech Research Institute (GTRI) in the Georgia Tech Emergingread 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

Snap and Search (No Words Needed)

December 21, 2009

Google’s massive data centers with their computing power and more than a billion images allow its Goggles image-recognition smartphone app to recognize millions of images.

Methuselah Foundation Announces Aging 2008 at UCLA

May 19, 2008

On Friday June 27th, leading scientists and thinkers in stem cell research and regenerative medicine will gather in Los Angeles at UCLA for Aging 2008 to explain how their work can combat human aging, and the sociological implications of developing rejuvenation therapies.

Aging 2008 is free, with advance registration required.

Dr. Aubrey de Grey, chairman and chief science officer of the Methuselah Foundation, said “Our organization… read more

‘Lab-made sperm’ fertility hope

July 12, 2006

Scientists have proved for the first time that sperm grown from embryonic stem cells can be used to produce offspring.

Scientists create modular logic gates from bacteria and DNA

October 19, 2011

DNA-based AND gate

Imperial College London researchers have demonstrated that they can build AND, NOT, and NAND digital logic gates out of E-coli bacteria and DNA, which could lead to a new generation of biological computing devices that, for example, swim inside arteries, detecting the buildup of harmful plaque and rapidly deliver medications to the affected zone.

The scientists constructed an AND gate from E.Coli bacteria and altered the E.Coli… 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.

Controlling the TV with a wave of the hand

December 24, 2009

Consumer devices for 3D gesture recognition for controlling TVs, videogames, and personal computers, using a camera in real time to capture motion, are coming in 2010 from a number of companies, including Softkinetic/Texas Instruments and Microsoft.

Brain’s ‘trust machinery’ identified

May 22, 2008

The brain centers triggered by a betrayal of trust have been identified by researchers, who found they could suppress such triggering and maintain trust by administering the brain chemical oxytocin.

The researchers said their findings not only offer basic insights into the neural machinery underlying trust; the results may also help in understanding the neural basis of social disorders such as phobias and autism.

Scientists to build ‘brain box’

July 19, 2006

The “brain box,” being built by University of Manchester scientists, will use large numbers of microprocessors to model the way networks of neurons interact.

Genetic variant may protect those at high risk for Parkinson’s disease

October 26, 2011

The serum/glucocorticoid regulated kinase 1 (SGK1) gene appears to be protective against a high-risk leucine-rich repeat kinase 2 (LRRK2) mutation for Parkinson’s disease, 23andMe, a personal genetics company, has discovered.

Of the approximately 1 in 10,000 people who carry a mutation called G2019S on the LRRK2 gene, about half develop Parkinson’s disease. Scripps Research Institute will further investigate the SGK1 gene as a first step… read more
