A green, rechargeable battery that is suitable for powering electric vehicles and stationary power storage applications, and that would survive tens of thousands of charge cycles in a useful life of 100 years without loss of capacity. What could be a better innovation for our times? Such a battery has been developed, and recently improved by Stanford researchers. Oh, one other thing. The battery was invented by Thomas Edison in 1901.  Read More

Researchers at Stanford University have created an electrically conductive gel that feels and behaves like biological tissues, but conducts electricity like a metal or semiconductor. The gel can also be printed or sprayed as a liquid before being turned into a gel. The researchers say this combination of characteristics gives the gel enormous promise for developing new biological sensors and energy storage devices.  Read More

Tech startup Neurovigil announced last April that Stephen Hawking was testing the potential of its iBrain device to allow the astrophysicist to communicate through brainwaves alone. Next week Professor Hawking and iBrain inventor, Dr Philip Low from Stanford University, present their findings at the Francis Crick Memorial Conference in Cambridge, England. In anticipation, Gizmag spoke to Dr Low about the potential applications of the iBrain.  Read More

After decades of trial and error, artificial intelligence applications that aim to understand human language are slowly starting to lose some of their brittleness. Now, a simple mathematical model developed by two psychologists at Stanford University could lead to further improvements, helping transform computers that display the mere veneer of intelligence into machines that truly understand what we are saying.  Read More

Stanford researchers have found that concentric carbon nanotubes, with the outer layer riddled by defects and impurities, could be a cheap alternative for some of the platinum catalysts that convert hydrogen and oxygen into water in fuel cells and metal-air batteries.  Read More

A new retinal prosthesis could allow the blind to see, by using pulses of near-infrared li...

Age-related macular degeneration is the leading cause of blindness in North America, while retinitis pigmentosa causes approximately 1.5 million people worldwide to lose their sight every year. Individuals afflicted with retinal degenerative diseases such as these might someday be able to see again, however, thanks to a device being developed at California’s Stanford University. Scientists there are working on a retinal prosthesis, that uses what could almost be described as miniature solar panels to turn light signals into nerve impulses.  Read More

A cut-away view of the LSST camera, with a person for scale

Although the pixel count for consumer cameras continues to rise, they will all pale in comparison to the 3,200-megapixel Large Synoptic Survey Telescope (LSST) camera. Although the enormous astronomical camera has yet to be built, last week the U.S. Department of Energy gave its approval for the project to proceed to the next phase of development. This means that a detailed engineering design can begin, along with a production schedule and budget. If everything goes according to plan, construction on what will be the world’s largest digital camera should begin in 2014.  Read More

A nanowire sporting tendrils of nanoparticles, which greatly add to its surface area

Higher-density batteries, more efficient thin-film solar cells, and better catalysts may all soon be possible, thanks to a new technique that allows nanowires to be “decorated” with nanoparticles. Using the novel technology, scientists from Stanford University have been able to festoon the outside surfaces of nanowires with intricate chains of metal oxide or noble metal nanoparticles, thereby drastically boosting the effective surface area of the nanowires. Other researchers have previously tried to achieve the same end result, but apparently never with such success.  Read More

In addition to an MRI (pictured), gold nanoparticles allow a brain tumor to be imaged phot...

Scientists at Stanford University’s School of Medicine have created nanoparticles that are able to precisely highlight brain tumors. Because the nanoparticles can be imaged in three different ways, they can be used to delineate the boundaries of tumors before and during brain surgery to ease the complete removal of tumors. The scientists have already used the nanoparticles to remove brain tumors from mice with unprecedented accuracy and hope the technique could be used on humans in the future.  Read More

Lithium atoms (red) deposited on graphene were shown to give the material piezoelectric qu...

Scientists have succeeded in endowing graphene with yet another useful property. Already, it is the thinnest, strongest and stiffest material ever measured, while also proving to be an excellent conductor of heat and electricity. These qualities have allowed it to find use in everything from transistors to supercapacitors to anti-corrosion coatings. Now, two materials engineers from Stanford University have used computer models to show how it could also be turned into a piezoelectric material – this means that it could generate electricity when mechanically stressed, or change shape when subjected to an electric current.  Read More
