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

The Tohoku University design would change shape during flight to adapt to supersonic speed...

A throwback to early 20th Century aviation may hold the key to eliminating the sonic boom - at least according to researchers at MIT and Stanford University. Strongly reminiscent of biplanes still in use today, the researcher's concept supersonic aircraft introduces a second wing which it is claimed cancels the shockwaves generated by objects near or beyond the sound barrier.  Read More

Wirelessly powered self propelled medical implants could be used to transport drugs and se...

With the wait still on for a miniaturization ray to allow some Fantastic Voyage-style medical procedures by doctors in submarines, tiny electronic implants capable of traveling in the bloodstream show much more promise. While the miniaturization of electronic and mechanical components now makes such devices feasible, the lack of a comparable reduction in battery size has held things back. Now engineers at Stanford University have demonstrated a tiny, self-propelled medical device that would be wirelessly powered from outside the body, enabling devices small enough to move through the bloodstream.  Read More

For those unfamiliar with the term, a “whispering gallery” is a round room designed in such a way that sound is carried around its perimeter – this allows a person standing on one side to hear words whispered by a person on the other. Now, scientists from Stanford University have developed a new type of photovoltaic material, that essentially does for sunlight what whispering galleries do for sound. Not only does the material have a structure that circulates light entering it, but it could also result in cheaper, less fragile, and less angle-sensitive solar panels.  Read More

One of the nanowire meshes, created by the Stanford scientists

Some day, meshes made from nanowires could be used in devices such as video displays, LEDs, thin-film solar cells, and touch-screens. According to research performed so far, such meshes would be very electrically conductive, cost-effective, and easy to process. What has proven challenging, however, is finding a way of getting the criss-crossed nanowires to fuse together to form that mesh – if pressed or heated, the wires can be damaged. Now, engineers from Stanford University may have found the answer ... just apply light.  Read More

By charging while you're driving, you'll get more range without even stopping

The greatest obstacle standing in the way of electric-vehicle adoption - besides crafty, deceitful right wingers - is limited range. Electric vehicles can only travel 100 miles (161 km) on their best day. Because of the lack of electric charging stations and the amount of time involved in charging a battery, they just can't go as far as gas vehicles. A team of researchers at Stanford University recently made an important discovery in wireless charging technology. Their work could one day help solve the limited-range dilemma.  Read More

A new electrode developed at Stanford University could enable batteries that are big and e...

There's no doubt that sources of renewable energy such as wind and solar are critical to a clean energy future, but just as important is a way to store the energy generated for use when the sun isn't shining and the wind isn't blowing. Researchers at Stanford University are reporting the development of a new high-power electrode that is so cheap, durable and efficient that it could enable the creation of batteries that are big enough and economical enough for large-scale storage of renewable energy on the grid.  Read More

Stanford's stretchable pressure-sensitive material incorporates coatings of tiny 'nano-spr...

Robots, prosthetic limbs and touchscreen displays could all end up utilizing technology recently developed at California’s Stanford University. A team led by Zhenan Bao, an associate professor of chemical engineering, has created a very stretchy skin-like pressure-sensitive material that can detect everything from a finger-pinch to over twice the pressure that would be exerted by an elephant standing on one foot. The sensitivity of the material is attained through two layers of carbon nanotubes, that act like a series of tiny springs.  Read More

A new form of superhard carbon discovered by scientists could have advantages over diamond...

Carbon is the fourth-most-abundant element in the universe and comes in a wide variety of forms, called allotropes, including graphite, graphene, and the hardest natural material known to man, diamonds. Now scientists have discovered a new form of carbon that is capable of withstanding extreme pressure stresses previously only observed in diamond. Unlike crystalline forms of carbon such as diamonds, whose hardness is highly dependent upon the direction in which the crystal is formed, the new form of carbon is amorphous meaning it could be equally strong in all directions.  Read More
