Stamp out common virus to beat brain cancer

May 27, 2008

Duke University Medical Center treated brain tumors known as glioblastomas by taking white blood cells from 21 patients, exposing them to parts of the cytomegalovirus (often found in these cancers), and injecting the cells back into the patients. Their preliminary results suggest that this technique is safe and effective.

“Because the immune system kills both the virus and the cell it resides in, we are hoping that… read more

Stamp-Size Plastic Chip Provides New Approach to Cryptography

September 22, 2002

Modern encryption techniques are tested every time someone makes a purchase over the Internet or spends electronic cash stored in smart cards. These strategies rely on so-called one-way functions, which are easy to execute in one direction (for instance, multiplying two prime numbers) but difficult to reverse (factoring a large number into two primes). With ever-increasing computer power and advances in quantum computing, however, such methods may soon become breakable.… read more

Stamping out low-cost nanodevices

June 1, 2011

SEM Gold

A simple technique for stamping patterns invisible to the human eye onto a special class of nanomaterials has been developed by researchers at Vanderbilt University.

The new method works with porous nanomaterials that are riddled with tiny voids, which give them unique optical, electrical, chemical, and mechanical properties. There are nanoporous forms of gold, silicon, alumina, and titanium oxide, among others.

The technique involves the… read more

‘Stamping’ self-assembling nanowires

October 20, 2008

Cornell researchers have created an innovative way to make and pattern nanoscale wires and other devices without requiring expensive lithographic tools; uses include computer memory and circuits, and quantum dots.

They coated gold nanoparticles suspended in water with a synthetic-DNA-based ligand that adheres to the metal and to water. Adjusting the DNA lengths can precisely control the distance between the particles to make them assemble into orderly superlattices, rather… read more

Stamps create DNA nanoarrays

December 15, 2005

Ohio State University researchers have come up with a modified molecular combing technique for creating arrays of stretched DNA molecules that could have applications in nanoelectronics, biological or chemical sensors, and genetic analysis and medical diagnosis.

By patterning a large quantity of stretched DNA molecules into a well-defined array of nanowires, parallel and automated analysis may be realized to achieve higher throughput and reliability, they believe.

Standing in Someone Else’s Shoes, Almost for Real

December 2, 2008

Neuroscientists have presented evidence that they can create a “body swapping” illusion by using VR helmets, showing that the brain, when tricked by optical and sensory illusions, can quickly adopt any other human form, no matter how different, as its own.

Based on virtual-reality experiments, the technique could have a profound effect on a range of therapeutic techniques. In these studies, researchers create avatars that mimic a person’s every… read more

Stanford announces $100 million energy institute

January 14, 2009

Stanford University has received $100 million to create a new energy institute where scholars can study everything from solar cells to energy markets and economics.

Stanford bioengineers close to brewing opioid painkillers

A decade-long effort in genetic engineering is close to re-programming yeast cells to make palliative medicines
August 27, 2014

tanford Bioengineer Christina Smolke has been on a decade-long quest to genetically alter yeast so they can "brew" opioid medicines in stainless steel vats, eliminating the need to raise poppies and then industrially refine derivatives of opium into pain pills. (Credit: Poppy image created by Rachel Sakai)

Stanford bioengineers have hacked the DNA of yeast, reprograming these simple cells to make opioid-based medicines* via a sophisticated extension of the basic brewing process that makes beer.

Led by Associate Professor of Bioengineering Christina Smolke, the Stanford team has already spent a decade genetically engineering yeast cells to reproduce the biochemistry of poppies, with the ultimate goal of producing opium-based medicines, from start to… read more

Stanford builds a better virtual world, one tree (or millions) at a time

January 8, 2008

Stanford researchers are out to prove that object construction in virtual worlds can be sophisticated without being difficult.

Stanford engineers discover neural rhythms drive physical movement

June 4, 2012

stanford_brain_rythms

In a significant departure from earlier models, neural engineers and neuroscientists working at Stanford University have developed a new model for the brain activity underlying arm movements: motor neurons do not represent external-world parameters as previously thought, but rather send a few basic rhythmic patterns down the spine to drive movement.

The finding has implications in prosthetics, the understanding of motor disorders and other uses… read more

Stanford engineers perfecting carbon nanotubes for highly energy-efficient computing

Could provide a ten-times improvement in energy efficiency over silicon
June 17, 2012

carbon_nanotubes_stanford

Stanford Unversity engineers have produced the first full-wafer digital logic structures based on carbon nanotubes (CNTs).

Circuits based on CNTs could provide a ten-times improvement in energy efficiency over silicon, according to the engineers.

Background: dealing with chip energy efficiency with CNTs
Energy efficiency is the most significant challenge standing in the way of continued miniaturization of electronic systems, and miniaturization is the principal driver of the semiconductor… read more

Stanford University researchers are enrolling participants in a pioneering study investigating the feasibility of allowing people with paralysis to use a technology that interfaces directly with the brain to control computer cursors, robotic arms and other assistive devices.

Those eligible to enroll in the trial include people with weakness of all four limbs resulting from cervical spinal cord injury, brainstem stroke, muscular dystrophy, or motor… read more

Stanford lab launches new privacy-based social network

With rising public interest in what developers refer to as the “privacy economy,” researchers from the MobiSocial Lab at the Stanford School of Engineering have announced at SXSW a new type of social network, called Omlet that allows users to control their own personal data.

Omlet “shields users from the monetization of their personal lives by giving them total and unquestioned control of their personal… read more
