Stanford analysts produce hereditary transistors, make biologic computing feasible
Author: Charity Woods
When constructing computer circuits, most folks start with silicon and metal, but not the researchers at Stanford. The boffins in Palo Alto want to build computers out of living tissue, and to that end they’ve created a biological transistor, called the transcriptor. Transcriptors substitute DNA for semiconductors and RNA for the electrons in traditional transistors — essentially, the transcriptor controls the flow of a specific RNA protein along a DNA strand using tailored combinations of enzymes. Using these transcriptors, researchers built logic gates to derive true/false answers to biochemical questions posed within living cells. Using these bio-transistors, researchers gain access to data not previously available (like whether an individual cell has been exposed to certain external stimuli), in addition to allowing them to control basic functions like cellular reproduction.
This new breakthrough — when combined with the DNA-based data storage and a method to transmit DNA between cells the school’s already working on — means that Stanford has created all the necessary components of a biologic computer. Such computers would allow man to actually reprogram how living systems operate. Of course, they haven’t built a living genetic PC just yet, but to speed up its development, the team has contributed all the transcriptor-based logic gates to the public domain. Looking to build your own biologic computer? A full explanation of the transcriptor awaits below.

Author: jos
In brief order, the Sequoia supercomputer and its 1.57 million processing centers will shift to a life of top-secret analysis at the National Nuclear Protection Administration, but till that day comes, analysts are presently working to ensure its seamless operation. Most lately, a group from Stanford took the helm of Sequoia to run computational fluid dynamics simulations– a process that requires a carefully tuned balance of computation, memory and communication parts– in order to better understand engine sound from supersonic jets. As a motivating sign, the group had the ability to effectively push the CFD simulation beyond 1 million cores, which is a first of its kind and bodes effectively for the scalability of the system. This and various other examinations are presently being performed on Sequoia as part of its “shakeout” period, which allows its caretakers to much better understand the capabilities of the IBM BlueGene/Q computer. Should all go well, Sequoia is arranged to begin a life of government work in March. In the meantime, you’ll discover a couple views of the setup after the break.

Stanford self-healing plastic responds to touch, keeps prosthetics and touchscreens in one piece
Author: Gabe Hall
Self-healing surfaces are theoretically the ideal solutions to quickly worn-out gadgets, but our dreams come crashing down as soon as purposeful contact is included; as existing products don’t perform electricity, they can not be made use of in capacitive touchscreens and other really logical locations. If Stanford University’s research into a new plastic polymer bears fruit, however, our scratched-up phones and tablets are much more likely to become remote memories. The product can recovery within moments of cuts with fast-forming hydrogen bonds, equaling some of its peers, but also consists of nanoscopic nickel bits that keep a present streaming as well as respond to bending or pressure. The material is uniquely created for the real world, too, with strength against multiple injuries and normal temperatures. While the polymer’s most apparent use would be for mobile gadgets whose whole area can easily survive the tricks in our pockets, Stanford additionally thinks of wires that fix themselves and prosthetic arm or legs whose skin detects when it’s bent out of shape. As long as we can easily accept that possible commercialization is years away, there’s hope that we eventually won’t have to handle our modern technology with children gloves to keep it looking pretty.

No Comments »Stanford Ovshinsky, inventor of the NiMH battery, passes away at 89
Author: Tiffany Shoman
On Wednesday night, Stanford Ovshinsky, creator of the nickel-metal hydride (NiMH) battery, died at the age of 89 due to complications from cancer. The Akron, Ohio native might not be a family name, but there’s a great opportunity that many of your electronics products have been powered by his work, as NiMH batteries are used in every little thing from mice to hybrid vehicles. A self-taught creator who didn’t go to university, Ovshinsky held hundreds of patents, got a number of honorary degrees and is even the namesake of a branch of electronics dubbed Ovonics. Flat-panel displays, solar cells and even phase modification memory are just a handful of additional technologies that his work assisted to establish. Next time you choose up a modern-day gizmo, simply keep in mind that Ovshinsky is partially liable for its presence.

Stanford researchers make heart implant powered by radio waves, put batteries out of a job
Author: Stefanie Jenkins
Batteries used to be the only way to power implantable gadgets, but additional surgeries are needed to replace the power packs once their juice runs out — a less-than-ideal solution for patients. Recent discoveries, however, have such medgadgets being powered by photons, hip hop and now high-frequency radio waves. Electrical engineers at Stanford built a cardiac device that uses a combination of inductive and radiative transmission of power, at about 1.7 billion cycles per second, to its coiled receiving antenna.
Previous prevailing opinion held that the high frequencies needed for wireless power delivery couldn’t penetrate the human body deep enough, and the lower frequencies that would do the trick require antennas too large to work as implants. That conundrum was solved by getting the high-frequency signals to penetrate deeper using alternating waves of electric and magnetic fields. That allowed a 10x increase in power delivery — up to 50 microwatts to a millimeter radius antenna coil — to an implant five centimeters below the skin. That antenna also was also designed to pull power regardless of its orientation, making it ideal for applications inside always-moving human bodies. Of course, the implant’s really just a proof-of-concept at this stage, but hopefully it won’t be long before battery powered implants go the way of the dodo TouchPad.

Stanford engineers find work around for barriers to carbon nanotube computers
Author: Buck Howard
We have actually been hanging around, rather patiently we could include, for carbon nanotubes to actually begin making a difference in our computing lives. That day has yet to pass, however specialists at Stanford are making excellent progression. Breakthroughs have been coming at a stable pace over the last many years, but there are still major barriers. For one, aligning tubes end to end has actually proven nearly impossible, and metallic carbon nanotubes (as opposed to semi carrying out ones) create all kinds of havoc with circuits. (That wouldn’t be an issue if there was a trustworthy method to generate just the semiconducting range.) Instead of charge headlong into those challenges though, the Stanford group has identified a way around modern restrictions, without losing a lot of the energy efficiency that makes carbon nanotubes so desirable. The team has found an “imperfection-immune” method of making nanotube circuits that takes out metallic impurities and is unaffected by crookeded tubes. For even more details, look into the PR after the break.

Stanford schooling unwashed masses with free online Intro to Artificial Intelligence (video)
Author: Christen Arquette
If you fancy yourself a Stanford (wo)man, but lack the requisite dollars to actually attend, now’s your chance to collect those collegiate bragging rights. Starting October 10th, you can join Professor Sebastian Thrun and Google’s Director of Research, Peter Norvig, in a free, online version of the school’s Introduction to Artificial Intelligence course. The class covers, “knowledge representation, inference, machine learning, planning and game playing, information retrieval, and computer vision and robotics,” and ambitiously aims to be the largest online AI course ever taught. If you’re feeling the ole red and white, you can register at the source link below, but if you’re looking for the official Stanford stamp of approval, we’re afraid you’re barking up the wrong tree — non-students will receive a certificate of completion from the instructors only. Still interested? Check out the video introduction after the break and hit the source for more details.
