New heat-recovery system makes Stanford one of world’s most energy-efficient uni's

At Stanford University in California, it’s normally the Nobel-winning researchers who make the news. But with the commissioning of a novel renewable energy system, the campus’s humble heating and cooling system has grabbed some headlines. Using a first-of-its-kind heat recovery system, and drawing a substantial percentage of its electricity from solar, the university is greening up its operations in a move that will see greenhouse gas emissions cut by 68 percent and fossil fuel use cut by 65 percent.

Brain4Cars system could spot driver errors before they happen

We keep hearing about systems designed to either alert drivers to impending collisions, to let them know that they've made a mistake (such as drifting out of their lane), or to tell them that they're getting tired. Brain4Cars, however, takes yet another approach. Created by scientists at Cornell and Stanford universities, it monitors drivers to determine when they're about to do something wrong, so it can warn them not to. Read More

Bird-inspired self-folding wings could help drones recover from collisions

If you've ever watched a flying bird weaving its way through a forest, you may have wondered how it could do so without hitting its wings on the trees. Well, birds actually do hit trees with their wings. Unlike the rigid wings of an aircraft, however, birds' wings simply fold back under impact, then immediately fold open again to maintain flight. Now, scientists from Stanford University have developed wings for flapping-wing drones that do the same thing. Read More

Low-cost air filter could help Beijing breathe easy

Material scientists at Stanford University have developed a highly effective semitransparent air filter that can collect 99 percent of the very small PM2.5 particles, considered the most harmful to the human respiratory tract. The low-cost filters, which don’t require power to function, could be used to build better protective facemasks, window screens, filtration systems in hospitals, and perhaps even to reduce pollution from cars and industrial smoke stacks.

Telomere-lengthening procedure turns clock back years in human cells

Researchers at the Stanford University School of Medicine have developed a new procedure to increase the length of human telomeres. This increases the number of times cells are able to divide, essentially making the cells many years younger. This not only has useful applications for laboratory work, but may point the way to treating various age-related disorders – or even muscular dystrophy. Read More

Smaller, faster, greener "high-rise" 3D chips are ready for Big Data

Stanford engineers have pioneered a new design for a scalable 3D computer chip that tightly interconnects logic and memory, with the effect of minimizing data bottlenecks and saving on energy usage. With further work, the advance could be the key to a very substantial jump in performance, efficiency, and the ability to quickly process very large amounts of information  –  known as "Big Data"  –  over conventional chips.Read More

Mirror coating to cool buildings by pumping interior heat into space

Keeping buildings cool isn't easy. In fact, conventional air conditioning methods are very energy intensive and account for up to 15 percent of the energy used in buildings in the United States alone. However, engineers at Stanford University have come up with a new ultrathin, multilayered, nanophotonic material that not only reflects heat away from buildings, but also directs heat from inside out into space, cooling both the building and the planet as well.Read More

Stanford researchers develop earthquake-resistant house prototype

Though a large earthquake can prove catastrophic to life and property, even relatively minor tremors may compromise the structural integrity of a home, resulting in large repair costs. A team of engineers based at California's Stanford University has developed a new method of building earthquake-resistant homes that could be implemented relatively easily and inexpensively.
