Happy Accident Opens Door to Cheaper, Higher-Resolution Cameras

Scientific accidents have brought some of the most groundbreaking discoveries — vulcanized rubber, X-rays, penicillin — and now scientists at UCLA have accidentally discovered a material that could make digital cameras as we know them obsolete. Graduate student Hsiang-Yu Chen (of materials science and engineering) was working on a new formula for solar cells when something went wrong. Instead of creating electricity when hit with light, the conductivity of the material she was working with changed.

Websites shed light on how humans value fresh ideas

Analysing the rise and fall of websites is the perfect way to shed light on the old debate over whether talent or experience matters most, say mathematicians. The question crops up everywhere, from job interviews to presidential races, says Vwani Roychowdhury (UCLA professor of electrical engineering), but it’s hard to examine the problem using hard figures. However, the same way of thinking can be applied to websites, which also succeed or fail based on many millions of human decisions. In fact, the web may be one of the few places it is possible to quantify the balance between the two, say the researchers. (The research team included Roychowdhury, PhD student Joseph Kong and Nima Sarshar of the University of Regina, Canada.)

Nation’s Highest Scientific Honor given to Internet Father
Today, we take the existence of a high functioning internet for granted. In 1969, the basic technologies and processes that allow information to travel were just coming into being. Leonard Kleinrock, UCLA Distinguished Professor of Computer Science, has been selected to receive the National Medal of Science for his role in creating packet switching and the theory of data networks. His computer was one of the first nodes on the internet and he sent one of the very first emails. Love it or curse it, someone had to usher in the age of globalized communication.

Quick Takes: Muscle Heal Thyself

It’s too early to think about bulking up with the artificial muscles that scientists like Qibing Pei of UCLA’s Materials Science and Engineering Department in the Henry Samueli School of Engineering and Applied Science have been working on for years. But researchers are fantasizing that the rubber-like material, called electroactive polymers, may one day power small, energy-efficient robots, turn your shoes into power generators that can keep your iPod or cell phone going, power your car windows and adjust your car seats, and help keep a weak heart pumping.

Quick Takes: IPhone Home

Jonathan Zweig was 7 years old when he had an Einstein moment. One day he spotted an Atari gaming system in the trash. Zweig reacted to the battered machine with the same wonder that Einstein famously experienced when, at age 5, he saw his first magnetic compass. “I would play computer games after school and dream about making them,” recalls Zweig ’00, who majored in computer science and engineering. He did eventually make casual entertainment games — from brain teasers to mobile arcade games — and posted them on his Web site, Jirbo.com, where they could be downloaded for free. But he never imagined that his creations would change his whole life.

An Oral History of the Internet: How the Web Was Won

Fifty years ago, in response to the surprise Soviet launch of Sputnik, the U.S. military set up the Advanced Research Projects Agency. It would become the cradle of connectivity, spawning the era of Google and YouTube, of Amazon and Facebook, of the Drudge Report and the Obama campaign. Each breakthrough—network protocols, hypertext, the World Wide Web, the browser—inspired another as narrow-tied engineers, long-haired hackers, and other visionaries built the foundations for a world-changing technology. (The multimedia story features Distinguished Professor of Computer Science Leonard Kleinrock and alumnus Vinton Cerf MS ’70, PhD ’72.)

Number keys promise safer data

Sensitive computer files are to become both more secure and more flexible thanks to advanced mathematics. (Researchers) at the University of California in Los Angeles have applied a fundamental rethink to improve the “one lock – one key” method that current encryption technologies such as RSA and AES operate on. Amit Sahai, professor of computer science at the UCLA Henry Samueli School of Engineering and Applied Science, told BBC World Service’s Digital Planet programme that they had decided to “rebuild the idea from the ground up,” and developed the idea of multiple keys giving access to selected pieces of data.

News Bytes of the Week — Was the Red Baron Just Lucky?

Manfred Albrecht Freiherr von Richthofen, better known as the Red Baron, was the most feared German flying ace of World War I. He racked up 80 official air combat victories—the biggest winning streak on either side—before being shot down on April 21, 1918, over northern France. We’re inclined to interpret the Baron’s record as proof that he was the best of the best. But a study published in the Journal of Mathematical Sociology claims that much of Richthofen’s success could be chalked up to plain old luck. (the study’s authors are electrical engineering professor Vwani Roychowdhury and research engineer Mikhail Simkin.)

Discovery paves way for affordable and environmentally-friendly hydrogen vehicle

The findings of a study conducted by researchers at the UCLA Henry Samueli School of Engineering and Applied Science could one day lead to commercially practical designs of storage materials for use in hydrogen gas fuelled vehicles, it has been claimed. The study, which appeared on the Proceedings of the National Academy of Sciences (PNAS) web site on February 27th, expands on the finding in 1997 that adding titanium to sodium alanate not only lowers the temperature of hydrogen release from the material but also allows for an easy refueling and storage of high density hydrogen at reasonable pressures and temperatures.

Virtual Extras: Giving each member of a digital crowd its own personality could make animated mob scenes more realistic

The behavior of computer-generated crowds in movies and video games could soon appear much more realistic, thanks to new software that gives each character a complex personality of its own. The software has been demonstrated in a simulation of Pennsylvania Station, in New York City, depicting more than 1,000 commuters, law-enforcement officers, entertainers, and tourists going about their business. Each individual demonstrates complex, rational behaviors that collectively create a much more lifelike representation of human activity, says Demetri Terzopoulos, a professor of computer science at the University of California, Los Angeles.
