Reconsidering the Global Thermostat

10-24-12

Doug MacMartin, Senior Research Associate in Computing and Mathematical Sciences, and colleagues have shown that the outcome of geoengineering can be tunable. Geoengineering is the concept of how the planet's climate could be manipulated to counteract the effects of global warming. Using computer modeling, they have shown that varying the amount of sunlight deflected away from the earth by season and by region can significantly improve the parity of the situation.

Clean-Energy Research Accelerates

10-22-12

Caltech clean-energy research is accelerating thanks to the renovation of the Earle M. Jorgensen Laboratory. Transformed into a cutting-edge facility for energy science, the lab unites two powerhouse programs: the Resnick Sustainability Institute and the Joint Center for Artificial Photosynthesis (JCAP). "Our researchers are working with Caltech's chemists and chemical engineers to challenge the status quo and translate scientific discovery into clean-energy innovations that will directly benefit society for generations to come," says Chair Ares Rosakis.

Developing the Next Generation of Microsensors

10-19-12

Oskar J. Painter, Professor of Applied Physics; Executive Officer for Applied Physics and Materials Science; and Co-Director, Kavli Nanoscience Institute, and colleagues have engineered a microscale optical accelerometer. In addition to transforming consumer electronics, such sensors could help with oil and gas exploration deep within the earth, could improve the stabilization systems of fighter jets, and could even be used in some biomedical applications where more traditional sensors cannot operate. "Professor Painter's research in this area nicely illustrates how the Engineering and Applied Science faculty at Caltech are working at the edges of fundamental science to invent the technologies of the future," says Chair Ares Rosakis.

Taming Turbulence

08-29-12

"Turbulence is everywhere," says Professor Beverley McKeon—from continent-spanning weather systems down to the swirls of air your car leaves behind itself as you drive. "I think about things like ships, planes, and pipelines," she explains, noting that about half of the energy consumed by each of those three transportation systems goes to counteract turbulence-induced drag. In her Watson Lecture she notes that finding a way to reduce that turbulence by 30 percent would save the global economy well over $100,000,000 dollars in fuel costs annually. [Learn More]

Solar Loops and Space Weather

08-20-12

Paul M. Bellan, Professor of Applied Physics, and colleagues have reproduced plasma loops in the laboratory to help understand solar physics. "We're studying how these solar loops work, which contributes to the knowledge of space weather," says Professor Bellan, who compares the research to studying hurricanes. For example, you can't predict a hurricane unless you know more about the events that precede it, like high-pressure and low-pressure fronts. The same is true for solar flares. "It takes some time for the plasma to get to Earth from the sun, so it's possible that with more research, we could have up to a two-day warning period for massive solar flares."

Self-Contained, Photovoltaic Powered Domestic Toilet

08-15-12

Michael Robert Hoffmann, James Irvine Professor of Environmental Science, and his team of graduate students Asghar Aryanfar, Clement Cid, Kangwoo Cho, Daejung Kwon, and Hao Zhang, along with post doctoral scholar Yan Qu have won the Reinventing the Toilet Challenge issued by the Bill and Melinda Gates Foundation. Their winning proposal was to build a toilet that uses the sun to power an electrochemical reactor. The reactor breaks down water and human waste into fertilizer and hydrogen, which can be stored in hydrogen fuel cells as energy. The treated water can then be reused to flush the toilet or for irrigation. [Caltech Feature] [CNN Ideas]

Professor Kitaev Receives $3M Fundamental Physics Prize

07-31-12

Alexei Y. Kitaev, Professor of Theoretical Physics, Computer Science, and Mathematics, has received the $3 million Yuri Milner Fundamental Physics Prize. The prize citation recognizes Professor Kitaev's "theoretical idea of implementing robust quantum memories and fault-tolerant quantum computation using topological quantum phases with anyons and unpaired Majorana modes."  This new prize is the most lucrative academic prize in the world and Professor Kitaev is one of only nine scientists to receive it this year.

Seeing Inside Tissue

06-26-12

Changhuei Yang, Professor of Electrical Engineering and Bioengineering, and colleagues Ying Min Wang and Benjamin Judkewitz have developed a new method to focus light inside biological tissue. "It enables the possibilities of doing incision-less surgery," says Professor Yang. "By generating a tight laser-focus spot deep in tissue, we can potentially use that as a laser scalpel that leaves the skin unharmed." [Caltech Press Release]
