Caltech senior Wilson Ho spent his summer completing a SURF project in the lab of Robert Grubbs, one of the winners of the 2005 Nobel Prize in Chemistry. Ho tells his nonscientist friends and family that the goal of his project is to develop "stem-cell Band-Aids" that might one day help restore vision in those suffering from macular degeneration.
In the last couple of years, researchers have observed that water spontaneously flows into extremely small tubes of graphite or graphene, called carbon nanotubes. However, no one has managed to explain why. Now, using a novel method to calculate the dynamics of water molecules, Caltech researchers believe they have solved the mystery. It turns out that entropy, a measurement of disorder, has been the missing key.
Nobel Laureate Ahmed Zewail, Pauling Professor of Chemistry and professor of physics, has received the Royal Society's Davy Medal "for his seminal contributions to the study of ultrafast reactions and the understanding of transition states in chemistry, and to dynamic electron microscopy."
For biochemist and chemical engineer Frances Arnold, the road to success has not been straight and narrow. In fact, she has often bucked the academic tradition of rigorous, time-consuming pre-experiment methodology for a more fast and furious approach to research.
There's a wealth of health information hiding in the human immune system. Accessing it, however, can be very challenging, as the many and complex roles that the immune system plays can mask the critical information that is relevant to addressing specific health issues. Now, research led by scientists from the California Institute of Technology (Caltech) has shown that a new generation of microchips developed by the team can quickly and inexpensively assess immune function.
Dr. John P. Holdren, assistant to the president for science and technology, director of the White House Office of Science and Technology Policy, and co-chair of the President's Council of Advisors on Science and Technology (PCAST), will be the speaker at the 2011 DuBridge Distinguished Lecture Series at the California Institute of Technology (Caltech).
Renowned chemist and Nobel laureate Ahmed Zewail, Linus Pauling Professor of Chemistry and professor of physics at the California Institute of Technology (Caltech), will be the speaker for Caltech's 117th annual commencement ceremony, which will take place at 10 a.m. on June 10 of this year.
Frances Arnold has been named co-recipient of the Charles Stark Draper Prize by the National Academy of Engineering. She was awarded the $500,000 prize—the engineering profession's highest honor—for a method called directed evolution, used worldwide to guide the creation of certain properties in proteins and cells, allowing the engineering of novel enzymes and biocatalytic processes for pharmaceutical and chemical products.
A team of scientists led by researchers from Caltech and JPL have fully characterized a key chemical reaction that affects the formation of pollutants in smoggy air. The findings suggest that in the most polluted parts of Los Angeles—and on the most polluted days in those areas—current models are underestimating ozone levels, by between 5 to 10 percent.
