State Legislators Honor Frances Arnold

Caltech chemistry professor Frances Arnold will be honored by the California Legislative Women's Caucus at its inaugural Breaking the Glass Ceiling awards ceremony in Sacramento, California, on March 4.

The ceremony, to be held in the Assembly chambers at the California State Capital, is part of the Legislative Women's Caucus commemoration of Women's History Month. Following the ceremony, Arnold and other awardees will attend a reception at the governor's office.

Visualizing Biological Networks in 4D

Every great structure, from the Empire State Building to the Golden Gate Bridge, depends on specific mechanical properties to remain strong and reliable. Rigidity—a material's stiffness—is of particular importance for maintaining the robust functionality of everything from colossal edifices to the tiniest of nanoscale structures. In biological nanostructures, like DNA networks, it has been difficult to measure this stiffness, which is essential to their properties and functions. But scientists at the California Institute of Technology (Caltech) have recently developed techniques for visualizing the behavior of biological nanostructures in both space and time, allowing them to directly measure stiffness and map its variation throughout the network.

Caltech Senior Wins Churchill Scholarship

Caltech senior Andrew Meng has been selected to receive a Churchill Scholarship, which will fund his graduate studies at the University of Cambridge for the next academic year. Meng, a chemistry and physics major, was one of only 14 students nationwide who were chosen to receive the fellowship this year.

Arnold Awarded National Medal of Technology and Innovation

Frances H. Arnold, a leader in the field of protein engineering and a member of the faculty at Caltech, was one of 11 inventors to be awarded the 2011 National Medal of Technology and Innovation. President Barack Obama presented Arnold with the medal on February 1 in a ceremony in the East Room of the White House.

Jorgensen Laboratory Awarded LEED Platinum Certification

The recent renovations of the Jorgensen Laboratory included many upgrades that were designed to reflect Caltech's commitment to sustainability. Now the building has achieved LEED Platinum certification, the highest honor of the U.S. Green Building Council.

TEDxCaltech: Surmounting the Blood-Brain Barrier

The brain needs its surroundings to be just right. That is, unlike some internal organs, such as the liver, which can process just about anything that comes its way, the brain needs to be protected and to have a chemical environment with the right balance of proteins, sugars, salts, and other metabolites.

Caltech Chemical Engineer Frances Arnold Awarded National Medal of Technology and Innovation

Frances H. Arnold, a leader in the field of protein engineering and a member of the faculty at the California Institute of Technology (Caltech) has been named one of 11 inventors who are the recipients of the 2011 National Medal of Technology and Innovation. The announcement was made by the White House on December 21.

Unlocking New Talents in Nature

Protein engineers at Caltech have tapped into a hidden talent of one of nature's most versatile catalysts. The enzyme cytochrome P450 is nature's premier oxidation catalyst—a protein that typically promotes reactions that add oxygen atoms to other chemicals. Now the Caltech researchers have engineered new versions of the enzyme, unlocking its ability to drive a completely different and synthetically useful reaction that does not take place in nature.

Theodor Agapie Wins American Chemical Society Award

Theodor Agapie, assistant professor of chemistry at Caltech, has received the 2013 Award in Pure Chemistry from the American Chemical Society (ACS). The award will be presented at the national meeting of the ACS in New Orleans in April.

ACS is recognizing Agapie for his laboratory research on inorganic compounds. According to Agapie, his lab is working toward developing catalysts for artificial photosynthesis, a promising area of research into sustainable energy.

Caltech Modeling Feat Sheds Light on Protein Channel's Function

Chemists at Caltech have managed, for the first time, to simulate the biological function of a channel called the Sec translocon, which allows specific proteins to pass through membranes. The feat required bridging timescales from the realm of nanoseconds all the way up to full minutes, exceeding the scope of earlier simulation efforts by more than six orders of magnitude. The result is a detailed molecular understanding of how the translocon works.
