National Inventors Hall of Fame to Induct Frances Arnold

Frances H. Arnold, the Dick and Barbara Dickinson Professor of Chemical Engineering, Bioengineering and Biochemistry, and director of the Donna and Benjamin M. Rosen Bioengineering Center at Caltech, is one of five living innovators chosen to be inducted into the National Inventors Hall of Fame in 2014.

A Changing View of Bone Marrow Cells

Using a novel microfluidic technique, researchers at Caltech have shown that blood stem cells might be more actively involved in battles against infection. Rather than simply replenishing immune cells after they become depleted, new research shows that blood stem cells sense danger signals directly and quickly produce new immune cells.

Watching the Brain Do Its Thing: An Interview with Mikhail Shapiro

To a large extent, the brain remains a black box. Taking it out of its case inside the skull and examining it—as in an autopsy—reveals some things, but not how the brain works in a living, functioning being. Assistant Professor of Chemical Engineering Mikhail Shapiro is determined to reveal the mysteries of the brain in situ, in living beings, right down to the cellular level.

Theodor Agapie Wins Presidential Early Career Award

Theodor Agapie, assistant professor of chemistry at the California Institute of Technology (Caltech), is a 2014 recipient of a Presidential Early Career Award for Scientists and Engineers (PECASE). Agapie will receive the award from President Barack Obama at a ceremony in the nation's capital later this year.

Probiotic Therapy Alleviates Autism-like Behaviors in Mice

"Traditional research has studied autism as a genetic disorder and a disorder of the brain, but our work shows that gut bacteria may contribute to ASD-like symptoms in ways that were previously unappreciated," says Sarkis Mazmanian.

Chemical Transformations for Food and Fuel: An Interview with Jonas Peters

"Our group is interested in the chemical transformations that are relevant to feeding and fueling the planet. There are two efforts on this campus in artificial photosynthesis, and I participate in both."

SlipChip Counts Molecules with Chemistry and a Cell Phone

In developing nations, rural areas, and even one's own home, limited access to expensive equipment and trained medical professionals can impede the diagnosis and treatment of disease. Many qualitative tests that provide a simple "yes" or "no" answer (like an at-home pregnancy test) have been optimized for use in these resource-limited settings. But few quantitative tests—those able to measure the precise concentration of biomolecules, not just their presence or absence—can be done outside of a laboratory or clinical setting.

Caltech Names Thomas F. Rosenbaum as New President

Today Caltech announced the appointment of Thomas F. Rosenbaum as the Institute's ninth president. Dr. Rosenbaum is currently the John T. Wilson Distinguished Service Professor of Physics and provost at the University of Chicago.

Caltech Nobelist Zewail Named to UN Scientific Advisory Board

Ahmed Zewail, Linus Pauling Professor of Chemistry and professor of physics, has been selected as one of 26 members of a new U.N. Scientific Advisory Board.

Caltech Researchers Synthesize Catalyst Important In Nitrogen Fixation

The industrial technique used to make nitrogen fertilizers mirrors the natural process of nitrogen fixation but requires high heat and pressure. Researchers at Caltech have synthesized a catalyst that allows for nitrogen fixation under much milder conditions.
