Quantum Information Meets Condensed Matter: Inside the Mind of Xie Chen

Xie Chen comes to Caltech after a two-year postdoctoral fellowship at UC Berkeley. Originally from China, Chen received her BS from Tsinghua University in Beijing and her PhD from MIT. She recently discussed with us her research interests and ambitions for her Caltech career.

The Birth and Death of Our Solar System: An Interview with Konstantin Batygin

Konstantin Batygin recently joined the Caltech faculty as assistant professor of planetary science, following graduate school at Caltech (PhD '12) and a postdoc at the Harvard-Smithsonian Center for Astrophysics. Batygin shares the string of synchronicities that brought him to planetary astrophysics and to Caltech.

Study of Aerosols Stands to Improve Climate Models

Researchers from Caltech and the Jet Propulsion Laboratory have provided a global observational study of the effect that changes in aerosol levels have on low-level marine clouds—the clouds that have the largest impact on the amount of incoming sunlight that Earth reflects back into space.

Biology Made Simpler With "Clear" Tissues

Thanks to new techniques developed at Caltech, scientists can now see through tissues, organs, and even an entire body, offering new insights into the cell-by-cell makeup of organisms—and the promise of novel diagnostic medical applications.

Looking Forward to 2020 . . . on Mars

Ken Farley, Caltech's W.M. Keck Foundation Professor of Geochemistry and chair of the Division of Geological and Planetary Sciences, is serving as project scientist for Mars 2020. We recently sat down with him to talk about the mission and his new role.

Sean Carroll Brings Physics to the Masses

Sean Carroll, a senior research associate in physics at Caltech, has won the 2014 Andrew Gemant Award from the American Institute of Physics.

Sink or Swim: Students Prep for RoboSub Competition

Students on the Caltech Robotics Team have created a robotic submarine that will compete in the 17th Annual International RoboSub Competition in San Diego.

New Division Chair for HSS

Jean-Laurent Rosenthal, the Rea A. and Lela G. Axline Professor of Business Economics, has been named the new chair of the Division of the Humanities and Social Sciences.

50 Years of Quarks

Caltech's Murray Gell-Mann simplified the world of particle physics in 1964 by standing it on its head. He theorized that protons—subatomic particles as solid as billiard balls and as stable as the universe—were actually cobbled together from bizarre entities, dubbed "quarks," whose properties are unlike anything seen in our world. Unlike protons, quarks cannot be separated from their fellows and studied in isolation; despite this, our understanding of the universe is built on their amply documented existence.
