Caltech Geologists Discover Ancient Buried Canyon in South Tibet

A team of researchers has discovered an ancient, deep canyon buried along the Yarlung Tsangpo River in south Tibet. The geologists say that the ancient canyon—thousands of feet deep in places—effectively rules out a popular model used to explain how the massive and picturesque gorges of the Himalayas became so steep, so fast.

New Center Supports Data-Driven Research

The new Center for Data-Driven Discovery makes advanced computational tools available to researchers from all six Caltech divisions, plus JPL researchers.

Photosynthesis: A Planetary Revolution

Two and a half billion years ago, single-celled organisms called cyanobacteria harnessed sunlight to split water molecules, producing energy to power their cells and releasing oxygen into an atmosphere that had previously had none. These early environmental engineers are responsible for the life we see around us today, and much more besides. At 8:00 p.m. on Wednesday, November 19, in Caltech's Beckman Auditorium, Professor of Geobiology Woodward "Woody" Fischer will describe how they transformed the planet. Admission is free.

Converting Data Into Knowledge: An Interview with Yisong Yue

New faculty member Yisong Yue, assistant professor of computing and mathematical sciences, recently spoke with us about his research interests in machine learning and what he is looking forward to at Caltech.

Caltech and City of Hope Formalize Collaboration

Caltech and City of Hope have signed a memorandum of understanding, formalizing a relationship that encourages researchers from the two institutions to collaborate and share resources in the interest of furthering both basic scientific research and translational projects—those with a medical application. The memorandum establishes the Arthur D. Riggs Distinguished Lectureship series, which will bring scientists from across the country to speak at Caltech and City of Hope on current projects in basic research as well as on efforts to predict, prevent, diagnose, treat, and cure such diseases as cancer, diabetes, and HIV.

Heat Transfer Sets the Noise Floor for Ultrasensitive Electronics

A team of engineers and scientists has identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes and advanced physics experiments.

Robotic Ocean Gliders Aid Study of Melting Polar Ice

Caltech researchers use robotic ocean gliders to study how warm water is making its way to Antarctic ice sheets—and how this warming ultimately leads to rising ocean levels.

Making Hotter Engines and Lasting Artwork: An Interview with Katherine Faber

New faculty member Katherine Faber, the Simon Ramo Professor of Materials Science, studies the reasons why brittle ceramics fracture—and how these materials can be made stronger in the future.

Unexpected Findings Change the Picture of Sulfur on the Early Earth

Using a new analytical technique, Caltech researchers studying the rock record uncover new information about the sulfur cycle on early Earth and what that could mean for the rise of oxygen in the atmosphere.

Caltech Rocket Experiment Finds Surprising Cosmic Light

Using an experiment carried into space on a NASA suborbital rocket, astronomers at Caltech and their colleagues have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe.
