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.
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.
How to Grip an Asteroid
Caltech junior Edward Fouad spent 10 weeks this summer as part of the Summer Undergraduate Research Fellowship (SURF) program working in the lab of Aaron Parness, a group leader at JPL, where researchers are designing, prototyping, and refining technology for a device called a microspine gripper. Looking something like a robotic circular foot with many toes extending radially outward, such a gripper has the ability to grab onto a rocky surface and cling to it even when hanging upside down.

Voyager 1 Surfs a Cosmic Tsunami
The plasma wave instrument aboard Voyager I captured the sound of ionized gas vibrating in interstellar space three different times between November 2014 and December 2014. Physicist Ed Stone explains how the vibrations were caused by powerful blasts of solar particles, each resulting in a "cosmic tsunami."
