NASA’s Mars Reconnaissance Orbiter (MRO) caught a glimpse of the agency’s retired InSight lander recently, documenting the accumulation of dust on the spacecraft’s solar panels. In the new image taken Oct. 23 by MRO’s High-Resolution Imaging Science Experiment... More »
In a purposeful convergence of science and art that bridges disciplines, three renowned innovators will gather to challenge conventional wisdom about failure’s role in breakthrough achievements. Today’s panel discussion “Scientists and Artists on Failure” at C... More »
? In the future, delivering therapeutic drugs exactly where they are needed within the body could be the task of miniature robots. Not little metal humanoid or even bio-mimicking robots; think instead of tiny bubble-like spheres. Such robots would have a long ... More »
With the growing adoption of large language models, such as OpenAI’s ChatGPT, the enormous environmental footprint of artificial intelligence, or AI, is increasingly in the news. This cost is often discussed in terms of electricity consumed, carbon released in... More »
When the vintage DC-8 airliner made one of its harrowing low passes over California’s Central Valley, things got a little bumpy for the undergraduates packed inside. It was often hot and stuffy inside the flying atmospheric chemistry laboratory, which NASA had... More »
The 25th Invention Challenge at NASA’s Jet Propulsion Laboratory in Southern California, which welcomed more than 200 students to compete using home-built devices, was pretty sweet this year. Literally. That’s because the challenge at the Friday, Dec. 6, compe... More »
Brain–machine interfaces (BMIs) have enabled a handful of test participants who are unable to move or speak to communicate simply by thinking. An implanted device picks up the neural signals associated with a particular thought and converts them into control s... More »
Most of us are familiar with the process of making budgetary decisions by committee. A group of people, each with their own preferences and goals and representing different interests, must decide among themselves how to allocate resources. Such committees are ... More »
In a discovery that could change how doctors treat digestive disorders, Caltech scientists have uncovered new details about how our nervous system controls our gut and other internal organs. The research team has shown that the body’s stress response system is... More »
Caltech researchers have developed a new method to study the earth’s structure deep beneath the surface, at the boundary between Earth’s brittle crust and the underlying mantle, a region called the Mohorovi?i? discontinuity—Moho for short. Like taking an ultra... More »
Scientists and engineers on campus and Lab wished NASA’s Europa Clipper mission a bon voyage on October 14 as it launched from Earth toward Jupiter’s frozen moon, Europa. Hidden beneath Europa’s icy crust is an ocean containing twice the amount of water as on ... More »
Caltech researchers from campus and JPL have collaborated to devise a method for coating lithium-ion battery cathodes with graphene, extending the life and performance of these widely used rechargeable batteries. These efforts have led to a promising discovery... More »
