More than a year after the 2025 Los Angeles fires, Caltech labs are pressing forward with research projects to provide answers in service of public health and safety. Through investigations such as testing for heavy metal contamination, monitoring air quality,... More »
The rise of automation and AI has raised fears about job loss, but a team led by Caltech medical engineers suggests that smart tools can help train and assist workers rather than replace them. The team has developed a low-cost device that trains and assists pe... More »
Before the Omicron variant appeared in nasal swabs and PCR results, it was already flowing through the sewers — and Smruthi Karthikeyan found it there. Karthikeyan, a Caltech assistant professor whose wastewater surveillance work helped detect emerging COVID-... More »
The Nancy Grace Roman Space Telescope is at Kennedy Space Center in Florida right now, being prepped for an August 30 launch. Five weeks before liftoff, Lee Armus will try to explain what it can do — in 30 minutes, to anyone who walks through the door. Armus, ... More »
For years, Andy Klesh’s students have gone through a dress rehearsal for what it takes to design and then send a project to space. His course, Practical Electronics for Space Applications, is taught every two years and has typically used balloons to loft stud... More »
Researchers at Caltech in Pasadena have reported that people making risky decisions with another person often move toward compromise, but those who claim more credit for successful outcomes and less blame for failures tend to compromise less with their partner... More »
Four in 10 patients walked into their primary care doctor’s office carrying a hidden marker of heart failure that no one had detected. A five-minute test, built on technology that began in a Caltech laboratory, caught what standard screening had not. Those are... More »
Each year, the National Science Foundation (NSF) selects students to receive Graduate Research Fellowships that fund three years of graduate study in master’s or doctoral programs including research in science or engineering. This year, 34 Caltech alumni and 1... More »
Five new study topics have been selected by the Keck Institute for Space Studies (KISS) at Caltech to develop collaborations, frameworks, and mission concepts to transform the future of space exploration. The projects were competitively selected as part of KIS... More »
With the recent growth of AI, particularly with widespread adoption of large language models (LLMs) such as ChatGPT, there has been a dramatic increase in the need for data centers—facilities that house the computers and data storage systems that make the tech... More »
Every June, the hallways at NASA’s Jet Propulsion Laboratory fill with new badges. The names change, but the pattern does not: hundreds of undergraduate and graduate students arrive to spend 10 weeks working alongside the engineers and scientists who build and... More »
Since the early 2000s, lithium-ion (Li-ion) batteries have become the predominant rechargeable power source for many mobile devices, electric vehicles, renewable-energy storage grids, and more. But the Li-ion batteries in commercial use carry both safety risks... More »
