A 3D-printed titanium spring designed and built at NASA’s Jet Propulsion Laboratory in Pasadena was deployed in orbit aboard a commercial satellite, demonstrating that ‘additive manufacturing’ can reduce the cost and complexity of spacecraft hardware, the agen... More »
Caltech scientists have developed a method that detects tiny, imperceptible movements at the surface of objects to reveal details about what lies beneath. By analyzing the physics of waves traveling across the surface of an object—whether that be a manufacture... More »
Hundreds of Pasadena Unified School District students will compete in hands-on science and engineering challenges Saturday morning at John Muir High School, and by noon the same campus will open to the broader community for a free festival featuring exhibits f... More »
An asteroid roughly the size of an airplane passed safely by Earth on Sunday, tracked from start to finish by scientists at NASA’s Jet Propulsion Laboratory in Pasadena. The space rock, designated 2026 CN3, came within approximately 2.05 million miles of Earth... More »
Caltech and Cedars-Sinai Health Sciences University announced a formal partnership this month that will create joint research grants, shared faculty and student appointments, and co-hosted scientific symposia between the Pasadena university and the Los Angeles... More »
Some of Pasadena’s most prominent research institutions — Carnegie Observatories, Caltech, and NASA’s Jet Propulsion Laboratory — will set up exhibitions for K-12 students and their families at the annual PUSD Science Fest on Saturday, March 7, at John Muir Hi... More »
The lithium-ion battery is everywhere — in the phone in your pocket, the laptop on your desk, the electric car in your neighbor’s driveway. But the chemistry that makes it work depends on minerals that are expensive, difficult to extract, and finite. Kimberly... More »
The planets in our solar system grew out of a disk of material that swirled around our Sun. Inner rocky planets formed as tiny grains stuck together, becoming pebbles, then boulders, and, ultimately, full-grown planets. The outer gas and ice giant planets also... More »
Right now, molecules in the air are moving around you in chaotic and unpredictable ways. To make sense of such systems, physicists use a law known as the Boltzmann distribution, which, rather than describe exactly where each particle is, describes the chance o... More »
Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the way for a new generation of ultra-coherent and efficient photonic integrated c... More »
A technology pioneered at NASA’s Jet Propulsion Laboratory in Pasadena is showing promise as a tool for tracking plastic pollution in the world’s oceans, though scientists caution that significant challenges remain before space-based sensors can reliably detec... More »
The power of artificial intelligence (AI) and advanced computing has made it possible to design genetic sequences encoding for diverse biological applications, such as proteins that form the building blocks of materials stronger than steel, or personalized can... More »
