Picture a bundle of copper wires. Now imagine twisting them and striking them against a hard surface, over and over. Eventually the wires fray, and the current stops. That, a Pasadena neurologist told public-radio listeners on Aug. 25, is close to what repeate... More »
In computer simulations of The Big One—a large magnitude earthquake that may occur along the San Andreas Fault in California—seismic waves ripple from a magnitude 7.8 epicenter near the Salton Sea up into the Los Angeles Basin. For minutes in this simulation, ... More »
The telescope that lifted off and rose majestically over the Florida coast just after sunrise Sunday belongs to the whole country. A good deal of the work of running, it will happen in Pasadena. NASA’s Nancy Grace Roman Space Telescope lifted off at 4:26 a.m. ... More »
Free timed-entry tickets to Explore JPL, the two-day open house at the Jet Propulsion Laboratory, will be released at 9 a.m. on Saturday, Aug. 29. Tickets are expected to be fully reserved within 10 to 15 minutes, NASA estimates, based on the event’s popularit... More »
A new radio dish has risen from the Mojave Desert and begun catching signals from spacecraft scattered across the solar system — and the lab that runs it sits in Pasadena. The antenna, Deep Space Station 23, is a 34-meter-wide (114-foot) dish at NASA’s Goldsto... More »
Election rumors, such as unverified accounts of voter fraud, have run rampant in the US in recent years. Powered by the speed of social media and artificial intelligence (AI), it can be hard for people to know what messages to trust. Now, a team led by Caltech... More »
Building healthy habits now can help protect strength and independence later in life, according to guidance published this month by Huntington Health, the Pasadena hospital and Cedars-Sinai affiliate. In a blog post dated Aug. 14, the hospital summarized a dis... More »
NASA has selected Caltech to operate the Orbiting Carbon Observatory missions (OCO-2 and OCO-3) beginning this fall. OCO-2, a satellite, and OCO-3, an instrument on the International Space Station (ISS), both identify where carbon is being emitted and where na... More »
When different materials transition from one phase to another, such as water coming to a boil or a magnet losing its ability to attract metals, something remarkable can happen: They begin to behave identically, following the same mathematical rules. “Physicist... More »
Although increased cell proliferation is a hallmark of cancerous tissues, in some cases, it may actually be protective against tumor growth, according to a new study from Caltech researchers. Using mathematical models, the work suggests a new paradigm for the ... More »
For hundreds of students from Caltech and universities around the country, a summer internship at Jet Propulsion Laboratory offers more than a glimpse of science and engineering. It’s a chance to play an active role in discovery and exploration. This program h... More »
If you see a doctor regularly, chances are you have had a lipid panel ordered and your blood drawn at a lab. The results told your physician about your levels of cholesterol and triglycerides, factors that play a role in diagnosing conditions such as cardiovas... More »
