New Wearable Sensor Detects Even More Compounds in Human Sweat


A team of researchers from Caltech has unveiled a new wearable sensor that can detect in human sweat even minute levels of many common nutrients and biological compounds that can serve as indicators of human health. The sensor technology was developed in the lab of Wei Gao, Assistant Professor of Medical Engineering; Investigator, Heritage Medical Research Institute; Ronald and JoAnne Willens Scholar.

New Research "UNCOVERS" Hidden Objects in High Resolution


Imagine driving home after a long day at work. Suddenly, a car careens out of an obscured side street and turns right in front of you. Luckily, your autonomous car saw this vehicle long before it came within your line of sight and slowed to avoid a crash. This might seem like magic, but a novel technique developed in the laboratory of Changhuei Yang, Thomas G. Myers Professor of Electrical Engineering, Bioengineering, and Medical Engineering; Investigator, Heritage Medical Research Institute, could bring it closer to a reality. "We can see all the traffic on the crossroads with this method. This might help the cars to foresee the potential danger that one is not able to see directly." explains electrical engineering graduate student Ruizhi Cao. [Caltech story]

A Quantitative Snapshot of the Human Impact on the Planet


Caltech researchers have developed a database containing global data on how humans have impacted the planet. The Human Impacts Database is designed to be accessible to scientists, policymakers, and everyday citizens. "In my view, the root to understanding is numeracy: once you have the numbers, it becomes clear what the problems are, which things are significant, and which things are less so," says Rob Phillips, Fred and Nancy Morris Professor of Biophysics, Biology, and Physics.
