Limited medical equipment on space craft makes medical care in space a real challenge. Ordinary problems must be dealt with, as well as problems related to the unique environment of space. As NASA plans for new crewed exploration missions, beyond low earth orbit, telemedicine support will be limited, and medical evacuation to earth will no longer be possible. To address this problem, LLNL and NASA Ames Research Center are developing a novel diagnostic instrument to help provide medical care on deep space missions. The technology consists of a blood analysis system, based on microfluidics, together with a breath analysis system that uses carbon nanotube sensors. The technology is designed to support future missions to the moon and Mars, and it is expected to be used for terrestrial medicine as well, in a variety of arenas where medical resources are limited.

The International System of Units (the SI), the modern metric system, has recently undergone its most revolutionary change since its origins during the French Revolution. The nature of this revolution is that all of the base units of the SI are now defined by fixing values of natural constants. Our measurement system is now, both philosophically and practically, strongly quantum. Nobel Prize recipient William Phillips, Ph.D., a Distinguished University and College Park Professor of Physics at the University of Maryland, talks about why this reform was needed and how it is done.

At the beginning of the 20th century, Einstein changed the way we think about time. Now, early in the 21st century, the measurement of time is being revolutionized by the ability to cool a gas of atoms to temperatures millions of times lower than any naturally occurring temperature in the universe. Nobel Prize recipient William Phillips, Ph.D., a Distinguished University and College Park Professor of Physics at the University of Maryland, talks about laser cooling and ultracold atoms and how they relate to time.
Data points, equations, and analysis are only part of a day in the life of a mathematician. UC San Diego's Alex Cloninger shares how he uses math to ask smarter questions, solve real world problems, and foster creativity. Series: "Education Channel" [Science] [Show ID: 37189]
With Amazon's Alexa spying on her owners, a massive data breach masterminded by Cambridge Analytica, and evidence of election interference promulgated by Facebook, tech policy has never had more significant implications for our society and democracy. Roger McNamee—noted tech venture capitalist, early mentor to Mark Zuckerberg, and Facebook investor—talks with Henry Brady, Dean of the Goldman School of Public Policy at UC Berkeley, about how he came to realize the serious damage that Facebook and other social media giants are doing and how he has committed to try to stop them.
