Mars Gullies Likely Not Formed by Liquid Water

Martian gullies as seen in the top image from HiRISE on NASA's Mars Reconnaissance Orbiter resemble gullies on Earth that are carved by liquid water. Image credit: NASA/JPL-Caltech/UA/JHUAPL New findings using data from NASA’s Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian…

Chorus of Black Holes Sings in X-Rays Announced by Caltech Investigator

The blue dots in this field of galaxies, known as the COSMOS field, show galaxies that contain supermassive black holes emitting high-energy X-rays. Credits: NASA/JPL-Caltech Supermassive black holes in the universe are like a raucous…

Dave Asprey, Founder and CEO of Bulletproof Biohacker, bestselling author, and Bulletproof® Coffee CEO Dave Asprey today announced that the highly anticipated fourth annual Bulletproof Biohacking Conference will be held September 23 to 25, 2016…

Caltech Scientists Improve Computer Graphics with Quantum Mechanics

The Schrodinger equation, the basic description of quantum mechanical behavior, can be used to describe the motion of superfluids—fluids, supercooled to temperatures near absolute zero, that behave as though they are without viscosity. Schroder and…

JPL Sails Full-Speed Ahead in Solar System Exploration, Seeks Answer to “Are We Alone?”

Montage of planets. Image credit: NASA/JPL NASA’s Juno is now poised to shine a spotlight on the origins and interior structure of the largest planet in our solar system. As the world awaits Juno’s first close-up images of Jupiter (to be taken Aug. 27 during the spacecraft’s next pass by the planet), NASA and JPL continue to explore our solar system to help answer fundamental questions about how we came to be, where we are going and whether we are alone in the universe. “Juno is the latest example of the extraordinary science we have to look forward to right in our…
