Results from NASA's Kepler planet-hunting mission have indicated that the most common planets in the galaxy are super-Earths—those that are bigger than Earth but smaller than Neptune. We have no examples of these planets in our own solar system, so Heather Knutson, assistant professor of planetary science at Caltech, and her colleagues are using space telescopes to try to find out more about these worlds. They hope to shed some light on the processes of planet formation and evolution and to be able to say something about how common or rare our solar system is when compared to those found throughout the universe.

"The thing that makes this study really interesting is that we did our calculations before we ever did any experiments," says Rob Phillips, the Fred and Nancy Morris Professor of Biophysics and Biology at Caltech.

In the recent study the researchers found that beneficial gut bacteria were necessary for the development of innate immune cells—specialized types of white blood cells that serve as the body's first line of defense against invading pathogens.

Imagine that you pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects a bright, clear image onto a wall or a big screen. Such a technology may be on its way, thanks to a new light-bending silicon chip.

Erik Winfree, professor of computer science, computation and neutral systems, and bioengineering, explains, "I tend to think of cells as really small robots. Biology has programmed natural cells, but now engineers are starting to think about how we can program artificial cells."

Using a novel microfluidic technique, researchers at Caltech have shown that, rather than simply replenishing immune cells after they become depleted, blood stem cells sense danger signals directly and quickly produce new immune cells.

Methane, a key greenhouse gas, has more than doubled in volume in Earth's atmosphere since 1750. Its increase is believed to be a leading contributor to climate change.
