Look up at the night sky and you'll see stars, sure. But you're also seeing planets—billions and billions of them. At least.
That's the conclusion of a new study by astronomers at the California Institute of Technology (Caltech) that provides yet more evidence that planetary systems are the cosmic norm. The team made their estimate while analyzing planets orbiting a star called Kepler-32—planets that are representative, they say, of the vast majority in the galaxy and thus serve as a perfect case study for understanding how most planets form.

Protein engineers at Caltech have tapped into a hidden talent of one of nature's most versatile catalysts. The enzyme cytochrome P450 is nature's premier oxidation catalyst—a protein that typically promotes reactions that add oxygen atoms to other chemicals. Now the Caltech researchers have engineered new versions of the enzyme, unlocking its ability to drive a completely different and synthetically useful reaction that does not take place in nature.

For over 25 years, Paul Sternberg has been studying worms—how they develop, why they sleep, and, more recently, how they communicate. Now, he has flipped the script a bit by taking a closer look at how predatory fungi may be tapping into worm conversations to gain clues about their whereabouts.

Caltech electrical engineers have developed inexpensive silicon microchips that generate and radiate terahertz (THz) waves. These high-frequency electromagnetic waves fall into a largely untapped region of the electromagnetic spectrum—between microwaves and far-infrared radiation—and can penetrate a host of materials without the ionizing damage of X-rays.
