This Week In Science: Rosetta Touches Down, Thought Control Made Easy, and Why You Cry When You’re Happy
Seven days; lots of science in the news. Here’s our roundup of this week’s most notable and quotable items:

Rosetta mission scientists succeeded in landing the Philae probe on Comet 67P/Churyumov-Gerasimenko, although a slightly rough landing left the lander tilted and its long-term hold on the comet in doubt. More and more studies are investigating the connection between gut bacteria and mental health. But a lot of research into our microbiome–the collection of bacteria and viruses living in our bodies–may be heavily skewed by contamination in lab equipment. Jupiter’s Great Red Spot might be a planetary form of sunburn.
Scientists made a device that allowed human participants to turn on genes in mice with their brainwaves. Using robotic underwater gliders, researchers figured out that Antarctic glaciers are melting from the bottom up. Promiscuity among females in some mammal species may be a defense against infanticide. “Bio-drones” made mostly of fungus and bacteria are in development; if they crash, they biodegrade and leave almost no trace behind.
