Astronauts Christopher Cassidy and Luca Parmitano returned to the International Space Station’s Quest airlock Tuesday, closed the hatch and repressurized the compartment to bring a planned 6.5-hour spacewalk to an early-but-safe conclusion, after an unusual and potentially dangerous buildup of water in Parmitano’s helmet.

* A federal judge has dismissed a class-action lawsuit against Instagram over controversial terms-of-service changes announced last year that many feared awarded ownership of users’ photos to the popular photo-sharing service.

* Global positioning systems can be hard enough to use on a clear, sunny day. But when it rains, or a storm hits, the satellite signals tend to go haywire. While it’s a huge inconvenience for drivers and pilots, NASA and National Oceanic and Atmospheric Administration (NOAA) are now using the GPS mayhem to better predict the ferocity of hurricane and tropical cyclone winds.

* The fearsome bite of a hungry Tyrannosaurus rex left behind new evidence that the famous beast hunted for food and wasn’t just a scavenger. Researchers found a part of a T. rex tooth wedged between two tailbones of a duckbill dinosaur unearthed in northwestern South Dakota.

* Yahoo CEO Marissa Mayer gets a B for trying something different: a live video stream of Yahoo’s second quarter earnings. She still gets a gentlewoman’s C for what remained another uninspiring earnings report. After a year at the helm, Mayer still has a lot of work ahead before she can declare mission accomplished. In the meantime, she made the show interesting with a certain style, even when that style was at times, well, odd. Think Hans & Franz, but without the yuks.
