Climbers, guides, Sherpas, and Nepali officials are divided on what's next for Everest season.
Sixteen Sherpas were killed in an April 18 avalanche in the deadliest single day on Everest, but there's a long history of fatalities on the mountain.

Two injured Sherpas recount the horrific avalanche on Mount Everest.
The March 2014 landslide in Oso, Washington, a month ago today, called attention to the lack of a national system to monitor landslide data. The U.S. government prepares hazard maps for other types of natural disasters like earthquakes and floods, but not for landslides. Even though they cause up to 2 billion dollars a year in damages nationwide, most data is collected at state level. NASA’s Global Landslide Catalog (GLC), which collects data from media reports and disaster databases, is the first attempt to survey rainfall-triggered landslides.

The Royal Observatory of Belgium invites proposals from potential Guest Investigators for the analysis of data from PROBA2's two solar observation instruments, SWAP and LYRA. Young post-docs and PhD students are particularly invited to apply, although proposals from more senior Guest Investigators are also encouraged.
Proposals in response to this Fifth Call for Guest Investigators must be received by 1 June 2014.
A pair of supermassive black holes in orbit around one another have been spotted by XMM-Newton. This is the first time such a pair have been seen in an ordinary galaxy. They were discovered because they ripped apart a star when the space observatory happened to be looking in their direction.
An image of a galaxy cluster taken by the NASA/ESA Hubble Space Telescope gives a remarkable cross-section of the Universe, showing objects at different distances and stages in cosmic history. They range from cosmic near neighbours to objects seen in the early years of the Universe. The 14-hour exposure shows objects around a billion times fainter than can be seen with the naked eye.
