When it comes to space exploration, Don Gurnett has seen it all. He still vividly remembers seeing America's first attempt at a satellite launch, the Vanguard project, blew up on the launch pad from the comfort of his living room. When it comes time to talk of more modern cosmic endeavors, he will wax poetic about hydrocarbon rains falling into pools of methane on Titan. He's been there for everything, and he's not done yet.
The brief lull in the Atlantic Ocean's hurricane activity seems to have come to an end sooner than we'd hoped. A new tropical depression is brewing in the western Caribbean Sea, and it could threaten the United States this weekend and early next week. It's still too soon to know what effects the storm will have, but the threat exists for a potential hurricane to approach the Gulf Coast on Sunday or Monday.
Before the invention of cryo-electron microscopy, which won biochemists Jacques Dubochet, Joachim Frank and Richard Henderson the 2017 Nobel Prize in Chemistry on Wednesday, scientists had to stain or fix cells before they looked at them under an electron microscope.

Last week I splashed into an underground university pool with an Apple Watch Series 3. As the company's wearable has matured, Apple has marketed it more and more as a fitness device, one that's, thanks to a partnership with Nike, particularly well-suited as a running companion. But the Apple Watch also tackles something more dynamic and varied than your morning jog: exercise in the water.
It was 8:07 p.m. on a Friday night in Riverhead, Long Island, when the operators at an RCA Communications outpost picked up a signal that had never been heard before on Earth. A sharp, insistent beep sang out over short-wave radios, filling up our ears with the knowledge that humans had succeeded in sending something to the wispiest edge of our protective blanket of nitrogen, oxygen, and carbon dioxide.
The second scale-topping hurricane to make landfall in the past two weeks will tear through Puerto Rico and the Virgin Islands on Wednesday, bringing to a climax one of the most severe hurricane seasons in recent memory. On Monday evening, Hurricane Maria rapidly strengthened into a category five shortly before striking the small island of Dominica.
