LUXURIOUS OVER-THE-EAR CANS  are plush, comfortable, and they sound great.  But  for working out, traveling, and wandering around town, you might want to consider a pair of durable, wireless in-ear buds. I've been trail running, hiking, working on my yard, lifting weights, and watching mildly embarrassing barre and yoga videos on my laptop, all while testing the best wireless workout headphones around. If you like listening to music while scrambling up stony slopes or mowing your lawn, here are a bunch of our favorite pairs. We've worn, and sweated on, all of them.

  Weirdo universe There's no questioning the fact that the universe is weird. Just look outside and you'll see all manner of strange, self-reproducing flora and fauna, crawling upon a blue ball of semimolten rock covered in a thin, hard shell and blanketed by a tenuous film of gases. Yet our own planet represents a tiny fraction of the peculiar phenomena that can be found lurking throughout the cosmos, and every day astronomers turn up new surprises. In this gallery, we take a look at some of the most outlandish objects in space. Mysterious Radio Signals (Image credit: NRAO Outreach/T. Jarrett (IPAC/Caltech); B. Saxton, NRAO/AUI/NSF) Since 2007, researchers have been receiving ultrastrong, ultrabright radio signals lasting only a few milliseconds. These enigmatic flashes have been called  fast radio bursts  (FRBs), and they appear to be coming from billions of light-years away (they're not aliens, it's never aliens). Recently, scientists managed to capture a repeating F
