Revenge thrillers benefit the most from a simple premise. A guy can lose the one thing he’s ever cared about — be it his girl, his dignity, or even his dog — and that’s typically enough to justify a few hours of visceral, nonstop mayhem. There’s naturally something to be said for the way these films depict brutality without blinking an eye, but the best actioners still tout a kind of catharsis you can’t find anywhere else.

Director Nikhil Nagesh Bhat understands all of the above, and his latest thriller, Kill, is a textbook example of revenge done right.

The film cherry picks tropes from Indian cinema and turns them on their head, delivering the kind of violence that can only be matched by something like John Wick or, more recently, Dev Patel’s Monkey Man. Fists and elbows crack down on bones, knives and machetes slash through skin and sinew, and an effortlessly cool hero delivers a masterclass in cruelty. Kill understands the assignment, even if it can rely a bit too heavily on formula: It’s a scrappy, one-location thriller that gets in and out in just over 100 minutes, and won’t fail to leave an impression.

Watch out, tardigrades: The first life form to colonize Mars may be a hardy desert moss, according to a recent study.

A team of researchers recently put a desert moss called Syntrichia caninervis through a barrage of tests, from years in a deep freeze to blasts of gamma and ultraviolet radiation, in a simulated version of Mars’s thin, mostly-carbon dioxide atmosphere. And the moss survived it all. According to the study, that means S. caninervis, also called steppe screw moss, may eventually be able to grow on Mars — and even help terraform the cold, dry planet.
