"Blowing out a candle is so 2015," YouTube user Dianna Cowern jokes in the video below. Which is why the creator of Physics Girl found some considerably more interesting ways to extinguish a candle. In under six minutes, she runs down five unorthodox ways to put out a fire, from using a tight copper coil to blowing around a soccer ball. Watch Cowern break down the science of each method, and for more experiments, visit her YouTube page.
Giant squid have been the object of fascination for millennia; they may have even provided the origin for the legendary Nordic sea monsters known as the Kraken. But no one had captured them in their natural environment on video until 2012, when marine biologist and bioluminescence expert Edith Widder snagged the first-ever images off Japan's Ogasawara Islands [PDF]. Widder figured out that previous dives—which tended to bring down a ton of gear and bright lights—were scaring all the creatures away. (Slate compares it to "the equivalent of coming into a darkened theater and shining a spotlight at the audience.")
In this clip from BBC Earth Unplugged, Widder explains how the innovative camera-and-lure combo she devised, known as the Eye-in-the-Sea, finally accomplished the job by using red lights (which most deep-sea creatures can't see) and an electronic jellyfish (called the e-jelly) with a flashy light show just right to lure in predators like Architeuthis dux. "I've tried a bunch of different things over the years to try to be able to talk to the animals," Widder says in the video, "and with the e-jelly, I feel like I'm finally making some progress."
Medical dramas like Grey's Anatomy get a lot of things wrong when it comes to the procedures shown on the screen, but unless you're a doctor, you'd probably never notice.
For its latest installment, WIRED's Technique Critique video series—which previously blessed us with a dialect coach's critique of actors' onscreen accents—tackled the accuracy of medical scenes in movies and TV, bringing in Annie Onishi, a general surgery resident at Columbia University, to comment on emergency room and operating scenes from Pulp Fiction, House, Scrubs, and more.
While Onishi breaks down just how inaccurate these shows and movies can be, she makes it clear that Hollywood doesn't always get it wrong. Some shows, including Showtime's historical drama The Knick, garner praise from Onishi for being true-to-life with their medical jargon and operations. And when doctors discuss what music to play during surgery on Scrubs? That's "a tale as old as time in the O.R.," according to Onishi.
Other tropes are very obviously ridiculous, like slapping a patient during CPR and telling them to fight, which we see in a scene from The Abyss. "Rule number one of CPR is: never stop effective chest compressions in order to slap or yell words of encouragement at the patient," Onishi says. "Yelling at a patient or cheering them on has never brought them back to life." And obviously, taking selfies in the operating room in the middle of a grisly operation like the doctors on Grey's Anatomy do would get you fired in real life.
There are plenty of cliché words and phrases we hear over and over on doctor shows, and some are more accurate than others. Asking about a patient's vitals is authentic, according to Onishi, who says it's something doctors are always concerned with. However, yelling "We're losing him!" is simply for added TV drama. "I have never once heard that in my real life," Onishi says.
