Relief for Couch Potatoes, Canine Contraceptives and One Charmingly Alarming Solution

Losing the remote is so last year with the new device that detects hand movements to control a television. Australian researchers have developed a box that can recognize seven different hand motions, from the thumbs up to an outstretched hand, to signal different commands for a television, DVD player or video recorder. The device supposedly works in any light and from a range of distances. Once the researchers get the box small enough to fit on a television, we'll finally be able to watch TV without all that hassle of actually lifting up a remote.

The iMartha

All those style-blind guys out there trying to match ties and shirts have help on the way. HP has announced a research project that would allow people to use their camera-phone to match colors. After sending a picture of themselves or an object they want to match, users will receive a text message a few minutes later with color recommendations. The pictures are processed and analyzed pixel-by-pixel for color value, erasing the effects of bad lighting. HP officials say the new tool will help women trying to buy makeup, but I can guarantee I'll use it almost every day to figure out what color shirt I should wear with my jeans.

Insert Tiger Woods pun here
caddyshack12.jpgMembership at your country club might get a little less exclusive if a team of American scientists has their way. They're advocating that golf courses be used as animal sanctuaries, since 70 percent of the well-manicured land isn't even used for playing. The greens are ideal places for animals, since they can be altered to mimic natural habitats and would be protected. On the other hand, this idea opens the door to all kinds of Caddyshack gopher-style animal hijinx.

Snow in Buenos Aires?!
I'll admit, after living my entire life up north where winters are cold and snow is common, I can't empathize with people who joyfully greet every flurry by trying to have a snowball fight. But even my heart was warmed by the story of Buenos Aires getting its first taste of snow in almost 90 years. There have been cold temperatures plaguing Argentina since May, but a moisture-laden system moving in caused the snowfall on Argentina's Independence Day, the city's first since 1918. Sure, the story is dampened by the 23 deaths from exposure to cold, the energy crisis that has hit the country in light of the cool temperatures and the knowledge that this is just more evidence of how screwy our weather system has become, but the thought of Argentine children making snow angels is too much to not be happy.

nasal spray.jpgBoost Your Confidence, Via Nose
We've all been told that the best way to get over a fear of public speaking is to imagine everyone in their underwear. Apparently, the second-best way is a confidence-boosting nasal spray. Australian researchers developed the spray, which releases oxytocin into the bloodstream. In tests of 70 men and women, the drug was shown to reduce shyness in stressful social situations. Following large-scale tests, the spray should be commercially available in five years, so shy guys will finally have the courage to talk to girls at the bar after putting a little something up their nose. Sounds like a totally novel idea that will do great in the 1980s.

Neuter no more
Until now, dog birth control has been pretty one-sided; it's either neuter or nothing. But now an Australian company has unveiled a contraceptive implant for use in male dogs that will curb testosterone for months at a time, leaving a less permanent and relatively more comfortable alternative. The implant controls the hormone linked to testosterone production, not only killing the dog's sex drive, but also relaxing his aggressive behavior. Dogs aren't quite out of the water yet; the company still urges neutering as the best option if the owners don't want any breeding.

Picture 13.pngIsn't it time you gave her a ring?
Don't worry, I'm not talking about proposing. Since I reward myself for enduring the obnoxious buzz of my alarm clock with five more minutes of sleep, I think I might be in line for this sleek alarm from Yanko Design. The alarm is actually a ring that can be programmed to vibrate at a certain time. The vibrations of the ring then awake you in a manner slightly less jarring than the blaring horn of most clocks. This innovative alarm is especially useful for the hearing-impaired and couples waking up at different times.

Why a Howling Wind Sounds So Spooky, According to Science

Halloween is swiftly approaching, meaning you'll likely soon hear creepy soundtracks—replete with screams, clanking chains, and howling winds—blaring from haunted houses and home displays. While the sound of human suffering is frightful for obvious reasons, what is it, exactly, about a brisk fall gust that sends shivers up our spines? In horror movie scenes and ghost stories, these spooky gales are always presented as blowing through dead trees. Do bare branches actually make the natural wailing noises louder, or is this detail added simply for atmospheric purposes?

As the SciShow's Hank Green explains in the video below, wind howls because it curves around obstacles like trees or buildings. When fast-moving air goes around, say, a tree, it splits up as it whips past, before coming back together on the other side. Due to factors such as natural randomness, air speed, and the tree's surface, one side's wind is going to be slightly stronger when the two currents rejoin, pushing the other side's gust out of the way. The two continue to interact back-and-forth in what could be likened to an invisible wrestling match, as high-pressure airwaves and whirlpools mix together and vibrate the air. If the wind is fast enough, this phenomenon will produce the eerie noise we've all come to recognize in horror films.

Leafy trees "will absorb some of the vibrations in the air and dull the sound, but without leaves—like if it's the middle of the winter or the entire forest is dead—the howling will travel a lot farther," Green explains. That's why a dead forest on a windy night sounds so much like the undead.

SpaceX's Landing Blooper Reel Shows That Even Rocket Scientists Make Mistakes

On March 30, 2017, SpaceX did something no space program had done before: They relaunched an orbital class rocket from Earth that had successfully achieved lift-off just a year earlier. It wasn't the first time Elon Musk's company broke new ground: In December 2015, it nailed the landing on a reusable rocket—the first time that had been done—and five months later landed a rocket on a droneship in the middle of the ocean, which was also unprecedented. These feats marked significant moments in the history of space travel, but they were just a few of the steps in the long, messy journey to achieve them. In SpaceX's new blooper reel, spotted by Ars Technica, you can see just some of the many failures the company has had along the way.

The video demonstrates that failure is an important part of the scientific process. Of course when the science you're working in deals with launching and landing rockets, failure can be a lot more dramatic than it is in a lab. SpaceX has filmed their rockets blowing up in the air, disintegrating in the ocean, and smashing against landing pads, often because of something small like a radar glitch or lack of propellant.

While explosions—or "rapid unscheduled disassemblies," as the video calls them—are never ideal, some are preferable to others. The Falcon 9 explosion that shook buildings for miles last year, for instance, ended up destroying the $200 million Facebook satellite onboard. But even costly hiccups such as that one are important to future successes. As Musk once said, "If things are not failing, you are not innovating enough."
