    • Welcome to Just Show Me on Tecca TV, where we show you tips and tricks for getting the most out of the gadgets in your life. In today's episode we'll show you how to turn off in-app purchases on your iPhone.

      Some apps let you buy things to enhance their functionality right from the app. For instance, a game might let you buy some in-game power ups or more farms to sow your oats on. These in-app purchases can be expensive, and you might not want people to be able to buy them, especially if you've got young children. Restricting in-app purchases is easy, and we'll walk you through it step by step.

    • If you're willing to spend the next 4 months eating space food for profit, this opportunity is for you

      Was your favorite part about a visit to the Air and Space Museum the little packets of space ice cream they sell at the gift shop? If so, you'll be glad to know that scientists are preparing to create a new generation of space desserts — and is seeking the public's help to do it.

      The study, being run by jointly run by Cornell University and the University of Hawaii, seeks to simulate a 4-month mission to Mars — or at least, the eating part of the mission. Six lucky "crewmembers" will wear space suits, live in a small Mars-like habitat, and consume nothing but instant space foods for a period of 4 months.

      Though the entirety of the study will take place here on Earth, the study is seeking those with NASA-level qualifications. Namely, participants should have a bachelors in the sciences, professional experience, the ability to pass a physical examination, and a history of conducting field research. You will also need to have a normal sense of taste and smell — smokers need not apply.

    • If you're like me, your vision of the future involves lots and lots of home robotsMechanical friends who bring me a warm cup of coffee in the morning, and a warm cup of Irish coffee at night. Thanks to Hitachi corporation, that future may be here sooner than we think.

      The EMIEW 2 robot is an adorable, child-like android that's connected to the internet. It uses built-in cameras to map its surroundings and identify objects. When it has an image of an item it wants to identify, it takes to Google to run an analysis.

      When the robot is given added data from a series of video cameras mounted around the office, it's able to quickly show you where you absent-mindedly put down your pencil. That's all well and good until a robot wearing a security uniform starts asking you about the office supplies you're trying to smuggle out in your coat pocket. Sneaky little things, these omniscient robots are.

    • Its manufacturer says it's safe, but the government is investigating

      It's called AeroShot, a tiny little 0.01-ounce container filled with caffeine, vitamins, and a hint of flavoring. Its manufacturer markets it as a dry energy shot. But is it dangerous? That's exactly what Senator Chuck Schumer (D-NY) and the Food and Drug Administration want to know.

      AeroShot was designed by Harvard professor David Edwards, a doctor who adapted his work on inhaled insulin and vaccines to the energy drink market. The product lets customers trade in foul-tasting energy drinks for an (ideally) less-foul tasting caffeine powder.

      When used as directed, the powder doesn't go into your lungs — it's designed to dissolve harmlessly on your tongue. Because of this, its parent company Breathable Foods believes that the AeroShot will pass government muster. But because the product has appeal to kids and teens, and because it could potentially be abused, the FDA wants to take a closer look.

      "We need to make sure that AeroShot does not become the next Four Loko by facilitating

    • $0 buys you a whole lot more phone than it used to

      Smartphones are here to stay, and it's no surprise why. They connect us to Facebook, help us find directions to the office, take pictures, and can even let us connect our laptops to the internet from the side of the road. But they're just so darned expensive... or so you think.

      You don't need to spend $300 or more just to get a great phone. We've put together a list of six great free smartphone options — they won't cost you anything but your signature (and, of course, a new contract). These phones aren't one-day-only deals, and they aren't refurbished models that someone's already had their fingerprints all over. They're absolutely free, absolutely new phones.

      You don't need to know somebody who knows somebody to get these phones for free, but you do need to buy these online. Most carriers have special, online-only pricing. And if you're upgrading an old phone, be careful. Some carriers will charge you an upgrade fee if you're still under an old contract. What fun is a free phone if
