Use the Valsalva Maneuver to Prevent Ear Pain When Flying [Flying]

Use the Valsalva Maneuver to Prevent Ear Pain When FlyingEar-popping pain is one of the hazards of flying. For some, especially kids or those with colds, Pain In The Ear or Airplane Ear can be quite severe. Mun Fitness Blog suggests several tips for preventing this condition, including the "Valsalva maneuver."

In the Valsalva manuever, you close your mouth and pinch your nose shut and exhale forcibly through your nostrils. You'll hear a "popping" sound and the pressure should be equalized in your ears. (Unequal pressure in your ears when the plane takes off or lands is the cause of Airplane Ear.)

Besides several other suggestions for preventing ear pain when flying, Mun Fitness Blog also offers a great tip for preventing ear pain that happens when driving:

Ear pain also happens while sitting in a car which come down from a steep mountain quickly with the window rolled up. Leave a crack in the window when descending or climbing a steep mountain will help.

I've always just chewed gum when flying. What's your strategy?

Hack a TV Remote to Control Your Computer's Audio [DIY]

Hack a TV Remote to Control Your Computer's AudioIf you use your computer for playing music, chances are at least once you've wished you had a remote control for it. Hacker Owen Trueblood wanted the same thing, so he hacked a TV remote to work with an infrared sensor attached to his computer.

Using an old TV remote, an ATtiny13 microcontroller, and an infrared receiver pulled out of an old VCR, he was able to set up the remote to control the computer's volume by hacking the IR sensor into a USB. Seeing as how most computers don't come with a remote, this is handy if you're using a computer specifically for music playing all day long. You can find the full guide, including the source code for the control app on the computer over on Hackniac.

TweetDeck Releases New Native Client for Windows and OS X, Isn't Quite as Feature-Filled as the AIR Version [TweetDeck]

TweetDeck Releases New Native Client for Windows and OS X, Isn't Quite as Feature-Filled as the AIR VersionWindows/Mac: A brand new version of TweetDeck is out that ditches Adobe AIR and brings its customizable columns to native Windows and Mac apps—though it's a bit more basic than the old version.

Twitter is going through a major interface change, but TweetDeck users may not have realized that our favorite Twitter client is doing the same—likely to keep up with Twitter's overhaul, since Twitter now owns TweetDeck. TweetDeck released this update pretty silently—no word on their blog, and your current copy of TweetDeck won't notify you of the update because its an entirely new application. As such, we didn't even realize it happened for a few days—but you can head to TweetDeck.com right now to download the new client.

The new client fixes a lot of the weird behavior caused by AIR in the old client. Everything feels a bit smoother, especially the scrolling. However, it's also missing a lot of the features that made the AIR client great, like keyboard shortcuts, color palette customizations, and lots of the other little settings that let you customize how you view Twitter. Hopefully these will come back soon, but TweetDeck has stayed pretty quiet about the entire rollout. Luckily, a lot of the things that make TweetDeck great—like a customizable column interface—are still there, and you can download the new client and try it out without uninstalling the AIR version you already have—they're two completely separate programs. So hit the link below, give the new client a whirl, and let us know what you think in the comments.

TweetDeck is a free download for Windows and Mac OS X.

Creative Thinking Is a Specific Process That Can Be Replicated [Creativity]

Creative Thinking Is a Specific Process That Can Be ReplicatedWe tend to look at creativity as a wild force that often eludes us but we can sometimes grasp and use to create amazing things. Tony Schwartz, president of The Energy Project, believes that when we're thinking creatively it's the result of a series of events, and when we know that series we can replicate it and think creatively whenever desired.

Schwartz outlines the following four steps as necessary in the creative thinking process, jumping from the left brain to the right and back again:

Saturation: Once you know the creative task at hand, immerse yourself in similar work created by the masters and study it.Incubation: Walk away from the task and let it sit in your head for awhile so the right hemisphere of the brain can process the thoughts creatively.Illumination: Do something to break up your day. If you're at your desk, step away and go somewhere else. You likely get your best ideas away from your usual surroundings so put yourself in a new situation to let that "aha!" moment surface.Verification: Test your inspiration and create.

These steps are designed to immerse you in creative work and keep you from sitting at your desk, waiting for an idea to surface. Perhaps the most important thing to remember is this: creativity doesn't come from stagnation, so keep your mind moving and it'll yield better results.

How do you think creatively? Do you have a specific process that works for you? Let us know in the comments.

A Cup of Coffee Before Exercise May Make You More Motivated to Go the Distance [Health]

A Cup of Coffee Before Exercise May Make You More Motivated to Go the Distance Everyone knows a cup of coffee can make you more alert and feel energized, but researchers from Coventry University in the UK think they've uncovered a solid, scientific reason why a little caffeine before your workout may be beneficial. The scientists conducted a small study, and observed that participants who enjoyed a caffeinated drink hung in on their workout much longer than participants who drank the same drink, only caffeine-free.

The Coventry University study was very small—only about 13 athletes—and it only serves as a gateway to additional research. Even so, it does point to a conclusion that many of us have known for a while—that a little caffeine helps us stick out tough situations a little longer, and stay alert when we would have otherwise started to tire. The researchers point to the fact that since it was removed from the list of banned substances by the World Anti-Doping Agency, a study involving over 20,000 Olympic athletes shows that caffeine was their new drug of choice.

The mechanisms behind how caffeine motivates people to exercise longer and harder are still poorly understood, but researchers think that caffeine may reduce the buildup of adenosine in a person's muscles. Adenosine is the chemical responsible for making it more difficult for our muscles to exert force, and makes us feel fatigued when we keep pushing ourselves when we exercise. Whether the study results will pan out for lighter aerobic exercise remains to be seen, and researchers say they're not clear on how much caffeine is required to get the desired effect in an average person, but early results from this and other studies involving caffeine and athletes are all promising.

For the time being, it definitely can't hurt to have your morning cup of coffee before you hit the treadmill—you never know, you might stay on a bit longer. Just make sure to stay hydrated while you work out. Do you have your morning cup before you work out, or rely on a caffeinated drink to keep your energy up when you exercise?
