To stop bleeding, apply pressure—with tiny sponges. A group of veterans, scientists, and engineers in Oregon have a developed a device that uses small medical sponges to stop bleeding from gunshot wounds in just 15 seconds.
It hasn't been all that easy to make your own touchscreen-friendly gloves short of grabbing a needle and some conductive thread. With Tony Yu's upcoming Nanotips, however, it could be as simple as applying touch-up paint. The conductive liquid gives any pair of gloves (and many other surfaces) the same capacitive effect as your own fingers, letting you use your phone no matter what style of handwear you prefer -- you can check email while you're still dressed for a motorcycle ride. If you're intrigued by the idea, you can pledge $22 Canadian ($20 US) to get a bottle of Nanotips Black, which is intended for rubber and other thicker materials. Outside of early bird specials, it costs $30 CAD ($27 US) to get the fabric-oriented Nanotips Blue. Both formulas should reach backers between February and March.
Globalstar's Sat-Fi won't be the only game in town for satellite hotspots. Iridium has unveiled the Iridium Go, a hotspot that lets up to five WiFi-equipped devices hop on the internet, send texts and make phone calls from just about anywhere on the planet. It's built for outdoor adventurers with both a rugged design and an SOS mode that gets in touch with emergency services. However, software may be the Go's real ace in the hole; while it will ship with official Android and iOS apps, there's already a developer kit that lets third-party software take advantage of the satellite link on any platform. Iridium plans to ship the hotspot in the first half of the year. The firm isn't discussing exact pricing at this point, but it promises that Go will represent its "lowest cost" offering to date at below $800 -- for some people, it will be cheap enough to come along on that big summer hiking trip.
The White House won't be going it alone as it brings US classrooms into the internet era through its ConnectED initiative -- it just revealed that a host of technology firms will also lend a hand. Apple plans to donate $100 million in iPads, MacBooks and software to underprivileged schools, while Autodesk and O'Reilly Media will give away free software and content. Microsoft, in turn, will heavily discount Windows to lower educational PC prices. Carriers are getting in on the action, too. AT&T and Sprint have both pledged to offer free wireless broadband to schools for multiple years; Verizon ! isn't giving away service, but it will donate up to $100 million in cash and other commitments. The combined efforts aren't going to fix the American education system by themselves, but they could create a level playing field for schools across the country.

We've talked about why you should have more than one cooking oil in your kitchen
One of the biggest reasons you'd want multiple oils in your kitchen, especially more than just olive oil, is because different oils smoke at different temperatures, which means they lend themselves—and their flavor—best to different cooking methods. For example, ghee (clarified butter) or avocado oil both have high smoke points (well over 500 degrees F) so they're great for high-heat cooking, frying, and broiling in ways that sesame or pumpkin oil, which have lower smoke points (closer to 300 or 400 degrees F, respectively,) are not. Similarly, the chart shows you which types of oil are best applied in which types of cooking, regardless of their smoke points. For example, it notes that coconut oil is great for baking, sauteing, and frying, while your extra virgin olive oil and sesame oil may be better off used in dressings and to add extra flavor.
