For people in developing nations or rural locations, getting clean water may soon be as simple as opening a book … and ripping a page out. That’s the idea behind The Drinkable Book, developed by Carnegie Mellon University postdoc Theresa Dankovich. Each of its pages is made from a thick sheet of paper impregnated with silver and copper nanoparticles, that kill 99.9 percent of microbes in tainted water that’s filtered through it.
Do you get itchy, cramped-up or wheezy from even a little bit of wine?
It could be because you have a sulfite sensitivity. Sulfites are
sulfur-based compounds that are added in the wine-making process to
prevent bacterial growth – they keep the wine from spoiling while it's
in transit and storage. Given that they're not needed once the wine has
been poured, however, chemist James Kornacki has developed a device for
reducing them at that point in the game – it's called the Üllo.
While a smoke detector can certainly provide you with an early warning
in the event of a house fire, it can't usually do much to help you get
out of the building once that fire is underway. That's why Toronto-based
startup Safety iQ developed the Saver. It's a portable device that
reportedly allows users to breathe safely in smoke-filled environments,
while also serving as a flashlight and alarm.
