A cloaking device that makes you appear completely invisible is still trapped in the realm of science fiction. But researchers at Duke University have successfully created a cloaking device that works with sound instead, making an object completely invisible to SONAR and other acoustic imaging techniques.

Forget about stealing your neighbor’s Wi-Fi to surf the internet. Using cheap everyday materials, researchers at Duke University’s Pratt School of Engineering have developed a remarkable device that can convert microwave signals, like those used to wirelessly transmit the internet, into usable electricity. So in the future, you might instead be able to use your neighbor’s Wi-Fi network to power your home.

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.
Are you reading this? Seriously, are you? Sure, we know you think you are, but what if you’re just a sub-feature of a complex computer program. A sprite, nothing more than the creation of software. The problem with this question is, how would you ever know? You wouldn’t, right? Well, not so fast there. Turns out, maybe there is a way to unravel the matrix (if there is one). It’ll come as no surprise, that this is one of the topics in this week’s collection of alternative stories. Think that’s all we got? Not even close. We’ll explore the truth behind cloning dinosaurs, as well a rare performance by singing mice — all before dinner. Or is it really dinner? This is alt-week.

Those goggles you see above aren’t for stylish looks while playing dodgeball — they’re the keys to a potentially important discovery about short-term memory. Duke University‘s Institute for Brain Sciences found that subjects playing catch with goggles simulating strobe lights were noticeably better at memorizing information during tests, even a full day after playtime was over. It’s not hard to see why: with a limited amount of time to see that incoming ball, participants had to more vividly remember brief scenes to stay on top of the game. We don’t yet know if there’s any kind of long-term boost, so don’t get your hopes up that strobe lights are the shortcuts to permanent photographic memory. Still, the findings suggest that frequent nightclubbers might be on to something… or, at least, have a better idea of where they left their keys the morning after.
