Better Learning Through (Pen-and-Paper) Technology
‘This particular outcome suggests that contrary to popular belief, “laptops may be doing more harm in classrooms than good” by creating poor habits that are hard to break.
‘Researchers Pam Mueller and Daniel Oppenheimer asked college students to watch a series of TED Talks videos and take notes using either pen and paper or a laptop that was not connected to the Internet. They then quizzed the students on their understanding of the videos. The results, which were published in Psychological Science, showed that those who used the laptop for note-taking “consistently did worse at answering conceptual questions, and also factual-based ones when there was a considerable delay between the videos and testing.”…’

‘If you’re in search of a better way to figure out the molecular makeup up your food, then you might be interested in SCiO, a handheld molecular analyzer that pairs with your smartphone and costs just $149. Developed by Consumer Physics, the company is offering a much more user-friendly option than the spectrometers found in labs that normally cost thousands of dollars.
‘The device, which is not much bigger than a keyring, works by shining a blue light onto an object you want to analyze. SCiO’s partner app will then take the spectrometer reading, upload it the company’s servers, analyze and compare it to known spectral signatures, before returning as easy-to-understand information…’
Liquid Metal Used to Reconnect Severed Nerves
Remember T-1000, the nemesis of Terminator in Terminator 2? He’s starting to get real too
‘Today, Jing Liu at Tsinghua University in Beijing and a few pals say they’ve reconnected severed nerves using liquid metal for the first time. And they say that in conducting electrical signals between the severed ends of a nerve, the metal dramatically outperforms the standard saline electrolyte used to preserve the electrical properties of living tissue.
‘Biomedical engineers have been eyeing the liquid metal alloy gallium-indium-selenium for some time (67 percent Ga, 20.5 percent In and 12.5 percent Se by volume). This material is liquid at body temperature and is thought to be entirely benign. Consequently, they have been studying various ways of using it inside the body, such as for imaging…’
Another Evil Genius from Facebook?
‘It is best to put quotes around “anonymous login,” for “anonymous login” is not truly anonymous. It’s simply a complement to the “login with Facebook” button you see at signup on all manner of third-party apps and services. The app or service won’t receive any information about you — but Facebook still verifies it’s you, and gets the skinny on what it is you’re doing, what app you’re logging into this time, and how often you’ve logged into that app, which it gets to combine with all the other data it has on you. It’s as anonymous as a two-way mirror.
‘This is a brilliant business move in many ways, and I wouldn’t have been surprised to hear Zuckerberg do his best evil-genius laugh on stage at f8…’
