MIT scientists have found a new use for Wi-fi: motion detectors. WiS is a low-powered Wi-Fi based system that works similarly to sonar and radar imaging.

WiZ is being developed at MIT by Dina Katabi, a professor in MIT’s Department of Electrical Engineering and Computer Science, and her graduate student Fadel Adib.  “We wanted to create a device that is low-power, portable and simple enough for anyone to use, to give people the ability to see through walls and closed doors,” said Katabi.

Vessyl: a smart cup that knows what you’re drinking

vessylVessyl is a smart cup that will tell you what you’re drinking in addition to what you’ve already had to drink. It’s a cup, but re-invented with computing technology and designed to perfection.

Vessyl is not your average smart device –  it’s a product that’s been seven years in the making, and it shows. From the handling of the lid to its display, this cup looks right when it’s working right. Once you’re done touching its faceted exterior and tilting the cup to read its screen, the lid slides open seamlessly to reveal its smart interior – capable of calculating liquid information into caloric, sugar, and molecular details. According to the Verge, who had access to the prototype, the Vessyl is so accurate, it “knows the difference between Gatorade Cool Blue and Glacier Freeze.” (more…)

Thirty years ago, the mortality statistics for expecting mothers in Bangladesh were grim. In 2002 things were not much better as the risk of dying from pregnancy in Bangladesh was 1 in 21, compared to 1 in 4,000 in industrialized countries. Ten years later, in 2012, pregnant mother mortality was down 68%, but still remained a public health concern. A new mobile app called Aponjon has now created a mobile app that reaches 100,000 soon-to-be mothers, dismissing common misconceptions, informing them of warning signs and directing them to local healthcare centers when needed.
