Researchers at MIT and the Max Planck Institute have developed a method for quick, on-site E. coli detection in food. While current food safety testing either requires days to complete or expensive equipment, this new method, paired with a smartphone and QR code, will make testing inexpensive and portable. The new detection process uses Janus emulsions, droplets consisting of two hemispheres of different densities. In water, the less dense, hydrocarbon hemisphere sits above the denser hemisphere

Accessible headphone jacks aren’t hard to find nowadays, but they’re always built into your average neighbourhood fixtures, like an ATM. This isn’t the most welcoming design since there’s no way to get the device as a standalone product. But the Canada Science and Technology Museum strives for inclusive design, and since they couldn’t buy an accessible headphone jack, their innovators decided to design their own.
