When Lakshmi first encountered pig's wings in a petri dish, she realized that writing about scientists and imagineers was the perfect way to live in an expanding mind bubble. Articles for Wired, BBC Online, New Scientist, The Economist and Fast Company soon followed. She's currently pursuing her dream of traveling from country to country to not only ferret out cool stories but also indulge outrageously in local street foods. When not working, you'll find her either buried nose deep in a fantasy novel or trying her hand at improvisational comedy.
What do you do after you've 3D-printed the world's tiniest functional power drill?
If you're Lance Abernethy, you go on to add another miniature power
tool to your Lilliputian toolbox. Abernethy's latest creation is a
working 3D-printed circular saw that fits in a briefcase slightly bigger
than a thumbnail.
Researchers at NASA's Jet Propulsion Laboratory have grown underwater chimney-like structures capable of generating enough electricity to power a light bulb. The team linked several of these chimneys to get the required electricity. Their findings indicate that the seafloor equivalents of these chemical gardens might just have contributed the electricity needed for the Earth's first organisms to develop.
A South Korean startup has created an active Braille smartwatch for the visually impaired that can be read by touch. Aptly named Dot, the wearable relays the time with a set of pins that rise and fall. Users will be able to receive and read text messages in real time, read e-books and even learn Braille.
Can you knock on your kitchen countertop to dim the lights, turn on your favorite music or send your partner a text message? You can if you have a "Knocki" stuck to it. Developed by Texas-based Swan Solutions, Knocki is a disc-shaped device that turns solid surfaces, such as walls, doors or tables, into remote control switches for internet-connected devices. All you have to do is knock.
Although we've seen "bio-inks" that allow sensors to be drawn directly on a person's skin and other surfaces to gauge things like glucose levels, functional inks such as this are usually heat-sensitive, meaning they aren't suitable for use in inkjet printers. Researchers at Tufts University have now developed silk-based inks containing bacteria-sensing agents that can withstand the rigors of inkjet printing, opening the door much wider for printing biomolecules.
