If you thought the time zones in your country were a big enough hassle, you’ll find the hodgepodge of time zones observed in Antarctica an outright mess.
Although logically Antartic, situated at the Earth’s southern pole, should have a bit of each longitudinally defined time zone in it. Instead, the scarcely population continent is a patchwork...
Computational Engineers at the University of Southampton have built a supercomputer from 64 Raspberry Pi computers and Lego.
The team, led by Professor Simon Cox, consisted of Richard Boardman, Andy Everett, Steven Johnston, Gereon Kaiping, Neil O'Brien, Mark Scott and Oz Parchment, along with Professor Cox's son James Cox (aged 6) who provided specialist support on Lego and system testing.
Bioengineers at Stanford University have turned living cells into data storage devices that can store a rewriteable small amount data, just like silicon devices. Sections of DNA in the researchers' engineered cells can sit in one of two positions, representing the 0s and 1s of digital data. "Essentially, if the DNA section points in one direction, it's a zero. If it points the other way, it's a one,"...

As Kent was riding home one night, he wondered why his bike's headlight, meant to illuminate the road ahead of him, was mounted on the handlebars. Why couldn't the light be closer to the ground? He put his engineering mind to work, and Revolights were born.
The Revolights bike lighting system consists of two narrow rings of LEDs that mount directly to each wheel...
The TakTik LunaTik compression molded band is made by hand-placing the various camo colored silicone bits in the tool. Each band is its own unique pattern. The LunaTik case is forged and CNC'd from aircraft grade aluminum, the hardware is PVD plated and the straps are made from compression molded high-grade silicone rubber with an anti-dust coating. All hardware is stainless steel.
