In Brief:
The laws of thermodynamics are some of the most important principles in modern physics, because they define how three fundamental physical quantities — temperature, energy, and entropy — behave under various circumstances.
But now physicists say they’ve found a loophole in one of these laws, and it could create scenarios in which entropy — or disorder — actually decreases with time.
Thanks to modern physics, almost everything in the Universe can be explained according to two theories: general relativity for the big stuff like stars, galaxies, and the Universe itself; and quantum mechanics, for behaviours on the atomic scale.
“In his final months on the job, US Secretary of Transportation Anthony Foxx has been vocal about the pressing need to repair America’s broken infrastructure, and all the ways in which technology will fundamentally change the way we move.”

When it comes to the placement of interior lighting, much of the thought involved tends to relate to reaching nearby outlets. But the latest lights Toronto-based Nanoleaf may end up providing creative individuals one extra element to puzzle over. The Nanoleaf Aurora Smarter Kit is designed to be a modular lighting solution, featuring WiFi-controlled, color-adjustable, triangular panels that snap together like Lego.

Food is one of life’s absolute necessities and one that people take great pleasure from, so it’s no surprise that the future of food is one of those topics that always draws significant interest. So what will we be tucking into in the year 2036? A plate of bugs with a side order of seaweed? A glass of milky liquid? Cajun Swedish fusion cuisine? Or will it be a world of shortages where we munch on government issue Soylent Green and try not to think about where it came from? Take your places at table and join us as we take a look at what mealtimes in the future might look like.
The strength of spinach isn’t only in its nutrients, but also in its ability to be hacked to function as a sensor, according to researchers at the Massachusetts Institute of Technology. An MIT team used wonder-material carbon nanotubes to give the greens the ability to detect explosives and wirelessly transmit information to a mobile device.
MIT engineers applied a solution of nanoparticles to the underside of the leaves, allowing them to be taken up into the mesophyll layer where photosynthesis takes place. The embedded nanotubes then acted as sensors able to detect nitroaromatic compounds – which are often used in explosives like land mines – in the groundwater taken up by the plants’ roots.
If the chemicals are present in the water the plant is feeding from, the carbon nanotubes in the leaves emit a fluorescent signal that can be picked up with an infrared camera when a laser is shined on the leaves. The researchers hooked up such a camera to an inexpensive Raspberry Pi system and set it to email the user when the compounds were detected.
