A team of scientists from Oxford University has shown how the natural movement of bacteria could be harnessed to assemble and power microscopic ‘windfarms’ — or other man-made micromachines such as smartphone components.

The study, published in the journal Science Advances (“Active micromachines: Microfluidics powered by mesoscale turbulenceence”), uses computer simulations to demonstrate that the chaotic swarming effect of dense active matter such as bacteria can be organised to turn cylindrical rotors and provide a steady power source.

Satya Nadella bounded into the conference room, eager to talk about intelligence. I was at Microsoft’s headquarters in Redmond, WA, and the company’s CEO was touting the company’s progress in building more intelligent apps and services. Each morning, he told me, he puts on a HoloLens, which enables him to look at a virtual, interactive calendar projected on a wall of his house. Nadella appeared giddy as he described it. The system was intelligent, productive, and futuristic: everything he hopes Microsoft will be under his leadership.

No matter where we work in the future, Nadella says, Microsoft will have a place in it. The company’s “conversation as a platform” offering, which it unveiled in March, represents a bet that chat-based interfaces will overtake apps as our primary way of using the internet: for finding information, for shopping, and for accessing a range of services. And apps will become smarter thanks to “cognitive APIs,” made available by Microsoft, that let them understand faces, emotions, and other information contained in photos and videos.

Microsoft argues that it has the best “brain,” built on nearly two decades of advancements in machine learning and natural language processing, for delivering a future powered by artificial intelligence. It has a head start in building bots that resonate with users emotionally, thanks to an early experiment in China. And among the giants, Microsoft was first to release a true platform for text-based chat interfaces — a point of pride at a company that was mostly sidelined during the rise of smartphones.

You got to luv this one.


The security agency must defend itself in a US appeals court for violating the rights of a convicted bomber by supposedly illegally spying on him.

A US appeals court will weigh a constitutional challenge on Wednesday to a warrantless government surveillance program, brought by an Oregon man found guilty of attempting to detonate a bomb in 2010 during a Christmas tree-lighting ceremony.

The case before a three-judge panel of the 9th US Circuit Court of Appeals is the first of its kind to consider whether a criminal defendant’s constitutional privacy rights are violated under a National Security Agency (NSA) program that allows spying on Americans’ international phone calls and internet communications.

Researcher Tim Burgess added atoms of zinc to lasers one hundredth the diameter of a human hair and made of gallium arsenide — a material used extensively in smartphones and other electronic devices.

The impurities led to a 100 times improvement in the amount of light from the lasers.

“Normally you wouldn’t even bother looking for light from nanocrystals of gallium arsenide — we were initially adding zinc simply to improve the electrical conductivity,” said Mr Burgess, a PhD student in the ANU Research School of Physics and Engineering.

One day in the future, we’ll look back in wonder at how our physical objects used to be singular, disconnected pieces of matter.

We’ll be in awe of the fact that a car used to be just a piece of metal full of gears and belts that we would drive from one place to another, that a refrigerator was a box that kept our food cold — and a phone was a piece of plastic we used to communicate to one other person at a time.

Although we love them to pieces, eventually smart phones won’t be the only way we communicate and spend our time. Scientists predict we might end up using neural networks to play candy crush, or we could spend all our time using smart eyewear.

They still have a few issues to iron out, but there’s a new reason that smart eyewear might be a good option — night vision! Google’s just submitted a patent that suggests it’s planning on adding the future at some point.

Seriously though, we’re keen for anything to stop us tripping over stuff in the middle of the night.

3D printing has has a presence in the medical industry since the 1980s for modelling body parts that are otherwise untouchable without invasive surgery, but research into the potential of this technology is bringing clinicians closer to getting a good look up close at the real thing. Instead of scans, what about injecting a camera no bigger than a grain of salt into your patient?

A group of German researchers have been working on a complex lens system that is small enough to fit inside a syringe, and applications aren’t just limited to the medical industry. They have the potential to also be used in many products which need parts to be as small and light as possible, such as drones and smart phones.

Technology can be awkward. Our pockets are weighed down with ever-larger smartphones that are a pain to pull out when we’re in a rush. And attempts to make our devices more easily accessible with smartwatches have so far fallen flat. But what if a part of your body could become your computer, with a screen on your arm and maybe even a direct link to your brain?

Artificial electronic skin (e-skin) could one day make this a possibility. Researchers are developing flexible, bendable and even stretchable electronic circuits that can be applied directly to the skin. As well as turning your skin into a touchscreen, this could also help replace feeling if you’ve suffered burns or problems with your nervous system.

The simplest version of this technology is essentially an electronic tattoo. In 2004, researchers in the US and Japan unveiled a pressure sensor circuit made from pre-stretched thinned silicon strips that could be applied to the forearm. But inorganic materials such as silicon are rigid and the skin is flexible and stretchy. So researchers are now looking to electronic circuits made from organic materials (usually special plastics or forms of carbon such as graphene that conduct electricity) as the basis of e-skin.
