A robotic police officer is making its debut on the streets of Dubai tomorrow night — and I hope everyone there has watched Robocop.

The uniformed bot greeted visitors to the Gulf Information Security and Expo Conference. After the conference wraps on Tuesday, it will be deployed to the streets of Dubai.

The robot rolls around on wheels. It can salute, bow, speak in multiple languages, and recognize hand gestures from up to 1.5 meters away, according to the Khaleej Times. It also has a tablet lodged in its chest which civilians can use to report crimes, according to The Daily Mail. It was designed by the Dubai police, with assistance from IBM’s Watson and Google.

Despite the NSA confirming the existence of Skynet, we all should be grateful that technology has not yet advanced to the stage where a liquid metal T-1000 terminator can shape-shift its way into your home and demand to see John Connor.

But scientists in China are making a solid effort make a less sinister version of this scenario at reality, by creating liquid metal droplets that could one day make “self-powered liquid metal machines” a real possibility.

Because of their excellent conductivity, low toxicity, and shape-shifting abilities, liquid metal alloys have been put to good use in targeting cancer cells, creating nature-inspired self-fuelled motors for robots, and many other liquid metal biomaterials.

Many rain jackets have zippers at the armpits that, when opened, let out perspiration and funk that would otherwise stay trapped inside. But researchers from the Massachusetts Institute of Technology have created a prototype of a wearable that vents itself automatically in response to sweat—and it does so using bacteria.

Wen Wang, the lead author of a new study about biohybrid wearables in the journal Science Advances, says that the garment with bacteria-triggered vents represents just a stepping stone on their way to creating shirts that do something even better: produce a pleasant smell when you sweat.

To make the prototype garment, the researchers experimented with different structures of latex and bacteria, says Wang, a bioengineer and former research scientist at MIT’s Media Lab and the university’s department of chemical engineering. One such configuration involved just two layers: bacteria on one side, and latex on the other. But what worked best for creating the vented wearable was coating latex on both sides with a type of bacteria called B. subtilis.

Lowe’s is making it easier for employees to stock shelves.

For the first time a major physics problem has been proved unsolvable, meaning that no matter how accurately a material is mathematically described on a microscopic level, there will not be enough information to predict its macroscopic behaviour.

The research, by an international team of scientists from UCL, the Technical University of Music and the Universidad Complutense de Madrid – ICMAT, concerns the spectral gap, a term for the energy required for an electron to transition from a low-energy state to an excited state.

Spectral gaps are a key property in semiconductors, among a multitude of other materials, in particular those with superconducting properties. It was thought that it was possible to determine if a material is superconductive by extrapolating from a complete enough microscopic description of it, however this study has shown that determining whether a material has a spectral gap is what is known as “an undecidable question”.

But there’s another significant finding: that human split occurred in the eastern Mediterranean and not Africa, as it is believed.

A jawbone discovered by German troops in Athens during the Second World War could be evidence that apes and humans diverged 200,000 years earlier than the current theory says.

Chimpanzees and bonobos are the nearest known relatives to humans, sharing 99 per cent of our DNA. It’s believed that we split between five and seven million years ago.

The galaxy M87 emits a jet of plasma that looks like it’s breaking the cosmic speed limit – here’s how it manages the trick.

I wonder if this will allow the body’s current healing abilities to remain robust or will the body’s healing abilities fall off as it will not have to work as hard.

In the near future, tiny microscopic robots will fix our cells so that they never get old or fall apart.
