Once operational, the SKA is expected to generate around an exabyte – a million terabytes - of data each day. Even sorting the junk is going to need plenty of computing power, but operations at that scale need to be frugal lest electricity costs alone make the SKA horribly expensive to operate.'

Similar to existing Kinect technology on the Xbox, HoloLens allows wearers to interact with computer programs and games in three dimensions, using their hands and speaking commands.
During the presentation, a developer walked onstage wearing HoloLens, and used her finger and a 3D-modeling program called Holo Studio to build a quadcopter drone before the audience, which could then be sent to a 3D printer.
Microsoft also showed a video of a NASA scientist sitting at a computer wearing HoloLens glasses, then stepping away from the desk into an immersive hologram of the surface of Mars. It's not yet Star Trek's Holodeck (video), but it's not so far off.'

Now researchers at UCLA have treated ASD mice with a neuropeptide--molecules used by neurons to communicate with each other--called oxytocin, and have found that it restores normal social behavior. In addition, the findings suggest that giving oxytocin as early as possible in the animal's life leads to more lasting effects in adults and adolescents. This suggests there may be critical times for treatment that are better than others.
The study appears in the January 21 online edition of the journal Science Translational Medicine.'

Radio-, X-ray- and visible light
A team of astronomers in Australia developed a technique to search for these 'Fast Radio Bursts', so they could look for the bursts in real time. The technique worked and now a group of astronomers, led by Emily Petroff (Swinburne University of Technology), have succeeded in observing the first 'live' burst with the Parkes telescope. The characteristics of the event indicated that the source of the burst was up to 5.5 billion light years from Earth.'

The team's record storage time of six hours is a major step towards a secure worldwide data encryption network based on quantum information, which could be used for banking transactions and personal emails.
"We believe it will soon be possible to distribute quantum information between any two points on the globe," said lead author Manjin Zhong, from the Research School of Physics and Engineering (RSPE) at The Australian National University (ANU).
"Quantum states are very fragile and normally collapse in milliseconds. Our long storage times have the potential to revolutionise the transmission of quantum information."
Quantum information promises unbreakable encryption because quantum particles such as photons of light can be created in a way that intrinsically links them. Interactions with either of these entangled particles affect the other, no matter how far they are separated.
The team of physicists at ANU and the University of Otago stored quantum information in atoms of the rare earth element europium embedded in a crystal.
Their solid-state technique is a promising alternative to using laser beams in optical fibres, an approach which is currently used to create quantum networks around 100 kilometres long.
"Our storage times are now so long that it means people need to rethink what is the best way to distribute quantum data," Ms Zhong said.
"Even transporting our crystals at pedestrian speeds we have less loss than laser systems for a given distance."
"We can now imagine storing entangled light in separate crystals and then transporting them to different parts of the network thousands of kilometres apart. So, we are thinking of our crystals as portable optical hard drives for quantum entanglement."
After writing a quantum state onto the nuclear spin of the europium using laser light, the team subjected the crystal to a combination of a fixed and oscillating magnetic fields to preserve the fragile quantum information.
"The two fields isolate the europium spins and prevent the quantum information leaking away," said Dr Jevon Longdell of the University of Otago.'
