How chaos could improve speech recognition
If you’ve ever used speech recognition software, you’ll know how often it fails to work well. Recognition rates are nowhere near what is needed for anything but the simplest applications. So a new approach for analysing speech by Yuri Andreyev and Maxim Koroteev at the Institute of Radioengineering and Electronics of the Russian Academy of…

A clue in the puzzle of perfect synchronization in the brain
“Two identical chaotic systems starting from almost identical initial states, end in completely uncorrelated trajectories. On the other hand, chaotic systems which are mutually coupled by some of their internal variables often synchronize to a collective dynamical behavior,” write Meital Zigzag at Bar-Ilan University in Israel and colleagues o the arXiv today. And perhaps the…

How to build a quantum internet
You could be forgiven for thinking that a quantum version of the internet is a couple of-afternoons-in-the-lab away from being plumbed into your living room. In reality, there are significant engineering challenges to overcome, says Jeff Kimble from the California Institute of Technology in Pasadena and one of the leading thinkers on the links between…

Solar system filled with dark matter, say astronomers
As the evidence for dark matter builds, astronomers have begun modelling how it ought to be distributed around the cosmos. They’ve shown how it must be distributed on the largest scale to make clusters of galaxies form in the way we see, various other simulations show that it forms a kind of halo around galaxies…

The birth of piezo-spintronics
Everything we do with electrons depends on their charge, for example the whole of electronics is based around an electron’s negative charge. But electrons have another property, their spin, that could also be used to manipulate them. So a lot of engineers are trying to think up ways we can fiddle with an electron’s spin…

The birth and death of spookytechnology
Quantum mechanics is seriously sexy . That’s what keeps the public coming back for more with the drool hangin from their spittle-flecked lips (repeat this often enough and it might actually come true). Without a sexy lingo to bamboozle and baffle, physics eggs ain’t got nothing to keep people’s attention ‘cept their rugged good looks…

Magnetic cloaking
The world has gone crazy over metamaterials cos they can be used to build invisibility cloaks, as ya’ll saw just the other week. There’s usually some drawback the media coverage never tells ya which means that we ain’t gonna see no Harry Potter-type invisibility cloaks any time soon. But that hasn’t stopped the living God…

Crowdquakes–the killers that cause stampedes
The squeeze ‘n’ shove of Mecca pilgrimages are a-mighty frightenin. Thousands of people have been died in em. Now video analysis shows that a remarkable new phenomenon called crowdquakes are behind these stampedes. The analysis also suggests how stampedes might be prevented. Dizzy Dirk Helbing and his mates at the Swiss Federal Institute of Technology…
