Silicon wafer imaging technology has been modified to scan the human body down at the level of a single cell  - zooming in and out of a joint in the body like Google Maps does from the sky.

Coupled with Google algorithms, the imaging system developed by German optical and industrial measurement manufacturer Zeiss is able to zoom in and out from the scale of the whole joint down to the cellular level, reducing to "a matter of weeks analyses that once took 25 years to complete," said Professor Knothe Tate of UNSW Australia.



Have you ever texted somebody saying how “ducking annoyed” you are at something? Or asked Siri on your iPhone to call your wife, but somehow managed to be connected to your mother-in-law?

If you have, you may have been a victim of a new challenge in computing: that fine line where we trust a computer to make predictions for us despite the fact that it sometimes gets them wrong.

In a recent survey 76% of young respondents listened to music from YouTube every day with Spotify coming in second. But YouTube is so popular for music listening and new music discovery that even active Spotify users still visited YouTube often to complement Spotify’s incomplete music selection. 

YouTube was also perceived as the most shareable music source by the students in their early 20s who participated in a recent Internet-based study.


Researchers have tested a range of neuroprosthetic devices, from wheelchairs to robots to advanced limbs, that work with their users to intelligently perform tasks.

They work by decoding brain signals to determine the actions their users want to take, and then use advanced robotics to do the work of the spinal cord in orchestrating the movements. The use of shared control - new to neuroprostheses - "empowers users to perform complex tasks," says José del R. Millán, who presented the new work at the Cognitive Neuroscience Society (CNS) conference in San Francisco today.
During the launch of the latest Soyuz to the space station Scott Kelly and Mikhail Kornienko calmly looked at an iPad.  Other than the cramped confines of the Soyuz capsule, and their space suits, they looked like business men discussing their presentation while flying economy class.  



With each beat of a healthy heart, an electrical signal moves from the upper to the lower chambers of the heart. As this signal moves, it results in the heart contracting and pumping blood. Congenital heart block is a defect of the heart's electrical system that originates in the developing fetus, greatly slowing the rate of the heart and impacting its ability to pump blood.

Although the condition can be diagnosed in utero, all attempts to treat the condition with a standard pacemaker have failed.  Each year, approximately 500 pregnancies in the U. S. are affected by such fetal heart block - those babies may soon have the perfect solution. 

In light of the news of another tragic airline crash, and following in the wake of several other high profile air disasters, it might be natural to ask whether air travel is becoming less safe.

In fact, according to the numbers, air travel is safer than at almost any point in the history of commercial flight.

While the number of fatalities in some recent crashes has been high, the number of overall fatal accidents in recent years has dropped to its lowest point since the dawn of the jet age. Also, as more and more people take to the skies each year, the numbers of fatalities per liftoff or per flight hour have also dropped dramatically.

Millions of people injure themselves each year lifting physically demanding things, with (insert absurd number here) of dollars in lost productivity, etc., etc.

Okay, enough of that, here is the fun part: Some day a cute 105 pound nurse may be able to lift your fat keester into a hospital bed after you injure yourself lifting heavy things incorrectly, and you will be able to thank 'soft' robotics.(1) Which is another way of saying that she might be wearing a power vest that gives her super strength.
Cyber warfare, killer robots, biological pandemics due to mad scientists, the Bulletin of the Atomic Scientists has grown since the old days of just figuring out how to kill nuclear power.
In cultural perception, an artificial hand looks something like a Steampunk reworking of a hand, with gears and pistons and rods. In the future, an artificial hand would look just like a hand, except with muscles made from smart metal wires.

Engineers at Saarland University have equipped an artificial hand with muscles made from  nickel-titanium shape-memory wire, enabling the fabrication of flexible and lightweight robot hands for industrial applications and novel prosthetic devices. The muscle fibers are composed of bundles of the ultra-fine nickel-titanium alloy wires, each about the width of a human hair, and they are able to tense and flex and the material has sensory properties allowing the artificial hand to perform extremely precise movements.
