Computers will be able to assess humans’ state of mind

Posted by in categories: biotech/medical, computing, robotics/AI, security

I see many uses for this such as provider services including front office & hospital admissions, security in assessing people in line or trying to gain entry, etc.


Machines are taking over more and more tasks. Ideally, they should also be capable to support the human in case of poor performance. To intervene appropriately, the machine should understand what is going on with the human. Fraunhofer scientists have developed a diagnostic tool that recognizes user states in real time and communicates them to the machine.

The camera firmly focuses on the driver’s eyes. If they are closed for more than one second, an alarm is triggered. This technique prevents the dangerous micro-sleep at the wheel. “It is not always as easy for a machine to detect what state the human is in, as it is in this case,” says Jessica Schwarz from the Fraunhofer Institute for Communication, Information Processing and Ergonomics FKIE in Wachtberg, just south of Bonn.

Virtual Light Particles May Boost Quantum Computing

Posted by in categories: computing, particle physics, quantum physics

A single photon can excite two or more atoms at the same time, scientists found. And the light particle would do so in a very counterintuitive way, by summoning one or more companion photons out of nothingness.

If you think of particles of light, or photons, as billiard balls, it makes intuitive sense that a single photon can excite a single atom.

The new, less intuitive finding depends on the strange nature of quantum mechanics, and might help improve advanced machines known as quantum computers, researchers said. Prior work suggested that such machines could simultaneously perform more calculations in one instant than there are atoms in the universe. [Warped Physics: 10 Effects of Faster-than-Light Travel].

Excellent write up on a paper submitted to the International Association for Cryptologic Research, by a group of UK and Belgian researchers are offering up a dig-sig scheme to assist in the addressing of Digital signatures (one of the fundamental parts of cryptography) in a post-quantum world. Expect the heat to rise on QC security as China’s launch date nears for the new Quantum Satellite.

SEED 2016: What can we do outside of a cell?

Posted by in categories: bioengineering, biotech/medical, computing

Nice.


When we think of synthetic biology, we often think of engineering a cell to give it some useful function. But SEED 2016 had quite a few speakers working outside of a biological cell. Some broke open cells to utilize just the cellular machinery to create “cell-free” systems. Others showed what could be done inside of the computer (in silico) to improve our understanding and prediction of synthetic gene networks. Here, we’re highlighting SEED speakers who showed how both of these approaches can advance synthetic biology.

Lab-on-a-Chip breakthrough aims to help physicians detect cancer and diseases at the nanoscale

Posted by in categories: biotech/medical, computing, nanotechnology, particle physics

Nice!


IBM scientists have developed a new lab-on-a-chip technology that can, for the first time, separate biological particles at the nanoscale and could help enable physicians to detect diseases such as cancer before symptoms appear.

As reported today in the journal Nature Nanotechnology (“Nanoscale Lateral Displacement Arrays for Separation of Exosomes and Colloids Down to 20nm”), the IBM team’s results show size-based separation of bioparticles down to 20 nanometers (nm) in diameter, a scale that gives access to important particles such as DNA, viruses and exosomes. Once separated, these particles can be analyzed by physicians to potentially reveal signs of disease even before patients experience any physical symptoms and when the outcome from treatment is most positive. Until now, the smallest bioparticle that could be separated by size with on-chip technologies was about 50 times or larger, for example, separation of circulating tumor cells from other biological components.

A Freaky Anti-Rubber Is Still Weirding Scientists Out

Posted by in categories: biotech/medical, computing, transportation

Imagine you wake up one morning burning to make the great physicist Max Planck’s face out of copper. (Just go with it.) Sure, you could sculpt it, but there’s a better way. Cut a flat copper sheet into a half-oval, and take a triangle out of the center of its straight edge. Divide it into smaller triangles, bend the sheet so that the two sides of the big triangle touch—and violà! A sheet of flat copper triangles has morphed to match every nook and cranny of Planck’s face. No sculpting required.

If that sounds like magic … well, that’s understandable, because we left a few steps out. Computer scientist Keenan Crane from Carnegie Mellon University actually did this with real copper, and you can see a computer model of the final product at the top of this article. Making Planck’s face wasn’t the point, of course: When Crane cut the sheet into carefully-designed triangles, he brought it into a class of materials known as auxetics, whose curious and complex properties have excited researchers for decades. Someday, auxetics could improve highway shock absorbers, form more comfortable and versatile shoes, and line veins that thicken when expanding.

At least, that’s what the grant applications say. “People give a lot of lip service to how it’s gonna change the world, in terms of curing cancer,” says Crane. “But at this stage people are still trying to figure out just basic questions.” Auxetics all started with a 1987 Science paper by engineer and professor Roderic Lakes. He reported a new kind of polymer foam that contradicted common sense. It expanded in one direction when stretched in another, and contracted in one direction when squeezed in another.
