Noninvasive Brain Imaging Shows Readiness of Trainees To Perform Operations

Study led by Rensselaer Polytechnic Institute faculty and graduate student shows that surgeons who trained on simulator had higher level of cortical activation and faster times for cutting tasks. While simulation platforms have been used to train surgeons before they enter an actual operating room (OR), few studies have evaluated how well trainees transfer those skills from the simulator to the OR.

First-Of-Its-Kind Bioengineered Robotic Hand To Sense Touch

The sense of touch is often taken for granted. For someone without a limb or hand, losing that sense of touch can be devastating. While highly sophisticated prostheses with complex moving fingers and joints are available to mimic almost every hand motion, they remain frustratingly difficult and unnatural for the user. This is largely because they lack the tactile experience that guides every movement.

Norwegian ultrasound researchers among the very best

This is confirmed by the international journal Ultrasound in Medicine and Biology. Researchers at SINTEF, NTNU and St. Olavs Hospital at the National Competence Service for ultrasound and image processing have long been working on the use of 3D ultrasound in various clinical procedures.

Essential quantum computer component downsized by two orders of magnitude

Researchers at IST Austria have built compact photon directional devices. Their micrometer-scale, nonmagnetic devices route microwave photons and can shield qubits from harmful noise. Qubits, or quantum bits, are the key building blocks that lie at the heart of every quantum computer. In order to perform a computation, signals need to be directed to and from qubits.

New way to write magnetic info could pave the way for hardware neural networks

Researchers have shown how to write any magnetic pattern desired onto nanowires, which could help computers mimic how the brain processes information. Much current computer hardware, such as hard drives, use magnetic memory devices. These rely on magnetic states – the direction microscopic magnets are pointing – to encode and read information.

Three-Dimensional Nanomagnets for the computer of tomorrow

Since the late 60´s electronic devices have stored and transmitted information (bits) in two-dimensional circuits. Now, researchers at the University of Cambridge have been able to break this barrier by creating a nanoscale magnetic circuit capable of moving information along the three dimensions of space. This breakthrough could lead to an important increase in storage and processing capacities of electronic devices over those used today.

This is the world’s first autonomus battery-powered containtership

Each year, 40,000 diesel-fuelled lorries pass through the gates of Yara’s fertiliser manufacturing plant in Porsgrunn, Norway. But not for long. In a few years time, all these loads will be transferred to an autonomous ship: A battery driven container vessel, the Yara Birkeland. This is good news for all those concerned about local noise and air pollution, but the real benefit will be seen when such vessels are being mass-produced and making a global contribution to reducing the effects of climate change.

What Is the Computational Power of the Universe?

Can a close look at the universe give us solutions to problems too difficult even for a planet-sized computer to solve? National Institute of Standards and Technology physicist Stephen Jordan asks, “What if we consider the cosmos to be the output of a 13.7-billion-year computation?” After all, computers crunch numbers to simulate complex change and the universe has undergone billions of years of change in accordance with the laws of nature.

Streaming On A Wireless Power Connection

Researchers from North Carolina State University have developed a system that can simultaneously deliver watts of power and transmit data at rates high enough to stream video over the same wireless connection. By integrating power and high-speed data, a true single “wireless” connection can be achieved.

Lighting the way to switch chemical reaction pathways 0

Could the manufacture of the integrated circuits and chips for our everyday electronic devices be made simpler, safer and cheaper simply by being able to switch coloured light on and off? Researchers from QUT, Germany’s Karlsruhe Institute of Technology (KIT) and Belgium’s Ghent University have stepped towards this by pioneering a system that modulates visible, coloured light to change the reactions of a powerful chemical coupling agent.

An eye for high explosives

Fluorescent polymer points the finger at traces of explosive devices. Bomb plots could be thwarted with the help of a portable system for detecting traces of high explosives using fluorescent polymer nanoparticles1, developed by A*STAR. Coated on to paper, these polymers display an explosive-detection performance far more robust than previous materials with similar properties.

Understanding how electrons turn to glass

New insights into the behaviour of electrons as liquids transform to glass are deepening our understanding of this transition phase. Researchers at Tohoku University have gained new insight into the electronic processes that guide the transformation of liquids into a solid crystalline or glassy state. The ability of some liquids to transition into glass has been exploited since ancient times. But many fundamental aspects of this transition phase are far from understood.

Inaugural Data Science Workshop highlights social sciences

From quantifying the wisdom of crowds to measuring polarization in political speech, data science is enhancing a wide range of social science research. On Oct. 20, Yale held its first Data Science Workshop, a daylong event focused on computational social science. Computer science professor Dragomir Radev and other organizers said the workshop reflected Yale’s increased commitment to data science, and may become part of an ongoing series of workshops.
