Steerable soft robots could enhance medical applications

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

Borrowing from methods used to produce optical fibers, researchers from EPFL and Imperial College have created fiber-based soft robots with advanced motion control that integrate other functionalities, such as electric and optical sensing and targeted delivery of fluids.

In recent decades, catheter-based surgery has transformed medicine, giving doctors a minimally invasive way to do anything from placing stents and targeting tumors to extracting tissue samples and delivering contrast agents for medical imaging. While today’s catheters are highly engineered robotic devices, in most cases, the task of pushing them through the body to the site of intervention continues to be a manual and time-consuming procedure.

Combining advances in the development of functional fibers with developments in smart robotics, researchers from the Laboratory of Photonic Materials and Fiber Devices in EPFL’s School of Engineering have created multifunctional catheter-shaped soft robots that, when used as catheters, could be remotely guided to their destination or possibly even find their own way through semi-autonomous control. “This is the first time that we can generate soft catheter-like structures at such scalability that can integrate complex functionalities and be steered, potentially, inside the body,” says Fabien Sorin, the study’s principal investigator. Their work was published in the journal Advanced Science.

Scientists Invent ‘Quantum Watch’, a Mind-Bending New Way to Measure Time

Posted by in categories: innovation, quantum physics

“To our knowledge, the concept of obtaining time fingerprints, and therefore avoiding the need to measure time zero, is completely novel,” Berholts said in an email. She added that the new invention is a watch, not a clock, because “a clock requires keeping track of time” whereas “a watch simply provides the time.”

“The quantum watch provides a fingerprint representing a specific time, and hence only requires interaction when initiating and reading out the time,” she explained. “All other devices require keeping track of time. This differentiation comes from the fact that the quantum watch, unlike all the other clocks, measures times in a different way.”

Chiral orbit currents create new quantum state

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

Physicists have discovered a new quantum state in a material with the chemical formula Mn3SiTe6. The new state forms due to long-theorized but never previously observed internal currents that flow in loops around the material’s honeycomb-like structure. According to its discoverers, this new state could have applications for quantum sensors and memory storage devices for quantum computers.

Mn3SiTe6 is a ferrimagnet, meaning that its component atoms have opposing but unequal magnetic moments. It usually behaves like an insulator, but when physicists led by Gang Cao of the University of Colorado, Boulder, US, exposed it to a magnetic field applied along a certain direction, they found that it became dramatically more conducting – almost like it had morphed from being a rubber to a metal.

This effect, known as colossal magnetoresistance (CMR), is not itself new. Indeed, physicists have known about it since the 1950s, and it is now employed in computer disk drives and many other electronic devices, where it helps electric currents shuttle across along distinct trajectories in a controlled way.

Mars Once Had So Much Water, It Could Have Been An Ocean World, Scientists Say

Posted by in category: space

Today, Mars is colloquially known as the ‘Red Planet’ on account of how its dry, dusty landscape is rich in iron oxide (aka. ‘rust’). In addition, the atmosphere is extremely thin and cold, and no water can exist on the surface in any form other than ice.

But as the Martian landscape and other lines of evidence attest, Mars was once a very different place, with a warmer, denser atmosphere and flowing water on its surface.

For years, scientists have attempted to determine how long natural bodies existed on Mars and whether or not they were intermittent or persistent.

Completing Einstein’s Theories — A Particle Physics Breakthrough

Posted by in categories: information science, particle physics

Osaka University researchers show the relativistic contraction of an electric field produced by fast-moving charged particles, as predicted by Einstein’s theory, which can help improve radiation and particle physics research.

Over a century ago, one of the most renowned modern physicists, Albert Einstein, proposed the ground-breaking theory of special relativity. Most of everything we know about the universe is based on this theory, however, a portion of it has not been experimentally demonstrated until now. Scientists from Osaka University’s Institute of Laser Engineering utilized ultrafast electro-optic measurements for the first time to visualize the contraction of the electric field surrounding an electron beam traveling at near the speed of light and demonstrate the generation process.

According to Einstein’s theory of special relativity, one must use a “Lorentz transformation” that combines space and time coordinates in order to accurately describe the motion of objects passing an observer at speeds near the speed of light. He was able to explain how these transformations resulted in self-consistent equations for electric and magnetic fields.
