That’s the future that designers of E-textiles, or smart textiles, want to build.
Fashion trial and error: Smart textiles embed flexible electronics into clothing to give them similar tracking and monitoring capabilities as smartwatches. Today’s market, however, doesn’t have the same kind of demand as it has for the devices we wear on our wrists.
Many of these systems are kept out of equilibrium because individual constituents have their own power source — ATP for cells, gas for cars. But all these extra energy sources and mismatched reactions make for a complex dynamical system beyond the reach of statistical mechanics. How can we analyze phases in such ever-changing systems?
Vitelli and his colleagues see an answer in mathematical objects called exceptional points. Generally, an exceptional point in a system is a singularity, a spot where two or more characteristic properties become indistinguishable and mathematically collapse into one. At an exceptional point, the mathematical behavior of a system differs dramatically from its behavior at nearby points, and exceptional points often describe curious phenomena in systems — like lasers — in which energy is gained and lost continuously.
Now the team has found that these exceptional points also control phase transitions in nonreciprocal systems. Exceptional points aren’t new; physicists and mathematicians have studied them for decades in a variety of settings. But they’ve never been associated so generally with this type of phase transition. “That’s what no one has thought about before, using these in the context of nonequilibrium systems,” said the physicist Cynthia Reichhardt of Los Alamos National Laboratory in New Mexico. “So you can bring all the machinery that we already have about exceptional points to study these systems.”
The uncertainty principle, first introduced by Werner Heisenberg in the late 1920’s, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can also behave like waves. As a result, particles cannot have a well-defined position and momentum simultaneously. For instance, measuring the momentum of a particle leads to a disturbance of position, and therefore the position cannot be precisely defined.

Defense Ministry expects to have a bolstered intercept system by late 2020s.
TOKYO — The Japanese Defense Ministry will develop a means to intercept hostile missiles using magnetically powered projectiles, sources told Nikkei Asia, as the nation scurries to respond to the hypersonic weapons being developed by China, North Korea and Russia.
Just seven months after it announced a milestone record for plasma fusion, the Chinese Academy of Sciences has absolutely smashed it.
Their ‘artificial Sun’ tokomak reactor is has maintained a roiling loop of plasma superheated to 120 million degrees Celsius (216 million degrees Fahrenheit) for a gobsmacking 1,056 seconds, the Institute of Plasma Physics reports.
This also beats the previous record for plasma confinement of 390 seconds, set by the Tore Supra tokamak in France in 2003.

Robots patrolling around shopping malls, casinos and places of work actively looking for criminal activity might no longer be something straight out of a science fiction novel or movie. Knightscope, Inc., a Silicon Valley Based startup, is building and deploying fully autonomous security robots that deter, detect and report crime.
