Supercomputer simulations show that at the atomic level, material stress doesn't behave symmetrically.  Extracting gas from new sources is vital in order to supplement dwindling conventional supplies.  The findings revealed that the primary driver of this type of fluid flow—called solutal convection — had been overlooked. What's more, once this driver is accounted for, it completely flips the expected flow outcomes.  By using this method for microscopic failure analysis, researchers and manufacturers could improve the reliability of the MEMS components that they are developing, ranging from miniature robots and drones to tiny forceps for eye surgery and sensors to detect trace amounts of toxic chemicals.  A KAIST team developed an optical technique to change the color (frequency) of light using a spatiotemporal boundary.  Researchers from the Structured Light group from the School of Physics at the University of the Witwatersrand in Johannesburg, South Africa, have found a way to use the full beam of a laser single cells in a human body, tiny particles in small volume chemistry, or working on future on-chip devices.
