Scientists harness bacteria to create ’living’ liquid crystals
Liquid crystals are widely used in technologies such as displays, which manipulate their orientation to display colors across the spectrum. In traditional displays, liquid crystals are stationary and uniform, free of defects. But that stillness can be altered by adding bacteria to the crystals, creating what scientists and engineers call "living liquid crystals": materials that can act autonomously.

Visualising strong magnetic fields with neutrons
Visualising strong magnetic fields with neutrons
Researchers at the Paul Scherrer Institute PSI have developed a new method with which strong magnetic fields can be precisely measured. They use neutrons obtained from the SINQ spallation source. In the future, it will therefore be possible to measure the fields of magnets that are already installed in devices and thus are inaccessible by other probing techniques.

Quantum gravity's tangled time
Quantum gravity’s tangled time
The theories of quantum mechanics and gravity are notorious for being incompatible, despite the efforts of scores of physicists over the past fifty years. However, recently an international team of researchers led by physicists from the University of Vienna, the Austrian Academy of Sciences as well as the University of Queensland (AUS) and the Stevens Institute of Technology (USA) have combined the key elements of the two theories describing the flow of time and discovered that temporal order between events can exhibit genuine quantum features.

Making biominerals: nature’s recipe is old, evolved more than once
In recent years, scientists have teased out many of the secrets of biomineralization, the process by which sea urchins grow spines, mollusks build their shells and corals make their skeletons, not to mention how mammals and other animals make bones and teeth. The materials that animals make from scratch to build protective shells, razor sharp teeth, load-bearing bones and needlelike spines are some of the hardest and most durable substances known.

Atomically thin heat shield protects electronics
Atomically thin materials developed by Stanford researchers could create heat-shields for cell phones or laptops that would protect people and temperature-sensitive components and make future electronic gadgets even more compact. Excess heat given off by smartphones, laptops and other electronic devices can be annoying, but beyond that it contributes to malfunctions and, in extreme cases, can even cause lithium batteries to explode.

Physicists Develop "Time Machine" for Materials Science
Physics experiments are often time-consuming and expensive. Sometimes scientists do not realize until the very end that they have been using the wrong calibration for measurements the whole time. What if there were a way to go back in time to the start of the experiment and re-examine the data? Researchers at Martin Luther University Halle-Wittenberg (MLU), Freie Universität Berlin, and the Technical University of Munich (TUM) hope to create a machine that would make that possible.

Scientists can now control thermal profiles at the nanoscale
At human scale, controlling temperature is a straightforward concept. Turtles sun themselves to keep warm. To cool a pie fresh from the oven, place it on a room-temperature countertop. At the nanoscale - at distances less than 1/100th the width of the thinnest human hair - controlling temperature is much more difficult.
