Topological insulators are quantum materials, which, due to their exotic electronic structure, on surfaces and edges conduct electric current like metal, while acting as an insulator in bulk. Scientists have now demonstrated how to tell apart topological materials from their regular — trivial — counterparts within a millionth of a billionth of a second by probing it with ultra-fast laser light.
Read moreThe largest experiment to date on mobile typing sheds new light on average performance of touchscreen typing and factors impacting the text input speed. Researchers analyzed the typing speed of tens of thousands of users on both phones and computers. Their main finding is that typing speeds on smartphones are now catching up with physical keyboards.
Read moreAccording to Einstein, light consists of particles (photons) that transfer only quantized energy to the electron of the atom. If the photon's energy is sufficient, it knocks the electrons out of the atom. But what happens to the photon's momentum in this process? Physicists are now able to answer this question. To do so, they developed and constructed and new spectrometer with previously unattainable resolution.
Read moreIn 2 breakthroughs in the realm of photonics, researchers are reporting the successful demonstration of an LED (light-emitting diode) based on half-light half-matter quasiparticles in atomically thin materials. This is also the first successful test of an electrically driven light emitter using atomically thin semiconductors embedded in a light trapping structure (optical cavity).

Read moreThe team behind the revolutionary 3D SCAPE microscope announces today a new version of this high-speed imaging technology. They used SCAPE 2.0 to reveal previously unseen details of living creatures — from neurons firing inside a wriggling worm to the 3D dynamics of the beating heart of a fish embryo, with far superior resolution and at speeds up to 30 times faster than their original demonstration.
Read moreResearchers have built a new tool to study molecules using a laser, a crystal and light detectors. This new technology will reveal nature's smallest sculptures — the structures of molecules — with increased detail and specificity.
Read moreResearchers have developed an optical system that accurately measures the flow of extraordinarily tiny amounts of liquids — as small as 10 billionths of a liter (nanoliters) per minute.
Read moreResearchers set out to untangle the mysterious interactions in mixtures of proteins and gold nanorods. Their experiments revealed multilevel chirality in the way proteins prompt nanoparticles to align and in how the particles' plasmons respond to light in the proteins' presence.
