A new experimental method permits the X-ray analysis of amyloids, a class of large, filamentous biomolecules which are an important hallmark of diseases such as Alzheimer’s and Parkinson’s. An international team of researchers headed by DESY scientists has used a powerful X-ray laser to gain insights into the structure of different amyloid samples.
Scientists have unlocked the secrets of how some predatory spiders catch their prey whilst hunting by successfully training one to jump different distances and heights for the first time.
For decades, scientists have tried to prove that one of the most peculiar properties of quantum mechanics isn’t just a mathematical quirk, but a real feature of the physical world.
An international team of physicists found a new way to improve images obtained by fluorescence microscopy. The method is based on adaptive optics and implies an automatic correction of aberrations. Moreover, this correction is based on the quality of individual pixels, rather than the image as a whole.
Prof. Chuan-Feng Li’s Group of CAS Key Laboratory of Quantum Information has made new progress in the study of fundamental problems in quantum mechanics. Chuan-Feng Li, Bi-Heng Liu, and others collaborated with theoretical physicists from Spain, Hungary, and Germany to demonstrate for the first time the existence of stronger-than-binary correlations in quantum mechanics.
In the wake of its recent discovery of a flat form of gallium, an international team led by scientists from Rice University has created another two-dimensional material that the researchers said could be a game changer for solar fuel generation.
Transitions between different phases of matter are part of our day-to-day lives: when water freezes, for example, it passes from liquid to solid state. Some of these transitions may be of a different kind, resulting from so-called topological excitations that force all the particles to act in unison.
Circulators are important components in communication technology. Their unique way of routing light usually requires centimeter-sized magnets, which are difficult to miniaturize for use on optical chips. Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light.
To get the extremely high-resolution images vital to study new materials, microbes, and more, scientists often build microscopes based on optical vortices. Forming these tiny tornadoes of light is done using quartz or liquid crystals.
The precision of measuring nanoscopic structures could be substantially improved, thanks to research involving the University of Warwick and QuantIC researchers at the University of Glasgow and Heriot Watt University into optical sensing.
