COSMIC, a multipurpose X-ray instrument at Lawrence Berkeley National Laboratory s (Berkeley Lab s) Advanced Light Source (ALS), has made headway in the scientific community since its launch less than 2 years ago, with groundbreaking contributions in fields ranging from batteries to biominerals.
COSMIC is the brightest X-ray beamline at the ALS, a synchrotron that generates intense light - from infrared to X-rays - and delivers it to dozens of beamlines to carry out a range of simultaneous science experiments. COSMIC s name is derived from coherent scattering and microscopy, which are two overarching X-ray techniques it is designed to carry out.

Breakthrough greatly enhances the ultrafast resolution achievable with X-ray free-electron lasers.
A large international team of scientists from various research organizations, including the U.S. Department of Energy s (DOE) Argonne National Laboratory, has developed a method that dramatically improves the already ultrafast time resolution achievable with X-ray free-electron lasers (XFELs). It could lead to breakthroughs on how to design new materials and more efficient chemical processes.

It is millions of trillions of times brighter than the sunlight and a whopping 1,000 trillionth of a second, appropriately called the instantaneous light. It is the X-ray Free Electron Laser (XFEL) light that opens a new scientific paradigm. Combining it with AI, an international research team has succeeded in filming and restoring the 3D structure of nanoparticles that share structural similarities with viruses. With the fear of a new pandemic growing around the world due to COVID-19, this discovery is attracting the attention among academic circles for imaging the structure of the virus with both high accuracy and speed.

Researchers of the Center for Photonics and Two-Dimensional Materials at MIPT, together with their colleagues from Spain, Great Britain, Sweden, and Singapore, including co-creator of the world s first 2D material and Nobel laureate Konstantin Novoselov, have measured giant optical anisotropy in layered molybdenum disulfide crystals for the first time. The scientists suggest that such transition metal dichalcogenide crystals will replace silicon in photonics. Birefringence with a giant difference in refractive indices, characteristic of these substances, will make it possible to develop faster yet tiny optical devices. The work is published in the journal
Nature Communications.
Targeted, efficient and with few side effects: A new method for combating periodontitis could render the use of broad-spectrum antibiotics superfluous. It was developed and tested for the first time by a team from Martin Luther University Halle-Wittenberg (MLU), the Fraunhofer Institute for Cell Therapy and Immunology IZI and Periotrap Pharmaceuticals GmbH. The aim is to neutralise only bacteria that cause periodontitis while sparing harmless bacteria. The study appeared in the
