Targets in the search for alien life

May 23, 2022 (Nanowerk News) Nearly half of Sun-size stars are binary. According to University of Copenhagen research, planetary systems around binary stars may be very different from those around single stars. This points to new targets in the search for extraterrestrial life forms. Since the only known planet with...

Microparticles with feeling

May 23, 2022 (Nanowerk News) The surface of a coral is rugged. Its hard skeleton is populated by polyps that stretch their tentacles into the surrounding water to filter out food. But how exactly does the water flow over the coral surface, what eddies and flows develop, and what does...

Researchers unveil a secret of stronger metals

May 21, 2022 (Nanowerk News) Forming metal into the shapes needed for various purposes can be done in many ways, including casting, machining, rolling, and forging. These processes affect the sizes and shapes of the tiny crystalline grains that make up the bulk metal, whether it be steel, aluminum or...

Mixing laser- and x-ray-beams

May 21, 2022 (Nanowerk News) Unlike fictional laser swords, real laser beams do not interact with each other when they cross – unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing can give rise to beams with changed colors and...

Bacterial enzyme produces biodegradable polymer

May 21, 2022 (Nanowerk News) Researchers discovered a bacterial enzyme, structurally characterized at the Advanced Light Source (ALS), that synthesizes a biopolymer whose repeating units are linked together in a way that had not been previously observed (ACS Central Science, "A Synthetic Gene Library Yields a Previously Unknown Glycoside Phosphorylase...
