Simple rod-shaped molecules with a single center of chirality self-assemble into helical structures at room temperature. Using soft X-ray resonant scattering at BESSY II, the scientists have now been able to determine the pitch of the helical structure with high precision. Their results indicate an extremely short pitch at only about 100 nanometres which would enable applications with particularly fast switching processes. https://www.sciencedaily.com/releases/2021/12/211206113047.htm ScienceDaily: Latest Science News urn:uuid:a73a4bd9-366e-91f3-16a9-e62bae129b71 Mon, 06 Dec 2021 10:30:47 -0600 The tiny male golden orb-weaving spider faces a considerable challenge when searching for a mate. He is a fraction of the size of the massive female, but must carefully enter her web and approach her without being noticed, because the cannibalistic female will kill and eat him if he makes one wrong move on her web. Add to this gamble the competition he faces from other males also on the delicate arena of the web, and you have a complex optimization problem that even human analysts would find daunting.

Researchers warn current efforts are overlooking huge swathes of diversity and opportunity. Their analysis found that nearly 3,300 animal species have had their genomes sequenced and assembled, a process that gives organizational context to an organism's DNA. While the rate is picking up, the number is small in comparison to the world's 1.66 million animal species, and vertebrates make up the lion's share of current sequences. They account for 54% of all the assemblies, despite representing only 3.9% of animal species. In contrast, the invertebrates of the Arthropoda phylum, which includes insects and spiders, comprise only 34% of current datasets while representing 78.5% of all species. https://www.sciencedaily.com/releases/2021/12/211206090617.htm ScienceDaily: Latest Science News urn:uuid:3a302787-cc0d-01a3-dbf6-b907992723fd Mon, 06 Dec 2021 08:06:17 -0600 An international research team has used the X-ray laser European XFEL to gain new insights into how radiation damage occurs in biological tissue.
