Too dry, too hot, or too wet: Increasing weather persistence in European summer ScienceDaily: Latest Science News urn:uuid:f1ae4cf5-daac-5406-0773-5e70d3865bcd Mon, 06 Dec 2021 10:30:59 -0600 Global warming makes long lasting weather situations in the Northern hemisphere's summer months more likely -- which in turn leads to more extreme weather events, a novel analysis of atmospheric images and data finds. These events include heatwaves, droughts, intense rainy periods. Especially in Europe, but also in Russia, persistent weather patterns have increased in number and intensity over the last decades with weather extremes occurring simultaneously at different locations.

Liquid crystals for fast switching devices ScienceDaily: Latest Science News urn:uuid:cd86c047-c9df-6115-fb72-fb4017e1b533 Mon, 06 Dec 2021 10:30:49 -0600 An international team has investigated a newly synthesized liquid-crystalline material that promises applications in optoelectronics. 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. Male spiders are attracted by a female like planets orbiting a star 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. Yet these little spiders barely have what we would recognize as a brain. How then do they manage?

This lowered risk persisted for at least a decade after surgery. Cataract surgery was also associated with lower risk of Alzheimer disease dementia specifically. Discovering new drugs with help from Darwinian principles ScienceDaily: Latest Science News urn:uuid:98236a80-e1a3-22e1-ca7d-60b3dcc0e944 Mon, 06 Dec 2021 10:29:58 -0600 Our body must constantly defend itself against bacteria and viruses. It generates millions of different antibodies, which are selected to recognise the enemy and trigger the best possible immune response. Scientists use these antibodies to for therapeutic purposes to target proteins and disrupt their harmful. However, identifying the small molecules that will form the basis of the drug is a long and tedious process. Chemists have now developed a technique inspired by the theory of Darwinian evolution: amplifying the best combinations and generating diversity allows biology to find solutions to new problems.

Big gaps in quest to sequence genomes of all animals ScienceDaily: Latest Science News urn:uuid:7d4dd73d-e562-9192-1762-2faa59ccb107 Mon, 06 Dec 2021 08:06:20 -0600 Efforts to sequence the genomes of the world's animals tend to focus on those that most resemble humans with the work conducted almost entirely in the Global North, according to new analysis. 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.

ALS therapy should target brain, not just spine ScienceDaily: Latest Science News urn:uuid:83dc3318-020a-3ffd-9ff3-3b1aff2a6696 Thu, 02 Dec 2021 18:11:46 -0600 The brain is indeed a target for treating ALS (amyotrophic lateral sclerosis), scientists have discovered. This flips a long-standing belief the disease starts in the spinal motor neurons and any therapy would need to target the spine as the key focus. The new study shows the brain degenerates early in ALS, sends warning signals and shows defects very early in the disease. Degeneration of brain motor neurons is not merely a byproduct of the spinal motor neuron degeneration, as had been previously thought.
