  摘要：The enantioselective construction of small-ring carbocycles provides organic chemists with an enduring challenge1. Despite their commercial importance, enantioselective synthetic routes towards alkylidenecyclopropanes, a class of small-ring carbocycles, remain underdeveloped2,3. Alkylidenecyclopropanes can be converted into cyclopropanes, a common feature in drug molecules (for example, Nirmatrelvir 1)4, as well as both naturally occurring and synthetic agrochemicals (for example, permethrin 2...

• Stronger El Niños reduce tropical forest arthropod diversity and function AI翻译

  摘要：There is ongoing debate about the vulnerability of arthropods to climate change1,2. Long-term impacts of climate change on arthropod communities could manifest through short-term weather patterns3. Arthropods in the tropics are hyper-diverse4,5 and contribute many crucial ecosystem functions6,7, but are comparatively less studied than in temperate regions1,8,9. Tropical forest arthropods and the functions that they provide may be vulnerable to intensified El Ni & ntilde;o events under climate ...

  摘要：Bipedalism is a human-defining trait1, 2-3. It is made possible by the familiar, bowl-shaped pelvis, whose short, wide iliac blades curve along the sides of the body to stabilize walking and support internal organs and a large-brained, broad-shouldered baby4, 5-6. The ilium changes compared with living primates are an evolutionary novelty7. However, how this evolution came about remains unknown. Here, using a multifaceted histological, comparative genomic and functional genomic approach, we id...

  摘要：The emergence of animal phyla, each with their unique body plan, was a rapid event in the history of animal life, yet its genomic underpinnings are still poorly understood1. Here we investigate at the genomic, regulatory and cellular levels, the origin of one of the most distinctive animal phyla, the chaetognaths, whose organismal characteristics have historically complicated their phylogenetic placement2,3. We show that these characteristics are reflected at the cell-type level by the express...
