  摘要：Gills and mammalian ears bear little resemblance, yet examination of gene regulation reveals that key supportive cartilage tissue arises from similar embryonic cells guided by an evolutionarily conserved genetic program.

  摘要：The Spo11 complex catalyses the formation of DNA double-strand breaks (DSBs), initiating meiotic recombination-a process that is essential for fertility and genetic diversity1,2. Although the function of Spo11 has been known for 27 years, previous efforts to reconstitute DSB formation in vitro have been unsuccessful. Here we biochemically characterize the mouse SPO11-TOP6BL protein complex, and show that this complex cleaves DNA and covalently attaches to the 5 ' terminus of DNA breaks in vitr...

  摘要：Topological defects and disorder counteract each other1, 2, 3, 4-5. Intuitively, disorder is considered detrimental, requiring efforts to mitigate its effects in conventional topological photonics6, 7, 8-9. We propose a counter-intuitive approach that exploits a real-momentum topological photonic crystal that harnesses real-space disorder to generate a Pancharatnam-Berry phase10,11, without disrupting the momentum-space singularity originating from bound states in the continuum12. This methodo...
