  摘要：Antarctica harbors many distinctive features of life, yet much about the diversity and functioning of Antarctica's life remains unknown. Evolutionary histories and functional ecology are well understood only for vertebrates, whereas research on invertebrates is largely limited to species descriptions and some studies on environmental tolerances. Knowledge on Antarctic vegetation cover showcases the challenges of characterizing population trends for most groups. Recent community-level microbial...
• Overwriting an instinct: Visual cortex instructs learning to suppress fear responses AI翻译

  摘要：Fast instinctive responses to environmental stimuli can be crucial for survival but are not always optimal. Animals can adapt their behavior and suppress instinctive reactions, but the neural pathways mediating such ethologically relevant forms of learning remain unclear. We found that posterolateral higher visual areas (plHVAs) are crucial for learning to suppress escapes from innate visual threats through a top-down pathway to the ventrolateral geniculate nucleus (vLGN). plHVAs are no longer...

  摘要：Some plants have massive sex-linked regions. To test hypotheses about their evolution, we sequenced the genome of Silene latifolia, in which giant heteromorphic sex chromosomes were first discovered in 1923. It has long been known that the Y chromosome consists mainly of a male-specific region that does not recombine with the X chromosome and carries the sex-determining genes and genes with other male functions. However, only with a whole Y chromosome assembly can candidate genes be validated ...
