  摘要：The electronic properties of crystals can be manipulated by superimposing spatially periodic electric, magnetic or structural modulations. Long-wavelength modulations incommensurate with the atomic lattice are particularly interesting1, exemplified by recent advances in two-dimensional (2D) moir & eacute; materials2,3. Bulk van der Waals (vdW) superlattices4-8 hosting 2D interfaces between minimally disordered layers represent scalable bulk analogues of artificial vdW heterostructures and pres...

  摘要：From sequences of speech sounds1,2 or letters3, humans can extract rich and nuanced meaning through language. This capacity is essential for human communication. Yet, despite a growing understanding of the brain areas that support linguistic and semantic processing4-12, the derivation of linguistic meaning in neural tissue at the cellular level and over the timescale of action potentials remains largely unknown. Here we recorded from single cells in the left language-dominant prefrontal cortex...
• Your reagent is past its use-by date. Should you bin it? AI翻译
  作者：Kwon, Diana
  摘要：Some products are perfectly fine to use after their expiration date - if quality-control tests check out.
• The search for superconductivity just got wider AI翻译
  作者：Xie, Weiwei
  作者单位：Michigan State University
  摘要：Compounds containing copper have long been targeted in the search for high-temperature superconductivity, but experiments performed at extreme pressures suggest that nickel-based materials might also be candidates.

  摘要：In all organisms, regulation of gene expression must be adjusted to meet cellular requirements and frequently involves helix-turn-helix (HTH) domain proteins(1). For instance, in the arms race between bacteria and bacteriophages, rapid expression of phage anti-CRISPR (acr) genes upon infection enables evasion from CRISPR-Cas defence; transcription is then repressed by an HTH-domain-containing anti-CRISPR-associated (Aca) protein, probably to reduce fitness costs from excessive expression(2-5)....
• Measuring gravitational attraction with a lattice atom interferometer AI翻译

  摘要：Despite being the dominant force of nature on large scales, gravity remains relatively elusive to precision laboratory experiments. Atom interferometers are powerful tools for investigating, for example, Earth's gravity1, the gravitational constant2, deviations from Newtonian gravity3-6 and general relativity7. However, using atoms in free fall limits measurement time to a few seconds8, and much less when measuring interactions with a small source mass2,5,6,9. Recently, interferometers with at...
• Animal research is not always king: researchers should explore the alternatives AI翻译
  作者：[Anonymous]
  摘要：Technological advances can reduce the numbers of laboratory animals used in studies - but they need to be carefully validated.
