  摘要：Photoenzymes are light-powered biocatalysts that typically rely on the excitation of cofactors or unnatural amino acids for their catalytic activities1,2. A notable natural example is the fatty acid photodecarboxylase, which uses light energy to convert aliphatic carboxylic acids to achiral hydrocarbons3. Here we report a method for the design of a non-natural photodecarboxylase based on the excitation of enzyme-bound catalytic intermediates, rather than reliance on cofactor excitation4. Imini...
• If the Nobel Prizes were designed today, what would change? AI翻译
  作者：Ball, Philip
  摘要：The awards' strict constraints often prompt frustration - if these prestigious prizes were created for the twenty-first century, how would they be different?
• How to Fix Health Data for People with Asian and Pacific Islander Heritage AI翻译
  作者：Madhusoodanan, Jyoti
  摘要：Separating medical data from culturally distinct Asian American, Native Hawaiian and Pacific Islander (AANHPI) groups can improve health outcomes.

• How much energy does it take to make a baby? Researchers are rethinking what they know AI翻译
  作者：Wong, Carissa
  摘要：Across the animal kingdom, models have vastly underestimated the energy costs of reproduction.

  摘要：Early amniote development is highly self-organized, capable of adapting to interference through local and long-range cell-cell interactions. This process, called embryonic regulation1, has been well illustrated in experiments on avian embryos, in which subdividing the epiblast disk into different parts not only redirects cell fates to eventually form a complete and well-proportioned embryo at its original location, but also leads to the self-organization of additional, fully formed embryos2,3 ...

• Electronic rotons and Wigner crystallites in a two-dimensional dipole liquid AI翻译

  摘要：A key concept proposed by Landau to explain superfluid liquid helium is the elementary excitation of quantum particles called rotons1-8. The irregular arrangement of atoms in a liquid leads to the aperiodic dispersion of rotons, which played a pivotal role in understanding fractional quantum Hall liquids (magneto-rotons)9,10 and the supersolidity of Bose-Einstein condensates11-13. Even for a two-dimensional electron or dipole liquid, in the absence of a magnetic field, the repulsive interactio...
