  摘要：Mechanical metamaterials exhibit interesting properties such as high stiffness at low density1-3, enhanced energy absorption3,4, shape morphing5-7, sequential deformations8-11, auxeticity12-14 and robust waveguiding15,16. Until now, metamaterial design has primarily relied on geometry, and materials nonlinearities such as viscoelasticity, fracture and plasticity have been largely left out of the design rationale. In fact, plastic deformations have been traditionally seen as a failure mode and ...

  摘要：Continuous attractors are an emergent property of neural population dynamics that have been hypothesized to encode continuous variables such as head direction and eye position1-4. In mammals, direct evidence of neural implementation of a continuous attractor has been hindered by the challenge of targeting perturbations to specific neurons within contributing ensembles2,3. Dynamical systems modelling has revealed that neurons in the hypothalamus exhibit approximate line-attractor dynamics in ma...

• Electric cars could save billions in health-care costs AI翻译
  作者：Klopper, Abigail
  摘要：Improving air quality by discontinuing combustion-engine vehicles would slash health-care costs in the United States, but the projected savings in rural areas depend on how the replacements are powered.

• Global conservation priorities for island plant diversity AI翻译
  作者：Givnish, Thomas J.
  作者单位：University of Wisconsin System; University of Wisconsin Madison
  摘要：How much of Earth's plant diversity is distributed across islands, and how might this affect conservation efforts? It emerges that islands contain a disproportionately large share of global plant diversity and endangered species.
• 'Do-it-yourself' data storage on DNA paves way to simple archiving system AI翻译
  作者：Imburgia, Carina; Nivala, Jeff
  作者单位：University of Washington; University of Washington Seattle
  摘要：Data can be stored on DNA, but the methods involve time-consuming DNA synthesis and must be done by experts. A user-friendly approach has been developed that potentially solves these problems.

  摘要：Biobanks aim to improve our understanding of health and disease by collecting and analysing diverse biological and phenotypic information in large samples. So far, biobanks have largely pursued a population-based sampling strategy, where the individual is the unit of sampling, and familial relatedness occurs sporadically and by chance. This strategy has been remarkably efficient and successful, leading to thousands of scientific discoveries across multiple research domains, and plans for the n...
