• Scientists discover first algae that can fix nitrogen - thanks to a tiny cell structure AI翻译
  作者：Wong, Carissa
  摘要：A newly discovered 'organelle' that converts nitrogen gas into a useful form could pave the way for engineered plants that require less fertilizer.

  摘要：OSCA/TMEM63 channels are the largest known family of mechanosensitive channels1-3, playing critical roles in plant4-7 and mammalian8,9 mechanotransduction. Here we determined 44 cryogenic electron microscopy structures of OSCA/TMEM63 channels in different environments to investigate the molecular basis of OSCA/TMEM63 channel mechanosensitivity. In nanodiscs, we mimicked increased membrane tension and observed a dilated pore with membrane access in one of the OSCA1.2 subunits. In liposomes, we ...

• An exploration of how the insect-wing hinge functions AI翻译
  作者：Deora, Tanvi
  摘要：The hinge enables insects to control their wing movements, but how it works is hard to study. Multidisciplinary research, using imaging and machine-learning methods, now sheds light on the mechanism that underlies its operation.

• Stripped-envelope supernova light curves argue for central engine activity AI翻译
  作者：Rodriguez, Osmar; Nakar, Ehud; Maoz, Dan
  作者单位：Tel Aviv University
  摘要：The luminosity of stripped-envelope supernovae, a common type of stellar explosion, is believed to be mainly driven by the radioactive decay of the nickel synthesized in the explosion and carried in its ejecta. Additional possible energy sources have been previously suggested1-5, in which the two most observationally based results have been from a comparison of the observed time-weighted luminosity with the inferred radioactive power1 and from a comparison of the light curves with particular t...

  摘要：Extensive efforts have been undertaken to combine superconductivity and the quantum Hall effect so that Cooper-pair transport between superconducting electrodes in Josephson junctions is mediated by one-dimensional edge states1-6. This interest has been motivated by prospects of finding new physics, including topologically protected quasiparticles7-9, but also extends into metrology and device applications10-13. So far it has proven challenging to achieve detectable supercurrents through quant...
• Digital colloid-enhanced Raman spectroscopy by single-molecule counting AI翻译

  摘要：Quantitative detection of various molecules at very low concentrations in complex mixtures has been the main objective in many fields of science and engineering, from the detection of cancer-causing mutagens and early disease markers to environmental pollutants and bioterror agents1-5. Moreover, technologies that can detect these analytes without external labels or modifications are extremely valuable and often preferred6. In this regard, surface-enhanced Raman spectroscopy can detect molecula...
