  摘要：Photoluminescent molecules and nanomaterials have potential applications as active waveguides, but such a use has often been limited by high optical losses and complex fabrication processes. We explored ligand-protected metal nanoclusters (LPMNCs), which can have strong, stable, and tunable emission, as waveguides. Two alloy LPMNCs, Pt1Ag18 and AuxAg19-x (7 <= x <= 9), were synthesized and structurally determined. Crystals of both exhibited excellent optical waveguide performance, with optical...
• Generative approach to research integrity AI翻译

  摘要：It's been a bad few weeks for public perceptions of research integrity, as multiple cases at elite universities have received wide news coverage. Francesca Gino, a scientist at Harvard University, is in a legal dispute over whether data in newly retracted papers about dishonesty were manipulated; she is now suing Harvard and the researchers who surfaced the alleged problems. Likewise, Duke University is investigating published work by scientist Daniel Ariely. Johns Hopkins University may initi...

  摘要：Skin color, one of the most diverse human traits, is determined by the quantity, type, and distribution of melanin. In this study, we leveraged the light-scattering properties of melanin to conduct a genome-wide screen for regulators of melanogenesis. We identified 169 functionally diverse genes that converge on melanosome biogenesis, endosomal transport, and gene regulation, of which 135 represented previously unknown associations with pigmentation. In agreement with their melanin-promoting f...

  摘要：Indigenous communities shoulder a disproportionate burden of ill health compounded by climate change. In Australia, the oldest surviving cultures have adapted their ecological knowledge over millennia and across climatic ages. However, European colonization has severely curtailed Indigenous peoples' ability to adjust to climate change. An effective response to the climate crisis requires decolonizing processes to reform our relationship with the planet. From an Australian Indigenous perspectiv...
