  摘要：Most stars in today's Universe reside within spheroids, which are bulges of spiral galaxies and elliptical galaxies1,2. Their formation is still an unsolved problem3, 4-5. Infrared/submillimetre-bright galaxies at high redshifts6 have long been suspected to be related to spheroid formation7, 8, 9, 10, 11-12. Proving this connection has been hampered so far by heavy dust obscuration when focusing on their stellar emission13, 14-15 or by methodologies and limited signal-to-noise ratios when look...

  摘要：C4 photosynthesis is used by the most productive plants on the planet, and compared with the ancestral C3 pathway, it confers a 50% increase in efficiency1. In more than 60 C4 lineages, CO2 fixation is compartmentalized between tissues, and bundle-sheath cells become photosynthetically activated2. How the bundle sheath acquires this alternate identity that allows efficient photosynthesis is unclear. Here we show that changes to bundle-sheath gene expression in C4 leaves are associated with the...
• Shifting sands threaten flood-mitigation measures AI翻译

  摘要：Climate change and urbanization are exacerbating the effects of flooding. A close look at a Nepalese river reveals that efforts to reduce the impact of floods must consider the geomorphic changes that occur during these extreme events.

  摘要：Gene-edited stem cells can be used in regenerative therapies to treat diverse genetic diseases. Tracking the output of these cells over time reveals a commitment to lineages that meet disease-specific needs.

  摘要：The bone marrow microenvironment is a critical regulator of haematopoietic stem cell self-renewal and fate1. Although it is appreciated that ageing, chronic inflammation and other insults compromise bone marrow function and thereby negatively affect haematopoiesis2, it is not known whether different bone compartments exhibit distinct microenvironmental properties and functional resilience. Here we use imaging, pharmacological approaches and mouse genetics to uncover specialized properties of b...
• A subcortical feeding circuit linking an interoceptive node to jaw movement AI翻译

  摘要：The brain processes an array of stimuli, enabling the selection of appropriate behavioural responses, but the neural pathways linking interoceptive inputs to outputs for feeding are poorly understood1-3. Here we delineate a subcortical circuit in which brain-derived neurotrophic factor (BDNF)-expressing neurons in the ventromedial hypothalamus (VMH) directly connect interoceptive inputs to motor centres, controlling food consumption and jaw movements. VMHBDNF neuron inhibition increases food i...
