• UK university departments on the brink as higher-education funding crisis deepens AI翻译
  作者：Leeming, Jack
  摘要：As a new academic year dawns, international competition, government policies and inflationary pressures could be pushing some universities to the brink of bankruptcy.
• A drug-free prescription for pain AI翻译
  作者：Brown, Carolyn
  摘要：Non-invasive, non-pharmacological approaches such as virtual-reality therapy and yoga can help to relieve chronic pain.

  摘要：Primary production in the sunlit surface ocean is regulated by the supply of key nutrients, primarily nitrate, phosphate and iron (Fe), required by phytoplankton to fix carbon dioxide into biomass1-3. Below the surface ocean, remineralization of sinking organic matter rapidly regenerates nutrients, and microbial metabolism in the upper mesopelagic 'twilight zone' (200-500 m) is thought to be limited by the delivery of labile organic carbon4,5. However, few studies have examined the role of nut...

  摘要：When laser radiation is skilfully applied, atoms and molecules can be cooled(1-3), allowing the precise measurements and control of quantum systems. This is essential for the fundamental studies of physics as well as practical applications such as precision spectroscopy(4-7), ultracold gases with quantum statistical properties(8-10) and quantum computing. In laser cooling, atoms are slowed to otherwise unattainable velocities through repeated cycles of laser photon absorption and spontaneous e...
• Why do we crumble under pressure? Science has the answer AI翻译

  摘要：Study links this phenomenon to the brain region that controls movement. Study links this phenomenon to the brain region that controls movement.
• The gut microbiome and chronic pain AI翻译
  作者：Watson, Clare
  摘要：Pain from conditions such as endometriosis could be alleviated if the gut's resident bacteria can be understood and tamed.
• Structural insights into the high-affinity IgE receptor FcεRI complex AI翻译

  摘要：Immunoglobulin E (IgE) plays a pivotal role in allergic responses(1,2). The high-affinity IgE receptor, Fc epsilon RI, found on mast cells and basophils, is central to the effector functions of IgE. Fc epsilon RI is a tetrameric complex, comprising Fc epsilon RI alpha, Fc epsilon RI beta and a homodimer of FcR gamma (originally known as Fc epsilon RI gamma), with Fc epsilon RI alpha recognizing the Fc region of IgE (Fc epsilon) and Fc epsilon RI beta-FcR gamma facilitating signal transduction(...
• Mitochondrial complex I promotes kidney cancer metastasis AI翻译
  作者：[Anonymous]
  摘要：Most kidney cancers are metabolically dysfunctional(1-4), but how this dysfunction afects cancer progression in humans is unknown. We infused C-13-labelled nutrients in over 80 patients with kidney cancer during surgical tumour resection. Labelling from [U-C-13]glucose varies across subtypes, indicating that the kidney environment alone cannot account for all tumour metabolic reprogramming. Compared with the adjacent kidney, clear cell renal cell carcinomas (ccRCCs) display suppressed labellin...
