NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis
Advanced Science, EarlyView.In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...

Superimposition of ribbed moraines on a palaeo‐ice‐stream bed: implications for ice stream dynamics and shutdown [PDF]
Earth Surface Processes and Landforms, 2008 AbstractThe sediments and landforms preserved on palaeo‐ice‐stream beds can provide important information about their subglacial conditions and flow mechanisms, and the processes accompanying their shutdown. In this paper, detailed observations of an intriguing subglacial landform assemblage of ribbed moraines superimposed on glacial lineations on the ...

ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction
Advanced Science, EarlyView.Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

The impact of temperature and crystal orientation fabric on the dynamics of mountain glaciers and ice streams [PDF]
, 2020 Streaming ice accounts for a major fraction of global ice flux, yet we cannot yet fully explain the dominant controls on its kinematics. In this contribution, we use an anisotropic full-Stokes thermomechanical flow solver to characterize how mechanical ...

Advanced Science, EarlyView.Intermittent fasting reshapes the gut microbiota in diabetic cardiomyopathy, restoring Akkermansia muciniphila and the microbiota‐associated metabolite 1‐methyl‐L‐histidine. This shift is linked to improved cardiac lipid homeostasis, reduced lipid peroxidation, and attenuated myocardial injury, highlighting a gut microbiota–metabolite–lipid axis in ...

Greenland Ice Sheet and rising sea level in a worst-case climate change scenario [PDF]
, 2004 P(論文)Models that simulate sheet flow in the Greenland Ice Sheet balance forces at gridpoints in the map plan, which allows only a slow response to changes in climate forcing. A holistic approach to modeling allows a rapid response that takes place in ice

Advanced Science, EarlyView.A cytokinin pathway transcription factor, RR2b, was artificially selected during soybean domestication and improvement based on its differential transcriptional activity, which correlates with ATT repeat polymorphisms in its promoter. RR2b balances yield and defense by fine‐tuning its expression level and offers a promising target for decoupling trade ...

The last glaciation of Shetland : local ice cap or invasive ice sheet? [PDF]
, 2013 Issue ISBN: 978-82-92-39488-5 This work is supported by the Carnegie Trust for the Universities of ScotlandThe question of whether the Shetland Islands were covered by an ice cap or by an ice sheet during the last glacial cycle (40–10 ka) remains ...
