摘要：Dirac fluids-interacting systems obeying particle-hole symmetry and Lorentz invariance-are among the simplest hydrodynamic systems; they have also been studied as effective descriptions of transport in strongly interacting Dirac semimetals. Direct experimental signatures of the Dirac fluid are elusive, as its charge transport is diffusive as in conventional metals. In this paper, we point out a striking consequence of fluctuating relativistic hydrodynamics: The full counting statistics (FCS) o...

摘要：Reducing meat and dairy intake has been identified as a necessary strategy for mitigating the high environmental impacts food systems are currently having on climate change, biodiversity loss associated with land- use changes, and freshwater use. Having a choice of dedicated meat and milk replacements available to consumers can help in the transition toward more plant- based diets, but concerns about nutritional and health impacts and high costs can impede uptake. Here, we conduct a multicrite...

摘要：The design of synthetic soft matter capable of emulating the complex behaviors of living organisms, such as sensing and adapting to their environment, remains an important challenge in developing biomimetic materials. Functionalized hydrogels are ideal candidates for such materials since they are highly responsive to their environment and can be operated in water. In this work, we investigate a hybrid bonding hydrogel composed of peptide amphiphile supramolecular nanofibers covalently attached...

摘要：Polymer film dielectrics are highly favored for capacitive energy storage due to the inherent advantages of high breakdown strength, low dielectric loss, and ease of processing. High- density renewables conversion and harsh- condition electrification further emphasize the need for high- temperature, high- k polymers. A unique design strategy is developed to augment high- temperature polyolefins with improved dielectric constant, via the integration of phenyl pendants hanging off the rigid bicy...

摘要：The toxic effects of C9orf72- derived arginine-rich dipeptide repeats (R-DPRs) on cellular stress granules in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia remain unclear at the molecular level. Stress granules are formed through the switch of Ras GTPase- activating protein- binding protein 1 (G3BP1) by RNA from a closed inactive state to an open activated state, driving the formation of the organelle by liquid-liquid phase separation (LLPS). We show that R-DPRs bind G3BP1 a ...

摘要：Climate warming can alleviate temperature and nutrient constraints on tree growth in boreal regions, potentially enhancing boreal productivity. However, in permafrost environments, warming also disrupts the physical foundation on which trees grow, leading to leaning trees or drunken forests. Tree leaning might reduce radial growth, undermining potential benefits of warming. Here, we found widespread radial growth reductions in southern latitude boreal forests since the 1980s. At mid latitudes,...

摘要：A large body of research documents the barriers faced by first-generation, low-income (FGLI) students as hidden minorities on elite college campuses. Although existing studies show brief psychological interventions can help mitigate some of these obstacles, universities are investing in more intensive interventions that try to both shift mindsets and mitigate structural disadvantages in FGLI students' academic preparation. In collaboration with the administrators at a highly selective universi...

摘要：The high emissions intensity of terrestrial animal source food (TASF) and projected increasing demand in low- and middle- income countries (LMIC) have spurred interest in the development of animal- free alternatives and manufactured food items that aim to substitute for meat, milk, and eggs with the promise of reduced environmental impact of producing food. The developing world is the source of 75% of global emissions from ruminants and will house 86% of the world's human population by 2050. T...
