摘要:Cement can be reused by including it as a component of steel recycling. This opens the way to an industrial partnership that improves the use of materials and lowers carbon emissions - but only if waste resources are well managed.

摘要:Time spent outdoors is the best defence against rising rates of short-sightedness, but scientists are searching for other ways to reverse the troubling trend.

摘要:Cement production causes 7.5% of global anthropogenic CO2 emissions, arising from limestone decarbonation and fossil-fuel combustion(1-3). Current decarbonation strategies include substituting Portland clinker with supplementary materials, but these mainly arise in emitting processes, developing alternative binders but none yet promises scale, or adopting carbon capture and storage that still releases some emissions(4-8). However, used cement is potentially an abundant, decarbonated feedstock....

摘要:Higher plants survive terrestrial water deficiency and fluctuation by arresting cellular activities (dehydration) and resuscitating processes (rehydration). However, how plants monitor water availability during rehydration is unknown. Although increases in hypo-osmolarity-induced cytosolic Ca2+ concentration (HOSCA) have long been postulated to be the mechanism for sensing hypo-osmolarity in rehydration(1,2), the molecular basis remains unknown. Because osmolarity triggers membrane tension and...

摘要:Certain neurons encode memories of events that occurred in specific physical locations known as place fields. Chickadees show patterns of neuronal activity that are specific to locations of hidden food but independent of place fields.

摘要:Climate warming induces shifts from snow to rain in cold regions1, altering snowpack dynamics with consequent impacts on streamflow that raise challenges to many aspects of ecosystem services2-4. A straightforward conceptual model states that as the fraction of precipitation falling as snow (snowfall fraction) declines, less solid water is stored over the winter and both snowmelt and streamflow shift earlier in season. Yet the responses of streamflow patterns to shifts in snowfall fraction rem...

摘要:In somatic tissue differentiation, chromatin accessibility changes govern priming and precursor commitment towards cellular fates(1-3). Therefore, somatic mutations are likely to alter chromatin accessibility patterns, as they disrupt differentiation topologies leading to abnormal clonal outgrowth. However, defining the impact of somatic mutations on the epigenome in human samples is challenging due to admixed mutated and wild-type cells. Here, to chart how somatic mutations disrupt epigenetic...
