摘要:Recent marine heatwaves have had pervasive effects on marine ecosystems, from declines in primary production to die-offs of top predators. Seabird mortalities are often observed in association with heatwaves, but population impacts are not well understood. In this work, we report the rapid mortality of approximately half of Alaska's common murre (Uria aalge) population in response to an extreme marine heatwave. Between the 7-year period before (2008-2014) and after (2016-2022) the heatwave, mu...

摘要:The global ocean covers 71% of Earth's surface, yet the seafloor is poorly charted compared with land, the Moon, Mars, and Venus. Traditional ocean mapping uses ship-based soundings and nadir satellite radar altimetry-one limited in spatial coverage and the other in spatial resolution. The joint NASA-CNES (Centre National d'Etudes Spatiales) Surface Water and Ocean Topography (SWOT) mission uses phase-coherent, wide-swath radar altimetry to measure ocean surface heights at high precision. We s...

摘要:Bacteriophages are the most abundant and phylogenetically diverse biological entities on Earth, yet the ecological mechanisms that sustain this extraordinary diversity remain unclear. In this study, we discovered that phage diversity consistently outstripped the diversity of their bacterial hosts under simple experimental conditions. We assembled and passaged dozens of diverse phage communities on a single, nonevolving strain of Escherichia coli until the phage communities reached equilibrium....

摘要:The advancement in semiconductor technology through the integration of more devices on a chip has reached a point where device scaling alone is no longer an efficient way to improve the device performance. One issue lies in the interconnects connecting the transistors, in which the resistivity of metals increases exponentially as their dimensions are scaled down to match those of the transistors. As a result, the total signal processing delay is dominated by the resistance-capacitance (RC) del...
