Over the last sixty ears, Singapore has expanded its land footprint over twenty-five percent by reclaiming land from the sea. Its outsized demand for sand to resource these projects has rendered regional sand markets precarious, and successive countries have banned sand exports to Singapore. Nevertheless, the Singapore government has committed to spending $SG one billion (US$ 767 million) a year until 2100 to mitigate sea level rise. While this includes a range of strategies, from improving drainage infrastructure to exploring adaptive solutions, in the main this involves reclaiming vast amounts of land from the sea to act as a bulwark against rising tides. These plans for resilience will be examined through the spectre of Long Island, a proposed project that will act as a barrier against sea level rise and incorporate nature-based solutions that are emblematic of resilience fetishism, all the while obscuring the more foundational element of this resilience, which is sand that will be obtained through granular arbitrage.

Regional sea level rise has been regarded a key factor in understanding of climate change impact to coastal communities. As a vulnerable island to sea level rise and storm surges, the province of Prince Edward Island (PEI) in Canada lacks sufficient long-term island-wide historic record of sea level data. This has become a major challenge for further studies on coastal environments and climate change adaptation.

Extracellular vesicles (EVs) play a crucial role in diagnosis and treatment, yet obtaining highly purified EVs from complex biological samples is often hindered by nanoscale contaminants. In this work, considering the charge-to-size characteristics of EVs, a circular multicavity electrophoresis (CME) with gradient pore size distribution was constructed in the gradient electric field to realize the isolation and preparation of EVs. By the gradient gel sieving effect, small cell debris, EVs, and proteins in biological samples were gradually separated.

For a given solar elevation, the levels of solar ultraviolet radiation at the Earth's surface are determined by the amounts of ozone, aerosols, and clouds, as well as by the reflectivity of the surface. Here, we study the evolution of these factors for three selected decades in the period 1950-2100 using results from simulations with Earth-System models (ESMs) participating in the 6 phase of the Coupled Model Intercomparison Project (CMIP6). The simulations for the future are based on three Shared Socioeconomic Pathways: SSP1-2.

Solute carrier family 23 (SLC23) mediates cellular uptake of ascorbic acid, a crucial antioxidant protecting organisms against oxidative stress. Despite advances in understanding SLC23 in mammals, its physiological roles in bivalves remain poorly understood. Notably, euryhaline bivalves exhibit a significant expansion and positive selection of SLC23, highlighting the need for deeper investigation.
