Access to clean water is being strained as the human population increases and contamination impacts freshwater sources. Devices currently in development that clean up dirty water using sunlight can only produce up to a few gallons of water each day. But now, researchers in ACS Central Science report how loofah sponges inspired a sunlight-powered porous hydrogel that could potentially purify enough water to satisfy someone's daily needs -- even when it's cloudy.

Researchers have made a groundbreaking discovery in the field of thermal radiation, uncovering a new method for generating spinning thermal radiation in a controlled and efficient manner using artificially structured surfaces, known as metasurfaces.

Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.

Researchers have theorized a new mechanism to generate high-energy 'quantum light', which could be used to investigate new properties of matter at the atomic scale.

Energy-efficient ways of cooling buildings and vehicles will be required in a changing climate. Researchers have now shown that electrical tuning of passive radiative cooling can be used to control temperatures of a material at ambient temperatures and air pressure.

New developments for achieving structural coloring through plasma irradiation of graphite can reduce the reliance upon harmful color dyes. Colors achieved by plasma irradiation are completely erasable and can be manipulated using time exposed to the plasma irradiation, intensity of the irradiation and the thickness of the graphite layer applied. The application of plasma-structural coloring aims to lessen the environmental toll typical adverse dyes have and combat them with the technology surrounding structural colors.

Las Vegas, with its rapid urbanization and desert landscape, is highly vulnerable to flooding. For this reason, flood managers have built an extensive system of drainage ditches and detention basins to protect the public. Now, a new study shows how intentional engineering and urban development are interacting with climate change to alter the timing and intensity of flood risk.

A new modelling study shows that the Seychelles and other islands in the western Indian Ocean are not responsible for most of the plastic waste that accumulates on their beaches. Indonesia, India, and Sri Lanka were found to be the main sources of land-based plastic debris. The Seychelles also accumulate significant amounts of plastic debris of marine origin from fisheries and shipping lanes. • The results highlight the urgent need for a legally-binding Global Plastics Treaty and greater enforcement of regional policies to reduce plastic waste.

Supporters of the large-scale Mississippi River sediment diversions currently being planned by the Louisiana Coastal Protection and Restoration Authority got a boost to their case recently when scientists published an analysis of two existing freshwater diversions on the state's coastline, one of which shows a significant amount of land having formed over the past 17 years.

Satellite observations have revealed that weak seismic ground shaking can trigger powerful landslide acceleration -- even several years after a significant earthquake.

Scientists have found a new and better way to use remote sensing to understand where coastal dead zones are and predict changes.

On March 11, 2011, multiple catastrophes in Japan were triggered by the Great East Japan Earthquake, including the nuclear accident at the Fukushima Daiichi Nuclear Power Plant. This event, also known as the 3/11 disaster, is what is known as a compound disaster. Now that over a decade has passed since this event, researchers are investigating how to prevent the next compound disaster.

Subduction zones, where one tectonic plate slides beneath another, produce the most devastating seismic, volcanic, and landslide hazards on the planet. A new report presents an ambitious plan to make major advances in understanding subduction zone hazards by bringing together a diverse community of scientists in a long-term collaborative effort, deploying new instrumentation in subduction zones, and developing more sophisticated and accurate models.

A devastating fire followed by an intense rainstorm triggered mudslides in Southern California in 2018 that claimed 23 lives. New findings elucidate the physics behind the deadly disaster that may inform predictive models of future mudslides.

Rapidly evolving floods are a major and growing hazard worldwide. Currently, their onset and evolution is hard to identify using existing systems. However, seismic sensors already in place to detect earthquakes could be a solution to this problem. Researchers show that a seismometer can sense a flood, such as the devastating one that hit Germany in July 2021, up to 1.5 km away. This could act as an early warning to save lives and lessen damage. They also found that being able to measure the 'seismic footprint' of the flood provides information on its magnitude, velocity and trajectory in real time, which could be used for future flood protection.

Researchers recently published a study looking at land use changes from the past and the importance of taking factors such as socio-economic development and the dynamic nature of coastal environments into consideration to make these areas more resilient to climate change.

A new large-scale analysis of hillslope connectivity at the continental scale was recently published. The study gives new understanding of mechanisms that determine how effectively hillslopes drive floods and landslides, as well as promote the presence of wetlands.
