Semiconductor industry waste is typically seen as a costly disposal problem and an environmental hazard. But what if this waste could be transformed into a valuable resource? In an exciting development, researchers have unveiled an eco-friendly method to extract rare metals from semiconductor waste. This innovative approach not only recovers precious tungsten but also assesses its economic viability, offering a sustainable solution for waste management in the tech industry.

As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties.

Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest that aluminous phase B could explain seismic velocity anomalies in the Earth's mantle transition region and uppermost lower mantle.

Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.

Researchers at University of Galway have developed a new, portable technology for on-the-spot testing of water quality to detect one of the most dangerous types of bacteria. Ireland regularly reports the highest crude incidence rates of the pathogen Shiga toxigenic Escherichia coli -- STEC for short -- in Europe over the recent years.

In 2023, roughly 60,000 firework shells exploded above Manhattan's East River as part of Macy's Fourth of July show. The resulting air pollutant levels were many times higher in the hours after the display than those seen when smoke from a Canadian wildfire had blanketed the area a month before, according to the results of a new study.

Groundwater is a vital resource, sustaining plants and ecosystems, ensuring agricultural production and serving as a core component of drinking water supplies. However, climate change and anthropogenic pressures can threaten groundwater availability, especially in southwestern Europe. This threat was evaluated by a research team using multidecadal data from more than 12,000 groundwater wells in Portugal, Spain, France, and Italy. The surprising finding: Groundwater levels are not declining everywhere as widely believed, but primarily in semi-arid regions with intensive agriculture and frequent droughts. Declines are also observed in temperate regions associated with large urban areas. The authors conclude that, with suitable management practices, groundwater can be utilized sustainably.

Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for particle physics research.

Why does the universe contain matter and (virtually) no antimatter? Scientists have achieved an experimental breakthrough in this context. It can contribute to measuring the mass and magnetic moment of antiprotons more precisely than ever before -- and thus identify possible matter-antimatter asymmetries. They have developed a trap, which can cool individual antiprotons much more rapidly than in the past.

Much of the water in the West is transported across vast geographical areas by large infrastructure projects known as interbasin water transfers. Two of these projects in particular make up 85% of all energy-related greenhouse gas emissions associated with U.S. interbasin transfers -- one in Arizona and the other in California -- according to the new research.

Scientists have hypothesized that moir excitons -- electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns -- may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits, it has not been possible to focus light enough in measurements, causing optical interference from many moir excitons. To solve this, researchers have developed a new method of reducing these moir excitons to measure the quantum coherence time and realize quantum functionality.
