Published Paving the way to extremely fast, compact computer memory



Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.
Published Microplastic pollution increases sea foam height and stability



Researchers examine the specific impacts of microplastics on the geophysics of sea foam formation in the critical zone where water meets air in the top layer of the ocean. They devised two simulations for their work -- a column filled with sea water injected with air and a laboratory-scale breaking wave channel to test the impacts of wave height on sea foam in the surface microlayer -- and tested their effects on sea foam formation, stability, and duration.
Published Weather experts discover new effect of storm -- in a teacup



A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.
Published Additional taxes vs. water quotas: Study compares the most effective system to manage water consumption in agriculture



A new study finds that the proportional allocation of water, and not additional taxes on the resource, is more effective from the point of view of those engaged in agriculture.
Published A new neural network makes decisions like a human would



Researchers are training neural networks to make decisions more like humans would. This science of human decision-making is only just being applied to machine learning, but developing a neural network even closer to the actual human brain may make it more reliable, according to the researchers.
Published Producing hydrogen and fertilizer at the same time



This new concept could allow the needs of previously separate industries to be combined: the production of hydrogen and the production of fertilizer.
Published Loss of oxygen in lakes and oceans a major threat to ecosystems, society, and planet



Oxygen is a fundamental requirement of life, and the loss of oxygen in water, referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, researchers describe how ongoing deoxygenation presents a major threat to the stability of the planet as a whole.
Published Study examines urban forests across the United States



Tree-planting campaigns have been underway in the United States, especially in cities, as part of climate mitigation efforts given the many environmental benefits of urban forests. But a new study finds that some areas within urban forests in the U.S., may be more capable than trees growing around city home lawns in adapting to a warmer climate.
Published When to trust an AI model



A new technique enables huge machine-learning models to efficiently generate more accurate quantifications of their uncertainty about certain predictions. This could help practitioners determine whether to trust the model when it is deployed in real-world settings.
Published High and low tide cause low and high methane fluxes



Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the seafloor can be just easily three times as much or as little, depending on the tide, according to a new study.
Published Neural networks made of light



Scientists propose a new way of implementing a neural network with an optical system which could make machine learning more sustainable in the future. In a new paper, the researchers have demonstrated a method much simpler than previous approaches.
Published How risk-averse are humans when interacting with robots?



How do people like to interact with robots when navigating a crowded environment? And what algorithms should roboticists use to program robots to interact with humans? These are the questions that a team of mechanical engineers and computer scientists sought to answer in a recent study.
Published Scientists call for 'major initiative' to study whether geoengineering should be used on glaciers



Scientists have released a landmark report on glacial geoengineering -- an emerging field studying whether technology could halt the melting of glaciers and ice sheets as climate change progresses.
Published New solutions to keep drinking water safe as pesticide use skyrockets worldwide



Water scientists have proposed a more effective method of removing organic pesticides from drinking water, reducing the risk of contamination and potential health problems.
Published Targeted home systems to remove PFAS more cost-effective than system-wide solutions



PFAS, the potentially cancer-causing chemicals known as 'forever chemicals', have become an increasing concern in home drinking water. Solutions to reduce the risk of exposure range from mandated municipal-level water treatment to under-the-sink home treatment systems. But are consumers willing to foot the bill for an additional treatment system to help municipalities meet new federal drinking water regulations? Researchers found that they are, if it helps reduce the risk and fits their budget.
Published Could lead overcome reverse current and advance a green hydrogen economy?



Researchers developed a catalyst that enhances the stability of alkaline water electrolysis systems.
Published The Gulf Stream is wind-powered and could weaken from climate change



New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published Researchers introduce generative AI for databases



Researchers have developed an easy-to-use tool that enables someone to perform complicated statistical analyses on tabular data using just a few keystrokes. Their method combines probabilistic AI models with the programming language SQL to provide faster and more accurate results than other methods.
Published Building materials for water-rich planets in the early solar system



Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These planetesimals continually supplied building materials for planets -- also for the Earth, whose original material contained little water. The Earth received its actual water through planetesimals, which emerged at low temperatures in the outer solar system, as shown by computational models carried out by an international research teach with participation by earth scientists.
Published Detecting defects in tomorrow's technology



New research offers an enhanced understanding of common defects in transition-metal dichalcogenides (TMDs) -- a potential replacement for silicon in computer chips -- and lays the foundation for etching smaller features.
