Ammonia (NH3) is one of the most widely produced chemicals in the world, with a production of over 187 million tons in 2020. About 85% of it is used to produce nitrogenous fertilizers, while the rest is used for refining petroleum, manufacturing a wide range of other chemicals, and creating synthetic fibers such as nylon. However, all this comes at a high energy cost. Currently, most of the ammonia is produced using the conventional Haber-Bosch process, which requires combining nitrogen and hydrogen at high temperatures (400-450°C) and pressures (200 atmospheres). As a result, scientists ...

Several dietary patterns, including the DASH-style eating plan, Mediterranean, pescatarian and vegetarian eating patterns, received top ratings for aligning with the Association’s dietary guidance. A few eating patterns, including Paleo and ketogenic diets, contradict the Association’s guidance and did not rank as heart-healthy eating patterns. The statement suggests opportunities for dietary research and interventions to promote health equity, recognizing the importance of social determinants of health in shaping dietary ...

Life in the ocean’s “twilight zone” could decline dramatically due to climate change, new research suggests. The twilight zone (200m to 1,000m deep) gets very little light but is home to a wide variety of organisms and billions of tonnes of organic matter. The new study warns that climate change could cause a 20-40% reduction in twilight zone life by the end of the century. And in a high-emissions future, life in the twilight zone could be severely depleted within 150 years, with no recovery for ...

In the summer of 2022, over 20,000 excess deaths across Spain, France, Germany and Great Britain were suggested to have been linked to extremely hot weather. In the context of global warming where climate models point to the fact that extreme heat waves are likely to increase both in frequency and magnitude, preventive measures and adequate communication of dangerous conditions take on special relevance. In a Brief Communication published in npj Climate and Atmospheric Science, researchers from the Barcelona Institute for Global Health (ISGlobal), a centre supported ...

The vast majority of AI models used in medicine today are “narrow specialists,” trained to perform one or two tasks, such as scanning mammograms for signs of breast cancer or detecting lung disease on chest X-rays.  But the everyday practice of medicine involves an endless array of clinical scenarios, symptom presentations, possible diagnoses, and treatment conundrums. So, if AI is to deliver on its promise to reshape clinical care, it must reflect that complexity of medicine and do so with high fidelity, says Pranav ...

New research has revealed children’s physical activity in the UK has largely returned to pre-pandemic levels – but children are still more sedentary during the week.  The study, led by the University of Bristol, found that by summer last year 41% of children were meeting the national recommended physical activity guidelines of an hour on average of moderate to vigorous physical activity daily. Although this shows an improvement from the immediate aftermath of the COVID-19 pandemic, when little more than a third (37%) were meeting this target, it means the majority of children were still ...

The World Health Organization’s draft drinking water guidance for the two most well-studied per- and polyfluoroalkyl substances (PFAS) exhibit a “striking and inappropriate disregard of the best available science,” according to former directors of the U.S. EPA’s Office of Science and Technology and the National Institute of Environmental Health Sciences (NIEHS). In a viewpoint for the peer-reviewed journal Environmental Science & Technology, Betsy Southerland and Linda Birnbaum strongly recommend ...

Researchers have developed a new mining technique which uses microbes to recover metals and store carbon in the waste produced by mining. Adopting this technique of reusing mining waste, called tailings, could transform the mining industry and create a greener and more sustainable future. Tailings are a by-product of mining. They are the fine-grained waste materials left after extracting the target ore mineral, which are then stacked and stored. This method is called dry-stack tailing. Over time, mining practices have evolved and become more efficient. But the climate crisis and rising demand for critical minerals require the development of new ore removal and ...

About one-third of our lives are spent at work, and the relationships we build there can have personal and professional benefits. But a majority of workers indicate difficulty connecting with co-workers socially, especially in the new landscape of remote and hybrid work arrangements.

Sand filters are commonly applied in drinking water treatment and can efficiently remove suspended solids, organic matter, and microorganisms from source water. During the process, particulate matter and microbes can attach to filter sands and develop a thick biofilm in both rapid and slow sand filters. To prevent clogging and restore pollutant removal efficiency, backwashing using air, water, or a combination of both is usually required for sand filters. However, backwashing can induce a loss in biomass, thus decreasing the pollutant ...
