Published Fishy mystery of marine reptile solved



The identity of a prehistoric marine reptile has finally been revealed after experts discovered that some of its remains actually belonged to fish.
Published Blood sausages and yak milk: Bronze Age cuisine of Mongolian nomads unveiled



Bronze cauldrons were used by the inhabitants of the Mongolian steppe around 2,700 years ago to process animal blood and milk. This is shown by a protein analysis of archaeological finds from this period.
Published Uptake of tire wear additives by vegetables grown for human consumption



Car tires contain hundreds of chemical additives that can leach out of them. This is how they end up in crops and subsequently in the food chain. Researchers have now detected these chemical residues in leafy vegetables for the first time. Although the concentrations were low, the evidence was clear, a finding that is also known for drug residues in plant-based foods.
Published Babies use 'helpless' infant period to learn powerful foundation models, just like ChatGPT



Babies' brains are not as immature as previously thought, rather they are using the period of postnatal 'helplessness' to learn powerful foundation models similar to those underpinning generative Artificial Intelligence, according to a new study.
Published A cracking discovery -- eggshell waste can recover rare earth elements needed for green energy



A collaborative team of researchers has made a cracking discovery with the potential to make a significant impact in the sustainable recovery of rare earth elements (REEs), which are in increasing demand for use in green energy technologies. The team found that humble eggshell waste could recover REES from water, offering a new, environmentally friendly method for their extraction.
Published Climate change will make ozone pollution worse: Here's how



A new study finds climate change is likely to make upward spikes of ozone at ground level worse by 2050, which could result in many parts of the United States falling out of compliance with air quality standards and increasing risks to public health.
Published Electrified charcoal 'sponge' can soak up CO2 directly from the air



Researchers have developed a low-cost, energy-efficient method for making materials that can capture carbon dioxide directly from the air. Researchers used a method similar to charging a battery to instead charge activated charcoal, which is often used in household water filters.
Published 'Missing' early sea sponges discovered



Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.
Published 'Weird' new planet retained atmosphere despite nearby star's relentless radiation



A rare exoplanet that should have been stripped down to bare rock by its nearby host star's intense radiation somehow grew a puffy atmosphere instead -- the latest in a string of discoveries forcing scientists to rethink theories about how planets age and die in extreme environments. Nicknamed 'Phoenix' for its ability to survive its red giant star's radiant energy discovered planet illustrates the vast diversity of solar systems and the complexity of planetary evolution -- especially at the end of stars' lives.
Published Study reveals how 'forever chemicals' may impact heart health in older women



New research has linked multiple types of per- and polyfluoroalkyl substances (PFAS, also known as 'forever chemicals') with increased risk of cardiovascular diseases in postmenopausal women. Specifically, the study reveals how PFAS chemicals interact with pro-inflammatory pathways in older women, providing potential explanations for the increased risk.
Published Giant viruses found on Greenland ice sheet



Giant viruses found on the Greenland ice sheet probably regulate the growth of snow algae on the ice by infecting them. Knowing how to control these viruses could help us reduce the rate of ice-melt.
Published A new way of designing auxetic materials



Auxetics defy common sense, widening when stretched and narrowing when compressed. Researchers have now made the process of using them much easier, paving the way for new types of auxetic products -- from better sneaker insoles to blast-resilient buildings.
Published Using AI to decode dog vocalizations



Have you ever wished you could understand what your dog is trying to say to you? Researchers are exploring the possibilities of AI, developing tools that can identify whether a dog's bark conveys playfulness or aggression.
Published Small, but smart: How symbiotic bacteria adapt to big environmental changes



Lucinid clams, inconspicuous inhabitants of the seafloor and one of the most diverse group of animals in the ocean, rely on symbiotic bacteria for their survival. Researchers now reveal the evolutionary journey of these tiny tenants. Faced with a drastically changing environment following the closure of the Isthmus of Panama, they acquired new metabolic skills to enable their own survival. Understanding the adaptive strategies of bacteria provides insight into their potential responses to challenging environmental changes, such as those caused by human activities.
Published Some countries could meet their total electricity needs from floating solar panels



Floating solar photovoltaic panels could supply all the electricity needs of some countries, new research has shown. The researchers calculated the daily electrical output for floating photovoltaics (FPV) on nearly 68,000 lakes and reservoirs around the world, using available climate data for each location.
Published Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK



A team of palaeontologists has discovered a fossil of a gigantic flying reptile from the Jurassic period with an estimated wingspan of more than three metres -- making it one of the largest pterosaurs ever found from that era.
Published Unraveling the physics of knitting



A team used experiments and simulations to quantify and predict how knit fabric response can be programmed. By establishing a mathematical theory of knitted materials, the researchers hope that knitting -- and textiles in general -- can be incorporated into more engineering and manufacturing applications.
Published Key nutrients help plants beat the heat



Scientists have discovered some of the molecular mechanisms controlling how plants -- including important crops like soybean and rice -- will respond to rising global temperatures, finding higher temperatures make root systems grow faster, but sustaining this increased growth speed depends on high levels of nitrogen and phosphorus in the soil. The discoveries point to the necessity of nitrogen and phosphorus-rich soil to promote crop growth and create nutritious crops, in addition to aiding a mission to create more resilient crops in the face of climate change.
Published A technique for more effective multipurpose robots



MIT researchers developed a technique to combine robotics training data across domains, modalities, and tasks using generative AI models. They create a combined strategy from several different datasets that enables a robot to learn to perform new tasks in unseen environments.
Published Mapping the seafloor sediment superhighway



A new scientific model is giving researchers an unprecedented, global look at the activities of clams, worms, and other invertebrate animals that burrow at the bottom of the ocean.
