Published Ancient ocean slowdown warns of future climate chaos
(via sciencedaily.com) Original source When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.
Published Quantum data assimilation: A quantum leap in weather prediction
(via sciencedaily.com) Original source Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve data assimilation on quantum computers, significantly reducing the computation time. The findings of the study have the potential to advance NWP systems and will inspire practical applications of quantum computers for advancing data assimilation.
Published No bones about it: 100-million-year-old bones reveal new species of pterosaur
(via sciencedaily.com) Original source New research has identified 100-million-year-old fossilized bones discovered in western Queensland as belonging to a newly identified species of pterosaur, which was a formidable flying reptile that lived among the dinosaurs.
Published Scientists unlock secrets of how archaea, the third domain of life, makes energy
(via sciencedaily.com) Original source An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.
Published Peers crucial in shaping boys' confidence in math skills
(via sciencedaily.com) Original source Boys are good at math, girls not so much? A study has analyzed the social mechanisms that contribute to the gender gap in math confidence. While peer comparisons seem to play a crucial role for boys, girls' subjective evaluations are more likely to be based on objective performance.
Published Tiny new species of great ape lived in Germany 11 million years ago
(via sciencedaily.com) Original source Ancient apes in Germany co-existed by partitioning resources in their environment, according to a new study.
Published Digital babies created to improve infant healthcare
(via sciencedaily.com) Original source Researchers have created digital babies to better understand infants' health in their critical first 180 days of life. The team created 360 advanced computer models that simulate the unique metabolic processes of each baby.
Published Tiny roundworms carve out unique parasitic niche inside pseudoscorpion's protective covering
(via sciencedaily.com) Original source In a parasitic first, a Baltic amber specimen has revealed that millions of years ago tiny worms known as nematodes were living inside of and feeding on the outer protective layer of pseudoscorpions.
Published Fishy mystery of marine reptile solved
(via sciencedaily.com) Original source The identity of a prehistoric marine reptile has finally been revealed after experts discovered that some of its remains actually belonged to fish.
Published 'Missing' early sea sponges discovered
(via sciencedaily.com) Original source 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 Using AI to decode dog vocalizations
(via sciencedaily.com) Original source 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 New model allows a computer to understand human emotions
(via sciencedaily.com) Original source Researchers have developed a model that enables computers to interpret and understand human emotions, utilizing principles of mathematical psychology. In the future, the model can help the computer to adapt its own behavior and guide an irritated or anxious user in different ways. The implications of such technology are profound, offering a glimpse into a future where computers are not merely tools, but empathetic partners in user interaction.
Published Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK
(via sciencedaily.com) Original source 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 The embryo assembles itself
(via sciencedaily.com) Original source Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.
Published Children's visual experience may hold key to better computer vision training
(via sciencedaily.com) Original source A novel, human-inspired approach to training artificial intelligence (AI) systems to identify objects and navigate their surroundings could set the stage for the development of more advanced AI systems to explore extreme environments or distant worlds, according to new research.
Published AI-controlled stations can charge electric cars at a personal price
(via sciencedaily.com) Original source As more and more people drive electric cars, congestion and queues can occur when many people need to charge at the same time. A new study shows how AI-controlled charging stations, through smart algorithms, can offer electric vehicle users personalized prices, and thus minimize both price and waiting time for customers. But the researchers point to the importance of taking the ethical issues seriously, as there is a risk that the artificial intelligence exploits information from motorists.
Published 'Ugly' fossil places extinct saber-toothed cat on Texas coast
(via sciencedaily.com) Original source This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.
Published AI saving humans from the emotional toll of monitoring hate speech
(via sciencedaily.com) Original source A team of researchers have developed a new machine-learning method that detects hate speech on social media platforms with 88 per cent accuracy, saving employees from hundreds of hours of emotionally damaging work.
Published Origins of 'Welsh dragons' finally exposed by experts
(via sciencedaily.com) Original source A large fossil discovery has helped shed light on the history of dinosaurs in Wales.
Published Musankwa sanyatiensis, a new dinosaur from Zimbabwe
(via sciencedaily.com) Original source Fossils found on the shoreline of Lake Kariba in Zimbabwe represent a completely new dinosaur species. This remarkable find, named Musankwa sanyatiensis, marks only the fourth dinosaur species named from Zimbabwe.
