Published Scientists harness quantum microprocessor chips for revolutionary molecular spectroscopy simulation
(via sciencedaily.com) Original source Engineering researchers have successfully developed a quantum microprocessor chip for molecular spectroscopy simulation of actual large-structured and complex molecules.
Published Peering into the mind of artificial intelligence to make better antibiotics
(via sciencedaily.com) Original source Artificial intelligence (AI) has exploded in popularity as of late. But just like a human, it's hard to read an AI model's mind. Explainable AI (XAI) could help us do just that by providing justification for a model's decisions. And now, researchers are using XAI to scrutinize predictive AI models more closely, which could help make better antibiotics.
Published Forest loss intensifies climate change by increasing temperatures and cloud level, which leads to decrease of water
(via sciencedaily.com) Original source Researchers report that deforestation during the last two decades induced a higher warming and cloud level rise than that caused by climate change, which threatens biodiversity and water supply in African montane forests.
Published Preservation of organic carbon in the ocean floor
(via sciencedaily.com) Original source The preservation of organic carbon in marine sediments has long been a key question remaining unclear in understanding the long-term carbon cycling on Earth. Recently, scientists have gained new insights into the dynamic cycling of iron-bound organic carbon in subseafloor sediments.
Published Nitrogen interventions as a key to better health and robust ecosystems
(via sciencedaily.com) Original source An international research team combined multidisciplinary methods to evaluate how nitrogen interventions could improve air quality and reduce nitrogen deposition. Their study found that interventions, such as improving fuel combustion conditions, increasing agricultural nitrogen use efficiency, and reducing food loss and waste, could significantly lower premature deaths attributed to air pollution, crop losses, and ecosystems risks.
Published Decoding mysterious seismic signals
(via sciencedaily.com) Original source Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface.
Published Detecting machine-generated text: An arms race with the advancements of large language models
(via sciencedaily.com) Original source Today, many commercial tools claim to be highly successful at detecting machine-generated text, with up to 99% accuracy, but are these claims too good to be true? RAID, the Robust AI Detection benchmark, which shows that most detectors are easily fooled, setting a new bar for AI detection to clear.
Published Scottish and Irish rocks confirmed as rare record of 'snowball Earth'
(via sciencedaily.com) Original source The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.
Published As human activities expand in Antarctica, scientists identify crucial conservation sites
(via sciencedaily.com) Original source Establishing Key Biodiversity Areas in the Southern Ocean will be vital for safeguarding the ecosystem from the impact of human activities, researchers say.
Published Robot planning tool accounts for human carelessness
(via sciencedaily.com) Original source A new algorithm may make robots safer by making them more aware of human inattentiveness. In computerized simulations of packaging and assembly lines where humans and robots work together, the algorithm developed to account for human carelessness improved safety by about a maximum of 80% and efficiency by about a maximum of 38% compared to existing methods.
Published Warming waters and nutrient overload: A dangerous combination threatening our rivers and lakes
(via sciencedaily.com) Original source New international research found that food webs are becoming less complex in warmer, nutrient-rich waters.
Published Advancing modular quantum information processing
(via sciencedaily.com) Original source A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.
Published New brain-computer interface allows man with ALS to 'speak' again
(via sciencedaily.com) Original source A new brain-computer interface translates brain signals into speech with up to 97 percent accuracy. Researchers implanted sensors in the brain of a man with severely impaired speech due to amyotrophic lateral sclerosis (ALS). The man was able to communicate his intended speech within minutes of activating the system.
Published Tropical Atlantic mixing rewrites climate pattern rules
(via sciencedaily.com) Original source Changes in the Atlantic Ocean's mixed layer are the primary force behind the Atlantic Multidecadal Variability (AMV).
Published Smart fabric converts body heat into electricity
(via sciencedaily.com) Original source Researchers have developed a smart fabric that can convert body heat and solar energy into electricity, potentially enabling continuous operation with no need for an external power source. Different sensors monitoring temperature, stress, and more can be integrated into the material.
Published How air-powered computers can prevent blood clots
(via sciencedaily.com) Original source A new, air-powered computer sets off alarms when certain medical devices fail. The invention is a more reliable and lower-cost way to help prevent blood clots and strokes -- all without electronic sensors.
Published In subdivided communities cooperative norms evolve more easily
(via sciencedaily.com) Original source Researchers simulated social norms with a supercomputer. Their findings contribute to a deeper understanding of the evolution of social norms and their role in fostering cooperative behavior.
Published Climate change raised the odds of unprecedented wildfires in 2023-24
(via sciencedaily.com) Original source Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
Published Say 'aah' and get a diagnosis on the spot: is this the future of health?
(via sciencedaily.com) Original source A computer algorithm has achieved a 98% accuracy in predicting different diseases by analyzing the color of the human tongue. The proposed imaging system can diagnose diabetes, stroke, anemia, asthma, liver and gallbladder conditions, COVID-19, and a range of vascular and gastrointestinal issues, according to new research.
Published Changing food consumers' choices may help cut greenhouse gases
(via sciencedaily.com) Original source Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets.
