Cutting-edge observations of Centaurus Cluster shine new light on evolving universe The XRISM collaboration have discovered flows of hot gas in the core of the Centaurus Cluster. By comparing state-of-the-art X-ray measurements from the XRISM satellite with numerical simulations, they showed this is evidence for collisions between galaxy clusters, causing gas inside to “slosh”. This solves the longstanding mystery of how cluster cores stay hot, and sheds light on how our universe continues to evolve. Astronomers have long envisioned how…
A recent paper published in the journal Engineering delves into the future of artificial intelligence (AI) beyond large language models (LLMs). LLMs have made remarkable progress in multimodal tasks, yet they face limitations such as outdated information, hallucinations, inefficiency, and a lack of interpretability. To address these issues, researchers explore three key directions: knowledge empowerment, model collaboration, and model co-evolution. Knowledge empowerment aims to integrate external knowledge into LLMs. This can be achieved through various methods, including integrating knowledge into training objectives,…
Novel study paints more accurate picture of extinct, gigantic shark The megalodon has long been imagined as an enormous great white shark, but new research suggests that perception is all wrong. The study finds the prehistoric hunter had a much longer body—closer in shape to a lemon shark or even a large whale. The study team, which included researchers from University of California, Riverside and across the globe, used a novel approach to estimate the shark’s total body length, moving…
National Poll: 2 in 5 parents wish the government was doing more to prevent a bird flu outbreak; 1 in 3 have taken action to protect their family against it With soaring egg prices and ongoing bird flu headlines, many parents are uncertain about the risks and facts surrounding the virus, a national poll suggests. Most parents say they don’t know if there have been cases of bird flu in their state, and less than half feel that they are…
UChicago Pritzker School of Molecular Engineering research created inorganic and polymer battery electrolytes simultaneously, with potential applications across chemistry Creating battery electrolytes – the component that carries the charged particles back and forth between a battery’s two terminals – has always been a tradeoff. Solid-state inorganic electrolytes move the particles extremely efficiently, but being solid and inorganic means they’re also brittle, hard to work with and difficult to connect seamlessly with the terminals. Polymer electrolytes are a dream to work…
Butterflies are disappearing in the United States. All kinds of them. With a speed scientists call alarming, and they are sounding an alarm. A sweeping new study published in Science for the first time tallies butterfly data from more than 76,000 surveys across the continental United States. The results: between 2000 and 2020, total butterfly abundance fell by 22% across the 554 species counted. That means that for every five individual butterflies within the contiguous U.S. in the year 2000,…
Andrew Barto and Richard Sutton recognized as pioneers of reinforcement learning ACM, the Association for Computing Machinery, today named Andrew G. Barto and Richard S. Sutton as the recipients of the 2024 ACM A.M. Turing Award for developing the conceptual and algorithmic foundations of reinforcement learning. In a series of papers beginning in the 1980s, Barto and Sutton introduced the main ideas, constructed the mathematical foundations, and developed important algorithms for reinforcement learning—one of the most important approaches for creating…
Declining student performance tied to life skills gaps, not just pandemic The impact of the COVID-19 pandemic on student performance is well known, but four years after the pandemic, scores in college classes are not returning to their pre-pandemic levels. A University of Mississippi study might point to an answer. In a study published in a special issue of the Educational Sciences journal, three Ole Miss researchers found that student performance scores started a downward trend following COVID-19. Dozens of…
A new Cochrane review has found evidence that music-based therapy may benefit people living with dementia, particularly by improving symptoms of depression. Dementia is a collective term for progressive degenerative brain syndromes that affect memory, thinking, behaviour and emotion. Alzheimer’s Disease International reported that there were 55 million people with dementia worldwide in 2019, a figure predicted to increase to 139 million by 2050. While some medicines are available, the therapeutic use of music is considered a relatively simple and…
EP’s cutting-edge instruments and international collaboration drive new discoveries in transient and multi-messenger astronomy The Science White Paper for the Einstein Probe (EP) mission has been published in Science China: Physics, Mechanics & Astronomy. This mission, spearheaded by the Chinese Academy of Sciences (CAS) in collaboration with the European Space Agency (ESA), the Max Planck Institute for Extraterrestrial Physics (MPE), and the French National Centre for Space Studies (CNES), is poised to advance the field of time-domain and X-ray astronomy…
Hyperspectral imaging and AI can identify individuals using blood vessels in palms Hyperspectral imaging is a technology that detects slight differences in color to pinpoint the characteristics and conditions of an object. While a normal camera creates images using red, green, and blue, a hyperspectral camera can obtain over 100 images in the visible to near-infrared light range in a single shot. As a result, hyperspectral imaging can obtain information that the human eye cannot see. Specially Appointed Associate Professor…
The hydrogel has a unique structure, making it the first to combine strength and flexibility with self-healing capabilities. We all encounter gels in daily life – from the soft, sticky substances you put in your hair, to the jelly-like components in various foodstuffs. While human skin shares gel-like characteristics, it has unique qualities that are very hard to replicate. It combines high stiffness with flexibility, and it has remarkable self-healing capabilities, often healing completely within 24 hours after injury. Until…
Bigger, tastier tomatoes and eggplants could soon grace our dinner plates thanks to Johns Hopkins scientists who have discovered genes that control how large the fruits will grow. The research—led by teams at Johns Hopkins University and Cold Spring Harbor Laboratory—could lead to the development of new varieties of heirloom tomatoes and eggplants, including those that help support agriculture in areas around the world where local varieties are currently too small for large-scale production. Findings were published in the journal Nature. “Once…
Study findings could improve understanding of aging and obesity The body’s internal clock doesn’t just dictate when we sleep — it also determines how quickly our muscles heal. A new Northwestern Medicine study in mice, published today in Science Advances, suggests that muscle injuries heal faster when they occur during the body’s natural waking hours. The findings could have implications for shift workers and may also prove useful in understanding the effects of aging and obesity, said senior author Clara Peek, assistant…
A new seismic study of Singapore could guide urban growth and renewable energy development in the coastal city nation, where 5.6 million residents live within an area of 734 square kilometers. The study, published in Seismological Research Letters, identifies areas with increased risk of ground shaking and a possible reservoir for geothermal energy production, as well as a glimpse at Singapore’s tectonic history. Jiayuan Yao of China University for Geosciences and colleagues analyzed teleseismic data captured by a few permanent…
Scientists at St. Jude Children’s Research Hospital used positron emission tomography (PET) with edaravone, a drug used to treat ALS, to detect oxidative stress Positron emission tomography (PET) is a nuclear imaging technique used to diagnose conditions such as cancer. An innovative advance from scientists at St. Jude Children’s Research Hospital is enhancing the technique’s ability to check for signs of neurological disease. The researchers repurposed the drug edaravone, an antioxidant used to treat amyotrophic lateral sclerosis (ALS), as a probe to…
