Gemini North’s MAROON-X instrument finds evidence for four mini-Earth exoplanets around our famous cosmic neighbor Barnard’s Star For a century, astronomers have been studying Barnard’s Star in the hope of finding planets around it. First discovered by E. E. Barnard at Yerkes Observatory in 1916, it is the nearest single star system to Earth [1]. Barnard’s Star is classified as a red dwarf — low-mass stars that often host closely-packed planetary systems, often with multiple rocky planets. Red dwarfs are extremely numerous in the Universe, so scientists…
Study links genetics, vision and neural processing to mating behavior in Heliconius butterflies A simple neural change alters mating preferences in male butterflies, aiding rapid behavioral evolution, Nicholas VanKuren and Nathan Buerkle at the University of Chicago, US, and colleagues, report March 11th in the open-access journal PLOS Biology. Heliconius are a group of tropical butterflies known for their wide variety of wing patterns and colors, which act as a warning to predators. Because wing coloration is crucial for their…
As major changes continue for our planet’s climate, scientists are concerned about how plants will grow and adapt. Researchers in the MSU-DOE Plant Research Laboratory, or PRL, Sharkey lab are studying changes in plant metabolism that occur when plants are grown in high light, high CO2 (HLHC) conditions. They found that under these conditions, plants photosynthesize more, which can lead to larger plants, and potentially larger crop yields. However, there are tradeoffs; scientists also found that plants lose carbon under…
Understanding children’s subjective experiences through color As a child, did it ever occur to you that your perception of color differed from that of others? It’s quite common to have this thought, but it turns out that the human color experience may be more universal than we previously believed. In psychology and neuroscience, the relationship between subjective experience, such as how we perceive color, and physical brain activity has remained an unresolved problem. Furthermore, due to their limited language abilities,…
Scientists treat seeds with cold plasma, measure impact on plant growth, insect defense The same substance that paints the sky with the Northern Lights also appears to enhance plant growth and insect defense, according to a new study. Food science and entomology researchers from the Arkansas Agricultural Experiment Station teamed up to harness plasma and measure its effects on rice seed. The project began after Mahfuzur Rahman, assistant professor of food science, acquired a machine that produces cold plasma. Known…
University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was just less than 300 million years old – just 2% of its current age. What Does the James Webb Telescope Tell Us About the Universe? Ever since the launch of the James Webb Telescope, it has sailed across the starry universe, discovering galaxies formed around thirteen billion years ago—almost the inception of time itself! It possesses advanced infrared capabilities, much more evolved…
Scripps Research scientists created a stable form of carnosic acid, observing greater memory function and other disease improvements in mice. The herb rosemary has long been linked with memory: “There’s rosemary, that’s for remembrance,” says Ophelia in Shakespeare’s Hamlet. So it is fitting that researchers would study a compound found in rosemary and sage—carnosic acid—for its impact on Alzheimer’s disease. In the disease, which is the leading cause of dementia and the sixth leading cause of death in the US,…
Physics professor J. Ping Liu helps boost nation’s energy security and advance toward a world-class magnet research hub University of Texas at Arlington physics Professor J. Ping Liu has won the 2025 Hill Prize in Physical Sciences for pioneering new ways to design magnets that power high-tech devices. Awarded by the Texas Academy of Medicine, Engineering, Science and Technology (TAMEST) and Lyda Hill Philanthropies, the prize recognizes groundbreaking innovations with the potential for real-world impact. Dr. Liu shares the award as co-principal…
Metabolic dysfunction-associated fatty liver disease (MAFLD) has become a growing global health concern, affecting millions worldwide. This complex liver disorder ranges from simple steatosis to more severe forms, including metabolic dysfunction-associated steatohepatitis (MASH), which may progress to fibrosis, cirrhosis, and even liver cancer. The latest insights into transcription factors provide a deeper understanding of the disease’s progression and potential therapeutic interventions. Transcription factors are critical proteins that regulate gene expression, playing a pivotal role in controlling key processes such as…
Researchers have manufactured Super-invar Fe64-Ni32-Co4 (wt %) alloy through wire-arc additive manufacturing(WAAM), revealing the association between the micro-structure and the value of the G (the temperature gradient)/R (the solidification rate) during the deposition process, and achieving the coefficient of thermal expansion (CTE) of 0.265×10-6K-1 from 20℃ to 100℃. Published in Advanced manufacturing, the findings provide a reference for the fast fabrication of super-invar alloy components through WAAM, which promotes the applications of super-invar alloy in aerospace. Super-invar alloy, distinguished by…
CAM is proposed to highlight the class-related activation regions for an image classification network, where feature positions related to the specific object class are activated and have higher scores while other regions are suppressed and have lower scores. For specific visual tasks, CAM can be used to infer the object bounding boxes in weakly-supervised object location(WSOL) and generate pseudo-masks of training images in weakly-supervised semantic segmentation (WSSS). Therefore, obtaining the high-quality CAM is very important to improve the recognition performance…
Researchers from Osaka University find that in immune tissues, plasma cells that express certain proteins are more likely to migrate to the bone marrow, where they help create long-lasting antibody responses Vaccine effectiveness relies on creating a strong antibody response that can be reactivated to fight future infections. Now, researchers from Japan report that antibody-producing cells are destined for longevity from the moment they are born. In a recent study published in the Journal of Experimental Medicine, a multi-institutional research…
Computer simulations reveal how water separates into high-density and low-density liquids Water is unique. It is one of the only substances that can exist in nature as a solid, liquid and gas at the same time under ambient conditions (think of solid ice over a pond, which is liquid underneath while storm clouds float overhead). It is also one of the only substances whose solid form is less dense than its liquid — this is why ice floats. Now scientists…
Lung cancer remains one of the leading causes of cancer-related mortality, with lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) representing the most prevalent subtypes of non-small cell lung cancer (NSCLC). Despite their classification under the same umbrella, these two forms of lung cancer exhibit distinct genetic landscapes, therapeutic targets, and treatment responses. Recent advancements in next-generation gene sequencing have identified key driver genes that differentiate LUAD and LUSC, influencing their respective clinical management approaches. LUAD is frequently associated…
An ambitious project led by Vanderbilt University Medical Center investigators aims to use artificial intelligence technologies to generate antibody therapies against any antigen target of interest. VUMC has been awarded up to $30 million from the Advanced Research Projects Agency for Health (ARPA-H) to build a massive antibody-antigen atlas, develop AI-based algorithms to engineer antigen-specific antibodies, and apply the AI technology to identify and develop potential therapeutic antibodies. ARPA-H is an agency within the U.S. Department of Health and Human…
