Astronomers using NASA’s James Webb Space Telescope (JWST) have created the most detailed map yet of the cosmic web, the vast structure that connects galaxies throughout the universe. A research team led by researchers at the University of California, Riverside traced this vast network back to just about 1 billion years after the birth of the universe. The cosmic web is the giant skeletal framework of the universe. It is made up of filaments and sheets of dark matter and gas surrounding a huge, mostly empty region of space known as the void. Together, these structures form the large-scale structure…

NASA’s Hubble Space Telescope has captured the most detailed visible-light images ever taken of the largest known protoplanetary disk surrounding a young star. This massive structure is far more chaotic and turbulent than astronomers expected, with huge swaths of gas and dust spread high above and below the disk. Even more unusual is that the longest filament-like structure is only found on one side. This discovery is astrophysical journalprovides scientists with rare observations of how planets form in extreme space environments and highlights Hubble’s continued role in space exploration. Huge planet-forming disk never seen before The system, known as IRAS…

INDIGO Biosciences today announced the launch of its transrepression assay service. This expands the company’s cell-based reporter assay capabilities for drug discovery teams studying pathway crosstalk, selective regulation, and transcription factor-mediated gene silencing. This new service capability provides researchers with additional functional approaches to characterize the activity of compounds across nuclear receptor signaling and inflammatory pathways, and complements INDIGO’s existing receptor activation and pathway reporter assay services. As part of this service, INDIGO Biosciences now supports GR/NF-κB transrepression studies, allowing customers to assess the interaction between glucocorticoid receptor signaling and NF-κB-driven transcriptional activity. in vitro Reporter assay format. Trans-repression is…

Researchers at the Jülich Supercomputing Center and NVIDIA have achieved a major milestone in quantum computing by fully simulating the first 50-qubit universal quantum computer. This achievement was achieved using JUPITER, Europe’s first exascale supercomputer, which was officially launched at the Jülich Movement Center last September. This achievement surpasses the previous record of 48 qubits, set in 2019 by Jülich scientists using Japan’s K computer. In addition to setting new benchmarks, this breakthrough highlights the enormous capabilities of JUPITER and could accelerate the development of future quantum algorithms and technologies. Why quantum simulation is important Quantum computer simulations play an…

Preclinical research at the University of California, Riverside sheds light on a phenomenon that has been observed for years but is little understood. In other words, despite cannabis’ well-known tendency to increase appetite, regular cannabis users tend to be lower in weight and have a lower risk of developing type 2 diabetes. A team led by Nicholas V. DiPatrizio, a professor of biomedical science in the UCR School of Medicine, set out to investigate this apparent contradiction. Cannabis is typically associated with increased food intake known as “munchies,” but population studies consistently show that regular users have an improved metabolic…

Scientists have long known that the immune system plays an important role in aging. As people age, their response to vaccinations decreases, their risk of infection increases, and their levels of inflammation increase. A new study led by researchers at UCLA Health used routine laboratory test results to measure not only immune reactivity but how it directly relates to long-term mortality in patients. why is it important The results were announced on April 27th. Gero science It gives researchers a tool to study immune function in large patient populations using a tuberculosis screening test called the interferon gamma release assay…

Getting enough exercise is important for healthy aging, but new research suggests muscle strength may play an equally important role. A large study led by researchers at the University at Buffalo found that older, physically fit women had a significantly lower risk of death, even when physical activity levels, cardiovascular health, and inflammation were taken into account. The survey results are JAMA network openResearchers followed participants for eight years and found that women with stronger grip strength and faster chair-to-stand test times were more likely to live longer. Muscle strength is associated with lower mortality rates This study focused on…

The maintenance of the physiological function of the eye as a highly differentiated sensory organ relies on tight metabolic regulation. The intramitochondrial tricarboxylic acid (TCA) cycle serves as a core pathway for ocular energy metabolism, providing essential metabolic substrates and reducing equivalents for corneal homeostasis and retinal phototransmission. However, significant scientific questions remain. The question is, are there significant heterogeneities in energy utilization between different anatomical tissues of the eye? Furthermore, how does biological sex modulate the ocular metabolic profile through different biological pathways? Previous studies have mainly employed relative quantification to analyze metabolite abundance, and while reflecting trends, have…

Protein language models are artificial intelligence tools that help us design proteins with useful properties, including entirely new structures never before seen in nature. This technology has great potential to address global challenges, such as synthesizing enzymes that can absorb carbon dioxide from the atmosphere and building catalysts that can significantly reduce energy use and harmful waste byproducts in industrial processes. Even though many of these models are beginning to shape real-world decision-making in biotechnology, major challenges remain. Protein language models (pLMs) operate primarily as black boxes, making it difficult to understand their decision-making processes and determine whether their predictions…

Neurons and white blood cells differ greatly in shape, function, and location in the body. However, researchers at the University of São Paulo (USP) in Brazil found that certain genes were similarly dysregulated in both cell types in patients with depression. The findings not only confirm the systemic nature of depression, which has implications beyond mental health, but also pave the way for future blood tests that can identify the type and severity of depression. The study was published in the journal scientific report. This research was supported by FAPESP through four projects (18/18886-9, 24/21635-9, 23/07806-2, and 23/06086-6). We…
