    An analysis of a clinical trial of more than 2,500 people with Type 2 diabetes and kidney disease found that high levels of four biomarkers are strongly predictive for the development of heart and kidney issues.

    A simple blood test may predict the risk of progressive heart and kidney disease in people with Type 2 diabetes and kidney disease, according to new research published today in the American Heart Association’s flagship journal Circulation.

    “High levels of certain biomarkers are indicators of heart and kidney complications and may help predict future risk of disease progression,” said lead author James Januzzi, M.D...

    A new, superior alternative has emerged in the world of sustainable battery systems. Zinc-air batteries have emerged as a better alternative to lithium in a recent Edith Cowan University (ECU) study into the advancement of sustainable battery systems.

    ECU’s Dr Muhammad Rizwan Azhar led the project which discovered lithium-ion batteries, although a popular choice for electric vehicles around the world, face limitations related to cost, finite resources, and safety concerns.

    “Rechargeable zinc-air batteries (ZABs) are becoming more appealing because of their low cost, environmental frie...

    Side-by-side images of the Ring Nebula where the nebula appears as a distorted doughnut. On the right, the nebula’s inner cavity hosts shades of blue and green, while the detailed ring transitions through shades of orange in the inner regions and pink in the outer region. On the left, the nebula’s inner cavity hosts shades of red and orange, while the detailed ring transitions through shades of yellow in the inner regions and blue/purple in the outer region. The ring’s inner region has distinct filament elements.
    New images from NASA’s James Webb Space Telescope of the well-known Ring Nebula provide unprecedented spatial resolution and spectral sensitivity. In the NIRCam (Near-Infrared Camera) image on the left, the intricate details of the filament structure of the inner ring are particularly visible in this dataset. On the right, the MIRI (Mid-InfraRed Instrument) image reveals particular details in the concentric features in the outer regions of the nebulae’s ring.

    Imagine a person on the ground guiding an airborne drone that harnesses its energy from a laser beam, eliminating the need for carrying a bulky onboard battery.

    That is the vision of a group of University of Colorado at Boulder scientists from the Hayward Research Group.

    In a new study, the Department of Chemical and Biological Engineering researchers have developed a novel and resilient photomechanical material that can transform light energy into mechanical work without heat or electricity, offering innovative possibilities for energy-efficient, wireless and remotely controlled systems. Its wide-ranging potential spans across diverse industries, including robotics, aerospace and biomedical devices.

    “We cut out the middle man,...
