    C elegans worm venting

    The lifespan of a small roundworm that has been used as a key model organism in ageing research is limited by how it self-sacrifices to feed its young, finds a new study led by UCL researchers.

    The authors of the new Nature Communications paper say their findings raise questions about how well insights from the Caenorhabditis elegans (C. elegans) worm can be translated to human ageing advances.

    C. elegans is widely used as a laboratory animal, and has been central to ageing research for 40 years thanks to discoveries of genes that can be supressed to produce up to a tenfold increase in the worm’s lifespan.

    The UCL research team investigated what drives the lifespan of C...

    Researchers use Quantum Computer to Identify Molecular Candidate for Development of more Efficient Solar Cells

    ORNL team members applied three independent strategies to decrease their project’s computational workload, which reduced their time to solution from months to a few weeks. First, in a technique called qubit tapering, they decreased the number of qubits required to express the problem, reducing the size of the problem itself. Second, they took fewer measurements to solve the problem by measuring groups of terms once rather than measuring each individual term from every group (a process called qubit-wise commutativity). Third, instead of implementing each circuit individually, they found a way to run four circuits in parallel, allowing them to use all 20 qubits in the H1-1. Illustration credit: Adam Malin/ORNL.

    Hubble sees Evaporating Planet getting the Hiccups

    July 31, 2023, Categories  Astronomy/Space

    This artist’s illustration shows a planet (dark silhouette) passing in front of the red dwarf star AU Microscopii. The planet is so close to the eruptive star a ferocious blast of stellar wind and blistering ultraviolet radiation is heating the planet’s hydrogen atmosphere, causing it to escape into space. Four times Earth’s diameter, the planet is slowly evaporating its atmosphere, which stretches out linearly along its orbital path. This process may eventually leave behind a rocky core. The illustration is based on measurements made by the Hubble Space Telescope.

    Fast data transmissions could be delivered in homes and offices through light-emitting diodes (LED) bulbs, complementing existing communication technologies and networks.

    The future’s new internet technologies are being rapidly refined by academics and LED-based communication links are expected to be extensively used in numerous emerging services and scenarios, including Light-fidelity (Li-Fi), underwater communications, moderate- to high-speed photonic interconnects and various ‘Internet of Things’ (IoT) devices.

    A new study led by the University of Surrey and University of Cambridge has investigated how to release high-speed photonic sources using metal-halide perovskites...
