    Hubble provides Holistic View of Stars gone Haywire

    1) The “wings” of NGC 6302 are regions of gas heated to more than 36,000 degrees Fahrenheit that are tearing across space at more than 600,000 miles an hour. NGC 6302 lies between 2,500 and 3,800 light-years away in the constellation Scorpius.
    2) Recently, NGC 7027’s central star was identified in a new wavelength of light — near-ultraviolet — for the first time by using Hubble’s unique capabilities

    As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas...

    Our Deepest View of the X-ray Sky

    June 21, 2020, Categories  Astronomy/Space

    The energetic universe: The first eROSITA all-sky survey was conducted over a period of six months by letting the telescope rotate continuously, thus providing a uniform exposure of about 150-200 seconds over most of the sky, with the ecliptic poles being visited more deeply. As eROSITA scans the sky, the energy of the collected photons is measured with an accuracy ranging from 2% – 6%. To generate this image, in which the whole sky is projected onto an ellipse (so-called Aitoff projection) with the centre of the Milky Way in the middle and the body of the Galaxy running horizontally, photons have been colour-coded according to their energy (red for energies 0.3-0.6 keV, green for 0.6-1 keV, blue for 1-2.3 keV).

    Sedentary Behavior Independently predicts Cancer Mortality

    June 20, 2020, Categories  Health/Medical, Biology/Biotechnology

    Replacing sitting time with 30 minutes of activity associated with lower risk of cancer death. In the first study to look at objective measures of sedentary behavior and cancer mortality, researchers from The University of Texas MD Anderson Cancer Center found that greater inactivity was independently associated with a higher risk of dying from cancer. The most sedentary individuals had an 82% higher risk of cancer mortality compared to the least sedentary individuals. An accelerometer was used to measure physical activity, rather than relying on participants to self-report their activity levels

    “This is the first study that definitively shows a strong association between not moving and cancer death,” said Susan Gilchrist, M.D...

    Graphene Smart Textiles developed for Heat Adaptive Clothing

    Graphene Smart Textiles The University of Manchester
    Using electro-optical tunability of graphene, adaptive optical textiles were made with electrically controlled reflectivity and emissivity covering the infrared and near-infrared wavelengths.

    New research on the two-dimensional (2D) material graphene has allowed researchers to create smart adaptive clothing which can lower the body temperature of the wearer in hot climates.

    A team of scientists from The University of Manchester’s National Graphene Institute have created a prototype garment to demonstrate dynamic thermal radiation control within a piece of clothing by utilising the remarkable thermal properties and flexibility of graphene. The development also opens the door to new applications such as, interactive infrared displays and covert infrared communication on textile.
