    To build better aircraft, watch the birdie (and the bee)
    “By mimicking birds, which have similar flight constraints as planes, we can look at developing systems that can more easily adapt to different speeds and conditions such as landing, cruise, and take-off,” says Ingo Schiffner, a researcher at the...

    Nano device measures molecule shape
    Having created the first mechanical device that can measure the mass of individual molecules, one at a time, a team of scientists has now devised nanodevices that can also reveal their shape. That type of information is crucial when trying to...

    The famous olive trees of Puglia are ravaged by disease – here’s how we can save them
    In Puglia in southeastern Italy, 241,000 hectares of olive groves have been restricted, with at least 10% of the 11m olive trees in the worst-affected region, Lecce, infected by the Xilella fastidiosa bacterium. Author: Marcello Nicoletti...
  • Wind resource vertical extrapolation for wind energy purposes

    Energy   26 March 2015   Giovanni Gualtieri
    Wind resource vertical extrapolation for wind energy purposes
    Vertical extrapolation of a variable is the estimation of its upper height (unknown) value based on its lower height (known) value. Thus, starting from simple surface measurements, it is a clear advantage to be enabled to infer the wind speed...
  • Gene therapy for spinal muscular atrophy with respiratory distress type1(SMARD1)

    Gene therapy for spinal muscular atrophy with respiratory distress type1(SMARD1)
    Spinal muscular atrophy with respiratory distress type 1 (SMARD1), is a fatal genetic motor neuron disease with infantile onset, likely underestimated as frequency, and without any effective therapy. It is the second most frequent form of spinal...

    A ‘bionic leaf’ turns solar energy into chemicals and fuels
    But despite its awesome power, the photosynthesis process is extremely inefficient. We can’t really blame plants for this because photosynthesis evolved for ancient earth’s conditions. Image - The concept: a solar-powered fuel or chemical...
