  • Young at wrong end of deprivation gap, finds study
    on March 20, 2018 at 1:57 am

    The under-thirties have endured most the marked increase in relative deprivation of any age group in England, according to a 11-year study of data from the Office of National Statistics (ONS). Data scientists reviewed the analysis from 2004-2015 and also found that over the same period, deprivation fell for the over-60s, who are also less likely to live in deprived neighborhoods. […]

  • Scenario 2050: Lithium and cobalt might not suffice
    on March 14, 2018 at 3:08 pm

    Lithium and cobalt are fundamental components of present lithium-ion batteries. New analysis shows that the availability of both elements could become seriously critical. Cobalt-free battery technologies, including post-lithium technologies based on non-critical elements such as sodium, but also magnesium, zinc, calcium and aluminium, represent possibilities to avoid this criticality in the long term.

  • Geopolitical risks to US oil supply lowest since the early 1970s
    on January 5, 2018 at 6:52 pm

    The geopolitical risks to the United States' oil supply are the lowest since the early 1970s, due to fracking, climate action and a more diverse global supply, according to a new paper. America's energy prosperity contrasts with a more fraught period for energy-exporting countries where geopolitical challenges have been compounded by fiscal stress and rising domestic energy demand, the authors said. […]
