In this episode of Physics World Weekly, we look first at the results from Fermilab, which provide evidence for a new type of particle known as a sterile neutrino. Researchers at the Mini Booster Neutrino Experiment (MiniBooNE) say their findings offer a tantalizing glimpse of physics beyond the Standard Model of particle physics. But not everybody agrees.
Later in the programme, Liz Kalaugher speaks about international agreements on curbing fossil fuel emissions and the likelihood of meeting them. She explains why there has been a recent flurry of research papers on the impacts of 1.5 °C warming compared with 2 °C.
Finally, James Dacey explains the concept of “smart cities” – what it means and why we need them. He discusses a recent interview he had with sustainability researcher Bauke de Vries of TU Eindhoven in the Netherlands. De Vries is involved in the Brainport Smart District, a smart city test site being developed near the Dutch city of Helmond.
