Astronomers have for the first time weighed an Earth-sized planet orbiting another star. Although measuring the radius of exoplanets is relatively straightforward, measuring the planet's mass - and therefore its density, a clue to its composition - is more difficult. The results from two independent teams published in Nature (30 October 2013), one of which a number of UK astronomers, confirm Kepler-78b as the first known Earth-sized exoplanet with an Earth-like density...

91福利 physicists could be a step closer to solving the mystery of missing antimatter. They have observed muon neutrino to electron neutrino transformation – a process which could provide a clue to why the Universe has more matter than antimatter...

In 2012, the EPS commissioned an independent economic analysis from the Centre for Economics and Business Research (Cebr) on the importance of physics to the economies of Europe. The report, using statistics available in the public domain through Eurostat, covers 29 European countries – the EU27 countries, plus Norway and Switzerland. Under examination is the 4-year period 2007-2010, 2010 being the most recent year for which official data are simultaneously available for all these countries.
