'Big Bang' particle collider restarts after refit: CERN
 | ZURICH/GENEVA (Reuters) - Scientists at Europe's nuclear research center CERN said on Sunday they had restarted their Large Hadron Collider (LHC) "Big Bang" machine after a two-year refit, launching a new bid to resolve some of the mysteries of the universe. In a live blog covering the restart, CERN said one of the two beams had completed the circuit of the LHC. The LHC had been shut down for two years for a refit of its machinery and wiring. Any new discoveries it makes are unlikely to emerge until mid-2016. (Reporting by Joshua Franklin and Robert Evans; editing by John Stonestreet)

 | ZURICH/GENEVA (Reuters) - Scientists at Europe's particle physics research centre CERN on Sunday restarted their "Big Bang" Large Hadron Collider (LHC), embarking on a new bid to resolve some mysteries of the universe and look for "dark matter". Hopes for the second run lie in breaking out of what is known as the Standard Model of how the universe works at the level of elementary particles, and into "New Physics".

Some people will celebrate Easter this Sunday. Some scientists, meanwhile, will celebrate the birthday of the humble bacterium Helicobacter pylori. H. pylori infects more than half of the world's population. Many people who carry the bacterium won't ever experience any symptoms of the infection, but it's the culprit behind most ulcers and many cases of stomach cancer — and it hid, unidentified, inside human stomachs for thousands of years.
