Canadian scientists helping to unravel the secret of the universe's existence

VANCOUVER - Science is one step closer to solving one of the most profound mysteries in the cosmos due to what an international team of physicists say is an unprecedented observation about a fundamental particle in the universe. Representatives from a team of 400 scientists from 11 countries, including Canada, revealed Friday that, for the first time, a muon neutrino was seen transformed into an electron neutrino — something never witnessed before.

New tests back concept for particle physics

Tests at the world's biggest collider have provided the most exhaustive confirmation to date of the Standard Model, a four-decade-old conceptual framework for fundamental particles, CERN said on Friday. Physicists at two giant underground laboratories straddling the French-Swiss border have given the most accurate measurement yet of a change in a particle called a Bs. New measurements showed that out of every billion Bs particles, only a handful decay into smaller particles called muon, and they do so in pairs, the European Organisation for Nuclear Research (CERN) said.

Edmonton university opens cyclotron, which will make medical isotopes

EDMONTON - The University of Alberta has opened a new cyclotron facility at its south Edmonton campus. The facility will make a reliable supply of medical isotopes for diagnostic imaging. A shutdown of Atomic Energy of Canada Ltd.'s Chalk River research reactor in 2009 caused a worldwide shortage of the medical isotopes used to detect cancer and heart ailments. Ottawa has said isotope production at the Ontario facility will end in 2016.

CORRECTED: Higgs evidence mounts one year on, so too the suspense

A year since the discovery of a subatomic particle set the science world aflutter, evidence is mounting it may be the elusive Higgs boson even as researchers warn the suspense is far from over. "We have established without a doubt that we have a new particle, and that it is a boson. What remains to be done is confirm that it is a Higgs," said physicist Pauline Gagnon, a member of the team that made the discovery at the European Organisation for Nuclear Research (CERN).

Captive particles and Dr. Who show physicists are human too

By Robert Evans GENEVA (Reuters) - Physicists are deadly serious people, right? Clad in long white coats, they spend their days smashing particles together in the hunt for exotic creatures like quarks and squarks, leptons and sleptons -- and the Higgs Boson. At night their dreams are all about finding them.

Scientists find hint of dark matter from cosmos

A $2 billion cosmic ray detector on the International Space Station has found the footprint of something that could be dark matter, the mysterious substance that is believed to hold the cosmos together but has never been directly observed, scientists say.But the first results from the Alpha Magnetic Spectrometer, known by its acronym AMS, are almost as enigmatic as dark matter itself.

First clues in search for universe's dark matter

A massive instrument circling the globe aboard the International Space Station has provided a first glimpse of what may be mysterious dark matter in the universe, experts said Wednesday. The elusive nature of dark matter -- which surrounds the galaxy in a near-spherical halo and is believed to make up around a quarter of the universe -- is considered one of the most important riddles in physics. Dark matter has only been observed indirectly through its interaction with visible matter, and is not explained by the standard model of physics.

First results announced in search for universe's dark matter

A massive science instrument that is spinning the globe aboard the International Space Station has provided its first glimpse of what may be mysterious dark matter in the universe, experts said Wednesday. The first results from the Alpha Magnetic Spectrometer, the most sensitive particle physics spectrometer ever sent to space, seem to indicate "evidence of a new physics phenomena," said a press statement from the international research team.

New data 'strongly indicates' particle is Higgs boson

New data unveiled on Thursday strengthens the belief that a subatomic particle discovered last year is the elusive Higgs boson, European physicists said. Analysis of two characteristics, teased from experiments at the world's biggest particle smasher, aligns with theories that the discovery is a Higgs, the European Organisation for Nuclear Research (CERN) said.
