People sometimes ask, “Is the universe a black hole?” Or worse, they claim: “The universe is a black hole!” No, it’s not, and it’s worth getting this one straight.
If there’s any quantitative reasoning behind the question (or claim), it comes from comparing the amount of matter within the observable universe to the radius [...]

The G-Zero experiment that measures the amount of strange quark contributions to the proton has found that there is a lot less strangeness than previous theories and experiments indicated.

When most people think of March Madness, they think of precision and brawn. But they ought to throw brains into that list. An analysis of the NCAA basketball championship shows that universities that participate in the QuarkNet particle physics outreach program outperform the others in the basketball.

We’re constantly being peppered by showers of debris from cosmic rays colliding with atoms in the atmosphere. Cosmic rays aren’t actually rays, of course, they’re particles; ninety percent are protons, the nuclei of hydrogen atoms, and most of the rest are heavier nuclei like iron. Some originate from our own sun but most come from farther off, from the Milky Way or beyond.

Italy's National Institute of Nuclear Physics, at its laboratories in Gran Sasso, has received 120 lead bricks from an ancient Roman ship that sunk off of the coast of Sardinia 2,000 years ago. The ship's cargo was recovered 20 years ago, thanks to the contribution of the INFN, which at the time received 150 of these bricks. The INFN is now receiving additional bricks to complete the shield for the CUORE experiment, which is being conducted to study extremely rare events involving neutrinos. After 2,000 years under the sea, this lead will now be used to perform a task 1,400 metres under the Apennine mountain.

Two new and independent studies have put Einstein's General Theory of Relativity to the test like never before. These results show Einstein's theory is still the best game in town.

A lightning researcher has discovered that during thunderstorms, giant natural particle accelerators can form 40 km above the surface of the Earth. His findings show that when particularly intense lightning discharges in thunderstorms coincide with high-energy particles coming in from space (cosmic rays), nature provides the right conditions to form a giant particle accelerator above the thunderclouds.

National Accelerator Laboratory Pushing Forward on Alternatives (Vancouver, BC) -- TRIUMF, Canada's national laboratory for particle and nuclear physics, welcomed this morningâs Government of Canada Response to the Report of the Expert Review Panel on Medical-Isotope Production (the Government's Response). The Government's Response identifies a clear strategy for developing accelerator-based technologies for medical-isotope production and bringing them to market. TRIUMF has global expertise in the two proposed thrust areas, cyclotrons and linear accelerators, and looks forward to contributing its time, talent, and leadership to seeing these efforts bear fruit and make a real difference for Canadians.

Geneva 30 March 2010. Beams collided at 7 TeV in the LHC at 13:06 CEST, marking the start of the LHC research programme. Particle physicists around the world are looking forward to a potentially rich harvest of new physics as the LHC begins its first long run at an energy three and a half times higher than previously achieved at a particle accelerator.

Geneva, 23 March 2010. With beams routinely circulating in the Large Hadron Collider at 3.5 TeV, the highest energy yet achieved in a particle accelerator, CERN has set the date for the start of the LHC research programme. The first attempt for collisions at 7 TeV (3.5 TeV per beam) is scheduled for 30 March.

Jacques Martino has been appointed director of CNRSâs National Institute of Nuclear and Particle Physics (IN2P3) by CNRS president Alain Fuchs. Dr. Martino had been director of the Subatech laboratory (CNRS/Ecole des Mines de Nantes/Université de Nantes) since 2001, and director of the Arronax cyclotron public interest group in Nantes. He will take up his new post on April 1st, 2010, replacing Michel Spiro who was elected president of the CERN council last December.

The Borexino Collaboration announced the observation of geo-neutrinos at the underground Gran Sasso National Laboratory of Italian Institute for Nuclear Physics (INFN), Italy. The data reveal, for the first time, a definite anti-neutrino signal with the expected energy spectrum due to radioactive decays of U and Th in the Earth well above background.

Geneva, 19 March 2010. At just after 5:20 this morning, two 3.5 TeV proton beams successfully circulated in the Large Hadron Collider for the first time. This is the highest energy yet achieved in a particle accelerator, and an important step on the way to the start of the LHC research programme. The first attempt to collide beams at 7 TeV (3.5 TeV per beam) will follow on a date to be announced in the near future.

Geneva, 4 March 2010. On Monday 8 March, CERN1 will take on a distinctly feminine look as the laboratory celebrates the role of women in physics. Often seen as a male preserve, the reality is rather different, with women playing key roles across all areas of CERN activity.

Scientists report discovery of heaviest known antinucleus and first antinucleus containing an anti-strange quark, laying the first stake in a new frontier of physics UPTON, NY - An international team of scientists studying high-energy collisions of gold ions at the Relativistic Heavy Ion Collider (RHIC -- http://www.bnl.gov/rhic/), a 2.4-mile-circumference particle accelerator located at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, has published evidence of the most massive antinucleus discovered to date. The new antinucleus, discovered at RHIC's STAR detector (http://www.bnl.gov/rhic/STAR.asp), is a negatively charged state of antimatter containing an antiproton, an antineutron, and an anti-Lambda particle. It is also the first antinucleus containing an anti-strange quark. The results will be published online by Science Express on March 4, 2010.
