August 21, 2013 It's time to reconsider the grand quest for "unification" in modern physics, says commentator Marcelo Gleiser. Our unrelenting search for symmetry and perfection in the natural world leaves us blind to data that seems to depict an imperfect and asymmetric Universe.
February 27, 2013 Scientists have found a Higgs-like particle, a key component in modern physics theory. But is it the Higgs particle, or a new one, part of a more complex model?
January 30, 2013 In the wake of the Hubble Space Telescope and the discovery of the Higgs boson, should we continue to pursue big science projects, in spite of their costs? Commentator Marcelo Gleiser says it's a no brainer.
December 5, 2012 Can scientists create universes in the lab? Although that may not be possible, physicists can recreate the young universe in high energy particle collisions. Recent results indicate that the young universe may be stranger than anticipated.
November 21, 2012 Theories are the life-blood of science; but ruling them out may be harder than you think. And letting a cherished model fall on the trash heap of history is even harder, yet. Take "supersymmetry" from the world of particle physics, for example. When might we see its demise or its vindication?
July 4, 2012 Count your money or look to the stars, either way, the discovery of the Higgs is significant and a significant step forward for humanity.
July 4, 2012 The Higgs, credited with giving particles mass, was the missing piece of the Standard Model of physics. Without it, the world would be a massless mess of photons flying at light speed.
July 2, 2012 Scientists at the Tevatron may be announcing their own results on the Higgs search today.
May 9, 2012 In a time of budget woes, how much should a country invest in basic science research? Commentator Marcelo Gleiser says a country that stops investing in basic research compromises its future.
December 13, 2011 The Higgs might be found. The Higgs might not be found. After all that time and all that effort, the Higgs might not exist in the energies we can probe or, might not exist at all. More data, more observation will eventually give us the answer.
June 7, 2011 The strange existence of anti-matter and its radical imbalance as a cosmic constituent is a fundamental mystery that has persisted for eight decades. We may finally be poised to understand not only the universe that is but also the universe that might have been.
