An international team of researchers, led by scientists at Boston University’s Department of Earth and Environment, has found evidence that material contained in young oceanic lava flows originated at the Earth’s surface in the Archean (>2.45 billions years ago). The new finding helps constrain the timing of the initiation of plate tectonics, the origin of some of the chemical heterogeneity in the Earth’s mantle, and may shed light on how the chaotically convecting mantle could preserve such material for so long. The study appears in the April 25 issue of the journal Nature
A team of researchers led by Artem R. Oganov, a professor of theoretical crystallography in the Department of Geosciences, has made a startling prediction that challenges existing chemical models and current understanding of planetary interiors — magnesium oxide, a major material in the formation of planets, can exist in several different compositions. The team’s findings, “Novel stable compounds in the Mg-O system under high pressure,” are published in the online edition of Physical Chemistry Chemical Physics. The existence of these compounds — which are radically different from traditionally known or expected materials — could have important implications.

Geneva, 25 March 2013. In today's Physical Review Letters, the Antihydrogen TRAP (ATRAP1) experiment at CERN2's Antiproton Decelerator (AD) reports a new measurement of the antiprotonmagnetic moment made with an unprecedented uncertainty of 4.4 parts per million (ppm). This result is 680 times more precise than previous measurements. The unusual increase in precision is due to the experiment’s ability to trap individual protons and antiprotons, and to using a huge magnetic gradient to gain sensitivity to the tiny magnetic moment. ATRAP’s new result is partly an attempt to understand the matter-antimatter imbalance of the universe, one of the great mysteries of modern physics.

The new particle discovered at experiments at the Large Hadron Collider last summer is looking more like a Higgs boson than ever before, according to results announced today.
At the Moriond Conference today, the ATLAS and CMS collaborations at CERN1’s Large Hadron Collider (LHC) presented preliminary new results that further elucidate the particle discovered last year. Having analysed two and a half times more data than was available for the discovery announcement in July, they find that the new particle is looking more and more like a Higgs boson, the particle linked to the mechanism that gives mass to elementary particles. It remains an open question, however, whether this is the Higgs boson of the Standard Model of particle physics, or possibly the lightest of several bosons predicted in some theories that go beyond the Standard Model. Finding the answer to this question will take time.
