Isaac Newton, world's most famous alchemist Discover Magazine Share    
Jan. 4 issue - Lawrence Principe was sorting through a collection of old chemistry books at the Chemical Heritage Foundation in Philadelphia when he stumbled upon a forgotten manuscript handwritten by Sir Isaac Newton. Any Newton manuscript is of interest, but this one was worth its weight in gold, literally. More
A humble heavyweight in physics finally gets his due The Chronicle of Higher Education Share
Feb. 16 issue - A black hole, though massive, is so tough to see that it typically gains notice only through the effects it has on its surroundings in space. Much the same can be said for Ezra T. Newman, this year's studiously unassuming winner of the American Physical Society's biennial Einstein Prize, one of the most prestigious awards in physics. More Religion may become extinct in 9 nations, study says BBC News Share
March 23 issue - A study using census data from nine countries shows that religion there is set for extinction, say researchers. The study found a steady rise in those claiming no religious affiliation. The team's mathematical model attempts to account for the interplay between the number of religious respondents and the social motives behind being one.

Apr. 20 issue - If the usual ideas of how bicycles balance themselves are right, this weird contraption ought to quickly topple over. In fact it stays upright, an observation that might lead to a rethink of bicycle dynamics - and perhaps to better bike designs. More
52 years and $750 million prove Einstein was right BBC News Share
May 11 issue - In a tour de force of technology and just plain stubbornness spanning half a century and costing more than $750 million, a team of experimenters reported that a set of orbiting gyroscopes had detected a slight sag and an even slighter twist in space-time. More Wave function directly measured ScienceNews Share
June 15 issue - The fuzzy quantum shape that describes the speed or location of a single particle, its wave function, has now been directly measured in the laboratory, giving this mathematical concept a small dose of reality. More States ranked best to worst on science education MSNBC Share
July 13 issue - A new ranking of how well the United States' schools are preparing students for science and engineering careers shows that although there's a small number of high performers, most states are doing a poor job of educating students in these subjects. More
Is dark matter an illusion? PhysOrg Share
Aug. 17 issue - One of the biggest unsolved problems in astrophysics is that galaxies and galaxy clusters rotate faster than expected, given the amount of existing baryonic (normal) matter. The fast orbits require a larger central mass than the nearby stars, dust, and other baryonic objects can provide, leading scientists to propose that every galaxy resides in a halo of (as yet undetectable) dark matter made of non-baryonic particles. One physicist has now proposed that dark matter may be an illusion caused by the gravitational polarization of the quantum vacuum.

Sept. 14 issue - A mathematical model may explain how the nerves in your ear sense harmony, a team of biophysicists reports. The model suggests that pleasant harmonies cause neurons to fire in regular patterns whereas discordant notes stimulate messier neuron activity. Read the associated Physical Review Focus article. More 'Tension' emerges within OPERA collaboration PhysicsWorld Share
Oct. 12 issue - The claim by a team of researchers in Italy that neutrinos can travel faster than the speed of light will require extra checks before being submitted to a peer-reviewed journal. That is the position of a number of researchers in the OPERA collaboration, which announced on Sept. 23 that it had observed superluminal neutrinos travelling from the CERN particle-physics lab near Geneva to the Gran Sasso underground lab in central Italy. More Quantum physics to the rescue after the kilogram develops a weight problem Daily Mail Share
Nov. 9 issue - Ever since 1889, the world could rest assured that a kilogram was a kilogram because of a little metal cylinder kept under glass in France. But recently, the cylinder - known as the International Prototype Kilogram (IPK) - was discovered to have been quietly letting itself go - changing its mass by around 50 micrograms. More Astronomers find evidence of a special direction in space Scientific American Share
Dec. 14 issue - The universe has no center and no edge, no special regions tucked in among the galaxies and light. No matter where you look, it's the same - or so physicists thought. This cosmological principle - one of the foundations of the modern understanding of the universe - has come into question recently as astronomers find evidence, subtle but growing, of a special direction in space.
