Synopsis
|
Published February 23, 2009 Two antimatter measurements performed by the PAMELA experiment appear to lead to conflicting results. Now, theorists are exploring the extent to which these measurements can be reconciled. |

Synopsis
|
Published January 12, 2009 Branes are multidimensional objects that arise in the formulation of string theory. Finding more general ways to describe these objects mathematically often leads to new insights into string theory itself. |
