The first-ever identification of a deep-space source of the super-energetic subatomic high-energy neutrino particles has launched a new era of space research. Detection of one such neutrino beneath the Antarctic ice sent a global team of astronomers racing to track down its origins: a flaring supermassive black hole 3.7 billion light years from Earth. A report will be published in the journal Science by the IceCube team and collaborators, including multiple Penn State coauthors.

A new method allows researchers to systematically identify specialized proteins that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions.
