Like other living creatures, bacteria guarantee their future by passing down DNA to their children. E. coli are tremendously gifted at this, typically splitting down the middle into two daughter cells and providing each with a full set of chromosomes.

Haidong Zhou, an assistant professor in physics and astronomy, is not a scientist who is easily daunted by frustration. In
Scientists, including a group of UT faculty and students, on the world’s longest-distance neutrino experiment have announced that they have seen their first neutrinos. Neutrinos are abundant in nature, but they very rarely interact with other matter. Studying them could yield crucial information about the early moments of the universe.
When it comes to neutron stars, there really is more going on beneath the surface than you might suspect. Associate Physics Professor William R. (Raph) Hix and his colleagues have recently found a layer inside the crust of these stars that actually cools them down instead of heating them up, challenging common scientific perceptions.
The Royal Swedish Academy of Sciences has awarded the Nobel Prize in physics to Peter Higgs and Francois Englert for their research on what has come to be called the Higgs field, which gives elementary particles mass. The UT High Energy Physics group has been part of the hunt for the Higgs boson since 2006, working with the Large Hadron Collider at CERN.
Nanowire networks have become very common in electronic devices. But given their scale, they can be tricky to make. Working with physics professor Hanno Weitering, graduate student Saban Hus set out to develop a new way to grow ultrathin wires in which the wires grow with equal distances between them. This can help streamline the process of making integrated circuits.
Witold Nazarewicz, James McConnell Distinguished Professor of Physics, has been selected as a 2013 UT-Battelle Corporate Fellow. The rank of corporate fellow –among Oak Ridge National Laboratory’s highest honors—recognizes the researchers’ significant accomplishments and continuing leadership in their scientific, engineering and technological fields.
Physics Professor Elbio Dagotto has written a review of new iron-based superconductors for the journal Reviews of Modern Physics. In his detailed colloquium citing hundreds of references, Dagotto points out how research into high-temperature superconductors has steadily advanced in a short period of time.
Three professors at UT have received National Science Foundation Faculty Early Career Development (CAREER) awards. David Jenkins, an assistant professor in chemistry; Jaan Mannik, an assistant professor in physics; and Jeff Reinbolt, an assistant professor of mechanical, aerospace, and biomedical engineering, will use the monetary awards to support their research and educational activities.
Jaan Mannik, assistant professor of physics, has received a National Science Foundation Faculty Early Career Development (CAREER) award. The CAREER award is the NSF’s most prestigious honor for junior faculty who demonstrate outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.
