Studies on common bakers yeast have led to the discovery of what may be a long-sought mechanism in the life cycle of retroviruses, including the human immunodeficiency virus (HIV). Knowing the details of this step in the infection process could help pinpoint targets for new classes of drugs to fight HIV.
In the Jan. 9 issue of the journal Science, Thomas Menees and Zhi Cheng of the University of Missouri-Kansas City describe the formation of a lariat structure with the genetic material of retrovirus-like elements in bakers yeast and subsequent cutting of the lariat by a yeast enzyme. The findings reported in Science and in the December 2003 Journal of Virology are the payoff of a three-year research gamble by Menees and two postdoctoral researchers pursuing host-cell factors in retroviral infections.
In addition to filling a gap in biologists understanding of how retroviruses replicate, it may turn out that similar lariat structures occur elsewhere in healthy cells and play previously unrecognized roles in cellular processes such as gene activation.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
