Using tiny micromotors to diagnose and treat disease in the human body could soon be a reality.  Scientists at the University of Illinois at Urbana-Champaign have produced the most precise picture to date of population dynamics in fluctuating feast-or-famine conditions.  For planetary protection, this indicates that more stringent cleaning steps may be needed for missions focused on life detection and highlights the potential need to use differing and rotating cleaning reagents that are compatible with the spacecraft to control the biological burden.  Now an international team of researchers has found a new way to investigate how Tb bacteria inactivate an important family of antibiotics: They watched the process in action for the first time using an X-ray free-electron laser, or XFEL.  A protein complex called facilitates chromatin transcription (FACT) plays a role in DNA packing within a nucleus, as well as in oncogenesis.
