 | All biological sensory systems, including the five human senses, have something in common: when exposed to a sustained change in sensory input, the sense eventually acclimates and notices subsequent changes without comparing them with the initial condition. This autonomous tuning of perceptions, known as sensory adaptation, has been recognized for more than a century. A new study demonstrates that even microbes have sensory adaptation so precise that their behavior remains identical in ever-changing background conditions. ...> Full Article |
A team led by Dr. Doris Heinrich of the Faculty of Physics and the Center for NanoScience at Ludwig-Maximilians-Universität in Munich has developed a novel experimental set-up that allows for the investigation of molecular pathways mediating directed migration of living cells. This method also offers a new way of testing the influence of medical drugs on cell migration strategies.

Using ever-growing genome data, scientists with the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee are tracing the evolution of the bacterial regulatory system that controls cellular motility, potentially giving researchers a method for predicting important cellular functions that will impact both medical and biotechnology research.

 | A group of scientists seeking the answer to the mystery of collective motion has found strong evidence pointing to the idea that collective behavior can arise in cells that initially may not be moving at all, but are prodded into action by an external agent such as a chemical. ...> Full Article |
It's not easy being a bacterium and constantly having to adapt to whatever your environment throws at you. Dr. Robert Endres explains how bacteria rely on their "memories" to fine-tune their ability to sense food and danger, in his talk at the Society for General Microbiology's spring meeting in Edinburgh today.
