Study Shows Genetically Identical Bacteria Can Behave In Entirely Different Ways
2014-01-02 15:32:39

University of Washington Uneven distribution of certain mechanisms during cell division creates diversity that can enhance a bacterial population's survival Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways. This phenomenon is crucial in the bacteria's struggle for survival. The more diversity a population of bacteria has, the more likely it will contain individuals able to take advantage of...

Motorized Microscopic Matchsticks Move In Water With Sense Of Direction
2013-09-10 12:11:39

University of Warwick Chemists, physicists and computer scientists at the University of Warwick have come together to devise a new powerful and very versatile way of controlling the speed and direction of motion of microscopic structures in water using what they have dubbed chemically ‘motorized microscopic matchsticks’. Before now most research seeking to influence the direction of motion of microscopic components have had to use outside influences such as a magnetic field or the...

Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers–early warning beacons announcing the pre-symptomatic presence of cancers and other diseases. While study of the binding properties of membrane proteins is essential, detailed analysis of...

SAN DIEGO, Aug. 4, 2011 /PRNewswire/ -- Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD) announced today the publication of research that uncovered a previously unknown role for a class of molecules that could lead to future advances in immunologic medicine. The findings show a definitive link between EBI2, a G-protein-coupled receptor that controls B-cell migration, and some unexpected immunological effects of certain oxysterols. Co-authored by the...

How cells change direction Many cell types in higher organisms are capable of implementing directed motion in response to the presence of certain chemical attractants in their vicinity. A team led by Dr. Doris Heinrich of the Faculty of Physics and the Center for NanoScience (CeNS) at Ludwig-Maximilians-Universität (LMU) Mnchen has developed a novel technique to expose an ensemble of living cells to rapidly varying concentrations of chemoattractants. "Using this novel experimental...

(Ivanhoe Newswire) "“ A protein identified at the University of Central Florida lab has the power to suppress inflammation, a discovery that could help get to the root causes of disorders like arthritis and heart diseases. A research team led by Pappachan Kolattukudy, director of the Burnett School of Biomedical Sciences, initially discovered MCPIP (Monocyte Chemotactic Protein-1 Induced Protein), which has now been shown to act as a suppressor of inflammation. It does this by...

Call them oil droplets with a brain or even "chemo-rats." Scientists in Illinois have developed a way to make simple oil droplets "smart" enough to navigate through a complex maze almost like a trained lab rat. The finding could have a wide range of practical implications, including helping cancer drugs to reach their target and controlling the movement of futuristic nano-machines, the scientists say. Their study is in the weekly Journal of the American Chemical Society. Bartosz Grzybowski...

A team led by Yale University scientists has developed a new approach to studying how immune cells chase down bacteria in our bodies. Their findings are described in the November 15 issue of Nature Methods Advanced Online Publication. When bacteria enter our bodies they secrete molecules, leaving behind chemical trails as they move through our system. It has been known for some time that immune cells follow these trails in order to hunt the bacteria. However, studying exactly how immune cells...
