Individual cells modified to act as sensors using fluorescence are already useful tools in biochemistry, but now they can add good timing to their resumé, thanks in part to expertise from the National Institute of Standards and Technology (NIST). With the added capability to track the timing of dynamic biochemical reactions, cell sensors become more useful for many studies, such as measurements of protein folding or neural activity. As described in the Journal of the...

North Carolina State University researchers have created specially engineered mammalian cells to provide a new "chemical handle" which will enable researchers to label proteins of interest more efficiently, without disrupting the normal function of the proteins themselves or the cells in which they are found. Protein labeling is used by researchers in a variety of fields to help them understand how these important molecules affect the normal functioning of cells. Currently, proteins are...

Rice University researchers show how length, imperfections affect carbon nanotube fluorescence A painstaking study by Rice University has brought a wealth of new information about single-walled carbon nanotubes through analysis of their fluorescence. The current issue of the American Chemical Society journal ACS Nano features an article about work by the Rice lab of chemist Bruce Weisman to understand how the lengths and imperfections of individual nanotubes affect their fluorescence...

Research presented at ASCB annual meeting New fluorescent labeling technology that distinguishes in a single image the population size and spatial distribution of 15 different taxa has uncovered new taxon pairings that indicate unsuspected cooperation -- and standoffishness -- between members of the microbe biofilm that covers teeth, according to a presentation on Dec. 7, at the American Society for Cell Biology's Annual Meeting in Denver. Members of the genera Prevotella and...

A revolutionary approach to illumination It was not too long ago that basic science lectures began with the three forms of matter: gases, liquids and solids–and somewhere along the line plasmas were occasionally added to the list. But to be precise, a plasma is an ionized gas; thus, a subset of the big three. But this subset has coexisted with the other forms since the Big Bang and actually makes up 99 percent of the universe. It is found in our Sun and all the other stars, and in...
