University of Miami researchers are creating fluorescent molecules that can be turned on and off in aqueous environments to visualize activity within cells University of Miami scientists have developed a way to switch fluorescent molecules on and off within aqueous environments, by strategically trapping the molecules inside water-soluble particles and controlling them with ultraviolet light. The new system can be used to develop better fluorescent probes for biomedical research....

A team from the Institute of Photonic Sciences (ICFO) has developed a technique to measure internal cell temperatures without altering their metabolism. This finding could be useful when distinguishing healthy cells from cancerous ones, as well as learning more about cellular processes. Temperature controls many of the cell's life processes, such as splitting and metabolism. A European research team led by the Institute of Photonic Sciences (ICFO), which has the Severo Ochoa mark of...

Efforts are underway to develop a more environmentally friendly process for dyeing denim with indigo, the storied "king of dyes," used to the tune of 50,000 tons annually to color cotton blue jeans and hundreds of other products. That effort is the topic of an article in the current edition of Chemical & Engineering News (C&EN). C&EN is the weekly newsmagazine of the American Chemical Society (ACS), the world's largest scientific society. In the article, C&EN Assistant...

Researchers Increase Speed Of Single-molecule Measurements

New integrated circuit design could lead to cheaper, faster DNA sequencing As nanotechnology becomes ever more ubiquitous, researchers are using it to make medical diagnostics smaller, faster, and cheaper, in order to better diagnose diseases, learn more about inherited traits, and more. But as sensors get smaller, measuring them becomes more difficult–there is always a tradeoff between how long any measurement takes to make and how precise it is. And when a signal is very weak, 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...

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...
