A novel technology that can test cells in minutes for responses to any stimulus, including antibiotics, pathogens, toxins, radiation or chemotherapy, has been developed by scientists at the University at Buffalo.
The paper describing the sensor will appear in the Feb. 15 issue of Analytical Chemistry, and currently is available as an "ASAP" article on the American Chemical Society Web site http://www.chemistry.org.
Susan Z. Hua, Ph.D., UB assistant professor of mechanical and aerospace engineering and physiology and biophysics, is the lead researcher. The technology is based on the universal connection between cell volume and the cell environment, or cell volume cytometry. It is particularly useful because it eliminates the need to culture bacteria to assess their sensitivity to antibiotics. "Now, in a matter of minutes, we can tell if particular antibiotics are active against specific bacteria," said Frederick Sachs, Ph.D., professor of physiology and biophysics at UB, co-director of UB’s Center for Single Molecule Biophysics and a coauthor on the paper. "We have measured the sensitivity to antibiotics of different strains of E. Coli in less than 10 minutes at room temperature. We will get results even faster at higher temperatures."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
