Arizona State Univeristy scientist N.J. Tao and his colleagues at the Biodesign Institute have hit on a new, versatile method to significantly improve the detection of trace chemicals important in such areas as national security, human health and the environment.
Conventional biological wisdom holds that living cells interact with their environment through an elaborate network of chemical signals. As a result many therapies for the treatment of cancer and other diseases in which cell behavior goes awry focus on drugs that block or disrupt harmful chemical signals. Now, a new road for future therapies may have been opened with scientific evidence for a never seen before way in which cells can also sense and respond to physical forces.
Repair proteins appear to efficiently scan the genome for errors by jumping like fleas between DNA molecules, sliding along the strands, and perhaps pausing at suspicious spots, say researchers at the University of Pittsburgh, the University of Essex and the University of Vermont who tagged the proteins with quantum dots to watch the action unfold.
Today at ACAMP's latest seminar, Alberta's conventional energy industry learned how nanotechnology, micro-systems and micro-fluidics can play a powerful role in enhancing operational performance, reducing costs and promoting efficient extraction of oil and gas resources, while opening new markets for Alberta companies worldwide.
Monash Institute of Pharmaceutical Science (MIPS) researchers, in collaboration with the biotechnology company Starpharma Holdings Ltd have developed a new method to deliver medications that may benefit thousands of patients with particular types of cancer, HIV and lymphatic conditions world-wide.
The Colorado Nanofabrication Laboratory at the University of Colorado at Boulder will host a symposium April 2 and a program of interactive, family-oriented outreach activities April 3 as part of NanoDays"2010, the third annual nationwide festival of educational programs about nanoscale science and engineering.
For the first time, researchers have been able to confine and study an individual protein, one that plays a key role in photosynthesis, without having to pin it down so tightly as to alter its fundamental behavior.
By watching how energy moves across a tiny device akin to a springing diving board, Cornell researchers are a step closer to creating extraordinarily tiny sensors that can instantly recognize harmful substances in air or water.
Riso DTU has now with Danish Gas Technology Center (DGC) as partner received support from the Danish Programme for Energy Technology Development and Demonstration (EUPD) to initialize a center which will eventually support industry with test, development, analysis, approval, certification, consultation, and training in the areas of fuel cell and hydrogen technologies.
The weird world of quantum mechanics describes the strange, often contradictory, behaviour of small inanimate objects such as atoms. Researchers have now started looking for ways to detect quantum properties in more complex and larger entities, possibly even living organisms.
Molekuele, die erst bei Bestrahlung mit Licht ihre biologische Funktion entfalten, koennten an genau definierter Stelle im Organismus 'angeschaltet' werden. Wissenschaftlern vom Leibniz-Institut fuer Molekulare Pharmakologie (FMP) und von der Technischen Universitaet Berlin ist es gelungen, solche lichtsensiblen molekularen Strukturen zu entwickeln.
