New strategy boosts speed, accuracy in simulation of protein folding All proteins self-assemble in a fraction of the blink of an eye, but it can take a long time to mimic the process. And there has been no guarantee of success, even with the most powerful computers "“ until now. Rice University researchers have come up with a computer program to accurately simulate protein folding dramatically faster than previous methods. It will allow scientists to peer deeper into the roots of...

New technique can sense movement of single molecules over hours Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique by Rice University researchers will allow them to track single molecules without modifying them -- and it works over longer timescales. In the current issue of Nanotechnology, a team led by Jason Hafner, an associate professor of physics and astronomy and...

A first view of shape-shifting movements in membrane transporters; hailed as a breakthrough in understanding membrane transport, research may lead to better treatments for depression and substance abuse In what has been hailed as a breakthrough, scientists from Columbia University Medical Center and Weill Cornell Medical College have outlined the molecular mechanism of membrane transport. The research shows how a protein transforms its shape to transport substances across the cell membrane in...

Understanding how mixtures of proteins assemble and how to manipulate them in the laboratory has many exciting biomedical applications, such as providing scaffolds for the engineering of tissues that can replace diseased or damaged human tissues. Now, research published by Cell Press in the April 20th issue of Biophysical Journal, reveals new information about the kinetics of protein assembly and demonstrates how to manipulate conditions in order to provide different distributions of protein...

A team of University of Toronto chemists have made a major contribution to the emerging field of quantum biology, observing quantum mechanics at work in photosynthesis in marine algae. "There's been a lot of excitement and speculation that nature may be using quantum mechanical practices," says chemistry professor Greg Scholes, lead author of a new study published this week in Nature. "Our latest experiments show that normally functioning biological systems have the capacity to use quantum...

University of Michigan researchers have shown that tension on DNA molecules can affect gene expression---the process at the heart of biological function that tells a cell what to do. Scientists understand the chemistry involved in gene expression, but they know little about the physics. The U-M group is believed to be the first to actually demonstrate a mechanical effect at work in this process. Their paper is published in the current edition of Physical Review Letters. "We have shown that...

Single-molecule, real-time measurements of a key biological process Biophysicists at TUM, the Technische Universitaet Muenchen, have published the results of single-molecule experiments that bring a higher-resolution tool to the study of protein folding. How proteins arrive at the three-dimensional shapes that determine their essential functions "“ or cause grave diseases when folding goes wrong "“ is considered one of the most important and least understood questions in the...

U of Minnesota researcher leads study Researchers at the University of Minnesota have discovered a molecular security system in human cells that deactivates and degrades foreign DNA. This discovery could open the door to major improvements in genetic engineering and gene therapy technologies. Led by Reuben Harris, associate professor of biochemistry, molecular biology and biophysics in the College of Biological Sciences, the report's findings was published online by Nature Structural and...

Members of a Syracuse University research team have shown that an obscure phenomenon called stochastic resonance (SR) can improve the clarity of signals in systems such as radar, sonar and even radiography, used in medical clinics to detect signs of breast cancer. It does this by adding carefully selected noise to the system. The result has been a distinct improvement in the system's ability to correctly identify precancerous lesions, plus a 36 percent reduction in false positives. The...
