Probing for principles underlying flock patterns For the casual observer it is fascinating to watch the orderly and seemingly choreographed motion of hundreds or even thousands of fish, birds or insects. However, the formation and the manifold motion patterns of such flocks raise numerous questions fundamental to the understanding of complex systems. A team of physicists from Technische Universitaet Muenchen (TUM) and LMU Muenchen has developed a versatile biophysical model system that opens...

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have obtained the closest look yet of how a gargantuan molecular machine breaks down unwanted proteins in cells, a critical housekeeping chore that helps prevent diseases such as cancer. They pieced together the molecular-scale changes the machine undergoes as it springs into action, ready to snip apart a protein. Their work provides valuable clues as to how the molecular machine, a giant enzyme called...

New method can facilitate customized molecular medicine Apoptosis, programmed cell death, is essential to normal development, healthy immune system function, and cancer prevention. The process dramatically transforms cellular structures but the limitations of conventional microscopy methods have kept much about this structural reorganization a mystery. Now, in research featured on the cover of the current issue of Proceedings of the National Academy of Sciences, University at Buffalo...

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...

barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
