CAMBRIDGE, Mass., Oct. 16, 2012 /PRNewswire/ -- Energid Technologies Corporation has been chosen to apply its Actin(TM) software to robotic systems being developed by AREVA Corporation for servicing and inspection of nuclear power plants. As robotics technology continues to advance, potentially dangerous manual servicing and inspection missions are being replaced by robotics. AREVA is at the forefront of this trend, seeking safe, effective, robotic solutions to myriad problems encountered...

PHILADELPHIA, July 24, 2012 /PRNewswire/ -- Robai has released the most advanced version of its Cyton(TM) robot arms, the Cyton Gamma(TM). The Cyton Gamma is different from typical industrial robot arms in that it is modeled after the human arm -- the shoulder and wrist each have three axes and the elbow has one. These seven axes make the arm what researchers call kinematically redundant, meaning there is more than one way to move the axes to achieve a particular hand motion....

Max Planck scientists bring the basis of muscle movement into sharper focus Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. While theoretical models have in fact described exactly how these muscle proteins interact, this interaction has never previously been observed in detail. Stefan Raunser and Elmar Behrmann from the Max Planck...

An actin-ratchet tightens the contractile ring that severs budding daughter cells from their yeast mothers During the final stage of cell division, a short-lived contractile ring constricts the cellular membrane and eventually separates the dividing cell in two. Although this "molecular muscle's" composition, mainly actin and myosin, is similar to its skeletal counterpart, the force-producing mechanism is fundamentally different, report researchers at the Stowers Institute for Medical...

University of Guelph researchers have found the location and effect of abnormal heart proteins that can cause cardiac failure, a discovery that points to potential new ways to treat the most costly health problem in the world. The study appears today in PLoS ONE, a peer-reviewed international journal published by the Public Library of Science. It is available online: http://dx.plos.org/10.1371/journal.pone.0036821 "In order to cure heart disease, you have to understand its fundamental...

Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments. Cells without functional lamellipodia are still highly motile but lose their ability to stay on track, report researchers at the Stowers Institute for Medical Research in the April 9, 2012, online issue of the Journal of Cell Biology. Their study provides new insight into cell motility, a complex and integrated process, which, when...

A new design triples efficiency of cyan fluorescent proteins Scientists have designed a molecule which, in living cells, emits turquoise light three times brighter than possible until recently. This improves the sensitivity of cellular imaging, a technique where biological processes inside a living organism are imaged at high resolution. The results have been published in Nature Communications on 20 March 2012. The lead author of the publication is Antoine Royant from the Institut de...

CAMBRIDGE, Mass., March 2, 2012 /PRNewswire/ -- Energid Technologies Corporation has released version 3.0 of its Actin software toolkit. Actin provides advanced control tools and digital simulation for roboticists. Robots are growing in capability and economic impact. Much of this growth is driven by faster computer algorithms and software. Energid's Actin toolkit embodies this driving force. Actin allows roboticists to design complex robots using Computer Aided Design (CAD) programs,...

Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells. The study proposed a new model to explain how mammalian cells establish the sense of direction necessary to move, as well as the mechanism that a disease-causing form of E. coli bacteria employ to hijack that ability. Cells need to orient...

The proteins actin, myosin and titin are big players in the business of muscle contraction. Scientists at the European Molecular Biology Laboratory (EMBL) in Hamburg, Germany, have now examined another muscle protein — myomesin — which they discovered can stretch up to two-and-a-half times its length, unfolding in a way that was previously unknown. The study is published 14 February in the open-access, online journal PLoS Biology. Myomesin links muscle filaments, which stretch...
