The 2014 Fred Beamish Award was awarded to Professor Juewen Liu (Department of Chemistry, University of Waterloo). The Award Lecture titled "Lanthanide-dependent RNA-cleaving DNAzymes as metal biosensors" is published today in the Canadian Journal of Chemistry.
As nanomachine design rapidly advances, researchers are moving from wondering if the nanomachine works to how long it will work. This is an especially important question as there are so many potential applications, for instance, for medical uses, including drug delivery, early diagnosis, disease monitoring, instrumentation, and surgery.
Three of the four most fatal cancers are caused by a protein known as Ras; either because it mutates or simply because it ends up in the wrong place at the wrong time. Ras has proven an elusive target for scientist trying to cure the deadly diseases. Now a group from the Department of Chemistry, University of Copenhagen have discovered an unknown way for RAS to find its proper place in the cell. Their discovery may lead to completely novel approaches to curing cancer.
A major hurdle in structural biology and pharmacology is growing crystals to determine the structure of the biomolecules and pharmaceuticals under study. Researchers at the University of Tübingen, working with colleagues from Oxford and Grenoble, have now observed a key step in the nucleation and growth of some protein crystals.
Nanomedicine has been developing rapidly in recent years, particularly in the development of novel nano tools for medical diagnosis and treatment. For instance, a new trend is becoming prevalent in developing nanosystems for simultaneous tumor diagnosis and therapy.
The use of colloidal silver to treat illnesses has become more popular in recent years, but its ingestion, prohibited in countries like the US, can be harmful to health. Scientists from the Max Planck Institute in Germany have now confirmed that silver nanoparticles are significantly toxic when they penetrate cells, although the number of toxic radicals they generate can vary by coating them with carbohydrates.
Living systems have the ability to produce collective molecular motions that have an effect at the macroscale, such as a muscle that contracts via the concerted action of protein motors.
Applied DNA Sciences, Inc., a provider of DNA-based product authentication solutions, supply chain security and anti-counterfeiting technology, announced today that the Defense Logistics Agency (DLA) DNA marking lab in Columbus, Ohio has now been open for over a month. On-site and on-time, the lab was fully operational on December 15, 2014 with microcircuits beginning to work their way through the administrative system and get to the Product Test Center (PTC).
A new 'microcapsule' treatment delivery method developed by researchers at Queen Mary University of London (QMUL) could reduce inflammation in cartilage affected by osteoarthritis and reverse damage to tissue. The research was funded by Arthritis Research UK and the AO Foundation.
DNA Electronics Ltd (‘DNAe’), the inventors of semiconductor DNA sequencing technology and developers of a new, revolutionary point-of-need test for blood infections, has on 15 January 2015 completed the acquisition of the entire issued share capital of nanoMR Inc. (‘nanoMR’), an Albuquerque based developer of a novel system for rapid isolation of rare cells in the bloodstream for a total cash consideration of approximately $24 million by way of a merger under the laws of Delaware, USA.
