Brain Tumour Foundation of Canada is assisting Canadian research nationally in the mission to find a cause of and cure for brain tumours with the announcement of its annual grants-in-aid program recipients.
A team at the University of Nebraska-Lincoln has figured out a possible way to observe and record the behavior of matter at the molecular level. That ability could open the door to a wide range of applications in ultrafast electron microscopy used in a large array of scientific, medical and technological fields.
How can you weigh a single atom? European researchers have built an exquisite new device that can do just that. It may ultimately allow scientists to study the progress of chemical reactions, molecule by molecule.
Using a sophisticated mathematical model that relates a wide variety of biological variables to disease progression, a research team has shown that accounting for the shape and physical characteristics of the tumor margin and invasiveness of the tumor accurately predicts how a particular tumor will develop and metastasize.
Quantum dots (QDs), nanoparticles that shine with extraordinary brightness when excited by light energy, have shown promise as new tools for detecting cancer at its earliest appearance, but concerns about potential toxicities have limited their clinical development. Researchers at the University of Buffalo may have found an answer to this limitation with their development of a new way to create QDs. Their work comes at an opportune time, because a team of investigators from the University of Texas at Arlington (UTA) has shown that QDs can function as nanoscale thermometers to guide the numerous nanoparticle-based thermal therapies being developed to treat cancer.
A research team at Northwestern University has developed a tool that can precisely deliver tiny doses of drug-carrying nanomaterials to individual cells. The tool, called the nanofountain probe, functions in two different ways. In one mode, the probe acts like a fountain pen with drug-coated nanodiamonds serving as the ink, allowing researchers to create devices by 'writing' with it. The second mode functions as a single-cell syringe, permitting direct injection of biomolecules or chemicals into individual cells.
Carbon nanotubes, one of the original engineered nanomaterials, also may prove to be among the most versatile, as numerous teams of investigators continue to develop novel nanotube-based therapeutic and diagnostic tools. Over the past month, three new research papers have highlighted the potential of nanotubes as weapons against cancer.
By taking two standard laboratory techniques - capillary electrophoresis and antibody-based protein detection - and shrinking them to the nanoscale, researchers at the Stanford University School of Medicine have created a new method for detecting miniscule changes in the levels of proteins associated with cancer.
