A research team has developed a light beam device that could lead to faster internet, clearer images of space and more detailed medical imaging.
Researchers at the University of Washington unveiled a new strategy to keep proteins intact and functional in synthetic biomaterials for tissue engineering. Their approach modifies proteins at a specific point so that they can be chemically tethered to the scaffold using light. Since the tether can also be cut by laser light, this method can create evolving patterns of signal proteins throughout a biomaterial scaffold to grow tissues made up of different types of cells.
Some patients with atrial fibrillation or A-Fib need an ablation, which requires a catheter and an advanced 3D map of the heart. Researchers have developed the first algorithm that guides catheter movements and accurately detects A-Fib targets without 3D maps of the heart. In human simulations, this technique stops the catheter at the right target and identifies the source type with a 95.25% success rate and a 99 percent detection rate of scar tissue, regardless of scar size.
Researchers have identified how the human brain is able to determine the properties of a particular object using purely statistical information: a result which suggests there is an 'inner pickpocket' in all of us.
Researchers at McMaster University have invented a stable, affordable way to store fragile vaccines for weeks at a time at temperatures up to 40C, opening the way for life-saving anti-viral vaccines to reach remote and impoverished regions of the world.
Endangered penguins respond rapidly to changes in local fish numbers, and monitoring them could inform fisheries management and marine conservation.
Medical University of South Carolina investigators have exploited a metabolic quirk of certain cancers known as glutamine addiction to identify a potential new therapy for esophageal cancer. After characterizing the pathway involved in cancer progression, they tested a new combination treatment in both cells and animal models, with promising results. The next step is to secure funding to bring the new combination regimen to clinical trial. Their findings are reported in Nature Communications.
A team of Lehigh University researchers is working to characterize the mysterious protein known as the Von Willebrand Factor (vWF). In a recent paper published in Biophysical Journal, they advance experimental data for the shear-induced extensional response of vWF, using a microfluidic device and fluorescence microscopy.
The June issue of SLAS Technology features the article, 'Next Generation Compound Delivery to Support Miniaturized Biology,' which focuses on the challenges of changing the established screening paradigm to support the needs of modern drug discovery.
Researchers from Washington State University and Ohio State University have developed a low-cost, easy way to make custom lenses that could help manufacturers avoid the expensive molds required for optical manufacturing.
