A team of researchers at Washington University in St. Louis, headed by Srikanth Singamaneni, PhD, assistant professor of mechanical engineering & materials science, unexpectedly found the mechanism by which tiny single molecules spontaneously grow into centimeter-long microtubes by leaving a dish for a different experiment in the refrigerator.
University of California, San Diego bioengineers have demonstrated in a study in pigs that a new injectable hydrogel can repair damage from heart attacks, help the heart grow new tissue and blood vessels, and get the heart moving closer to how a healthy heart should. The results of the study were published Feb. 20 in Science Translational Medicine and clear the way for clinical trials to begin this year in Europe. The gel is injected through a catheter without requiring surgery or general anesthesia -- a less invasive procedure for patients.
A Texas A&M University chemist has been awarded a prestigious award meant to kick-start the careers of promising junior faculty members.
3M Food Safety today announced its 3M™ Molecular Detection Assay Salmonella has received an extension of the current NF VALIDATION certificate from AFNOR CERTIFICATION. The Paris-based AFNOR CERTIFICATION expert committee found 3M’s assay to be as or more effective than standard methods for detecting Salmonella spp. in seafood and vegetable products as well as in environmental samples taken from food processing sites.
XEI Scientific Inc, maker of the popular EVACTRON® De-Contaminator™ Plasma Cleaning System for electron microscopes and other vacuum chambers, reports on the recent announcement that the company has been awarded a patent for its innovative TEM Wand™ technology.
Thanks to its high output power, the digital single-channel controller E-709.CHG from PI (Physik Instrumente) provides highly dynamic and nanometer-precise operation of piezo-based stages with high stiffness and electrical capacitance.
Until now, however, it was practically impossible to accurately predict which molecules performed well on the job. They basically had to be identified by trial-and-error.
The UK's national synchrotron facility, Diamond Light Source, is now the first and only place in Europe where pathogens requiring Containment Level 3 – including serious viruses such as those responsible for AIDS, Hepatitis and some types of flu – can be analysed at atomic and molecular level using synchrotron light. This special light allows scientists to study virus structures at intense levels of detail and this new facility extends that capability to many viruses that have a major global impact on human and animal health. Studying pathogens in this way has the potential to open up new paths for the development of therapeutic treatments and vaccines.
When difficult biological questions are tackled by creative experts in physics, what can result? Images of great beauty, accessible for anyone to appreciate, that also offer rich information on fundamental life processes, and rewarding new paths for analysis and insight.
In perhaps no other scientific field does the adage "form follows function" hold more true than in biology, especially the biology of living cells, which is why our knowledge of cells starts with imaging. Optical microscopy is limited by low spatial resolution – about 200 nanometers, and electron microscopy is limited by the poor penetration of electrons and the requirement that it be performed in a vacuum, which means cells must be sectioned off into tissue-thin slices and dehydrated. X-ray microscopy bridges the resolution gap between optic and electron microscopy, combining the best features of both to hit the sweet spot for chemical and elemental imaging.
