Renaissance School Students Win UVA Synthetic Biology Prizes

Posted: Published on October 9th, 2014

Renaissance School Students Win UVA Synthetic Biology Prizes Posted: Thursday, October 9, 2014 1:14 PM EDT Updated: Thursday, October 9, 2014 1:14 PM EDT Renaissance School Press Release Charlottesville, VA. October 9, 2014 - Three seniors in Renaissance School's Synthetic Biology class have won first and second prizes and honorable mention in a "What Synthetic Biology Can Do For You" competition at University of Virginia. Members of UVa's iGem (International Genetically Engineered Machine) team presented the grand prize of $400 to Lauren Ewell for her project concept involving using E. coli to produce leptin, a human hormone, to combat obesity. Jessica Prax won second prize of $100 for her proposal to alter E. coli to produce oxytocin to promote labor during childbirth. Alex Manchester was awarded an honorable mention prize of $25 for his project to improve water quality by using altered E. coli as a parasite in crickets. Renaissance School, in association with the University of Virginia, offers an advanced Synthetic Biology course, allowing high school students to be involved with this emerging engineering discipline involving the redesign and construction of biological systems. iGEM is a group of undergraduates competing in an international program to develop ideas for using … Continue reading

Quantifying physical changes in red blood cells as they mature in the bloodstream

Posted: Published on October 9th, 2014

PUBLIC RELEASE DATE: 9-Oct-2014 Contact: Roy Malka Roy_Malka@hms.harvard.edu 857-294-9492 PLOS During their approximately 100-day lifespan in the bloodstream, red blood cells lose membrane surface area, volume, and hemoglobin content. A study publishing this week in PLOS Computational Biology finds that of these three changes, only the observed surface-area loss can be explained by RBCs shedding small hemoglobin-containing vesicles budding off their cells' membrane. Red blood cell concentration, mean volume, and hemoglobin content are routinely measured in the complete blood count, a fundamental clinical test essential to the screening, diagnosis, and management of most diseases. Variation in mean volume and hemoglobin content is associated with many important clinical conditions, but we do not understand the mechanisms controlling these physical characteristics of red blood cells. Vesicle shedding had been thought to be the most important, but researchers Roy Malka and John Higgins from Massachusetts General Hospital/Harvard Medical School, with colleagues from Massachusetts Institute of Technology, show that a dominant role for vesicle shedding would violate empirical geometric and biophysical constraints. An additional unknown process must be primarily responsible. The study shows that this important process must be coupled to changes in red blood cell surface area and quantifies the magnitude of its … Continue reading
