This week, NSF-funded research was on display on Capitol Hill for “The Arc of Science: Research to Results” event. Scientists whose work provides insights, products, or services to American citizens, businesses, and government interacted with congresspeople, congressional staffers, and representatives from various sectors of the economy, including health care, education, and industry. Guests enjoyed hands-on demonstrations of technologies directly stemming from NSF-funded research.
Attendees learned about BIO-funded research at the exhibit, “QSTORM: Achieving Pinpoint Surveillance Capacity Inside Living Cells.” The Principal Investigator, Dr. Jessica Winter (Ohio State University) and colleagues from the Museum of Science Boston showed how NSF is supporting teams of scientists and engineers to come together to tackle one of the last frontiers of microscopy – obtaining detailed images of the inner workings of living cells. The researchers explained to attendees how new breakthroughs in nanotechnology, chemical engineering, optics, and computer programming are allowing them to address this challenge.
Visitors to the exhibit had the opportunity to “turn on” a real set of amazingly bright and colorful quantum dots–the researchers use these to illuminate the tiniest features inside cells. Then, using a styrofoam and slinky model, the team demonstrated how they “turn off” a quantum dot using a gold nanoparticle tethered by a strand of DNA. Attendees learned how STORM super-resolution microscopy can reconstruct detailed images from overlays of pinpoint dots of light.

The QSTORM project, originally funded in 2010, has since received a second grant from NSF to work on implementing new imaging techniques made possible by the original science and to help establish partnerships which otherwise may not have come to be. Dr. Winter is working with the Museum of Science Boston to develop several hands-on demonstrations to explain the science of quantum dots to a broader audience.
The Arc of Science event was coordinated by the National Science Foundation and the Coalition for National Science Funding. Invited speakers included NSF Director Dr. France A. Córdova, Congressman Lamar Smith (R-TX), Congresswoman Eddie Bernice Johnson (D-TX), and Senator Gary Peters (D-MI).
