Neighborhood Lecture Series
Our Broad Branch Road Spring 2017 Neighborhood Lecture Series kicks off with Carnegie Science President, Dr. Matthew P. Scott. Scott will present, "Jumping Genes: What They Mean for Evolution and Medicine" at 6:30 p.m on Thursday, March 16, 2017, in the Greenewalt Lecture Hall.
The DNA of one human cell—two copies of our “genome”—would stretch almost two meters if fully extended. However, normally it’s tightly packaged in 46 chromosomes. About 20,000 genes are distributed along this DNA; they carry the information for building and operating a human. Any particular gene is located at a specific place in a chromosome and, normally, stays there. Carnegie scientist Barbara McClintock discovered, in corn, that some genes jump from one place in a chromosome to another. Similar things occur in most organisms, including us. This discovery, which earned a Nobel prize, led to dramatic advances in understanding infectious disease, evolution, and the controls that turn genes on and off in specific places and tissues. This talk will discuss early life on Earth, how jumping genes may have influenced it, and why we should care about jumping genes now…for example if you use antibiotics.
Doors open at 6 p.m. Lecture Hall seating is first come, first serve. Eventbrite tickets are not required, so please arrive early to reserve your seat. Eventbrite registration is encouraged to skip the sign-in process at the door.
Light refreshments will be available before the lecture at 6 p.m.

DTM Weekly Seminar Series
Sharon Xuesong Wang
Sharon Xuesong Wang, a postdoctoral fellow at DTM, will give a talk titled "Finding Terrestrial Exoplanets with Precise Radial Velocities" at 11 a.m. on Thursday, March 16, 2017, in the Greenewalt Auditorium as part of DTM's Weekly Seminar Series.
Wang received her Ph.D. in astronomy and astrophysics from The Pennsylvania State University, State College, in 2016. Her primary research interest is in detecting rocky exoplanet using radial velocities (RVs). Such detections require high RV precision, especially for rocky planets in the Habitable Zone of Sun-like stars (< 1 m/s). Wang works on pushing the RV limit beyond the current 1-2 m/s level, which is set by limitations in instrumentation, data analysis, and the understanding of astrophysical noise.
Coffee, tea, and a light breakfast will be served before the lecture at 10:30 a.m.
