Duke iGEM 2014 team with faculty advisors Nick Buchler, front left, and Charlie Gersbach, front right. Mike is behind Dr. Gersbach. by Anika Radiya-Dixit The International Genetically Engineered Machine (iGEM) competition is dedicated to education for students interested in the advancement of synthetic biology, in other words, taking engineering principles and applying them to natural sciences like biology. Students in the competition explored using a gene or series of genes from E.coli bacteria to create biological devices for applications such as dissolving plastic or filtering water. In November 2014, the Duke iGEM team took part in the annual competition in Boston, proudly leaving with a gold medal on their work in 3D printing technology and DNA synthesis protocol. This week, I contacted the iGEM team and had the opportunity to talk with one of the members, Mike Zhu, about his experience in the competition. Mike is currently a junior from Northern California studying Biomedical Engineering and Computer Science. He is enthusiastic about researching how biology and computer science interact, and is conducting research with Dr. John Reif on DNA technology. Mike is also involved with the Chinese Dance team, and enjoys cooking, eating, and sleeping. Below is an edited transcript … Continue reading →

University San Diego Assistant Biology Professor Adam Siepielski co-lead a study documenting recent changes in animal mass mortality events, including certain species of sea stars, which he is holding at USD in San Diego on Tuesday. Mass animal die-offs have become more common, and often more severe, in recent years, according to researchers from the University of San Diego, Yale University and UC Berkeley. Their study, published this week in the Proceedings of the National Academy of Sciences, analyzed 727 scientific reports of mass mortalities that affected 2,407 animal populations. The die-offs increased by about one event per year during the 70 years between 1940 and 2010, and the scale of deaths escalated for some creatures, the researchers said. The new analysis helps explain what happens when millions of animals perish in a single blow, and sheds more light on the rapid changes in biodiversity that scientists have previously reported. This sort of analysis will help clarify the relation between mass mortality events and global extinction events, said study co-author Samuel Fey, a postdoctoral research fellow in ecology and evolutionary biology at Yale. The examination began when co-author Adam Siepielski, an assistant professor of biology at the University of San … Continue reading →
