Biology crowding is alleviated by lottery, additional offerings Lander and Weinbergs 7.012 enrolls hundreds fewer than two years ago September 19, 2014 Two years after their introduction, the revised introductory biology classes and lottery system associated with the classes were marked as a success by MITs biology department administrators. The 7.015 and 7.016 Introductory Biology classes were introduced in the fall of 2013 to alleviate the burden on 7.012, the first variant of introductory biology, taught by Professors Eric Lander and Robert Weinberg PhD 64. Previously, 7.012 suffered from over-enrollment and crowded lecture halls. Over 800 students enrolled in the class in the fall of 2012. The introduction of 7.015 and 7.016 redistributed the biology general institute requirement (GIR) student population. Whats more, the 7.012 class saw a general increase in the students enrolled. 451 students enrolled in 7.012 in the fall of 2013 and approximately 500 enrolled this semester, according to biology department undergraduate academic officer and associate professor, Dennis H. Kim. Students who registered for 7.012 and 7.016 were again subject to a lottery that decided their final biology placement. According to Professor Kim, students sign up for their desired class and those students who enrolled after the … Continue reading →

PUBLIC RELEASE DATE: 19-Sep-2014 Contact: Jana Smith jana.smith@ou.edu 405-325-1322 University of Oklahoma @uofoklahoma A University of Oklahoma biology professor will study multifunctional and specialized spinal cord nerve cells that control leg movements with a National Science Foundation grant in the amount of $680,000 for the four-year project. Ari Berkowitz, professor in the Department of Biology, OU College of Arts and Sciences, will focus on the differences between the multifunctional and specialized spinal cord nerve cells to understand what neurotransmitters they use and what connections they make. Berkowitz will collaborate with the University of Glasgow in Scotland to test nervous system tissue in laboratory models. "We want to understand how the central nervous system selects and generates an appropriate movement for each circumstance. The system may rely on separate neurons specialized for each type of movement or a distributed network of multifunctional neurons. Studies suggest that the spinal cord uses a combination of multifunctional and specialized interneurons, but how it does so is unknown for limb movements," said Berkowitz. "We will assess how multifunctional spinal networks produce distinct types of limb movements and determine why spinal networks require some behaviorally specialized interneurons," Berkowitz explained. "Findings from this project will reveal the … Continue reading →
