Greg SteinBrecher—The Tech
The candidates for UA president and vice president participate in a debate in the student center on Sunday. Electronic voting will begin next Tuesday and end next Thursday; paper balloting will occur next Friday. For a video of the full debate, see http://tech.mit.edu/V130/N11/uadebate/video.html | |
Fractal globule model Lieberman-Aiden’s new technique for creating 3-D genomic maps (Hi-C), gave him evidence him to theorize that the structure of the human genome forms a “fractal globule.” Here the genome forms super-dense, knot-free “globules of globules of globules,” which allows for regions in 1-D to also occur nearby in 3-D. Nearby regions are indicated using similar colors. | |
Equilibrium globule model The “equilibrium globule” is an older model that describes how the genome might exist in three-dimensions. Unlike in the “fractal globule” model, here individual strands are highly entangled and regions nearby along the chain are far apart in 3-D. In this image, nearby regions on a chain of DNA are indicated using similar colors. |

Peano curves Discovered by Giuseppe Peano in 1890, Peano curves are a class of one-dimensional space-filling curves that densely fill higher dimensional space. Liberman-Aiden, winner of the Lemelson-MIT Student Prize, recently published a 3-D map of the genome that suggests long stretches of DNA fold into Peano-curve–like structures. |

At the MIT Energy Conference on Saturday, United States Senator Jeff Bingaman (D-NM) speaks about the steps that the U.S. must take to achieve energy independence. The annual student-run conference focuses on technology- and policy-based solutions to global energy problems. | |
