Treating Diseases by Using RNAi Technology

Mon, 25 Feb 2013 18:31:29 GMT

RNA interference (RNAi) is a process in which small pieces of silencing RNA (siRNA) bind to cellular RNA, thereby shutting down the production of the encoded protein.

Nozomi Ando's Personal Story

Mon, 25 Feb 2013 18:31:28 GMT

Nozomi, a self-described artist and comic book lover, describes how her training to become a scientist was akin to that of a ninja.

Targeting Ulcer-Causing H. Pylori Bacteria

Mon, 25 Feb 2013 18:31:28 GMT

Dr. Sarah Bowman studies a protein from a pathogenic bacterium that is found in the stomach and is known to cause ulcers. She explains how the bacterium survives in the low pH environment of the stomach by using a nickel-dependent protein to buffer the acidity of its environment. Sarah envisions that taking advantage of this nickel requirement could lead to a new treatment for ulcers.

Understanding Chemotherapeutic Drug Targets

Mon, 25 Feb 2013 18:31:28 GMT

Dr. Nozomi Ando conducts research on a protein that is essential for DNA synthesis, repair and replication. She explains how this protein is in equilibrium between an active and an inactive form, and how discovering strategies to lock the protein in the inactive conformation could lead to treatments for cancer and/or could be used in the creation of new antibiotics.

Imaging Viruses with Nanoscale MRI

Mon, 25 Feb 2013 18:31:27 GMT

Ben Ofori-Okai discusses the concept of orbital degeneracy (two orbitals with the same energy) in relation to his research on nanoscale MRI (magnetic resonance imaging)

Engineering Enzyme Pathways for Biofuel Development

Mon, 25 Feb 2013 18:31:25 GMT

Jingnan Lu's research focuses on converting carbon dioxide, an environmental pollutant, into biofuel. Here she explains how she engineers a carbon-storing microorganism into a biofuel production pathway.

Conversation with Lydia Villa-Komaroff

Thu, 27 Dec 2012 08:05:47 GMT

Lydia Villa-Komaroff grew up in a large Mexican-American family in New Mexico. She received her PhD from the MIT Dept. of Biology, where she worked with David Baltimore and Harvey Lodish on Polio virus.

She did her postdoctoral training at Harvard where she also worked with Walter Gilbert on recombinant DNA. She is a founding member of SACNAS, the Society for the Advancement of Chicanos and Native Americans in Science.

She has held numerous positions in academia, both as a faculty at the University of Massachusetts Medical School, the Harvard Medical School and Northwestern University, and as a top administrator at Northwestern University and the Whitehead Institute (vice president of research and chief operating officer). She is currently chief executive officer of Cytonome, Inc. (optical cell sorting systems), a biotech company in Boston.

Part of the Conversations with Scientists series sponsored by the MIT Department of Biology and HHMI.
