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.

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)

Labeling Tumors with Quantum Dots

Mon, 25 Feb 2013 18:31:26 GMT

Quantum dots are tiny semiconductor crystals with vivid colors that can be used as visual labels in biology and medicine. Quantum dots excited by UV radiation emit light with an energy and color that is determined by the size of the quantum dot.

Darcy Wanger describes how the characteristics of atomic energy levels relate to the color of quantum dots, and how quantum dots may someday be used as markers in surgical procedures.

Tue, 22 Jan 2013 21:31:22 GMT

Researchers from MIT have now found a safe and efficient way to get large molecules through the cell membrane, by squeezing the cells through a narrow constriction that opens up tiny, temporary holes in the membrane.

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.

Where Biology and Geology Meet

Tue, 13 Nov 2012 21:30:12 GMT

Geobiologist, and Hayes Career Dev. Assoc. Professor in the Department of Earth, Atmospheric, and Planetary Sciences, Tanja Bosak studies microbial fossils to understand the parallel evolution of life and the environment. She also undertakes laboratory experiments on modern microbes to test how they shape rocks and why microbes produce unique polycyclic lipid compounds that can persist in sediments for billions of years.

In this video interview she describes how her research contributes to unravelling the co-evolution of life and the environment on early Earth.

Professor Bosak, who received her Ph.D. in 2004 from CalTech, joined the EAPS faculty in 2007.

Cell division and growth rate

Mon, 06 Aug 2012 07:06:25 GMT

MIT researchers answer a longstanding question in biology: How do cells know when to progress through the cell cycle?

BLOSSOMS - ATP: The Fuel of Life

Thu, 02 Aug 2012 07:05:45 GMT

Teacher: Christian R. Schubert

Summary: The goal of this lesson is to introduce students who are interested in human biology and biochemistry to the subtleties of energy metabolism (typically not presented in standard biology and biochemistry textbooks) through the lens of ATP as the primary energy currency of the cell. Avoiding the details of the major pathways of energy production (such as glycolysis, the citric acid cycle, and oxidative phosphorylation), this lesson is focused exclusively on ATP, which is truly the fuel of life.
