Lewis reveals brain-wave patterns detailing consciousness during anesthesia
A new study from MIT and Massachusetts General Hospital (MGH) reveals, for the first time, what happens inside the brain as patients lose consciousness during anesthesia. By monitoring brain activity as patients were given a common anesthetic, the researchers were able to identify a distinctive brain activity pattern that marked the loss of consciousness. This pattern, characterized by very slow oscillation, corresponds to a breakdown of communication between different brain regions, each of which experiences short bursts of activity interrupted by longer silences.
“Within a small area, things can look pretty normal, but because of this periodic silencing, everything gets interrupted every few hundred milliseconds, and that prevents any communication,” says Laura Lewis, a graduate student in MIT’s Department of Brain and Cognitive Sciences (BCS) and one of the lead authors of a paper describing the findings in the Proceedings of the National Academy of Sciences this week. This pattern may help anesthesiologists to better monitor patients as they receive anesthesia, preventing rare cases where patients awaken during surgery or stop breathing after excessive doses of anesthesia drugs.

Chasin mines physicians’ notes for medical insights
In the last 10 years, it’s become far more common for physicians to keep records electronically. Those records could contain a wealth of medically useful data: hidden correlations between symptoms, treatments and outcomes, for instance, or indications that patients are promising candidates for trials of new drugs. Much of that data, however, is buried in physicians’ freeform notes. One of the difficulties in extracting data from unstructured text is what computer scientists call word-sense disambiguation. In a physician’s notes, the word “discharge,” for instance, could refer to a bodily secretion — but it could also refer to release from a hospital. The ability to infer words’ intended meanings makes it much easier for computers to find useful patterns in mountains of data.
Graduate student Rachel Chasin is a co-authour of the paper concerning algorithmically distinguishing words with multiple possible meanings in medical records; postdoc Anna Rumshisky led the research with Peter Szolovits, MIT professor of computer science and engineering and health science and technology, and Özlem Uzuner, a research affiliate.

Paek determines that paintballs may deflect an incoming asteroid
In the event that a giant asteroid is headed toward Earth, you’d better hope that it’s blindingly white. A pale asteroid would reflect sunlight — and over time, this bouncing of photons off its surface could create enough of a force to push the asteroid off its course. How might one encourage such a deflection? The answer, according to an MIT graduate student: with a volley or two of space-launched paintballs.
Sung Wook Paek, a graduate student in MIT’s Department of Aeronautics and Astronautics, says if timed just right, pellets full of paint powder, launched in two rounds from a spacecraft at relatively close distance, would cover the front and back of an asteroid, more than doubling its reflectivity, or albedo. The initial force from the pellets would bump an asteroid off course; over time, the sun’s photons would deflect the asteroid even more. Read the rest of the article on MITnews.

Martell uses protein-labeling to visualize molecules inside cells
The glowing green molecule known as green fluorescent protein (GFP) has revolutionized molecular biology. When GFP is attached to a particular protein inside a cell, scientists can easily identify and locate it using fluorescence microscopy. However, GFP can’t be used with electron microscopy, which offers much higher resolution than fluorescence microscopy. Chemists from MIT have now designed a GFP equivalent for electron microscopy — a tag that allows scientists to label and visualize proteins with unprecedented clarity.
“With things that may appear only a few pixels across by fluorescence microscopy — for example, a mitochondrion — you can’t make out any of the internal features. But with electron microscopy it’s very easy to discern the intricate internal structures,” says Jeff Martell, a graduate student in chemistry at MIT and lead author of a paper describing the new tag in the Oct. 21 online edition of Nature Biotechnology. The new tag could help scientists pinpoint the locations of many cell proteins, providing new insight into those proteins’ functions, according to the researchers.

Paxson helps discover a better way to shed water
Condensers are a crucial part of today’s power generation systems: About 80 percent of all the world’s powerplants use them to turn steam back to water after it comes out of the turbines that turn generators. They are also a key element in desalination plants, a fast-growing contributor to the world’s supply of fresh water. Now, a new surface architecture designed by researchers at MIT holds the promise of significantly boosting the performance of such condensers. The research is described in a paper just published online in the journal ACS Nano by MIT postdoc Sushant Anand; Kripa Varanasi, the Doherty Associate Professor of Ocean Utilization; and graduate student Adam Paxson, postdoc Rajeev Dhiman and research affiliate Dave Smith, all of Varanasi’s research group at MIT.
The key to the improved hydrophobic (water-shedding) surface is a combination of microscopic patterning — a surface covered with tiny bumps or posts just 10 micrometers (millionths of a meter) across, about the size of a red blood cell — and a coating of a lubricant, such as oil. The tiny spaces between the posts hold the oil in place through capillary action, the researchers found. Continue reading the article on MITnews.

Ehrenberg discovers new metamaterial lens
In many respects, metamaterials are supernatural. These manmade materials, with their intricately designed structures, bend electromagnetic waves in ways that are impossible for materials found in nature. Scientists are investigating metamaterials for their potential to engineer invisibility cloaks — materials that refract light to hide an object in plain sight — and “super lenses,” which focus light beyond the range of optical microscopes to image objects at nanoscale detail. Researchers at MIT have now fabricated a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision. The concave lens exhibits a property called negative refraction, bending electromagnetic waves — in this case, radio waves — in exactly the opposite sense from which a normal concave lens would work.
For Isaac Ehrenberg, an MIT graduate student in mechanical engineering, the device evokes an image from the movie “Star Wars”: the Death Star, a space station that shoots laser beams from a concave dish, the lasers converging to a point to destroy nearby planets. While the researchers’ fabricated lens won’t be blasting any planetary bodies in the near future, Ehrenberg says there are other potential applications for the device, such as molecular and deep-space imaging.

Sung is speeding algorithms by shrinking data
In computer science, the buzzword of the day is “big data.” The proliferation of cheap, Internet-connected sensors — such as the GPS receivers, accelerometers and cameras in smartphones — has meant an explosion of information whose potential uses have barely begun to be explored. In large part, that’s because processing all that data can be prohibitively time-consuming.
Most computer scientists try to make better sense of big data by developing ever-more-efficient algorithms. But in a paper presented this month at the Association for Computing Machinery’s International Conference on Advances in Geographic Information Systems, MIT researchers take the opposite approach, describing a novel way to represent data so that it takes up much less space in memory but can still be processed in conventional ways. While promising significant computational speedups, the approach could be more generally applicable than other big-data techniques, since it can work with existing algorithms.
EECS graduate student Cynthia Sung is the paper’s third author, along with postdoc Dan Feldman and Daniela Rus, the director of MIT’s Computer Science and Artificial Intelligence Laboratory. Read the rest of the article on MITnews.

A fond farewell to Sidney-Pacific and Ashdown Housemasters
Dean for Student Life Chris Colombo announced that next June, Sidney-Pacific and Ashdown House, two of MIT’s graduate communities, will say farewell to their long-time Housemasters, Roger and Dottie Mark and Terry and Ann Orlando. “Over the last decade, MIT has built a remarkable graduate community in the Northwest campus. At the center of that community have been the Marks and the Orlandos,” Colombo says. “We are honored and grateful for the truly wonderful impact these Housemasters have had on our students.”
MIT Housemasters are an integral part of the residential experience at MIT. They are faculty members who reside in the undergraduate and graduate residence halls, and serve as mentors, neighbors and intellectual leaders for the communities. Housemasters work to advise individual students, advocate for the House, and foster community life. “Housemasters serve a critical function in the graduate student community,” said Dean for Graduate Education Christine Ortiz. “When students leave the classroom or lab, it is the Housemasters who can encourage interaction among students, as well as the formation of friendships so students can get to know one another personally.” Read the rest of the story on MIT News.

Celiker discovers survival edge in cooperating yeast cells
Many species exhibit cooperative survival strategies — for example, sharing food or alerting other individuals when a predator is nearby. However, there are almost always freeloaders in the population who will take advantage of cooperators. This can be seen even among microbes such as yeast, where “cheaters” consume food produced by their neighbors without contributing any of their own. In light of this, evolutionary biologists have long wondered why cooperation remains a viable survival strategy, since there will always be others who cheat. Now, MIT physicists have found a possible answer to this question: Among yeast, cooperative members of the population actually have a better chance of survival than cheaters when a competing species is introduced into an environment. Hasan Celiker, an MIT graduate student in electrical engineering and computer science, is the paper’s lead author. Continue reading the article on MITnews.

A Day in the Life of a Digital Humanities Postdoc
- Plan and teach class on Walter Benjamin’s “The Work of Art in the Age of Mechanical Reproduction”
- Work on article about teaching with Wikipedia
- Present an hour-long demonstration of Eighteenth-Century Collections Online to an upper-division English class based on their course materials
- Train undergraduates to use Omeka so they can support faculty and students using it in a variety of courses
This is a typical day for me and illustrates why I relish my job as a digital humanities postdoc at Occidental College. It offers everything I want in a digital humanities position: time for research, flexibility to experiment with my teaching, and the opportunity to spread the word about how technology can invigorate teaching and revolutionize research in the humanities. Postdocs are relatively rare in the humanities compared to the sciences, and postdocs at liberal arts colleges are even rarer. Because digital humanities postdocs at liberal arts institutions are so new, they pose unique opportunities and challenges that highlight important questions about the structure of the academy. In this post, I will discuss how my liminality allows me a degree of freedom unusual even for academia, but also privileges skills that I teach myself rather than the ones I learned in graduate school.

Working Hours for Graduate Students
One thing any academic recognizes is the fact that there is always more work to be done. There’s always another article to read, another experiment to run, another set of data to code, or another archive to consult. And so this leads, reasonably enough, to some anxiety about just how much work one should be doing at any given moment. Graduate students, especially newer ones, understandably need guidance in learning to recognize the norms and values of the academy. And so, a few weeks ago, an unnamed department in astronomy apparently sent this message (via AstroBetter, where there are great comments, too) to all the graduate students in their program… Continue reading the article on The Chronicle of Higher Education. photo by Flickr user Skiwalker79

Bitten by the Online Bug
The label “online lecturer” used to bother me. You didn’t see teachers in a traditional classroom calling themselves “in-the-flesh lecturers” or “face-to-face lecturers.” I feared that if I became an online lecturer, my colleagues might start to question the quality of my teaching or my reputation—as though the “online” bit would make what I did a little less important. Or a little less, well, good. Then I finished teaching my first online course and I switched sides. “Online lecturer” is simply the best way to describe what I do and how I teach, and I now find myself proud of the title.

Mind and hand: A fencer takes on MIT Sloan’s MSMS Program
At the age of 18, Valentina Rizzati, MSMS ’13, had to choose between fencing and economics. An accomplished fencer from Ferrara, Italy, Rizzati won regional and inter-regional competitions and placed fifth at an international fencing competition. However, like most athletes, Rizzati realized she couldn’t keep up with a competitive sport forever. Writing an economics paper in high school sparked her interest in the subject, and it’s what eventually led her to MIT Sloan. “For my last year of my master’s I wanted to attend a school with a diverse and unique curriculum and student body, and I knew that I would find that at MIT Sloan.” Read the rest of the article on News@MITSloan. photo courtesy of Valentina Rizzati

The Dissertation Defense: We’re Doing Something Right
I never had a dissertation defense. My department had abolished them sometime before I arrived as a graduate student, and I considered myself lucky compared with friends at other universities who had to endure what I imagined as a painful ordeal. So when the time came, my two faculty readers signed a form approving my dissertation, and I walked the bound manuscript over to the registrar and submitted it. That was that. The first defense I ever attended was as a professor. Only then did I realize what I had missed. Continue reading the article in The Chronicle of Higher Education. photo by Brian Taylor
