Educational researchers have long held that presenting students with clear outlines of the material covered in lectures improves their retention. Recent studies indicate that the same is true of online how-to videos, and in a paper being presented at the Association for Computing Machinery’s Conference on Computer-Supported Cooperative Work and Social Computing in March, researchers at MIT and Harvard University describe a new system that recruits viewers to create high-level conceptual outlines.
‘That addresses one of the fundamental problems with videos,’ says Juho Kim, an MIT graduate student in electrical engineering and computer science and one of the paper’s co-authors. “It’s really hard to find the exact spots that you want to watch. You end up scrubbing on the timeline carefully and looking at thumbnails. And with educational videos, especially, it’s really hard, because it’s not that visually dynamic. So we thought that having this semantic information about the video really helps. Continue reading on MIT News.

“Computer chips’ clocks have stopped getting faster. To keep delivering performance improvements, chipmakers are instead giving chips more processing units, or cores, which can execute computations in parallel. But the ways in which a chip carves up computations can make a big difference to performance. In a 2013 paper, Daniel Sanchez, the TIBCO Founders Assistant Professor in MIT’s Department of Electrical Engineering and Computer Science, and his student, Nathan Beckmann, described a system that cleverly distributes data around multicore chips’ memory banks, improving execution times by 18 percent on average while actually increasing energy efficiency.” Continue reading on MIT News.

MIT chemistry graduate student Jolene Mork examines rates of excitonic-energy transfer. Energy transfer in light-sensitive materials such as quantum dots is of interest for better solar cells, LEDs, and other devices. MIT chemistry graduate student A. Jolene Mork examines how fast energy transfers from one quantum dot to another, a phenomenon known as hopping. Mork is lead author of a Journal of Physical Chemistry paper that analyzed energy transfer in colloidal quantum dots. “It’s not looking at how far can an exciton go within a film; it is how fast does it transfer from one quantum dot to another,” she says. Mork is a fifth-year MIT graduate student in the lab of William A. Tisdale, the Charles and Hilda Roddey Career Development Professor in Chemical Engineering at MIT. Read on at MIT News.

Lead sulfide nanocrystals suitable for solar cells have a nearly one-to-one ratio of lead to sulfur atoms, but MIT researchers discovered that to make uniformly sized quantum dots, a higher ratio of lead to sulfur precursors – 24 to 1 – is better. MIT chemical engineering graduate student Mark C. Weidman developed the synthetic recipe in the lab of William A. Tisdale, the Charles and Hilda Roddey Career Development Professor in Chemical Engineering at MIT, with colleagues Ferry Prins, Rachel S. Hoffman and 2013 Summer Scholar Megan Beck. Uniformity of size can promote long exciton diffusion lengths in lead sulfide (PbS) quantum-dot films, Weidman says.
Usually quantum dots are synthesized as a colloid, with particles suspended in a liquid. If the quantum dots are all of the same size, they can self-assemble into an ordered lattice. “If they are monodisperse enough, it’s the thermodynamically favored state,” Weidman explains.

Fei Chen and Paul Tillberg are lead authors of paper on enlarging brain tissue samples. Beginning with the invention of the first microscope in the late 1500s, scientists have been trying to peer into preserved cells and tissues with ever-greater magnification. The latest generation of so-called “super-resolution” microscopes can see inside cells with resolution better than 250 nanometers. A team of researchers from MIT has now taken a novel approach to gaining such high-resolution images: Instead of making their microscopes more powerful, they have discovered a method that enlarges tissue samples by embedding them in a polymer that swells when water is added. This allows specimens to be physically magnified, and then imaged at a much higher resolution. This technique, which uses inexpensive, commercially available chemicals and microscopes commonly found in research labs, should give many more scientists access to super-resolution imaging, the researchers say.

For household robots ever to be practical, they’ll need to be able to recognize the objects they’re supposed to manipulate. But while object recognition is one of the most widely studied topics in artificial intelligence, even the best object detectors still fail much of the time.
Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory believe that household robots should take advantage of their mobility and their relatively static environments to make object recognition easier, by imaging objects from multiple perspectives before making judgments about their identity. Matching up the objects depicted in the different images, however, poses its own computational challenges.
In a paper appearing in a forthcoming issue of the International Journal of Robotics Research, the MIT researchers show that a system using an off-the-shelf algorithm to aggregate different perspectives can recognize four times as many objects as one that uses a single perspective, while reducing the number of misidentifications.

The immune system is a complex network of many different cells working together to defend against invaders. Successfully fighting off an infection depends on the interactions between these cells. A new device developed by MIT engineers offers a much more detailed picture of that cellular communication. Using this device, which captures pairs of cells and collects data on each as they interact with each other, the researchers have already learned more about how T cells — major players in the immune response — become activated during infection.
The device is based on microfluidic technology developed by Joel Voldman, an MIT professor of electrical engineering and computer science (EECS), in 2009. His team used that earlier version to fuse adult cells with embryonic stem cells, allowing the researchers to observe the genetic reprogramming that occurred in these hybrids.

A team of researchers has built an array of light detectors sensitive enough to register the arrival of individual light particles, or photons, and mounted them on a silicon optical chip. Such arrays are crucial components of devices that use photons to perform quantum computations.
Single-photon detectors are notoriously temperamental: Of 100 deposited on a chip using standard manufacturing techniques, only a handful will generally work. In a paper appearing today in Nature Communications, the researchers at MIT and elsewhere describe a procedure for fabricating and testing the detectors separately and then transferring those that work to an optical chip built using standard manufacturing processes.
In addition to yielding much denser and larger arrays, the approach also increases the detectors’ sensitivity. In experiments, the researchers found that their detectors were up to 100 times more likely to accurately register the arrival of a single photon than those found in earlier arrays. Read on at MIT News as graduate student and first author on the new paper, Faraz Najafi, talks more about building the detectors.

Sixty-six million years ago, an asteroid more than five miles wide smashed into the Earth at 70,000 miles per hour, instantly vaporizing upon impact. The strike obliterated most terrestrial life, including the dinosaurs, in a geological instant: Heavy dust blocked out the sun, setting off a cataclysmic chain of events from the bottom of the food chain to the top, killing off more than three-quarters of Earth’s species — or so the popular theory goes.
But now scientists at MIT and elsewhere have found evidence that a major volcanic eruption began just before the impact, possibly also playing a role in the extinction.
The team, including graduate student Michael Eddy, precisely dated rocks from the Deccan Traps — a region of west-central India that preserves remnants of one of the largest volcanic eruptions on Earth. Based on their analysis, the researchers determined that the eruption began 250,000 years before the asteroid strike and continued for 500,000 years after the giant impact, spewing a total of 1.5 million square kilometers of lava. The immense and long-lasting volcanism may have released dangerous levels of volatile chemicals into the air, poisoning the atmosphere and oceans. Read more at MIT News.

MIT chemists have devised a new way to wirelessly detect hazardous gases and environmental pollutants, using a simple sensor that can be read by a smartphone. These inexpensive sensors could be widely deployed, making it easier to monitor public spaces or detect food spoilage in warehouses. Using this system, the researchers have demonstrated that they can detect gaseous ammonia, hydrogen peroxide, and cyclohexanone, among other gases.
“The beauty of these sensors is that they are really cheap. You put them up, they sit there, and then you come around and read them. There’s no wiring involved. There’s no power,” says Timothy Swager, the John D. MacArthur Professor of Chemistry at MIT. “You can get quite imaginative as to what you might want to do with a technology like this.”
Swager is the senior author of a paper describing the new sensors in the Proceedings of the National Academy of Sciences the week of Dec. 8. Chemistry graduate student Joseph Azzarelli is the paper’s lead author; other authors are postdoc Katherine Mirica and former MIT postdoc Jens Ravnsbaek. Continue reading on MIT News.

Using a gene-editing system originally developed to delete specific genes, MIT researchers have now shown that they can reliably turn on any gene of their choosing in living cells. This new application for the CRISPR/Cas9 gene-editing system should allow scientists to more easily determine the function of individual genes, according to Feng Zhang, the W.M. Keck Career Development Professor in Biomedical Engineering in MIT’s Departments of Brain and Cognitive Sciences and Biological Engineering, and a member of the Broad Institute and MIT’s McGovern Institute for Brain Research.
This approach also enables rapid functional screens of the entire genome, allowing scientists to identify genes involved in particular diseases. In a study published in the Dec. 10 online edition of Nature, Zhang and colleagues identified several genes that help melanoma cells become resistant to a cancer drug. Silvana Konermann, a graduate student in Zhang’s lab, and Mark Brigham, a McGovern Institute postdoc, are the paper’s lead authors. Continue reading on MIT News.

Computers are good at identifying patterns in huge data sets. Humans, by contrast, are good at inferring patterns from just a few examples. In a paper appearing at the Neural Information Processing Society’s conference next week, MIT researchers present a new system that bridges these two ways of processing information, so that humans and computers can collaborate to make better decisions.
The system learns to make judgments by crunching data but distills what it learns into simple examples. In experiments, human subjects using the system were more than 20 percent better at classification tasks than those using a similar system based on existing algorithms. In particular, Shah and her colleagues — her student Been Kim, whose PhD thesis is the basis of the new paper, and Cynthia Rudin, an associate professor of statistics at the MIT Sloan School of Management — were trying to augment a type of machine learning known as “unsupervised.” Continue reading on MIT News.

Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined.
A team of researchers at MIT has now come up with a way of greatly reducing that unpredictability, introducing a device that could ultimately allow such circuits to behave nearly as predictably as their electronic counterparts. The findings are published this week in the journal Nature Biotechnology, in a paper by associate professor of mechanical engineering Domitilla Del Vecchio and professor of biological engineering Ron Weiss.
The lead author of the paper is Deepak Mishra, an MIT graduate student in biological engineering. Other authors include recent master’s students Phillip Rivera in mechanical engineering and Allen Lin in electrical engineering and computer science.

A new way of switching the magnetic properties of a material using just a small applied voltage, developed by researchers at MIT and collaborators elsewhere, could signal the beginning of a new family of materials with a variety of switchable properties, the researchers say. The technique could ultimately be used to control properties other than magnetism, including reflectivity or thermal conductivity, they say. The first application of the new finding is likely to be a new kind of memory chip that requires no power to maintain data once it’s written, drastically lowering its overall power needs. This could be especially useful for mobile devices, where battery life is often a major limitation.
The findings were published this week in the journal Nature Materials by MIT doctoral student Uwe Bauer, associate professor Geoffrey Beach, and six other co-authors. Beach, the Class of ’58 Associate Professor of Materials Science and Engineering, says the work is the culmination of Bauer’s PhD thesis research on voltage-programmable materials. The work could lead to a new kind of nonvolatile, ultralow-power memory chips, Beach says. Continue reading on MIT News.

A group at MIT and Draper Laboratory has come up with a new approach to atomic timekeeping that may enable more stable and accurate portable atomic clocks, potentially the size of a Rubik’s cube. The group has outlined its approach in the journal Physical Review A. While chip-sized atomic clocks (CSACs) are commercially available, the researchers say these low-power devices — about the size of a matchbox — drift over time, and are less accurate than fountain clocks, the much larger atomic clocks that set the world’s standard. However, while fountain clocks are the most precise timekeepers, they can’t be made portable without losing stability.
“You could put one in a pickup truck or a trailer and drive it around with you, but I’m guessing it won’t deal very well with the bumps on the road,” says co-author Krish Kotru, a graduate student in MIT’s Department of Aeronautics and Astronautics. “We have a path toward making a compact, robust clock that’s better than CSACs by a couple of orders of magnitude, and more stable over longer periods of time.” Continue reading on MIT News.

Andrea Ippolito, a second-year graduate student in the Engineering Systems Division, began her career at Boston Scientific after getting bachelor’s and master’s degrees in biomedical engineering from Cornell University. Back then, she worked on drug-coated medical devices and studied how they interfaced with the surrounding cells of a patient. She liked working on those systems, but also began fostering an interest in health care engineering on a more macroscopic scale: Rather than one device, one human, or one interface, Ippolito wanted to look at the entire health care ecosystem.
Ippolito’s initial research focused on the use of “telehealth” — treatment via video chat — and in particular on the treatment of post-traumatic stress disorder (PTSD) within military health systems. The problem is that when members of the military return from deployment, they often do so in large numbers. As a result, the health care providers that administer PTSD screenings are overwhelmed with work. Telehealth treatment could make it easier to spread out workloads for overall better care and more predictable scheduling. It could also enable the standardization of certain health care best practices, a boon for a complex health care network like that of the U.S. military. Continue reading on MIT News.

MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications such as sensors for environmental and medical monitoring. The new strategy, described in the Nov. 13 issue of the journal Science, overcomes several limitations of existing methods for storing memory in bacterial genomes, says Lu, the paper’s senior author. Those methods require a large number of genetic regulatory elements, limiting the amount of information that can be stored.
The earlier efforts are also limited to digital memory, meaning that they can record only all-or-nothing memories, such as whether a particular event occurred. Lu and graduate student Fahim Farzadfard, the paper’s lead author, set out to create a system for storing analog memory, which can reveal how much exposure there was, or how long it lasted. To achieve that, they designed a “genomic tape recorder” that lets researchers write new information into any bacterial DNA sequence. Continue reading on MIT News.

With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation. In many popular applications — video rendering, for instance — users probably wouldn’t notice the difference, and it could significantly improve energy efficiency.
At this year’s Object-Oriented Programming, Systems, Languages and Applications (OOPSLA) conference, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory presented a new system that lets programmers identify sections of their code that can tolerate a little error. The system then determines which program instructions to assign to unreliable hardware components, to maximize energy savings while still meeting the programmers’ accuracy requirements. […]
“One of the observations from all of our previous research was that usually, the computations we analyzed spent most of their time on one or several functions that were really computationally intensive,” says Sasa Misailovic, a graduate student in electrical engineering and computer science and lead author on the new paper.

In a darkened, hangar-like space inside MIT’s Building 41, a small, Roomba-like robot is trying to make up its mind. Standing in its path is an obstacle — a human pedestrian who’s pacing back and forth. As the robot considers its options, its “thoughts” are projected on the ground: A large pink dot appears to follow the pedestrian — a symbol of the robot’s perception of the pedestrian’s position in space. Lines, each representing a possible route for the robot to take, radiate across the room in meandering patterns and colors, with a green line signifying the optimal route. The lines and dots shift and adjust as the pedestrian and the robot move.
This new visualization system combines ceiling-mounted projectors with motion-capture technology and animation software to project a robot’s intentions in real time. The researchers have dubbed the system “measurable virtual reality (MVR) — a spin on conventional virtual reality that’s designed to visualize a robot’s “perceptions and understanding of the world,” says Ali-akbar Agha-mohammadi, a postdoc in MIT’s Aerospace Controls Lab. The system was developed by Shayegan Omidshafiei, a graduate student, and Agha-mohammadi. Read more on MIT News.

All around the planet, high-frequency climate observatories are collecting atmospheric data around the clock as part of the Advanced Global Atmospheric Gases Experiment (AGAGE), a 35-year-old project to study emissions and climate change. But there’s one problem: Despite a network of observatories that covers much of the globe, AGAGE lacks data on Africa — the world’s second-largest continent. That’s something that Jimmy Gasore, along with other scientists, is trying to change. Gasore, a fourth-year graduate student in MIT’s Department of Earth, Atmospheric and Planetary Sciences under Ronald G. Prinn, the TEPCO Professor of Atmospheric Science, is working with research scientist Katherine Potter to build the first high-frequency climate observatory in all of Africa.

Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with cancer. However, sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process. MIT researchers have now developed a new way to model the effects of these genetic mutations in mice. Their approach, based on the genome-editing technique known as CRISPR, is much faster than existing strategies, which require genetically engineering mice that carry the cancerous mutations. Led by Papagiannakopoulos [a postdoc at MIT’s Koch Institute for Integrative Cancer Research], graduate student Francisco Sanchez-Rivera, the paper’s other lead author, and Koch Institute director Tyler Jacks, the paper’s senior author, the team used CRISPR to accurately reproduce the effects of two well-known lung cancer genes.

Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today’s chips, an attractive trait given the increasing power consumption of the massive data centers that power the Internet’s most popular sites. In the latest issue of the journal Nano Letters, MIT researchers present a new circuit design that could make simple superconducting devices much cheaper to manufacture. And while the circuits’ speed probably wouldn’t top that of today’s chips, they could solve the problem of reading out the results of calculations performed with Josephson junctions.
The MIT researchers — Adam McCaughan, a graduate student in electrical engineering, and his advisor, professor of electrical engineering and computer science Karl Berggren — call their device the nanocryotron, after the cryotron, an experimental computing circuit developed in the 1950s by MIT professor Dudley Buck.

The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that’s much saltier than seawater, after leaching salts from rocks deep below the surface. Now researchers at MIT and in Saudi Arabia say they have found an economical solution for removing the salt from this water. The new analysis appears this week in the journal Applied Energy, in a paper co-authored by MIT professor John Lienhard, postdoc Ronan McGovern, and four others. The research team also included graduate student Adam Weiner, graduate student Lige Sun, and undergraduate Chester Chambers at MIT, and Professor Syed Zubair at KFUP. Continue reading on MIT News.

Human beings have a remarkable ability to make inferences based on their surroundings. Is this area safe? Where might I find a parking spot? Such decisions require us to look beyond our “visual scene” and weigh an exceedingly complex set of understandings and real-time judgments. This begs the question: Can we teach computers to “see” in the same way? And once we teach them, can they do it better than we can? The answers are “yes” and “sometimes,” according to research out of MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL). Researchers have developed an algorithm that can look at a pair of photos and outperform humans in determining things like which scene has a higher crime rate, or is closer to a McDonald’s restaurant. To create the algorithm, the team — which included PhD students Aditya Khosla, Byoungkwon An, and Joseph Lim, as well as CSAIL principal investigator Antonio Torralba — trained the computer on a set of 8 million Google images from eight major U.S. cities that were embedded with GPS data on crime rates and McDonald’s locations. They then used deep-learning techniques to help the program teach itself how different qualities of the photos correlate. Continue reading on MIT News.

Last week, at the International Conference on Intelligent Robots and Systems, MIT researchers unveiled an oval-shaped submersible robot, a little smaller than a football, with a flattened panel on one side that it can slide along an underwater surface to perform ultrasound scans. Originally designed to look for cracks in nuclear reactors’ water tanks, the robot could also inspect ships for the false hulls and propeller shafts that smugglers frequently use to hide contraband. “It’s very expensive for port security to use traditional robots for every small boat coming into the port,” says Sampriti Bhattacharyya, a graduate student in mechanical engineering, who designed the robot together with her advisor, Ford Professor of Engineering Harry Asada. “If this is cheap enough — if I can get this out for $600, say — why not just have 20 of them doing collaborative inspection? And if it breaks, it’s not a big deal. It’s very easy to make.” Continue reading on MIT News.

School kids at soccer practice could use solar panels lying out in the field to charge their smartphones. A mix-in for concrete could keep buildings cooler longer, cutting the cost of air conditioning. A gel that dries to a crisp could soak up water and swell, transforming into a single-layer, mess-free base on which you can grow a garden indoors. These are the visions of a better world from emerging engineers tackled at MADMEC, the annual design competition hosted by the Department of Materials Science and Engineering at MIT.

Last week, at the International Conference on Intelligent Robots and Systems, MIT researchers unveiled an oval-shaped submersible robot, a little smaller than a football, with a flattened panel on one side [so] that it can slide along an underwater surface to perform ultrasound scans.
Originally designed to look for cracks in nuclear reactors’ water tanks, the robot could also inspect ships for the false hulls and propeller shafts that smugglers frequently use to hide contraband. Because of its small size and unique propulsion mechanism — which leaves no visible wake — the robots could, in theory, be concealed in clumps of algae or other camouflage. Fleets of them could swarm over ships at port without alerting smugglers and giving them the chance to jettison their cargo.
“It’s very expensive for port security to use traditional robots for every small boat coming into the port,” says Sampriti Bhattacharyya, a graduate student in mechanical engineering, who designed the robot together with her advisor, Ford Professor of Engineering Harry Asada.

Researchers at MIT and Northeastern University have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port. The sensor is an adaptation of a technology called GelSight, which was developed by the lab of Edward Adelson, the John and Dorothy Wilson Professor of Vision Science at MIT, and first described in 2009. The new sensor is small enough to fit on a robot’s gripper and its processing algorithm is faster, so it can give the robot feedback in real time. The researchers presented their results at the International Conference on Intelligent Robots and Systems this week. The MIT team — which consists of Adelson; first author Rui Li, a PhD student; Wenzhen Yuan, a master’s student; and Mandayam Srinivasan, a senior research scientist in the Department of Mechanical Engineering — designed and built the sensor.

For future astronauts, the process of suiting up may go something like this: Instead of climbing into a conventional, bulky, gas-pressurized suit, an astronaut may don a lightweight, stretchy garment, lined with tiny, musclelike coils. She would then plug in to a spacecraft’s power supply, triggering the coils to contract and essentially shrink-wrap the garment around her body. Now MIT researchers are one step closer to engineering such an active, “second-skin” spacesuit: Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT, and her colleagues have engineered active compression garments that incorporate small, springlike coils that contract in response to heat. The coil design was conceived by Bradley Holschuh, a postdoc in Newman’s lab. Holschuh and Newman, along with graduate student Edward Obropta, detail the design in the journal IEEE/ASME: Transactions on Mechatronics. Continue reading on MIT News.

Over the last few years, researchers at MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) have developed biologically inspired robots designed to fly like falcons, perch like pigeons, and swim like swordfish. The natural next step? Slithering like snakes. At this week’s IEEE/RSJ International Conference on Intelligent Robots and Systems, CSAIL researchers will present their work to develop a soft robotic arm, inspired by the design of octopus tentacles, that can snake through a pipelike environment without a human operator. In the case of CSAIL’s robot arm, the research team — which is led by doctoral candidate Andrew Marchese and also includes Rus and PhD student Robert Katzschmann — developed complex algorithms to determine the body curvature needed for the robot to make a diversity of different motions.

Speed and agility are hallmarks of the cheetah: The big predator is the fastest land animal on Earth, able to accelerate to 60 mph in just a few seconds. As it ramps up to top speed, a cheetah pumps its legs in tandem, bounding until it reaches a full gallop. Now MIT researchers have developed an algorithm for bounding that they’ve successfully implemented in a robotic cheetah — a sleek, four-legged assemblage of gears, batteries, and electric motors that weighs about as much as its feline counterpart. The team recently took the robot for a test run on MIT’s Killian Court, where it bounded across the grass at a steady clip. Sangbae Kim, an associate professor of mechanical engineering, and his colleagues — research scientist Hae-Won Park and graduate student Meng Yee Chuah — will present details of the bounding algorithm this month at the IEEE/RSJ International Conference on Intelligent Robots and Systems in Chicago.

Friends and colleagues were aware, at some level, that Nick Roy, a researcher in MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), had been using his sabbatical to take on some sort of robotics-related role at Google. But few people knew the full scope of his work until this past week, when Google X — the infamous idea incubator known for Google Glass, self-driving cars, and wireless hot-air balloons — unveiled a video introducing Project Wing, an ambitious delivery-drone initiative that Roy has overseen for the past two years. Project Wing lined up nicely with Roy’s work as head of CSAIL’s Robust Robotics Group, which focuses in part on sensing, planning, and controlling unmanned vehicles in environments without GPS. He even brought on board a handful of key MIT collaborators, including recent graduates Abraham Bachrach PhD ’13 and Adam Bry SM ’11, whose state-estimation algorithms have drastically improved unmanned aerial vehicle (UAV) navigation in indoor spaces.

In the 21st century, design contests have emerged as a way to make rapid progress on tough computational problems. The million-dollar Netflix Prize, which sought to improve Netflix’s movie recommendation algorithm, is probably the most high-profile example. But similar, if lower-stakes, contests have addressed problems in computer vision, medical-data analysis, and weather prediction. In 2012, two PhD students in the lab of Hari Balakrishnan, the Fujitsu Professor of Computer Science and Engineering, hatched the idea of bringing that type of contest into the classroom. “It was a privilege to be able to work with 40 MIT students and to harvest their creativity,” says Anirudh Sivaraman, one of the graduate students who helped design the contest, and first author on the paper published last month. “You don’t get this kind of access to really smart people working on a problem in a focused manner elsewhere.” Continue reading this article on MIT News.

If you’ve seen a sci-fi flick with autonomous robots in the last 40 years, you may be wary of giving robots any semblance of control. But new research coming out of MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) suggests that letting robots have control over human tasks in manufacturing is not just more efficient — it’s actually preferred by workers. “In our research we were seeking to find that sweet spot for ensuring that the human workforce is both satisfied and productive,” says project lead Matthew Gombolay, a PhD student at CSAIL. “We discovered that the answer is to actually give machines more autonomy, if it helps people to work together more fluently with robot teammates.” Continue reading this article on MIT News.

Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water — and much of that area is not served by an electric grid that could run conventional reverse-osmosis desalination plants.
Now an analysis by MIT researchers shows that a different desalination technology called electrodialysis, powered by solar panels, could provide enough clean, palatable drinking water to supply the needs of a typical village. The study, by MIT graduate student Natasha Wright and Amos Winter, the Robert N. Noyce Career Development Assistant Professor of Mechanical Engineering, appears in the journal Desalination.

Maxime Cohen, a graduate student at the MIT Operations Research Center, could be doing just about anything now. Were he solely an altruist, Cohen might have pursued his charitable work full-time: In college, he started an organization to help French immigrants to Israel adjust to their new environment. He also worked with low-income families in Haifa, where the Technion is located, providing groceries and helping children with homework.
But instead, Cohen is at MIT, as a PhD candidate advised by Georgia Perakis, the William F. Pounds Professor of Management at the MIT Sloan School of Management. Operations research applies mathematics and engineering methods to problems typically tackled with traditional business techniques; Cohen is obsessed with using these tools to develop solutions that address industry and government concerns.

The Database Group at MIT’s Computer Science and Artificial Intelligence Laboratory has released a data-visualization tool that lets users highlight aberrations and possible patterns in the graphical display; the tool then automatically determines which data sources are responsible for which. It could be, for instance, that just a couple of faulty sensors among dozens are corrupting a very regular pattern of readings, or that a few underperforming agents are dragging down a company’s sales figures, or that a clogged vent in a hospital is dramatically increasing a few patients’ risk of infection. For his thesis work, Eugene Wu, a graduate student in electrical engineering and computer science who developed DBWipes with Madden and adjunct professor Michael Stonebraker, designed a novel “provenance tracking” system for large data sets.

PhD student Fadel Adib and MIT alumni Jinha Lee, Maria Mines Pereira, and David He have all been named on MIT Technology Review’s 35 Innovators Under 35. All 35 of these people are doing exciting work that could shape their fields for decades, but they’re solving problems in remarkably different ways. We consider some of them to be primarily Inventors; they’re immersed in building new technologies. Others we call Visionaries, because they’re showing how technologies could be put to new or better uses. Humanitarians are using technology to expand opportunities or inform public policy. Pioneers are doing fundamental work that will spawn future innovations; such breakthroughs will be taken up by tomorrow’s Entrepreneurs, people who are building new tech businesses.

A system proposed by researchers at MIT recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels that provide emissions-free power. The system is described in a paper in the journal Energy and Environmental Science, co-authored by professors Angela M. Belcher and Paula T. Hammond, graduate student Po-Yen Chen, and three others. It is based on a recent development in solar cells that makes use of a compound called perovskite — specifically, organolead halide perovskite — a technology that has rapidly progressed from initial experiments to a point where its efficiency is nearly competitive with that of other types of solar cells.

MIT engineers have fabricated a new elastic material coated with microscopic, hairlike structures that tilt in response to a magnetic field. Depending on the field’s orientation, the microhairs can tilt to form a path through which fluid can flow; the material can even direct water upward, against gravity. Each microhair, made of nickel, is about 70 microns high and 25 microns wide — about one-fourth the diameter of a human hair. The researchers fabricated an array of the microhairs onto an elastic, transparent layer of silicone. “You could coat this on your car windshield to manipulate rain or sunlight,” says Yangying Zhu, a graduate student in MIT’s Department of Mechanical Engineering. “So you could filter how much solar radiation you want coming in, and also shed raindrops. This is an opportunity for the future.” Read the full article on MIT News.

About one in four older adults suffers from chronic pain. Many of those people take medication, usually as pills. But this is not an ideal way of treating pain: Patients must take medicine frequently, and can suffer side effects, since the contents of pills spread through the bloodstream to the whole body. Now researchers at MIT have refined a technique that could enable pain medication and other drugs to be released directly to specific parts of the body — and in steady doses over a period of up to 14 months. The method uses biodegradable, nanoscale “thin films” laden with drug molecules that are absorbed into the body in an incremental process. Professor Paula Hammond and Brian Hsu PdD ’14 have been instrumental in the development.” Continue reading at MIT News.

Grad students Abe Davis (EECS) and Neal Wadhwa (18) and researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.
In other experiments, they extracted useful audio signals from videos of aluminum foil, the surface of a glass of water, and even the leaves of a potted plant. The researchers will present their findings in a paper at this year’s Siggraph, the premier computer graphics conference. “When sound hits an object, it causes the object to vibrate,” says Abe Davis, a graduate student in electrical engineering and computer science at MIT and first author on the new paper. “The motion of this vibration creates a very subtle visual signal that’s usually invisible to the naked eye. People didn’t realize that this information was there.” Continue reading at MIT News. Photo by Tess Watson.

Much artificial-intelligence research addresses the problem of making predictions based on large data sets. An obvious example is the recommendation engines at retail sites like Amazon and Netflix. But some types of data are harder to collect than online click histories —information about geological formations thousands of feet underground, for instance. And in other applications — such as trying to predict the path of a storm — there may just not be enough time to crunch all the available data. Dan Levine, an MIT graduate student in aeronautics and astronautics, and his advisor, Jonathan How, the Richard Cockburn Maclaurin Professor of Aeronautics and Astronautics, have developed a new technique that could help with both problems.

The magnets cluttering the face of your refrigerator may one day be used as cooling agents, according to a new theory formulated by MIT researchers.
The theory describes the motion of magnons — quasi-particles in magnets that are collective rotations of magnetic moments, or “spins.” In addition to the magnetic moments, magnons also conduct heat; from their equations, the MIT researchers found that when exposed to a magnetic field gradient, magnons may be driven to move from one end of a magnet to another, carrying heat with them and producing a cooling effect.
“You can pump heat from one side to the other, so you can essentially use a magnet as a refrigerator,” says Bolin Liao, a graduate student in MIT’s Department of Mechanical Engineering. “You can envision wireless cooling where you apply a magnetic field to a magnet one or two meters away to, say, cool your laptop.” Continue reading about his research on MIT News.

Harry Asada, the Ford Professor of Engineering in MIT’s Department of Mechanical Engineering and graduate student Faye Wu recently presented a paper on a robot that enhances the grasping motion of the human hand at the Robotics: Science and Systems conference in Berkeley, Calif. The robot, which the researchers have dubbed “supernumerary robotic fingers,” consists of actuators linked together to exert forces as strong as those of human fingers during a grasping motion. The device, worn around one’s wrist, works essentially like two extra fingers adjacent to the pinky and thumb. A novel control algorithm enables it to move in sync with the wearer’s fingers to grasp objects of various shapes and sizes. Wearing the robot, a user could use one hand to, for instance, hold the base of a bottle while twisting off its cap. Learn more about Wu’s research at MIT News.

In August, grad students Jonathan Perry and Amy Ousterhout will be attending the annual conference of the ACM Special Interest Group on Data Communication. The MIT researcher team will present a new network-management system that, in experiments, reduced the average queue length of routers in a Facebook data center by 99.6 percent — virtually doing away with queues. When network traffic was heavy, the average latency — the delay between the request for an item of information and its arrival — shrank nearly as much, from 3.56 microseconds to 0.23 microseconds.
Like the Internet, most data centers use decentralized communication protocols: Each node in the network decides, based on its own limited observations, how rapidly to send data and which adjacent node to send it to. Decentralized protocols have the advantage of an ability to handle communication over large networks with little administrative oversight. Continue reading at MIT News.

A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons. In the July 21 issue of Nature Communications, the researchers describe in detail the mechanism by which these nanoparticles are able to fuse with a membrane. The findings suggest possible strategies for designing nanoparticles — made from gold or other materials — that could get into cells even more easily.
“We’ve identified a type of mechanism that might be more prevalent than is currently known,” says Reid Van Lehn, an MIT graduate student in materials science and engineering and one of the paper’s lead authors. “By identifying this pathway for the first time it also suggests not only how to engineer this particular class of nanoparticles, but that this pathway might be active in other systems as well.” Continue reading about the research at MIT News.

Last year, MIT researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. The team consists of postdoc Nenad Milikov, associate professor of mechanical engineering, Evelyn Wang, former postdoc Ryan Enright, and MIT graduate Daniel Preston. Now, the researchers have demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices. This approach could lead to devices to charge cellphones or other electronics using just the humidity in the air. As a side benefit, the system could also produce clean water.

Machine learning, in which computers learn new skills by looking for patterns in training data, is the basis of most recent advances in artificial intelligence, from voice-recognition systems to self-parking cars. It’s also the technique that autonomous robots typically use to build models of their environments.
“A single computer has a very difficult optimization problem to solve in order to learn a model from a single giant batch of data, and it can get stuck at bad solutions,” says Trevor Campbell, a graduate student in aeronautics and astronautics at MIT, who wrote the new paper with his advisor, Jonathan How, the Richard Cockburn Maclaurin Professor of Aeronautics and Astronautics. “If smaller chunks of data are first processed by individual robots and then combined, the final model is less likely to get stuck at a bad solution.”

The headlines are as unavoidable as they are alarming. This year, the Centers for Disease Control and Prevention reported that 1 in 68 8-year-old children were diagnosed with some form of autism in 2010, up from 1 in 150 a decade before. No one knows exactly why that rate keeps rising. Researchers have delved into everything from mercury exposure to parental age. But Phech Colatat, who has just earned his PhD in economic sociology from MIT Sloan, thinks we’ve been looking for answers in the wrong places.

When Kelly Heber goes snorkeling in Bali, she’s not exactly vacationing. In a few minutes, she’ll be onboard a nearby boat, asking the captain if he’s seen any comeback in his fish stocks in recent years. She’ll ask how he decides if a coral reef is healthy enough to support daily visits from boatloads of tourists, and if littering and pollution pose threats.
As a PhD student in the MIT Department of Urban Studies and Planning working in the Science Impact Collaborative, Heber performs her environmental policy fieldwork in rural villages in Indonesia that are fringed by vibrant coral reefs. These reefs suffered during the period from the 1950s to the 1990s, when fishermen commonly exploded cyanide bombs in the water to kill and harvest all the fish in an area at once. Still in recovery, these “post-blast” coral reefs now attract thousands of tourists a year, generating the main source of income for village communities.

MIT graduate student Leon Dimas is no stranger to resilience: At 18, as a rising soccer star, the long-armed goalkeeper was a promising prospect who played for the youth academy of Rosenborg BK, a top-ranked Norwegian soccer club. He was set, it seemed, on a path that would allow him to pursue a professional career playing the game that was his first love. But when Dimas suffered nagging damage to a shoulder tendon, his professional prospects dimmed. Over the course of the next year, he made the decision to abandon professional soccer for good. “Once that dream broke, you wonder if you can get these kinds of feelings again,” Dimas says, “feelings of accomplishment and that someone believes in you.”
It’s fair to say that Dimas, now a doctoral student in MIT’s Department of Civil and Environmental Engineering, has bounced back. Fittingly, he is now working on creating new materials that have resilience of their own — by borrowing from the oldest blueprint around. Learn more about Leon Dimas’ research at MIT News.

Most of the robotic limbs you hear about are meant to replace arms and legs that have been lost to injury, but MIT is working on robotic limbs that are just meant to add on additional ones, giving people three or four arms so that they can get more done. Its researchers demonstrated the limbs — which they call supernumerary robotic arms — at a conference yesterday in China, and videos show that they’re already working to a basic extent. The current suit reportedly weighs just 10 pounds, but right now it seems to mainly be useful for holding light objects in place.
“Once we combine the most significant behavioral modes we are able to control the robot such that, from the wearer’s perspective, it behaves like an extension of his own body,” Baldin Llorens-Bonilla, an MIT researcher working on robotic limbs, tells IEEE Spectrum.
