Title: Neuron Activity in 3-D
Runtime: 2:34
Date posted: 12 years ago
Description: Researchers at MIT and the University of Vienna have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D movies of entire brains at the millisecond timescale, could help scientists discover how neuronal networks process sensory information and generate behavior.

The team used the new system to simultaneously image the activity of every neuron in the worm Caenorhabditis elegans, as well as the entire brain of a zebrafish larva, offering a more complete picture of nervous system activity than has been previously possible.

The new approach, described May 18 in Nature Methods, could also help neuroscientists learn more about the biological basis of brain disorders. "We don't really know, for any brain disorder, the exact set of cells involved," Boyden says. "The ability to survey activity throughout a nervous system may help pinpoint the cells or networks that are involved ...

Floating nuclear plants could withstand earthquakes and tsunamis

Title: Floating nuclear plants could withstand earthquakes and tsunamis
Runtime: 3:11
Date posted: 12 years ago
Description: When an earthquake and tsunami struck the Fukushima Daiichi nuclear plant complex in 2011, neither the quake nor the inundation caused most of the damage and contamination. Rather, it was the aftereffects — specifically, the lack of cooling for the reactor cores and spent fuel, due to a shutdown of outside power — that caused most of the harm.

A new design for nuclear plants built on floating platforms, modeled after those used for offshore oil drilling, could help avoid such consequences in the future. Such floating plants would be designed to be automatically flooded by the surrounding seawater in a worst-case scenario, providing sufficient cooling to indefinitely prevent any melting of fuel rods, or escape of radioactive material.

The concept is being presented this week at the Small Modular Reactors Symposium, hosted by the American Society of Mechanical Engineers, by MIT associate professor of nuclear science and engineering (NSE) Jacopo Buongiorno al...

Smartphone-readable microparticles crack down on counterfeiting

Title: Smartphone-readable microparticles crack down on counterfeiting
Runtime: 3:46
Date posted: 12 years ago
Description: Some 2 to 5 percent of all international trade involves counterfeit goods, according to a 2013 United Nations report. These illicit products — which include electronics, automotive and aircraft parts, pharmaceuticals, and food — can pose safety risks and cost governments and private companies hundreds of billions of dollars annually.

Many strategies have been developed to try to label legitimate products and prevent illegal trade — but these tags are often too easy to fake, are unreliable, or cost too much to implement, according to MIT researchers who have developed a new alternative.

Led by MIT chemical engineering professor Patrick Doyle and Lincoln Laboratory technical staff member Albert Swiston, the researchers have invented a new type of tiny, smartphone-readable particle that they believe could be deployed to help authenticate currency, electronic parts, and luxury goods, among other products. The particles, which are invisible to the naked eye,...

Title: How the brain pays attention
Runtime: 0:09
Date posted: 12 years ago
Description: Picking out a face in the crowd is a complicated task: Your brain has to retrieve the memory of the face you're seeking, then hold it in place while scanning the crowd, paying special attention to finding a match.

A new study by MIT neuroscientists reveals how the brain achieves this type of focused attention on faces or other objects: A part of the prefrontal cortex known as the inferior frontal junction (IFJ) controls visual processing areas that are tuned to recognize a specific category of objects, the researchers report in the April 10 online edition of Science.

Scientists know much less about this type of attention, known as object-based attention, than spatial attention, which involves focusing on what's happening in a particular location. However, the new findings suggest that these two types of attention have similar mechanisms involving related brain regions, says Robert Desimone, the Doris and Don Berkey Professor of Neuroscience, director of MIT's...

Description: Soft robots — which don't just have soft exteriors but are also powered by fluid flowing through flexible channels — have become a sufficiently popular research topic that they now have their own journal, Soft Robotics. In the first issue of that journal, out this month, MIT researchers report the first self-contained autonomous soft robot, a "fish" that can execute an escape maneuver, convulsing its body to change direction, in just 100 milliseconds, or as quickly as a real fish can.

"We're excited about soft robots for a variety of reasons," says Daniela Rus, a professor of computer science and engineering, director of MIT's Computer Science and Artificial Intelligence Laboratory, and one of the researchers who designed and built the fish. "As robots penetrate the physical world and start interacting with people more and more, it's much easier to make robots safe if their bodies are so wonderfully soft that there's no danger if they whack you."

Measuring the migration of river networks

Title: Measuring the migration of river networks
Runtime: 1:48
Date posted: 12 years ago
Description: Large river networks — such as those that funnel into the Colorado and Mississippi rivers — may seem to be permanent features of a landscape. In fact, many rivers define political boundaries that have been in place for centuries.

But scientists have long suspected that river networks are not as static as they may appear, and have gathered geologic and biological evidence that suggest many rivers have been "rewired," shifting and moving across a landscape over millions of years.

Now researchers at MIT and the Swiss Federal Institute of Technology (ETH Zurich) have developed a mapping technique that measures how much a river network is changing, and in what direction it may be moving. Their results are published in this week's issue of Science.

Description: Transparent displays have a variety of potential applications — such as the ability to see navigation or dashboard information while looking through the windshield of a car or plane, or to project video onto a window or a pair of eyeglasses. A number of technologies have been developed for such displays, but all have limitations.

Now, researchers at MIT have come up with a new approach that can have significant advantages over existing systems, at least for certain kinds of applications: a wide viewing angle, simplicity of manufacture, and potentially low cost and scalability.

The innovative system is described in a paper published this week in the journal Nature Communications, co-authored by MIT professors Marin Soljačić and John Joannopoulos, graduate student Chia Wei Hsu, and four others.

Description: Those who study hydrophobic materials — water-shedding surfaces such as those found in nature and created in the laboratory — are familiar with a theoretical limit on the time it takes for a water droplet to bounce away from such a surface. But MIT researchers have now found a way to burst through that perceived barrier, reducing the contact time by at least 40 percent.

Their finding is reported in a paper in the journal Nature co-authored by Kripa Varanasi, the Doherty Associate Professor of Mechanical Engineering at MIT, along with James Bird, a former MIT postdoc who is now an assistant professor of mechanical engineering at Boston University, former MIT postdoc Rajeev Dhiman, and recent MIT PhD recipient Hyukmin Kwon.

Title: Better batteries through biology
Runtime: 1:25
Date posted: 13 years ago
Description: Lithium-air batteries have become a hot research area in recent years: They hold the promise of drastically increasing power per battery weight, which could lead, for example, to electric cars with a much greater driving range. But bringing that promise to reality has faced a number of challenges, including the need to develop better, more durable materials for the batteries' electrodes and improving the number of charging-discharging cycles the batteries can withstand.

Now, MIT researchers have found that adding genetically modified viruses to the production of nanowires — wires that are about the width of a red blood cell, and which can serve as one of a battery's electrodes — could help solve some of these problems.

The new work is described in a paper published in the journal Nature Communications, co-authored by graduate student Dahyun Oh, professors Angela Belcher and Yang Shao-Horn, and three others. The key to their work was to increase the surface...

Title: Self-steering particles
Runtime: 0:43
Date posted: 13 years ago
Description: MIT chemical engineers have designed tiny particles that can "steer" themselves along preprogrammed trajectories and align themselves to flow through the center of a microchannel, making it possible to control the particles' flow through microfluidic devices without applying any external forces.

Such particles could make it more feasible to design lab-on-a-chip devices, which hold potential as portable diagnostic devices for cancer and other diseases. These devices consist of microfluidic channels engraved on tiny chips, but current versions usually require a great deal of extra instrumentation attached to the chip, limiting their portability.

Much of that extra instrumentation is needed to keep the particles flowing single file through the center of the channel, where they can be analyzed. This can be done by applying a magnetic or electric field, or by flowing two streams of liquid along the outer edges of the channel, forcing the particles to stay in the c...

Moon's craters may overstate the intensity of early asteroid impacts

Title: Moon's craters may overstate the intensity of early asteroid impacts
Runtime: 1:29
Date posted: 13 years ago
Description: Scientists have long thought that such lunar craters arose during a period called the Late Heavy Bombardment (LHB), about 4 billion years ago. During that time, a hailstorm of giant asteroids pummeled the solar system, slamming into the moon, along with young planets like Mercury, Venus, Earth, and Mars.

Evidence for this theoretical period comes mostly from the moon itself. While most traces of Earth's early history have been wiped away by erosion and tectonic activity, the moon remains as a nearby, relatively untouched, and easily observable relic of the early solar system. In particular, scientists have based most of their theories of that period on the impact basins found on the moon's near side — the side always facing the Earth — assuming, from the size of its craters and basins, that the moon and other planets endured impacts from massive asteroids.

But now scientists from MIT, the University of Paris, and elsewhere have found that craters on the n...

Title: Solving chromosomes' structure
Runtime: 1:10
Date posted: 13 years ago
Description: Scientists first discovered chromosomes in the late 1800s, after the light microscope was invented. Using these microscopes, biologist Walter Flemming observed many tightly wound, elongated structures in cell nuclei. Later, it was found that chromosomes are made from DNA, the cell's genetic material.

Since then, scientists have proposed many possible ways that DNA molecules might fold into 3-D condensed chromosomes. Now, researchers at MIT and the University of Massachusetts Medical School have obtained novel data on the 3-D organization of condensed human chromosomes and
built the first comprehensive model of such chromosomes.

In this model, DNA forms loops that emanate from a flexible scaffold; the loops are tightly compressed along the scaffold. "This is a very efficient way of packing DNA material," says Leonid Mirny, an associate professor of health sciences and technology and physics at MIT and a senior author of a paper describing the findings ...

Description: Known as M-Blocks, the robots are cubes with no external moving parts. Nonetheless, they're able to climb over and around one another, leap through the air, roll across the ground, and even move while suspended upside down from metallic surfaces.

Inside each M-Block is a flywheel that can reach speeds of 20,000 revolutions per minute; when the flywheel is braked, it imparts its angular momentum to the cube. On each edge of an M-Block, and on every face, are cleverly arranged permanent magnets that allow any two cubes to attach to each other.

Watching tumors burst through a blood vessel

Title: Watching tumors burst through a blood vessel
Runtime: 0:28
Date posted: 13 years ago
Description: Cancer cells metastasize in several stages — first by invading surrounding tissue, then by infiltrating and spreading via the circulatory system. Some circulating cells work their way out of the vascular network, eventually forming a secondary tumor.

While the initial process by which cancer cells enter the bloodstream — called intravasation — is well characterized, how cells escape blood vessels to permeate other tissues and organs is less clear. This process, called extravasation, is a crucial step in cancer metastasis.

Now researchers at MIT have developed a microfluidic device that mimics the flow of cancer cells through a system of blood vessels. Using high-resolution time-lapse imaging, the researchers captured the moments as a cancer cell squeezes its way through a blood vessel wall into the surrounding extracellular matrix. The process is "highly dynamic," as they write in a paper published in the journal Integrative Biology; a better understandi...

Description: MIT researchers have found a new family of materials that provides the best-ever performance in a reaction called oxygen evolution, a key requirement for energy storage and delivery systems such as advanced fuel cells and lithium-air batteries.

The materials, called double perovskites, are a variant of a mineral that exists in abundance in the Earth's crust. Their remarkable ability to promote oxygen evolution in a water-splitting reaction — which breaks water molecules into oxygen and hydrogen — is detailed in a paper appearing in the journal Nature Communications.

This video shows the strong activity of the new catalyst material (dark circle at center) in promoting the oxygen evolution reaction when submerged in water, as revealed by the bubbles of oxygen forming on its surface.

Description: A team of MIT researchers has succeeded in carrying out the first systematic investigation of the factors that control boiling heat transfer from a surface to a liquid. This process is crucial to the efficiency of power plants and the cooling of high-power electronics, and could even lead to improvements in how vehicles travel through water.

The research deals with a key transition point known as the critical heat flux, or CHF, a value of heat transfer, per unit time and area, where a surface's heat-transfer characteristics suddenly change: For example, when the cooling panels of an electronics system become covered with a layer of vapor that blocks heat transfer, the resulting rise in temperature can damage or destroy the equipment. The new findings could raise the value of CHF, providing extra safety margins or operating ranges for such equipment.

Tiny ocean plants use turbulence for travel to social gatherings

Title: Tiny ocean plants use turbulence for travel to social gatherings
Runtime: 0:20
Date posted: 13 years ago
Description: Scientists at MIT and Oxford University have shown that the motility of phytoplankton — which are tiny ocean plants — helps them determine their fate in ocean turbulence. Rather than acting to distribute them evenly — as physics would demand of small particles mixed into a fluid — the individual vortices that make up ocean turbulence are like social mixers for phytoplankton, bringing similar cells into close proximity, potentially enhancing sexual reproduction and other ecologically desirable activities.

In a new paper, William Durham of Oxford, Roman Stocker of MIT and co-authors describe how at the scale of millimeters, phytoplankton caught in a watery vortex form highly concentrated patches at the center of the swirl. In the turbulent ocean where short-lived vortices form continually, this process repeats itself, carrying the microorganisms from social mixer to social mixer.

Description: Social phobias affect about 15 million adults in the United States, according to the National Institute of Mental Health, and surveys show that public speaking is high on the list of such phobias. For some people, these fears of social situations can be especially acute: For example, individuals with Asperger's syndrome often have difficulty making eye contact and reacting appropriately to social cues. But with appropriate training, such difficulties can often be overcome.

Now, new software developed at MIT can be used to help people practice their interpersonal skills until they feel more comfortable with situations such as a job interview or a first date. The software, called MACH (short for My Automated Conversation coacH), uses a computer-generated onscreen face, along with facial, speech, and behavior analysis and synthesis software, to simulate face-to-face conversations. It then provides users with feedback on their interactions.

Title: MIT Hobby Shop
Runtime: 5:33
Date posted: 13 years ago
Description: In the 1937-38 academic year, Vannevar Bush, then Vice President of MIT, granted a group of 16 MIT students permission to use a room in the basement of building 2. With equipment they found around the Institute they set up a wood and metal shop in the 16-foot by 22-foot area. The club members chose the name "Hobby Shop" based on their belief in the philosophy that the well rounded individual pursued interests outside their profession - hobbies.

Now in its 75th year, we take a look back how the Hobby Shop began, and evolved to what it is today.

Nanowires can lift liquids without power

Title: Nanowires can lift liquids without power
Runtime: 1:05
Date posted: 13 years ago
Description: New research carried out at MIT and elsewhere has demonstrated for the first time that when inserted into a pool of liquid, nanowires — wires that are only a few nanometers (billionths of a meter) across — naturally draw the liquid upward in a thin film that coats the surface of the wire. The finding could have applications in microfluidic devices, biomedical research and inkjet printers.

In each video, a single solid nanowire or a network of nanowires are dipped into liquid. Because of capillary action, the liquid is pumped up along the solid nanowire
surface, either as droplets called "Rayleigh beads", or as a thin layer
called a "precursor Film," that is just 5-10 nm thick. At places where
wires intersect, droplets build up, forming reservoirs of liquid. This
level of detail is at least 20 times more powerful than traditional
optical microscope studies of liquid-solid interactions.

MIT visualizes how the brain loses and regains consciousness

Title: MIT visualizes how the brain loses and regains consciousness
Runtime: 0:51
Date posted: 14 years ago
Description: This array of videos shows spectrographic data (representing brain wave frequencies) from each of 44 electrodes attached to the scalp of a healthy volunteer undergoing propofol anesthesia. The spectrograms are arranged according to their approximate position on the scalp, with the front of the head at the top of the screen, and the back of the head at the bottom of the screen. Activity moves from back to front with loss of consciousness (levels 1 to 5) and from back to front with return of consciousness (levels 6 to 8). Each video shows brain activity throughout a 140-minute period of the study. Video by Aylin Cimenser. Reproduced from PNAS with permission.
