Robots swim with the fishes : New robots mimic fish's swimming, could be used in underwater exploration

Location: Cambridge, United States

Borrowing from Mother Nature, a team of MIT researchers has built a school of swimming robo-fish that slip through the water just as gracefully as the real thing, if not quite as fast.

Mechanical engineers Kamal Youcef-Toumi and Pablo...

Pushing the envelope of general relativity

Location: Tokyo, Japan

Einstein introduced general relativity in the early 20th century, and since then it has been proven to be an accurate description of gravity beyond the regime of validity of Newtonian gravitation. Since then, people have been asking...

Confinement of Electrons to Diamond Isotopes : Super lattice structure realized using only carbon

Location: Tsukuba, Japan

Among all available materials, diamond has the optimal characteristics with respect to hardness, thermal conductivity, light transmission wavelength range, and chemical stability. Furthermore, as a semiconducting material, diamond shows...

A better way to pinpoint underground oil reserves : CEE mapping technology could make extraction more efficient

Location: Cambridge, United States

An accurate map of a large underground oil reservoir that can guide engineers' efforts to coax the oil from the vast rocky subsurface into wells where it can be pumped out for storage or transport.

Researchers in MIT's Department of...

Robo-forklift keeps humans out of harm's way : Could allow military to handle supplies without risk to people

Location: Cambridge, United States

Researchers in MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) are working on a better way to handle supplies in a war zone: a semi-autonomous forklift that can be directed by people safely away from the dangers of the...

Physicists discover surprising variation in superconductors : Work may lead to understanding of new class of materials

Location: Cambridge, United States

MIT physicists have discovered that several high-temperature superconductors display patchwork quilt-like variations at the atomic scale, a surprising finding that could help scientists understand a new class of unconventional materials....

Electrically Measuring Method for a Quantum State of a Semiconductor Artificial Molecule : Applications in quantum information processing are expected

Location: Tsukuba, Japan

Background and history of research:

As electronic commerce increases in popularity and information security management at work and at home becomes more critical, there is a growing need to improve encryption technology for open...

Enlisting microbes to solve global problems : Researchers harness bacteria to produce energy, clean up environment

Location: Cambridge, United States

In the search for answers to the planet's biggest challenges, some MIT researchers are turning to its tiniest organisms: bacteria.

The idea of exploiting microbial products is not new: Humans have long enlisted bacteria and yeast to...

Stuck in the middle : research explains how thin layers of tiny organisms form at sea; work could help predict harmful algal blooms like red tide

Location: Cambridge, United States

Not far beneath the ocean's surface, tiny phytoplankton swimming upward in a daily commute toward morning light sometimes encounter the watery equivalent of Rod Serling's Twilight Zone: a sharp variation in marine currents that traps...

More power from bumps in the road : energy-harvesting shock absorbers

Location: Cambridge, United States

A team of MIT undergraduate students has invented a shock absorber that harnesses energy from small bumps in the road, generating electricity while it smoothes the ride more effectively than conventional shocks. The students hope to...

Researchers make carbon nanotubes without metal catalyst : Oxides, as well as metals, seem to be able to sprout carbon nanotubes, study finds

Location: Cambridge, United States

Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. A major problem, however, is that the metals used to grow...

New rocket aims for cheaper nudges in space : Plasma thruster is small, runs on inexpensive gases

Location: Cambridge, United States

Satellites orbiting the Earth must occasionally be nudged to stay on the correct path. MIT scientists are developing a new rocket that could make this and other spacecraft maneuvers much less costly, a consideration of growing importance as...

The effect of dissolved hydrogen on spent nuclear fuel corrosion

Location: Chalmer, Sweden

Abstract :

In case of a canister failure in a deep bedrock repository for nuclear fuel, the release of radiotoxic nuclides to the groundwater will depend on the chemical environment near the fuel surface. Due to the presence of large...

Good vibrations : Devices aid the deaf by translating sound waves to vibrations

Location: Cambridge, United States

Lip reading is a critical means of communication for many deaf people, but it has a drawback: Certain consonants (for example, p and b) can be nearly impossible to distinguish by sight alone.

Tactile devices, which translate sound...

Knowing when to fold : Engineers use 'nano-origami' to build tiny electronic devices

Location: Cambridge, United States

Folding paper into shapes such as a crane or a butterfly is challenging enough for most people. Now imagine trying to fold something that's about a hundred times thinner than a human hair and then putting it to use as an electronic device....

Oxide-based SOFC Anode Materials

Location: WA, United States

In a fuel cell, the anode facilitates the reaction between hydrogen, carbon monoxide and hydrocarbon fuels with oxygen ions that permeate the electrolyte from the cathode side of the cell. An ideal anode should have high electrical...

'Nanostitching' could lead to much stronger airplane skins, more

Location: Cambridge, United States

MIT engineers are using carbon nanotubes only billionths of a meter thick to stitch together aerospace materials in work that could make airplane skins and other products some 10 times stronger at a nominal increase in cost.

Moreover,...

Re-engineered battery material could lead to rapid recharging of many devices : Beltway for electrical energy solves long-standing problem

Location: Cambridge, United States

MIT engineers have created a kind of beltway that allows for the rapid transit of electrical energy through a well-known battery material, an advance that could usher in smaller, lighter batteries -- for cell phones and other devices -- that...

Optimal Estimation of the Surface Fluxes of Chloromethanes Using a 3-D Global Atmospheric Chemical Transport Model

Location: Cambridge, United States

The four chloromethanes - methyl chloride (CH3Cl), dichloromethane (CH2Cl2), chloroform (CHCl3), and carbon tetrachloride (CCl4), are chlorine-containing gases contributing significantly to stratospheric ozone depletion and having adverse...

New greenhouse gas identified:Early detection may permit 'nipping it in the bud'

Location: Cambridge, United States

A gas used for fumigation has the potential to contribute significantly to future greenhouse warming, but because its production has not yet reached high levels there is still time to nip this potential contributor in the bud, according to...
