New power sources

“Thirty-six million people in the U.S. use an energy system developed by a handful of activists in the 1990s. An MIT scholar examines this unusual story. In the mid-1990s, a few energy activists in Massachusetts had a vision: What …

Physicists observe an exotic “multiferroic” state in an atomically thin material

“Discovery shows for the first time that multiferroic properties can exist in a two-dimensional material; could lead to more efficient magnetic memory devices. MIT physicists have discovered an exotic “multiferroic” state in a material that is as thin as a …

Robotic cubes shapeshift in outer space

“Self-reconfiguring ElectroVoxels use embedded electromagnets to test applications for space exploration. If faced with the choice of sending a swarm of full-sized, distinct robots to space, or a large crew of smaller robotic modules, you might want to enlist the …

A new upper limit on the mass of neutrinos

“Researchers with the KATRIN experiment determine that neutrinos are lighter than 0.8 eV/c2. In a milestone that will bear on future discoveries in nuclear and particle physics, today an international team including scientists from MIT announced that they …

Light could boost performance of fuel cells, lithium batteries, and other devices

“With many devices depending on the motion of ions, light could be used as a switch to turn ion motion on and off. Engineers from MIT and Kyushu University in Japan have demonstrated for the first time how light can …

New plant-derived composite is tough as bone and hard as aluminum

“The material could pave the way for sustainable plastics. The strongest part of a tree lies not in its trunk or its sprawling roots, but in the walls of its microscopic cells. A single wood cell wall is constructed from …

Scientists discover a mysterious transition in an electronic crystal

“Thermal span in a layered compound promises applications in next-generation electrical switches and nonvolatile memory. When temperature changes, many materials undergo a phase transition, such as liquid water to ice, or a metal to a superconductor. Sometimes, a so-called hysteresis …

Invisible machine-readable labels that identify and track objects

“If you download music online, you can get accompanying information embedded into the digital file that might tell you the name of the song, its genre, the featured artists on a given track, the composer, and the producer. Similarly, if …

New lightweight material is stronger than steel

“The new substance is the result of a feat thought to be impossible: polymerizing a material in two dimensions. Using a novel polymerization process, MIT chemical engineers have created a new material that is stronger than steel and as light …

Physicists manipulate magnetism with light

“Work has potential applications in memory storage and demonstrates a rare form of matter With the help of a “playground” they created for observing exotic physics, MIT scientists and colleagues have not only found a new way to manipulate magnetism …
