Researchers discover new channels to excite magnetic waves with terahertz light

“The finding provides new insights into the ultrafast control of magnetic materials, with potential to enable next-generation information processing technologies. Plucking a guitar string is a simple action that generates a harmonic series of overtones. However, skilled guitar players can …

Researchers harness 2D magnetic materials for energy-efficient computing

“An MIT team precisely controlled an ultrathin magnet at room temperature, which could enable faster, more efficient processors and computer memories. Experimental computer memories and processors built from magnetic materials use far less energy than traditional silicon-based devices. Two-dimensional magnetic …

This tiny, tamper-proof ID tag can authenticate almost anything

“MIT engineers developed a tag that can reveal with near-perfect accuracy whether an item is real or fake. The key is in the glue on the back of the tag. A few years ago, MIT researchers invented a cryptographic ID …

Accelerating AI tasks while preserving data security

“The SecureLoop search tool efficiently identifies secure designs for hardware that can boost the performance of complex AI tasks, while requiring less energy. With the proliferation of computationally intensive machine-learning applications, such as chatbots that perform real-time language translation, device …

Engineers develop an efficient process to make fuel from carbon dioxide

“The approach directly converts the greenhouse gas into formate, a solid fuel that can be stored indefinitely and could be used to heat homes or power industries. The search is on worldwide to find ways to extract carbon dioxide from …

New laser setup probes metamaterial structures with ultrafast pulses

“The LIRAS technique could speed up the development of acoustic lenses, impact-resistant films, and other futuristic materials. Metamaterials are products of engineering wizardry. They are made from everyday polymers, ceramics, and metals. And when constructed precisely at the microscale, in …

Physicists trap electrons in a 3D crystal for the first time

“The results open the door to exploring superconductivity and other exotic electronic states in three-dimensional materials. Electrons move through a conducting material like commuters at the height of Manhattan rush hour. The charged particles may jostle and bump against each …

Team engineers nanoparticles using ion irradiation to advance clean energy and fuel conversion

“The work demonstrates control over key properties leading to better performance. MIT researchers and colleagues have demonstrated a way to precisely control the size, composition, and other properties of nanoparticles key to the reactions involved in a variety of clean …

This 3D printer can watch itself fabricate objects

“Computer vision enables contact-free 3D printing, letting engineers print with high-performance materials they couldn’t use before. With 3D inkjet printing systems, engineers can fabricate hybrid structures that have soft and rigid components, like robotic grippers that are strong enough …

With a quantum “squeeze,” clocks could keep even more precise time, MIT researchers propose

“More stable clocks could measure quantum phenomena, including the presence of dark matter. The practice of keeping time hinges on stable oscillations. In a grandfather clock, the length of a second is marked by a single swing of the pendulum …
