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

Electrons move through a conducting material like commuters at the height of Manhattan rush hour. The charged particles may jostle and bump against each other, but for the most part they’re unconcerned with other electrons as they hurtle forward, each with their own energy. But when a material’s electrons are trapped together, they can settle […]

New techniques efficiently accelerate sparse tensors for massive AI models

Researchers from MIT and NVIDIA have developed two techniques that accelerate the processing of sparse tensors, a type of data structure that’s used for high-performance computing tasks. The complementary techniques could result in significant improvements to the performance and energy-efficiency of systems like the massive machine-learning models that drive generative artificial intelligence. Tensors are data […]

Accelerating AI tasks while preserving data security

With the proliferation of computationally intensive machine-learning applications, such as chatbots that perform real-time language translation, device manufacturers often incorporate specialized hardware components to rapidly move and process the massive amounts of data these systems demand. Choosing the best design for these components, known as deep neural network accelerators, is challenging because they can have […]

This Pokéball-Sized Sampler Is the Perfect Gift for People Convinced They’re a DJ

Image courtesy of Artiphon Many of the great DJs started by just choppin’ shit up. From DJ Shadow and J Dilla to The Avalanches, a ton of incredible musicians made their breakthroughs by mastering the art of sampling and looping, creating hard-hitting beats and groovy melodies by combining great moments lifted from other places. Since […]

From a five-layer graphene sandwich, a rare electronic state emerges

Ordinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a human hair. Under a microscope, the material resembles a chicken-wire of carbon atoms linked in a hexagonal lattice. Despite its […]

Finger-shaped sensor enables more dexterous robots

Imagine grasping a heavy object, like a pipe wrench, with one hand. You would likely grab the wrench using your entire fingers, not just your fingertips. Sensory receptors in your skin, which run along the entire length of each finger, would send information to your brain about the tool you are grasping. In a robotic […]

Internships fabricate a microelectronics future

Nestled among the diverse labs and prototyping facilities at MIT Lincoln Laboratory, the Microelectronics Laboratory (ML) whirs away. Technicians in the ML fabricate advanced integrated circuits, which end up in systems that peer into the cosmos, observe weather from space, and power quantum computers — to name just a few uses. The ML is one […]

System combines light and electrons to unlock faster, greener computing

Computing is at an inflection point. Moore’s Law, which predicts that the number of transistors on an electronic chip will double each year, is slowing down due to the physical limits of fitting more transistors on affordable microchips. These increases in computer power are slowing down as the demand grows for high-performance computers that can […]

Smart pill can track key biological markers in real-time

Researchers from MIT, Boston University, and elsewhere report a smart pill the size of a blueberry that could be a game changer in the diagnosis and treatment of bowel diseases. That’s because it is the first technology compatible with ingestion that can automatically detect — and report on in real time — key biological molecules […]

Device offers long-distance, low-power underwater communication

MIT researchers have demonstrated the first system for ultra-low-power underwater networking and communication, which can transmit signals across kilometer-scale distances. This technique, which the researchers began developing several years ago, uses about one-millionth the power that existing underwater communication methods use. By expanding their battery-free system’s communication range, the researchers have made the technology more […]

Laser-based system achieves noncontact medical ultrasound imaging

Researchers from MIT Lincoln Laboratory and their collaborators at the Massachusetts General Hospital (MGH) Center for Ultrasound Research and Translation (CURT) have developed a new medical imaging device: the Noncontact Laser Ultrasound (NCLUS). This laser-based ultrasound system provides images of interior body features such as organs, fat, muscle, tendons, and blood vessels. The system also measures […]

Teaching students about photonics to build up the US workforce

In 2019, Kevin McComber ’05, PhD ’11 was at MIT working on integrated photonics — chip-based devices that send and receive signals using light — and set out to hire someone to design photonic chips. The experience made him realize just how little expertise the U.S. workforce has in integrated photonics design, a problem that’s […]
