Molecular magnetism packs power with “messenger electron”

Electrons can be a persuasive bunch, or at least, a talkative bunch, according to new work from John Berry’s lab at the University of Wisconsin–Madison. The spins of unpaired electrons…

Researchers develop flexible, stretchable photonic devices

CAMBRIDGE, Mass. — Researchers at MIT and several other institutions have developed a method for making photonic devices — similar to electronic devices but based on light rather than electricity…

Unlocking the potential of magnetic skyrmions

An innovative technique for making tunable magnetic skyrmions could lead to next-generation memory and computing technologies. Magnetic skyrmions offer the promise of next-generation memory and computing technologies, such as cache…

Faster big-data analysis

System for performing “tensor algebra” offers 100-fold speedups over previous software packages. CAMBRIDGE, Mass. — We live in the age of big data, but most of that data is “sparse.” Imagine,…

Selective memory

Scheme would make new high-capacity data caches 33 to 50 percent more efficient. CAMBRIDGE, Mass. — In a traditional computer, a microprocessor is mounted on a “package,” a small circuit…

Researchers bring optical communication onto silicon chips

Ultrathin films of a semiconductor that emits and detects light can be stacked on top of silicon wafers. CAMBRIDGE, Mass. — The huge increase in computing performance in recent decades…

Automatic code reuse

System makes modifications necessary to transplant code from one program into another. CAMBRIDGE, Mass. — Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a new system that…

How neural networks think

General-purpose technique sheds light on inner workings of neural nets trained to process language. CAMBRIDGE, Mass. — Artificial-intelligence research has been transformed by machine-learning systems called neural networks, which learn how…

Making data centers more energy efficient

Flash-memory system could reduce power consumption of data center “caches” by 90 percent. CAMBRIDGE, Mass. — Most modern websites store data in databases, and since database queries are relatively slow, most…

Automatic image retouching on your phone

System can apply a range of styles in real-time, so that the viewfinder displays the enhanced image. CAMBRIDGE, Mass. — The data captured by today’s digital cameras is often treated as…
