“Ultrathin films of a semiconductor that emits and detects light can be stacked on top of silicon wafers. The huge increase in computing performance in recent decades has been achieved by squeezing ever more transistors into a tighter space on …
“Scheme would make new high-capacity data caches 33 to 50 percent more efficient. In a traditional computer, a microprocessor is mounted on a “package,” a small circuit board with a grid of electrical leads on its bottom. The package snaps …
“When freezing droplets impact a surface, they generally either stick to it or bounce away. Controlling this response is crucial to many applications, including 3-D printing, the spraying of some surface coatings, and the prevention of ice formation on structures …
““Air-breathing” battery can store electricity for months, for about a fifth the cost of current technologies. Wind and solar power are increasingly popular sources for renewable energy. But intermittency issues keep them from connecting widely to the U.S. grid …
“Using smartphone cameras, system for seeing around corners could help with self-driving cars and search-and-rescue. Light lets us see the things that surround us, but what if we could also use it to see things hidden around corners? It sounds …
“New research has shown that an exotic kind of magnetic behavior discovered just a few years ago holds great promise as a way of storing data — one that could overcome fundamental limits that might otherwise be signaling the end of …
“Assistant professor of electrical engineering Luqiao Liu is developing new magnetic materials, known as antiferromagnets, that can be operated at room temperature by reversing their electron spin and can serve as the basis for long-lasting, spintronic computer memory. Stephanie Bauman …
“The LIGO Scientific Collaboration and the Virgo collaboration report the first joint detection of gravitational waves with both the LIGO and Virgo detectors. This is the fourth announced detection of a binary black hole system and the first significant gravitational-wave …
“From butterflies that sprout wings to hermit crabs that switch their shells, many animals must adapt their exterior features in order to survive. While humans don’t undergo that kind of metamorphosis, we often try to create functional objects that …
“Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a new system that allows programmers to transplant code from one program into another. The programmer can select the code from one program and an insertion point …
