A more than $40 million investment to add advanced nano-fabrication equipment and capabilities to MIT.nano will significantly expand the center’s nanofabrication capabilities, reports Jon Chesto for The Boston Globe. The new equipment, which will also be available to scientists outside MIT, will allow “startups and students access to wafer-making equipment used by larger companies. These tools will allow its researchers to make prototypes of an array of microelectronic devices.”

Neil Thompson, director of the FutureTech research project at MIT CSAIL and a principal investigator MIT’s Initiative on the Digital Economy, speaks with Politico reporter Mohar Chatterjee about generative AI, the pace of computer progress and the need for the U.S. to invest more in developing the future of computing. “We need to make sure we have good secure factories that can produce cutting-edge semiconductors,” says Thompson. “The CHIPS Act covers that. And people are starting to invest in some of these post-CMOS technologies — but it just needs to be much more. These are incredibly important technologies.”

Popular Science reporter Andrew Paul writes that MIT engineers have developed a new chip for smart phones that blocks unwanted signals, which could “greatly reduce production costs, make devices smaller and more efficient, and potentially even improve battery life.” Graduate student Soroush Araei explains that “our research can make your devices work better with fewer dropped calls or poor connections caused by interference from other devices.”

Researchers from MIT have discovered a hardware vulnerability in Apple’s M1 chip using an attack called PACMAN, reports Harry Guinness for Popular Science. “Attackers can only use PACMAN to exploit an existing memory bug in the system, which can be patched,” explained Guinness.

CSAIL researchers have found a security vulnerability in Apple’s M1 chip, reports Philip Tracy for Gizmodo. “The flaw could theoretically give bad actors a door to gain full access to the core operating system kernel,” explains Tracy.

MIT researchers have discovered a hardware vulnerability in Apple’s M1 chips that can allow attackers to break through its security defenses, reports Carly Page for TechCrunch. “Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory, however, have created a novel hardware attack, which combines memory corruption and speculative execution attacks to sidestep the security feature,” writes Page.

In an article for Fast Company, Charles Fishman explores how MIT researchers pioneered the use of integrated circuits, technology that is an integral component of today’s digital technologies, in the Apollo 11 computer. “MIT, NASA, and the race to the Moon laid the very foundation of the digital revolution, of the world we all live in,” writes Fishman.

MIT researchers are developing a new computer chip to increase efficiency and decrease the carbon footprint of cloud computing, reports Daniela Hernandez for The Huffington Post. Hernandez explains that the chip “uses light, instead of electricity, as the highway for information.”

Neel V. Patel interviews Professor Srini Devadas for Popular Science about the future of computer chip design. Devadas contends that there is still room for innovation of chips using existing materials.

R. Colin Johnson of EE Times reports that MIT researchers are, “aiming for a multicore architecture that can scale to any number of cores, with cache coherency. So far, they've prototyped a 36-core version.”
