AI Tool for COVID Monitoring Offers Solution for Urban Congestion
Researchers at NYU have developed an AI solution that can leverage public video feeds to better inform decision makers → Read More
Live Bacteria Bang Out Solos on Graphene Drum
Graphene is basically all surface. This makes graphene highly sensitive to atoms or molecules because its entire volume serves as a sensor surface. This has led researchers and industry to exploit graphene as both a biosensor and an electronic sensor. Now Dutch scientists.... → Read More
IBM’s New Telum Chip Reboots the Mainframe
The mainframe’s diminishing significance today does not mean it’s dwindling away either. IBM has touted their z16 mainframe’s real-time AI processing of transactions for fraud and lauded it as “industry’s first quantum-safe system.” But at the core of all this is Big Blue’s Telum chip. → Read More
AI Blazes Path Toward Dissipationless Electronics
A new AI algorithm has been developed that offers to drastically trim back the time needed to iterate designs of a promising new material called the topological insulator. “It has reduced the analysis from days to minutes without exaggeration,” said Mingda Li, professor at MIT. → Read More
Printing Circuits on Nanomagnets Yields a New Breed of AI
Researchers at Los Alamos National Laboratory have for the first time made an artificial spin glass consisting of nanomagnets arranged in a way that mimics a neural network. Spin glass models have previously been used to model complex systems, including brain function and stock market dynamics. → Read More
Exotic, 2D Materials Could Resurrect the Hard Drive
“Multiferroics” offer both the higher data fidelity of hard drives with flash memory's reliance on only electric fields (eliminating the clumsy and bulky HDD magnetic head) to read and write. → Read More

Water Scarcity Concerns Drive Semiconductor Industry to Adopt New Technologies
In these days of seemingly neverending chip shortages, more and greater varieties of semiconductors are in demand. Chip fabs around the world are now racing to catch up to the world's many microelectronic needs. And chip fabs need a lot of water to operate. Too much, they're realizing → Read More
Insulator-Conductor Transition Points Toward Ultra-Efficient Computing
Looking to such specialized nervous systems as a model for artificial intelligence may prove just as valuable, if not more so, than studying the human brain. Consider the brains of those ants in your pantry. Each has some 250,000 neurons. Larger insects have closer to 1 million. In my research at Sandia National Laboratories in Albuquerque, I study the brains of one of these larger insects, the… → Read More
IBM Makes Tape Storage Better Than Ever
IBM just shattered previous records for magnetic tape’s data storage capabilities, ensuring it meets demand for the next decade → Read More
Is Graphene by Any Other Name Still Graphene?
Consumers may finally have a way to know if their graphene-enabled products actually get any benefit from the wonder material → Read More
How the Potential Tech Worker Exodus from Britain Benefits Ireland
The confusion around the United Kingdom's future is already a factor in recruitment → Read More
Europe Has Invested €1 Billion Into Graphene—But For What?
Six years into an ambitious 10-year research project, experts weigh in on whether the Graphene Flagship can help the “wonder material” make it through the Valley of Death → Read More
