  • Microfluidics Could Be the Answer to Cooling AI Chips November 17, 2025
    Data center rack density has risen rapidly in recent years. Operators are cramming more computing power into each server rack to meet the needs of AI and other high-performance computing applications. That means that each rack needs more kilowatts of energy, and ultimately generates more heat. Cooling infrastructure has struggled to keep pace.“Rack densities have […]

  • Your Laptop Isn’t Ready for LLMs. That’s About to Change November 17, 2025
    Odds are the PC in your office today isn’t ready to run AI large language models (LLMs).Today, most users interact with LLMs via an online, browser-based interface. The more technically inclined might use an application programming interface or command line interface. In either case, the queries are sent to a data center, where the model […]

  • Apple’s Failed Foray Into Mac Clones November 14, 2025
    There’s a class of consumer that wants something they know they cannot have. For some of those people, a Macintosh computer not made by Apple has long been a desired goal.For most of the Mac’s history, you could only really get one from Apple, if you wanted to go completely by the book. Sure, there […]

  • Could Terahertz Radar in Cars Save Lives? November 20, 2025
    A few years ago, Matthew Carey lost a friend in a freak car accident, after the friend’s car struck some small debris on a highway. The accident happened under conditions that render nearly all of today’s car-mounted sensors useless: fog and bright early-morning sunshine. Radar can’t see small objects well, lidar is limited by fog, […]

  • Quantum Sensor Startup Seeks Flaws in 3D Chips November 18, 2025
    Chipmakers are increasingly stacking transistor-packed layers on top of each other to cram even more computing power into any given space. However, today’s technologies for spotting buried defects that can ruin these 3-D chips are either inadequate or downright destructive. But, new quantum sensors based on artificial diamonds might help foundries quickly catch these hidden […]

  • DARPA and Texas Bet $1.4 Billion on a Unique Foundry November 10, 2025
    A 1980s-era semiconductor fab in Austin, Texas, is getting a makeover. The Texas Institute for Electronics (TIE), as it’s called now, is tooling up to become the only advanced packaging plant in the world that is dedicated to 3D heterogeneous integration (3DHI)—the stacking of chips made of multiple materials, both silicon and non-silicon. The fab […]

  • Startup Using Nanotips and Naphthalene for New Satellite Thruster November 9, 2025
    It sounds like a NASA pipe dream: a new spacecraft thruster that’s up to 40 percent more power-efficient than today’s. Even better, its fuel costs less than a thousandth as much and weighs an eighth of the mass. A startup called Orbital Arc claims it can make such a thruster.With this design, “we can go […]

  • Chips Need to Chill Out November 1, 2025
    Diamonds, lasers, and oil aren’t the first things you may think of when considering ways to keep chips and computers cool. But as modern chip designs pack and stack more transistors into ever smaller spaces, heat has emerged as a critical problem.To solve it, the semiconductor industry is throwing everything at the wall. What sticks […]
