europe cooling air conditioner

Europe is testing air conditioners that don't use any refrigerants at all

Solid-state cooling startups test semiconductor, magnetic, and pressure-based heat pumps across Europe
The big picture: A new generation of cooling technology is beginning to move from lab testing into early real-world trials, as researchers and startups look for ways to cool buildings without relying on traditional refrigerants. The push comes as demand for air conditioning accelerates in Europe, where rising temperatures are exposing the limits of both existing systems and the buildings they are meant to cool.

Researchers are turning old Pixel phones into a data center – and they outperform some server hardware

Old smartphones are piling up as e-waste, but wait... 25 phones can match a single server CPU
Forward-looking: Researchers at the University of California San Diego are testing whether retired smartphones can still do useful work instead of ending up as electronic waste. Working with Google, the team is trying to turn retired Pixel smartphones into a low-cost data center. The goal is to keep working hardware in use instead of throwing it out after a few upgrade cycles.

Moore's law is hitting a wall, so researchers are stacking silicon chip layers instead of shrinking them

University of Illinois team stacks three active silicon layers on a single chip, achieving 98-100% transistor yield
Forward-looking: For years, the chip industry has chased better performance by shrinking transistors and squeezing more of them onto a flat slice of silicon. That strategy is running into hard limits. A group at the University of Illinois thinks the next gains will come not from going smaller, but from going vertical.
ultra-fast internet japan research fiber optics speed record

Researchers hit 112Gbps over wireless in a breakthrough that could shape 6G

100Gbps-class wireless communication could be the next big thing
Looking ahead: Researchers at Japan's Tokushima University, the University of Tokyo, and Gifu University have developed a terahertz wireless communication system capable of transmitting data at 112Gbps in the 560GHz band. This is significantly faster than the few-gigabit-per-second data rates typically achieved by conventional terahertz communication systems operating at similar frequencies.
