But ecologists don't agree whether it's better to focus on preserving many smaller, fragmented tracts of land or larger, continuous landscapes. The study, published in Nature and led by U-M ecologist Thiago Gonçalves-Souza, comes to a conclusion on the decades-long debate.
"Fragmentation is bad," said study author Nate Sanders, U-M professor of ecology and evolutionary biology. ...
Ultra-broadband photonic chip boosts optical signals
2025-03-12
Modern communication networks rely on optical signals to transfer vast amounts of data. But just like a weak radio signal, these optical signals need to be amplified to travel long distances without losing information. The most common amplifiers, erbium-doped fiber amplifiers (EDFAs), have served this purpose for decades, enabling longer transmission distances without the need for frequent signal regeneration. However, they operate within a limited spectral bandwidth, restricting the expansion of optical networks.
To meet the growing demand for high-speed data transmission, researchers have been seeking ways to develop more powerful, flexible, ...
