Why prescribed fire often fails: Scorched invasive shrubs can resprout instead of die

Researchers led by Dr. Changmin Ahn and Prof. Jungwon Kim at KAIST, in collaboration with Prof. Hansuek Lee, have demonstrated a chip-scale photonic approach for generating ultralow-noise and highly stable microwave and millimeter-wave signals based on optical frequency combs (microcombs), offering a potential pathway toward compact, high-performance frequency sources for next-generation technologies.

I recently lost one of my cocker spaniels, Bobbi. She was fit, healthy and active, but had a catastrophic diagnosis of oral melanoma two months before I had to make the decision that anyone with deeply loved pets dreads.

Two newly published studies by Colleen M. Berryessa, associate professor at the Rutgers University School of Criminal Justice, examine how expressions of remorse are interpreted in the legal system and how those interpretations can contribute to unequal outcomes.

With a small blue crane, four researchers hoist a cylindrical fuel cell, which looks like a stack of flattened silver and gold soda cans bundled together, into the air and lower it into a rectangular cart on wheels. A tangle of tubes and wires spirals away from the system, where nearly 270 sensors and 1,000 components are nestled inside.
