Chip-scale photonic approach achieves ultralow-noise microwave and millimeter-wave signal generation

Invasive woody plants present a major ecological challenge in eastern U.S. forests by outcompeting native species and spreading quickly, forming dense thickets that crowd out native plants and disrupt ecosystems. Land managers have tried, with some success, to use prescribed fire to kill them, but is it effective? Researchers at Penn State reported mixed results when it comes to two of the most aggressive colonizers across North American landscapes: burning bush and border privet.

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.
