Ace Frehley, may he rest in rock, was my favorite guitarist. A nice article, but c'mon (and love me) - "I Was Made for Loving You" was not "sparking a metal fever" in its prime. It's disco. www.nbcnews.com/news/us-news...

Ace Frehley, legendary Kiss guitarist, dies at 74
The cause of death wasn't immediately released. Frehley fell in his studio in September and had recently canceled his 2025 tour dates.

Neither organic carbon nor phosphorous are pollutants without the proper context. Ecosystems need both, and at least from the organic carbon perspective the type of the carbon matters. Different types of organic carbon react differently in natural waters. Phosphorus is an essential nutrient! 1/

Federal research funding isn’t just for the benefit of scientists. A key part of many NSF grants requires researchers to share their findings with the public, including K-12 students. This “broader impacts” component helps make science more accessible while benefiting society🧪

Basic research advances science, and can also have broader impacts on modern society
Basic research that doesn’t have a specific industrial or experimental application still adds value outside the lab by engaging people with exciting research.
