Most dark matter labs are deep underground, minimizing background signals from cosmic radiation. (discovermagazine.com)
To provide records for the global background signal of greenhouse gases and climate change, we will investigate areas largely unaffected by methane and use them as control areas. (cage.uit.no)
After painstakingly removing multiple sources of background signals, the team was left with a neutrino flux of 66 billion per square centimeter per second, close to the standard solar model prediction of 60 billion, they report online today in Nature. (sciencemag.org)
