Harmful killer electrons in space now accurately predictable.

Phys.org: New model accurately predicts harmful space weather.
A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt.

...the model can accurately give a one-day warning prior to a space storm of ultra-high-speed electrons, often referred to as "killer" electrons because of the damage they can do to spacecraft such as navigation, communications, and weather monitoring satellites.

"...being able to accurately predict space weather has been a goal for a long time. This model is a firm step towards being able to do that," [said Yue Chen, a space scientist at Los Alamos National Laboratory and lead author of the study].

"The more research and refinements we do, the increased potential for us to have more reliable forecasts with longer warning time before the arrival of new killer electrons," [said Chen].

Democrats in the U.S. Senate and House quickly condemned the Los Alamos study calling the identification and profiling of "killer electrons" as killer-electron-phophia and declaring it a humanitarian crisis.

Killer electrons...still not as scary as these guys.
