A new study by researchers at the SETI Institute suggests that stellar 'space weather' could make radio signals from extraterrestrial intelligence harder to detect. And the most common M-dwarf stars have the highest likelihood that narrowband signals will be broadened before leaving the system.

I feel like we should be more concerned about having the technological capability to do AT ALL even without ‘space weather’ obscuring it.
We should be looking for neutrino techno-signatures anyway. They’re far more likely to reach us.
Well, I think the bigger thing here is that it means we have been looking for the wrong signatures.
This is an OPPORTUNITY to go back through all the data we have and look for increased power over larger bands. It may also be possible to reconstruct them into narrowband signals as well.
All of this may be especially useful if a “sender” was aware of this phenomenon and adjusted their transmission accordingly.
