Interesting, but it seems the author is a bit confused.
Now, things get really exciting. Nitrogen nuclei with 14 neutrons are stable. But take one of those neutrons away, and you're left with nitrogen-13, an unstable, radioactive isotope. Similarly, oxygen-16 is stable, but -15 … not so much.
Like many other "science facts", I question the existence of "anti-matter". Opposite charge I can understand, anti-matter, not so much. Seems too much like a "quantum black hole" fantasy.
It's long been known that lightning on the earth and in the earth's atmosphere produces gamma radiation. It's good to see "mainstream scientists" peeking out from under the deadening blanket of Newtonian physics and Einstein's relativistic theories to actually see the light of the universe. I'm still quite puzzled as to how France can turn out some brilliant scientists but can't produce a firearm worth shooting but, that's another topic for another day. Chinese scientists are blazing some serious trails in discovering the electrical energies of the universe AND how to start harnessing this knowledge for it's utility and service to humanity.
Yeah, the guy who wrote the article for Live Science is still digging around for the conventional (read: failed) explanations of Newtonian physics and relativistic theories which is why he stumbles on the nuclear similes. Sort of like using cow's milk to explain modern industrial coatings...the disconnect is becoming quite obvious.
Antimatter is known to exist. Dark matter is not. Dark matter is what they say adds the mass that would seem to be necessary for the Universe to behave as we observe it to behave.
....but it could also be that we just don't fully understand everything we see in the Universe. Which is the reason we have science. It's the quest to figure it all out.
Science: the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.
If we knew all the answers, experiments based on our observations wouldn't be necessary.
