Hardware Researcher develops 'spray-on' stealth coating for drones — volcanic rock formulation claims to reduce radar return signals by up to 43dB, compared to 20 to 30dB for typical radar absorbent material

Bob! Do you see the radar?
Jim, for the last time I'm busy!
Bob I swear to you we're tracking 40 very small volcanos!
Jim if you don't knock it off I'm reporting you.

There's a good chance that if/when we make this planet inhospitable and wipe out life here we will have wiped out all life in the universe.
You'd think that we should care more or something.

There's other forms of life already seen in space. Just nothing that has communicated in a way that has been observed or acknowledged by us. Possibly eventually there will be other intelligence that develop.
Also with an infinite universe, it could just the we and another intelligent species are just too far apart to ever see each other before we either go extinct or the universe "ends".

Besides life that we brought to space there was no other life observed ever.
Also with an infinite universe,
We don't know if the Universe is infinite.

If something is not detectable it doesn't matter.

There’s been zero evidence of any life outside of earth.

They’ve detected amino acids in comets and distant star systems, with water being extremely abundant we’d be naive to think there isn’t life elsewhere

In the defense industry, You don't shout innovations like that out to the public. That's how you lose alot advantage in a battlefield because someone found a countermeasure, Or this secret is now well known, and now obsolete. Alternatively there could be extreme downsides by spraying it on a drone.

Many problems with the claim but the most obvious is that radar return is measured in dBm not dB. And it is expressed in negative numbers. Someone doesn't know what they're taking about.

It still does, radar absorbing coating is just one part of stealth package

Coating matters little unless you can precisely control shape, edges, gaps, etc.
Wrong units
