The article says the materials are capable of acoustic cloaking in air. I assume from that wording that it does not (yet) work in water. But, assuming it could be modified to work underwater (and shielding a ship from sonar means it has to work in water, not in air) perforated plastic plates don't sound [pun intended] all that durable and I imagine they would induce a lot of drag on the hull.
Sure. Obviously we should anticipate and try to prevent all possible threats. So, no more going to a movie, or the mall, or a baseball game without a full-body scan. I think we'll have to scan all vehicles entering parking garages for explosives. And don't even think about bringing that water bottle with you to the theme park, etc. etc. etc. Where does it end?
in the concentration needed of different compounds in order to smell them. Some compounds can be smelled at ppb levels while other take much more. So some "compartments" would make do with just a few mg of a compound while others might need much more. Also, the volatility and diffusivity of different compounds would make it hard to control how much gets delivered to your nose. I suppose one could heat the compartments individually as needed but the first point seems hard to overcome.
Off topic, but the Navy Nuc program has had a zero-tolerance policy on drug abuse. Once, and you're out. I'm pretty sure the SEALs would have a similar policy, being the elite group they are. I was thinking about the joke about the penguin and the ice cream cone....
I see. So, in the UK, Lexus is associated with being a taxi. In the US, that is not the case. Lexus is the luxury (higher end) brand of Toyota and is a common family sedan or SUV. Taxis here are typically domestic sedans (Ford or GM) AFAIK, although I don't have much experience using taxis so I could be wrong.
True, but when one says something is not rare, one usually refers to the existence not being uncommon, not my ability to witness it. Example: jury trials are common occurrences, but I've never seen one myself except as portrayed in movies and TV shows. I would not say jury trials are rare because I haven't seen one.
This. If I counted correctly there were 82 total lunar eclipses in the twentieth century, so nearly one every year on average. Some years actually had two, but there were many gaps greater than one year.

Yes. But this is about bacteria that happens to have the genus name Mycoplasma, not fungi.
Bacterium, not mold. Mycoplasma is genus name of this particular bacterium.
Please mod up. This is the correct interpretation of the headline.
...Brainerd International Raceway.
How about having Jerry Lundegaard do the driving!
Oh, geez. Look, I'm cooperatin' here!
Never mind. I wasn't paying attention. Carry on.
Yes. Next question?

Maybe they're aspiring to a Pulitzer prize.
That was an insult, but it was not an ad hominem. It wasn't part of his argument. It was just there. Unnecessarily.
Small whoosh. Small since it wasn't that funny.
He probably wouldn't hear the whooosh anyway. They are frequently very high frequency, even ultrasonic.
Sticker price is not total-cost-of-ownership. Big difference.
By that reasoning, they should give Rory McIlroy a Grammy. He deserves something but it's in a totally different realm of activity.
I somehow doubt that the people threatening the climate scientists are simply generally opposed to science, either. Things are not so simple.

You lost me with the bit about the young ladies vomiting in the back seat, but overall I like what you wrote.
"Didn't Disney try to trademarn "Seal Team 6"?"
Yes, tried. And failed.
There is still hope.

I'd like to imagine that Enrico Fermi would be dismayed that his homeland has given up on nuclear power.
It gets bored while waiting at red lights?
Automatically updating its drivers? Ba-dum ching!
Yes, we do.
