I’m from Australia and thought the same thing. This is more ‘pig in duvét’ :)

Agreed. Jet A1 is just clear Kerosene. Avgas has lead but is rarely used and not in commercial flights because it’s so expensive.

Huh, I thought this was already achieved, but perhaps not… https://en.m.wikipedia.org/wiki/Johann_Olav_Koss

The restoration of the habitat is great. I’m a bit concerned that it’s warm enough for dolphins at this time of year.

No, unless they are exposed to the same environment and do not undergo treatment, e.g. if you have a predisposition to cancer resulting from consuming alcohol, your children are unlikely to develop similar cancers if they don’t drink.

Ditto skin cancer, or mutations due to radiation.

It’s about the interactions between the two as they move away and toward each other. Helium will have complete a electron shell and the nucleus is basically at rest. Hydrogen as (H - H) is stable but reactive. Helium is inert.

And the two hydrogens (now a molecule) have more energy because of the intermolecular forces - as the hydrogens oscillate (kind of) their movement towards and away from one another is more energetic than the helium atom just on its own.

Edit: there is a quantum chemistry exercise in calculating the variations in energy between a hydrogen 2+ molecule (two protons sharing an electron) and 3D mapping the changes. It was much more difficult without the internet and digital graphing available nowdays.

That’s the way of NZ. Take no prisoners.
