Irritation causes inflammation. It might appear to be a disease if you can't figure out what is causing the irritation.

Sure, that's what science "knows" about it so far, but the idea that gut bacteria are a deciding factor also fits perfectly along with your "genetic or environmental" concept. If all you have is a hammer (genetics, environmental observation) then everything looks like a nail. Maybe there's more to it than bacteria, but the chemicals that we put into our body very obviously can affect behaviour and mental state.

Yep, but the one that helps disrupted the already established bacteria, probably by reducing their supply chain. The fact that this chemical was elevated 48 time above normal levels in the autistic mice suggests that it's produced by the "bad" bacteria somehow.

Probably quite a lot through the course of the day, though I suppose a lot of them might die in that environment. I guess I should have said "gut", then. When I say "stomach" I'm often referring to the whole intestinal area, the same as someone might say "lie on your stomach", when in fact they mean your belly..

Is it not the case that the metabolite is necessary for the problem bacteria to replicate - but that the healthy mice don't have these bacteria in the first place, so introducing it won't have the same effect?

Did you consider that it might not be passed on through DNA at all, and completely is a result of the environment, including the bacteria that your mum's side of the family have in their body? Or perhaps your DNA makes you more susceptible to these bacteria. I've been trying to figure out how exactly food affects my mood and behaviour for a while now..

The thing is that if it's gut microbes, then good food will cause problems too. It will depend exactly what the bacteria's preferred food source is though. And toxins from bacteria in your stomach can absolutely affect your mood and ability to function.

Good point :p I was just thinking of my friends who are always concerned about a few pennies difference on groceries, but I guess they can't afford a new car in the first place. And electric cars aren't going to be great in the used market until battery tech/cost improves.

Considering the price of energy and the whole economic crisis, a lot of people would probably rather plug in manually if the losses are any more than a couple of percent. Even 1% would probably put a lot of people off if they were aware of it.

There's a reason that there's "American English" and "English".. I'm not sure why you have to make it about "winning". That's one of the major flaws when it comes to humanity in general, not being able to realise how life doesn't always need to be about "us vs them". Or "US vs them". Ho ho ho..

From the definitions I can find, a barge is always a boat, whether it's powered or not.

And from Wikipedia, this looks like another case of the US having a different perception of things from the rest of the world, because it sounds like all your barges are basically just trailers for tugboats.

Barges have to be flat bottomed, though I'm guessing this thing may be flat bottomed. Barges can also have their own propulsion, for example the river homes that people pilot around the canals here in the UK are barges.

Oh gee, I guess you figured out a problem in their plan - I can't believe they didn't notice that!

Either that or you're not part of their intended market.

I don't know why mechanical failure is any more of a "real" accident than software failure? If the drone is properly designed and maintained, then an accident due to mechanical failure should be less common than mechanical failure in properly maintained aircraft. The design of quad/hex/whatever drones is simpler and has more redundancy than any aircraft designed to carry people. The only accidents outside of human control would be things like bird strikes.

You mean actions like embarrassing funny coloured people at an airport, or invading their country?
