Usually HN filters out repeats, but not this time. Very strange and interesting.

Yup, but on a different site; it's a press release. I find funny that in my submission people were complaining that I removed the 'may' part of the title; in this one, people are complaining of the opposite ;)

Is anyone else bothered by the use of "confirm" and "may" in the same sentence? If it's confirmed, it is, not may be, right?

Personally, yes. But this is standard scientific nomenclature.

Not at all.

If I am trying to reverse engineer a bread recipe, and find CO2, I will have confirmed yeast may have been used.

It's logically equivalent to "Scientists confirmed yeast could not be ruled out." That happens all the time. There is absolutely nothing to be bothered by. Running an experiment and getting a maybe is important and valid scientific information.

We are aliens?
