Does anyone know why such a fundamental gene would have such different behaviours between mammals?
> In previous mouse studies, loss of NANOG disrupted both the epiblast and the yolk sac - a tissue that supports the developing embryo. In this human embryo study, loss of NANOG primarily affected the epiblast, the future body-forming line of cells.
It is a bit strange why EU countries allow their own credibility and legitimacy get steadily dragged down, bit by bit, by all these thousands of dubious statements, tricks, manoeuvres, and so on.
Do they just not care about weakening their own societies?
Even if food quality remained exactly the same… By definition Americans would still be on average slightly less healthy, and so on… since the population grew so much? (and grew older)
There’s no magical low effort way to avoid regression to the global mean, as the population more than doubles in size.
That takes serious, coordinated, and sustained work across decades to avoid.
Modern high bypass jet engines are already pretty close to maximum possible thermodynamic efficiency, given realistic constraints such as weight, wing clearance, noise, and so on.
Even if all constraints were relaxed, the absolute limit might be another halving of fuel consumption. (with trillions of R&D)
And beyond that, there literally can never be jet engines significantly more efficient, until the end of the universe.
