Scientifically speaking, how were the wooden doors used in the Nazi gas chambers kept airtight

I think it s because you can simultaneosly train the same muscle with shitting big turds and giving birth to a baby, call it natures efficiency.

Are their any other better solutions in the name of evolution?

mic drop.

What are the societal, physiological and even epigenetic effects of smart phones/social media/internet culture in the last ten years? Any decent books on the subject?

So the richest man of the world had completed his joyride into space.

We need socialism bros...

Its storming fairly bad. Pretty frequent lightning, but none that I remember at the time I saw the weird thing.
I was just stopped at a red light in the rain, and my attention was drawn to the powerlines above and to my right. There were 3 or 4 white/blue glowing football shaped objects traveling slowly in a row along one of the powerlines. The line ran through the center of each object, and where the line came out of it, the things narrowed down, giving them the football shape. Id say they were probably half the size of an american football, moving no faster that walking speed along the line.
The light turned green and i had to drive on but i got a good 4 or 5 second look.

Scibros please help me figure this out. Its this a normal but rare power line thing?

do you look like a scientist?

How can we get rid of the politically motivated, reactionary and backward pseudoscientific theories like race realism?

Can rational scientific discussion be fully relied upon or we need political action on the fascist supremacists that spread these lies?

Hereditarianism, evolutionary psychology and Behavioral genetics have been total disgrace to science and have spread nothing but vitriolic hate.

Isn't it good for everyone that decades old false data and research be completely discredited and public should be re-educated in these fields from a new better, more rational and progressive perspective?

Scientifically speaking, why is it that you can tell whether someone is a midwit by their face?

Why is the sun so much warmer in the west coast compared to the eastcoast? Picrel goes in the sky of both location in the same matter yet is hotter in California than New York.
