Reply to comment by jubears09 in Is there a genetic disease where the heterozygote has more severe disease symptoms than the homozygote? by Altranite-
So if I understand the abstract from the PCDH19 link, the problem isn’t heterozygosity on a cellular level, so much as random X-inactivation causing regions of incompatible homozygous (hemizygous?) cells. Is that correct?

> Starting Y-axis near the lowest value can make insignificant differences look massive
It’s worse than that: if you’re just comparing two values, the resultant graph will look exactly the same regardless of what the input values are. The graph is conveying no information whatsoever.

Is it necessarily a bad thing that we pay more attention to dissenting opinions during a discussion?

Reply to comment by DrJGH in Sheep flocks operate as a type of ‘collective intelligence’ and elect temporary leaders to guide them while moving. The fluidity of this process is extremely surprising. by nimobo
I wonder if there’s a difference between domestic and wild sheep—maybe the behavior of domestic sheep has evolved to function in conjunction with shepherds and dogs.

> The size doesn’t matter.
Real estate inside the skull is expensive, evolutionarily, and humans have sacrificed a lot to maximize brain volume. If it were possible to see as well with bird-sized eyes, why haven’t we already evolved them in exchange for bigger brains?

Cats have better night vision than we do because they’ve traded cone cells for rods—so they have higher resolution and dynamic range in their grayscale vision at the expense of being red/greed colorblind.
But if you scaled up a cat’s eye to human size, it seems like it should be even better—similar to a camera with a bigger objective lens and/or ccd. Unless I’m missing something?

Does Redding get its name from being the only place in the west where the leaves turn red?

Reply to comment by Andromeda321 in Gaia discovers a new family of black holes: astronomers studied the orbits of stars and noticed that some of them wobbled on the sky, as if they were gravitationally influenced by massive objects. No light could be found using several telescopes, leaving only one possibility: black holes. by Andromeda321
How common is it to have enough observations of a star to be able to detect this kind of wobble in its orbit?
Does this affect our estimate for the overall prevalence of black holes, if the first one discovered by this method isn’t emitting the x-rays we’ve used to find the other currently-known ones?
