I agree with almost all the points, especially the last one. The first half of the gallery is mind blowing and really focused. The second half is as if someone decided that "we cannot just show photos from STEM fields, we need to add some human touch of social sciences" (which, having worked for a major scientific publisher in the past, I am will to bet was exactly what has happened).
Re. them being over-edited - I wonder if the reason for that is because many of those would not have any colours in them if it wasn't for the editing (because they were taken using X-rays for example).
