How could the pilots have missed or disregarded all of these potentially salient clues? Several factors likely contributed, but it’s worth noting first of all that humans tend to judge whether a situation looks “wrong” based on what we’re expecting to see, rather than objectively analyzing whether everything that should be there is in fact present. - https://admiralcloudberg.medium.com[..]ngapore-airlines-flight-006-61128fc6b8ee

What is asexual reproduction: nature’s virgin birth - https://www.zmescience.com[..]exual-reproduction-natures-virgin-birth/ Biology-mysteries - http://list25.com[..]manity-has-not-figured-out-yet/?view=all Over 50 years ago, researchers circumnavigated the Americas sampling ocean life along the way at regular intervals. In the process, they discovered a striking relationship: the abundance of a certain marine species is linked to its body size such that its collective mass is basically the same. Krill are a billion times smaller than tuna, but their numbers are a billion times more abundant. If you were to weigh all the krill in the ocean, the mass should be close to all the tuna — but not anymore. - https://www.zmescience.com[..]umans-broke-a-natural-law-of-ocean-life/ Scientists are stunned by the discovery of the world’s largest bacterium.
