I’ve always thought it would be really cool to compare individuals in a long-term nestbox study with those beyond human interaction, to look for a ‘domestication’ effect. Would you see these differences? Sequence differences?
New paper: in urban great tits, epigenetic changes in the DRD4 gene help explain tolerance to human disturbance, influencing vigilance and return behavior after disruption

The oldest known image of an owl:
More than 30,000 years ago, someone skillfully scratched the figure of a long-eared owl (Asio otus) into the soft outer layer of the walls of Chauvet Cave, France. The owl is looking backward over their wings, head turned 180 degrees

Well, that’s exactly what this juvenile jack is doing! Mostly immune to its sting, the jack has taken the jellyfish prisoner.

Only 10 cases of Guinea worm disease were recorded *globally* last year.
It may become the second human disease we eradicate, after smallpox.

5️⃣ Watson & Crick 1953 paper was not peer reviewed.
It was not until 1973, when David Davies was hired as Nature's editor, that peer review became a requirement for every paper printed there.

When I think about measles I think about the number 1,000. Thats the number that epidemiologists use to explain harm from measles in children. With 1,000 cases, about 200 children will require hospitalization, 50 will develop pneumonia, and one to three will die.
South Carolina is at 789.

On the subject of penguins and madness, did you know that 9 King Penguins were released in 1936 in Arctic Norway by the Norwegian Nature Protection Society? At least a couple possibly survived until 1944. So for a brief period Polar Bears and penguins could in theory have met. #biologicalinvasions
