полоски зебры служат не только камуфляжем от хищников, но и для отпугивания кровососущих насекомых

Выяснилось, что полоски зебры служат не только камуфляжем от хищников, но и для отпугивания кровососущих насекомых. Полоски не мешают мухам и слепням находить жертву, тут они справляются, но проблемы возникают при посадке: у насекомого "сбивается" оптика. Муха оценивает скорость, с которой визуальные контуры объекта расширяются в ее поле зрения, и на основе этого автоматически корректирует свою скорость, чтобы вовремя затормозить.

В СССР была самая лучшая медицина? Да, все познаётся в сравнении!

Health & Medical.

США, 1925 год.

Врач говорит пациенту, что он выглядит изможденным, и выписывает ему тонизирующее средство. Это дистиллированная вода с радием. Продано четыреста тысяч бутылок с медицинской рекламой, а сталелитейный магнат по имени Eben Byers, выпивший полторы тысячи, похоронен в 1932 году в свинцовом гробу. https://en.wikipedia.org/wiki/Eben_Byers

Перед смертью Eben Byers весил около 40 кг. Ему полностью удалили почти всю верхнюю челюсть и часть нижней, а в костях черепа образовались отверстия.

Немного этимологии

Linguistics.

Ангел — просто вестник. В «Илиаде» angelos — это обычный человек, приносивший известие.
Энтузиазм — религиозный экстаз. Буквально en — внутри, theos — бог. Шоссе Энтузиастов недоумевает.
«Симпозиум» — совместное распитие спиртных напитков. Из древнегреческого (syn - вместе, с и posis — пью). Ученые прекрасно это знают и сами. Syn звучит во множестве слов, например в симфонии + phone — голос.

Civil Rights Icon Cesar Chavez's Family, Officials React To Sexual Assault Accusations
Well he is dead, so he can't defend himself against such "allegations" now, can he? Therefore, accusations must be treated as proven facts.

The mindset as near as I can tell is to just put people to work, who cares if it's useful or generates a profit.
"Eu gostaria de pagar seus salários": Elon Musk oferece linha de vida para agentes TSA como democratas manter cheques de pagamento reféns em encerramento
I didn't read the article, but commenting on the title. Isn't this like giving heroin to a junkie?

And what's up with fascism, what's up with private individuals meddling with government affairs? We want our government to be a highly-functioning one. Instead we got an autistic government. So, instead of fixing the government, we're supposed to allow billionaires to give the government a hand-out?

Now the government gives hand-outs to everybody. Millionaires give hand-outs to governments. And our society... What of it? Completely collapsed and destroyed?

Fix the government, fix corruption. And stop with the idea of free money - there is no such thing.
