Morte por ouro derretido

  No filme Goldfinger de James Bond, há uma cena em que o vilão excêntrico mata uma mocinha de uma maneira digna de vilões de James Bond. Ele pinta todo o corpo da pobre donzela com ouro, e ela morre por… asfixia! Isso porque, oras, você devia saber, nós também respiramos pela pele. Dançarinas profissionais que costumam pintar o corpo costumam deixar uma parte na base da espinha sem pintura justamente para evitar a asfixia. É uma fabulosa lenda, mas é apenas uma lenda, isto é, é falsa, não é verdade. Respirando normalmente pelo nariz, você não deve morrer asfixiado, por mais que feche todos os poros de sua pele com ouro ou outras formas um tanto menos caras. O principal problema com que pode se deparar é que a tinta sim impedirá a transpiração. Você não irá suar e a regulação de temperatura corporal não funcionará corretamente. Se você poderá morrer por causa disso é outro assunto, os Mythbusters, ou Caçadores de Mitos, dedicaram-se ao tema várias vezes, sempre interrompendo os testes após alguns minutos. Se a morte pela pintura do corpo com ouro é um tema incerto, a execução através do derramamento de grandes quantidades de ouro derretido garganta abaixo é muito certa. No fim do século 16, um governador espanhol no Equador colonial foi morto por membros da tribo Jívaro – mais conhecidos por criar miniaturas de cabeças – exatamente desta forma. Como os pesquisadores holandeses Goot, Berge e Vos notam, despejar metais derretidos goela abaixo das vítimas era em verdade uma prática levada a cabo nos dois lados do Atlântico, dos Romanos a, ironicamente, a Inquisição Espanhola. “Várias fontes mencionam a explosão de órgãos internos. A questão permanece se este é realmente o caso e qual seria a causa da morte”, escrevem os pesquisadores. “Para investigar isto, obtivemos uma laringe bovina de um matadouro local. Depois de fixar a laringe em posição horizontal a um pedaço de madeira e fechar o fim distal com papel higiênico, 750 g de chumbo puro (ao redor de 450 graus) foi aquecido e despejado na laringe”. São métodos curiosamente similares aos praticados pelos Mythbusters (ou vice-versa). Afinal, as infelizes vítimas acabam mesmo explodindo? Fique conosco para que Adam e Jamie, digo, Goot, Berge e Vos contem os resultados na continuação. Não se preocupe, não há nenhuma imagem chocante.

Friday Weird Science: The Stuttering Priapism

Who would have thought Sci would be running a normal pub-med search, for something COMPLETELY not weird science material, and come across...this? Truly, it was meant to be!

This case report is probably one of the weirdest things I've seen all week, and kept Sci scratching her head as to the possible mechanism. Also, it is, without a doubt, one of the most incredibly embarrassing thing to ever happen to a 15-year-old. And you thought YOUR teenage stories were bad...

Remember, Remember the Fifth of November [The Primate Diaries]


Remember, remember the fifth of November,
The gunpowder treason and plot,
I know of no reason
Why the gunpowder treason
Should ever be forgot.

On this day, in 1604, Guy Fawkes was arrested in his attempt to overthrow the English monarchy by blowing up the House of Lords and assassinate King James I (who would have been present at the time). Since his arrest Fawkes' crime has been condemned as terrorism motivated by fanatical Catholic outrage against the Protestant regime of James I. However, is the religious angle enough to explain his actions and those of his conspirators? What was at the root of his discontent and is there anything we can learn today from this event, more than four hundred years ago?

Antivirals and resistance: Adamantanes

In the case of a pandemic, and during the seasonal epidemics, once a person has already contracted the influenza, we can do little, other than monitor and treat him with antivirals. However, they are not always a guarantee of success, especially in the case of resistant viruses.

It’s Not Just Carbon

Most of the discussion of climate change and options for mitigating it has focused on carbon dioxide emissions and the potential for reducing them.  This is reasonable enough, since carbon dioxide is by far the most abundant greenhouse gas, and it’s fiendishly difficult to do anything about once it’s emitted.  It stays in the atmosphere [...]...
