PreHistoric Murder Uncovered!

In northern Spain about 430,000 years ago, the bodies of at least 28 early humans found their way to the bottom of a 43-foot-deep shaft in the bedrock that archaeologists call Sima de los Huesos, or “Pit of the Bones.” They were not humans, but rather evolutionary precursors of Neanderthals, which modern scientists have named Homo heidelbergensis. Several explanations have been proposed: Carnivores might have dragged them there, or perhaps 28 separate hapless hominins accidentally fell down the shaft. But we know at least one was a murder victim!

Nohemi Sala, a paleoanthropologist, was studying the breakage pattern of some of the bones from Sima de los Huesos. She noticed something a bit unusual. Most breaks had occurred over the millennia that the bones sat in the ground, but one skull had some very distinctive damage. It appeared to Sala that two of the breaks, on the forehead, had happened while the person was alive. But there were no signs the breaks healed either.  Each break was likely made with a blunt object. And either would have been deadly on its own – meaning this wasn’t a hunting accident (which would have had just one break) or a bad suicide attempt (for the same reason). Put together, it suggests the person was attacked, and died from the assault. Often, cause of death is not clear just from bones, so one of the skeletons having clearly been a murder victim does suggest that others in the pit might have meet untimely ends, as well. What does this say about Homo heidelbergensis? Sala says the evidence is both good and bad. There is a capacity for violence there. But there is also care for the dead. The murder victim was not left where he fell, but removed and buried where others had been buried before him

Vídeo mostra assombração em IML de Cuiabá

Um vídeo publicado na internet mostra o que parece ser um fenômeno paranormal ocorrendo em um local que se supõe ser o Instituto Médico Legal (IML) de Cuiabá, no Mato Grosso.

No vídeo, a porta de um hidrante bate sem parar e as luzes piscam indicando a presença de uma força sobrenatural. Nas redes sociais, há quem acredite e há quem aposte em montagem (ou até teaser para algum novo filme).

O jornal Extra, entretanto, afirma que as imagens foram gravadas no Centro de Atendimento Integral à Criança e ao Adolescente de Araucária (CAIC), no Paraná, e que seus autores já foram localizados.

“A direção da unidade confirmou ao EXTRA que o registro foi feito por guardas noturnos no último domingo enquanto verificavam o que estaria provocando o abrir e fechar de uma porta”, diz a publicação.

Apesar da contradição no local das filmagens, a assombração que aparece no vídeo não parece ter sido forjada. Por enquanto, ninguém soube explicar o que ocorreu naquele local.

March 14th 1794: Eli Whitney patents the cotton gin

On this day in 1794, American inventor Eli Whitney recieved a patent for his cotton gin. Whitney, who was born in New England, moved to Georgia in 1792 to work as a tutor on a plantation. Whitney witnessed the system of Southern slavery firsthand, and noted that the growing of cotton - a staple crop on slave plantations - was becoming unprofitable. The one strain of cotton which grew inland had sticky green seeds which were time consuming to pick out of the fluffy cotton balls. Whitney sought to build a machine which would speed up this process, therefore ensuring the continued viability of the Southern cotton-based slave economy. The result of his efforts was the cotton gin, which could separate the seeds from the cotton at speed. Whitney patented his invention in 1794, and with his business partner installed them throughout the South and charged planters for their use. Planters, who resented paying the high price for using the gin, exploited a loophole in the patent law and made their own versions of the machine. The invention of the cotton gin made a significant impact upon the Southern economy and, indeed, the course of American history. After the invention, the yield of raw cotton doubled each decade after 1800, ensuring the continued profitability of slavery in the United States and leading to the growth of American slavery. Using machines of the Industrial Revolution to refine and spin cotton, grown by enslaved people who were not paid for their labour, the United States soon became the world’s leading supplier of cotton. Historians sometimes claim the invention of the cotton gin as a pivotal moment in the coming of the American Civil War. The invention ensured that the evil of slavery continued in the American South, setting the nation on the course to war over the ‘pecular institution’.
