[Archaeo - Histories @archeohistories]

In 1980, a bioarchaeologist at Emory University named George Armelagos was studying ancient human bones from Sudanese Nubia, the kingdom that flourished along the Nile south of Egypt between roughly 350-550 CE, when something stopped him. Under ultraviolet light, the bones glowed.

They fluoresced with a distinctive yellow-green color that Armelagos recognized immediately, because the same glow appeared in the bones of modern patients who had been treated with tetracycline.

The antibiotic binds tightly to calcium and phosphorus in bone tissue as the body metabolizes it, leaving a permanent fluorescent marker. What Armelagos was seeing in bones nearly two thousand years old was chemically identical to what he saw in twentieth-century medical subjects.

The archaeological community was skeptical. The received history of antibiotics began with Alexander Fleming’s discovery of penicillin in 1928, and tetracycline itself was not isolated until 1948. The idea that a pre-literate population in the Nile valley had been routinely ingesting it seemed implausible, and the initial findings were dismissed as post-mortem contamination from soil bacteria.

Armelagos spent three more decades building the case. He eventually partnered with Mark Nelson, a leading tetracycline specialist at Paratek Pharmaceuticals, who agreed to perform a definitive chemical analysis.

The process required dissolving the ancient bones in hydrogen fluoride, one of the most corrosive and dangerous acids in existence. What the resulting liquid-chromatography mass-spectrometry analysis found was not a trace of tetracycline.

The bones were saturated with it. Multiple tetracycline variants were identified, including chlortetracycline and oxytetracycline, in concentrations indicating sustained exposure beginning in early childhood and continuing throughout life.

Ninety percent of the Nubian individuals tested showed the labeling. The exposure had not been accidental or occasional. It had been lifelong and deliberate.
The source was their beer.

Ancient Egyptian and Nubian brewing began with grain, typically emmer wheat or barley, which in that region was naturally contaminated with Streptomyces, a soil bacterium that produces tetracycline as a metabolic byproduct.

The grain was germinated, made into bread, then incompletely baked to preserve an active center, and finally fermented in vats of water. The standard practice was to seed each new batch with ten percent of the previous one, which kept the Streptomyces culture alive and active from batch to batch in a continuous chain.

The resulting brew was thick, sour, low in alcohol, and highly nutritious. Everyone drank it, including children as young as two years old.

The critical question Armelagos could not fully resolve was whether the Nubians understood what they were doing. The consensus among researchers is that they almost certainly did not know the mechanism.

They had no concept of bacteria, no understanding of antibiotics as a drug class, and no language for what tetracycline was doing in their bodies.

What they likely did know, accumulated through generations of observation and passed down as practical knowledge, was that this particular preparation of beer had medicinal effects.

Ancient Egyptian and Jordanian medical texts record beer being used to treat gum disease, wounds, and other infections.

The brewing method that produced tetracycline appears to have been deliberately maintained and refined over centuries, not by any understanding of the chemistry involved, but by the accumulated recognition that it worked.

Essa aqui é a famosa Carne de Onça e ela tem esse nome porque a reprodução de onças-pintadas no Paraná é tão intensa que criaram um prato à base do animal para controlar sua população.

🚨🚨 ATENÇÃO 🚨🚨

Custo dos "penduricalhos" de juízes e desembargadores em 2025 já supera o de 5 programas sociais inteiros

Esses "penduricalhos" são pagos a apenas 18,9 mil magistrados

Já custaram mais que o Pé-de-Meia; o Seguro-Defeso, o Auxílio-Gás e outros 🧶

Não tenha planos de telefonia da TIM !!!

No início de Abril, a @TIMBrasil
Permitiu que um estranho ativasse meu número de celular em outro chip.

Trata-se de um número que eu tinha há 10 anos, com plano pré-pago.

A Tim alega não ter o registro da solicitação de mudança de planos.

Alegaram também que dentro de uma semana iriam enviar um e-mail com a apuração interna.

Obviamente, não apuraram nada.

Em conversas com amigos advogados, descobri que há mais de 100 mil casos similares na justiça.

A TIM é a única operadora a coadunar com este tipo de fraude.

Para que um golpista roube seu número, ele precisa apenas de alguns poucos dados seus.

No dia de hoje, em audiência de conciliação, a TIM nada propôs.

Há 2 meses, a empresa não conseguiu devolver a linha, que foi bloqueada por decisão da justiça.

Nada mais restando, fica o conselho:

Cancele seu plano da TIM. Fuja desta empresa. Não aguarde ser vítima de fraude para isso.
