A group of researchers say they have pinpointed the ancestral homeland of all humans alive today: modern-day Botswana. Based on analyses of mitochondrial DNA, the researchers concluded that every person alive today descended from a woman who lived in modern-day Botswana about 200,000 years ago.
Simpatia para ter bons negócios Antes de se deitar, imagine que os negócios que você tem para resolver estão bem-encaminhados com a divina luz da Rainha da Paz e que seus empreendimentos vão render bons lucros. Depois disso, bata três vezes o pé direito no chão, dizendo: “Meus negócios já estão encaminhados e nada impedirá que eles deem certo, minha querida Rainha da Paz”. Deite-se e reze

Black holes are famous for ripping objects apart, including stars. But now, astronomers have uncovered a black hole that may have sparked the births of stars over a mind-boggling distance, and across multiple galaxies.
Israeli cave finds challenge our theories about evolution’s winners and losers. Because the archaeological evidence shows that homo sapiens lived in the area between 115,000 and 75,000 years ago. Neanderthals lived in the area around the same time, successfully maintaining a population without interbreeding with the neighboring homo sapiens.
Homo sapiens are thinner, adapted for warmer and wetter climates. Neanderthals are stockier and carry more heat, adapted for cooler and drier climates. So when the climate of the area changed, steppe-glaciers advancing and forests disappearing, homo sapiens retreated while Neanderthals stayed. It’s unclear if the homo sapiens living in the area died out, or moved south to more favorable climes. The archaeological record does not say.
But we do know that it about 5,000 years later, around 60,000 years ago, homo sapiens sent a second successful wave of settlers into the area. And of course, in the long run, the Neanderthals were the ones who died out. But the evidence from Israel’s caves show that outcome was not always inevitable.
In about 250 BCE, a Celtic tribe known as the Parisii first settled Paris on the Île de la Cité. In 52 BCE, the Parisii settlement was conquered by the Romans and their general, Julius Caesar.
The Romans named the city Lutetia, from an earlier Greek name Lukotokía, whose origin is unknown. But the renaming did not stick. So the city of lights is known today as Paris, the name of its first founders, from over 2,200 years ago.
Americans are now most likely to have met their romantic partners online, which was of course impossible just a few decades ago. They are also taking longer to move in together, and to marry, than ever before.

Sweden fought in its last war in 1814, and Switzerland fought in its last war in 1815. So although Swiss neutrality is more famous, Sweden’s neutrality is older.
For those interested, Sweden’s last military action was an invasion to force Norway under Swedish control. Switzerland’s was fighting on Napoleon’s side until Waterloo.
Neither Sweden nor Switzerland participated in either world war, and today, neither are members of NATO.

An astonishing late Bronze Age collection of swords, axes, spearheads and bracelets were found in Havering, in East London, in 2018. With 453 items it is the 3rd-largest hoard ever found in England! And the largest ever found in London. The Havering Hoard was uncovered as part of routine archaeological excavations before the land was opened up for gravel extraction.
The bronze axe heads and spear heads are shown here; they date to between 800 and 900 BCE.
Technically, she was known as Diego Rivera’s partner – an exotic eccentric. Her own work, while selling in her final decade, was often overshadowed by her Bohemian reputation, and her dressing in traditional Mexican costume. She could not live off her art until late in life.By 1953, such was her declining physical state that for her first Mexican solo show, her four poster bed was taken from her house to the gallery. Kahlo arrived by ambulance and was transferred from the ambulance to a stretcher to her bed.
She died in 1954, and her work as an artist was left to languish until it was rediscovered in the 1970s by art historians and political activists. As you know, she is now a worldwide household name. Quite a life-after-death.
In his seminal work, On the Origin of Species, Darwin wrote that bumblebees are the only pollinators of red clover. In 1862 he discovered that this is wrong. Honeybees also pollinate red clover well.
He wrote to his friend John Lubbock, “I hate myself, I hate clover, and I hate bees.”

Jamaican Violet Brown was the oldest verified living person for 5 months. She got the crown at age 117, after the death of Emma Morano on April 15, 2017.
Brown’s first child, Harland Fairweather, was 97 years old and was believed to have been the oldest person with a living parent. But he died just a few days later, on April 19th, 2017. Still, pretty cool to have a mother-and-son record like that!
In the Phoenix Constellation, astronomers have confirmed the first example of a galaxy cluster where large numbers of stars are being born at its core.
Thirty-one objects thought to have belonged to one warrior have been found in a cache in northeastern Germany’s Tollense Valley, where an intense battle was fought by as many as 2,000 warriors around 1,300 BCE. The warrior’s kit included a bronze awl with a birch handle, a knife, a chisel, a decorated belt box, three dress pins, arrowheads, and fragments of bronze that may have been used as currency. Three thin bronze metal cylinders pierced with bronze nails found with the kit may have been fittings for a cloth bag or wooden storage box which degraded, leaving only its metal fittings.
The bronze items in the warrior’s kit are similar to those found in southern Germany and the Czech Republic, and combined with the chemical analyses of multiple warriors’ bones suggesting they did not grow up locally, it is thought that perhaps warriors from multiple regions came together in this valley to fight over trade routes along the Tollense River.
That is the image of a lost city, found beneath the Cambodian jungle. Mahendraparvata, sometimes dubbed the ‘lost city of Cambodia’, was an early capital city of the Khmer Empire (800s - 1400s CE). Historians and archaeologists knew Mahendraparvata existed – somewhere. And a recently-released paper suggests that it has been found, based on the combination of scriptural evidence stating the capital was on a specific mountainous plateau, and airborne laser scanning (above) that found the remains of a city in that area.
Traditional ground-based archaeological work was conducted after the laser scanning identified the site. The city appears to date to the late 700s CE to early 800s CE, the right era for Mahendraparvata. It is a city of linear axes denoting wide boulevards. The streets are large, 60 to 80 meters (~200 feet) wide, and up to 15 kilometers (9 miles) long. Dams, reservoir walls and the enclosure walls of temples, neighborhoods and even the royal palace are built next to or alongside the embankments.
With thousands of buildings Mahendraparvata will take decades to fully rediscover. This was a large city, a capital city, built to impress even centuries later.

This may be a female shaman. This fragment of an earthenware vessel inscribed with a possible drawing of a woman shaman wearing a bird costume was uncovered in western Japan at Shimizukaze, a site dating to the middle of the Yayoi Period, around 100 BCE.
Nineteen other earthen vessels inscribed with human figures with outstretched arms have been unearthed across Japan, but this is the first to appear to have breasts. Her eyes, nose, mouth, and one arm with five fingers are also visible on the fragment, which measures just 5 inches by 6.5 inches.
Simpatia para ter mais clientes na sua loja Pegue alguns grãos de arroz, de soja, de feijão, de milho e jogue um punhado de cada um deles num canto de sua loja dizendo: “Fartura há de vir com as graças da boa-ventura. Fartura há de vir com o trabalho da semeadura”. Diga essas palavras ao abrir a loja ou seu negócio durante um mês. Ao sair, reze um Pai-Nosso em agradecimento.

Many galaxies we see through telescopes such as the NASA/ESA Hubble Space Telescope, the source of this beautiful image, look relatively similar: spiraling arms, a glowing center, and a mixture of bright specks of star formation and dark ripples of cosmic dust weaving throughout. This galaxy, a spiral galaxy named NGC 772, is no exception.
Well-done video showing where in the ancient world the Chinese historians were describing, and examples of what they were (probably) describing.
It’s rather amusing what the Chinese thought were important: being able to breath fire and juggle 10 balls, relay sheds for postal stations, and many, many types of cloth.
This is the cubit rod (aka ruler) of Maya, “treasurer of king Tutankhamun.” He also served under Tutankamun’s two successors, Ay and Horemheb. The cubit rod was an important part of being a treasurer because the Egyptian government was built on land management, and taxes were mainly agricultural products. To know how much to tax, you had to know how to measure the field, and the unit of measurement was the cubit.
This rod measures the royal cubit of seven palm-lengths (52.3 cm) and the common cubit of 6 palm-lengths. There are also a number of gradations shown including “digits,” palm-lengths, and fractions of digits from halves to sixteenths. Just in case Maya needed to measure really small distances.

Archaeologists have recovered a rare and tantalising treasure just 160 feet offshore from Mallorca in Spain. Not gold or jewels, but 93 jug-like terracotta vessels called amphorae from a Roman ship that sank 1,700 years ago.
The amphorae are still intact and some are even sealed. So there is a pretty good chance that their contents survived the millennia. The amphorae are currently undergoing desalinization in a lab, to make sure that the salt doesn’t crystallize, breaking the amphorae and destroying their contents. But once that’s finished there will be some exciting news in the archaeology world!
Name tags (in Korean: hopae) were, at times, legally required for all adult males under the Joseon government. First introduced in 1413 by King Taejong they were apparently modeled after a similar system under the contemporary Yuan Dynasty. Hopae were required on and off until the early 1600s, usually when the government saw the need to control internal migration. The tags are made of wood or horn, and showed the man’s name plus other required identification. Some also included rank and permissions.
These particular tags belonged to soldiers. They list the soldiers’ name, year of birth, year of entering service, position, and place of residence/troop. The last two on the right were for two brothers, both cannoneers (別破陣).
Obscure engravings on animal bones from the site of Lingjing in Henan Province suggest that early hominins who lived there 125,000 years ago may have had more advanced cognitive abilities than once believed. The mysterious markings proved to have been etched into the bone. The bone was then rubbed with red ochre powder to make the markings more visible. It is unknown why they made these marks, or what they represent.
James Buchanan was born in 1791. He was the 15th president of the United States, and his two immediate predecessors were both born after 1800 (13th president Millard Fillmore in 1800, 14th president Franklin Pierce in 1804). Buchanan is the only US president whose century-of-birth preceded that of the president before him.
Simpatia para afastar pessoas egoístas Espete uma espada-de-são-jorge em um vaso que tenha em sua casa. Depois de sete noites, retire a planta, como se estivesse retirando as pessoas egoístas de sua vida. Jogue a planta no lixo e reze um Pai-Nosso e uma Ave-Maria. Lembre-se sempre de lavar bem as mãos após entrar em contato com a planta, já que ela é tóxica.

Since 1219, Estonia was ruled at various times by Danish, Swedish, German, and Russian governments. It declared independence after World War I, but that only lasted until 1940 when it was occupied by the Soviet Union. Estonia has only been an independent nation since 1991.
That means that since 1219, Estonia has been independent for exactly 50 years out of 800!

Did you know that Christ the Redeemer, the iconic statue that looms over Rio de Janeiro, was finished in 1931? The 130-foot reinforced concrete-and-soapstone statue sits atop the peak of the 700-meter (2,300 ft) Corcovado mountain in the Tijuca Forest National Park.
The statue cost approximately US$250,000 to build. That’s 3.5 million in today’s dollars. It was built mainly on donations, too. So thank goodness the project was started in 1922, giving them plenty of time to raise donations before the Great Depression hit!

Portrait of a woman (potentially Mary Magdalene) by Lucas Cranach the Elder.
The artist used contradictory symbolism in this painting, making identification a little difficult. Her hair is loose, signalling an unmarried virgin, but her direct gaze was inappropriate for an unmarried woman of a respectable family. Lucas Cranach the Elder was a great German artist painting for 16th-century aristocratic patrons. His paintings had to be respectable, able to be hung in the most eminent homes. That leaves the most likely subject the biblical Mary Magdalene, who was supposedly once a prostitute before converting.
