A 3,400-year-old tomb holding the remains of more than a dozen possibly mummified people has been discovered on Sai Island, along the Nile River in northern Sudan.
Archaeologists discovered the tomb in 2015, though it wasn't until 2017 that a team with the AcrossBorders archaeological research project fully excavated the site.
The island is part of an ancient land known as Nubia that Egypt controlled 3,400 years ago. The Egyptians built settlements and fortifications throughout Nubia, including on Sai Island, which had a settlement and a gold mine. The tomb, which contains multiple chambers, appears to hold the remains of Egyptians who lived in or near that settlement and worked in gold production.
The artifacts found in the tomb include scarabs (a type of amulet widely used in Egypt), ceramic vessels, a gold ring, the remains of gold funerary masks worn by the deceased and a small stone sculpture known as a shabti. The ancient Egyptians believed that shabtis could do the work of the deceased for them in the afterlife. Some of the artifacts bore Egyptian hieroglyphic inscriptions that revealed the tomb was originally created for a man named Khnummose, who was a "master gold worker."
The remains of Khnummose (which may have been mummified) were found next to those of a woman who may have been his wife. Some of the other people found in tomb may have been relatives of Khnummose, the researchers said, adding that they planned to conduct DNA analyses of the remains.

First complete genome data extracted from ancient Egyptian mummies
Study finds that ancient Egyptians were most closely related to ancient populations from the Middle East and Western Asia.
An international team of researchers have successfully recovered and analysed ancient DNA from Egyptian mummies dating from approximately 1400 BCE to 400 BCE, including the first genome-wide data from three individuals. The study found that modern Egyptians share more ancestry with sub-Saharan Africans than ancient Egyptians did, whereas ancient Egyptians were found to be most closely related to ancient people from the Middle East and Western Asia.
This study counters prior scepticism about the possibility of recovering reliable ancient DNA from Egyptian mummies. Despite the potential issues of degradation and contamination caused by climate and mummification methods, the authors were able to use high-throughput DNA sequencing and robust authentication methods to ensure the ancient origin and reliability of the data. The study, published in the journal Nature Communications, shows that Egyptian mummies can be a reliable source of ancient DNA, and can contribute to a more accurate and refined understanding of Egypt’s history.
Egypt is a promising location for the study of ancient populations. It has a rich and well-documented history, and its geographic location and many interactions with populations from surrounding areas, in Africa, Asia and Europe, make it a dynamic region. Recent advances in the study of ancient DNA present an opportunity to test existing understandings of Egyptian history using ancient genetic data.
However, genetic studies of ancient Egyptian mummies are rare due to methodological and contamination issues. Although some of the first extractions of ancient DNA were from mummified remains, scientists have raised doubts as to whether genetic data, especially the nuclear DNA which encodes for the majority of the genome, from mummies would be reliable, and whether it could be recovered at all.

The Controversial Afterlife of King Tut
A frenzy of conflicting scientific analyses have made the famous pharaoh more mysterious than ever
By Matthew Shaer for Smithsonian Magazine
The Valley of the Kings lies on a bend in the Nile River, a short ferry ride from Luxor. The valley proper is rocky and wildly steep, but a little farther north, the landscape gives way to gently rolling hills, and even the occasional copse of markh trees. It was here, in a humble mud-brick house, that the British Egyptologist Howard Carter was living in 1922, the year he unearthed the tomb of the pharaoh Tutankhamun, forever enshrining both the boy king and himself in the annals of history.
These days, the house serves as a museum, restored to its nearly original state and piled high with Carter’s belongings—a typewriter, a camera, a record player, a few maps, a handful of sun hats. Toward the back of the museum is a darkroom, and out front, facing the road, is a shaded veranda.
On the September day I visited, the place was empty, except for a pair of caretakers, Eman Hagag and Mahmoud Mahmoud, and an orange kitten that was chasing its own shadow across the tiled floor.
Most of the lights had been turned off to conserve electricity, and the holographic presentation about Carter’s discovery was broken. I asked Hagag how many visitors she saw in a day. She shrugged, and studied her hands. “Sometimes four,” she said. “Sometimes two. Sometimes none.”
Mahmoud led me outside, through a lush garden overhung with a trellis of tangled vines, and toward the entrance of what appeared to be a nuclear fallout shelter. An exact replica of Tutankhamun’s tomb, it had opened just a few months earlier, and Mahmoud was keen to show it off.

The truth about Tutankhamun (2)
In the second of two articles, Zahi Hawass continues his explanation of the mystery of Tutankhamun
November 2014 marks 92 years since the discovery of Tutankhamun’s tomb in Luxor. This is an occasion that could be used to promote tourism to the city where the golden king and his tomb are located. It is also be an ideal opportunity to announce that only one ticket is now needed to visit Tutankhamun’s family tombs, including those of Amenhotep II, Yuya and Tuya, and tomb KV55.
Even with the passage of time, we should never forget what the English team did to the pharaoh’s mummy in 1968. Jewellery disappeared, and pieces of the mummy were taken without permission. Only last year an English team announced, based on their examination of these stolen pieces, that the mummy of Tutankhamun had been burned.
My intention in this article, and in the article published in the Weekly last week, is to show that despite the problems that Tutankhamun had during his life, he was in good health and used to hunt wild animals. He was not disabled, contrary to what was alleged on a recent TV show.
Last week I wrote about the lies told in an English TV show about the golden king, and how a scientist had perjured himself in front of scholars all over the world. The truth about Tutankhamun is the real discovery made by the great British archaeologist Howard Carter, enabling us to discover new material about the boy king every year. The truth has been revealed by the great work of the Egyptian Mummy Project and the discovery of Tutankhamun’s family and how he died.

How Studying Mummies Could Cure Modern Diseases
By comparing diseases from then and now, researchers can learn how they spread. Maybe they can learn how to stop them, too.
By Roxanne Khamsi
Earlier this year, scientists published a study of whole-body CT scans of 137 mummies: ancient Egyptians and Peruvians, ancestral Puebloans of southwest America, and Unangan hunter-gatherers of the Aleutian Islands. They reported signs of atherosclerosis—a dangerous artery hardening that can lead to heart attacks or stroke—in 34 percent of them. What struck the research team, led by Randall Thompson of Saint Luke's Mid America Heart Institute in Kansas City, Missouri, was that it afflicted mummies from every group. Frank Rühli, head of the Swiss Mummy Project at the University of Zurich, also sees the condition in about 30 to 50 percent of the adult specimens he studies. The breadth of these findings suggests that atherosclerosis today may have less to do with modern excesses such as overeating and more with underlying genetic factors that seem present in a certain percentage of humans living almost anywhere in the world. Someday, identifying those genes could lead to new drugs for heart disease.
Ancient mummies can provide a wealth of information about the health of early civilizations, which may help us better treat diseases today. But because mummies are both rare and delicate, researchers have been limited in what they could do to them—and therefore what they could learn from them. Recent improvements of two medical tools—DNA sequencing, which can reveal microbial infections, and CT scanning—are letting paleopathologists diagnose mummies' causes of death in detail. They're now finding signs of everything from prostate cancer to malaria in mummies across the globe. By comparing the ancient forms of those diseases with their contemporary equivalents, researchers can learn how those diseases evolved, what makes them so harmful, and—possibly—how to stop them.

The Mummy Code
Ancient-DNA researchers have long clashed over work on Egyptian mummies, but next-gen sequencing might resolve their debates.
By Dan Cossins | August 1, 2013
In 2010, researchers analyzed DNA from the ancient Egyptian boy-king Tutankhamen and 10 of his relatives (JAMA, 303:638-47). It was a blockbuster study. Revealing family relationships among the 3,300-year-old royals and identifying the malaria parasite Plasmodium falciparum in several of the corpses, the research grabbed headlines and was even the subject of a 3-part documentary aired by the Discovery Channel, which partly funded the project.
But the work drew criticism from some ancient-DNA experts, who claimed that the results could be explained by contamination from modern humans. The ensuing row deepened a long-standing rift among researchers who aim to coax genetic secrets from the mummified denizens of bygone civilizations. “For sure it is a highly debated field,” says Carsten Pusch of the University of Tübingen in Germany, who was part of the team that analyzed King Tut’s DNA. “The tone of the arguments is sometimes a little bit strong.”
On one side are “believers,” who claim to have analyzed DNA from dozens of Egyptian mummies. On the other side, skeptics view such claims as highly problematic. DNA breaks down more quickly in hot conditions, causing many to doubt whether fragments long enough to enable reliable analysis can survive for thousands of years baking in the Egyptian desert.

Egyptian mummies yield genetic secrets
Next-generation sequencing finds DNA preserved in hot climates.
by Jo Marchant
The ancient Egyptians could soon be getting their genomes sequenced as a matter of routine. That’s the view, at least, of the first researchers to use next-generation techniques to analyse DNA from Egyptian mummies.
In a preliminary study that the authors describe as “a first step”, they detected hints of one of the mummies’ ancestral origins, as well as pathogens and a range of plant materials presumably used in the embalming process. The researchers, led by Carsten Pusch, a geneticist at the University of Tübingen in Germany, published their findings last week in the Journal of Applied Genetics[1].
Previous studies of DNA from Egyptian mummies have used a technique called polymerase chain reaction (PCR) to amplify specific segments of DNA. But these studies have been controversial. The PCR method is susceptible to contamination with modern DNA, especially when amplifying genes from humans or bacteria that are likely to be present in the environment.
DNA degrades relatively quickly in warm conditions, leading to doubts that it would survive for long in the Egyptian desert. For example, a high-profile DNA analysis of 3,300-year-old royal mummies[2] published by Pusch and his colleagues in 2010 attracted scepticism. But the authors stood by their results, arguing that the embalming process must have preserved the DNA despite the heat.
