☆ Reconstruction reveals face of Neanderthal specimen Shanidar Z
▼ + stars: | 2024-05-01 | by ( Katie Hunt | ) edition.cnn.com time to read: +7 min

Known as Shanidar Z, after the cave in Iraqi Kurdistan where she was found in 2018, the woman was a Neanderthal, a type of ancient human that disappeared around 40,000 years ago. The Shanidar Z facial reconstruction suggests that these differences might not have been so stark in life, Pomeroy said. Shanidar cave in Iraqi Kurdistan was first excavated in the 1950s. Neanderthals may not have honored their dead with bouquets of flowers, but the inhabitants of Shanidar Cave were likely an empathetic species, research suggests. Shanidar Z is the first Neanderthal found in the cave in more than 50 years, Pomeroy said, but the site could still yield more discoveries.

☆ Webb space telescope spots oldest ‘dead’ galaxy

CNN —Astronomers have spotted the oldest “dead” galaxy ever observed while studying the cosmos with the James Webb Space Telescope, and it’s one of the deepest views into the distant universe made with the observatory to date. The galaxy existed when the universe was only about 700 million years into its current age of about 13.8 billion years. But something made the galaxy suddenly halt star formation almost as quickly as star birth had begun more than 13 billion years ago, and the researchers have yet to uncover the cause. Studying the galaxy could reveal new insights about the early universe and the factors that affect star formation within galaxies, according to the authors. “Until now, to understand the early universe, we’ve used models based on the modern universe.

☆ Ancient DNA reveals genetic roots of multiple sclerosis and other diseases

These genetic variants may have subsequently proved beneficial to European populations in making the shift from hunting and gathering to farming. “DNA from hunter-gatherers is present at higher levels in Northeastern Europe, which means the region has an elevated genetic risk of developing Alzheimer’s disease,” Barrie said. Similarly, the ancient genetic information shed light on the evolutionary history of traits such as height and lactose tolerance. And for most traits, MS included, the genetic effects are the result of multiple genetic variants,” he said. “Ultimately, we can’t say that MS came from Bronze Age populations, but these populations’ movements and environments contribute to differences in MS risk today.”

London CNN —Oxford was the murder capital of late-medieval England, with the city’s male university population being the main catalyst for violence, according to new research. “It wasn’t surprising, it was what I expected,” Professor Manuel Eisner, lead murder map investigator and director of the University of Cambridge’s Institute of Criminology, told CNN. Medieval map of Oxford, England circa 12th or 13th century Universal History Archive/Universal Images Group/Getty ImagesCollectively, the project has cataloged 354 homicide crime scenes in 14th-century England. Oxford students at the time were all male and typically aged between 14 and 21 years old. “What it meant for Oxford is lots of young men, and young men can cause problems,” Eisner said, adding that these young men would not have had much social control, but would have had access to alcohol and weapons.

☆ Fact Check-Sahara dust magnetism is not evidence of chemtrails

The social media post for the clip, as well as another video posted to Twitter here, also claims that the dust’s magnetism is evidence of “chemtrails". However, experts say magnetism is typical of Saharan dust. Saharan dust’s characteristic red colour reflects the presence of small amounts of haematite, a weakly-magnetic mineral, she said. However, air pollution-derived metals are usually present in much lower quantities than the naturally-sourced metal-bearing dust particles, she said. Saharan dust contains naturally magnetic particles, including haematite, which gives the dust its characteristic red colour.

☆ Face of seventh-century teen buried with rare cross revealed

She was ceremoniously laid to rest with a gold and garnet-encrusted cross, and her burial site was uncovered more than a decade ago. The remains of the teen, who died around the age of 16, according to researchers, presented striking questions: Where did she come from? The Trumpington Cross was found during an excavation of the grave in 2012. And her ornately decorated cross, often referred to as the Trumpington Cross, indicates she was likely an aristocrat, if not royalty, and one of the era’s earliest Christian converts. The Trumpington Cross that was found at the burial site, believed to have been unearthed for the first time since the seventh century.

☆ Ancient toilets unearthed in Jerusalem reveal a debilitating and sometimes fatal disease

CNN —The Iron Age users of two ancient toilets in Jerusalem were not a healthy bunch, according to an analysis of poop samples from the 2,500-year-old latrines. Ancient poop contains a trove of fascinating informationA stone toilet seat was excavated in 2019 south of Jerusalem in the neighborhood of Armon ha-Natziv. Archaeologists excavating the latrines took samples from sediment in the cesspit beneath each toilet seat. They found one seat south of Jerusalem in the neighborhood of Armon ha-Natziv at a mansion excavated in 2019. Cities such as Jerusalem likely would have been hot spots for disease outbreaks, and illnesses would have spread easily by traders and during military expeditions, according to the study.

Researchers for decades have attempted to recreate nuclear fusion – replicating the fusion that powers the sun. Nuclear fusion happens when two or more atoms are fused into one larger one, a process that generates a massive amount of energy as heat. Scientists across the globe have been inching toward the breakthrough, using different methods to try to achieve the same goal. This heat can then be used to warm water, create steam and power turbines to generate power. “The opposing argument is that this result is miles away from actual energy gain required for the production of electricity,” he said.
