SHANGHAI--(BUSINESS WIRE)--Sep 8, 2023--

Scientists in Israel have created a model of a human embryo from stem cells, without using sperm, eggs or a womb. A team at Israel's Weizmann Institute of Science made the model, which resembles an embryo at day 14, when it acquires internal structures but before it lays down the foundations for body organs, and the work was published in the journal Nature. But the scientists involved said it would take a long time yet to create an embryo from scratch. Team leader Jacob Hanna said the team took stem cells derived from adult human skin cells, as well as others cultured in the lab, then reverted the cells to an early state.They then manipulated them to make a model of an embryo, rather than an actual or synthetic one. "The question is, when does an embryo model become considered an embryo? When that happens, we know the regulations. At the moment we are really, really far off from that point," Hanna said. However, they said the work could open the door to new ways to test the effect of drugs on pregnancies, better understand miscarriages and genetic diseases, and maybe grow transplant tissues and organs. "They are not identical. There are differences from human embryos, but still, this is the first time, if you open an atlas or a textbook, you can say - yeah I can really see the similarity between them," said Hanna. "In about 1 percent of the aggregates we can see that the cells start differentiating correctly, migrating and sorting themselves into the correct structure, and the farthest we could get is day 14 in human embryo development," he said. Their next goal, Hanna said, is to advance to day 21 and also reach a threshold of a 50 per cent success rate. Magdalena Żernicka-Goetz, a professor of development and stem cells at the University of Cambridge, said the study joins six other similar human embryo-like models published from teams around the world this year, including from her lab. "None of these models fully recapitulate natural human development but each adds to ways in which many aspects of human development can now be studied experimentally," she said.

The remains of 2,000-year-old Roman walls have been discovered by archaeologist in Switzerland in the foothills of the Alps. During the excavation of a gravel pit in Cham in the canton, or state, of Aug in central Switzerland, the walls, which once protected a Roman building complex, were found. Other pieces have also been unearthed by archaeologists, include a plaster wall, iron nails, and gold fragments. As well as items such as bowls, millstones for grinding, glassware, and crockery and ceramic jugs known as amphorae. In a statement form the Office for the Preservation of Monuments and Archeology, the findings were labelled an "archaeological sensation" for the region and could shed light on Roman activity in central Switzerland. Gishan Schaeren, head of the Department of Prehistory and Protohistoric Archaeology said in the statement: "Roman buildings of similar dimensions were last excavated in Cham-Heiligkreuz almost 100 years ago. We were also amazed that the top bricks were even visible above ground." The walls extend over an area of at least 5,300 square feet (500 square metres). Although it's unclear how Romans used the site, including whether it was a "villa with a view or a temple building," said professor of archaeology of the Roman provinces at the University of Bern Christa Ebnöther. The team said that findings of Roman tableware known as terra sigillata - which means "sealed earth" in Latin - were found, suggesting elite people were at the site. The amphorae, which typically held liquids such as wine, olive oil and fish sauce, are evidence that Romans in the region traded with those in the Mediterranean. Archaeologists also found several copper and bronze coins, including a silver denarius minted by Julius Caesar from the first century B.C. The discovery of the Roman walls is not the first ancient find in the area. Previously, archaeologists had found remains of a middle Bronze Age settlement, burials from the late Bronze Age, and a number of coins form the era of the Celts.

YouTube has launched a verification system for UK-based doctors, nurses, and other healthcare professionals to help Britons dodge medical misinformation online. UK-based users accounted for more than two billion video views of clips on health conditions in 2021. YouTube added a new seal of approval to accounts run by licensed doctors, nurses, psychologists, and other health practitioners or organisations who have passed stringent verification checks to fight misinformation. YouTube head of UK health Dr Vishaal Virani said the move to verified health videos for UK users was crucial due to the number of Brits accessing healthcare information through the video-sharing platform. Dr Virani told the BBC: “Whether we like it or not, whether we want it or not, whether the health industry is pushing for it or not, people are accessing health information online. We all know how difficult it can be to differentiate between healthcare information from trusted and reliable sources and content which is inaccurate or doubtful provenance Professor Dame Helen Stokes-Lampard “We need to do as good a job as possible to bring rigour to the content that they are subsequently consuming when they do start their care journey online.” The verification system began accepting applications from UK-based healthcare professionals to those with an active medical licence in June. Accounts that applied to the verification scheme are now starting to receive their YouTube mark of authenticity on their videos, to make it as easy as possible users to know if the information has come from a qualified healthcare professional. Potential health creators submitting their accounts have to go through a rigorous, multi-stepped verification process that works in partnership with the Academy of Medical Royal Colleges and the NHS. Health creators also have their past videos scrutinised and do not receive verification if previous videos uploaded to YouTube have contained any medical misinformation. Chairwoman of the Academy of Medical Royal Colleges Professor Dame Helen Stokes-Lampard said the partnership with YouTube had resulted in a positive solution for all. Dame Helen said in a statement: “We all know how difficult it can be to differentiate between healthcare information from trusted and reliable sources and content which is inaccurate or doubtful provenance. “I am pleased to say we have been able to draw on our own expertise and that of organisations from across the UK healthcare landscape to produce an easy-to-apply set of principles which will ultimately benefit everyone who turns to YouTube seeking trustworthy health information.” YouTuber and doctor Simi Adedeji has already received her YouTube tick of approval. But Dr Adedeji told the BBC that her videos, which primarily focus on skin health and women’s health, are not to be used in lieu of making an appointment with a medical professional for real-life advice. Dr Adedeji said: “There’s a difference between giving medical education, which is what we’re doing, and giving medical advice, which we don’t do. “It’s about giving medical information so that the audience feels empowered and can then go and see their doctor.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Should you swap your foundation for a lightweight skin tint?
