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.

Former WWE superstar Steph De Lander, who wrestled for the company under the name of Persia Pirotta, claimed that she was once asked to perform at an impromptu show requested by Ron DeSantis. WWE's developmental class, the Performance Center, is based in Florida where DeSantis, who is currently campaigning to become the Republican presidential candidate for the 2024 election, just happens to be governor. During an interview with Vice Australia and New Zealand, De Lander said that she and a few other wrestlers were called in on a Saturday because DeSantis had asked for a wrestling show for his family.

We got called in on Saturday that Ron DeSantis wanted to have a wrestling show for his kids. "So him and his family came in, and they sat front row, and we all beat each other up on a Saturday morning because he wanted to take his kids to see the wrestling. "It is funny. If he becomes president, then I’ve technically wrestled in front of the president." 26-year-old DeLander competed for WWE under their NXT brand but was released in April 2022. The Australian has since gone on to wrestle for AEW, MLW, Impact, GCW and recently made her debut for DDT in Japan. In terms of Republicans, WWE is often more associated with DeSantis's opponent Donald Trump, who frequently appeared on WWE television prior to his political career and was inducted into the company's Hall of Fame in 2013. Meanwhile, DeSantis, despite the backing of Elon Musk, is struggling to gain momentum in the Republican race with Trump often gaining the upper hand thanks to his timely putdowns.
