A new study into the Earth beneath our feet has discovered that an ancient ocean floor structure could be wrapped around the planet's core which could be taller that Mount Everest in some areas. A brand new high-resolution mapping of the core has uncovered things that scientists previously didn't know according to a study that was first published in April. The discovery found that a thin but dense layer sits at around 2,900 kilometers below the surface at the Core Mantle Boundary where rocks meet the molten outer core of the planet. Geologist Samantha Hansen from the University of Alabama is quoted in the study saying: "Seismic investigations, such as ours, provide the highest resolution imaging of the interior structure of our planet, and we are finding that this structure is vastly more complicated than once thought." She adds: "Our research provides important connections between shallow and deep Earth structure and the overall processes driving our planet.” Hansen and her team conducted the research from 15 different stations in Antarctica by using seismic waves created by Earthquakes to create a map of what the inside of the planet looks like. The team identified the unexpected energy within seconds of the boundary-reflected wave from the seismic data. The findings show that although the layer is very thin it does spread for many, many kilometers and has been called the ultra-low velocity zone (ULVZs) due to its strong wave speed reductions. Due to the properties of the ULVZs the experts believe that the layer could vary dramatically in height. Geophysicist Edward Garnero from Arizona State University adds: "The material's thickness varies from a few kilometers to [tens] of kilometers. This suggests we are seeing mountains on the core, in some places up to five times taller than Mt. Everest." These underground mountains could play a significant role in how heat escapes from the Earth's core and power magnetic fields and volcanic eruptions. The team's studies suggest that the layer could encase all of the core but further research will have to be carried out to determine if that is the case.

Scientists have grown human kidneys in pigs, for the very first time. Researchers at the Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences and Wuyi University created human-pig chimeric embryos containing a combination of human and pig cells. When they transferred into 13 surrogate pig mothers, they developed kidneys that contained mostly human cells at a rate of 50 to 60 per cent, giving hope for potential transplants in the future. “Rat organs have been produced in mice, and mouse organs have been produced in rats, but previous attempts to grow human organs in pigs have not succeeded,” said the senior author Liangxue Lai. “Our approach improves the integration of human cells into recipient tissues and allows us to grow human organs in pigs.” The kidneys were not entirely human as they included vasculature and nerves made mostly from pig cells, meaning they could not be used for transplantation in their current form, but it is still a pretty impressive step. And apart from the kidneys, the embryos were dominated by pig cells, with very few human cells in the brain or central nervous system. Making brains using human and pig cells is very controversial for ethical reasons, so there are tight regulations for this kind of research. Meanwhile, pig cells tend to outcompete human cells during development, so previous experiments have created embryos that are almost entirely pig. The latest work, published in Cell Stem Cell, overcame this by genetically engineering a single-cell pig embryo so that it lacked two genes needed for kidney development. This created a gap within the embryo that could be filled by human cells. “We found that if you create a niche in the pig embryo, then the human cells naturally go into these spaces,” said Prof Zhen Dai of Guangzhou Institutes of Biomedicine and Health, another senior author. The scientists said that being able to incubate a fully human kidney inside a pig would be likely to take many years. “We would probably need to engineer the pigs in a much more complex way and that also brings some additional challenges,” said Miguel Esteban, also of the Guangzhou institute and a senior author. A central challenge would be to allow human nerves and vasculature to develop within the target organ without nerve cells developing in the central nervous system that could lead to a humanised brain. “Even theoretically it’s not clear how you’d do that,” said Ilic.

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.
