'Creepy' Fungi have been contaminating international space stations
'Creepy' Fungi have been contaminating international space stations
Astronauts have never truly been alone. In 1988, on board the Russian space station Mir, the crew noticed something had blanketed one of their windows – from the outside. Whatever it was had even begun to infiltrate its way into the station, slowly destroying the window's titanium-quartz surface. The blanket was eventually revealed to be fungi that had managed to hitch a ride into space by clinging onto the astronauts themselves, Space.com reports. Amazingly, the fungi had managed to adapt to the space environment, surviving and thriving on windows, control panels, and air conditioners. The on board the space station even had their food and water contaminated. Although this was the first instance of a hijacker damaging the space station, it wasn't the last. Many space-borne fungi remain dormant during launch, until "activating" and reproducing to form thick, living mats on various regions in the space station. The fungi can threaten the health of those on board as well as damage electronics and plumbing. Since the 1988 incident, there have been numerous attempts to establish robust cleaning routines for scrubbing the fungi off walls and equipment, in an attempt to prevent the organisms from causing serious issues. Despite the concern surrounding the risks, scientists are trying to take advantage of the fungi's abilities. One team associated with the European Space Agency (ESA) recently conducted hypergravity experiments on fungi to better understand how these organisms survive effortlessly in the harsh environment of space. If these mechanisms are understood, fungi may be able to be used to build off-world settlements and be incorporated into off-world medications. In 2016, researchers at NASA's Jet Propulsion Laboratory in California launched fungi into space for the first time on board the International Space Station. The team studied how the ISS environment caused the species to create certain molecules it doesn't produce on Earth. "We are never going to be able to get rid of fungi entirely as we venture into space, so we need to understand them," André Antunes, a researcher who is part of the recent ESA study, said in a statement published on Monday. In addition, they offer positive opportunities as well as risks. Down on Earth fungi are employed to make food - such as yeast for fermentation - as well as medicines, chemical enzymes for industry as well as metal nanoparticles used in numerous fields.

Scientists grow human kidneys inside a pig for the first time
Scientists grow human kidneys inside a pig for the first time
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 could use lunar dust to make roads on the moon
Scientists could use lunar dust to make roads on the moon
Scientists have come up with a potential solution to deal with dust on the moon which makes conducting research tricky. Dust erodes space suits, clogs machinery, interferes with scientific instruments and makes moving around on the surface difficult. But they reckon moon dust could be melted using a giant lens developed by the European Space Agency to create solid roads and landing areas. Using a fine-grained material called EAC-1A, developed as a substitute for lunar soil, scientists used a 50mm diameter laser beam to heat the dust to about 1,600C and melt it. Then they traced out bendy triangle shapes, which could be interlocked to create solid surfaces across large areas of lunar soil to be used as road. However it would take about 100 days to create a 10 x 10m landing spot so it is not a quick fix. To make matters worse, the lens needed for the laser to work would be difficult to transport from Earth and could also get dust in it which may reduce its functionality. “You might think: ‘Streets on the moon, who needs that?’” said Prof Jens Günster, of the Federal Institute of Materials Research and Testing in Berlin and co-author of a report on the possible solution. “But in fact it’s a kind of depressing demand [even] early on. It’s very loose material, there’s no atmosphere, gravity is weak, so the dust gets everywhere. It contaminates not only your equipment but other nations’. No one would be happy to be covered in dust from another rocket." Dust has blighted previous missions, such as the Surveyor 3 spacecraft (damaged by dust kicked up by the Apollo 12 landing), and overcoming this challenge is a priority for Nasa, which aims to establish a permanent lunar outpost. Transporting building materials to the moon would be too expensive, so there is a need for unconventional solutions. “You need to use what’s there and that’s simply loose dust,” said Günster. The findings are published in the journal Scientific Reports. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
