the dawn of a new space age

THE plan looks ambitious, perhaps overambitious. But then they said that in 1961, when President John F. Kennedy announced that the US would put a human on the moon by the decade’s end. And the lunar lander that Amazon boss Jeff Bezos hopes will return humans to the moon by 2024 (see page 7) is just one tune in a cacophony of new space exploration initiatives. New Scientist’s story is entwined with that of space exploration: we launched in November 1956, less than a year before Sputnik 1, the Soviet satellite that kicked off the cold-war space race. Now the 50th anniversary of the successful Apollo 11 moon landing – the end product of Kennedy’s ambition – is near. To mark it, we will have a special series of articles on…

crewed missions to the moon

NASA and Jeff Bezos’s company Blue Origin both want to land humans on the moon in five years’ time. Separate announcements from each organisation have come in the past week, but could they end up working together? Blue Origin was first to hit the headlines by revealing a mock-up of Blue Moon (pictured), a lunar lander that the firm hopes will return humans to the moon’s surface by 2024. “It’s time to go back to the moon, this time to stay,” Bezos said at the unveiling on 9 May. The lander is designed to launch on Blue Origin’s New Glenn rocket, which is currently in development. Blue Moon should be able to land up to 6.5 tonnes on the lunar surface. It will be able to carry rovers, vehicles that can launch…

free-floating dna to reveal the health of river and lake ecosystems

THE mix of DNA floating in rivers and lakes will finally be used to monitor the state of aquatic ecosystems, after years of tests to show that the technique works. Conventionally, aquatic life is monitored by capturing organisms, either by using nets or scraping under boulders, for examination. These techniques are time-consuming, can harm species and require skilled ecologists. Monitoring fish typically involves using electricity to stun them, which can sometimes prove fatal. But these techniques could be replaced by simply taking a water sample and analysing the DNA in it. This environmental DNA (eDNA) comes from the cells, waste and blood of organisms. Thanks to advances in cheap, fast genetic sequencing and in our ability to identify which species the DNA comes from, England’s Environment Agency plans to start using eDNA to…

can we make our plastics from captured carbon?

THE really hard part of reducing greenhouse gas emissions could be even more difficult than we thought. Most chemicals we use, including plastics, contain carbon, which is currently taken from fossil fuels. In theory, the global chemicals industry could switch to using carbon dioxide captured from the air as a feedstock. But a study suggests that this would require vast amounts of clean electricity. There has been a lot of talk about greening the chemicals industry, says André Bardow of RWTH Aachen University in Germany, but no one has worked out what it would take to do it. So he and his team created a bottom-up model of the industry, looking at what is needed to create the key feedstocks. They calculated that using carbon captured from the air for this could remove…

kidney-for-liver swap

“IT WAS heartbreaking for me to see what my mom was going through – dialysis was getting to be really painful for her,” says Aliana Deveza from Santa Cruz, California. “I had to help.” Her mother, Erosalyn Deveza, was on the waiting list for a kidney transplant. Aliana wanted to give one of her own kidneys to her mother, but she was turned down because she might develop the same health problems in later life. So Aliana came up with a different plan. In 2017, she instigated the world’s first paired exchange of different organs between living donors, swapping half her liver for someone else’s kidney. A case study of the organ swap has now been published (American Journal of Transplantation, doi.org/c5nz), and the surgeons involved are calling for more exchanges like…
