Dark matter isn’t interacting with itself after all

Hints that a galactic collision knocked the invisible mass askew are disproven. Dark matter is still the shyest particle in physics. New observations show that dark matter in galaxy cluster Abell 3827 stubbornly ignores all other kinds of matter — including itself, astronomers reported April 6 at the European Week of Astronomy and Space Science in Liverpool, England. The research, also posted online at arXiv.org, negates an earlier finding that stars were separated from their dark matter in Abell 3827, a cluster including four colliding galaxies about 1.3 billion light-years from Earth (SN: 5/16/15, p. 10). At the time,...

Why AI isn’t going to solve Facebook’s fake news problem

Moderation will always be a problem on a platform this huge. Facebook has a lot of problems right now, but one that’s definitely not going away any time soon is fake news. As the company’s user base has grown to include more than a quarter of the world’s population, it has (understandably) struggled to control what they all post and share. For Facebook, unwanted content can be anything from mild nudity to serious violence, but what’s proved to be most sensitive and damaging for the company is hoaxes and misinformation — especially when it has a political bent. So...

Conservationists use astronomy software to save species

Researchers are using astronomical techniques used to study distant stars to survey endangered species. The team of scientists is developing a system to automatically identify animals using a camera that has been mounted on a drone. It is able to identify them from the heat they give off, even when vegetation is in the way. Details of the system were presented at the annual meeting of the European Astronomical Society in Liverpool, UK. The idea was developed by Serge Wich, a conservationist at Liverpool John Moores University, and Dr Steve Longmore, an astrophysicist at the same university. He says...

‘Send in the drones’ to protect soil

Squadrons of drones should be deployed to locate and penalise farmers who let soil run off their fields, a report will say. A coalition of campaigners complains that the Environment Agency can only check soil on 0.5% of farms each year. Their report says drones can help to spot bad farming, which is said to cost more than £1.2bn a year by clogging rivers and contributing to floods. The government said it was considering the ideas for combating soil run-off The proposals come from the Angling Trust, WWF and the Rivers Trust – with support from the RSPB. Their...
