NHS calls for ban on small magnetic toys after dozens of children who swallowed them needed urgent surgery Ingesting more than one magnet can cause major damage in hours if not removed They fuse in intestines or bowels, squeezing tissue and cutting off blood supply At least 65 children have been admitted to hospital for … Read more
A reversal of the magnetic poles 42,000 years ago triggered catastrophic climate change and may have wiped out Neanderthals, a new study shows. Australian researchers have analysed the radiocarbon record from ancient trees in New Zealand that were alive when the magnetic poles flipped. The trees revealed spikes in atmospheric radiocarbon levels, caused by the collapse … Read more

When migrating birds get lost, they can ‘read’ the signature of the Earth’s magnetic field well enough to find their way once again, a study has revealed. Researchers from the UK exposed Eurasian reed warblers to a fake magnetic signature — thousands of miles from their usual path — to see how they would react. Despite … Read more

The Sun’s corona — the outermost layer which can reach temperatures in excess of one million degrees Celsius — is chemically very different to the rest of the star despite being physically connected. Astronomers have been unable to explain, and prove, this phenomenon for more than half a century, making it one of astronomy’s enduring … Read more
Boy has 123 magnetic beads stuck in his stomach after ‘eating the toy balls one after another while watching TV The child swallowed the tiny balls when he was home with his sister in China He was taken to hospital after telling his family he had eaten only one bead X-ray shows a huge bundle of the … Read more
The Moon’s once powerful magnetic field helped shield Earth and its developing atmosphere from powerful solar storms 4 billion years ago, a new study claims. Researchers led by James Green, NASA’s chief scientist, created computer models simulating the protective impact the Moon once had over Earth. The combined magnetic fields of both the Moon and … Read more
Girl, 10, needed life-saving surgery to remove 15 trendy ‘magnetic balls’ that fused together in her intestine – after falling asleep with them in her mouth Sadie Latham was rushed to A&E at Alder Hey Children’s Hospital, Liverpool X-ray revealed she had digested more than a dozen tiny magnetic balls Doctors were forced to remove … Read more
NASA is monitoring a ‘small but evolving dent’ in Earth’s magnetic field that could impact satellites and spacecraft. Stretching from South American and to southwest Africa is the South Atlantic Anomaly (SSA), which is a weakened spot in the field that allows charged particles from the sun to dip closer to the surface than usual. … Read more
