South Korean plans to develop Stuxnet-type weapons to damage North Korean nuclear facilities South Korea is to develop cyber-attack tools in an attempt to damage North Korean nuclear facilities. The country's defence ministry wants to develop weapons similar to Stuxnet, the software designed to attack Iranian nuclear enrichment plants. The South Korean military will carry out missions using the so
Devoted dog owners often claim that their pets understand them. A new study suggests they could be right. By placing dogs in an MRI scanner, researchers from Hungary found that the canine brain reacts to voices in the same way that the human brain does. Emotionally charged sounds, such as crying or laughter, also prompted similar responses, perhaps explaining why dogs are attuned to human emotions
North Korea's leaders are often thought of as ruthless, secretive autocrats but rarely as popular children's authors. However, between issuing instructions about prison camps and the development of nuclear weapons, Kim Jong-un's father and grandfather apparently found time to write stories for the young. "At last the left cyst burst, emitting fierce flames and the captain fell down, dejectedly dro
Brain scans show a complex string of numbers and letters in mathematical formulae can evoke the same sense of beauty as artistic masterpieces and music from the greatest composers. Mathematicians were shown "ugly" and "beautiful" equations while in a brain scanner at University College London. The same emotional brain centres used to appreciate art were being activated by "beautiful" maths. The re
Scientific director, Bengt Holst, insists the giraffe population must be kept "genetically sound" A bid to save a young giraffe from destruction at Copenhagen Zoo has failed, and the giraffe was put down on Sunday morning. Thousands of people had signed an online petition appealing for a change of heart over the two-year-old called Marius. The zoo said it had no choice because of its duty to avoid
The world's oldest-known living cancer dates back 11,000 years, according to UK scientists. It arose in a single dog and has survived in canines ever since, with the cancer cells passing between animals when they mate. A team led by the Wellcome Trust Sanger Institute near Cambridge decoded the DNA of the cancer. It revealed the "genetic identikit" of an ancient husky-like dog, which first develop
But apart from the odd event, like some recent solar flares, it has been very quiet. And this damp squib of a maximum follows a solar minimum - the period when the Sun's activity troughs - that was longer and lower than scientists expected. "It's completely taken me and many other solar scientists by surprise," says Dr Lucie Green, from University College London's Mullard Space Science Laboratory.
A permit to hunt and kill an endangered Black Rhino in Namibia has been sold at a US auction for $350,000 (£212,000). The Dallas Safari Club in Texas says the hunt will help protect the species by removing an old aggressive rhino, and funding future conservation. However, the auction has been fiercely criticised by conservationists, and has even drawn death threats. Namibia is home to about a thir
The Fukushima disaster led many countries to rethink their view on nuclear energy. Germany plans to abandon it altogether, but French President Francois Hollande also wants to cut nuclear output sharply - by a third in 20 years. It's a big ask in a country that now relies on nuclear for 75% of its electricity. If fully implemented, the pledge would force the closure of up to 20 of the country's 58
A shortage of honeybees means that European farmers are increasingly reliant on wild pollinators In more than half of European countries, there are not enough honeybees to pollinate crops, according to new research. Scientists believe that a boom in biofuels has sparked a massive increase in the need for pollination. The shortage is particularly acute in Britain which has only a quarter of the hon
Higher levels of maternal vitamin D during pregnancy have been linked to better muscle development in children, say researchers. The study on 678 children, published in Endocrine Research, external, showed vitamin D levels in the womb were linked to grip strength at the age of four. The team at the University of Southampton say the muscle boost could persist throughout life. Trials are taking plac
US scientists have performed a dramatic reversal of the ageing process in animal studies. They used a chemical to rejuvenate muscle in mice and said it was the equivalent of transforming a 60-year-old's muscle to that of a 20-year-old - but muscle strength did not improve. Their study, in the journal Cell, external, identified an entirely new mechanism of ageing and then reversed it. Other researc
