Police in San Francisco closed off part of the city's famous Fisherman's Wharf on suspicion a juggler was using a live hand grenade in his act. Bomb squad investigators determined the grenade was a replica, but not until after police had shut down an entire block, reports the San Francisco Chronicle. "You have to take all precautions because you never know," said a police spokesman. "If you're a juggler, and you're juggling something that looks like it could be dangerous, please have a big sign saying it's fake," he said. "Or just use bananas." The performer, who has not been identified, was arrested and may face charges. Girl's hand grafted on to her leg - Surgeons in China saved a little girl's hand, by grafting it on to her leg for three months. Nine-year-old Ming Li lost her hand when she was run over by a tractor on her way to school in July. But her arm was too badly damaged to reattach it to her wrist so doctors temporarily attached it to her right calf instead. Dr Hou Jianxi, spokesman for the hospital in Zhengzhou, Henan Province, said the hand had now been transplanted back on to her arm. "When she came in, her left hand was completely severed from her body. It was very scary," he told the Zhoukou Evening Post. "But Ming Li can now move her wrist again and her left hand is a healthy pink colour proving that the blood is circulating well." Li will need two more operations over the next year. One to improve her hand functions and some plastic surgery to remove her scars. But Dr Hou said: "After surgery, and with plenty of physiotherapy, we are confident her left hand will be capable of doing most things. "We can't give a precise percentage of how much movement she will get back but she should be able to look after herself and even drive a car Cricket balls bowl over scientists - Scientists say a species of bushcricket has the biggest testicles of any creature on Earth - proportionately. The bushcricket's testicles account for up to 14% of its body weight - equivalent to a human with testicles weighing 5kg (11lbs) each. Karim Vahed of the University of Derby and his team began their studies by measuring the testicle size of 21 species of bushcrickets, reports the BBC. They found that one species - Platycleis affinis - far surpassed the previous record for the proportionally largest testicles. The previous holder was a species of fruit fly - Drosophila bifurca - whose testicles to body weight ratio has been recorded as 10.6%. However, a study of the bushcricket's mating strategies revealed they released only small amounts of sperm at each mating. That suggests the big testes are for mating with many females, not producing competitive volumes of sperm for each encounter. "Males with bigger testicles are actually producing smaller amounts," Dr Vahed told BBC News. "This very much favours the alternative hypothesis: that it's about the number of different females the male can fertilise, rather than getting a greater success per female." |
