　　Sri Lankan wildlife officials have said the giant waves that killed over 24,000 people along the Indian ocean island's coast clearly 3 wild beasts, with no dead animals found.

　　"No elephants are dead, not 4 a dead rabbit. I think animals can 5 disaster. They have a sixth sense. They know when things are happening," H. D. Ratnayake, deputy director of Sri Lanka's wildlife Department, said about one month after the tsunami attack. The 6 washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka's biggest wildlife 7 and home to hundreds of wild elephants and several leopards.

　　"There has been a lot of 8 evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said matthew van Lierop, an animal behavior 9 at Johannesburg zoo.

　　"There have been no 10 studies because you can't really test it in a lab or field setting2," he told Reuters. other authorities concurred with this 11 .

　　"wildlife seem to be able to pick up certain 12 , especially birds... there are many reports of birds detecting impending disasters," said clive walker, who has written several books on African wildlife.

　　Animals 13 rely on the known senses such as smell or hearing to avoid danger such as predators.

　　The notion of an animal "sixth sense" — or 14 other mythical power — is an enduring one3 which the evidence on Sri Lanka's ravaged coast is likely to add to.

　　The Romans saw owls 15 omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.

　　Singing Alarms could Save the Blind (c)

　　If you cannot see, you may not be able to1 find your way out of a burning building — and that could be fatal. Apany in Leeds could change all that2 1 directional sound alarms capable of guiding you to the exit.

　　Sound Alert, apany 2 the university of Leeds, is installing the alarms in a residential home for 3 people in Sommerset and a resource centre for the blind in cumbria. 4 produce a wide range of frequencies that enable the brain to determine where the 5 ising from.

　　Deborah withington of Sound Alert says that the alarms use most of the frequencies that can be 6 by humans. "It is a burst of white noise 7 people say sounds like static on the radio," she says. "Its life-saving potential is great."

　　She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of3 a large 8 room. It 9 them nearly four minutes to find the door 10 a sound alarm, but only 15 seconds with one.

　　withington studies how the brain 11 sounds at the university. She says that the 12 of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms 13 the same concept have already been installed on emergency vehicles.

　　The alarms will also include rising or falling frequencies to indicate whether people should go up 14 down stairs. They were 15 with the aid of a large grant from British Nuclear Fuels.

　　Less Is more (B)

　　It sounds all wrong — drilling holes in a piece of wood to make it more resistant to knocks. But it works because the energy from the blow gets distributed throughout the wood rather than focusing on one weak spot. The discovery should lead to more effective and lighter packaging materials.

　　carpenters have known 1 centuries that some woods are tougher than others. Hickory, for example, was turned into axe handles and cartwheel spokes because it can absorb shocks without breaking. white oak, for example, is much more easily damaged, 2 it is almost as dense.1 Julian Vincent at Bathe university and his team were convinced the wood's internal structure could explain the differences.

　　many trees have tubular vessels that run 3 the trunk and carry water to the leaves. In oak they are large, and arranged in narrow bands, but in hickory they are smaller, and more evenly distributed. The researchers 4 this layout might distribute a blow's energy throughout the wood, soaking up a bigger hit. To test the idea, they drilled holes 0.65 millimetres across into a block of spruce, a wood with 5 vessels, and found that 6 withstood a harder knock. 7 when there were more than about 30 holes per square centimetre did the wood's performance drop off.

　　A uniform substance doesn't cope well with knocks because only a small proportion of the material is actually 8 . All the energy from the blow goes towards breaking the material in one or two places, but often the pieces left 9 are pristine.

　　But instead of the energy being concentrated in one place, the holes provide many weak spots that all absorb energy as they break, says Vincent. "You are controlling the places 10 the wood breaks, and it can then absorb more 11 , more safely."

　　The researchers believe the principle could be applied to any material — 12 example, to manufacture lighter and more protective packaging. It could 13 be used in car bumpers, crash barriers and armour for military vehicles, says ulrike wegst, 14 the max Plank Institute for mental Research in Stuttgart. But she emphasizes that you'd 15 to design the substance with the direction of force in mind. "The direction of loading is crucial," she says.
