Born survivor: the humble cockroach MIND OVER MATTER IS THE KEY A WHOLE new generation of games is about to hit the shops, with some already claiming to be the must have toy of the year. So, whats so special about these new gadgets? Well, they can read your mind... Okay, we might be going over the top a little bit there but they do read your brain waves and use them to move and play. Based on the same technology used in medicine to confirm a diagnosis of epilepsy and monitor brain function -- electroencephalography (EEG) -- the devices feature headsets with built-in electrodes that rest on your scalp. This lower-level EEG device uses dry electrodes to detect electrical activity in your brain and interpret it into a signal that is used to control the game. There are thought to be five different types of brain waves but the toys gener- ally work by detecting two or three of them -- alpha, beta or theta waves. The idea is to change your brain waves by either concentrating hard or attempting to relax and keep calm. The toys can detect just how fiercely you are concentrating or how completely you are relaxing and use that information to drive the mechanism in the toy -- a motor or fan for example. As a result, higher concentration or deeper relaxation means the motor spins faster and your performance in the game is better. But be careful, as soon as you stop to think yes, Im winning, you lose your focus and your performance collapses. Here we round up the pioneering games that could change the way we play... BY ROB PINNIGER The week in numbers Lite bytes Science news in brief from around the world TO SOLVE our planets energy requirements we may need to look to the ocean, according to US Navy chemists who have found a way to process sea water into an oil-like substance. If refined, it could be used to make kerosene- based jet fuel, but at present it requires more energy to be used than it produces. WAS life on Earth given a kick-start by comets? The first evidence of a comet harbouring amino acids -- a crucial building block of life -- adds weight to this theory. Amino acids form when organic compounds and water are zapped by a large amount of energy, such as light. Previously, evidence suggested that the conditions in space were particularly ripe for this. Now Nasas Stardust mission has confirmed it by definitively identifying an amino acid called glycine on an icy comet. THE secret of the cockroachs indestructible nature may have something to do with its ability to hold its breath for as long as 40 minutes, according to New Scientist magazine. This trick allows them to preserve water that would have been lost through respiration, enabling them to survive longer in dry conditions. This means that in the face of global warming they could thrive. Tall: Obama with Vladimir Putin Thought Science&technology HEADSET detects the electrical activity of the brain, made up of the movement of millions of neurons, through your scalp. Unlockingthepowerofthemind BRAIN WAVES Theta, alpha and beta are the waves most associated with relaxation and concentration. Alpha waves are detectable when the brain is relaxed and beta when the brain is focused. Beta rays Alpha rays Theta rays MOTOR the signal from the headset is converted into an electrical current strong enough to drive a fan, blowing a ball into the air. Lose focus, the motor slows and the ball falls. 1is not just the number of children families in the Chinese city of Guangzhou are allowed, but now also the number of dogs they are permitted to own. Breeding dogs has long been viewed as a bourgeois pastime by Chinese authorities, but the new policy, which has got the burgeoning middle classes hot under the collar, has been introduced to clean up city streets ahead of the Asian Games next year. 60per cent of water used by Indian farms is now pumped from underground reserves, causing water tables to fall fast. This has prompted concerns from scientists that the subcontinent could be heading for a major famine. $10(6.10) is what it will cost you to plant a flag on your very own star. Hard- up astronomers are using the adopt-a-star scheme to raise funds for a planet-hunting programme. For your investment you get to choose one of 100,000 stars and plant a flag on it using Google Sky. 186centimetres (6ft 1in) is Barack Obamas height, making him a relatively tall US president. A new study looking back over the past 75 years shows American voters appear to prefer taller leaders during times of economic hardship. Abe Lincoln, at 193cm (6ft4in), was the tallest, 30cm taller than the shortest, James Madison, at 5ft4in. 150million-year-old footprints left by a pterosaur suggest that these flying reptiles may have landed in much the same way as modern birds. The prints, unearthed in Crayssac, France, show that although these creatures walked around on all fours, when they landed they used only their rear legs to touch down. index.html2.html3.html4.html5.html6.html7.html8.html9.html10.html11.html12.html13.html14.html15.html16.html17.html18.html19.html20.html21.html22.html23.html24.html25.html26.html27.html28.html29.html30.html31.html32.html33.html34.html35.html36.html37.html38.html39.html
