Scientists monitoring the Petermann glacier say that only this week a chunk measuring 1.1 square miles broke off. But cracks in the ice indicate that, within the next couple of weeks, a piece of ice weighing 5 billion tonnes and measuring 38 square miles is expected detach itself from the glacier. Scientists say this is due to warm ocean currents fuelled by global warming. DiD Venus once have oceans and plate tectonics just like Earth? Europes Venus Express orbiter has returned data suggesting the planets surface is made up of granite, which on Earth requires water and tectonic plate movement to form. Venus and Earth started out as twin planets of nearly equal size and composition. But at some point Venus became an inhospitable place. SUFFeReRS of severe obsessive compulsive disorder could be treated with an implantable brain stimulator, after the new device was approved by european regulators.

The week in numbers Big deal: the worlds largest telescope, in the Canaries Science&technology FORTY years ago today the Apollo 11 mission blasted off with three intrepid explorers on board, two of whom made history four days later by becoming the first people to set foot on the moon. So to celebrate the anniversary of the lunar landing, DUNCAN GRAHAM- ROWE offers a glimpse of how you can get in on the action with our pick of space-related gadgets and even a zero-gravity trip... ScarabBeetleRobotKit WHILE US space agency Nasa still battles to free its Mars Rover from a sandy bunker its easy to speculate about how easy it would have been to design it better. The Scarab Beetle Robot Kit, with its alien rover-like design, will give you a taste of how difficult it is. Build the robot and then watch as it tries to learn how to avoid obstacles using its sensors. About 22, livesciencestore.com SpaceFood IF YOUR taste for space is more gastronomic than gravitational, its now possible to try space food for yourself. These tasty treats are the same as those developed for the original Apollo programme and consist of food that has been frozen to - 40C then vacuum- dried and sealed in foil pouches. Available in ice cream flavours they are devoid of moisture and quite crunchy. 9.95 for pack of three flavours, firebox.com 10.4metres is the width of the worlds largest and most advanced telescope set 7,874 feet above sea level on La Palma in the Canaries. Its 36 hexagonal reflectors are the smoothest surfaces ever made. 70per cent of all antibiotics in the US are used on livestock to promote growth, prompting the US Food & Drug Administration to push for the use of such drugs in animals only in cases where they can cure or prevent disease. 86per cent of cars could be electric by 2030, provided consumers dont pay for the batteries themselves, suggests a new study. By using battery replacement services rather than recharging stations, the cost of using electric cars should come down to below that of petrol cars. 9per cent of Nigerians suffer from cyanide poisoning caused by eating the cassava plant -- and research suggests rising CO2 levels will cause the plant to make more cyanide. half a billion people depend upon cassava, which can be eaten safely when made into flour. But many still eat the leaves and roots raw. 91,440metres is how high the crew eject system will operate on Nasas Orion spacecraft designed to replace the Space Shuttle.
