[EX Q]: Article: Millions of people will be able to track each and every move by friends and family through their mobile phones,thanks to a new feature launched by Google yesterday. The new system named "Latitude" uses a map to show exactly where a loved one is at any time, sometimes discovering their location to a few meters.Worried parents will be able to check up on where their children have got to after school, friends can meet for a quick drink if they see they are nearby and wives will be able to see if their husbands really are working late at the office. The feature was made available immediately on millions of mobile phones that can access the web,such as the BlackBerry.Within weeks Google hopes to launch a new one that wilt also work on computers as well. "Once you've shared your location,you can hide it from all of your friends at once,or you can turn off Google Latitude completely at any time." said a Google spokesman."You can adjust your privacy settings in Latitude so that you share as much or as little about your location as you want,with whom you want." Google said that the company had tested the product with thousands of people to make sure that it was safe for the customers,but experts were not so sure.Simon Davies,director of Privacy International,said Latitude would open up a "privacy minefield ". "It's about the little white lies.You might be avoiding going to work, and now your boss might be able to see that you're at Twickenham instead of at home."said Ian Angell, an information expert at the London School of Economics."You've already got mobile phone technology where husbands and wives track each other in secret.Now Google is so widely used that it will only worsen the situation."

[EX Q]: Article: Alaska's Arctic lakes now freeze later and melt earlier in the year than in 1950,leaving them easy to suffer water loss from evaporation and possibly adding to local warming,a new study finds.The winter ice season near Barrow,Alaska,is shorter than in 1950,researchers reported Jan.30 in the journal The Cryosphere. Lake ice is also thinner each winter.The scientists surveyed 402 lakes on the North Slope,where permafrost (permanently frozen ground)and shallow lakes dominate the areA. In 2011,the lake ice was 38 percent thinner than in 1950,and 22 percent fewer lakes froze through to their bottoms. "When we saw the actual numbers we were shocked at how dramatic the change has been,"lead study author Cristina Surdu,of the University of Waterloo in Canada,said in a statement.Surdu and her co-authors analyzed the changes in lake--ice thickness and ice cover with satellite images and climate model simulations(satellite images are only available from 1991). The climate models suggest the Arctic lakes froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared with the winter of 1950."The changes in ice and the shortened winter affect Northern communities that depend on ice roads to transport goods,"Surdu saiD. For example,every winter,oil companies build roads over frozen lakes to carry supplies to Prudhoe Bay. "The dramatic changes in lake ice may also contribute to further warming of the entire region,because open water on lakes contributes to warmer air temperatures,"Surdu saiD. The Arctic is warming twice as fast as the rest of the planet,for reasons that may include its layered atmosphere,which traps heat,and the loss of sea ice and snow cover,which help reflect the sun's energy when present.
