Who Owns the Moon? Within the next ten years, the U. S., China, Israel, and a crowd of private companies plan to set up camp on the moon. So if and when they plant a flag, does _ give them property rights? A NASA working group hosted a discussion this week to ask: Who owns the moon? The answer, of course, is no use. The Outer Space Treaty, the international signed by more than 100 countries, states that the moon and other celestial bodies   are the province of all mankind. No doubt that would annoy all of the people throughout the ages, like monks from the Middle Ages, who have tried to claim the moon was theirs. But ownership is different from property rights. People who rent apartments, for example, don't own where they live, but they still hold rights. So with all of the upcoming missions   to visit the moon and beyond, space industry thought leaders are seriously asking themselves how to deal with a potential land rush. " This is a very relevant discussion right now. We've got this wave of new lunar missions from around the world," said William Marshall, a scientist in the small-spacecraft office at NASA, but who spoke this week at an event hosted by NASA's Co Lab, a collaborative  public-private working group. He was speaking from his personal interest and not on behalf of the agency. To be sure, the United States aims to send astronauts back to the moon by as early as 2015, in a mission that would include a long-term settlement. China and Israel, among others, are also working on lunar projects. And for the first time, several private groups are building spacecraft to land on the moon in an attempt to win millions of dollars in the Google Lunar X Prize. Some participants say that they plan to gain some property rights in the mission. " The Google Lunar X Prize" aims to   _  . A) encourage private groups to land on the moon B) help NASA host a discussion about land rush on the moon C) help some developing countries to complete their lunar projects D) reward some countries or private groups which haven't stepped on the moon

Q: Health officials issued a waring over common energy-saving lghtbulbs  after research showed some types could potentially harm the skin and may even raise the risk of cancer. A study by the Health Protection Agency (HPA) found that some eco-friendly lightbuulbs release levels of ultraviolet (UV)   radiation that are above recognized safety limits. The agency urged people who work with lamps nearby to avoid spending more than one hour within a foot of the eco-friendly bulbs. The warning was directed at those using desk lamps for long periods, such as jewellery makers, and others who might have lights close to their faces, such as car mechanics. John O'Hagan, a scientist at the HPA's centre for radiation, chemical and environmental dangers, began tests on the ligthbulbs after patient groups raised concern about them. Among the groups were patients with a skin disease called lupus, which makes people highly sensitive to light. The tests measured UV light from the lamps and found the highest levels of UV radiation, measured 2cm from the lightbulbs, were _ to being outside in direct sunlight in the summer. The most immediate risk from the lightbulbs is a reddening of the skin similar to sunburn, but there is also a small increased risk of skin cancer associated with this, again similar to that of sunburn. The risk of health problems from the lightbulbs was not so high that people should remove them from their homes. People are advised to avoid using open lightbulbs for long close work until the problem is sorted out. It has confirmed that the government will not be reviewing its strategy on introducing energy efficient lightbulbs. In order not to be harmed by the UV radiation from some lightbulbs, people should   _  . A) stop using eco-friendly lightbulbs at home B) avoid using open lightbulbs for long close work C) take care not to expose their skin to direct sunlight D) urge the government to ban the use of lightbulbs
