Papers -08-01-05 Possible 10th Planet Found (International Herald Tribune) "Astronomers announced Friday that they had found a lump of rock and ice that is larger than Pluto and the farthest known object in the solar system." "The discovery will probably rekindle debate over the definition of what is a planet and whether Pluto still merits the designation. The new object - as yet unnamed, but temporarily known as 2003 UB313 - is now 9 billion miles, or almost 14.5 billion kilometers, away from the Sun, or 97 times as far away as the Earth and about three times Pluto's current distance from the Sun. Its 560-year elliptical orbit brings it as close as 3.3 billion miles. Pluto's orbit ranges between 2.7 billion and 4.6 billion miles." 7-05 Astronomers Discuss Changing Earth's Orbit (CNN) Describes a plan, which must be put into place within 3.5 billion years, to move the Earth's orbit gradually away from the sun as the Sun becomes hotter. Talk about planning ahead... 2-01 Human Cloning Advanced for Treating Disease (BBC News) "South Korean scientists have cloned 30 human embryos to obtain cells they hope could one day be used to treat disease." "The resulting embryos were then grown up to produce so-called stem cells that can divide into any tissue in the body." "The aim is to use the cells to replace ones that have failed in patients with problems such as Alzheimer's disease." 2-4. Senate Leader Supports Stem Cell Research (ABC News) "In exclusive interview with 'GMA,' Senate Majority Leader Bill Frist explained his decision to break with President Bush for the first time, and throw his support behind a bill that would expand federal funding for embryonic stem cell research." "Frist said only embryos that would otherwise be discarded should be used for the research. Those that could be adopted or implanted would not be used." "Frist is not the first Republican to support stem cell research. Republican Sen. Arlen Spector of Pennsylvania, who suffers from advanced stage Hodgkins lymphoma, supports the research, as does former first lady Nancy Reagan." 7-05 Study: Global Warming Makes Hurricanes Stronger (ABC News) "Is global warming making hurricanes more ferocious? New research suggests the answer is yes. Scientists call the findings both surprising and "alarming" because they suggest global warming is influencing storms now rather than in the distant future." "The analysis by climatologist Kerry Emanuel of the Massachusetts Institute of Technology shows for the first time that major storms spinning in both the Atlantic and the Pacific since the 1970s have increased in duration and intensity by about 50 percent." "These trends are closely linked to increases in the average temperatures of the ocean surface and also correspond to increases in global average atmospheric temperatures during the same period." 7-05 X-Ray Technology to Improve View of Universe (BBC News) "The researchers have successfully tested a small prototype which if scaled up could be a million times more powerful than today's observatories." "Professor Cash said a fully scaled-up version of the design could resolve a region the size of a dinner plate on the surface of the Sun." 8-04
