...Endangered Species Act, habitat-protecting nature reserves and hunting prohibitions are all designed to slow the rate of extinction and preserve dwindling species. But a new paper in the journal Biological Conservation says we may not be trying hard enough. A team of Australian researchers led by environmental scientist Lochran Traill finds that current conservation policy tends to underestimate the number of individuals needed in a population of endangered species to keep it viable. In the face of environmental fluctuation and potential disasters, says Traill, we need animal populations to number in the thousands for survival - not in the hundreds...
...excuse for the slow pace of reform. "The idea is to delay the reforms based on the idea that society wouldn't accept drastic changes," says Mohammad al-Qahtani, a reform advocate and professor at the Saudi Foreign Ministry's diplomatic training institute. Awadh al-Badi, a political scientist at the King Faisal Center for Research and Islamic Studies, says the reason that King Abdullah and the royal family are still cautious on women's rights is that they themselves are products of Saudi culture. "It's a generational thing," al-Badi says. "The King is an 85-year...
...balloon was climbing higher over Larimer County, Colorado, and on the ground a 10-year-old boy named Bradford Heene had told the sheriff that his little brother Falcon was inside. Falcon? Was some Greek narrative poet scripting this tragedy? Their father Richard longed to live large, a scientist, storm chaser, wife swapper, aspiring reality-TV star. He had built the vessel in the backyard; they called it his "flying saucer...
...Infections and eating problems were hallmark for patients [with advanced dementia],” said Mitchell, who is also a senior scientist at Hebrew SeniorLife (HSL), a Harvard Medical School affiliate. “Far too many patients received stressing symptoms, and the care they receive at the end of life has not been optimal, in part because they have not been recognized as [having] a terminal illness...
...fitting coincidence, the first known manned balloon flight occurred 226 years to the day before Falcon's supposed flight. On Oct. 15, 1783, French scientist Jean-François Pilâtre de Rozier ascended 84 ft. (25 m) off the ground - the length of the rope attached to the vessel. He followed this tentative milestone with the first untethered flight on Nov. 21, reaching an altitude of 3,000 ft. (900 m). But de Rozier would also have the inglorious distinction of becoming ballooning's first fatality. During a 1785 attempt to cross the English Channel, de Rozier...
