...itself, Alaska also ranks No. 1, year after year, in money it sucks in from Washington. In 2005 (the most recent figures), according to the Tax Foundation, Alaska ranked 18th in federal taxes paid per resident ($5,434) but first in federal spending received per resident ($13,950). Its ratio of federal spending received to federal taxes paid ranks third among the 50 states, and in the absolute amount it receives from Washington over and above the amount it sends to Washington, Alaska ranks...
...nearly tripled between 2003 and 2007 to 69,000, but many of the new jobs were filled by foreign workers from China, Hong Kong and the Philippines. In 2003, approximately one out of every 10 jobs was filled by a foreigner. By the first quarter of this year, that ratio rose to one in four. Although many of the choicest positions are reserved by regulation for locals - all card dealers in casinos, for example, must be Macanese - the surge of imported staff has led to complaints that outsiders are reaping a disproportionate amount of the benefits of Macau's boom...
...found that in fish that do have temperature-dependent sex determination [TSD], a rise in water temperature of just 1.5 degrees Celsius can change the male-to-female ratio from 1:1 to 3:1," says Piferrer, the study's co-author. In especially sensitive fish, a greater increase can throw the balance even more out of whack. Ospina-Alvarez and Piferrer have found that in the South American pejerrey, for example, an increase of 4 degrees Celsius can result in a population that is 98% male...
...Beneath their fine, carbon-fiber exteriors, the two cars employ different methods of sucking power and speed out of batteries. Tesla's Energy Storage System utilizes several thousand lithium-ion cells, which, due to their high energy density, exceptional energy-to-weight ratio and capacity for hundreds of charge and discharge cycles, are increasingly one of the most popular types of battery. The Lightning, on the other hand, has benefited from the wonders of nanotechnology. Its 30 batteries are made of lithium-titanate nanoparticles, a development from the conventional lithium-ion cell; they boast a range of over 185 miles...
...sheer ubiquity of carbon is what makes eliminating greenhouse-gas emissions so difficult. But the surprising truth, Roston writes, is that we have actually been decarbonizing over time. Humanity's main fuel for eons was wood, which has a carbon-to-hydrogen ratio of 10 to 1 when burned; by comparison, that ratio is 2 to 1 for coal and 1 to 2 for oil. The problem is that we're burning ever larger amounts of fossil fuels, putting a greater concentration of carbon into the atmosphere than has been seen for millions of years. Though carbon has its positive...
