...Iowa State University used computer modeling to figure out how the length of a runner's stride might change the force applied to his or her bones and thereby affect the risk of stress fractures. Researchers recruited 10 male participants, each of whom typically ran about three miles per day, and calculated their risk of experiencing a stress fracture - about 9% over 100 days. By observing the participants running at varying stride lengths and recording the amount of force their foot strikes exerted on the ground, researchers were able to estimate the force each runner applied to his shinbone. According...
There are many units by which to measure the impact of climate change: degrees of increasing temperature, feet of rising sea level, dollars needed to adapt to a warming world. But a group of scientists in California have put forth an intriguing new unit of measurement: kilometers per year...
More than intuitive, this new index could also prove very useful, especially to conservationists who work to keep species from extinction. While the average velocity of climate change may be a bit less than a half-kilometer per year worldwide, according to the paper, it can be significantly faster or slower depending on the local topography. In deserts and other flat areas, such as the Amazon basin, climatic zones will move faster, while hilly or mountainous terrain will slow things up. "In the Northern Hemisphere, for example," explains lead author Scott Loarie, "north-facing slopes tend to be cooler...
Under the American Recovery and Reinvestment Act (ARRA), the federal subsidies pay 65% of the cost of COBRA premiums. Originally, the subsidy was to expire after nine months and unemployed families would have seen their health care premiums spike on average from $389 to $1,111 per month. This tripling of cost could have caused many families to drop their health care coverage just as Congress is on the cusp of passing the most far-reaching health care reform legislation in history. (See the Cheapskate blogger on COBRA...
...works: every car owner will be required to purchase a GPS machine that is able to send data tracking the distances of trips to a billing agency. Any motorist caught without the device will be fined. People driving a standard family sedan will be charged 3 euro cents per kilometer in 2012, with the tax going up every year until 2018, when it is expected to top out at an average of 6.7 cents per kilometer. So, for instance, a trip from Amsterdam to Eindhoven and back - a distance of about 250 kilometers - will cost the driver of a standard...
