Elastic fiber. Elastic fibers (or yellow fibers) are bundles of proteins (elastin) found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle cells in arteries. These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed.
Some people think Alaska has less sunlight than other places. The opposite is true. Averaged over an entire year, Alaska gets 10-17 minutes more daylight per day than the rest of the country. If you include civil twilight, Alaska gets 40 minutes more light on average than the rest of the country. Even during those months of the year when Alaska has the same daylight hours as other locations, the days seem longer. That's because the sun rises and sets later in Alaska due to time zone boundaries.
The end of daylight-saving time will fall on Sunday, Nov. 6, at 2 a.m. At that time clocks will fall back and change from 2 a.m. back to 1 a.m. While some relish the idea of an extra hour of sleep, others dread the early nightfalls that standard time brings. However, the days have been getting shorter since the day after the summer solstice on June 20. The day length will not change drastically with the onset of standard time. For example, Birmingham, Ala., will get 10 hours, 41 minutes and 5 seconds of daylight on Nov. 5 and 10 hours, 39 minutes and 22 seconds on Nov. 6.
