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 first day of winter you'll hear it's the shortest day of the year and for summer it's the opposite. But what we should actually be saying is: Happy longest amount of daylight day!. It sounds silly, but it's a better reflection of day. A day only has 24 hours, so today can't be any longer than tomorrow. The sun rises at 6:13 a.m. here on the summer solstice and sets at 9:08 p.m. That's 14 hours and 55 minutes of daylight to enjoy! After Monday, the sunrise will continue getting a little later and the sunset a little earlier. Eventually by the winter solstice, we'll have a measly nine hours and 25 minutes of daylight. We aren't trying the change the world here. But you better believe if one of our meteorologists says Monday is the longest day of the year on air, we immediately get called out via email or social media.
