Olympic results from 1900 to 2000 suggest that humans have gotten swifter and stronger. For instance, record times in the 100-meter dash have fallen from 11 to 9.8 seconds, and winning marathon times have steadily decreased from 2 hours and 59 minutes in 1900 to 2 hours and 10 minutes in 2000. Competitors in the discus threw just a little farther than 36 meters in 1900 but surpassed 69 meters in 2000, and in the long jump, athletes added more than a meter to their leaps over the 100 years of the Olympic games.
The fungus that causes athlete’s foot tends to get its start in the space between the third and fourth toes. That’s because the fungus responsible, Trichophyton mentagrophytes, prefers a warm, dark and moist collection of dead skin cells. The third and fourth toes are less mobile than their neighbors, creating a perfect home for the fungal invader.
Every 24 hours, a locust consumes its own weight in leaves.
A bruise can go through a series of color changes. That’s because the hemoglobin that is leaked from the under-the-skin blood vessel has a red-purplish hue. But hemoglobin slowly breaks down, creating biliverdin, which is green, and then bilirubin, which is yellow.
