Jesse A. Logan ’77 PhD is hiking up a mountainside in Yellowstone National Park and walking back in time. He starts at 8,600 feet above sea level, in a forest thick with the scent of fir and lodgepole pine, and with almost every spry step, the scenery changes. There’s an understory of grouse whortleberry, then accents of mountain bluebells and higher still, the whitebark pine, one of the oldest organisms of the Interior West.
Finally, the vegetation gives way to large swatches of scree. Logan’s 70-year-old legs have gone up 2,000 feet and back more than 10,000 years, from the lush vegetation of the twenty-first … » More …
An insect’s small size gives it the gift of relatively greater strength. The newly discovered South African cockroach Saltoblattella montistabularis takes advantage of this fact plus several other features, as Washington State University entomologist Carol Anelli describes here:
This is very cool for several reasons.
It is a wingless cockroach, described for the first time only two years ago, and the first existing roach known to jump. It achieves this feat with modified hind legs that possess long femurs invested with enlarged muscles. These long femurs—akin to the longest bone in the human body—help give grasshoppers their great jumping ability.
I want to walk on water, climb walls, and dance on the ceiling. If insects can do it, it’s only fair that I should, too.
But this thing called physics has decreed otherwise. Carol Anelli, a WSU entomologist, can tell you why, having a lifelong fascination with ways insects can at times make us seem relatively slow, earthbound, and weak.
