So here’s one to end the blog-week: an unknown item of natural origin that many folks will have never come across. Who will be the first to identify it correctly? One notion that has occurred to me (when the Do-More devil is on my shoulder) is that I could pretty easily put together a “slide show” consisting of some number of familiar and unfamiliar objects from nature. A hundred  would not be beyond reach if beyond an audience’s sitting tolerance; 40 to 50 images …

From our Easily Amazed Department: a July 1, 2015 detailed piece of sub-cellular anatomy finds in a particular dinoflagellate–a motile predatory alga type consisting of a single cell per individual–this remarkable enormous “eyespot” that is far more than the dot of phototaxic pigment we learned about in in Biology 101 that you saw something like Euglena for modifying the flagellum to vaguely move towards the light for improved photosynthesis. This is a true “camera eye”, not a simple eyespot, and so like an animal …

Our eldest grandchild, Abby, is in the 8th grade now. I was in the same grade in 1962. I marvel at how much life on Earth has changed since then–not just human lives but the state of all life on the planet. Amazing, the degree of change our one species has caused in the geological blink of an eye is comparable in magnitude only to the shifts between eras caused by colliding continents, super-volcanic millennia or massive meteors slamming into Earth. My generation has …

The first time I saw a metallic blue contrail I thought it was just some odd play of light at that particular angle and time of day. The second time I saw blue razor-thin lines across the sky they existed alongside of the usual white contrails, with the two planes at similar altitudes, normal-looking passenger jets I supposed, visible as they created their tracks across an otherwise cloudless deep-blue sky. Over the past few months, I’ve seen this maybe a half-dozen times. Ann was …

There are enough possibilities for this topic that are based on solid science to warrant a longer look for me, and then there is some over-statement and razzle-dazzle as well. I will let you wander and browse the links and videos on the web sources listed here and you can make your own judgment about it all. N Tesla’s experiments from more than 100 years ago apparently transmitted electricity over a distance of some miles without wires. This is not the same as transmitting …
