What do you know today that you didn't know yesterday?

I am giving each of its eight tentacles it’s due.


Wait till I start posting on millipedes.

cuttlefish is able to rapidly change the pattern of both color and reflectivity of its skin. It can produce coherent moving patterns of color and reflectivity like iridescent zebra bands that move from head to tail or tail to head with its skin, much like an electronic display, and use this capability both to camouflage, and to communicate.

it can even do different patterns on either side to suite purpose, for example it might flash brilliant moving zebra stripe on its right side to signal to another cuttlefish, and hold a static pattern of different colors to camouflage itself against the background when seen from the left side.

Analysis of the photoreceptors in the cuttlefish eyes shows there are no provisions for reacting differently to different colors.   This strongly indicate their eyes are not equipped to distinguish between different color.   That cuttlefish can’t see color is amply confirmed by many behavioral experiments which require cuttlefish to distinguish otherwise identical objects by their color in order to obtain food.

Yet cuttlefish has the ability to quickly change their own color, and uses this ability to signal to other cuttlefish and also to camouflage themselves against background,

How cuttlefish can use color for display and for matching the color of their background without being able to see in color with their eyes is a mystery.

I've had my DNA run and discovered I'm part French.

Today I randomly surrendered to a German colleague!

Today I randomly surrendered to a German colleague!

What percentage? 
Afaik, those DNA tests can be quite wrong. "My Heritage" for example makes a difference between German and French heritage (aka continental) on one side and british/welsh. My results came back with 50% british, yea i know, i was as shocked as you were, but i KNOW i am 50% German/continental instead. When you read the small imprints on those sites, you will discover that the accurracy is only somewhat good, but not so exceedingly.

Tl;dr
There is hope! Do NOT despair!

French boots stomped in Berlin for many, many more years than the Germans were able to goose step in Paris.

France today is basically the same size as when germany first came into being.   People that were French back then are pretty much still French and still live at more or less the same places now.   Much of Germany as it was when it first came into being is no longer German, and further more much of the ethnic Germans who had lived in those areas for centuries had been driven out. 

I’d say upon final analysis, Germany’s high water mark was somewhere during the first 20 years after it came into existence in the aftermath of thr Franco-Prussian war.  but in the long run it is France that decisively won the long 1870-post 1945 war whose first battle had been  the Franco-Prussian war of 1870.

From the ‘If It Ain’t Broke, Don’t Fix It File’:

In the 1980s, archaeologists unearth some Neanderthal tools made from polished rib bones, estimated to be about 50 000 years old. There was widespread disagreement about what exactly the tools were, until they showed one to a traditional leather worker. She took one look and said, ‘It’s a hide burnisher. You use it to close pores in the leather and work oil into to make it waterproof. Mine look exactly the same.’

Flotsam is defined as debris in the water that was not deliberately thrown overboard, often as a result from a shipwreck or accident.

Jetsam describes debris that was deliberately thrown overboard by a crew of a ship in distress, most often to lighten the ship's load.

jetsom is flotsam that was jettisoned

Issac Asimov’s IBM Selectric typewriter (one of them, anyway) is ensconced in the Science Fiction wing of the Museum of Pop Culture in Seattle, Washington.
