Study of colorful crayfish challenges theories of bright coloration as adapted phenotype

A pair of biologists, one with West Liberty University, the other with Arizona State University, both in the U.S., has found evidence that challenges theories surrounding bright coloration always functioning as an adapted phenotype.

Another interesting study.

Scientists identify brain circuits tied to the behavior of schooling fish

A flock of migrating geese glides through the summer sky in an unmistakable "V" formation… a thundering herd of bison rumbles across the plains as a formidable group... and a massive school of sardines swims mesmerizingly in unison.

Charles Darwin speculated the bright colouration, weird feathers and such might simply be for sexual selection. Beauty might have its own ways. There hasn't been huge follow up on the idea he threw out there for future research, as that old everything has a functional purpose view have long held sway. That's neat with the crayfish.

It's neat that we can prove glassfish learn and remember. Remembering is a big part of thinking and intelligence as we define it...

This really has potential.

Smart soil can water and feed itself

A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients.

Now that is interesting - for our species as a whole, but also maybe someday soon to stop me from killing houseplants.

I think for some fish things like stripes or bright colors help them with schooling.
