Long walks along the coast are a delight in any weather, year-round...

I've enjoyed the recent storms, for their aesthetic value. :)

What science has been saying for years, but is now saying loudly:

I know this, you know this, but it isn't happening on its own, so it has to be emphasized by scientists:

New plant-focused diet would ‘transform’ planet’s future, say scientists

The Vija Celmins show is one of the most compelling exhibits I’ve seen in years.

The Vija Celmins show is one of the most compelling exhibits I’ve seen in years. Her steady dedication to her subjects over time, and the depth and detail of her work, is remarkable.

Celmins is a Great Artist.

I approve of the person who posted this message of love on SanFrancisco's Ocean Beach, which I observed today.

Spiders Can Fly Hundreds of Miles Using Electricity #Science #Spiders @TheAtlantic

On October 31, 1832, Charles Darwin walked onto the deck of the HMS Beagle and realized that the ship had been boarded by thousands of intruders. Tiny red spiders, each a millimeter wide, were everywhere. The ship was 60 miles offshore, so the creatures must have floated over from the Argentinian mainland. “All the ropes were coated and fringed with gossamer web,” Darwin wrote.

Spiders have no wings, but they can take to the air nonetheless. They’ll climb to an exposed point, raise their abdomens to the sky, extrude strands of silk, and float away. This behavior is called ballooning. It might carry spiders away from predators and competitors, or toward new lands with abundant resources. But whatever the reason for it, it’s clearly an effective means of travel. Spiders have been found two-and-a-half miles up in the air, and 1,000 miles out to sea.
