This shows a snake.

Summary: A new study shows that the annular sea snake has evolved to perceive more colors than its ancestors. The snakes initially lost their color vision as they adapted to a lifestyle of burrowing under dim light, but sea snakes living in brighter marine environments have regained color vision. Two of the four intact copies … Leer más

How statistical physics illuminates sea ice, a key part of Earth's climate system - @theU

Since beginning to study polar sea ice at NASA in 1975, mathematician Ken Golden has helped document alarming shifts in seasonal variation, the thin crust covering the Arctic oceans. and Antarctica. There is far less ice now, and since then, the University of Utah scientist has spent most of his career applying statistical mechanics—the physics … Leer más
