Did plate tectonics set the stage for life on Earth?

By Lisa Kaspin-Powell, Astrobiology Magazine

A new study suggests that rapid cooling within the Earth's mantle through plate tectonics played a major role in the development of the first life forms, which in turn led to the oxygenation of the Earth's atmosphere. The study was published in the March 2018 issue of Earth and Planetary Science Letters.

By ROBERT D. McFADDEN

He shared the 1997 prize in chemistry for his work on understanding how organisms get energy from their environments and process it to stay alive.

Matter: Hot Heads: Why Mammals Need R.E.M. Sleep

By CARL ZIMMER

Sleeping fur seals toggle between two brain patterns: one while at sea, the other on land. Researchers suggest that R.E.M. sleep serves to warm the brain.

ScienceTake: Breathe Deep: How the Antarctic Sea Spider Gets Oxygen

By JAMES GORMAN

They don’t have lungs or gills, and they are encased in hard exoskeletons. But somehow these marine creepers are getting oxygen from the water.

Matter: Every Cell in Your Body Has the Same DNA. Except It Doesn’t.

By CARL ZIMMER

The genome obviously varies from person to person. But it can also vary from cell to cell, even within the same individual. The implications of “mosaicism” are enormous.
