1 of deep ocean's most turbulent areas has big impact on climate
...urbulence stirs the almost freezing-water near the bottom with warmer water that is closer to the surface much as you would mix cream into coffee by stirring it with a spoon.

...side the new channel. Often, small openings at the bottom of the newly formed channel will allow the blood to flow out. But if the openings arent large, blood flow inside the false lumen is slowed down, pressure increases, and clots begin to form.

The ancient DNA was discovered at the bottom of a two kilometer thick ice sheet and came from the trees, plants and insects of a boreal forest estimated to be between 450,000 and 900,000 years-old.
