The Download: ancient DNA, and offshore wind

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

DNA that was frozen for two million years has been sequenced

What's happened: After an eight-year effort to recover DNA from Greenland's frozen interior, researchers say they've managed to sequence gene fragments from ancient fish, plants, and even a mastodon that lived 2 million years ago. It's the oldest DNA ever recovered.

How they did it: The researchers examined genetic material that was left behind by dozens of species and washed into sediment layers long ago. The DNA was preserved by freezing temperatures and bound to clay and quartz, which also slows down the process of degradation.

Why it matters: The genetic findings, which paint a picture of an era when Greenland was covered with flowering plants and cedar trees, could provide clues to how ecosystems adapted to warmer climates in the past. Read the full story.

The wild new technology coming to offshore wind power

Wind power is one of the world's fastest-growing renewable energy sources, and soon its reach might expand even further. This week, California is auctioning sites off its coast that could house the first floating wind turbines in the US.

There are already a few demonstration projects around the world for floating offshore wind turbines, but the technology is entering a new phase, with more governments setting goals for installations and larger projects entering the planning and permitting stages. California could be a major testing ground for the technology. But what it would take to actually happen, and what will California's auction mean for wind power globally? Read the full story.

Quote of the day

It's not a good look. It's yet another unspoken sign of disrespect. There is no discussion. Just like, beds showed up."

-A disgruntled Twitter employee tells Forbes about beds mysteriously appearing in the company's offices without any warning, presumably to enable staff to pull crazy hours.

The big story

Is your brain a computer?

It's an analogy that goes back to the dawn of the computer era: ever since we discovered that machines could solve problems by manipulating symbols, we've wondered if the brain might work in a similar fashion.

Alan Turing, for example, asked what it would take for a machine to think" back in 1950, wondering that if machines could think like human brains, it was only natural to wonder if brains might work like machines.

Today, experts are divided. We asked them to tell us why they think we should-or shouldn't-think of the brain as being like a computer." Although everyone agrees that our biological brains create our conscious minds, they're split on the question of what role, if any, is played by information processing-the crucial similarity that brains and computers are alleged to share.
