Black, Hot Ice May Be Nature’s Most Common Form of Water

The discovery of superionic ice potentially solves the puzzle of what giant icy planets like Uranus and Neptune are made of. They’re now thought to have gaseous, mixed-chemical outer shells, a liquid layer of ionized water below that, a solid layer of superionic ice comprising the bulk of their interiors, and rocky centers.

The findings, published today in Nature, confirm the existence of “superionic ice,” a new phase of water with bizarre properties. Unlike the familiar ice found in your freezer or at the north pole, superionic ice is black and hot. A cube of it would weigh four times as much as a normal one. It was first theoretically predicted more than 30 years ago, and although it has never been seen until now, scientists think it might be among the most abundant forms of water in the universe.

Across the solar system, at least, more water probably exists as superionic ice — filling the interiors of Uranus and Neptune — than in any other phase, including the liquid form sloshing in oceans on Earth, Europa and Enceladus. The discovery of superionic ice potentially solves decades-old puzzles about the composition of these “ice giant” worlds.


Pretty cool - a new state of matter ...

Nope can not figure it.

'Ice' is obviously the wrong word for it.

Me neither. Although I think there is a hockey or stripper joke in there somewhere.

The graphic below demonstrates the concept and how it relates to pressure and temperature:

Still can't conceptualize it that easily. But ultimately, it just proves how cool science is!

So is that where all the water for the flud came from?

Well-detailed article announcing a new discovery about bacteria. They can sense the world around them. Duh.

Synthetic biologists hack bacterial sensors

The discovery is deep into the how-side of the chemistry and genetics involved.

Upshot is we now know enough about how some bacterial sensors, for like pH and CO2, work that we can alter how that chain of events works. We will soon be able to customize any of the sensors and its corresponding DNA switch/dial.

And, of course, we are already into fiddling with bacterial DNA big time. So now we have the ability to customize a sensor grid around any bacteria to activate DNA of our choosing, natural or artificial.

Just had a big shiver go up my spine.

It appears the future evolution of bacteria is being slowly syphoned off from Mother Nature© and into the capable hands of H. sapiens.
