Haha, nice! Thanks for sharing it. You don't play [URL="https://fold.it/portal/"]foldit[/URL], do you? This is what I do when I can't get a better score by "honest shaking and wiggling" those proteins, and I am totally stuck on the "mental image" side (i.e. I have no freaking idea how I could fold it better and how the other guys there got a better score) - I just change one chain or node in a totally illogical position, or use a rubber band that will totally deform a part of the respective mucus in some impossible contorted way, and start again with "honest shaking and wiggling", hehe. Sometimes that results in better score :razz:

Never played Foldit, but I am quite adept with mucus, I'm told.

Neat classification of astronomical bodies into Terran, Neptunian, Jovian and stellar worlds based on a mass-radius relationship.

Everything from Rhea to the Earth in our solar system is well described as "Terran"; Neptune and Uranus, of course, are Neptunian; Saturn is a borderline Jovian/Neptunian; brown dwarfs are nothing special, just high-mass Jovians in this classification. Stars are everything which burn hydrogen, though the classification effort drew a line at which their expected lifetime exceeds a Hubble time, or circa 0.9 times the mass of the Sun.

There is also a well-argued that the "super-earth" category of exoplanets is a figment. The Terran-Neptunian boundary occurs at twice the Earth's mass whereas the low end of the Terran worlds have 4e-5 Earth masses, so the Earth (and Venus) is a typical "super-earth".

Indeed.

We should soon be sending out micro probes into deep interstellar space (driven by lasers) to take measurements as they fly by at high speed.

Looks like someone forgot to use enough lighter fluid.

[Also check out the catnip-as-mosquito-repellent story linked on the same page. Interesting, but what are people who don't like the taste of the stuff or whom it makes hyperactive supposed to do? Feed it to our cat and then rub ourselves all over with the cat? :)]

I had been thinking about a system of classification system for single objects (as opposed to groups or structures that would handle all sorts.
Basically the first divide would be for any object that has in the past, is currently, or will in its future fuse. The fusors would be subdivide and adjectives would get added as needed to identify things like proto-stars.
The planetary objects would be divided some what similar to the way this paper suggests. My classification would allow a rouge planet to still be a planet. It would also deal with moons and moons of moons, etc.

Objects could change categories (if mass gets added or removed) and may get adjectives changed, but a full description would include any important past history.

I think you mean a rogue planet ...

Bogoslof Island/volcano, North of Aleutians erupts
 

We flew from Chicago to Hong Kong, once. The plane went North out of OHare. Coming down the "other side" of the arc could have been impacted by one of these plumes. Fortunately, that did not happen.

Sorry for the cheesy source. There are some good links, and the article itself is not bad.
Here some Alaska Volcano Observatory pages on Bogoslof:

Major issue: the ash plumes above 20,000 ft affect North American<->Asian air routes. Bogoslof puts some ash plumes up to 35,000 - 45,00 ft.
Nice electron microscope image of ash particles-

Blame spell check and dyslexia.

From the "servers as space heaters" article in another thread, I picked up this story on sharks puking. Under stress, they may disgorge all sort of things, from feathers and other indigestible items, to entire seals. If that weren't enough, they can also bring up the entire stomach, essentially to clean it, and then gulp it back down.

The seal story was of a great white shark which had a larger shark come up behind it. The smaller shark ejected the seal and swam away, while the larger one ate the seal.
