The science and nature thread v. We tried this before
« on: July 25, 2013, 11:38:58 AM »
Ok, let's try this again. Post cool stuff you read here and there about science and nature.

I'll start:

1) Scroll down a bit, there's a woman putting on sunscreen while being filmed by a camera that only sees UV light. So cool.

2) "Mudskippers", fish that evolved the capability to walk on land. It's eerily close to all those depictions of evolution where you see a fish dragging itself onto land:

Oh man, that's awesome. I mean, it's precisely what you'd expect, but still really cool to actually see it.

look at her shoulder/arm in that bottom pic.  Does that look right to you?

Yeah, it does to me. She is skinny, sure, but she just happens to have an angular face.
If I  may say so, it looks to me that due to the obesity epidemic your "normal" has shifted to the point where a skinny person looks anorexic to you.

I finally finished MLK's autobiography yesterday, which means I can return to Brian Greene's latest book about the origins of the universe. I love reading that stuff, even though I expect a ton of stuff I already know.

I don't know...in that last picture, the lady's right arm/shoulder looks so thin as to be deformed.

     :omg:

Her face is fine.

Very cool site, though!   :tup

She looks a little bony and underweight to me too... but we are Americans after all, so that must mean that the obesity epidemic has completely skewed our perception of this matter.

A very cool bit about the lady's UV pic:

Quote
You can also see that the eyes appear entirely black in the UV image, this is because eye chromophores absorb UV rays for protection against UV light damage.

Her chest looks rather concave, as well.   ???

Yeah...she needs to eat more than a couple lf almonds for lunch. Has nothing to do with the American obesity epidemic..Jesus...she's incredibly skinny. Bony in fact. But the UV absorption thing is cool. Anyhoo! Back on topic.

If this thing came out of the woods and approached me, I think I'd wet myself getting away from it. Very cool though.

This is pretty cool: http://www.chron.com/news/houston-texas/houston/article/50-000-year-old-forest-of-fresh-trees-found-in-4657102.php

Interesting. Bummer that the article doesn't explain the mechanism of the preserved underwater forests. It seems to me the forest must have suddenly been buried under the water, since a gradual water level rise would just slowly have killed off the trees.

I was wondering that as well...I'm figuring the area was below sea level at the time, and whatever earthen dam was holding back the water broke in some catastrophic event and flooded the whole region.  that's pretty much the only way I can figure that it would go from dry to anoxic quickly enough to have this kind of preservation occur.

There's a more in depth article here http://www.livescience.com/37977-underwater-cypress-forest-discovered.html

Quote
The Bald Cypress forest was buried under ocean sediments, protected in an oxygen-free environment for more than 50,000 years, but was likely uncovered by Hurricane Katrina in 2005, said Ben Raines, one of the first divers to explore the underwater forest and the executive director of the nonprofit Weeks Bay Foundation, which researches estuaries.

I think that explains why the forest was conserved long term, but I think the immediate conservation is still mysterious to me. Anything gradual would have rotted the trees.

For once some positive news when it comes to CO2: They are testing CO2 sequestration in basalt.

I find that I get a lot of my interesting science facts from xkcd recently.  Apparently, there is a canyon larger than the Grand Canyon buried in sediment in the lower Nile river valley.  This was discovered when core samples were drilled for construction of the Aswan dam while looking for bedrock.  The bedrock near the river banks was under about 30 feet of sediment, whereas in the center of the river, it was 900 feet below sediment. Further down river, it is much deeper.

http://groups.yahoo.com/group/InPursuitofWisdom/message/3821

Summary from the link:

A vast deep canyon, which five million years ago looked like the Grand Canyon of Arizona, lies buried under Cairo, and extends southward for 600 miles to Aswan, Egypt, where its further path is lost.

Dang, that is huge. I just looked up where that dam is that marks the end of the canyon, and it's at the southern tip of Egypt!  :omg:

The Earth as seen by NASA’s Cassini Spacecraft on July 19, 2013. Were the small dot, halfway down the image and slightly to the right. Saturn and its rings are in the foreground. The blue haze is sunlight refracting from Saturn E ring, which is made of material shot into space from the moon Enceladus. Credit: NASA

And a slideshow of images of the earth from space... the first from 1946!

There were times when Rik and I were writing together when we almost died laughing. They were some of the most carefree stupid days I ever had, and I feel privileged to have shared them with him. And now he's died for real. Without me. Selfish bastard.

This is my favorite quote ever, and I praise whoever made the cartoon to go along with it.

The coolest part is that the kid in it is Carl Sagan and the library story is one he used to tell all the time.  :heart
