You guys need to look at the neat piece of art on the front of one of my books:

This is Alexandrite, it’s also called “emerald by day, ruby by night”
It changes colour based on whether the light source is from the sun or from a candle.
It does this because Alexandrite strongly absorbs yellow light due to chromium ions in its crystal structure, leaving the other colours behind. Light from the Sun emits all colours, but it peaks in the green, and our eyes are most sensitive to green, so in Sunlight Alexandrite is green.
Incandescent lights are things like candles and filament light bulbs. They also emit all colours of light, but they peak far, far into the red, so there’s not nearly as much green or blue, so under those, Alexandrite is red. 
Gemstones are awesome.

Ancestor’s ‘Leaky’ Membrane Answers Big QuestionsAll life on Earth came from one common ancestor – a single-celled organism – but what it looked like, how it lived and how it evolved into today’s modern cells is a four-billion-year-old mystery being solved by researchers at Univ. College London using mathematical modeling.Findings published in PLOS Biology suggest for the first time that life’s last universal common ancestor (LUCA) had a ‘leaky’ membrane, which helps scientists answer two of biology’s biggest questions:1. Why all cells use the same bizarre, complex mechanism to harvest energy.2.

Ancestor’s ‘Leaky’ Membrane Answers Big Questions

All life on Earth came from one common ancestor – a single-celled organism – but what it looked like, how it lived and how it evolved into today’s modern cells is a four-billion-year-old mystery being solved by researchers at Univ. College London using mathematical modeling.

Findings published in PLOS Biology suggest for the first time that life’s last universal common ancestor (LUCA) had a ‘leaky’ membrane, which helps scientists answer two of biology’s biggest questions:

1. Why all cells use the same bizarre, complex mechanism to harvest energy.

2. Why two types of single-celled organism that form the deepest branch on the tree of life – bacteria and archaea – have completely different cell membranes.

If anyone in Carbondale plays tennis, I’d love to play some weekend. I’m terrible because I haven’t played much in the last 4 years, but it’d be fun to pick the game back up. Just putting this out there to see who’s interested. I also have an extra racquet.

I just found a fully functional, 32 in CRT by the dumpster. I can’t decide whether to keep it or sell it on ebay and tag it with “lagless” and “video games”.

biomorphosis:

The maned wolf is the largest canine species in South America and closely resembles a red fox on stilts because of its long legs. It is neither a wolf, fox, coyote, or dog  but rather a member of its own Chrysocyon genus, making it a truly unique animal. They possess a mane that runs from the back of the head to the shoulders which can be erected to intimidate other animals when displaying aggression or when they feel threatened. 

Unlike other wolves that live in packs, maned wolves do not form or hunt in packs but prefer to live alone.  Maned wolf is considered as the last surviving species of the Pleistocene Extinction, which wiped out all other large canids from the continent.

Installing CYGWIN because mad at a phylogeny that MEGA is spitting out for an rRNA sequence BUT I think I found software that takes into account the structure of the rRNA (it’s for linus; hence, cygwin). It’s for a class. I don’t know how to phylogenetics, but I’m learning.
