An Unfortunate History of White Actors Playing Other Races

enoch says...

@JiggaJonson
khan noonien singh was a genetically enhanced human prince from the 1990's and participated in the eugenics wars,which consequently was the reason for his,and his followers,fleeing to space and escaping the inevitable aftermath from their defeat.

his spaceship the botany bay was discovered 300 years later by captain kirk and the starship enterprise,perfectly preserved in cryogenic sleep.

you all may bow to my geek prowess.

i think this video is referring to the original actor and appear to have taken issue with cumberbatch not being a latin actor.

which i agree with you is pretty damn nitpicky.

on another note.
my first date ever with a young black woman was soul man,starring c thomas howel.i didnt really research the movie and was mortified when c thomas howel painted his face as black man.thank god she was a good sport.though she did bust my chops for months after.

true story.

When Plants Attack: A Time-Lapse

For a Venus Flytrap

The process continues until all that's left of the insect is its hard exoskeleton. (Unlike humans and other vertebrates, who have an internal rigid skeleton made out of calcified bone tissue, insects and arachnids use a more flexible, external exoskeleton to both protect and form the framework for their bodies.) Once the nutrients are depleted from the acidic bath, the plant reabsorbs the digestive fluid. This serves as a signal to reopen the trap, and the remains of the insect are usually either washed away in the rain or blown away by the wind.

Lovely sound effects.

I want to see what happens after a plant's finished digesting its victim. Does it dissolve the entire thing or does it drop a carcass when it reopens?

Enquiring minds want to know!

A Comedian's View on Postmodernism

highdileeho says...

I agree with dystosdopoigva'sdfvtoday. Some people talk like that, but those people aren't a representation of postmodernist culture. They're just like, you know, idiots? No different from the idiots that have existed since the beginning of humanity. Art, civility, perspectives on our role in society, pretensions, our relationships. Those where the things I was hoping for when I watched the video.

Upvote because I openly loathe people who talk like that. I went so far as explaining to a Botany assistant that the way she talked ensured that she would automatically receive less credibility than her peers. Regardless of how intelligent her ideas had been. She since went to grad school and studyed the coastal redwood symbiosis with fungi. When she gave her thesis presentation, I was pleased to hear her talk confidently and with conviction. I was the first one out of my seat to give her an ovation, she nailed the research.

Doctors Find Small Fir Tree Growing in Man's Lung

LordOderus says...

Well I don't know much about botany, but if the little pine had even a little bit of a root system, it had to be "growing" in some sense. Just inhaling a piece of a pine bough wouldn't come with roots attached. I know plants can do some growing without much light to work with. Did you ever do that experiment in middle school where you put a plant in box with dividers in it, and it grows around them to get to the light? Maybe they can do a little bit of growing without light, just based on nutrients and such?

I dunno, maybe it's some viral video for some pine flavored Russian cigarette or something. heh

Oh Dear God… This Is Our Country

The study of food relates to the human sciences (ethnology,ethnography, sociology, medicine, history), to environmental analysis (geography, climatology, botany, agronomics), and to the economy, where nutritional requirements are both an initial and a final stage (as in the markets for sugar and potatoes).

David Attenborough: Carnivorous Plants

rembar says...

There's actually a few small intermediary steps, to my understanding, in Rychan's otherwise neat explanation:
- Plants with more color and/or small pockets of mass that will catch rain water and accumulate sugary liquid from the plants glands or pollent are selected because they attract more insects for pollination. (Significant because it describes the creation of what will become a trapping ground later.
- Plants are selected for larger and larger liquid-holding pockets, which eventually evolve into phytotelmata.
- Insects fall into the phytotelmata, and local bacteria and parasites digest the insects, leaving basic nutrients that the plant can then absorb. (This bridges the evolutionary gap of the plant evolving the ability to trap insects at the same time as evolving the ability to digest the insect, a la blind watchmaker.)
- The plant develops small mutations (downwards-growing hairs, slippery sides) that lead to insects becoming trapped at a greater percentage. Some pitcher plants' evolutionary journeys end here.
- The intercellular methods of absorption of the digested insect nutrients are developed and eventually the plant evolves the ability to break the dead insect down into its basic amino acids through the production of proteases and phosphotases. (I haven't come across one definite mechanism for the evolution of the ability to create these enzymes, although viral transduction/transmission seems to me to be a pretty good possibility.)
- The modern day pitcher plant is born.

Carnivorous plants are a fascinating topic of biomechanics and evolutionary mechanisms. Some neat papers and links to check out:
