Re: most complex abiotic (nonliving) molecules

That's great. Living nature wins again. Lignin is a huge molecule. Are there any complex molecules that develop without living syatems?

most complex abiotic (nonliving) molecules

Has anyone has gathered a list of nature's most complex non living molecules? What abiotic molecules have the greatest number of unique atoms, most daltons, etc. I'm thinking about crystals, but these generally only have a few unique elements repeated over and over again. Thanks :)

myosin and actin constituent amino acids?

Do we know what the constituent amino acids of myosin and actin are, and the ratios of these amino acids in muscle tissue?
Thank you.

meiome and genome

I thought eukaryote genetic inheritance came simply from the adding together of (recombinant) haploid chromosomes in the new zygote. But there is a lot of RNA involved? A crowd of unique proteins and mRNA in addition to the chromosomes in the gamete? See this: It is also noteworthy that during meios...

Genetically engineer starchy plants for biofuel

For a biofuel solution (no pun intended) how about genetically engineering starchy plants that grow in poor soil. I'm thinking developing a type of switchgrass with big fruit, or maybe something with a starchy root.
Is it fairly easy to break down starch into sugar and from there into ethanol?

Re: vision in water and air.

Seals and dolphins, cormorants and iguanas, etc. I'm not arguing with you. I mean to point out that i know of no reason two solutions as different as water and air should be transparent in the same spectrum. It's a heck of a coincidence. It allows for eye physiology such as rods and cones, to be equ...

Re: vision in water and air.

Yes Jackbean, I was referring to the fact that water and air are both transparent in the same spectrum, mostly, so that species don't have to have (tremendously) different vision strategies for use above or below water. Generally, any animal that can see above water can see below it, because water a...

vision in water and air.

I read that air and water are transparent to visible light. Animals have adapted so their eyes see these wavelengths. My question is, how surprising is it that both air and water are transparent to the same frequencies? Is that just cosmic chance? (So that sighted animals can see underwater and abov...

Re: conservation is necessary to human survival.

Thanks for that review. Last night at work we carefully took a wolf spider out of the building and let it go. I like spiders because they are essential to insect control, and ecological balance. I think we need all the pieces of the ecological puzzle, but I can't put my finger on why. I can't prove ...

if cellulase microbes get loose

Because cellulosic ethanol would be such a great source of fuel if it can be produced economically, people are working on creating cheaper more effective "cellulases". If the microbes that create these improved enzymes get loose, could they eat all of Earth's plants?

Hello all again,
I hope this is a welcome post. I have made a web forum with the purpose of discussing the invasion of Asian carp into the Great Lakes. It is at the following url:
