Possibly there are people that would extract it -or try-, but unless you're in Africa and getting it from a traditional healer, I wouldn't recommend it.

While I expect local healers just make an infusion, these scientists used alcohol in their extraction. Besides alstonine's action against malaria, I read it has efficacy as an antipsychotic. What use do you have in mind for it? Antimalarial Activity of Ethanolic Stem Bark Extract of Alstonia boonei in Mice

Erhm...I wrote about ivy because you brought it up. And the word is graft, not graph. Who is grafting trees to ivy anyway? I'd say grafting is working with nature and in any case grafting does not affect evolution.

Ivy does not have a symbiotic relationship with trees, nor a dependence on trees. While [English] ivy won't flower until it climbs to a certain height -and the leaves change shape as well-, it will grow along the ground vigorously and can climb on rock to reach a flowering height. As to an evolved characteristic of ivy and other vining plants that lets them climb, it is the ability to form vessels, a characteristic that evolved in different plants and at different times.

It seems you do not intuitively understand that it's a matter of what folks grow up using, not a matter of complexity. Parlez vous avoirdupois?

Not all eruptions are driven by gases. Types of Volcanic Eruptions Technically, molten rock that has erupted is lava and un-erupted molten rock is magma. Magma originates in the mantle, not the core. Nothing but hot gas in the spoiler. What is your point? Honestly, most of what you have written is wrong and all of it uniformed. Do some reading.

Erhm...it's kewl? Science is always amendable? Just ran across it, found it interesting, and looked for somewhere to put it as it didn't seem to deserve its own thread. PS Per your OP, as far as how plate tectonics got started there is the matter of large Earth impactors and antipodal focusing. I think I put something up here on it in a thread on impacts. If your interested I can try & root it out.

It's been tried. I remember when I was working in the trades in the mid-70s and they gave everybody metric tape measures in an attempt to convert the shop. Rather than chaos it resulted more-or-less in a big 'meh'. Nevertheless it is ongoing and we are going down crawling and whispering millimeter by millimeter. TheMetricSystem.info

Your posts simply don't meet the standard of either this thread or this forum. Get a blog.

An unfortunate choice of words, particularly when associated with SA. The author starts the article saying, "Lets be clear: The planet is still getting hotter. The so-called pause, or hiatus, in global warming means the rate of temperature rise has slowed. The average global temperature is still going up, but in the past 10 to 15 years it hasnt been going up as quickly as it was in the decades before". Keep in mind it's a blog and the title meant to be eye-catching. Yes; very unfortunate choice of words. It certainly got your attention and gave you the impression there's no urgency. Way to go science blogger.

I knew who he was and yes, he expects us to take it seriously. Some peoples' kids.

The link you give leads to this: No genetic material is transferred across a graft boundary. Nutrients and chemical signals however do cross the boundary through the xylem and phloem and it is chemical signals that induce flowering. As to apples, their seeds do not breed true to the parent plant. Throughout history, genetic variation has from time-to-time resulted in sweeter and/or larger apples and people just happened to be around to recognize them and preserve the tree. When grafting was figured out*, any branches from the desired tree which are grafted to other apple trees will produce the desirable fruit only on that branch and its offshoots. If two plants are closely related it is possible to graft different kinds of fruits to the same root-stock. For example in the Genus Prunus you could graft an apple branch to a pear tree. *A History of Grafting

You're welcome. Well, keep reading. Temporal theory And from the Volley theory link: While all questions on how we hear are not answered, nowhere in any of this reading have I read that we have a loss of information as your initial question suggests. Common sense tells me that were it true we were missing out on something -other than frequencies outside our normal range- the experts would be all over the issue.

A turd by any other name would smell as sweet.

That is a great list, but why are these pseudo science and astrology isn't?... To be clear, I do consider astrology a pseudoscience.

That's an unfortunate choice of reference. While the original paper is interesting, your citation is a creationist rag which tries to use the original work as an argument for 'intelligent design'. You can probably hear me gagging from there. At least they reference the original. Full paper: Human Time-Frequency Acuity Beats the Fourier Uncertainty Principle Review: Human Hearing Is Highly Nonlinear Looks closer, but it's late and I spit up a little on myself after that article so I won't go point by point. Glad you have the speed is immaterial down. I recommend reading those 2 articles that StringJunky posted as they are very informative. Guten nacht.

Roger roger. So have you achieved any satisfaction to your understanding yet through all our efforts?

No worries. I'm working to the same end. Perhaps your animals comment was in view of MayKnow's dog article comment rather than MayKnow's mention of my post #26 that referenced animals. Anyway, MayKnow, what is it about post #26 that has you puzzled? Also, are you still in touch with your friend that made the hearing bottleneck comment? If so you might share this thread and/or ask for some clarification on the notion.

ms is millisecond. I would suggest you stick to learning human hearing first, and diregard other animals, otherwise you might be comparing apples to oranges and mess your learning up. I strongly disagree. While the others are laying out the technical terms as well as machine analogies to signal propagation, reception, and processing the central question is about animal hearing. I think my example of bats & dolphins being able to hear frequencies of 100kHz vs. our ~20kHz limit is a good practical easy-to-understand example for clarifying the issue of speed of sound vs. frequency. Moreover as I have tried to point out, hearing is entirely an animal exercise. What better way to understand it than with [eared] animal examples? Mess up learning with knowledge? Heaven forbid.

Roger. Accessing.... Mmmmmm.... That's pretty much as we did them. The plants were large and healthy [looking] and we left them in past the first frosts, but no sprouts ever developed in the axils. We have OK luck with Broccoli and will give that a go again, but we'll just put something else in the space we were using for Brussels sprouts. (Interesting history of them at that link though. Thnx. )
