A Very new kid on the block!

Posted on: September 14, 2007 4:29 PM, by Bright_Lights
Hello again, it has not even been a day yet, but I feel that I should quick post something. Some of the comments from my previous blog have pointed out interesting ideas as to the correlation between protein folding and memory storage.
Proteins inside neurons would work well in storing and possibly managing information, but they don't work quickly enough and I suppose it would be fairly difficult to research proteins in the hundreds of thousands of specialized neurons. I was also informed that much of the "protein hypothesis" is old news that was torpedoed in the 60's for the "synapse hypothesis" due to lack of technology to model such interactions. However, the "protein hypothesis" has reared its head once again in recent years and (I feel) is worth looking into further, although it may still be hard to conceptualize. Also, it was pretty insulting to say that little research has been done in this field and that Allan Pack is the sole researcher still working on this. Many researchers are still busy working away on this subject (don't believe everything MPR tells ya').
I haven't had a chance to read some of the research recommended to me yet as I am still just a kid (a fact that some have pointedly stated to me, thanks for the insight) and still have a life before graduate school (i.e. I run Cross Country, talk to girls, and watch movies outside of studying). Continue to post further links on this please! I will do my best to be more to the point (shorter blogs) spell correctly (sorry Myers) and stop feeding you heathens further fuel for the spiritual flames of damnation :P (I'm a Christian, get over it!). Thanks for the comments, continue to inform me on how I can do a better job at this.
This is the last time I'll say it and will truly stick to science after this, but I can't resist, God bless!

Correct me if I'm wrong, but as a non scientist I was always under the impression that talking to girls actually lost you a position with most Graduate Biology Programs!!

Just one thing: it's a blog post; the blog is the whole thing (short for "web log").
Apart from that, keep up the good work. So far, the protein hypothesis sounds very vague to me, but I'm here to learn!

As someone who's celebrating his first 39th birthday tomorrow, I'm going to say this: kids these days.

Eh, look on the upside: As long as you're willing to give up a hypothesis if it's shown it doesn't work, choosing the less-researched version of two plausible possibilities may well put you on the fast track to big discoveries =)

I would say; Don't believe anything you hear and only half what you see. Accept input with an open mind, investigate the evidence, then decide for yourself, remembering always that "gut feelings" are reliable only 50% of the time in a two way choice.
You would be amazed at the numer of hoaxes PZ has posted here and a good number of we skeptics have accepted them. On the other hand some of the others usually reveal the truth.

Oi! Orwell! Talking to girls is a good thing in the biological sciences: it's the one branch of science with a fairly significant population of female scientists. Unlike computer science or, um, I dunno, physics. We rock!
Having a life, on the other hand, that's frowned upon in graduate school. And, even if it were smiled upon, who has time for a life?
Posted by: Inky | September 14, 2007 5:48 PM
I'm confused? Male or female? Your demeanor is female (handle, verbage, smilies, etc), but you say "talking to girls" like it's a sexual thing.
Got any light to shed on this? I'm not trying to be mean, it's just that I was very, very surprised to see that mention of talking to girls and it's implications...

Oh come on... Bright_Lights? Quick Google turned up this: Bright Lights is a discipleship group to train young ladies in godliness.
What is a "bright light"?
It is a girl who knows how to respond just right to people and circumstances. It is a girl who has Biblical convictions and commitments, and is able to go through her teenage years strong for the Lord without stumbling as many do. It is a girl who touches the lives of others by her servant's spirit and the message of eternal life through Jesus Christ. God wants bright lights! There is a great need for more of them in this generation of darkness.

Hope you become a good neurobiologist--or whatever it is you decide to do. I'm just 15 and taking my first biology course, so I don't know much about this kind of thing, obviously. Try to ignore any of the mean comments that might be posted, people tend to be surprisingly stupid for some reason, even on Pharyngula.

I hope this is a useful assignment for you. As for "I'm a Christian, get over it!", don't act surprised when people take your bait ("God bless"). If you feel the urge to discuss religion here, your assignment seems broad enough to encompass that, and many people would readily respond. If you're not interested in talking about religion, I'm not sure why you'd bring it up. Except to kind of deliberately slap people in the face, which I admit is kinda funny.
Anyway, you'll find that there are quite a number of regular posters on here who are Christian too. It's not always obvious, because they don't have much reason to bring it up when they're discussing scientific stuff, but some of them have interesting contributions on a wide range of topics. We also get some persistent creationist nutjobs posting on here, so the rationalists here are often expecting a fight with the superstitious.
Anyway, best of luck. As you find interesting source material about this stuff, be sure to offer us links!

Posted by: Wrought | September 14, 2007 6:36 PM
I'm no neurobiologist, but it strikes me that one of the important differences between natural and artificial systems is the danger of false dichotomy or inappropriate reductionism when attempting to describe the natural system.
Artificial memory, like anything human-designed, will use well-understood building blocks assembled in well-understood ways to produce predictable, repeatable behavior. In the case of artificial memory, the basic building block is a digital switch. Each switch behaves in a straightforward deterministic manner independent of the context in which we place it. A switch is not memory any more than a LEGO brick is a toy castle. One part is designed and is used as a self-contained subordinate unit in constructing the other.
Natural systems don't necessarily work that way because they were not designed. No conscious agent was trying to control for a particular outcome. If you are trying to answer a question like "are memories stored in synaptic arrangements or in protein folding configurations" then you might overlook the possibility that neither mechanism is wholly subordinate to the other, and that the abstract high-level notion of "memory" in brains cannot be completely described in terms of either alone. The mechanisms may in fact feed back into one another in ways that are difficult to predict, describe, reproduce or control. The principle of parsimony is important in descriptive science, but nature is in no way required to cooperate with a prescriptive parsimony.
It is an important skill to recognize such subtle sources of bias in oneself, to be able to ask yourself what you really know and why you think you know it, and to revise or suspend assumptions that cannot be justified.

Posted by: Russell | September 14, 2007 7:01 PM
~K isn't all that cute, and you typically whoop ass. I suppose everything came together in a kind of synergy of cute, and I made a hasty reduction pinpointing the tilde as the cause. It had its role to play in the MySpace tone, but is probably harmless by itself.
Internet gender confusion always starts the worst kinds of conversations. I think fedaykin means to say that the poster is openly Christian, and openly attracted to women, and therefore seems to be a man.
I know I'm going to get dogpiled for saying that, but I shouldn't be. Here's why:
1) I did not suggest that no Christian woman could be attracted to other women.
2) I did not suggest that there is no such thing as a Christian woman who openly admits to being attracted to other women.
What I did suggest is that people of the second variety are a vast minority among Christians, and so it isn't an unreasonable conclusion to reach at all (and I am not to be blamed for that, blame for that falls on the Christians). The problem really boiled down to: Either this poster is a Christian girl who is attracted to other girls, or this poster is a male. Parsimony suggests the latter, but the mannerism (and I'm going to get attacked for saying this) is that of a teenage girl (who, for example, have sometimes been known to write in pink ink and put hearts above their 'i's, and commenting on that trend doesn't make me a sexist), and that's why fedaykin is confused.
Why didn't fedaykin say that? Because if he did, his post would have been as long as this one. It is possible to be oversensitive. I don't mean that in the dismissive, trivializing and dishonest sense racists, chauvinists or bigots usually mean it in. I mean it exactly as it appears: It is possible to be oversensitive.

Thanks for the fast comments, I'm actually a guy and picked the name "Bright Lights" because I knew that there would be people far more advanced in this feild than me. I figured some of the responses I would get back on the material would leave me like a deer in the head lights or "bright lights." It's got nothing to do with spirituality, although I do like the comparisons.
Let me know what some of the hot topics in the field of Neurology are right now, then you won't have to listen to college kids talk about protein folding with respect to memory function.

Since my students are both men and women, and most have chosen pseudonyms that don't make a big deal out of their gender, maybe it would be a good idea to not worry about the content of their chromosomes and think more about the expression of their thoughts. Would it matter whether they were male or female? None of you are going to get to date them, after all.

Russell (#31):
The context of Bright Lights' first post made it a little clearer. "MPR" is the 800-pound gorilla of the public-radio world, Minnesota Public Radio. Bright Lights was specifically talking about a recent MPR effort to break into contemporary pop music broadcasting, a station called "The Current."Posted by: Rieux | September 14, 2007 9:08 PM
Kudos to Bright_Lights. He was not only the first of PZ's students to dip a toe in the blog pool but he jumped straight in at the deep end with his protein folding post.
As for some of the complaints - well I can't see anything wrong with "Bright_Lights" as a screen name so I'd stick with it myself. That "deer in the headlights" image is justification enough (especially with this audience) and the thought occurs to me that it is, maybe, a pretty good collective noun for PZ's students.
Still, if you do change your screen name then how about well er -- speaking as an aged heathen, I suppose I shouldn't say this but I'm also an old curmudgeon so I'll say it anyway -- so how about "God_Bless" :-)

Despite PZ's admonitions, most of us are harmless and well-intentioned. We are also generally interested in and often make our living in the purview of science. However, I think it's safe to say that most of us are also pretty dismissive of religion and that topic will only lead to argument that is repetitious and unproductive. So, if we want to avoid debates without solutions, let's all just avoid the subject that generates the vast majority of them and leave that discussion for other and more appropriate venues.
Posted by: Milo Johnson | September 14, 2007 10:07 PM
Nice recovery, dude. You oughta give tips to Rob Knop, an "openly Christian" ScienceBloggerer who's been chewed on a few times by the Pharyngulites.
Yeah, yeah, I know it's not all of PZ's fans. But then, it's not just them, either. Any net-crowds tends to pick up that sort of "sharp edge" unless the moderators put serious effort into filing them down. For that matter, I suspect a lot of people are still getting burned by the whole "no tone-of-voice in text" thing -- it's easy to write something that you think sounds like a sarcastic tease, but which your reader takes as viciously hostile.

Welcome, Bright Lights!
I'm not a scientist - just interested. I'm a technical writer in Toronto, Ontario.
The thought of proteins folding to help us learn makes sense - there must be some way to create a physical, or electropotential, trace in the brain. I don't know anything about that. But I did read about some research where amnesia patients who couldn't form new long-term memories were given Tetris(tm) to play with. Then they were watched when they went to sleep that night. When they started to dream, researchers woke them and asked them what they were dreaming about. They were dreaming of falling shapes! And they didn't remember why. That adds credence to the hypothesis that we dream to integrate our memories of the day. And the process seems to be running even when there's a hitch in the transcription to permanent memory.
Further, what's causing the hitch? Maybe there's a centre for protein-folding (chemical) instructions or for producing the right enzyme - and that's what gets damaged in those unfortunate amnesiacs.

IT'S PERFECTLY OK TO TALK ABOUT PROTEIN FOLDING AND MEMORY.
The best candidates for memory mechanisms now are things like LTP... these are nice and all but it's important to remember that the evidence linking them to actual memory traces (whatever those are) is very slim. There are no known physiological changes to synapses that last as long as memories do.
Some people brought up prions in your previous post. It's worth noting that many neuronal proteins contain domains (usually poly-Q tracts) that predispose them to forming prion-like "mis"-folded forms. Interestingly, these domains are completely dispensible for the known functions of these proteins, but are under intense negative (stabilizing) selection.
Why? In the case of the synaptic protein CPEB (which regulates the synthesis of other proteins at particular synapses) Eric Kandel and Sue Lindquist have proposed that adopting a prion-like aggregate form might function as a long-term synaptic tag. Essentially they are proposing prion-lik protein aggregates as a mechanism for permanently altering a synapse.
See the back to back Cell papers by Kausik Si from a few years back (Dec 2003).

Nicely done. It's rare to see someone manage to go through a list of alleged flaws, admit to the one or two that are actually relevant, and stick to their guns on the rest. The touch of snark was also very good - and certainly called for.
The only thing I'd suggest you do differently is to provide some more references. For example, when you say:
without providing details about who the "many researchers" are, it makes me wonder (a) who these other researchers are; and (b) if you're just making that up. That second part's not really fair to you, but after spending lots of time debating with people online, that's an automatic reaction. It wouldn't surprise me if I'm not the only one here who has it.
If you cite references when you post here, I think it will help you in a lot of ways. It'll make it clear to the overly skeptical (like me) that you do know what you're talking about. It'll make it clear that you do know what you are talking about. It'll make it easier for people to follow your arguments, and find more information if they are interested in the subject. It'll also make your posts clearer - even if it also makes them longer.

In my opinion there are plenty of good reasons not to be a Christian, but social pressure isn't one. I'm glad to see that you didn't just run away in fear after the deluge of comments. That sort of courage will be a great asset if you ever scrutinize your religious beliefs objectively and become an atheist.
