Since the year is winding down, I had a question for the readership: what's the best scientific paper you read this year? Let's restrict the field to chemistry and biology; I'm not ready for particle physics. And I don't necessarily mean "best written", although you're free to nominate some if you can find any that stood out. What I had in mind was more "Most interesting" or "Most unexpectedly useful", or "Most surprising". I've got a couple in mind myself - I'll turn the suggestions into another post or two.
I have to say that paper by University of Kentucky team that Published data linking retinal toxicity to 21-Mer siRNAs. This was a seminal finding that foretells other surprises in store for this gene silencing technology. Many have lot of stake invested in this area.
There were a ton of them, but to a clinician treating inherited disease, this one was the most striking, showing how little we really know about the influence of the genome on disease.
The GPCR paper was a tour de force (and the GPCR guys will probably get a Nobel Prize at some point) but I don't regard it as particularly surprising or unexpected. For most unexpected result I will probably nominate the diiron protein that spontaneously generated a *covalent* bond between a phenylalanine and valine (Science). Very unusual: DOI: 10.1126/science.1205687.
Another nomination for best paper would be the piece on FoldIt, the protein folding game, which demonstrated the power of harnessing collective intelligence to solve a problem as thorny as protein folding. I think the paper paves the way to similar fascinating endeavors in the future.

This protein has such a fundamental role in mitochondrial function and pathology, its hard to believe it won't be an interesting drug target in the future.
Don't know about the best one but I can surely nominate the worst: "Womanspace" in Nature.

The Zhu et al paper in Cell (PMID 22153080) demonstrating the role of PKR (dsRNA-activated protein kinase) in learning and memory. What a kinase involved in recognition of viral infection has to do with learning is beyond me, but a cool connection.
Alternatively, a really interesting/possibly scaleable approach to looking at RNA splicing in the Vargas et al paper in Cell as well (PMID 22118462).
An unbiased look at the histone code - simply pull out all the core histones, do some mass spec and work out what all the different modifications actually are. In one step they nearly doubled the number of known histone marks, and that's before you start looking at variant histones.

@Jackson (#32). Being an old argument does not make it wrong. While I don't mind being tarred with the brush you use on biologists or theorists, I am actually a synthetic organic chemist by training who got my PhD working on large macrolides and I still work in the lab today. (Though certainly not as much as I did in grad school.)
Like cliffintokyo (#34), I don't see how things are much advanced by these two papers. The fact that Wender and Krische used Keck's chemistry to make some of their analogs is a much better vindication of Keck's chemistry than his own efforts to find something useful to do with it. Likewise, Krische's work has already shown its utility and this synthesis, as you point out, doesn't showcase it very well.
So, best papers of 2011? I don't agree. We didn't really even learn anything new about polyketide synthesis or macrolide synthesis from these papers. We didn't learn more about bryostatin. I think all we learned is that, while the argument may be old, we need to keep having it.
#35: If it was so obvious and incremental, why isn't anyone else doing it? The total synthesis papers aren't that exciting, but Krische's methodology is useful. I need to see his methodology papers much more than I need to see yet another organocatalytic enantioselective prepn. of spiroindolones.
Making the bryostatins is neat, and the incremental refinements might help to find an effective analog in the future, but they probably aren't going to do a whole lot for anyone in the near term, and the syntheses weren't jaw-droppingly awesome.

I never said (nor meant to imply) that any of the Bryostatin synthesis papers should qualify as "best paper of the year". I never would have brought them up in that context. I was just responding to some comments from others. While I believe the endeavors are admirable, and the chemistry which was developed in their pursuit is creative and useful, I agree that none are going to shake the foundations of science and bring Derek to his knees weeping uncontrollably.
Hap...see the context..
Best paper in 2011...and somebody comes up with KRische from the ENTIRE chemistry and biology literature.
And the paper conatins (lets say borrows too heavily) from the previous synthesis.
Now , if you are a real scientist and objectivity is your standpoint, do you see the point now?
Seriosly , now we have fawner(s)

Nobody , who matters, cares.
On the one hand we have someone suggesting that if work is obvious and incremental then it would have been done (this comment comes as a response to the (allegedly obvious and incremental) work actually having been done); which implies that the commenter believes that the community is doing - not necessarily should be doing, but is doing nevertheless - obvious and incremental work. Which is probably true, whatever one might think about what they (we?) should be doing.
I kind of think I touched a lot of raw nerves there
with the whole Krische group going bonkers on me with names like 'Ir II' , 'Useless Molecule'.
Hey, I am just complaining abt it being labelled
best paper.Thats all, guys!

You are certainly entitled to your opinions. Like the saying goes, everybody's got one... But to make (or agree with) the statement "nobody, who matters, cares" is both ignorant and very arrogant. You are essentially implying that 'nobody, who cares, matters'. If that's true, then it not only applies to Krische, but also Corey, Evans, Nicolaou, Danishefsky, etc. I think you would find Big Pharma populated with MANY people who would disagree with you.
By the way, I'm not a "fawner", nor am I here to defend Krische's work. I'm just here to wish you a Merry Christmas, and a very INTERESTING New Year. May you receive the perspective you need and deserve.

Its the bitter truth.I do not know with what intent it was said but its the bitter truth.In the posts above many ppl have expressed such sentiments, Hap said 'we dont need another synthesis of spiroindolones', some ppl hv expressed similar sentiments about macrolids, biku has the same opinion abt Krische's work.But its expressing different faces of the truth that synthesis is not as important as it once was when Corey, Nicolau Evans, Danishefsky ruled.Societies need and priorities change and is reflected in different ways of expression. I hope its not taken as a personal attack as I have seen that the opinions/dreams I had about synthesis when I was in graduate school has been drastically altered with the harsh realities of employment I faced.
happy holidays to everybody.

The bitter truth is in the eye of the bitter beholder. Do be bitter bro. I understand your opinion. And while my opinion is that organic synthesis is as important today as it ever was, I don't know of any synthetic papers this year that should be mentioned under the heading of this string (though I'm still open for suggestions). That said, deciding what is scientifically important (or important in life in general) based on "harsh realities of employment" or even "societies (immediate) needs and priorities" is short sided indeed. Yes, having money to pay the rent is damn important personally, but honestly, Biku and Useless couldn't give a crap about you or your rent. Another bitter truth.
As an aside... I don't know the numbers on this or how to go about getting an accurate estimate, but I would guess that there is as much or more synthetic organic chemistry going on today (R&D and Manufac) as there ever was -- it's just that a lot of it is getting done in Chindia. So maybe you should put the blame for your altered career path where it really belongs, though that my bitter friend would take us down another unpleasant road.
54. provocateur on December 23, 2011 5:53 PM writes...
I think whatever I said can be proven by how much
money the science of synthesis gets by way of federal money since almost all synthesis is funded that way.It has decreased considerably and beyond the committees that decide who shd get what and how much, the share of the pie has decreased considerably.Money is there for newer , green methods like for Krische and thats why he is never interested in a 'full' demonstration of his methodology in bryostatin synthesis.He just wants to demonstrate 'usefulness' by doing partial synthesis.Organic synthesis is important but in a 'bio-context'.You get sneered at if you want to use thallium or tin reagents.So the 'society;s'
expectations have increased.And thats why I said
organic synthesis 'as practiced' is no more imp.
I am not bitter becos after grad school I understand the world better and in a different context.The closed shell structure of grad school
can make you ignorant of the world outside.
How many ppl here would like their children to become chemists?nothing bitter but just getting real.
A little late in the game for an entry, but if the 6 Dec PNAS ( vol. 108 pp. 19784 - 19789 '11 6 Dec issue) actually holds up. It certainly would be a great Christmas present for the many people suffering chronic pain. They describe a naltrexone derivative which, unlike the parent compound, has analgesic activity 10x more potent than morphine, but which lacks (1) respiratory depression (2) physical dependence (3) reinforcement activity -- animals won't work to get it. The work is in mice. For details see the paper, or https://luysii.wordpress.com/2011/12/23/a-christmas-gift-for-all-of-us-if-it-holds-up/

So, best papers of 2011? I don't agree. We didn't really even learn anything new about polyketide synthesis or macrolide synthesis from these papers. We didn't learn more about bryostatin. I think all we learned is that, while the argument may be old, we need to keep having it.

Sorry, #38 was me. Even if it's a pseudonym, I figure I should own up to it.

#35: If it was so obvious and incremental, why isn't anyone else doing it? The total synthesis papers aren't that exciting, but Krische's methodology is useful. I need to see his methodology papers much more than I need to see yet another organocatalytic enantioselective prepn. of spiroindolones.
Making the bryostatins is neat, and the incremental refinements might help to find an effective analog in the future, but they probably aren't going to do a whole lot for anyone in the near term, and the syntheses weren't jaw-droppingly awesome.

Permalink to CommentI never said (nor meant to imply) that any of the Bryostatin synthesis papers should qualify as "best paper of the year". I never would have brought them up in that context. I was just responding to some comments from others. While I believe the endeavors are admirable, and the chemistry which was developed in their pursuit is creative and useful, I agree that none are going to shake the foundations of science and bring Derek to his knees weeping uncontrollably.

Hap...see the context..
Permalink to CommentBest paper in 2011...and somebody comes up with KRische from the ENTIRE chemistry and biology literature.
And the paper conatins (lets say borrows too heavily) from the previous synthesis.
Now , if you are a real scientist and objectivity is your standpoint, do you see the point now?
Seriosly , now we have fawner(s)

On the one hand we have someone suggesting that if work is obvious and incremental then it would have been done (this comment comes as a response to the (allegedly obvious and incremental) work actually having been done); which implies that the commenter believes that the community is doing - not necessarily should be doing, but is doing nevertheless - obvious and incremental work. Which is probably true, whatever one might think about what they (we?) should be doing.
There is no other hand.

Biku, Usless, Provo, etc.
You are certainly entitled to your opinions. Like the saying goes, everybody's got one... But to make (or agree with) the statement "nobody, who matters, cares" is both ignorant and very arrogant. You are essentially implying that 'nobody, who cares, matters'. If that's true, then it not only applies to Krische, but also Corey, Evans, Nicolaou, Danishefsky, etc. I think you would find Big Pharma populated with MANY people who would disagree with you.
By the way, I'm not a "fawner", nor am I here to defend Krische's work. I'm just here to wish you a Merry Christmas, and a very INTERESTING New Year. May you receive the perspective you need and deserve.

Permalink to CommentIts the bitter truth.I do not know with what intent it was said but its the bitter truth.In the posts above many ppl have expressed such sentiments, Hap said 'we dont need another synthesis of spiroindolones', some ppl hv expressed similar sentiments about macrolids, biku has the same opinion abt Krische's work.But its expressing different faces of the truth that synthesis is not as important as it once was when Corey, Nicolau Evans, Danishefsky ruled.Societies need and priorities change and is reflected in different ways of expression. I hope its not taken as a personal attack as I have seen that the opinions/dreams I had about synthesis when I was in graduate school has been drastically altered with the harsh realities of employment I faced.
happy holidays to everybody.

The bitter truth is in the eye of the bitter beholder. Do be bitter bro. I understand your opinion. And while my opinion is that organic synthesis is as important today as it ever was, I don't know of any synthetic papers this year that should be mentioned under the heading of this string (though I'm still open for suggestions). That said, deciding what is scientifically important (or important in life in general) based on "harsh realities of employment" or even "societies (immediate) needs and priorities" is short sided indeed. Yes, having money to pay the rent is damn important personally, but honestly, Biku and Useless couldn't give a crap about you or your rent. Another bitter truth.
As an aside... I don't know the numbers on this or how to go about getting an accurate estimate, but I would guess that there is as much or more synthetic organic chemistry going on today (R&D and Manufac) as there ever was -- it's just that a lot of it is getting done in Chindia. So maybe you should put the blame for your altered career path where it really belongs, though that my bitter friend would take us down another unpleasant road.

I think whatever I said can be proven by how much
Permalink to Commentmoney the science of synthesis gets by way of federal money since almost all synthesis is funded that way.It has decreased considerably and beyond the committees that decide who shd get what and how much, the share of the pie has decreased considerably.Money is there for newer , green methods like for Krische and thats why he is never interested in a 'full' demonstration of his methodology in bryostatin synthesis.He just wants to demonstrate 'usefulness' by doing partial synthesis.Organic synthesis is important but in a 'bio-context'.You get sneered at if you want to use thallium or tin reagents.So the 'society;s'
expectations have increased.And thats why I said
organic synthesis 'as practiced' is no more imp.
I am not bitter becos after grad school I understand the world better and in a different context.The closed shell structure of grad school
can make you ignorant of the world outside.
How many ppl here would like their children to become chemists?nothing bitter but just getting real.

A little late in the game for an entry, but if the 6 Dec PNAS ( vol. 108 pp. 19784 - 19789 '11 6 Dec issue) actually holds up. It certainly would be a great Christmas present for the many people suffering chronic pain. They describe a naltrexone derivative which, unlike the parent compound, has analgesic activity 10x more potent than morphine, but which lacks (1) respiratory depression (2) physical dependence (3) reinforcement activity -- animals won't work to get it. The work is in mice. For details see the paper, or https://luysii.wordpress.com/2011/12/23/a-christmas-gift-for-all-of-us-if-it-holds-up/
