DNA walker

[edit]
(
)

Moved to mainspace by Ashaul3 (talk). Nominated by Antony-22 (talk) at 06:45, 13 December 2015 (UTC).

  • Begin Review... long enough, moved to mainspace within 5 days of nomination, so counts for creation. QPQ done by nominator. Earwig's copyright detector points to some paraphrasing issues:

Article: ... are made from DNA-coated spherical particles that hybridize to a surface modified with complementary RNA. Motion is achieved through the addition of RNase H, which selectively hydrolyses the hybridized RNA ...

Online Source: ... are made from DNA-coated spherical particles that hybridize to a surface modified with complementary RNA; the motion is achieved through the addition of RNase H, which selectively hydrolyses the hybridized RNA ... - This appears to be lifted from the abstract of a journal article

  • Hook fact is in the lede without a direct citation, but it is cited in the body. References do not have doi's (unfortunately), though none are simple urls so are allowed under DYK. Sources themselves are fine and used throughout - but are there other plagiarism issues from these sources?
General: Article is new enough and long enough

Policy compliance:

Hook eligibility:

  • Cited: No - I would like to see a single source used for the claim in the lede and the article, then I can check it properly
  • Interesting: No - I think it is interesting, but am not sure about wide appeal. The idea of a machine traveling along DNA at a molecular level has enormous potential, but would that be obvious to a non-scientist? Will reconsider when I can check the reference properly.

Image eligibility:

QPQ: Done.

Overall: I can't give this a "minor changes" because of the plagiarism issue, and spot checks on journal sources are needed given lifting from an abstract is established. EdChem (talk) 07:57, 29 December 2015 (UTC)

I've cleaned up the mentioned copy-paste, and added dois to make further copy-paste detection easier. Antony–22 (talk⁄contribs) 23:17, 29 December 2015 (UTC)
  • ALT1 ... that DNA walkers are potentially feasible machines for detecting heavy-metal contamination in water?
  • New reviewer needed to check the newly proposed ALT1 hook and check to be sure the previously identified issues have been satisfactorily addresed. BlueMoonset (talk) 18:10, 24 January 2016 (UTC)

General eligibility:

Policy: Article is sourced, neutral, and free of copyright problems

Hook eligibility:

  • Cited: No - The source does not match up with what the article and hook are saying. The source says it's low cost and it does say it can sense heavy metals in water, but whether this is a potentially feasible method seems to be original research.
  • Interesting: No - Original hook is not interesting. ALT1 is.
QPQ: Done.

Overall: It was nominated too late. Other editors feel free wavering this, but the issue with the hook would still need to be fixed. Jolly Ω Janner 05:37, 26 January 2016 (UTC)

Tradition is that we're not stingy about the nomination deadline; hopefully this is close enough. I'm not sure why the original hook is uninteresting, but here's another one... Antony–22 (talk⁄contribs) 17:56, 26 January 2016 (UTC)
  • I can't agree that the original hook is uninteresting—it was that hook that just encouraged me to read the article. IMO it is more hooky than the alternatives proposed. I also support waiving the newness requirement. The article author is very new and only just missed the deadline by a day and a half. SpinningSpark 15:13, 28 January 2016 (UTC)
  • @Antony–22: Now that I think more about it, I think the original hook may be interesting. Maybe I was reading EdChem's comment too much. Anyway, all the hooks are supported in the article and have inline citations at the end of the sentence. I would like to check it in the sources though. Is there any chance you can point me in the right direction, as the sources are a bit tedious to navigate, and I'd rather avoid having to read all of them. Just something I can plug into my browser's search tool to bring up where abouts it is will do. Thanks. Jolly Ω Janner 09:11, 29 January 2016 (UTC)
For molecular cargo and organic synthesis, third-to-last sentence of "Role in DNA nanotechnology". For the heavy metal sensor, last sentence of "Applications". These are all easily apparent from reading the article, and both actually did have the citations at the end of the sentence. Antony–22 (talk⁄contribs) 01:03, 31 January 2016 (UTC)
@Antony-22: I would like know the location in the source, not the article. Thanks. Jolly Ω Janner 01:11, 31 January 2016 (UTC)
For molecular cargo and organic synthesis, just read the abstracts. For the heavy metal sensor, Esemono has already copied it above. Antony–22 (talk⁄contribs) 01:25, 31 January 2016 (UTC)
I was trying to find the fact in the rather hefty abstract from Lund, but it was in the much shorter abstract from Gu. I'm striking the alternatives as I find the original interesting. This is ready to go. Jolly Ω Janner 02:26, 31 January 2016 (UTC)
