Notes on crystal binding proteins

Saturday, October 9th, 2010

I’ve had trouble finding info. A google search on “crystal binding proteins” sorta worked.

IgA binds to cholesterol crystals:
Cholesterol crystal binding of biliary immunoglobulin A: visualization by fluorescence light microscopy. Lammert et al. World J Gastroenterol. 2001 Apr;7(2):198-202.

There no doubt are proteins that bind to calcium carbonate shells material, but I couldn’t find info on them. I think shell is formed like bone, by cells increasing the local concentration of Ca++ so it crystallizes out of solution rather than by direct enzymatic action.

Extra-science news

Saturday, October 2nd, 2010

I would like a source for science news articles that actually has the science. Biology articles that include gene names and what a study actually found. Stories that describe things with the correct technical terms, not ‘the internet is like a series of tubes’. News stories written at an old-time Scientific American level, at the level of medical or graduate school alumni magazines. Stories that link to the journal article, to the institution or lab’s page, the patent, that link to Wikipedia or a relevant site for background.

What I would really like a source that linked standard news accounts of science to an extra-science version of the news. This site could write the extra-science article, but no need for redundancy–if some other site has an account with the relevant details then this site would just link to it. ars technica’s Nobel Intent science news site often does the job, but of course they only cover some of the news and don’t provide the nexus–linking the weak tea news stories to their articles.

The nexus should facilitate the connection. Allow the user to enter the news site URL, story title, or a sentence of text and recognize the story and link to the extra-science article. Standard keyword searching would be useful as well. The Reeves lab had an almost perfect example of the empty science news story taped up: ‘Scientists clone brain gene. This discovery will lead to an understanding of how the brain works.’
