I like reading the stuff on Science Daily, blogs like Cooling Inflammation, Hyperlipid and Whole Health Source and the occasional book from Amazon. I search PubMed and other sources to find out info or learn new stuff sometimes too.

Apart from books, which tend to be quite watered down, I don't have any Japanese sources like the ones above. I tried finding a Science Daily equivalent, but could only find sites with a tiny science section that rarely had areas I'm interested in. Does anyone read any good blogs on science, health, nutrition etc? Is there something like PubMed or a journal with free articles like Nature (some of the reviews read like a chapter from a good book).

I wanted to write a lang-8 entry about some mind-controlling parasites I was reading about, but realised my vocab is too shite to do it smoothly. I don't think it's so much needing a lot of new words as just seeing how people express this stuff in Japanese. Wikipedia tends to be boring...

Probably too watered down for your tastes, but I think Wired has a Japanese version. Sometimes they write about sciency stuff.

edit: There's also slashdot.jp. If I remember correctly, there is a specific "science" section (i.e. sciency things that are not computer-related).

Well, probably not exactly what you have been looking for, but if you search for scientific stuff on the pages linked to below, you may find some really interesting articles I believe.

Thanks for the suggestions. I'll take a look.
