    Checking The Numbers on the Alzheimer’s Test

    The news of a possible diagnostic test for Alzheimer’s disease is very interesting, although there’s always room to wonder about the utility of a diagnosis of a disease for which there is little effective therapy. The sample size for this study is smaller than I’d like to see, but the protein markers that they’re finding… Read More

    Let Us Now Turn To the Example of Yo’ Mama

    Now we open the sedate, learned pages of Nature Methods, a fine journal that specializes in new techniques in molecular and chemical biology. In the August issue, the correspondence section features. . .well, a testy response to a paper that appeared last year in Nature Methods. “Experimental challenge to a ‘rigorous’ BRET analysis of GPCR… Read More

    More Things Than Are Dreamt Of

    It’s useful to be reminded every so often of how much you don’t know. There’s a new paper in PNAS that’ll do that for a number of its readers. The authors report a new protein, one of the iron-sulfur binding ones. There are quite a few of these known already, so this wouldn’t be big… Read More

    Visfatin: Real Or Not?

    A commentor to my Proteomics 101 post the other day brought up an important point: that before you can have a chance to figure out what a protein is doing, you have to know that it exists. Finding the darn things is no small job, since you’re digging through piles of chemically similar stuff to… Read More

    It Went Up Instead of Down

    One of the things I like most about science is that you really don’t know what’s going to happen next. That’s especially true in the areas where things have just barely settled down. Before that, when a field is new, no one knows what to expect, so in a way there aren’t really any surprising… Read More

    Peptides as Texts

    There’s a curious paper (subscriber-only link) in the latest Nature that’s getting some attention, titled “A linguistic model for the rational design of antimicrobial peptides”. For non-subscribers, here’s a synopsis of the work from the magazine’s news site. A group at MIT headed by Gregory Stephanopolous has be… Read More

    Neowater Replies

    I received (some time ago) an answer from Miguel Cizin and the folks at Docoop, makers of Neowater. (If you haven’t seen the first parts of this story, they’re here and here). In that last post, I had a number of look-under-the-hood physical chemistry questions about the stuff, in an attempt to figure out if… Read More

    Nanotech Wonder Water?

    Genetic Engineering News is sort of an odd publication. Primarily a vehicle for big, glossy color ads, it publishes some articles of its own: guest editorials, roundups of news from conferences and trade shows, that sort of thing. And it also publishes plenty of things that are (that have to be) slightly rewritten press releases… Read More

    Stem Cell Disaster

    Update: Since the site was down most of Tuesday, I’m leaving this post up another day. Things have only worsened since I put it up, though. . . I’ve been withholding my comments on the South Korean stem cell controversy, waiting to see how the story finally settled out. Well, it’s good and settled now: Read More
