Some of my fellow bloggers and I have been following the fall out from an Op Ed piece in the Washington Post on the NSTA’s refusal to mail 50,000 copies of the “An Inconvient Truth” DVD to it’s members. You can read earlier posts: here, here, and here. Today, the NSTA confirmed that they never…

The EMBL graduate students have organized an ingenious conference titled: Life Sciences – Shaping the Future. Learn about Omics and Systems Biology from speakers like Leroy Hood, Stuart Kim, and Ronald Krause (and more). Explore options for career development, and learn how you can join the Web 2.0 science revolution in the session on scientific…

What’s the difference between a synthetic drug and an antibiotic? Sometimes there’s no difference at all. Let’s take a look at chloramphenicol and couple of pencillins.

One of my favorite books, “The Phantom Tollbooth,” by Norton Juster, has a wonderful description of the penalties for making decisions without carefully evaluating the facts. Whenever the characters in the book arrive at a decision too quickly, they end up, literally, “jumping to Conclusions,” an island far off the shore. The penalty for quick…

Antibiotics are molecules of biological warfare. Produced by bacteria and some fungi, in response to extracellular signals, antibiotics represent a diverse group of compounds that inhibit bacterial growth at different points and different stages of the life cycle. We will get around to antibiotic resistance, but in these few words, I think I already wrote…

A few years ago, I heard an interesting thing from another mother when I picked my oldest daughter up from daycare. The other mother was suffering from a head cold and confessed to me her fear that she had become “antibiotic resistant.” I found this statement pretty funny at the time, especially since I was…

Fellow SciBlings Tara Smith (here & here), Mike Dunford (here & here), GrrlScientist, and I…

Bloggers, Ron Hudson from the International Carnival of Pozivities will be putting together stories about AIDS and HIV. The next carnival isn’t until Dec. 10th,…

Parasites and Purity

A few weeks ago, I wrote about visiting the Dead Sea Scrolls exhibit at the Pacific Science Center and learning how DNA analysis is being used to help put pieces of the scrolls together. One of the mysteries that was discussed in the exhibit was the question of whether the members of the religous sect…

I touched a nerve in another post by mentioning molecular biology kits. Let’s face it. Cloning kits, sequencing kits, and their relatives are the laboratory equivalent of frozen cookie dough.
