On pinene and inhibiting enzymes. People of a certain age may remember a series of really funny commercials featuring Euell Gibbons and his famous question about whether you’ve ever eaten a pine tree.  “Some parts are edible” said Euell. Perhaps some parts are, but other pine tree products aren’t so nourishing.  Crystallography365, aka @Crystal_in_city  had a couple of…

It’s a long, long, weekend; perfect for going outside and doing a few loud, messy experiments. Cooking-intensive holidays always remind me how much fun it is to do a bit of chemistry, especially when it comes to food. If you watched the video that I posted on Thanksgiving, you’ve probably been itching to try one…

If you’re not cooking today, why not experiment? Here’s something fun you can do with Mentos and Diet Coke – and for those of you who think these experiments are too messy, you can still watch the movie. Enjoy the music in the video, then go outside, and enjoy the show. Later, go to EepyBird.com…

Our household is very excited about Thanksgiving. That’s because this Thanksgiving, my husband is cooking a turkey in an egg. A big green egg. Check back later today, about 5:30 pm, Pacific Standard Time, to see a picture of the turkey. In the meantime, here are some other items that were cooked in the egg.

Before mammals, before dinosaurs, before bacteria, or plants, there was something else; a protocell containing RNA. The Exploring Origins Project has excellent animations of protocells, a timeline of life’s evolution, and best of all- fantastic animations of the RNA world. You can see how RNA folds, ribozymes (RNA that catalyzes chemical reactions), and learn about…

Want to learn more about Parkinson’s disease? See why a single nucleotide mutation messes up the function of a protein? I have a short activity that uses Cn3D (a molecular viewing program from the NCBI) to look at a protein that seems to be involved in a rare form of Parkinson’s disease and I could…

The Periodic Table of Videos from the University of Nottingham has 118 short YouTube clips about the elements. Wired Campus recommended the Sodium clip (below). I liked it, too. It’s not quite as funny as Mentos in Diet Coke, and but it’s still cute and the narrator has a haircut like Gene Wilder in Young…

Instead of enjoying a sunny summer day today, or partying with SciBlings in New York, I’m staring out my window watching the rain. Inspiration hit! What about searching for August? Folks, meet the HFQ protein from E. coli. I found this lovely molecule by doing a multi-database search at the NCBI with the term ‘August‘.

APRIL was so much fun, that I thought I should find a molecule for May. I searched both the Gene database, the structure database, everywhere, without any luck. Finally, I decided to change the search and use the date instead of the name of the month. And here we have it, straight from PubChem. A…

Over 2600 genetic diseases have been found where a change in a single gene is linked to the disease. One of the questions we might ask is how those mutations change the shape and possibly the function of a protein? If the structures of the mutant and wild type (normal) proteins have been solved, NCBI…
