7:28 AM | DNA sequencing reaches new lengths
Sequencing technologies have made it cheaper and faster to read the sequence of bases on a strand of DNA. A promising technology to take these advances further is nanopore sequencing. Individual strands of DNA are moved through a nanopore gap not much wider than the DNA itself. As the DNA passes through the nanopore, continuous information is gained about the sequence of individual bases - the A, C, G and Ts that make up DNA. Researchers now have developed a nanopore sequencing technique […]

9:15 PM | CSB: No preventative maintenance at Freedom Industries
In March, I said this about the leaking tanks that caused the huge MCHM mess outside Charleston, WV:Freedom Industries is likely responsible for the apparent poor state of their tanks -- I wonder if those tanks have ever been pressure checked or what the preventative maintenance logs look like. And now, thanks to the Chemical Safety Board, we have some answers (emphasis mine): ...the U.S. Chemical Safety Board (CSB) reported today it has thus far found no record of a formal, […]

5:28 PM | Blue Blood Donors
In the first half of the 20th century, scientists faced a vexing  problem. Too many people were being sickened and killed by bacterial endotoxin—a substance in a bacteria’s outer membrane toxic to animals and resistant to heat—contracted through vaccines and surgery tools. The only way to determine if something was contaminated was to test it on animals, a slow and expensive process. In 1956 a scientist named Fred Bang was studying the blood circulation in horseshoe […]

3:51 PM | Too funny, too true
I'm enjoying the new chemistry blog C&EN Onion -- they're a lot funnier than I am these days. I hope they keep it up:Congress: NIH Funding To Be Distributed Via Cage Fighting(Washington, D.C.) In a rare showing of strong bi-partisan support, landmark bill S. 2651 entitled the "Investigational Combatant Funding Reappropriation Act" has passed through the United States Senate and been signed into law by President Obama.  "My fellow Americans, today marks an important milestone in our […]

1:15 PM | Thalidomide’s molecular actions revealed
Once shunned for causing severe birth defects in babies, thalidomide has made a comeback to treat some blood cancers and leprosy. In a paper now out in Nature, researchers describe the crystal structure of the drug bound to its target. From their data, the researchers provide an explanation how this drug can either save or […]

10:10 AM | 5 Uses of Sodium Hypochlorite
The most common use for Sodium chlorite (NaClO) may be as bleach, but it is certainly not the only one. Other examples include cleaning water and disinfection for the treatment of eczema, to name just a few.  How is it produced? In 1789, Claude Berthollet was the first to synthesise potassium chloride (KClO) by mixing potash [...]

2:05 AM | A response to recent events
The re-post of my Feynman post on SciAm and the note attached to it have led me to write this response. Several readers have asked me what happened, so I will endeavor to clear the air and provide what I consider to be a complete story from my perspective. Folks are welcome to comment and criticize any of the actors involved in the story. One reason I am writing this is because I think it raises several issues that are at the heart of blogging in the age of social media and under the […]

1:44 PM | An Unlikely Combination: Thiol-Ene Chemistry and Isocyanate-Free Polyurethanes
Long-time readers of this blog may recall that I spent a good deal of time with my previous employer working with thiol-ene chemistry. I really loved working with that chemistry - it was very fast and versatile, although my wife never enjoyed the experience of handling my cloths at the end of the day. Upon changing jobs a year and a half ago, I've set those malodorous chemicals aside and moved on to other monomers. These new monomers are apparently lightly scented, but I always question why […]

9:24 AM | Is it Time for Fake Tan?
On one of our recent blogs, we looked at the chemistry of the sun. However, we all know how too much of it can be dangerous, which means a natural tan without the aid of any products is totally out of the question. If you’re looking for “the look” (more importantly without risking your health), [...]
