3:32 PM | "Home" or something like it
Sports fan (and chemist) Denny has a really insightful (and amusing) set of comments about the return of LeBron James to Cleveland: ...Which brings us to Ohio: I have not lived in Ohio since 2006. I do not plan to live in Ohio any time in the near or distant future, nor do I particularly want to raise my child there. But Ohio is still important to me because I am from there, and I very much want for Ohio to thrive. I think that’s where a lot of my initial excitement about […]

3:07 PM | Do you want to publish for free in PeerJ?
I started following the Open Access movement ca. 2 yrs ago, mostly through the blogs of Michael Eisen, Jan Jensen and Mike Taylor. I was obvioulsy well aware of the successful OA outfits, like PLOS and BiomedCentral, but had never considered publishing there due to the shortage of funds and the non-reimbursability of such expenses by my country's Science Foundation. I joined PeerJ shortly after they "opened for business", due to their their very small fees and because of commitment to […]

2:34 PM | Using the telephone for job-searching
I really like this guide to the use of the telephone for job searching over at Science Careers, if only for this advice: If you’re like most people, you’ve got at least two phones, a home phone and a cell phone. You may have your own business phone, too, and for reasons I haven’t yet plumbed, some people seem to have more than one cell phone. Some people use a cell phone as their sole telephony instrument. That’s OK, but it’s not ideal. Business calls are […]

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 […]

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 […]
