9:45 PM | About the Benefits of Lemon Water that You may/may not Have Heard Of
When we think of lemons, or citrus fruits in general we think of vitamin C. In fact lemons are packed with more than just vitamin C; they are crammed with vitamin C, B-complex vitamins, calcium, iron, magnesium, potassium, and fibre. I have heard a lot about lemon water and how it’s good for you and great for your digestion. Obviously I wanted to research and find out more about lemon water. Little did I know just how many benefits there are!Preparing Lemon WaterBecause lemon juice […]

6:04 PM | Sins in science - poor disclosure
Back again. My wife died on the 16th of January, so my blogging will be a bit erratic for a while, but at the end of last year I had planned some, and one theme included the behavior of the scientific community in the dissemination and discovery of knowledge, so here is the first blog that was written before this unfortunate event.   In a recent essay in Angew. Chem. Int Ed. 52: 118 – 122, van Gunsteren outlined what he considered the seven sins in academic behavior, which he ordered […]

4:34 PM | Interesting call for archiving by Jeff Seeman
Also from this week's C&EN, a letter to the editor from chemical historial Jeff Seeman:The insightful article by Linda Wang titled “Turning Off the Lights” focuses on the difficult process, physically and emotionally, for faculty to close down their laboratories (C&EN, Sept. 8, 2014, page 50). One newly minted emeritus faculty member, Al Padwa of Emory University, describes how “there are some things he just can’t bring himself to throw away yet . . . old photos […]

4:26 PM | This week's C&EN
Lots of good stuff in this week's C&EN:I did not expect to be as interested as I am in this Michael McCoy article about cleaning solvents. Really interesting stuff there. (Say, is 7000 tons of agricultural waste a lot? Something tells me "no, not at all.")Interesting to see less-than-lightning-fast uptake of hydraulic fracturing in China. (article by Bree Fang)Lisa Jarvis reports from the J.P. Morgan biotech conference; interesting to hear the classic "are we in a bubble?" talk at the […]

4:00 PM | Last week's C&EN
Some interesting things in last week's C&EN:Thought it was very interesting that (new editor-in-chief) Bibiana Campos Seijo shared her thoughts on that "gatekeeping" article that we all were discussing a couple weeks back. (Excited to see what her favorite topic will become.) Pretty fun infographic by Andy Brunning on chemical deicers.I thought this article by Britt Erickson on inert ingredients in pesticides is one that chemists should try to understand a little better (i.e. […]

2:23 PM | Mobile computing technology usage – early 2015 update
This is an update on my usage of mobile computing technology as of January 2015. During 2014 I came to the conclusion that, good as they are, Android tablets won’t ‘cut the mustard’ for power users like myself, at least as far as using Microsoft software is concerned. There are plenty of good MS Office … Continue reading Mobile computing technology usage – early 2015 update →

3:51 PM | A Science Journalist Ventures Into the Lab
Guest Post by Zachary Vasile It can be difficult to record exactly how a writer thinks. This is not to mystify the brain of a writer, but to say that we often reason in incredibly convoluted and abstract ways, leaping from one thing to another, working in undisciplined bursts when the spirit takes us. And […]

2:29 PM | BPA and BPS
As much as I would like to brag, or say "I told you so", I really don't feel that I'm prescient in the least. Any scientist with a little appreciation for their field would instantly recognize that when somebody says "Chemical X is poisonous! We need to stop using it!", the immediate follow-up questions should be:OK, so what should we replace it with?andWhy do you think the replacement is any better?And yet that is what we face with the chemical bisphenol A, also known as BPA. It is the […]

Q: RNA-containing ‘stress granules’ play a key role in the response to stresses such as viral infection and oxidative stress in mammalian cells. Describe these granules and how they might be relevant to human disease. Q: Compare and contrast stress granules and P-bodies in terms of their constituents, mechanism of formation and role in human disease. Above: Drosophila P bodies, from Eulalio 2007 Stress impacts the fate of mRNAs in various ways. RNA containing granules are involved […]
