9:48 AM | Buckyballs and diamondoids join forces in nanoelectronics
Researchers have married two unconventional forms of carbon to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.

9:16 PM | Who gave Bill Gates his C+ in organic chemistry?
The long policy article of the weekend was probably the New York Times Magazine article on Bill Gates' desire for an integrated history course. I think it is pretty awesome that he admits to a C+ plus in organic chemistry.So who taught Gates organic chemistry? It would probably have been between 1973 and 1975 or so... Was it the Fiesers?(Substantively, I don't think the article addresses what I want to know, which is "What has been the history of teaching world history? How does Gates' […]

7:10 PM | A Brief Overview of Classes of Antibiotics
When we’re suffering from a bacterial infection, a trip to the doctors to be prescribed antibiotics is commonplace. However, there are a wide range of antibiotics available, and they vary both in their usage and their mechanism of action. This graphic summarises the major classes, and also gives a brief insight into the manner in which they […]

4:21 PM | Update on NH Synthetic Cannabinoid Illnesses - July/August 2014
As covered previously, the state of New Hampshire issued a state of emergency regarding an outbreak of illnesses and hospitalizations surrounding a synthetic cannabinoid-containing bubblegum flavored product named "Smacked!" In my last blog post about this topic, we covered why it may take so long to release this type of information (chain of custody, instrumental analysis, QC, goverment-lab workflow, this ain't CSI, etc.)According to a release (dated August 22, 2014) by the New Hampshire […]

2:00 PM | Update: Greenwashing 7 - Simple Green
Way back when I followed a CBC Marketplace show and assessed their assessment of the products, I mentioned that I should buy and try one of them: Simple Green. Well, I did, and I forgot to post an update. So, here it is. I tried it out on a stubborn dirty spot that both "Scrub Free" and "Fantastik" barely touched, even with a lot of scrubbing. I followed the directions on the bottle: for tough

1:17 PM | First-ever look inside a working lithium-ion battery (w/video)
In an unprecedented view inside a working lithium-ion battery, researchers used a neutron beam to 'see' lithium flow as the battery charged and discharged. The study could one day help explain why rechargeable batteries lose capacity over time, and sometimes even catch fire.

1:09 PM | A low-energy optical circuit for a new era of technology
Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists have developed a first building-block for photonic 'transistors' that requires record-low energy to operate. The device is a big step forward in the development and implementation of optical circuits.

10:54 AM | Making good on my "Open Access" pledge
My most recent paper has just been published in PeerJ . It was a LONG time in the making, to the point that my 12-yo daughter once told me (only half-in-jest), that I should "cut my losses and forget about it". I am quite happy about how it turned out: besides describing an analysis of a reaction mechanism and the influence of the redox state of a hard-to-converge Fe-S cluster , it also contains  the first computations including the weighed contributions of 1.2*1013 protonations states of […]
