3:56 PM | An Ironic Effort from Greenpeace
Here's today's newest example of irony:Greenpeace succeeded in pressuring Lego into cancelling a toy give away with Shell. (Fill up with at least 30 liters and get a free Lego toy). Greenpeace was going after Shell because of Shell's efforts to extract oil from Arctic regions, but the irony is that Lego toys are all made from petroleum-based plastic (ABS). So does this change anything? Anything?Previous YearsOctober 9, 2013 - Preventing Oxygen Inhibition during PolymerizationsOctober 9, 2012 -

11:29 AM | What is a Chemical Element? [part 1]
The most modern version of chemical element defines these entities as pure substances made up of only a single type of atom distinguished from other elements by their individual atomic number. So, for example hydrogen (H) is an element, but water (H2O) isn’t. Elements can be sub-divided into metals, nonmetals and metalloids, each with very [...]

5:26 PM | The 2014 Nobel prize for Chemistry: Super-resolution microscopy
Two separate principles are rewarded. One enables the method stimulated emission depletion (STED) microscopy, developed by Stefan Hell in 2000. Two laser beams are utilized; one stimulates fluorescent molecules to glow, another cancels out all fluorescence except for that in a nanometre-sized volume. Scanning over the sample, nanometre for nanometre, yields an image with a resolution better than Abbe’s stipulated limit. Eric Betzig and William Moerner, working separately, laid the […]

4:47 PM | More later, but some Wednesday fun
This UC-Irvine parody of the song "Let It Go" (the bane of fathers of children of a certain age, everywhere) is pretty great. I'm fairly resistant to watching funny videos, but I laughed at least twice.

What do fossilized whales and beer have in common? According to an article and a video by NPR, they both contain yeast. Amateur paleontologist Jason Osbourne scraped a living subspecies of yeast from whale bones he found in a Virginia swamp with the help of microbiologist Jasper Ackerbloom. They used the yeast to brew what they call Bone Dusters Paleo Ale. The yeast itself probably came from the swamp and is not as ancient as the 35-million year old fossilized proto-whale. You might remember […]

1:18 PM | "Let's Get Rid of the Mole"
Being called one-dimensional is usually not a good thing. But a recent letter to the editor published in C & E News (hat tip to Chemjobber) is proposing that we all take one step closer to that state by getting rid of the mole, the counting unit used in chemistry. The proposed alternative is we use the yotta (= 1024) instead since it is pretty close to Avogadro's number (6.022 x 1023). And after all, learning about the mole is so difficult for high school students and we should all adopt to […]

12:20 PM | The 2014 Nobel Prize in Chemistry and tool-driven scientific revolutions
Image: Nobelprize.orgLast year I wrote a post detailing the views of historian Peter Galison and physicist Freeman Dyson of science as being as much of a tool-driven revolution as an idea-driven one. Now here's a great instance of that tool-driven paradigm change: this year's Nobel prize for chemistry which was awarded to Eric Betzig, Stefan Hell and W. E. Moerner for single molecular techniques, especially single molecule fluorescence microscopy and spectroscopy. The prize has been awarded for […]
