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 […]

By: Amanda White, Research Technologist in the Department of Psychiatry Autumn has arrived, bringing with it some of my favorite scents:  bonfire smoke, pumpkin spice (DON’T JUDGE!), and, most of all, crisp autumn air. Stepping outside on an October morning and breathing instantly transports me back in time. I’m at Penn State. It’s a cool,…

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 […]

9:04 AM | Nobel Prize in Chemistry 2014 honors the principle of nanoscopy
For a long time optical microscopy was held back by a presumed limitation: that it would never obtain a better resolution than half the wavelength of light. Helped by fluorescent molecules the Nobel Laureates in Chemistry 2014 ingeniously circumvented this limitation. Their ground-breaking work has brought optical microscopy into the nanodimension.

8:13 AM | Manipulation of Anthrax to Deliver Cancer Drugs to Tumours
Cancer is acknowledged as one of the most dangerous biological diseases and there are many ongoing research studies to try and find suitable drugs to cure the uncontrollable cell replication. Cancer is caused when cells replicate unusually and rapidly to form tumours, this is because the cell does not undergo apoptosis (the normal programmed cell death) and these tumours need to be treated so

8:23 PM | Updated #chemnobel odds for tomorrow
So today's physics Nobel Prize was awarded to three physicists who worked on blue LEDs, devices that make light bulbs glow brighter and last longer than normal ones. It's a well-deserved recognition, really one for a physics-based invention rather than for a fundamental discovery (as an aside, it's worth noting how much the invention owes to the chemistry of gallium nitride semiconductors). The last time an invention was recognized was when the prize was given out for CCDs in 2009.However I […]
