8:18 AM | Direct and label-free discrimination of cytosine and its modifications utilizing silver ions in nanopores
Cytosine (C) modifications such as 5-methylcytosine (mC) and 5-hydroxymethylcytosine (hmC) are important epigenetic markers associated with gene expression and tumorigenesis. However, bisulfite conversion, the gold standard methodology for mC mapping, can not distinguish mC and hmC bases. Recent studies have demonstrated hmC detection via peptide recognizing, enzymes, fluorescence and hmC-specific antibodies - nevertheless, a method for directly discriminating C, mC and hmC bases without […]

9:45 PM | Synthetic Cannabinoid Illnesses in NH - August 2014
New Hampshire Governor Maggie Hassan has issued a state of emergency after a rash of overdoses on synthetic cannabinoids. On Monday night in Manchester, NH, there were 17-25 reported illnesses. There were 9 reported synthetic cannabinoid-related illnesses on Tuesday night. There have been at least 3 illnesses in Concord, NH in the last 24 hours.Some of these incidents were allegedly associated with a bubblegum flavored herbal incense product named "Smacked!". Two other products named in the […]

3:46 PM | Academic family: Sir William Ramsay
Guest post by Jessica Breen ‘The noblest exercise of the mind within doors, and most befitting a person of quality, is study’ – Ramsay A few years ago I had the pleasure of meeting Jack Dunitz at the Swiss Federal Institute of Technology (ETH) in Zurich. Little did I know that he was the academic [...]

3:24 PM | Meet our guest bloggers – Jessica Breen
I am a postdoctoral fellow at the Institute of Process Research and Development (iPRD) at the University of Leeds. My research is on the synthesis of chiral amines relevant to the pharmaceutical industry but I have a general interest in organic chemistry, catalysis and sustainable methodologies. When I am not in the lab, I blog [...]

3:06 PM | Quote of the day: penicillin frustration
For some reason, I was reading about the scaling-up of penicillin and came across this wonderful quote, via an ACS writeup:Pfizer's John L. Smith captured the complexity and uncertainty facing these companies during the scale-up process: "The mold is as temperamental as an opera singer, the yields are low, the isolation is difficult, the extraction is murder, the purification invites disaster, and the assay is unsatisfactory."You know, that gives me a bit of perspective.

2:00 PM | Grant submitted, now what?
  You’ve spent years in training. You’ve spent months developing a project, collecting preliminary data, publishing manuscripts, and training students. You’ve attended all of the grant-writing workshops. Hopefully you’ve followed our advice on a stress-free grant writing experience, and you’ve now spent weeks writing your grant, editing your grant, generating tables, graphs, and other figures […]

12:40 PM | Oh Brave New World!
I start a new aspect of my polymer chemistry career today - my first attempt at synthesizing an inorganic polymer. Up till now, acrylates, urethanes, ureas, polyesters (with and without styrene) and countless organic biobased substrates have been my playground. Today however, I need to strike out in a new direction, one where silicon and oxygen will now be the atoms of the polymers backbone. Carbon will still be around, but only as a moiety.It's pretty exciting, not just because of the new […]

12:25 PM | How Not to Stink!
Last week we looked at why we sweat and why it smells, but it doesn’t have to be like that! We saw that sweat can be affected by many factors – including  how many X chromosomes you have (by the way, if genetics is not your strong point, females are XX while males are XY). [...]

8:00 AM | Upconverting synthetic leaf takes it cues from nature
A large part of low-energy photons, such as in the deep-red and infrared, are lost during conventional photovoltaic or photochemical processes. However, about half of all the solar energy reaching the Earth's surface can be found in these wavelengths. Harvesting this light more efficiently is possible thanks to a process called photon energy upconversion. Researchers now have successfully synthesized a bioinspired upconverting solid-state-like film using nanocellulose.
