1:27 PM | A sad, puzzling #altchemjobs anecdote
From Sam Stein of The Huffington Post, an interesting anecdote in a story about young scientists and their issues with the current federal funding climate:One particularly jarring example of this brain drain, recounted by two independent sources, took place in the summer and fall of 2012. A young researcher in the Midwest with a Ph.D. in chemistry from a prominent state school had been left unemployed after the project on which she had worked didn't get a follow-up grant. Three months of […]

1:19 PM | Patrick Harran pleads not guilty on 4 felony counts, LADA adds one more count to previous 3
From C&EN's Michael Torrice, the latest from the #SheriSangji case:University of California, Los Angeles, chemistry professor Patrick Harran was arraigned today on four felony charges of violating the state labor code. A Los Angeles County judge entered a not guilty plea on Harran’s behalf for all four counts. The charges stem from the death of research assistant Sheharbano (Sheri) Sangji from injuries sustained in a 2008 fire in the professor’s lab. Another judge ruled last month […]

1:15 PM | Numbers of Atoms: Finding the smallest traces with gas chromatography
We conclude (for now) our look at chromatography for separations and quantitative analysis by considering instruments that offer even more sensitivity and selectivity than the high-performance liquid chromatography (HPLC) methods described in the last post. But you said that HPLC can give detection limits in the parts-per-billion range.  That seems … Continue reading →

12:08 PM | Friday Fun: Who Should be Science Laureate?
Perhaps this little tidbit from ScienceInsider got lost in the shuffle yesterday:Looks like Washington wants a Science Laureate, a travelling scientist "national spokesman for science" to rove about the country drumming up support and excitement. From Sen. Hirono's (HI) office:"This new honorary position would be appointed by the President from nominees recommended by the National Academy of Sciences and serve for a term of 1-2 years. Using this national platform, the Science Laureate […]

11:06 AM | New magnetic graphene may revolutionize electronics
Researchers have managed to give graphene magnetic properties. The breakthrough opens the door to the development of graphene-based spintronic devices, that is, devices based on the spin or rotation of the electron, and could transform the electronics industry.

10:46 AM | Unusual behavior of graphene under irradiation: More damage - less noise
The low-frequency 1/f noise is a ubiquitous phenomenon found everywhere from fluctuations of human heart rates to fluctuations of electrical currents in semiconductor devices. An acceptable level of flicker 1/f noise is one of the key metrics that each new material has to pass before it can be used for practical devices. Graphene has shown a great potential for applications in high-frequency communications, analog circuits and sensors. The envisioned applications require a low level of 1/f […]

10:26 AM | An eventful week for Manchester United
Sir Alex Ferguson’s retirement has been on the cards for some time, so when the rumours started flying around on Tuesday night I was not particularly surprised. After all, he has served the club immensely well for over 26 years, and it made a lot of sense for him to retire on a high note, […]

7:15 AM | Charting Europe's nanotechnology roadmap
In a field which requires a high degree of coordinated effort involving many different stakeholder groups, including researchers, policymakers and commercial players across a wide variety of industrial sectors, it has perhaps been inevitable that fragmentation, disconnectedness and duplication have stood in the way. NANOfutures was set up in 2010 to tackle exactly this problem of fragmentation.

1:25 AM | Chemistry, fluid dynamics and an awful radioactive mess
When it comes to handling radioactive waste the Hanford site in western Washington state is the opposite of a role model. Ever since its reactors started producing the plutonium which was used in the Nagasaki bomb, Hanford has been generating waste with little foresight and responsibility. It has the dubious honor of being the most contaminated radioactive site in the country. Scientific American has an article which gives an idea of how truly awful the problem is. It's not just that there's […]

5:23 PM | Pathogenic E. coli thrive both in gut and bladder
Like jet-setting celebrities with homes in more than one location, some pathogenic strains of E. coli make two different places in the human body their homes. In a paper just out in the journal Science Translational Medicine, researchers describe how recurrent urinary tract infections in women may be caused by E. coli strains that can […]

4:02 PM | So depressing
C&EN was advertising this auction for an old Rochester, NY photochemical plant's equipment earlier this week in its banner ads. It's not like they were long for this world, what with digital photography being what it is. But it's still sad to me, I dunno why.

3:59 PM | What does it take for a chemist to become a chemical engineer?
Here's a hypothetical question that I get a lot, that I don't have an answer to:Hey, CJ: I'm a [insert here: junior undergraduate/new B.S. chemist/experienced Ph.D. chemist] and I'd like to get some of that sweet, sweet fracking cash and become a chemical engineer. How can I go back to school for this? Love, a readerI honestly have no idea, even though I know some people who have gone this route. It seems to me that most of it requires some remedial undergraduate level […]

3:27 PM | A very good point by Jyllian Kemsley
William Banholzer and a group of other high-level chemical corporation executives wrote a letter in this week's C&EN, where they really took academic chemical safety to task* ** -- and used an interesting metric to do it:The facts are unequivocal. Occupational Safety & Health Administration statistics demonstrate that researchers are 11 times more likely to get hurt in an academic lab than in an industrial lab. There have been serious accidents in academic labs in recent […]

2:01 PM | The Oil Economy - It Will Be Around Longer Than Anyone Thinks
A few weeks back, the Atlantic ran a story provocatively entitled ""What if We Never Run Out of Oil?". The long and short of the 11,000 word article is that methane hydrates (ice crystals of methane and water that form under high pressure) litter the coastal ocean floors, and if the technology could be developed to recover them, we could see a future of abundant energy. (i.e., retrieve the icy-solid hydrates, bring them to the surface and you have methane gas separating itself from the water […]

Good morning! Between May 7 and May 8, there were 21 new positions posted on the C&EN Jobs site. Of these, 4 (19%) are academically connected and 8 (38%) were from Kelly Scientific Resources.Toronto, Canada: This is a classic example, in my opinion, of the bogosity of some industrial postdoctoral positions. From Encycle Therapeutics:Post-Doctoral Scientist The position is centered in synthetic organic chemistry with an emphasis on peptide chemistry; research will be carried out on […]

11:08 AM | Single-molecule nanopore research made easy
Nanopores are an exciting class of single molecule nanosensors. For several years now, nanopore technology has been developed as a biosensor at the single-molecule resolution to detect an array of biomedical molecules, such as DNA, RNA, protein, biotoxin, and various nanopore projects have been funded to develop the next generation of DNA sequencing technology. The sensing principle is based on the resistive pulse technique - molecules are detected as they pass through a single nanopore since […]
