4:06 PM | Uncovering the forbidden side of molecules
Researchers have succeeded in observing the 'forbidden' infrared spectrum of a charged molecule for the first time. These extremely weak spectra offer perspectives for extremely precise measurements of molecular properties and may also contribute to the development of molecular clocks and quantum technology.

6:01 PM | Botox utilized as a medical prevention of abnormal joint adhesion.
Botox is famous for being used for cosmetic reasons and it is largely used an anti-ageing treatment to try and reverse fine lines and wrinkles on the face. It’s also known to get rid of migraines and headaches caused by possible uncontrollable muscle spasm; Botox inhibits muscle spasms and therefore causes muscle paralysis thus relieving the headache/migraine. Although Botox has a reputation for

4:47 PM | ScienceCareers: Ph.Ds, don't apply for BS/MS positions
This piece in ScienceCareers is rather hard to read. It's about Ph.D. scientists who apply for B.S/M.S.-level positions, written by a scientific recruiter:  The discovery that you’re overqualified for many advertised jobs often comes as a rude shock. You’ve seen the ads, as Jonathan did, seeking skills in your area of expertise—but the employer hasn’t specified a Ph.D. Instead, the employer is seeking someone with a Bachelor of Science or a Master of Science […]

4:20 PM | NSF finds chemist "involuntary out-of-field" rate is 2.0% for 2013
Via H1-b skeptic Norm Matloff's blog*, I see that NSF has reported the rate of all chemistry Ph.D.s that are involuntarily working outside of their field at 2.0% for 2013. This is defined as "Involuntarily-out-of-field rate is the percentage of employed individuals who reported, for their principal job, working in an area not related to the first doctoral degree at least partially because a job in their doctoral degree field was not available."As far as I'm concerned, this is incredibly low, to […]

3:31 PM | THE SCOTTISH REFERENDUM 2014: A Nation Decides
Originally posted on angiesallsorts:The referendum ballot boxes have been counted from an unprecedented electorate turnout of 84.51% and Scotland has decided to remain within the United Kingdom. The No campaign (against independence) gained 55.3% some 2,001,926 votes cast, whilst the Yes campaign (for independence) gathered 1,617,989 votes or 44.7% in the polls. From the…

2:55 PM | Quick-change materials break the silicon speed limit for computers
Faster, smaller, greener computers, capable of processing information up to 1,000 times faster than currently available models, could be made possible by replacing silicon with materials that can switch back and forth between different electrical states.

1:51 PM | Bayer's MaterialScience Spinoff
Plastics Today is reporting that Bayer is spinning off their materials science business, which include polyurethanes and their monomers, and also polycarbonates. There had been rumors for awhile that Bayer was going along this path, but I always figured someone would buy the business rather than have it spun-off.I've never been party to a spin-off, rather I've been on the "spinning" side. While there are certain advantages (the company has more independence and can seek capital from a multitude […]

9:48 AM | The Scottish Independence Referendum Result
Of course I’m pleased and relieved at the referendum result. A majority of 55% for the NO vote is  significant, especially after the (apparent) closeness of the predicted result the weekend before last. In the last few days I have been increasingly concerned about not just the effect of a Yes vote on Scotland, but […]

7:26 AM | Experimenting with smartgel gelation
Scientists are experimenting with a new method of gelation. They can add nanoparticles or biomolecules with useful pH, chemical, and temperature sensing properties into a liquid, but incorporating those liquids into existing technology proves difficult.

12:10 AM | Publication of the week, number 43, 19th September 2014
This week’s contribution comes from “Down Under” and discusses the isolation of some new cyclic peptides. It was reported by Capon etal from the University of Queensland. Amongst the compounds they obtained from a soil sample were Wollamide A and B. In blue are two D amino acids an ornothine and a leucine. They were isolated from […]

7:24 PM | Raspberries, Weight Loss, & The Galaxy – The Chemistry of Raspberries
Raspberries, like all fruits, contain a complex mix of organic compounds. Unlike many fruits, however, raspberries have the less common distinction of lending their name to the compound that is a major contributor to their aroma – and one of the compounds that contributes to their flavour has also been detected in the centre of our […]

6:51 PM | Solar cell researchers break the 'electrode barrier'
For decades, polymer scientists and synthetic chemists working to improve the power conversion efficiency of organic solar cells were hampered by the inherent drawbacks of commonly used metal electrodes, including their instability and susceptibility to oxidation. Now for the first time, researchers have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the 'electrode barrier'.

5:37 PM | New insights into the world of quantum materials
Physicists experimentally observed how the anisotropic properties of particles deform the Fermi surface in a quantum gas. The work published in Science provides the basis for future studies on how the geometry of particle interactions may influence the properties of a quantum system.

5:36 PM | A mouse model for childhood obesity
  Over the past 30 years, childhood obesity has more than doubled and teenage obesity has quadrupled. Researchers want to identify and understand the molecular triggers that set off children down the obesity path.  “There is considerable evidence that the prenatal environment can predispose the offspring to obesity. This is most clearly seen in children […]

4:20 PM | Researchers design an 'artificial nose' to detect DNA differentiation with single nucleotide resolution
This is a method of identification of nucleic acids, with single nucleotide resolution, based on the generation pattern (bar code) inspired by our olfactory system. The differences in trans-membrane transport can be used to generate fluorescence patterns. That allows the differentiation of molecules as DNA or RNA by means of pattern generation and/or recognition protocols.

10:37 AM | The Chemistry of Champagne: The Secret of the Bubbles
For something usually associated with the freedom of celebrations, producing Champagne is actually a highly regulated endeavor. It’s not enough that it needs to come from Champagne in France, but it also needs to follow a strict set of rules and regulations from the planting of the vines to labelling and packaging the final product, not to [...]
