5:53 PM | This Week In Chemistry: Methane on Mars, & a Nicotine Patch Alternative
Here’s the weekly summary of chemistry research and news, this week featuring stories on the discovery of methane ‘burps’ on Mars, a reaction to join alkenes that can be carried out in whiskey, and a potential improvement on nicotine patches for quitting smoking. As always, links to further articles and original research papers are provided below […]

These are 5 structures of protein-ligand interfaces described by van-Molle and colleagues in 2012. I lined them all up with one another using the BLOSUM62 matrix in UCSF Chimera’s MatchMaker alignment module, which simply finds the structures that can be superimposed with as many matching residues as possible, and the minimum distance deviation between them (Meng et al. 2006). The red structure (PDB: 4ajy) looks a bit different and messes up the continuity of the animation as it’s […]

2:02 PM | Data sharing
When you want to share data with others, the first thing you need to decide is under what terms. Do you want others be able just look at the data, change the format (Excel to CSV, for example)? Do you want this person to be allowed to share the data within his research group, or perhaps collaborators?Very often this is arranged informally, in good faith, or by some consortium, confidentiality, or non-disclosure agreements. However, these approaches do not scale […]

10:00 AM | Sunrise still later after Winter Solstice
Several people asked me about the odd phenomenon that in these here parts sunrise gets later each day until early January even though the days themselves get longer after the winter solstice. From EarthSky: The winter solstice always brings the shortest day to the Northern Hemisphere and the longest day to the Southern Hemisphere. But, […]Sunrise still later after Winter Solstice is a post from the science blog of science journalist, photographer and musician David Bradley Subscribe […]

9:13 PM | Beta-amyloid: the emperor really does have no clothes
Beta-amyloid: the emperor really does have no clothes: Yesterday, Roche announced its decision to discontinue its Phase 3 study of gantenerumab, its experimental anti-amyloid antibody, in early Alzheimer’s Disease. The study failed a futility analysis – the clearest possible evidence of a lack of signal. This marks the latest nadir for the amyloid hypothesis – the dominant collective understanding  of the molecular pathogenesis of Alzheimer’s Disease for more […]

4:14 PM | Great News for Wikipedia Lovers
We were always warned at university about the reliability of Wikipedia and that we shouldn't use it for guidance when working on projects and/or coursework and we're recommended to use Google Scholar and Science Direct for scientific research. Because Wikipedia is an open online encyclopedia in which everyone and anyone can edit and add to the pages, its reliability isn't 100%.However the good news is, is that the Royal Society of Chemistry (RSC) have given access to the […]

2:11 PM | Pearly Whites = Perfect Health [Info-graphic]
Our teeth make up one of our most important features: our smile. So it's obvious we'd want to find the best possible ways to look after them and make sure they're in the best condition they could be in and also avoid the dentist at all costs! In the UK at least 15% of adults have severe periodontitis caused by bacteria residing in “bio-films” or dental plaque causing the inflammation and swelling of the oral tissue surrounding our teeth.Even if there are updated ways to treat […]

10:00 AM | La línea entre lo que consideramos vivo y lo que no [Charla TED de Martin Hanczyc]
Está claro que si nos enseñan un cristal y un lindo gatito y nos preguntan cuál de los dos podemos considerarlo como un organismo vivo todos responderíamos que el gato. ¿Y los virus? Pues seguro que habría algún tipo de mini-polémica y no todo estaría tan claro. ¿Dónde ponemos el límite? Obviamente en la definición biológica de vida y en este caso los virus quedarían fuera. Y […]

3:04 AM | Notice of Intent – 3 More Synthetic Cannabinoids into Schedule I
Today, December 19, 2014, the United States Drug Enforcement Administration (DEA) filed a notice of intent for placement of three new synthetic cannabinoids into Schedule I of the Controlled Substance Act (CSA). These three substances are:AB-CHMINACA, AB-PINACA, and THJ-2201All three of the substances have been discussed at one time or another here on TDMTP and are suspected to be CB1/CB2 receptor agonists, but true pharmacological and toxicological evidence does not exist. AB-PINACA is […]

7:20 PM | The Aroma of Christmas Trees
  The aroma of pine trees is one that’s evocative of Christmas; one of the responsible molecules, alpha-pinene, has already been featured on the Chemistry Advent Calendar, but here we take a more detailed look at the chemical constituents of the aroma. One of the most important contributors to the Christmas tree aroma is pinene. […]

Here’s something we’re sure many of our readers will find interesting. This week The New Yorker delves into the strange properties of graphene, the first two-dimensional material ever discovered. Despite its unparalleled strength and conductive properties, scientists are still struggling to find a world-changing, everyday use for it. But be quick; the story will go behind their paywall next week. Image: A layer of graphene only a single atom thick is stronger than an equivalent […]

5:29 PM | Researchers open a possible avenue to better electrolyte for lithium ion batteries
The lithium-ion batteries that mobilize our electronic devices need to be improved if they are to power electric vehicles or store electrical energy for the grid. Researchers looking for a better understanding of liquid electrolyte may have found a pathway forward. They found surprising results in the first X-ray absorption spectroscopy study of a model lithium electrolyte.

4:16 PM | Countdown to the 2014 Chemistry World science communication competition
Tessa Fiorini won last year’s Chemistry World science communication competition. Here, she writes about the inspiration for her article by a holiday in Prague, about her time at the prize-giving event and her winner’s trip. When I heard about Chemistry World’s science communication competition last year, I had just come back from a holiday in Prague. The [...]

3:40 PM | A neat ozone+UV paper pointed out by See Arr Oh
Check out this really interesting Science paper highlighted by See Arr Oh, one where the authors transform cyclohexane to adipic acid (among other transformations) using ozone and 300 nm UV light. Obviously, this is a pretty neat method and one that should be highlighted to the broader scientific community.I think it's obvious to the authors that a batch reactor approach is/would be sufficient for the laboratory, but not for industrial applications to large-scale polymer needs. From the […]

3:18 PM | New cell culture technique paves the way for tailor-made cancer treatments
In a development that could lead to a deeper understanding of cancer and better early-stage treatment of the disease, researchers have devised a reliable way to grow a certain type of cancer cells from patients outside the body for study. The new technique is more than three times as effective as previous methods.

11:36 AM | Shapeshifting metal nanoparticles eating tracks in graphene
A widely discussed method for the patterning of graphene is the channelling of graphene by metal nanoparticles in oxidizing or reducing environments. Researchers have now performed in-situ transmission electron microscopy experiments of silver nanoparticles channeling on graphene and discover that the interactions in the one-dimensional particle-graphene contact line are sufficiently strong so as to dictate the three-dimensional shape of the nanoparticles.
