5 minutes with Ben Davis, Chemical Science Associate Editor

Get to know our Editor-in-Chief and all of our Associate Editors on this blog over the coming months!
This month, we break the ice with Chem Sci Associate Editor Ben Davis.

Ben Davis is Professor of Chemistry at the University of Oxford, where he is a Fellow and Tutor in Organic Chemistry at Pembroke CollegeHis group’s research explores the exciting and rapidly expanding interface between chemistry and biology, with an emphasis on carbohydrates and proteins.

An Editorial Advisory Board member of Chemical Science since its launch in 2010, Davis now serves as one of the journal’s Associate Editors, handling submissions in chemical biology.

What excites you most about chemical biology?

I think it’s probably the unique position chemistry is now in, to be able to address the really fundamental questions about how biology works at a molecular level.  Not just static stuff or indirect, but a combination of strategies that will unpick what you might call mechanistic biology.  We’re at a real turning point in science, where biology now needs to be that detailed, and chemistry has now developed the tools to deliver that detail – the two fields are genuinely starting to shake hands properly.

If you could go back in time, which scientist would you most like to meet or work with?

They’re all so very different.  Probably Boyle.  Because he was mad, brilliantly mad, completely unfettered by convention.  Very creative.

What’s the best advice a mentor or supervisor has ever given you?

Probably the best advice I’ve ever had was from Brian Clough, who told me I should “smile more.”  But then I don’t think you can really count him as a mentor.  Probably the best mentorship advice I’ve ever had was that you need to pick interesting, big problems.  Life is short, so pick big stuff.  Pick things that matter and that excite you, and do it through passion, and don’t waste time worrying about what other people will do, and what other people might take from you.  If you don’t have enough ideas to keep moving forwards and testing fresh things, no matter what other people are doing, then you are probably in the wrong job.  It’s not about the individuals, it’s about the science.

What do you enjoy doing when you’re not in the lab, teaching, writing, or handling Chem Sci papers?

I row, basically.  Indoor/outdoor, whenever I can, however I can.  Pembroke College Boat Club (Head of the River) is a near utopian state.

If you were to be shipwrecked on a deserted island, which item currently in your pocket would be most useful to you?

I haven’t got anything in my pockets.  I have this habit of emptying my pockets when I go into a room – frees the soul.  I’m not really that dependent on the stuff in my pockets, to be honest (and I hate pod-zombies).  So, no, nothing really.

What makes a Chem Sci Edge article HOT?

Innovation.  Creativity.  Difference.

Describe Chemical Science in three words.

Challenging current chemistry.  I’d say, Chemical Science is making people think about the way chemistry is researched and published, putting out stuff that’s different and trying to break down the traditional routes of dissemination whilst maintaining the ethics of proper, rigorous peer review by experts.  Its freshness is powerful, and this is generating a powerful and unique group of authors, reviewers and readers, I think.

Your personal message to Chem Sci authors and readers?

What I’d love to be able to say to authors is that they should think really carefully about how they write papers and where they put those papers.  In an era when the value of publication is in danger of being eroded, it’s probably more important, rather than less important, to write quality papers and put them into a journal that’s going to mean something long-term, has a good audience, and has – impact is the wrong word – but has something that connects with people that matter (now and in the future).

There’s this increasing trend for not peer-reviewing, and not doing things with rigour, things just being posted up and being reviewed in real-time, and all of this stuff which is undermining the quality of science we publish.  We seem to have forgotten that over 350 years ago, we developed a sensible and intelligent mechanism of trying to ensure that quality wins out.  Expert peer review, in my experience, always improves the science if all involved are sufficiently open-minded and hungry to do better.  The idea of creating mounds of poorly evaluated data and analyses without any true advice or moderation is madness (and something we turned our back on as a community in the 17th century).  True scholars want to get better and do better by getting advice, not getting their stuff out at any cost (the latter are just blaggers or advertisers).

This quality is what will really matter in 50 years’ time, when we’re all probably dead and buried (at least some of us) – then the legacy will be the paper, and only the paper, and the science that’s in it.

And so it needs to be somewhere that’s going to have longevity and impact.  It’s even more important to put it somewhere that is rigorous in its process, that makes you do better, that tests you and pushes you to create better work.  Then you create something that you’re proud of, and then the paper will speak for itself; whereas if you go to journals that will just let you get stuff in (slop buckets), then it’s almost pointless.

Which means– publish less, but publish better.

Ben Davis and our dynamic international team of Associate Editors make direct decisions on the content of Chemical Science and actively drive its scientific development – submit your best and most innovative work to any of their Editorial Offices.

Seeding removes barrier to curious cocrystal

Michael Parkin writes on a HOT Chemical Science article in Chemistry World

After seven years of work, a team of chemists based in four labs across the globe has successfully prepared a cocrystal previously believed to be unobtainable.

Cocrystals are crystalline materials composed of two or more molecules held together within the same crystal lattice. Cocrystallisation is significant in the pharmaceutical industry, where drug molecules are screened for cocrystal formation in order to improve their solubility, stability and bioavailability. This has the added advantage of increasing the number of crystal forms that can be considered for drug formulation while simultaneously maximising patent protection.

Despite a computational study suggesting a stable cocrystal should form between caffeine and benzoic acid, all previous attempts over the last 60 years have failed. ‘When a cocrystal doesn’t form, we like to understand why that is – patients could miss out on better medical treatment if we miss out on crystal forms,’ says Dejan-Krešimir Bučar at the University of Cambridge in the UK, who led the study. ‘We hypothesised that a kinetic barrier hindered cocrystal formation, so our idea was to add a molecular species similar to that found in the nucleus of the caffeine·benzoic acid cocrystal as a seed to facilitate crystallisation.

Nowhere for hydrazine to hide

Megan Tyler writes on a HOT Chemical Science article in Chemistry World

Scientists from the US and South Korea have developed a probe that can detect the highly toxic chemical hydrazine in a variety of different environments, including living cells.

Hydrazine plays an important role in a number of industrial processes. It’s used in pesticides, in nuclear and conventional electric power plants to reduce corrosion, and as a gas-forming agent in air bags. It’s even found in rocket fuel.

Although contact with small amounts of hydrazine is unlikely to cause harm, long term exposure can damage the liver, kidneys and central nervous system. Hydrazine has also been classified by the US Environmental Protection Agency (EPA) as a probable carcinogen.

Accidental leakage of hydrazine into the environment is rare and as hydrazine breaks down rapidly in oxygen, finding high levels of hydrazine in the environment is unlikely. However, hydrazine exposure in the workplace can be a real danger for individuals who come into contact with it. This makes the development of hydrazine sensors an important area of research.

The probe reacts with hydrazine to make a five-membered ring, resulting in a fluorescent response and a visible colour change

Destroying stable foam on demand

William Bergius writes on a HOT Chemical Science article in Chemistry World

The first example of stable and environmentally friendly foam that can be broken down by any one of three external stimuli has been developed by an international team of scientists.

From left to right: foam before and after an increase in temperature, UV irradiation and exposure to a magnetic field

Foams are commonly applied in the clean-up of chemical spills, where they are sprayed over large areas to prevent evaporation of volatile and harmful organic materials. While this demands stability, the foam then needs to be destabilised for transport due to its voluminous nature, often accomplished by the addition of an anti-foaming agent. The resulting liquid mixture can then be removed and the components recovered. Recent studies have tried to create stable foams which can be destabilised by external stimuli to remove the need for the addition of extra chemicals.

Orlin Velev and Stephanie Lam of North Carolina State University have collaborated with Anne-Laure Fameau from the French National Institute for Agricultural Research, to pool their multidisciplinary backgrounds in foams and emulsions, and colloids.

I challenge thee to a dual labelling

Our guest web writer Sarah Brown blogs about a HOT chemical biology paper on Chemical Science

Lift your right foot off the floor and make clockwise circles with it. Managing comfortably? Now draw a ‘6’ in the air with your right hand – what’s happened to your foot? It’s all gone a bit wrong, hasn’t it? See, it isn’t that easy to do two different things at once. Another example of this is the dual labelling of proteins; however, Stephen Caddick and colleagues appear to have got on top of this, as reported in their recent paper in Chemical Science.

The dual labelling of proteins has the potential to enable studies of protein structures and the construction of theranostics, for example; however, proteins can be complex and modifications are often restricted to the N- and C-termini, limiting their usefulness. Modification of non-terminal positions is tricky and can be slow, expensive and unrewarding. Caddick and colleagues demonstrate a novel approach to site-selective labelling of proteins, which yields a dual-labelled product by the introduction of two cysteine mutants into the sequence, which are converted by a single chemical reagent into two distinct products for modification. One residue, with an accessible alpha-proton, readily forms dehydroalanine, and the other residue persists, by shielding, as a sulfonium that undergoes chemoselective ring opening by reaction with an azide group. Both groups can then be further labelled orthogonally by the desired molecules.

GA?id=C3SC51333E

The group demonstrated their technique by modifying GFP (green fluorescent protein). After incorporation of the cysteine mutants and treatment with a chemical reagent (2, 5-dibromohexanediamide), further treatment with sodium azide generated dual modified GFP. Further reaction with an alkyne modified dye and mercaptoethanol yielded a rhodamine dye and thiol-labelled protein.

The researchers have demonstrated a site- and chemoselective method, which they say offers a facile and generally accessible technique for dual labelling. And now they’ve got to grips with that, I pose the ultimate test: to come up with a facile method for standing on one leg and drawing a ‘6’ – trying to do that and type this blog has also been pretty challenging.

Once you’ve tried out some one-legged multi-tasking, sit back down and read this Open Access Edge Article to see what Sarah’s talking about:

Sarah Brown is a guest web-writer for Chemical Science.  Sarah hung up her lab coat after finishing her PhD and post-doctorate in nanotechnology for diagnostics and therapeutics and now works in scientific publishing. When not trying to explain science through ridiculous analogies, you can often find her crocheting, baking or climbing, but not all at once. All views are her own.

Inaugural Chemical Science Lectureship announced

We are delighted to announce the winner of the inaugural Chemical Science Lectureship – Professor Kevan Shokat.

The 2013 Chemical Science Lectureship was awarded in the area of chemical biology and the award lecture was given at Challenges in Chemical Biology (ISACS11) in Boston, USA, in July. Professor Shokat was presented with his award by Chemical Science Associate Editor, Professor Tom Muir.

Shokat

Tom Muir presenting Kevan Shokat with his Chemical Science Lectureship at ISACS11

Professor Shokat obtained his Ph.D. at UC Berkeley and following appointments at Stanford University and Princeton University, in 1999 he moved to UC San Francisco to his current appointment as Associate Professor of Cellular and Molecular Pharmacology.

The Shokat Lab’s research is focused on using the tools of synthetic organic chemistry, structural biology, genetics, and mathematical modelling to gain insight into how signalling networks transmit information in normal and disease settings. Their guiding principle is to use chemistry to answer questions that cannot be addressed by the use of biochemistry or genetics— they seek to provide tools, which fill in the gaps left behind by more traditional approaches.

Award Details
The lectureship, which will be awarded annually, will recognize sustained excellence in research by a mid-career scientist within the chemical sciences. The recipient of the Lectureship is selected and endorsed by the Chemical Science Editorial Board.

The recipient will be invited to present a plenary lecture at a relevant International Symposia on Advancing the Chemical Sciences (ISACS); they will also receive a certificate, $2000 and will be invited to contribute to Chemical Science.

The 2014 Chemical Science Lectureship winner will give a plenary lecture at one of the 2014 ISACS meetings:

  • ISACS 13: Challenges in Inorganic Chemistry and Materials Chemistry – July 2014, Dublin, Ireland
  • ISACS 14: Challenges in Organic Chemistry (Synthesis) – August 2014, Shanghai, China
  • ISACS 15: Challenges in Nanoscience – August 2014, San Diego, USA

More information about these conferences will appear on the ISACS website soon.

Long-life lithium sulfide batteries

Jeanne Therese Andres writes on a HOT Chemical Science article in Chemistry World

Scientists from the US and China have identified a polymer that makes lithium sulfide batteries last longer.

Electric powered car sign

 Amongst batteries in-use today, lithium ion ones produce more energy per unit mass than most others. However, electric vehicles demand even higher energy batteries with longer charge intervals.

Lithium sulfide batteries can hold much more energy than present-day lithium ion batteries but are limited by their short battery life. This is due to an irregular dispersion of lithium in their electrode slurry, as well as soluble polysulfides being lost when they dissolve in the electrolyte.

Initial numerical modelling followed by lab tests lead Yi Cui at Stanford University and his co-workers to discover that polyvinylpyrrolidone (PVP) can be used to hold a battery’s lithium sulfide and polysulfides during cycling. The PVP allows lithium ions…
