Brewing coffee might be the most practiced chemical extraction in the world. But within this process there are many variables, all of which dictate the flavour of the resulting coffee. (more…)

In the wake of AstraZeneca’s (AZ) stout rebuttal of Pfizer’s overtures to a takeover bid, media all over the place are reporting the ‘disappointing’ news that AZ’s share price has ‘tumbled’. In my opinion this is typical of the short-memory effect that looking at share prices seems to somehow bestow on even some quite sensible people.

Look at the facts and circumstances – AZ has just been subject of speculation over a possible takeover. This inevitably leads to an increase in the share price as speculators look to take advantage of the premium price that any bid is bound to offer, or the rising price in the build-up (partly caused by demand arising from their own speculation).

Once the possibility of that short-term gain is removed – in this case by AZ shutting the door in Pfizer’s face – the price will inevitably go down, as those short-term investors seek to cash in their holdings and go off elsewhere in search of another stock that’s on the rise.

But here’s the important bit. AZ’s share price is still significantly higher than it was in the middle of April, before all this talk started. The only people who have actually lost money are the ones who bought their shares after 25 April, and sold them yesterday or today.

It is slightly more revealing to look at Pfizer’s share price over the last couple of months, which overall is significantly down. This wasn’t helped by some decidedly mediocre sales figures in the company’s quarterly announcement at the beginning of May. And the further Pfizer’s price falls, the less valuable that combined cash-and-stock offer becomes.

As well as sponsoring the prize for the best poster at ISACS13, this July, Chemistry World is also sponsoring prizes at two more events in the series, ISACS14 and ISACS15!

Challenges in Organic Chemistry, ISACS14, to be held in Shanghai, China, this August, follows the success of ISACS1, in 2010, and ISACS7, in 2012, and will feature experts in the field of organic chemistry and synthesis.

Two weeks after ISACS14, Challenges in Nanoscience, ISACS15, is taking place in San Diego in the US. It will bring together scientists from across the world to discuss the latest advances in nanoscience and will encompass a broad range of disciplines, including chemistry, biology, physics and engineering.

Talks from leading experts in both fields are complimented by extensive poster sessions that will provide many networking opportunities.  To take advantage of this opportunity to showcase your latest research alongside leading scientists submit your poster abstract by 2 June for ISACS 14 and by 9 June for ISACS15. The winning poster will be chosen by the ISACS scientific committee and each winner will be awarded a prize of £250 and a Chemistry World mug .

Last week I attended the British Science Association’s Science Communication Conference in Guildford, Surrey. The conference explored a number of avenues, from the role of design and data visualisation through to the relevance of the whole academic field of science communication. As you might expect for a conference populated almost entirely by communicators, there was as much discussion on twitter (under the umbrella of #SciComm14) as there was in person.

This tweet gained instant traction. It demonstrates neatly that in order to understand scientific reporting, one must first learn to speak the language of science. The image comes from a 2011 feature in Physics Today on communicating the science of climate change.

There are arguments for and against using ‘accessible’ alternatives, depending in part on the desired outcome of your communication. In a more formal educational setting, for example, it may be best to use these ambiguous words along with their scientific definition, so that they can be used in their full scientific context in future. Conversely, some words are tainted by association – chemical and nuclear both have negative connotations, so a push towards their scientific use may help to break that stigma. Whatever good intentions one has, insisting that ‘the public’ use ambiguous language in a certain way seems patronising and ultimately doomed to fail (after all, we still hear that evolution is ‘only a theory’). Protecting scientific language in this way may, therefore, reinforce the dividing line between ‘scientists’ and ‘the public’.

Thinking that now would be a good time to extend this list, I asked what other words people would like to see added. (more…)

It’s spring. It’s the end of the financial year for many companies. And it’s the time of year when a lot of them hold annual shareholders’ meetings, so there’s a certain temptation to make announcements that will excite shareholders (or maybe that’s just me being cynical). Some or all of those things may be contributing to the media and rumour mills working overtime about mergers and acquisitions in the pharmaceutical and chemical sectors.

Its a deal

It seems to be open season for pharma deals, but how many of them will actually go through?

For the last few years, things have been rather quiet in terms of pharma megamergers – in which already large companies crash together in the hope of finding ‘efficiency savings’ and ‘synergies’. Most of the more recent deals have been big companies snapping up smaller startups to acquire specific products or technologies that fit with their priorities. A lot of analysts and industry commentators have been making noises along the lines of ‘pharma has learned its lesson: megamergers cause a lot of disruption for not much overall gain’.

But then, in February, consultancy firm McKinsey put out a report that essentially said, ‘you know what, those mergers did actually do something positive, they “resulted in positive returns for shareholders”’. Whether or not this is a good thing for the overall health of the firms, and of their R&D pipelines is another discussion entirely.

We had an unusual request to the Chemistry World office this week. A producer from Simon Mayo’s BBC Radio 2 drivetime programme wanted to know if it’s possible to make a diamond from human hair.

The query was prompted by the news that Brazilian football legend Pelé had announced a range of diamonds, each made from a strand of his hair, to commemorate each of the 1283 goals he scored in his professional football career.

It seemed a fairly straightforward request – there’s plenty of carbon in hair and it’s certainly possible to make diamond industrially from a carbon source – so I volunteered to take the call. (more…)

What makes a news story ‘news’? How do journalists construct an article? What sort of cake do they have in the Royal Society of Chemistry restaurant? If any of these questions have occurred to you, then you might be the person we’re looking for.

If you follow us on Twitter you’ll know that I spent 16-20 March in Dallas, Texas for the ACS spring conference, hearing about peptides that attack TB, dissolvable electronics and new drug testing methods.

Chocolate absorbing volatiles from wine

I was also happy to find that – perhaps fitting for a state known for generous helpings – there was plenty of food and booze research on the scientific agenda.

First up, chocolate. We all love it, and apparently so do the bacteria that live in our guts. Dark chocolate has been linked to various heart and metabolic heath benefits in past studies. Now, a group led by John Finley at Louisiana State University, US, may have come closer to figuring out the reasons behind some these effects. Dark chocolate with a high cocoa content contains polyphenol antioxidants (such as catechins which are also found in tea), but these are poorly digested and absorbed in the gut, so this is unlikely to be the full story.

On the 24th of June this year, Chemistry World will be presenting a prize for an outstanding poster during the 3rd Royal Society of Chemistry Younger Members Symposium (YMS2014) at the University of Birmingham in the UK.

YMS2014 is a one-day event organised by the RSC Younger Members Network. This interdisciplinary symposium aims to provide young chemists with the opportunity to present at a major national conference, as well as the chance to network with their peers and to find out about the latest advances across the chemical sciences. Professor Lesley Yellowlees (President of the Royal Society of Chemistry) and Professor Alice Roberts (Head of Public Engagement at the University of Birmingham) will be giving keynote lectures at the conference.

Early-career chemists from all disciplines are invited to register and submit abstracts for oral and poster presentations. Posters should have a clear scientific rationale and present the author’s latest work. They will be judged on the quality and originality of the work as well the presentation skills of the author, with special emphasis on their ability to communicate their work to non-experts from other disciplines.

There will be four parallel sessions: Education & Outreach, Organic & Biochemistry, Physical & Analytical and Inorganic & Materials. Chemistry World is proud to be sponsoring the poster prize for the Inorganic & Materials category. I’ll be judging the prize alongside a select committee and the winner will receive £150, with £100 and £50 going to the runners up. Winners in this category will also receive a Chemistry World mug and a copy of The case of the poisonous socks by William H Brock.

To register for the conference, visit this page: rsc.li/NzUB06 

We look forward to reviewing your posters.

Jennifer Newton
