Using stories to make science accessible to all seems to be a theme at the sessions I have attended at the ACS meeting.

At this afternoon’s session of the ACS for the Arthur C Cope and Arthur C Cope Scholars Awards a (rather large) room full of delegates met to listen to outstanding scientists like David MacMillan who received an award for his work towards the synthesis of complex chiral molecules. MacMillan compared the efficiency of the techniques he uses and their potential to the legend of the grains of rice on a chess board.

Another young investigators such as Janis Louie gave a comprehensive and instructive talk on the uses of Nickel catalysts in cycloadditions.

The session was wrapped up by the colour-blind, award winner, Jean Fréchet, who talked on macromolecules at the interface between organic and materials chemistry. The talk was split in to two parts to showcase the work of his research group. The first part looked at using organic electronics to make monolayers that can self-assemble and act as electrical transistors.

The second part of the talk was based more on what I would consider to be ‘characteristically’ the work of Fréchet – developing dendritic macromolecules for use as cancer chemotherapeutics.

Here at the Fall ACS meeting in Boston, we have been treated to a twist in the tale of a famous fable.

A fascinating question that a lot of scientists try and answer is ‘how did life start of earth?’ Professor Doug Philp from the University of St Andrews is trying to answer this question using simple chemistry. But the situation isn’t as simple at is seems. Although simple chemical systems in which compounds make copies of themselves are well understood, as soon as there are a number of compounds that could be formed in the system things get tricky.

Speaking as part of a symposium in honour of Sir Professor J Fraser Stoddart, named ‘Chemistry of the Mechanical Bond and Beyond’, Philip used the analogy of Aesop’s ‘the hare and the tortoise’ fable to bring the complexity of the situation to life. However, far from the ‘slow and steady’ approach winning the race, Philp’s replicating systems mean you can snooze for most of the afternoon under a tree and still win. These systems are sufficiently powerful as to effectively kill off the tortoise in favour of fitter hares.
