SB students resources

Introduction to our students resources in Synthetic Biology

(Marko Dolinar)

Synthetic biology made a vast progress in good 10 years since it established itself as an interdisciplinary field of research on the interface of molecular biology and engineering. University of Ljubljana Faculty of Chemistry and Chemical Technology has introduced a Synthetic Biology course as a part od Biochemistry MSc programme only in 2013/14. This is relatively late, considering a great success of Slovenian students at iGEM competitions since their first attendance in 2006. On the other hand, the field is still in its first stages if development and a complete textbook for a MSc level course is still missing. This is the reason why our students collaborated on the preparation of a Synthetic Biology textbook with the working title Synthetic Biology - A Students Textbook. It exists as a draft that is not publicly available and is actually part 1 of a (to be) 2-volumes title. Part I is subtitled Engineering Biology, while Part II (that currently doesn't exisist yet) will be subtitled Synthetic Biology Applications.

As in all highly competitive fields of science and technology, students should be following recent progress by reading articles in high quality journals. However, this is often a very difficult task, especially at the BSc level. Specificities of the scientific and technical language, push of publishers towards very short methodological chapters and limited knowledge studens might have about advanced techniques make understanding papers a very challenging task. Therefore, I decided to face MSc students with the challenge to explain selected SB articles in a manner that would make the content of these articles understandable to BSc level students and non-experts.

In 2014/15, seminars in Synthetic Biology include explanations and presentations of some of the top-cited articles from the field of Synthetic Biology. I compiled a list of 95 articles published between 2000 and 2014 having the highest number of citations according to the Web of Science database. The list ended with the paper just exceeding the 100 citations limit. Not included in the list were reviews. With 20 students enrolled in the course, the list has been further reduced to top 40 papers in the field. Students have been asked to check for content (they further eliminated 3 papers which proved to be reviews) and availabitly (they all seemed to be available as full texts with our university subscriptions). My suggestion was to avoid selecting for presentation papers with very similar content. Especially in the field of genome editing there has been a very rapid progress in the past few years resulting in a number of highly-cited articles which could appear very similar in content for a non-specialist. From the shortlist of 37 articles, students selected a topic they believed would be most interesting or easiest to explain. Presentations will be both written (in English, which is not the mother tongue of my students) and oral (in Slovenian, to establish and maintain Slovenian terminology in the field).
