Special Event

The New Bauhaus Museum Weimar – MACH MIT / JOIN IN

On the occasion of the 25th Anniversary of the STS-Meeting, we would like to invite all participants to visit the Bauhaus Museum Weimar on Thursday, November 3, 1 to 4 pm. The museum highlights the early phase of the most influential school of art and design of the 20th century. The New Bauhaus Museum Weimar was opened in April 2019, showcasing the treasures of the world’s oldest Bauhaus collection. The Bauhaus Museum reveals how crucial processes of change at the start of the 20th century with respect to society, new forms of coexistence, new technologies, material studies were initiated by the Bauhaus.

We have arranged guided tours in English and German of 30 min for you and you will have the chance to stroll around by yourself and enjoy our special event. Transfer from the hotel to the museum and back is arranged.

More information on the Bauhaus museum can be found here.

Poster Sessions

All accepted poster contributions will be on display (poster format: DIN A0, upright, 84,1 cm x 118,9 cm) throughout the Meeting in an assigned poster area together with the sponsors’ exhibition. This comfortable area can be used for vivid discussions at the posters during the coffee breaks. Ample time will be reserved for poster viewing and discussion.

“My Poster in a nutshell" presentations

In addition, all accepted posters can be presented to the plenum in one of the Short Talk Sessions as a concise One-Minute-Short talk. Please prepare one PowerPoint Slide containing key aspects of your scientific contribution to attract participants to your poster. After the short talk presentation it will be possible to meet at the posters for further scientific disussions.

Prizes and Travel Grants

Application Deadline

The deadline for all applications (travel grants, GBM-Innovation-Award, STS Science Award) is 16 September 2022!

STS Science Award 2022

This prize is meant to honor outstanding research by a post doc or a junior principal investigator being member of the Signal Transduction Society. In 2022, the STS Science Award will be donated with a sum of 1500,- Euro.

The jury board consisting of the STS council and STS advisory board members will evaluate the applicants’ scientific achievements and background in general and discuss the meeting contributions in detail in order to finally take their decision on the awardee.

GBM-Innovation-Award for Young Scientists 2022

Each year on the occasion of the STS Joint Meeting “Signal Transduction - Receptors, Mediators and Genes”, the Society for Biochemistry and Molecular Biology/Gesellschaft für Biochemie und Molekularbiologie e.V. (GBM) announces the GBM-Innovation-Award for Young Scientists, donated with EUR 500,–.

The prize will be granted to a young scientist (diploma, master, MD or PhD student or post doc within their first years) who is developing or has developed a novel and innovative method, which might be attractive for all of us. The work has to be submitted as an abstract to the STS-Meeting and must be presented also as a poster, even if the abstract is selected for oral presentation. The awardee will be announced at the Award ceremony. Awards can only be received personally.

The award jury consisting of the speakers of the GBM-Study Groups “Biochemical Pharmacology and Toxicology” and “Receptors and Signal Transduction” will select appropriate candidates.

STS travel stipends

In 2022, the STS decided to award ten young scientists travel stipends (300 EUR each).

For more details, please also refer to the Prizes / Travel grants section of our website.

Poster Prizes

Five poster prizes will be awarded during the meeting. The candidates will be selected by the chair people of the different sessions.

Awards will be made payable by cheque and must be cashed latest by December 31st 2022 (expiration date of the cheque).

STS Honorary Medal 2022

No medalist in 2022

Important Info: Due to irresolvable scheduling conflicts, the nominee will not be able to attend this year's meeting for an in-person medal ceremony. Since the STS considers it a key requirement for the award ceremony that the medalist be present at the meeting as an inspiring example especially for the young scientists, there will therefore be no award winner in 2022.

The STS honorary medal represents the most prestigious award of the STS. In 2017 the International Journal of Molecular Sciences (IJMS) became the co-sponsor. The medal is presented every year to an outstanding scientist who inspired scientists all over the world to work on receptors, mediators or genes involved in signal transduction processes. The Medal Ceremonies with informative Laudations and the Medal Award Lectures are meanwhile established highlights of the conference.

A list of Past Recipients of the STS Honorary Medal is available.
