Molecules 2020 Tu Youyou Award—Interview with Winner Prof. Mauro Maccarrone
Tu Youyou Award
Established in honor of Professor Tu Youyou, winner of the 2015 Nobel Prize for Physiology or Medicine for her key contributions to the discovery of Artemisinin, which is used as an antimalarial agent, the Tu Youyou Award is presented bienially to a researcher of any age who has made significant, high-impact contributions to natural product or medicinal chemistry research. Prof. Tu tested the toxicity of her new drug by taking it herself; she put herself in harm’s way in order to produce a compound that would go on to save the lives of millions. Molecules established the Tu Youyou Award in order to highlight and celebrate researchers who, like Tu Youyou, dedicate their lives in various ways to research that improves the lives of others. The Award is given for the originality of the nominee's research, the importance of the work, and the quality of publications. The winner receives 3000 CHF and an engraved plaque.
About 2020 winner
The winner of the Molecules 2020 Tu Youyou Award is
Prof. Mauro Maccarrone.
Mauro Maccarrone is a Professor and Chair of Biochemistry at the University of L'Aquila. He is also the Director of the Lipid Neurochemistry Laboratory at the European Centre for Brain Research (Santa Lucia Foundation, Rome). His group is comprised of four units, and they are highly integrated and have collaborated for more than 15 years (they are located at Tor Vergata University of Rome, University of Teramo, Santa Lucia Foundation, and Campus Bio-Medico University of Rome). Prof. Maccarrone’s research focuses on a novel class of lipid signalling molecules: the endocannabinoids, and resulted in numerous articles published in prestigious journals which have been cited many times. Most importantly, his work has great translational potential and has opened new avenues for the treatment of a number of diseases that altered endocannabinoid functions in a pathogenic capacity. This is an outstanding achievement in a scientific environment that is only becoming more competitive. Please join us in congratulating Prof. Mauro Maccarrone for his commitment and wish him the best in future endeavours. Let’s learn some more interesting facts while listening to the interview!

Book Builder—Compile a Customized E-Book from Your Favorite MDPI Open Access Content
MDPI Books recently released Book Builder, a new online tool to conveniently arrange, design and produce an eBook from any content published in MDPI journals. Book Builder offers two functions: on the one hand (1) Selections, available to every registered user of MDPI; on the other hand (2) Special Issue Reprints, which can be used exclusively by Guest Editors of Special Issues.
Selections
In just a matter of a few clicks, all users are now able to assemble books from MDPI articles and receive instantaneous feedback in the form of a fully produced and compiled book (PDF), which can be downloaded or ordered as print copy. Selections can include any paper published with MDPI, picking and combining content from different journals and special issues.
This way, the user may for example choose to compile an ebook focusing around a particular topic, or assemble articles from a group of others.
We invite you to make yourself familiar with the new tool! The Book Builder can be found here: https://www.mdpi.com/books/book_builder.
Special Issue Reprints
The Book Builder allows Guest Editors of MDPI journals to create a reprint from a successfully completed Special Issue or Topical Collection in book format. If you are a Guest Editor for an MDPI journal, you can use the new tool to create an PDF document which includes all articles published in the Special Issue as well as a book cover and table of contents.
For Special Issues containing a minimum of 5 articles, the Guest Editor can request its publication on the MDPI Book platform. Published reprints are assigned an ISBN and DOI.
In addition to the PDF copy of the Reprint Book, as a token of our gratitude, MDPI offers every Guest Editor one (1) complimentary print copy (via print-on-demand). All contributors benefit from a discount on orders of any additional print copies, to share with colleagues or libraries or others.
In line with our organization's values, MDPI Books publishes all content in open access, promoting the exchange of ideas and knowledge in a globalized world. MDPI Books encompasses all the benefits of open access—high availability and visibility, as well as wide and rapid dissemination. MDPI Books are distributed under the terms and conditions of the Creative Commons Attribution License, meaning as an author you retain the copyright for your work. In addition, with MDPI Books you can complement the digital version of your work with a high-quality printed counterpart.
If you are interested in editing a book volume or series, or have a monograph manuscript to be considered for publication, please submit your proposal online and look at our Information for Authors.
