More than 500 million people on three continents are united by the world's largest sea, the Mediterranean. Our strategic geographic location and shared history gives us a common character as well as common challenges. The objective of Mediterranean Researchers' Night - MEDNIGHT is to generate Mediterranean unity, providing awareness about common problems, fostering scientific careers, reinforcing researchers’ commitment and progress, and putting science and scientists at the cornerstone of our future. MEDNIGHT shows the attractiveness and importance of the researchers’ work and professions to the general public, with a focus on young people, carrying out a series of activities framed under the common umbrella of what we have come to call Mediterranean Science, a source of progress and well-being. Mediterranean Science relates to research developed in our territories but also the countless collaborations with other EU researchers. Mediterranean Science is focused on Mediterranean relevant topics according to our culture, way of life or current challenges: History and Heritage, Life and Health, Diet and Nutrition, Sea and Pollution, Climate and Clean Energies, Geology and Biodiversity, Technology and Future. Many online and face-to-face diverse activities will be organised by MEDNIGHT consortium in Messina, Lesvos, Xanthi, Nicosia, Istanbul, Brussels, Monastir, Montpellier, Toulouse, Madrid, Almeria, Orihuela and Tabarca (Main cities) but also Athens, Patras, Limnos, Rhodes, Syros, Eyupsultan, Kadikov, Guardamar, Torrevieja, Santa Pola, Nantes, Larnaca among others. The evolution, expansion and at the same time consolidation of the pillars of MEDNIGHT are being clear, with partners from eight different countries: Spain, Greece, Italy, France, Cyprus, Turkey, Tunisia and Belgium. All together they give solidity to the brotherhood between Mediterranean countries around the culture of science, as opposed to the conflicts that occur in our Mediterranean
