The brutal attack on Ukraine by the Russian Federation has shocked the world. While the world works to end the violence and help refugees, as a scientific journal, our thoughts are also with those in the scientific community who are directly or indirectly impacted by the war. We have been inspired by and applaud the labs around the world that have opened their doors to displaced scientists and remain committed to supporting scientists, whoever and wherever they are. Because science requires collaboration and trust, we urge the scientific community to continue efforts like this and to remain united, especially in times as difficult as these. In this Voices piece, we feature short comments from scientists from Ukraine and scientists from Russia. This small sampling is far from exhaustive, but our sincere thanks go to those scientists who were willing to share their thoughts on this volatile and emotionally charged situation; the views expressed are those of the contributors alone. We join the world in hoping for a swift resolution to the conflict, for the good of humanity.
