Reply to Ferlazzo and Foray: About the Space Pup project

We would like to thank Ferlazzo and Foray (1) for their very important comments and suggestions. We will keep in mind that “scientists should take particular care to justify their methodology and moderate their conclusions.” One concern of Ferlazzo and Foray (1) is that our control experiment entailed exposure to the ground radiation of Japan, rather than to a high natural radiation background (NRB), such as Ramsar. As the authors suggest, it would have been a good idea to expose our control sample to both Ramsar and Japan. When the control radiation level increases from 0.5 mSv/y (Japan) to 70 mSv/y (Ramsar) the difference between space and ground … [↵][1]1To whom correspondence may be addressed.
