  We introduce the concept of LabLinking: a technology-based interconnection of
experimental laboratories across institutions, disciplines, cultures,
languages, and time zones - in other words experiments without borders. In
particular, we introduce LabLinking levels (LLL), which define the degree of
tightness of empirical interconnection between labs. We describe the
technological infrastructure in terms of hard- and software required for the
respective LLLs and present examples of linked laboratories along with insights
about the challenges and benefits. In sum, we argue that linked labs provide a
unique platform for a continuous exchange between scientists and experimenters,
thereby enabling a time synchronous execution of experiments performed with and
by decentralized user and researchers, improving outreach and ease of subject
recruitment, allowing to establish new experimental designs and to incorporate
a panoply of complementary biosensors, devices, hard- and software solutions.
