Roundup causes high levels of mortality following contact exposure in bumble bees
Journal of Applied Ecology, Volume 58, Issue 6, Page 1167-1176, June 2021., 2021 Surfactants, or other co‐formulants, in herbicides and other pesticides may contribute to global bee declines. We recommend that, as a precautionary measure until co‐formulant identities are made public, label guidelines for all pesticides be altered to explicitly prohibit application to plants when bees are likely to be foraging on them.

Automated system to acquire fluorescence, polarization and anisotropy maps within liquid flows
Journal of Analytical Methods in Chemistry, Volume 24, Issue 2, Page 31-39, 2002., 2002 Maps of polarization and anisotropy can be helpful for flow analysis systems (FIA, CFA, etc.) with reactions dependent on the intermolecular alignment as well as for dispersion control. Maps can be acquired manually, but when a scan over a sample area is required, the acquisition becomes tiresome and has low precision.
