Does Chinese research hinge on US co-authors? Evidence from the China initiative

Launched in November 2018 by the Trump administration, the China Initiative was meant to "protect US intellectual property and technologies against Chinese Economic Espionage". In practice, it made administrative procedures more complicated and funding less accessible for collaborative projects between Chinese and US researchers. In this paper we use information from the Scopus database to analyze how the China Initiative shock affected the volume, quality and direction of Chinese research. We find a negative effect of the Initiative on the average quality of both the publications and the co-authors of Chinese researchers with prior US collaborations. Moreover, this negative effect has been stronger for Chinese researchers with higher research productivity and/or who worked on US-dominated fields and/or topics prior to the shock. Finally, we find that Chinese researchers with prior US collaborations reallocated away from US coauthors after the shock and also towards more basic research

Saharan Dust and Florida Red Tides: The Cyanophyte Connection

Prediction of the consequences of harmful algal blooms for humans and other vertebrates is constrained by an inadequate understanding of the factors that promote their initiation. A simple exponential growth model of net production is used for analysis of four time series at different sampling intervals over similar to 40 years of red tide strandings, associated fish kills, and concomitant dust loadings on the West Florida shelf. at least large summer blooms of a toxic dinoflagellate Gymnodinium breve appear to be primed regularly by an aeolian supply of nutrients. Wet deposition of Saharan mineral aerosols may alleviate iron limitation of diazotrophic cyanophytes, which in turn fuel the nitrogen economy of red tides in the eastern Gulf of Mexico. Vagaries of the wind-induced circulation and of selective grazing pressure on phytoplankton competitors within phosphorus replete coastal waters then determine each year the residence times for exposure of G. breve-mediated neurotoxins to fish, manatees, and humans along the southeastern United States
