Other PFCs of uncertain origin have been detected in the atmosphere (for references, see ).
In the case of the WOW signal, the possibility of an intelligent source was never ruled out, but no other interesting radio signals from that origin have been detected since.
Trace quantities of organofluorines of uncertain origin have been detected in volcanic eruptions and geothermal springs.
Thousands of genes of potential green algal origin have been detected in diatoms, giving rise to the hypothesis that Stramenopiles have undergone a cryptic secondary endosymbiosis with a green alga before acquiring the red algal endosymbiont (Moustafa et al. 2009).
Despite the difficulty in detecting organics in situ on Mars, small quantities of methane (of abiotic and, possibly, biotic origin) have been detected by the SAM instrument on Curiosity (Webster et al., 2015), and there is evidence for organic carbon in martian meteorites (McKay et al., 1996; Grady et al., 2004; Steele et al., 2012; Lin et al., 2014).
H. capsulatum, the causative fungus of histoplasmosis, also has been isolated from these bats and their guano in the source caves, but neither bats nor guano have yielded the agent in extensive surveys in California, which is regarded as free of the fungus; no cases of indigenous origin have been detected (8 ).
Strong evidence of origin based hiring discrimination has been detected in various developed countries 1 such as Australia (Riach and Rich, 1991), the USA (Bertrand and Mullainathan, 2004) and France (Duguet et al., 2010, 2011).
The possible stem-loop structure located immediately upstream of the origin of the minority strand has been detected in L. migratoria [ 47].
ICAM-3 has been detected on cells of myeloid origin in the synovium, but there is little or no expression of this molecule on the endothelium [ 28].
In addition, functional FPR has been detected in cells of nonhaematopoietic origin, such as lung epithelial cells (Rescher et al, 2002) and hepatocytes (McCoy et al, 1995).
