Background: Accumulating evidence supports a positive correlation between the presence of antiphosphatidylethanolamine (aPE) autoantibodies and clinical symptoms of antiphospholipid syndrome (APS). However, there is a lack of standardized ELISA-based method for detecting aPE. The current study was conducted to investigate the dependence of aPE ELISA on lipid concentration and composition of PE antigens. Methods: A range of ELISA conditions were examined by varying the concentrations of egg PE and by substituting egg PE with combinations of synthetic DOPE and DSPE. The physical properties of the synthetic PE species were also characterized. Results: Our data indicated that there are different optimal …

Although it is known that animals attend to the vocalizations of others (referred to as eavesdropping), what has been missing, or at least left experimentally unproven, until now is whether animals can learn new associations between a signal and a threat. Here Magrath and colleagues (Current Biology, 25(15), 2047–2050, 2015) have for the first time conducted a field experiment that demonstrates just this: superb fairy-wrens learned to associate a novel vocalization with a predator.
