The surprising politics of anti-immigrant prejudice: How political conservatism moderates the effect of immigrant race and religion on infrahumanisation judgements

Attitudes towards immigrants in the UK are worsening. It has been posited that these attitudes may reflect covert racial and religious prejudices, particularly among conservatives. To investigate this, two studies examined the role that immigrant race (Black/White; Study 1) and immigrant religion (Muslim/non-Muslim; Study 2) played in immigrant infrahumanisation judgements, using political conservatism as a moderating variable. There was a moderating effect of political conservatism; however, it was not in the predicted direction. The results of both studies indicated that immigrant race (Black) and immigrant religion (Muslim) predicted greater infrahumanisation when political conservatism was low. Conservatives infrahumanised all immigrants equally (and more than liberals), but liberals were more sensitive to racial/religious biases in their evaluations of immigrants

Transgenic avidin maize is resistant to storage insect pests

Avidin is a glycoprotein found in chicken egg white, that sequesters the vitamin biotin. Here we show that when present in maize at levels of ≥100 p.p.m., avidin is toxic to and prevents development of insects that damage grains during storage. Insect toxicity is caused by a biotin deficiency, as shown by prevention of toxicity with biotin supplementation. The avidin maize is not, however, toxic to mice when administered as the sole component of their diet for 21 days. These data suggest that avidin expression in food or feed grain crops can be used as a biopesticide against a spectrum of stored-product insect pests
