    A biological signature in the blood could be used to aid the early diagnosis of schizophrenia, according to a study published 12 April in Molecular Psychiatry. The results suggest that various circulating immune molecules and metabolites reflect the biological changes that underlie neurological disorders.

  • Researchers engineer mice lacking microRNAs

    Researchers are developing a resource that will allow scientists to engineer mice lacking one of 162 microRNAs — non-coding regions of the genome that regulate gene expression. The results were published 19 April in Cell Reports.

  • Chili pepper protein can alter behavior of mice
