  • Professor Dan Tracey, Assistant Scientist Stephanie Mauthner, and colleagues have found that a suite of genes in both fruit flies and humans—including one dubbed "smoke alarm"—plays a role in nerve sensitivity. The study could help lead to new drug targets in pain management. [ IU news release | article ]
  • Associate Professor Nick Sokol and collaborators published an eLife article on the relationship between developmental timing and oncogenesis: young neural stem cells are oncogenic but this potential diminishes as animals age and downregulate temporal factors, including the RNA-binding protein LIN-28 and its mRNA targets. [ article ]
