Columbia researchers found that iron-deficient mice with influenza were unable to produce a key immune protein in the lungs that helps fight infections, even when iron levels returned to normal.
Research by the Concordia Infant Research Lab finds that toddlers raised in bilingual or multilingual homes show no negative effect on vocabulary development from language mixing.
