In earlier studies from Mennella's laboratory, 4-to 5-year-old children fed hydrolysates during infancy were more accepting of sour taste and aroma sensory qualities associated with ...Chicken litter harbors agents that generate antibiotic multi-resistance, according to UGA study

If we are to ensure mussels persist in the future, Dr. Strayer stresses, "We need to strengthen our understanding of their basic biology while minimizing human activities that have a known negative effect on populations. At the same time, we need to investigate how more subtle human ac...Need sex? It's probably something about stress

When the spores germinate, the genetic machinery goes through a process called meiosis, which repairs and mixes up the DNA from the parents' sperm and eggs.
