The microbial participants, their interactions, and mechanisms that contribute to satisfying host nutritional and protective needs are largely unknown.

Dr. Strahl will also discuss some of his research on another histone modification, methylation, or the addition of a methyl group.

Until the last few years, most dairy producers would limit the milk intake of calves in order to quickly wean them onto solid feed. Early weaned calves would typically be ready to breed by about 15 months, beco...UCI researchers identify trigger for onset of Alzheimer's, aiding search for new therapies
