A new study by UC San Diego's Scripps Institution of Oceanography reveals a startling finding: More than 90% of popular freshwater game fish in Southern California contained an introduced parasite capable of infecting humans. The NIH-funded study suggests that these parasites pose a previously unrecognized public health risk in the United States.

Researchers at the University of Pittsburgh discovered that specific brain white matter features in 3-month-old infants can predict how their emotional responses and regulation abilities will develop by 9 months. Higher neurite dispersion in brain connections was linked to increased negative emotionality, while greater connectivity within executive control regions predicted better positive emotions and self-soothing abilities.
