Journal of Clinical Ultrasound, EarlyView.Fetal ear length (FEL) correlates with gestational age and may help detect chromosomal anomalies. This study developed a nomogram for a Southern European population, showing high measurement reliability. While FEL ≤ 5th percentile increased anomaly risk, its moderate sensitivity and specificity limit clinical utility.

Emerging patterns of CO2 : O2 dynamics in rivers and their link to ecosystem carbon processing
Limnology and Oceanography Letters, EarlyView.Abstract Aquatic metabolism is reflected in the dynamics of dissolved oxygen (O2) and carbon dioxide (CO2) concentrations. Thus, paired measurements of CO2 and O2 concentrations can capture the metabolic characteristics of an ecosystem, with promising results in lakes.
