Geochimica et Cosmochimica Acta, 1998
Patterson (1956) established that the age of Earth is close to that of meteorites. Over the last 20 years, workers argued for younger age for core differentiation based on Pb-Pb model ages and tungsten isotopic data and for gas retention based on I-Xe modeling.

Young maternal age and preterm birth
Paediatric and Perinatal Epidemiology, 2003SummaryThe association between young maternal age and preterm birth (PTB) remains controversial. In some studies the association disappeared after controlling for socio‐economic and reproductive factors, thus indicating that social disadvantage rather than biological factors may be the explanation.

Suppressor Lymphocytes in Young and Aged Humans
The Journal of Immunology, 1977Abstract Using human peripheral lymphocytes activated by concanavalin A (ConA), we observed suppression of the normal lymphocyte response to mitogens and allogeneic cells. The suppressive effect requires at least a 24 hr activation period of lymphocytes with ConA and is dose dependent.

Leaving aside chronological or biological dimensions of age, this study

Epidemiology, 1995
Some studies indicate that children born to younger mothers are at higher risk for wheezing or asthma. I conducted a case-control study that included 457 new cases of asthma in 3- and 4-year-old children and an equal number of controls. I found that, in comparison with children of mothers 30 years of age or older, children of mothers age 26-30 years ...
