New research explores newborn in-hospital weight loss

...he first few days, loss of 5-7% of birth weight is considered physiologically appropriate. Newborn feeding experiences may be critical in metabolic imprinting and may factor into adult weight. The most influential predictor of weight loss in newborns is the type of infant feeding, conclude the authors. Furth...

The evolutionary foundation of genomic imprinting in lower vertebrates

These results indicate that the evolutionary foundation of genomic imprinting exists in l...

Environmental epigenetics has potential for preventing and treating disease

The authors previously demonstrated that imprinting evolved anywhere from 230 to 150 million years ago, arising in mammals with the evolution of the placenta. They note that the expression of imprinted ...
