...t the male used," said Alberts. "But we are led to conclude from our studies that males use multiple cues to identify their offspring -- including perhaps pheromones, physical and behavioral resemblance, or the amount of mating time with the female.

In addition, Akt2 is critical for the adaptive response of pancreatic b cells to insulin resistance and hyperglycemia. ...Immerge BioTherapeutics announces new findings addressing key safety risk in xenotransplantation
