A team of researchers affiliated with several institutions in Argentina has found chromosomal evidence of people living in South America as far back as 18,000 years ago. The group has published a paper describing their work ...
Researchers at the Centre for Genomic Regulation (CRG) in Barcelona have identified a potential new diagnostic marker that predicts the successful and efficient development of mammalian egg cells. The findings could pave ...
