In fact, Asgard archaea appeared almost heaven-sent for research: they turned out to be a missing link between archaea and eukaryotes -- that is, between archaea and organisms whose cells contain ...

Scientists are currently debating the events leading to the appearance of plastids in eukaryotic cells. Where did plastids originate? Their origin is explained by endosymbiosis, the act of a ...

Two weeks after a human egg is fertilized, primordial germ cells (PGCs), which develop into sperm and eggs, are formed. In six to 10 weeks after fertilization, PGCs differentiate into pro ...

Pasteur went on to argue that this same bacteria could cause disease. To describe these ideas, he coined the phrase ‘Germ Theory’. But someone was hot on Pasteur’s heels… Oh ja!

The authors have generated important resources such as a reference dataset of early primate development by utilizing single-cell transcriptomic technology together with induced pluripotent stem cells ...

The outbreak’s point of origin is still unknown ... these spores migrate to the small intestine and invade intestinal cells to produce more spores. As the parasitic cells grow, they inflict ...
