In their quest for safe, mass-producible artificial blood, geneticists have long struggled. Our limited knowledge of genetic pathways that govern the development of blood has kept us from producing ...

Tiny plastic particles, from the micro- to nanoscale, have been routinely detected in water, soil, air, aquatic species, and humans in recent years. As concerns grow over their potential impact on the ...

Polystyrene nanoparticles are widely used in packaging, but their effects on organisms are unclear. Very little was known about how they affect blood cell development until now. Red blood cells are ...

Almost all animal species -- including humans -- have blood cells, but between different species our blood tells different ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...
