Jumping genes threaten egg cell quality

A woman's supply of eggs is finite, so it is crucial that the quality of their genetic material is ensured. New work from Carnegie's Marla Tharp, Safia Malki, and Alex Bortvin elucidates a mechanism by which, even before ...

Rewinding development: A step forward for stem cell research

Scientists at the Danish Stem Cell Center, DanStem, at the University of Copenhagen have discovered that they can make embryonic stem cells regress to a stage of development where they are able to make placenta cells as well ...

Computer models provide new understanding of sickle cell disease

Computer models developed by Brown University mathematicians show new details of what happens inside a red blood cell affected by sickle cell disease. The researchers said they hope their models, described in an article in ...

New insight into primate eye evolution

Researchers comparing the fetal development of the eye of the owl monkey with that of the capuchin monkey have found that only a minor difference in the timing of cell proliferation can explain the multiple anatomical differences ...

Research in cellular memory

How do fetal cells know what cell types to become? Why do cells in the adult body sometimes forget what they are and develop into cancer cells? These are some of the questions intensively investigated within the research ...
