Origin of a complex life form revealed

Researchers from McGill University have revealed the steps by which two very distinct organisms—bacteria and carpenter ants—have come to depend on one another for survival to become a single complex life form. The study, ...

Epigenetics and cell diversity in the embryo

A research team at the Max Planck Institute for Molecular Genetics in Berlin has explored the role of factors in embryonic development that do not alter the sequence of DNA, but only epigenetically modify its "packaging". ...

Unprecedented single-cell studies in virtual embryo

"How are the many different cell types in the body generated during embryonic development from an egg, which is only a single cell? This is one of the most fundamental questions in biology," explains Dr. Pierre Neveu, group ...

Worms discovered in the brain of lizard embryos for the first time

Researchers have discovered nematodes, or worms, in the brains of lizard embryos. This is the first time they have been found in reptile eggs, and it was previously believed that egg laying prevents parasites from being transmitted ...

How some mammals pause their pregnancies

How do some mammals postpone the development of their embryos to await better conditions for having offspring? A recent study at the UW Medicine Institute for Stem Cell and Regenerative Medicine explored this reproductive ...

Unlocking the black box of embryonic development

Little is known about the molecular and cellular events that occur during early embryonic development in primate species. Now, an internationally renowned team of scientists in China and the United States has created a method ...
