Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

New research is underway to decipher a fascinating biological puzzle—how some animals can naturally discard more than half of their genetic information during embryonic development. This radical ...

Thermal manipulation during incubation represents an innovative approach to enhancing the physiological robustness of avian species in the face of escalating environmental temperatures. By ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

A new finding clarifies how certain proteins work together to direct cells to either specialize or remain pluripotent. This image, generated in the lab of developmental biologist Anna-Katerina (Kat) ...

Most animals, including humans, have bilateral symmetry, which means our bodies are pretty symmetrical. At least on the outside. On the inside, things are different. "If you look at our insides, we ...

Though more than 8 million babies have been born through in vitro fertilization (IVF), 70% of IVF implantations fail. As IVF is becoming a more common route to pregnancy in cases of infertility, there ...

The onset of embryo-specific gene transcription, also known as embryonic genome activation (EGA), is a crucial step in the developmental journey of an organism. Although EGA has been studied to some ...

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body—not only during normal tissue formation and wound healing, but also when tumor cells metastasize. This ...
