Unlike humans, turtles, lizards and other reptiles – such as crocodiles – do not have sex chromosomes. Their sex is determined based on the environment, which makes them especially vulnerable to ...

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

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Researchers at Sinai Health have found that a critical transition in early human development is regulated not by our genes, but by DNA elements called transposons that can move around the genome. The ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...
