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 ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

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

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 ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and Stanford University have been able to study the implantation of human ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights ...
