How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

The first lineage decisions in mammalian embryonic development are made shortly after a wave of transcriptional activation that acts as a wake-up call for the sleeping embryonic genome to claim the ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

Genes are transcribed from DNA into RNA, which is then processed in various ways before being translated into proteins. RNA molecules get edited or spliced, and certain sequences might be removed ...

Researchers are studying development of human pre-implantation embryos in an effort to improve success of embryo growth and development.

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 ...

Temperature and humidity are critical for successful incubation; optimal temperature is around 99.5°F (37.5°C) and humidity levels should range 40-50% during incubation and 65-70% during hatching.

Consider the crustacean Parhyale hawaiensis, a tiny crustacean with some interesting attributes. “It’s been called a ‘living Swiss army knife,’” said Dillon Cislo, the lead author of a study that ...

A test deployed in many fertility clinics to assess the viability of embryos for use in IVF is likely to overestimate the ...
