For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...

Intrauterine growth restriction contributes to high rates of “runt” piglets, which have a lower survival rate after birth.

The 58-year-old wormectomy patient — whose official diagnosis was “O. ovis nasal myiasis with pupation” — apparently had a seriously deviated septum, keeping the interlopers from being sucked into the ...

A Florida IVF clinic is being sold amidst a lawsuit after a woman gave birth to a baby that was not genetically hers. The couple who gave birth to the child filed a lawsuit after genetic testing ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

New stem cell-based embryo model reveals previously unknown communication between early tissues that become the spine and muscles in the central part of the body. From the moment an embryo starts to ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...
