Your brain begins as a single cell. When all is said and done, it will house an incredibly complex and powerful network of some 170 billion cells. How does it organize itself along the way? Cold ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...

For decades, scientists viewed the genome of a newly fertilised egg as a structural 'blank slate' – a disordered tangle of ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature.

European XFEL reveals hidden cages inside eggs. Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature. Packed with proteins and fats, ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

Even though most people back away quickly when they see a huge wasp’s nest, you can’t deny that these are amazing creatures. The video below captured one of the more elusive intricacies of wasp ...

For the first time, scientists have identified genetic variants that increase the risk of aneuploidy, in which cells have an abnormal number of chromosomes. Aneuploidy in egg cells can lead to ...
