Researchers have identified the exact DNA sequence where human chromosomes fuse to form Robertsonian chromosomes, a ...

The images above depict artificially-derived neurons grown in petri dishes, with a human neuron shown on the left. Artificially-derived chimpanzee neurons grow only one or two neurites (connecting ...

The Atlas blue butterfly, with a record-breaking 229 pairs of chromosomes, is helping scientists unravel mysteries of ...

That changed in 2014, when Swedish scientists showed that Y loss in blood cells correlates with how long men live – those who ...

Eggs contain 23 chromosomes needed for human development, which is half the usual number, because the sperm that fertilizes ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 chromosomes ...

More work needs to be done to create viable human embryos, but the method might someday be used in IVF to help infertile people and male couples.

Chromosome sequences from non-human primates have been completely mapped for the first time, marking a significant advancement in genetic research. Scientists funded by the National Institutes of ...

Scientists have confirmed that the Atlas blue butterfly carries the most chromosomes of any animal, with 229 pairs. Unlike duplication, its chromosomes split apart, reshaping its genome in surprising ...

Using a newly developed technique to remove excess chromosomes, a team led by clinical biologist Nuria Marti-Gutierrez of Oregon Health & Science University has created human eggs that can undergo ...
