Study on bizarre rodent genetics solves a mystery and reveals another

Open up Scott Roy's Twitter bio and you'll see a simple but revealing sentence: "The more I learn the more I'm confused." Now the rest of the scientific world can share in his confusion. The San Francisco State University ...

Study reveals new clues about the architecture of X chromosomes

Researchers at Massachusetts General Hospital (MGH) have uncovered new clues that add to the growing understanding of how female mammals, including humans, 'silence' one X chromosome. Their new study, published in Molecular ...

How chromosomes evolve to create new forms of life

3-D printing is a universal process in the sense that pretty much any part that can be drawn up in a CAD program can be printed, at least within a certain resolution. Machining a part on a mill or lathe, while having the ...

The bull Y chromosome has evolved to bully its way into gametes

In a new study, published Nov. 18 in the journal Genome Research, scientists in the lab of Whitehead Institute Member David Page present the first ever full, high-resolution sequence of the Y chromosome of a Hereford bull. ...

A gel for dosage compensation

Human females have two X chromosomes, and males only one. This chromosome imbalance also extends to other branches of the animal kingdom. Interestingly, the humble fruit fly has devised a different way to 'equalize' these ...

The birth of a male sex chromosome in Atlantic herring

The evolution of sex chromosomes is of crucial importance in biology as it stabilizes the mechanism underlying sex determination and usually results in an equal sex ratio. An international team of scientists, led by researchers ...
