The California two-spot octopus (Octopus bimaculoides) is native to the coast of California and Mexico and is identified by their bright blue eyespots. (Roger T. Hanlon/Marine Biological Labratory) ...

Researchers from Tokyo Metropolitan University have taken a big step in solving the mystery around why animals evolve sex chromosomes. It had long been proposed that sex chromosomes evolve to reduce ...

As men age, they lose parts of the Y chromosome. Research suggests this may have a greater impact on health than previously assumed.

New techniques to detect Y chromosome genes show frequent loss of the Y in tissues of older men. The increase with age is clear: 40% of 60-year-old men show loss of Y, but 57% of 90-year-olds.

The octopus just revealed another one of its secrets: what determines its sex. University of Oregon researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has ...

A nearly gapless genome sequence of the echidna, an egg-laying mammal with multiple sex chromosomes, helps researchers to track genomic reorganization events that gave rise to a highly unusual sex ...

Here’s a quick reality check: ice cream sales go up in summer, and so do drownings. But no one thinks Ben & Jerry's is a silent killer. It’s correlation, not causation. Yet this same logical ...
