Researchers at Cardiff University have uncovered how a particularly severe form of DNA damage arises—shedding new light on ...

When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

A study explains how broken DNA during cell division can trigger chromoanasynthesis when two repair pathways combine, causing ...

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes.

Researchers at a lab in Kansas City believe they have made a breakthrough discovery in understanding infertility.

Autism spectrum disorder (ASD) is a neurological and developmental condition that can be diagnosed at any age, although the symptoms tend to appear in the first two years of a patient's life. ASD can ...

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

The cloudberry, a popular northern dessert berry, reveals a surprising genetic origin after a study deciphers its complex evolution.
