Studies show aging men often lose the Y chromosome in some cells, a change now linked to heart disease, cancer, and shorter lifespans.

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 Y chromosome doesn’t seem to do much except determine sex – but its loss in older men might be linked to heart disease, cancer and Alzheimer’s.

New research shows ageing men often lose the Y chromosome in some cells, a change linked to heart disease, cancer, ...

Men tend to lose the Y chromosome from some of their cells as they age — a process once thought to be harmless because the Y carries relatively few genes beyond those involved in male determination.

In June, 2025, the Wellcome Trust announced an ambitious £10 million UK project called the Synthetic Human Genome Project (SynHG) and claimed it “will unlock a deeper understanding of life, leading to ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

Scientists have a solid understanding of what makes up spindles — the cellular machinery that separates chromosomes — but are less certain about how the building blocks of spindles, called ...

In aging research, so-called hallmarks of aging have been established. They describe fundamental biological changes that gradually develop over a lifetime. Exercise is considered a factor that can ...

The election of Donald Trump has been accompanied by an aggressive and ideological attempt to redefine gender and sex, as ...

Ferns, defined by large genomes, high chromosome counts, and pervasive aneuploidy as well as intraspecific polyploid ...
