Scientists first read the human genome, a three-billion-letter biological book, in April 2003. Since then, researchers have steadily advanced the ability to write DNA, moving far beyond single-gene ...

Mendel’s monastery garden experiments went largely unnoticed during his life, but their implications would ripple through ...

In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists. Now, ...

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is linked to faster brain aging. When you purchase through links on our site, we ...

A gene on the X chromosome revs up inflammation in the female brain, which may explain why rates of multiple sclerosis are higher in women than in men, scientists suggest. When you purchase through ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Researchers have uncovered a "selfish" X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. "Researchers have known about these selfish genes ...

Researchers have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't produce enough ...

I married a tall woman out of love, partly from genetic ambition. I figured we’d gift our kids a vertical advantage. It turns out that Mother Nature and Friar Mendel’s peas don’t translate into ...

Telomeres, stubby strips of DNA that cap the ends of chromosomes, predict the risk of heart disease, a new study shows. Middle-aged men with shorter telomeres are more likely to develop the disease, ...
