New research has mapped the cell types that specialize to form reproductive organs in both sexes, identifying key genes and ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

A growing number of new studies have found that, at least for some cells, death isn’t the end, but the beginning of something wholly unexpected.

The idea that the human body completely regenerates itself every seven years is a widely shared “fact.” But how much truth is there to this claim? While the body is constantly renewing itself, the ...

A newly identified class of RNA molecules has been discovered in bacteria living inside the human body. These circular ...

Researchers discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right “tracks” during cell division. Instead of acting like a motor, it works more like ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...

Aging is the process of getting older. In biology, aging refers to how, over time, the cells in our bodies wear out or get damaged. They no longer work as well as they used to. Some visible signs of ...

Electrically stimulating key cells in the immune system could "reprogram" them to reduce inflammation and encourage faster and more effective healing in the body. This is the discovery of scientists ...

The latest chemistry news, including important research advances, business and policy trends, chemical safety practices, career guidance, and more. Current approved CAR T-cell therapy treatments rely ...

A groundbreaking experiment transforms skin cells into egg-like cells, offering hope for infertility treatments amidst ...
