Unlike virtually every other cell in the human body, the syncytiotrophoblast doesn't have a single nucleus. It has roughly 10 ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and ...

UCSF scientists discover that the spindle, the structure that divides chromosomes equally during mitosis, actually gets stronger when it is stretched.

During pregnancy, maternal and fetal cells migrate back and forth across the placenta, with fetal cells entering the mother's ...

The biological cycle of our existence seems relatively straightforward: we’re born, we live, we die. The end. But when you examine existence at the cellular level, things get a bit more interesting.

Viruses typically aren’t considered ‘alive,’ as many core biological functions are outsourced to their potential hosts. But a newly discovered organism appears to straddle the line between virus and ...

In most animals, stem cells are found in specific regions known as niches. The local environment in human bone marrow tightly regulates stem cells. This local control restrains growth and prevents ...

Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The ...

MIT engineers have challenged a core idea in biology by showing that epigenetic memory is not simply binary. Their research reveals cells don’t just lock genes in an “on” or “off” state. Instead, they ...

For decades, fuel cell innovation has been guided by two main benchmarks: cost per kilowatt and stack durability. These remain important, especially in applications driven almost entirely by project ...
