Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...
Meanwhile, medical research has changed. We can now study human disease using patient-derived cells, human organoids, advanced imaging and computational tools that reveal mechanisms we could not see ...
Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...
King's College London researchers have created a unique collection of human stem cell models that could help to uncover why ...

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 ...
For much of the 20th century it was thought that the adult brain was incapable of regeneration. This view has since shifted dramatically and neurogenesis – the birth of new neurons – is now a widely ...
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 ...
Researchers recently developed a bone marrow model to study how the body generates cells. Interestingly, this model is the first of its kind to be developed entirely from human cells. Not only can ...
The brain is shielded from many substances by the blood-brain barrier, but this shield is not impenetrable. There are immune cells in the brain called microglia that can respond to potential invaders ...
