Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...
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 ...
When you were first conceived, you were a single cell. From this basic fact, we can extrapolate a few things, most especially that all the cells that make up your body today came (indirectly) from ...
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 ...
In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

Some brain cells resist dementia and scientists finally cracked the code
Researchers have identified a specific protein complex inside neurons that tags toxic tau fragments for destruction, offering the clearest explanation yet for why certain brain cells survive while ...
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 ...

Yeast enzyme helps human cells beat mitochondrial defects
Mitochondrial diseases are severe, often untreatable, and they leave human cells unable to grow normally without outside help. A new study published in Nature Metabolism now shows that a single gene ...
