Cells are constantly on the move, whether in a developing embryo or metastatic cancer. But how do cells adapt to new environments they encounter? Traditionally, scientists have believed that cells ...

Inside every living cell, tiny molecular machines are constantly in motion, shifting shapes, tugging on membranes and shuttling ions from one side to the other. That restless activity does more than ...

How do cells move from A to B through our body to build functional tissues? And how is this process regulated? The answers to these questions are essential – for example, for our understanding of how ...

It has long been known that our bodies derive energy from sugar. Researchers at RPTU University Kaiserslautern-Landau have now discovered that sugar breakdown produces an intermediate product that is ...

Five zebrafish embryos in a tiny drop of water. The yolk sac is clearly visible, with the first two cells located at its tip. Hair, nails, and horns, all made up of keratin, are some of the hardest ...

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they ...

Researchers at Tulane University School of Medicine have discovered that if animal cells gain an extra set of chromosomes, a condition known as polyploidy, they activate a stress signaling pathway ...

A microscopic image shows small red centers connected by networks of branched and straight filaments. The team mixed purified actin monomers with precise concentrations of two nucleation-promoting ...

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body—not only during normal tissue formation and wound healing, but also when tumor cells metastasize. This ...

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 ...
