Cells are the smallest unit of life and the building blocks for all organisms. Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell ...

For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important ...

When cancer cells are physically squeezed, they mount an instant, high-energy defense by rushing mitochondria to the cell nucleus, unleashing a surge of ATP that fuels DNA repair and survival. This ...

Animal cell and molecular biology examines how cells are built, how they process information and energy, and how they respond to their physical and chemical environments. At its heart is the cell ...

Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that ...

Researchers at the Francis Crick Institute have shown that the "pacemaker" controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue structures, as in the case of metastasis. DNA would normally ...

Back 2.8 billion years ago, while Earth shifted its plates to make new continents and violent volcanoes produced new crust, life crafted a novel invention of its own. 1,2 At first, the nucleus was ...

Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane. This new 'gateway into the ...
