Researchers have created human embryos by taking nuclei from ordinary skin cells, placing them into donated eggs, and ...

Small protein molecules almost do not experience the cytoplasm viscosity while moving within the cell. Scientists have now shown that the effect can be described universally to include ...

The inside of a cell is packed with stuff; from big organelles to small molecules, the cytoplasm is the suspension which contains all those components. Researchers at MIT wanted to know more about how ...

How do genes control us? This fundamental question still remains elusive despite decades of research. Genes are blueprints for proteins, but it is the proteins that actually carry out vital functions.

Inching along, a DNA-preserving mechanism can ultimately defeat the transposon, a danger that jumps. This mechanism is part of a larger process through which tiny pieces of RNA protect reproductive ...

UC Davis researchers tracked the movement of fluorescent particles inside the cells of microscopic worms, providing novel insights into cellular crowding in a multicellular animal. They found that the ...

An international team of researchers has created the most detailed model yet of how cells regulate traffic through the ...

As a tumor grows, it interacts constantly with objects in the surrounding environment, such as blood vessels, signaling molecules and immune cells. Communication between these entities is a two-way ...

The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated ...

HuR, a ubiquitously expressed member of the Hu protein family that binds and stabilizes an AU-rich element (ARE)-containing mRNAs, is known to shuttle between the nucleus and the cytoplasm via several ...

Worn-out proteins, malfunctioning organelles, invading microorganisms: all are swept up by tiny internal "vacuum cleaners" that keep a living cell healthy. If the process, called autophagy, can be ...

Despite its isolation three decades ago, Ebola virus continues to cause periodic outbreaks of severe hemorrhagic fever in humans, and the closely related Marburg virus is responsible for a recent ...
