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 ...

An international team of scientists has unveiled the most comprehensive model yet that explains how cells control the flow of ...

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 ...

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.

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 ...

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 ...

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 ...

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 chromosome theory of heredity, developed in 1902–1904, became one of the foundation stones of twentieth-century genetics. It is usually referred to as the Sutton–Boveri theory after Walter Sutton ...

As cells get older, they don’t lose their hair or teeth. Instead, they lose control over their nuclear membrane, the protective barrier that encases DNA in the nucleus, concludes a study published in ...

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 ...
