Just as life pulsates in big vibrant cities, it also prospers in crowded environments inside cells. The interior of cells is ...

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 ...

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 ...

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 ...

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 ...

Over the past decade, there have been scattered reports of mammalian cells’ own DNA being found in the cytoplasm, mainly in the context of disease and aging. While it is not unusual to find DNA from ...

Subscribe to our newsletter for the latest sci-tech news updates. They found that the cytoplasm inside the worms was significantly more crowded and compartmentalized than in single-celled yeast or ...

Gynodioecy is the co-occurrence of females and hermaphrodites in populations. It is usually due to the combined action of cytoplasmic male sterility (CMS) genes and nuclear genes that restore male ...

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 ...

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 ...
