From the evidence of karyomeres in animal cells, the nucleus is regarded as a compound structure, and it was further suggested that the spindle is also compound, the real unit in mitosis being a ...

Electronic structure can be shown as a list of numbers or as a diagram. Take lithium for example. The diagram above shows each shell as a circle around the nucleus, with each of the three ...

However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus ... Beyond the ladder-like structure described above, another ...

After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than ...

Scientists uncover how the nucleolus, a tiny structure within cells, may control aging and lifespan, opening new ...

Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be ...

The results confirmed the original anomaly, but thanks to new nuclear theory calculations from researchers at TU Darmstadt, ...

When world-leading teams join forces, new findings are bound to be made. This is what happened when quantum physicists from ...

Researchers are particularly interested in 3D genome subcompartments because they reveal where chromosomes are located spatially inside the nucleus ... cellular structure and function across ...

The three-dimensional structure of DNA in the nucleus is stabilized by the cohesin ... a mutation leading to the loss of ...
