Scientists have found the first experimental evidence that an atomic nucleus can harbor bubbles. The unstable isotope silicon-34 has a bubblelike center with a paucity of protons, scientists report ...

There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...

A team has uncovered surprising mechanical behaviors of the nucleus. For years, the nucleus within a cell was thought to be elastic like a rubber ball, deforming and snapping back into shape as the ...

The cell nucleus is considered to be the control center of vital cellular processes, but its material properties continue to puzzle scientists. An international research team has now developed a new ...

One of nature's simplest elements is giving scientists a big headache after new research shows that protons and neutrons in helium atoms are not behaving as theory suggests they should. The mismatch ...

Physicists in Finland have created a pumpkin-shaped atomic nucleus that throws off protons in a rare kind of radioactive decay. The nucleus, lutetium-149, has the shortest half-life of any of a group ...
