Cells are the basic units of life — but when it comes to cells, if you think basic means simple, think again. Cells are complicated, with many millions of biochemical reactions per second seething ...

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling.

There is exciting potential for technology that enables on-demand, precision control of cell functions within tissues, for both basic studies and for externally controllable cell therapies. Current ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

Just as the human body relies on organs such as the heart, lungs and intestines to carry out specialized functions, cells contain organelles (‘little organs’) that carry out essential processes and ...
