Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...
Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.
Aging cells stage a dramatic renovation project. Within the first three days of reaching adulthood, they start dismantling up to 70% of one of their most important internal structures. Scientists just ...
In a quiet lab at Utrecht University, researchers have built a tool that lets you watch one of life’s most serious crises unfold in real time. Inside every cell, DNA breaks, repairs, and sometimes ...
No one has yet created a fully functioning artificial cell. But a research team at Aarhus University has taken a step in that direction: They have equipped artificial cells with tiny motors inspired ...
Neurons placed inside engineered living bodies built from frog cells self-organize, become active, and reshape movement ...
Within tumors in the human body, there are immune cells (macrophages) capable of fighting cancer, but they have been unable to perform their roles properly due to suppression by the tumor. KAIST ...
Diamond nanoparticles containing nitrogen-vacancy centers can now monitor cellular metabolism in real time, targeting specific organelles while tracking particle movement inside living cells.
