Saturn's rings in a supercomputer

Scientists discovered that the size of particles doesn't matter for ring formation and that the abundance of larger particles drops off due to surface forces. The team's model showed that the size distribution in planetary rings is universal, supporting a hypothesis that it follows the same laws as Saturn's rings.

Observing live energy production by malignant cells

Researchers developed a biosensor to measure Mitochondrial Pyruvate Carrier (MPC) activity in malignant cells, finding low MPC activity compared to healthy cells. Treating cancer cells with a new compound restored normal MPC activity, suggesting the carrier's dysfunction is responsible for its inactivity.
