When implanted into mice, the “pseudo-islets” helped treat the animals’ diabetes symptoms.

Molecular programs can rescue cells already engaged in the process of apoptosis or other forms of programmed cell death.

The lab-made organoids are fully functional, the team reports, and could aid the study of vascular-related diseases such as diabetes.

Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric compartments that act as cauldrons for chemical reactions. Bioengineers are eager to harness the compartments for their own purposes.

These icosahedral structures are composed of proteins with unique geometric properties, which enable bacteria to employ them in a variety of situations.

The physical principles that dictate the formation of these subcellular compartments are simple, but they dictate the organelles’ complex functions.

From making ribosomes to protecting the integrity of the genome, these membraneless compartments play important roles in the cell. Their behavior is rooted in basic physics.

Researchers untangle the multifarious nature of muscle aging. So far, the only reliable treatment is exercise.

Actin rings seal off the ball of cells, aiding in implantation in the uterus. But faults in the process could explain why some pregnancies fail.
