Despite sharing DNA sequences, monozygotic twins are epigenetically distinct and express different genes, offering a model to better understand diseases.

Scientists identified a nuclear mechanism that distinguishes chronic inflammation from acute inflammation in mice.

A neuronal mechanism pumps the brakes on pain, but failure of these brakes can cause long-lasting pain. The discovery could open new pain treatment paths.

Lac insects carry a yeast-like symbiont that produces a commercially important bright red pigment, revealing insights about insect-microbe symbiosis.

Investigating conserved signaling pathways in different cell types shows that memory is not a unique property of neurons.

Human organs-on-chips and organoids offer new alternatives to animals for drug development, but there is still a long way to go.

Zebrafish hair cells regrow via cyclin gene activity in specific cells, offering clues to future hearing restoration in humans.

A fungal pathogen has rendered the Southern corroboree frog functionally extinct. Can genomics technologies pull the species back from the brink?

A new study identified Parkinson’s disease-associated compounds from earwax, but some scientists remain skeptical.

Current CRISPR guide RNAs are designed based on European reference genomes, leading to false-negative results in cells from people with African ancestry.

In a model of chronic NAD+ depletion that mimics aging, mitochondria are revealed as a rheostat of cellular NAD+ levels.

New research suggests that long-distance running triggers a temporary change in brain structure.
