Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.

As chemists tie the most complicated molecular knot yet, biophysicists create a “periodic table” that describes what kinds of knots are possible.

Renee Reijo Pera has spent decades uncovering how the timing of embryonic development contributes to health and disease.

By measuring mechanical forces inside an embryo for the first time, researchers have shown how a physical “jamming” mechanism assists development.

Machine learning techniques are commonly based on how the visual system processes information. To beat their limitations, scientists are drawing inspiration from the sense of smell.

Once again, body cells reveal unexpected plasticity: In a newly discovered type of wound healing, which some researchers call “paligenosis,” adult cells revert to a more fetal state.

Evolution may have coopted an ancient metabolic mechanism to set social insects on the path toward one of the most puzzling behaviors found in nature.

Some species have the equivalent of many more than two sexes, but most do not. A new model suggests the reason depends on how often they mate.

A controversial theory suggests that perception, motor control, memory and other brain functions all depend on comparisons between ongoing actual experiences and the brain’s modeled expectations.
