The findings could represent a novel mechanism for relieving inflammatory pain.

Defects in the response to fire-generated karrikins turn out to be responsible for root anomalies that were previously ascribed to other plant hormones.

About one-quarter of the hundreds of genes on the inactivated X chromosome in XX cells manage to escape that silencing, at least some of the time.

The ChoanoVirus genome codes for rhodopsin, perhaps giving its choanoflagellate host extra energy-harvesting capabilities.

A handful of clinical trials are underway to find out whether drugs that target senescent cells can slow the ravages of old age.

When X-linked genes evade silencing on the “inactive” chromosome in XX cells, some protect women from diseases such as cancer, but others seem to promote conditions such as autoimmunity.

The accumulation of zombie-like cells seems to accelerate aging and promote aging-related disease. Researchers are trying to figure out how.

Three-dimensional polymer matrices offer researchers a new representation of the extracellular matrix that can be used to study the growth of cancer cells.

Contrary to popular thinking, the period of arrested development is an active state of maintaining muscle integrity.

Scientists have developed a tissue-clearing protocol that allows them to peer into entire, transparent human organs.

Using advanced microscopy and imaging techniques, scientists have revealed new parts of the human body and overturned previous misconceptions.

The last few years have yielded new insights into human anatomy. Explore this interactive graphic to learn about some of these discoveries.  

The Vanderbilt University professor was awarded a Nobel Prize for his discovery of epidermal growth factor.

The functional, respiring organelles appear to be present in the blood of healthy people, but their function is yet unclear.

A mouse model of autism and postmortem brains of autistic individuals showed a lack of mature oligodendrocytes and less myelination than controls.

Planarian flatworms grow to double their normal size when scientists inhibit a gene that suppresses growth.

The genetically modified bacteria spark an RNAi response in the parasite that leads to self-destruction—and perhaps a path to combatting colony collapse disorder.

Two papers reveal that many commonly used research antibodies don’t bind as believed, highlighting the need to validate these reagents before use.
