Researchers have identified a previously unknown mechanism that drives the death of inner ear hair cells, the tiny sensory ...

Other cells, such as glial cells, support the function of neurons. Neuroscience has often painted glial cells as the glue ...

Scientists have developed a new imaging technique that uses a novel contrast mechanism in bioimaging to merge the strengths ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

As humans and other animals grow old, our cells modify their endoplasmic reticulum (ER) – an extensive transport system that plays a critical role in various biochemical processes such as protein ...

Mitochondria possess their own mRNA translation system, mediated by specialized mitoribosomes. Dysregulation of mitochondrial translation disrupts metabolic homeostasis and is linked to various ...

A surprisingly small detail in the skin may play an outsized role in how young skin looks and how well it repairs scars. Researchers say the clue is a microscopic structure found in humans, pigs, and ...

MIT researchers have found that tiny DNA loops persist even as cells divide, challenging the idea that the genome resets during mitosis. These structures may explain how cells retain genetic ...

The epicardium, previously viewed as a passive outer layer around the heart, is now recognized as an essential component in development, regeneration, and repair. In this review, we explore the ...

Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell's lysosomes. The breakthrough ...

Researchers have uncovered a shared brain cell breakdown mechanism behind Alzheimer’s and Parkinson’s diseases, revealing how two different proteins can disrupt neurons in the same devastating way.

Using single-cell transcriptomic data from adult mouse inner ear hair cells, the authors identify the differences and similarities of the four hair cell types. They make an important finding: that ...
