T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the ...

Researchers at the Earlham Institute, the University of Edinburgh and Heriot-Watt University analyzed gut cells to understand ...

Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, ...

A newly identified role for the neuronal MPS shows it controls nutrient uptake by acting as a gatekeeper. Its disruption ...

As inflamed regions of the gut form scar tissue, the space within the gut lumen becomes smaller and more restricted, leading ...

Garlic compounds prolong life and preserve memory and strength in mice, revealing a potential ally against aging.

A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.

German scientists have found that the breakdown of sugar in the body affects not only energy production, but also directly ...

Scientists are investigating how exercise-triggered stress reshapes the cell’s energy systems, and whether those same mechanisms could eventually help counter metabolic disease. Don’t like the gym?

The vagus nerve is a direct link between the gut and brain. Scientists have now used a mouse model to show that changes in gut bacteria could be ... | Microbiology ...

Mass spectrometry is already a powerful tool for determining what kind and how many molecules are present in a given sample. But most instruments still analyze their molecules one or just a few at a ...

Researchers identified TBC1D9B as the off switch for ARL8B, a key regulator of lysosome positioning. This mechanism controls how cells adapt to nutrient stress and maintain metabolic balance.
