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 ...

Researchers have uncovered a surprising molecular chain reaction in the brain that may play a role in some forms of autism.

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, ...

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

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

Innate immune sensors – known as pattern recognition receptors (PRRs) – detect specific molecular components of bacterial or ...

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

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 ...

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

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?

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 ...
