Pancreatic cancer progression is driven by glutamatergic pseudo-synapses between sensory neurons and tumor cells, where glutamate activates and increases expression of GRIN2D NMDA receptors. More NMDA pores generate larger calcium signaling that enhances malignant behavior.

African Americans, women, rural dwellers and less-educated people are more likely to distrust scientists. They’re also less likely to be scientists. That’s not a coincidence, new research found.

Not having offspring key to long life: research shows blocking reproduction can increase the lifespan of males and females of 117 different mammal species. In males, only castration extends lifespan — not vasectomy. In females, lifespan increased after several different forms of sterilisation.

Humans made fire 350,000 years earlier than previously thought. The control of fire provided warmth, light, protection from predators, and allowed humans to process a wider range of foods, supporting better survival, larger groups and freeing up energy to fuel brain development.

People who identify as politically conservative are more likely than their liberal counterparts to find “slippery slope” arguments logically sound. This tendency appears to stem from a greater reliance on intuitive thinking styles rather than deliberate processing.

Antarctica's only native insect is already ingesting microplastics, even in one of the planet's most remote regions. In Belgica antarctica, ingestion was rare and non-lethal, yet larval exposure reduced lipid stores in a dose-dependent manner, confirming contamination in natural habitats.
