AI reveals hidden bias behind higher amputation rates in minority and rural patients

Why do rural adults and racial and ethnic minorities with vascular disease get major leg amputations more often? A new study out today in Epidemiology uses AI to solve the mystery, finding an unaccounted-for factor that researchers think points to implicit bias in the clinical decision-making process.

Could serotonin supplements become the next hair loss treatment?

Researchers have shown that serotonin directly stimulates dermal papilla cells and promotes hair growth in lab-grown hair follicloids and human hair follicles. The findings suggest serotonin and related compounds could offer new avenues for treating hair loss, though safety and dosing challenges remain.
