THE ONGOING MYSTERY OF HICCUPS

This week: It’s time to move beyond "weight loss" as a singular health goal; an unlikely strategy for Alzheimer’s screening; why riding a bike might boost mental well-being; the evolutionary origins of hiccups; the macronutrients your body needs.

PHOTOGRAPH BY MANAN VATSYAYANA, AFP/GETTY IMAGES ​Does losing weight lead to better health? Not necessarily If the number on your scale qualifies you as overweight or obese, you should shed those extra pounds to become healthier—right? It’s a belief many hold, but one science doesn’t support. "Society has this false assumption that higher body weight equals poorer health," says one expert.

New research has connected physical changes in a region of the eye called the retina to what happens in the brain during Alzheimer’s. If clinicians could reliably diagnose the disorder before symptoms appear, they could try interventions to slow down the disease's progression.

THE ONGOING MYSTERY OF HICCUPS

PHOTOGRAPH BY THREE LIONS, GETTY IMAGES Hiccups have roots deep in our evolutionary history. Yet after millions of years, tens of thousands of years of human problem-solving, and decades of modern medicine, their origin and purpose is still largely opaque. Here’s what scientists are learning about how this reflex evolved—and maybe how to stop it. WHAT THE SCIENCE SHOWS ACHOO! These photos show how far a sneeze can launch germs +

THE BRAIN ON BICYCLING

PHOTOGRAPH BY IMGORTHAND / GETTY IMAGES Science has repeatedly proven that physical activity contributes to improved mental health. And while any exercise helps, a growing number of studies reveal bicycling is among the activities that might provide even more of a mental health boost, especially for children. "Our research shows that kids who get out for a bike ride at least once a week report higher levels of mental well-being," says one scientist. 7 IDEAS TO GET YOUR KIDS PEDALING
