Diabetes affects millions of Americans, and many don’t even realize they have it. Instead of relying on costly and time-consuming lab tests, scientists at Penn State have developed a breath sensor that can detect diabetes and prediabetes within minutes by measuring acetone levels. Built from laser-induced graphene and zinc oxide, the sensor is lightweight, inexpensive, and designed to overcome challenges like humidity in exhaled breath.

Scientists have uncovered how exercise suppresses appetite through a surprising molecular pathway. A compound called Lac-Phe, produced during intense workouts, directly quiets hunger neurons in the brain while boosting appetite-suppressing ones, causing mice to eat less without side effects. This discovery reveals a natural mechanism linking physical activity and reduced hunger, paving the way for new obesity treatments.

Despite strong evidence that salt substitutes can safely lower sodium intake and reduce high blood pressure, very few Americans use them. A new analysis of nearly 20 years of national health data found that usage peaked at just over 5% and then declined, even among those with hypertension. Researchers say this represents a major missed opportunity to improve heart health, especially since salt substitutes are inexpensive and effective.

For decades, scientists have puzzled over why smoking makes Crohn’s disease worse but seems to protect people from ulcerative colitis. Now, researchers at RIKEN have discovered that smoking creates metabolites like hydroquinone that allow mouth bacteria—especially Streptococcus mitis—to settle in the gut. These bacteria spark an immune response that reduces inflammation in colitis but worsens Crohn’s. The findings open the door to new therapies using probiotics or targeted compounds that mimic smoking’s protective effects without its deadly risks.
