A hidden breathing problem may be behind chronic fatigue’s crushing exhaustion Scientists have discovered that most chronic fatigue patients experience dysfunctional breathing, which may worsen their symptoms. The likely culprit is dysautonomia, a disruption in how the body controls blood vessels and muscles. Breathing retraining, yoga, or biofeedback could help restore proper breathing rhythm and ease fatigue. The findings open a promising new path for managing this long-misunderstood illness.

Half of heart attacks strike people told they’re low risk The study reveals that widely used heart-attack risk calculators fail to flag nearly half of those who will soon experience a cardiac event. Even the newer PREVENT model misclassifies many patients as low-risk. Since most people develop symptoms only within 48 hours of their heart attack, current screening offers little time for intervention. Researchers say earlier detection with imaging could dramatically improve prevention.

New breath sensor detects diabetes quickly and easily 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.

Can zebrafish help humans regrow hearing cells? Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different supporting cells in zebrafish divide and regenerate, offering clues to how mammals might someday tap into similar regenerative powers.

Unusual carbon build-up found in lungs of COPD patients Scientists have discovered that people with COPD have lung cells that contain over three times as much soot-like carbon as those of smokers without the disease. These overloaded cells are larger and trigger more inflammation, suggesting that pollution and carbon buildup not just smoking may drive the disease.
