For decades, scientists have thought they understood the biochemical machinery that causes asthma—inflammation in the lungs that constricts airways and makes it hard to breathe.

Melbourne scientists have revealed how hydrogen is made and used in the human gut. Though infamous for making flatulence ignite, hydrogen also has a positive role supporting gut health.

Today’s GPS smartwatches and other wearable devices give millions of runners reams of data about their pace, location, heart rate and more. But one thing your Garmin can’t measure is plain old physics: How much force is being generated when your foot hits the ground and takes off again.

Researchers led by investigators at Mass General Brigham and Massachusetts Institute of Technology have validated an ingestible capsule in preclinical models for the diagnosis of acute mesenteric ischemia, a condition caused by blocked or reduced blood flow to the intestines. The research is published in Science Robotics.

Ocular fluids provide a window into the health of the eye and the development of various pathologies. However, their study usually involves invasive techniques. “A wide range of eye diseases are being investigated, but the methods for obtaining aqueous humor and vitreous humor, the fluids inside the eye, are highly invasive, which limits their applicability in routine clinical practice,” explains Marta San Roque, Ph.D. student in the Innovation in Vesicles and Cells for Application in Therapy (IVECAT) Group at the Germans Trias i Pujol Research Institute (IGTP).
