Dietary changes may treat pulmonary hypertension Blood vessels in the lungs aren't like the others in the body. This difference becomes clear in pulmonary hypertension, in which only the lungs' blood vessels stiffen progressively, leading to chronic lung disease, heart failure and death. The underlying reasons for this organ-specific vessel stiffening remained a mystery until researchers made a surprising discovery about these blood vessel cells in patients with pulmonary hypertension -- they're hungry.

New sensor detects errors in MRI scans A new prototype sensor is capable of detecting errors in MRI scans using laser light and gas. The new sensor can thereby do what is impossible for current electrical sensors -- and hopefully pave the way for MRI scans that are better, cheaper and faster.

Diamond dust shines bright in Magnetic Resonance Imaging An unexpected discovery surprised a scientist: nanometer-sized diamond particles, which were intended for a completely different purpose, shone brightly in a magnetic resonance imaging experiment -- much brighter than the actual contrast agent, the heavy metal gadolinium. Could diamond dust -- in addition to its use in drug delivery to treat tumor cells -- one day become a novel contrast agent used for MRI?
