An improved ink for colon tattoos

The colon might be the last place people would consider getting a tattoo, but endoscopic tattooing is an important medical technique for marking colorectal lesions for surgery or follow-up. Today, scientists report a next-generation ...

Advances in micro-computed tomography

Researchers in biomedical physics and biology have significantly improved micro-computed tomography, more specifically imaging with phase contrast and high brilliance X-ray radiation. They have developed a new microstructured ...

Stratospheric balloons listen in on ground activity

Earthquakes, volcanic eruptions, and even severe weather events produce a medley of low-frequency infrasound waves below the range of human hearing. Researchers can investigate these sounds to gain a deeper understanding ...

Frizzleds are dynamic, molecular machines

Maria Kowalski-Jahn and Hannes Schihada, two postdocs in the Schulte laboratory, have used a novel technology of fluorescently labeling receptors with a minimally invasive technique and detecting structural rearrangements ...

Modern simulations could improve MRIs

Gadolinium-based contrast agents, the gold standard in magnetic resonance imaging (MRI) to determine the health of a patient, can be improved, according to Rice University engineers who are refining models they first used ...

Gd-doped nanoclusters help imaging of early orthotopic cancer

To realize precise diagnosis of early-stage cancer for effective treatment and better prognosis, high-resolution magnetic resonance imaging (MRI) is indispensable with the help of contrast agents. Iron-oxide-based T2 MR ...
