Researchers have developed a method that could make magnetic resonance imaging -- MRI -- multicolor. Current MRI techniques rely on a single contrast agent injected into a patient's veins to vivify images. The new method uses two at once, which could allow doctors to map multiple characteristics of a patient's internal organs in a single MRI. The strategy could serve as a research tool and even aid disease diagnosis. Watch the video here.

Scientists have observed that more aerobically fit individuals have better memories. To investigate this phenomenon, they used magnetic resonance elastography (MRE), which measures the firmness and elasticity of organs, and found that fit individuals had a firmer, more elastic hippocampus—a region of the brain associated with memory. The method could provide early diagnosis and potential interventions in the initial stages of neurodegenerative disease.

Researchers funded by NIH have developed an imaging method that reveals a much more diverse and flexible DNA-protein chromatin chain than previously thought. The result suggests a nimbler structure to regulate gene expression, and provide a mechanism for chemical modifications of DNA to be maintained as cells divide.

NIH-funded scientists at the University of Florida have discovered a new method of observing the brain changes caused by Parkinson’s disease, which destroys neurons important for movement. The development suggests that fluid changes in a specific brain area could provide a way to track that damage.

A team of bioengineers supported through a Small Business Innovation Research grant from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) has developed a pocket-sized, ultrasound imaging device to aid doctors in accurately placing needles into the lumbar, or lower, spine.

NIBIB-funded researchers have developed a revolutionary 3-D printer that paves the way for direct printing of biomedical devices onto human skin. The printer builds flexible electronic sensors that measure pressure.  They’re expected to improve sensation in prosthetic hands and surgical robotic arms.

“Seeing is believing,” has been taken to heart by researchers as they strive to develop microscopes that will reveal biological structures and processes with increased clarity and detail. Now, researchers funded by the National Institute of Biomedical Imaging and Bioengineering have developed a technique that uses the vibration of chemical bonds to produce specific colors that allow them to simultaneously observe, in cells and tissues, as many as 24 interacting molecules--each with a distinct color.

A metal-free MRI contrast agent has been developed that could be safer for certain patients. The compound contains organic molecules called nitroxides instead of metal and may be used to generate more informative MRI scans of tumors. Read more at MIT News.

Using a larger dataset than for any previous human movement study, National Institutes of Health-funded researchers at Stanford University in Palo Alto, California, have tracked physical activity by population for more than 100 countries. Their research follows on a recent estimate that more than 5 million people die each year from causes associated with inactivity.

A new portable device can quickly find markers of deadly, unpredictable sepsis infection from a single drop of blood. The device is the first to provide rapid, point-of-care measurement of the immune system's response, without any need to process the blood. This can help doctors identify sepsis at its onset, monitor infected patients and could even point to a prognosis. Read more at Illinois News Bureau.
