Researchers have designed a small voltaic cell that is sustained by the acidic fluids in the stomach and generates enough power to run sensors or drug delivery devices that can reside in the gastrointestinal tract for extended periods. This type of power could offer a safer and longer-lasting alternative to the traditional batteries now used to power such devices. Read more at MIT News.

Researchers at NIBIB have developed a new radiotracer to diagnose prostate cancer and conducted a successful Phase I clinical trial. Prostate cancer is the fifth leading cause of death worldwide and is especially difficult to diagnose. While prostate cancer is relatively easy to treat in its early stages, it is prone to metastasis and can quickly become deadly. In order to plan how aggressively they should treat the cancer, it is important for doctors to know how far the cancer has progressed. NIBIB researchers have attempted to solve this problem by developing a radiotracer that could identify prostate cancer at all stages.

A team of scientists funded by the National Institutes of Health has developed a new tool to monitor under a microscope how cells attach to one another. Studying adhesion events can help researchers understand how tissues grow, how diseases spread, and how stem cells differentiate into more specific cell types.

In the three years between Brett Johnson’s brain cancer surgeries, Brigham and Women's Hospital opened the Advanced Multimodality Image Guided Operating (AMIGO) suite, designed to guide complex treatments and procedures with navigation tools and imaging technologies including MRI, CT (computed tomography), PET (positron emission tomography), fluoroscopy, angiography, and ultrasound.

An important step in planning tumor surgery includes assessing the tumor stiffness to aid in surgical planning. For decades, tumors near the surface of the body have been evaluated for stiffness by simple palpation—the physician pressing on the tissue. Because tumors within the skull cannot be palpated, researchers used Magnetic Resonance Elastography (MRE) to assess pituitary tumor stiffness. MRE reliably identified tumors that were soft enough for removal with a minimally-invasive suction technique versus harder tumors requiring more invasive surgery.

The Institute of Biomedical Imaging and Bioengineering (NIBIB) is delighted to congratulate two of its research grantees, Dr. Michael C. McAlpine and Dr. Craig Duvall, for being named recipients of the prestigious Presidential Early Career Award for Scientists and Engineers (PECASE). The PECASE award is the highest honor bestowed by the United States Government on science and engineering professionals in the early stages of their independent research careers. The award highlights the key role that the Administration places in encouraging and accelerating American technological innovation to grow the economy and tackle the nation’s greatest challenges.

Scientists funded by NIH have developed a new way to identify the state and fate of individual stem cells earlier than previously possible. Stem cells are undifferentiated, serving as building blocks for the various tissues and organs of the body. Understanding a stem cell’s fate—the type of cell it will eventually become—and how far along it is in that process can help scientists better manipulate cells for therapies.

Can your smart watch detect when you are becoming sick? A new study indicates that this is possible. By following 60 people through their everyday lives, researchers found that smart watches and other personal biosensor devices can help flag when people have colds and even signal the onset of complex conditions like Lyme disease and diabetes.
