The National Institute of Biomedical Imaging and Bioengineering has established a new Center for Biomedical Engineering Technology Acceleration, dedicated to applying engineering principles to biomedical discovery and therapeutics. We talk to the Center’s Director Manu Platt about their plans and the focus on diversity, equity, inclusion and accessibility. Source: Nature Reviews Bioengineering

Researchers create a biomimetic model to study wound healing in burn and laceration wounds. The team designed an in vitro model system made of fibroblasts embedded in a collagen hydrogel. Wounds were created in this microtissue using a microdissection knife to mimic laceration or a high-energy laser to simulate a burn. They discovered that fibroblasts clear away damaged tissue before depositing new material. This part of the healing process is slower in burn wounds.

Since the development of functional magnetic resonance imaging in the 1990s, the reliance on neuroimaging has skyrocketed as researchers investigate how fMRI data from the brain at rest, and anatomical brain structure itself, can be used to predict individual traits, such as depression, cognitive decline, and brain disorders. But how reliable brain imaging is for detecting traits has been a subject of wide debate. Researchers now report that stronger links between brain measures and traits can be obtained when state-of-the-art pattern recognition (or 'machine learning') algorithms are utilized, which can garner high-powered results from moderate sample sizes.

Bioengineers from Columbia University are developing a pipeline to systematically evaluate how bacterial treatments might synergize with existing anti-cancer therapies in preclinical models.

Scientists at Duke University supported with funds from NIBIB have developed an ultra-fast photoacoustic imaging system capable of visualizing functional and molecular changes in the brain related to major brain disorders. 

New research found that using focused-ultrasound-mediated liquid biopsy in a mouse model released more tau proteins and another biomarker into the blood than without the intervention. This noninvasive method could facilitate diagnosis of neurodegenerative disorders, the researchers said. Source: Washington University in St. Louis/Science Daily

Doctors at the University of Florida Health Center are using artificial intelligence to help monitor their patients. The findings will help them develop algorithms that will soon provide real-time health care recommendations. NBC News’ Dr. John Torres on the future of technology in healthcare. Source: NBC News

A soldier suffers a serious gunshot wound on a remote battlefield or a machinist has a work accident and gets stuck in traffic on the way to the hospital. Secondary, uncontrolled bleeding from traumatic injury is a leading cause of death for Americans ages one to 46. Chemical and biomedical engineers plan to change that with a novel microneedle patch that can immediately stop bleeding after injury. Source: Penn State/Science Daily

After years of research, an NIH-funded team has developed a wearable cardiac ultrasound imager that can non-invasively capture real-time images of the human heart. The prototype patch, which is about the size of a postage stamp, can be worn during exercise, providing valuable cardiac information when the heart is under stress.
