Engineers have developed a bio-compatible ink that solidifies into different 3D shapes and structures by absorbing ultrasound waves. Because the material responds to sound waves rather than light, the ink can be used in deep tissues for biomedical purposes ranging from bone healing to heart valve repair.

An intense international effort to improve the resolution of magnetic resonance imaging (MRI) for studying the human brain has led to an ultra-high resolution 7 Tesla scanner. It records up to 10 times more detail than current 7T scanners and over 50 times more detail than current 3T scanners, which most hospitals use.Be
A new wearable brain scanner is the first of its kind to accurately record magnetic fields generated by brain activity while people are in motion, a new research paper reports. This advance will enable researchers to learn more about brain development and neurological conditions that can affect movement, including autism, epilepsy, stroke, concussion, and Parkinson's disease.
By combining non-invasive imaging techniques, a team of investigators led by Massachusetts General have created a comprehensive cellular atlas of a region of the human brain known as Broca’s area. The methods could be used to create 3D models of particular brain areas and the entire human brain. Source: Massachusetts General Hospital/Science Daily
Researchers have long recognized the therapeutic potential of using magnetoelectrics ⎯ materials that can turn magnetic fields into electric fields ⎯ to stimulate neural tissue in a minimally invasive way and help treat neurological disorders or nerve damage. A Rice University led team have designed the first magnetoelectric material that can be used to precisely stimulate neurons remotely and to bridge the gap in a broken sciatic nerve in a rat model.

Researchers at Ohio State University have developed nanocarriers derived from mice skin cells that reduced lung inflammation in mice. Further research could lead to a treatment for acute respiratory distress syndrome and other conditions.
An NIBIB-funded research education program designed to diversify the biomedical workforce inspired two participants to pursue Ph.D. research in biomedical engineering.
Traditional medical imaging works great for people with light skin but has trouble getting clear pictures from patients with darker skin. A Johns Hopkins University–led team found a way to deliver clear pictures of anyone's internal anatomy, no matter their skin tone. Source: Johns Hopkins University
Some people using antigen tests have experienced a negative test result only to find out that they have the virus. New research shows that repeat testing every other day increases the detection of the SARS-CoV-2 virus.
