A new biomaterial can be used to study how and when stem cells sense the mechanics of their surrounding environment. With further development, this biomaterial could be used to control when immature stem cells differentiate into more specialized cells for regenerative and tissue-engineering-based therapies.

Ultrasound imaging is used around the world to help visualize developing babies and diagnose diseases. The next step in ultrasound technology is to image not just anatomy, but specific cells and molecules deeper in the body, such as those associated with tumors or bacteria in our gut. Now scientists say that protein engineering techniques might one day lead to colorful ultrasound images of cells deep within our bodies. Read more at Caltech News.
A new device using shortwave infrared light could greatly improve ear infection diagnoses and drastically reduce unnecessary antibiotic prescriptions, a major cause of antibiotic resistance. Read more at MIT News.
A new study reveals how spontaneous changes in the molecular characteristics of tumors can lead to tumors with a mixed population of cells requiring treatment with several types of therapeutic drugs. Read more at Mass General News.
Fierce Biotech reports on a nanovaccine developed by NIBIB researchers that could enhance a current cancer immunotherapy approach while reducing side effects. Read more at fiercebiotech.com.
During a heart attack, clots or narrowed arteries block blood flow, harming or killing cells in the heart. But damage doesn't end after the crushing pain subsides. Instead, the heart's walls thin out, the organ becomes enlarged, and scar tissue forms. These changes can cause heart failure. Scientists now report they have developed injectable gels to prevent this damage. Read more and watch the video at ACS News.
In a classic experiment, Ivan Pavlov conditioned dogs to salivate at the ringing of a bell. Now, scientists can see what happens in the brains of live animals during this experiment with a new technique. The approach could lead to a greater understanding of how we learn and develop addictions. Read more at ACS News.
