Automation uncovers combinations of amino acids that feed two bacterial species and could tell us much more about the 90% of bacteria that humans have hardly studied. An artificial intelligence system enables robots to conduct autonomous scientific experiments -- as many as 10,000 per day -- potentially driving a drastic leap forward in the pace of discovery in areas from medicine to agriculture to environmental science.

Engineers have developed a stretchable ultrasonic array capable of serial, non-invasive, three-dimensional imaging of tissues as deep as four centimeters below the surface of human skin, at a spatial resolution of 0.5 millimeters. This new method provides a non-invasive, longer-term alternative to current methods, with improved penetration depth. Source: University of California - San Diego/Science Daily

The biological age of humans and mice undergoes a rapid increase in response to diverse forms of stress, which is reversed following recovery from stress, according to a new study. These changes occur over relatively short time periods of days or months, according to multiple independent epigenetic aging clocks. Source: Cell Press/Science Daily

Developing and testing new treatments or vaccines for humans almost always requires animal trials, but these experiments can sometimes take years to complete and can raise ethical concerns about the animals' treatment. Now, researchers reporting in ACS Central Science have developed a new testing platform that encapsulates B cells -- some of the most important components of the immune system -- into miniature 'organoids' to make vaccine screening quicker and greatly reduce the number of animals needed.

Missing crucial doses of medicines and vaccines could become a thing of the past thanks to Rice University bioengineers' next-level technology for making time-released drugs. Source: Rice University/Science Daily

Scientists have employed inventive chemistry to produce an injectable biomaterial with significantly improved adhesive strength, stretchability, and toughness. This chemically modified, gelatin-based hydrogel has attractive features, including rapid gelation at room temperature and tunable levels of adhesion. This custom-engineered biomaterial is ideal as a surgical wound sealant, with its controllable adhesion and injectability and its superior adherence to a variety of tissue and organ surfaces.

When lymphatic vessels fail, typically their ability to pump out the fluid is compromised. Researchers have now developed a new treatment using nanoparticles that can repair lymphatic vessel pumping. Traditionally, researchers in the field have tried to regrow lymphatic vessels, but repairing the pumping action is a unique approach. Source: Georgia Institute of Technology/Science Daily

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
