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

Researchers built a motor that could operate a robotic device made from non-magnetic materials and was powered by the magnetic field produced by the MRI.

In recent years, artificial intelligence (AI) has been recognized as a powerful tool in the field of medical imaging. However, these models can be subject to several biases, leading to inequities in how they benefit both doctors and patients. Understanding these biases and how to mitigate them is the first step towards a fair and trustworthy AI. Source: SPIE

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

NIH-funded researchers developed an online tool that can analyze self-collected, at-home videos with a smartphone. When deployed in a nationwide study, the tool could predict physical health and osteoarthritis of the knee or hip.

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.
