MIT computer scientists have developed a system that learns to identify objects within an image, based on a spoken description of the image. Given an image and an audio caption, the model will highlight in real-time the relevant regions of the image being described.

For the first time ever, an international research group detected alterations in capillary blood flow around the face caused by body position change. This became possible through the use of imaging photoplethysmography. Using this method, scientists can examine blood vessels located in the carotid system in order to, for example, investigate the cerebral blood flow response to various stimuli in health and disease. The results of the research were published in Scientific Reports.

Variations in power generation using renewable sources lead to control problems in the electricity grid. The technology of lithium batteries is a candidate offering great potential in solving these problems. An industrial engineer at the Public University of Navarre (NUP/UPNA) has developed a new management system that allows good performance of these batteries to be achieved and their lifetime to be preserved when connected to a renewable facility to store the electrical energy produced.

A mobile app that guides pedestrians along the safest instead of quickest route to their destination is being developed by researchers at Cardiff University.

Artificial intelligence (AI) can be an invaluable aid to help lung doctors interpret respiratory symptoms accurately and make a correct diagnosis, according to new research presented at the European Respiratory Society International Congress.

Covert sensing of objects around a corner may soon become a reality. Aristide Dogariu, a University of Central Florida Pegasus Professor of Optics and Photonics, and his colleagues published a paper in Nature Communications this month demonstrating how to passively sense an object even when direct vision is impeded.
