(via sciencedaily.com) Original source Artificial Intelligence (AI) and 3D images of the human tongue have revealed that the surface of our tongues are unique to each of us, new findings suggest. The results offer an unprecedented insight into the biological make-up of our tongue's surface and how our sense of taste and touch differ from person to person.
Published Cognitive strategies for augmenting the body with a wearable, robotic arm
(via sciencedaily.com) Original source Scientists show that breathing may be used to control a wearable extra robotic arm in healthy individuals, without hindering control of other parts of the body.
Published Nanoprobe with a barcode
(via sciencedaily.com) Original source Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, making it important to have methods that can selectively detect active proteases. Scientists have introduced a new class of protease-activity sensors: gold nanoparticles equipped with peptide DNA.
Published Can AI be too good to use?
(via sciencedaily.com) Original source Much of the discussion around implementing artificial intelligence systems focuses on whether an AI application is 'trustworthy': Does it produce useful, reliable results, free of bias, while ensuring data privacy?
