DARPA works to ensure man can trust machine | C4ISRNET

Under initiatives such as the so-called third offset strategy, which on a basic level imagines humans and machines teaming together to overcome the parity competitors have reached with American capabilities, artificial intelligence will be a critical component. For humans, however, learning to trust machines is a real challenge. “A lot of AI today is a black box, you have this ... Read More »

‘Multi-dimensional universe’ in brain networks | ScienceDaily

For most people, it is a stretch of the imagination to understand the world in four dimensions but a new study has discovered structures in the brain with up to eleven dimensions — ground-breaking work that is beginning to reveal the brain’s deepest architectural secrets. Using algebraic topology in a way that it has never been used before in neuroscience, ... Read More »

Vegetarian diets almost twice as effective in reducing body weight, study finds | ScienceDaily

Dieters who go vegetarian not only lose weight more effectively than those on conventional low-calorie diets but also improve their metabolism by reducing muscle fat, a new study published in the Journal of the American College of Nutrition has found. Losing muscle fat improves glucose and lipid metabolism so this finding is particularly important for people with metabolic syndrome and ... Read More »

Diagnostic radiation exposure safe for children, experts state | ScienceDaily

In an article published in the June 2017 issue of The Journal of Nuclear Medicine, researchers assert that exposure to medical imaging radiation not only doesn’t increase an adult person’s risk of getting cancer, it doesn’t increase a child’s risk. According to the authors, the long-held belief that even low doses of radiation, such as those received in diagnostic imaging, ... Read More »
