    White noise. Dark fear.

    White noise is not the same as other noise – and even a quiet environment does not have the same effect as white noise. With a background of continuous white noise, hearing pure sounds becomes even more precise, as researchers have shown. Their findings could be applied to the further development of cochlear implants.

    Abstract thoughts…

    Researchers at Carnegie Mellon University have leveraged machine learning to interpret human brain scans, allowing the team to uncover the regions of the brain behind how abstract concepts, like justice, ethics and consciousness, form. In this study, Just and his team scanned the brains of nine participants using a functional MRI. The team sifted through […]

    Old mathematics… Broken cosmos… Blurry image…

    By combining cutting-edge machine learning with 19th-century mathematics, a Worcester Polytechnic Institute (WPI) mathematician worked to make NASA spacecraft lighter and more damage tolerant by developing methods to detect imperfections in carbon nanomaterials used to make composite rocket fuel tanks and other spacecraft structures. Using machine learning, neural networks, and an old mathematical equation, Randy […]

    Hallucinations…

    Hallucinations are spooky and, fortunately, fairly rare. But, a new study suggests, the real question isn’t so much why some people occasionally experience them. It’s why all of us aren’t hallucinating all the time. In the study, Stanford University School of Medicine neuroscientists stimulated nerve cells in the visual cortex of mice to induce an […]

    Passing through walls… Broken glass…

    Researchers have captured the most direct evidence to date of Klein tunneling, a quantum quirk that allows particles to tunnel through a barrier like it’s not even there. The result may enable engineers to design more uniform components for future quantum computers, quantum sensors and other devices. (1) We constantly see things. We sense things. […]
