    Smartly dressed: Researchers develop clothes that sense movement via touch

    Measuring a person's movements and poses, smart clothes could be used for athletic training, rehabilitation, or health-monitoring.

    In recent years there have been exciting breakthroughs in wearable technologies, like smartwatches that can monitor your breathing and blood oxygen levels.

    ​Why the simulation hypothesis is pseudoscience

    The simulation hypothesis is fun to talk about, but believing it requires an act of faith.

    • The simulation hypothesis posits that everything we experience was coded by an intelligent being, and we are part of that computer code.
    • But we cannot accurately reproduce natural laws with computer simulations.
    • Faith is fine, but science requires evidence and logic.

    'Deep Nostalgia' AI brings old photos to life through animation

    Using machine-learning technology, the genealogy company My Heritage enables users to animate static images of their relatives.

    • Deep Nostalgia uses machine learning to animate static images.
    • The AI can animate images by "looking" at a single facial image, and the animations include movements such as blinking, smiling and head tilting.
    • As deepfake technology becomes increasingly sophisticated, some are concerned about how bad actors might abuse the technology to manipulate the pubic.

    ​These light-emitting "smart" tattoos could act as medical monitors

    Light-emitting tattoos could indicate dehydration in athletes or health conditions in hospital patients.

    • Researchers at UCL and IIT have created a temporary tattoo that contains the same OLED technology that is used in TVs and smartphones.
    • This technology has already been successfully applied to various materials including glass, food items, plastic, and paper packaging.
    • This advance in technology isn't just about aesthetics. "In healthcare, they could emit light when there is a change in a patient's condition - or, if the tattoo was turned the other way into the skin, they could potentially be combined with light-sensitive therapies to target cancer cells, for instance," explains senior author Franco Cacialli of UCL.
