        Scientists develop new, faster method for seeking out dark matter

        Boulder CO (SPX) Feb 11, 2021
        For nearly a century, scientists have worked to unravel the mystery of dark matter - an elusive substance that spreads through the universe and likely makes up much of its mass, but has so far proven impossible to detect in experiments. Now, a team of researchers have used an innovative technique called "quantum squeezing" to dramatically speed up the search for one candidate for dark matter in the lab. The findings, published in the journal Nature, center on an incredibly lightweight and as-of-ye ... read more

        Harnessing the power of AI to understand warm dense matter

        Dresden, Germany (SPX) Jan 29, 2021
        The study of warm dense matter helps us understand what is going on inside giant planets, brown dwarfs, and neutron stars. However, this state of matter, which exhibits properties of both solids and plasmas, does not occur naturally on Earth. It can be produced artificially in the lab using large X-ray experiments, albeit only at a small scale and for short periods of time. Theoretical and numerical models are essential to evaluate these experiments, which are impossible to interpret without formu ... read more
