    Climate change will make Atlantic tropical storms worse

    "Atlantic hurricane seasons will become even more active in the future, and hurricanes will be even more intense."

    climate change

    Gulf of Maine cooled for 900 years then started warming

    Clam shells and climate simulations show that the Gulf of Maine suddenly started warming after 900 years of gradual cooling.
  • A yellow, rusting sign reads "Caution: High pressure gas pipeline"
    climate change

    Catalyst turns methane into chemicals for making plastic

    A new catalyst technology could advance efforts to keep methane, which produces more warming than other greenhouse gases, out of the atmosphere.

    It would pay to link eastern and western power grids

    Two new papers offer evidence that linking the two giant power grids in the US would offer benefits.

    Tech gets metal to mimic natural rose petal powers

    A new technology lets researchers use metal to create nature-inspired surfaces with unique powers, including rose petals' water-repelling ability.

    Thin tissue flutter can damage replacement heart valves

    Thinner tissues in replacement heart valves can create a problematic and even damaging flutter, new research shows.

    brains

    TBI damage may come from tiny bubble bursts

    The formation and collapse of microbubbles in spinal fluid may be to blame for some of the damage of traumatic brain injuries, researchers report.
  • A neon sign in the shape of a fish has "Fresh" in red neon letters on it
    food

    Wildly thin histamine sensors spot fish gone foul

    "This histamine sensor is not only for fish. Bacteria in food produce histamine. So it can be a good indicator of the shelf life of food."

    Next gen solar cells can handle 390-degree heat

    "Our perovskite solar cells show no thermal degradation even at 200 degrees Celsius (390 degrees Fahrenheit) for over three days..."

    Giant ice machine leads to glacier ‘slip law’

    The huge machine keeps ice at the right temperature to examine how melting glaciers slide. It led to a new "slip law" to benefit future research.

    Aussie rocks show early Earth was a ‘water world’

    Early Earth 3.2 billion years ago was a world of vast oceans and submerged continents. The new findings could have implications for the origins of life.

    Vanishing oils in fingerprints can reveal their age

    The degradation of unsaturated oils due to reaction with ozone in the air can provide the age of fingerprints. It could tie suspects to crime scene.
