  • Oceanographers investigate the ocean's carbon-absorbing processes over time
    on June 19, 2019 at 7:46 PM

    It's a well-known fact that the ocean is one of the biggest absorbers of the carbon dioxide emitted by way of human activity. What's less well known is how the ocean's processes for absorbing that carbon change over time, and how they might affect its ability to buffer climate change. […]

  • New platform flips traditional on-demand supply chain approach on its head
    on June 19, 2019 at 7:39 PM

    Imagine you are heading to the grocery store and receive a phone alert asking if you'd also be willing to bring your neighbor's groceries home. Or you are on your way to a concert and see you could fill the seats of your car—and your wallet—if you picked up a few other music fans along the way. As the supplier in these scenarios, you have the choice of which services you provide and when. This may very well be the way commerce is headed. […]

  • Study predicts more long-term sea level rise from Greenland ice
    on June 19, 2019 at 6:00 PM

    Greenland's melting ice sheet could generate more sea level rise than previously thought if greenhouse gas emissions continue to increase and warm the atmosphere at their current rate, according to a new modeling study. The study, which used data from NASA's Operation IceBridge airborne campaign, was published in Science Advances today. In the next 200 years, the ice sheet model shows that melting at the present rate could contribute 19 to 63 inches to global sea level rise, said the team led […]

  • Melting of Himalayan glaciers has doubled in recent years
    on June 19, 2019 at 6:00 PM

    A newly comprehensive study shows that melting of Himalayan glaciers caused by rising temperatures has accelerated dramatically since the start of the 21st century. The analysis, spanning 40 years of satellite observations across India, China, Nepal and Bhutan, indicates that glaciers have been losing the equivalent of more than a vertical foot and half of ice each year since 2000—double the amount of melting that took place from 1975 to 2000. The study is the latest and perhaps most […]

  • Frog protein may mitigate dangers posed by toxic marine microbes

  • Finding 'Nemo's' family tree of anemones
    on June 19, 2019 at 5:18 PM

    Thanks in part to the popular film Finding Nemo, clownfishes are well known to the public and well represented in scientific literature. But the same can't be said for the equally colorful sea anemones—venomous, tentacled animals—that protect clownfishes and that the fish nourish and protect in return. A new study published online this month in the journal Molecular Phylogenetics and Evolution takes a step to change that, presenting a new tree of life for clownfish-hosting sea […]
