But new modeling published yesterday in the Proceedings of the National Academy of Sciences shows that 84 percent of airborne microplastics in the American West actually comes from the roads outside of major cities.
“The 2020 heat wave in the Russian Arctic shows how—even at high latitudes—really warm weather conditions can develop that can lead to fires that burn intensely and can grow to be very large,” says Isla Myers-Smith, an ecologist at the University of Edinburgh who studies the region but wasn’t involved in this new work.
Climate change is making the urban heat-island effect all the more dire in cities across the world, and it’s only going to get worse.
“And that's not really good when you're trying to hear animals that are many miles away making sounds.” So Baumgartner and his colleagues made the first 100 feet of mooring out of a rubbery “stretch hose.” When the buoy bobs on waves and tugs on the mooring, that stretchy bit coming off the instrument stays silent, allowing the hydrophone to listen for whales undisturbed.
He requires only a camera, model cars, and a bit of Photoshop to send muscle cars flying in his new book, The Heights . In the final images, the muscle cars careen above the streets so high they look like they're taking off—or coming in for an impossible landing.
On the bright side, that means a smaller cottage industry will be needed to ensure that Drogon is fed and cared for without laying waste to the rest of Westeros—or so determined a trio of Maryland high school students on their way to outdueling thousands of other teams in the prestigious Mathematical Contest in Modeling (MCM).
Not only does the study not necessarily serve as the basis of any kind of reliable truth-telling algorithm, but it makes potentially dangerous claims: A text-based "online polygraph" that's faulty, they warn, could have far worse social and ethical implications if adopted than leaving those determinations up to human judgment.
(The software they used treats the latent space somewhat differently from the way a generative adversarial network treats it, so it is not technically a GAN, though similar.) Their model created artificial data sets as a way of testing hypotheses about physical processes.
“Energy-intensive forms of cultured production could be quite an extreme case, where you're basically swapping methane—because cattle emit a lot of methane—for potentially fossil fuel carbon dioxide,” says study lead author John Lynch, an environmental scientist at the University of Oxford.
Every morning, Lena Forsen wakes up beneath a brass-trimmed wooden mantel clock dedicated to “The First Lady of the Internet.” It was presented to her more than two decades ago by the Society for Imaging Science and Technology, in recognition of the pivotal—and altogether unexpected—role she played in shaping the digital world as we know it.
Thus the fire sucks in surface winds.Researchers are using supercomputers and lookout stations like this to model the dynamics of wildfires in real time. At Los Alamos National Laboratory, atmospheric scientist Alexandra Jonko is using a supercomputer and a system called FIRETEC to model fires in extreme detail.
The megafires paper is one of two recently released studies based on data from NASA’s Arctic Boreal Vulnerability Experiment, or ABoVE, that will help scientists better understand and predict both short- and long-term changes in the ecosystems of Alaska and Northern Canada.
