by Kathryn Willis, Britta Denise Hardesty, Katie Conlon, Win Cowger, The Conversation Credit: Unsplash/CC0 Public Domain In the two decades to 2019, global plastic production doubled. By 2040, plastic manufacturing and processing could consume as much as 20% of global oil production and use up 15% of the annual carbon emissions budget. Most of the …
Credit: Pixabay/CC0 Public Domain Over the last 25 years, the ozone hole which forming over Antarctica each spring has started to shrink. But over the last four years, even as the hole has shrunk it has persisted for an unusually long time. Our new research found that instead of closing up during November it has …
Credit: Unsplash/CC0 Public Domain I first encountered the three-body problem 60 years ago, in a short story called “Placet is a Crazy Place” by American science fiction writer Frederic Brown. In Brown’s story, Placet is a planet in a figure-of-eight orbit around two stars, one of which is composed of ordinary matter, the other of …
Beyond DESI, a slew of new instruments are coming online in the coming years, including the 8.4-meter Vera Rubin Observatory in Chile, NASA’s Nancy Grace Roman Space Telescope, and the European Space Agency’s Euclid mission. “Our data in cosmology has made enormous leaps over the last 25 years, and it’s about to make bigger leaps,” …

Credit: Spotted Towhee (U.S. Fish and Wildlife Service photo, George Gentry) PSW ecologist and tribal liaison Frank Lake wondered how the birds he grew up with in northeastern California were faring. As a Karuk tribal descendant with Yurok family, Lake has a deep connection to …
On the left, six representative amorphous carbons obtained from the large-scale MD simulations are plotted and obvious topological differences can be identified clearly. On the right, the discontinuous phase diagram of amorphous carbons is shown, in which the dashed lines and together with the index ‘n’ give the fitted power law, log(sp3/sp2) ~ ρn, for …
Fig. 1 The transport results of FeSe/δ-doped SrTiO3(001), in comparison with FeSe/SrTiO3(001). Credit: Science China Press Interface engineering has been proven to be effective in discovering new quantum states, such as topological states, superconductivity, charge density waves, magnetism, etc., which require atomic-scale heterostructure fabrication. Monolayer FeSe on SrTiO3 substrates has attracted intense interest owing to …
Researchers studied landslides around the world, like the 2008 disaster in Beichuan, China, to develop a new paradigm for understanding their movements and failure types. Credit: Kushanav Bhuyan Landslides are one of the most destructive natural disasters on the planet, causing billions of dollars of damage and devastating loss of life every year. By introducing …
Illustration of some of the marine food items described in the scientific paper as umami-rich blue food. Credit: Jonas Drotner Mouritsen Greening the way we eat needn’t mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to “boring” vegetables. University of Copenhagen gastrophysicist Ole G. Mouritsen …
