‘Would you like a little ice with your exoplanet?’ For Earth-like worlds, that may be a tall order
A team at the University of Washington and the University of Bern has computationally simulated more than 200,000 hypothetical Earth-like worlds all in orbit of stars like our sun. As they report in a paper accepted to the Planetary Science Journal and submitted Dec. 6 to the preprint site arXiv, on these simulated exoplanets, one common feature of present-day Earth was often lacking: partial ice coverage. About 90% of these potentially habitable hypothetical worlds lacked partial surface ice like polar caps.
Simulations show how earthquake early warning might be improved for magnitude-9 earthquakes
Seismologists used 30 detailed simulations of magnitude-9 slips on the Cascadia Subduction Zone to evaluate how the ShakeAlert earthquake early warning system would perform in these events. Results show the alerts generally work well, but suggest that lower alert thresholds provide more timely warnings over the full area that will feel the shaking.

Fossil dental exams reveal how tusks first evolved
Many animals have tusks, from elephants to walruses to hyraxes. But one thing tusked animals have in common is that they’re all mammals — no known fish, reptiles or birds have them. But that was not always the case. In a study published Oct. 27 in the Proceedings of the Royal Society B, a team of paleontologists at Harvard University, the Field Museum, the University of Washington and Idaho State University traced the first tusks back to dicynodonts — ancient mammal relatives that lived before the dinosaurs.

Air pollution from wildfires impacts ability to observe birds
Researchers from the University of Washington provide a first look at the probability of observing common birds as air pollution worsens during wildfire seasons. They found that smoke affected the ability to detect more than a third of the bird species studied in Washington state over a four-year period. Sometimes smoke made it harder to observe birds, while other species were actually easier to detect when smoke was present.
