A team at the ÌìÃÀÓ°ÊÓ´«Ã½ 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.

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.

Underwater microphones show that killer whales, or orcas, have spent more time in the Arctic Ocean in recent years. The increasingly ice-free Arctic Ocean may give orcas more opportunity to hunt for prey off the west and north coasts of Alaska.

Children as young as age 6 develop stereotypes that girls aren’t interested in computer science and engineering, according to new research from the ÌìÃÀÓ°ÊÓ´«Ã½ and the University of Houston.

Results show that by the end of this century, lower-oxygen water on the Pacific Northwest coast will pose the biggest threat to Dungeness crabs. And while these crabs start as tiny, free-floating larvae, it’s the sharp-clawed adults that will be most vulnerable.

In a rare stroke of luck, researchers from the ÌìÃÀÓ°ÊÓ´«Ã½, the University of California, Berkeley, and the University of California, Santa Barbara, were able to track a group of black-tailed deer during and after California’s third-largest wildfire, the 2018 Mendocino Complex Fire. The megafire, which torched more than 450,000 acres in northern California, burned across half of an established study site, making it possible to record the movements and feeding patterns of deer before, during and after the fire.

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 ÌìÃÀÓ°ÊÓ´«Ã½ and Idaho State University traced the first tusks back to dicynodonts — ancient mammal relatives that lived before the dinosaurs.

Firefighters have reported that Western wildfires are starting earlier in the morning and dying down later at night, hampering their ability to recover and regroup before the next day’s flareup. A study by ÌìÃÀÓ°ÊÓ´«Ã½ and U.S. Forest Service scientists shows why: The drying power of nighttime air over much of the Western U.S. has increased dramatically in the past 40 years.

Astronomers have long suspected that superflares, extreme radiation bursts from stars, can cause lasting damage to the atmospheres — and thus habitability — of exoplanets. A new study published in the Monthly Notices of the Royal Astronomical Society reports that they pose only a limited danger to planetary systems.

Seeing the urgent need for change, a team of scientists from leading research universities, conservation organizations and government laboratories across the West has produced a synthesis of the scientific literature that clearly lays out the established science and strength of evidence on climate change, wildfire and forest management for seasonally dry forests. The goal is to give land managers and others across the West access to a unified resource that summarizes the best-available science so they can make decisions about how to manage their landscapes.

A study published June 16 in Biotropica by a team of researchers at the ÌìÃÀÓ°ÊÓ´«Ã½, the UW Burke Museum of Natural History and Culture, WWF Hong Kong and the University of Colombo has provided an important road map to conserving rough-nosed horned lizards in Sri Lanka.

Climate change is further exacerbating human-wildlife conflicts by straining ecosystems and altering behaviors, both of which can deepen the contacts — and potential competition — between people and animals. In an article published July 30 in the journal Science, Briana Abrahms, an assistant professor of biology at the ÌìÃÀÓ°ÊÓ´«Ã½ and its Center for Ecosystem Sentinels, calls for expanding research into the many ways that climate change will impact the complex interplay between human activities and wildlife populations.
