Study finds Alaska early warning system offers crucial seconds before strong shaking

For a wide variety of earthquake scenarios in Alaska, an earthquake early warning (EEW) system could provide at least 10 seconds of warning time for hazardous shaking, according to a new report.

Increasing the density and improving the spacing of seismic stations around the state could add 5 to 15 seconds to these estimated warning times, write Alexander Fozkos and Michael West at the University of Alaska Fairbanks. Alaska experiences tens of thousands of earthquakes each year, and has been the site of some of the world’s largest and most destructive seismic events.

The study’s findings, published in the Bulletin of the Seismological Society of America, could help lay the groundwork for the expansion of the U.S. ShakeAlert earthquake early warning system, which now covers California, Oregon and Washington state.

Posting digitally enhanced photos of yourself could have a social cost, researchers find

The use of disclaimer labels on digitally enhanced portraits could have unintended social consequences for their subjects, according to a study by a team of McGill researchers.

Researchers at the Laboratory for Attention and Social Cognition used beauty filters on a common social media application to gradually edit a total of 300 images of 60 women (from 0% to 100%, 25% at a time). They randomly labeled half of the images as “edited” and the other half as “unedited,” regardless of their level of editing.

A sample of 76 then reviewed the images. The participants were asked to rate the individual’s attractiveness, but also to imagine the person’s social life and some of their social qualities.

Study reveals wild chimpanzees learn how to communicate from relatives on mom’s side, not dad’s

Young chimpanzees learn their communication style from their mother and maternal relatives, but show little similarity to the communication behavior of their father and paternal relatives, according to a study published in the open-access journal PLOS Biology by Joseph Mine at the University of Zurich, Switzerland, and colleagues.
