Machine learning unearths signature of slow-slip quake origins in seismic data
Combing through historical seismic data, researchers using a machine learning model have unearthed distinct statistical features marking the formative stage of slow-slip ruptures in the earth’s crust months before tremor or GPS data detected a slip in the tectonic plates. Given the similarity between slow-slip events and classic earthquakes, these distinct signatures may help geophysicists understand the timing of the devastating faster quakes as well.

Cool New Worlds Found in Our Cosmic Backyard
How complete is our census of the Sun’s closest neighbors? Astronomers using NSF’s NOIRLab facilities and a team of data-sleuthing volunteers participating in Backyard Worlds: Planet 9, a citizen science project, have discovered roughly 100 cool worlds near the Sun — objects more massive than planets but lighter than stars, known as brown dwarfs. Several of these newly discovered worlds are among the very coolest known, with a few approaching the temperature of Earth — cool enough to harbor water clouds.
Surprising Coral Spawning Features Revealed
When stony corals have their renowned mass spawning events, in sync with the moon’s cycle, colonies simultaneously release an underwater “cloud” of sperm and eggs for fertilization. But how do the sperm and eggs survive several hours as plankton, given threats from predators, microbes and stresses such as warming waters? A Rutgers-led team has discovered some surprising features in coral sperm and eggs (collectively called gametes), according to a study in the journal PeerJ.
Cold-weather accounts for almost all temperature-related deaths

Low-Cost Home Air Quality Monitors Prove Useful for Wildfire Smoke
Published recently in the journal Sensors, a new study by Berkeley Lab air quality scientists tested four models of low-cost air quality monitors during actual wildfire pollution events and found that their readings of PM2.5 – or particulate matter under 2.5 microns, which has been linked to respiratory and cardiovascular issues – were consistently higher than the reference monitor used by the regulatory agencies; however, since each monitor had a relatively consistent response to the smoke, it is possible to use the readings to estimate true PM2.5 levels. Overall, the researchers concluded that the monitors can provide actionable information.

For nearly 50 years, a statistical omission tantamount to data falsification sat undiscovered in a critical study at the heart of regulating one of the most controversial and widely used pesticides in America — chlorpyrifos.
Airing commercials after political ads actually helps sell nonpolitical products
About $7 billion reportedly will be spent this fall on television and digital commercials from political campaigns and political action committees, filling the airwaves with political ads many viewers dislike. Companies running ads immediately afterward have been concerned about the potential of a negative spillover effect on how they and their products and services are perceived. But new research from the Indiana University Kelley School of Business finds that the opposite is true. Contrary to mainstream thought, political ads instead yield positive spillover effects for nonpolitical advertisers.
