In Alaska, soil in permafrost regions is warming the fastest (opens the original)
Read excerpt
PULLMAN, Wash. — Soils are warming quickly and at considerable depth across Alaska, with temperatures rising fastest in the state’s permafrost region, a trend that could accelerate climate change and undermine the stability of roads, buildings and other infrastructure built on the continuously frozen ground. That’s a central finding of new research from Washington State University that provides a comprehensive look at soil temperatures from 1997 to 2023 in a state where the effects of climate ch
AI can help correct medical misinformation — when it uses the right tone (opens the original)
Read excerpt
PULLMAN, Wash. — At a time of rampant medical misinformation online, artificial intelligence can do a good job of correcting falsehoods, but the tone of the correction is key, according to new research led by Washington State University. For people who view AI strictly as a technical tool, corrections to social media posts offered in a neutral, just-the-facts tone are most persuasive. For those who believe AI can be humanlike, an empathetic, understanding tone is best. In fact, according to the
Think cannabis reduces stress? New study finds it’s complicated (opens the original)
Read excerpt
PULLMAN, Wash. — Cannabis is often used as a stress reliever, but a new study suggests that some of the body’s stress response systems don’t get the message. A human trial of regular cannabis users found that cannabis use lowered some physiological stress measures, such as cortisol levels, but others remained unaffected or increased after vaping cannabis. Notably, cannabis use corresponded with a faster heart rate and had no effect on heart rate variability, a key measure of stress response. The
Study maps where humans are driving harmful nutrient levels along coasts (opens the original)
Read excerpt
VANCOUVER, Wash. — Along a quarter of the planet’s coastal waterways, humans contribute more harmful nitrogen – via agricultural runoff, wastewater discharges and other activities – than all natural sources combined. That is a key finding from a new study, led by Washington State University, that measured and mapped the human impact on nitrogen, phosphorus and silicon inputs to the planet’s coastal waters, which can have a destructive impact on marine life, as well as health risks for people. “C
Robinhood users target simplicity in choosing stocks (opens the original)
Read excerpt
PULLMAN, Wash. — Millions of investors using the Robinhood app tend to favor simpler, easy-to-understand stocks, according to new research from Washington State University — and those stocks outperformed more complex firms during the study period. Those are among the findings of a new paper that examined investment patterns on Robinhood, the popular commission-free, game-like app and web platform. Some 28 million people use Robinhood, with an average user age of 35, according to the company. Und
