A swelling population of feral "super pigs" in Canada is threatening to spread across the border into northern U.S. states, wildlife experts warn.
Threat level: States including Minnesota and Montana are taking preventative measures in case this crossbreed of wild boar and domestic swine that University of Saskatchewanprofessor Ryan Brook calls "the most invasive animal on the planet" crosses the border, per AP.
A series of storms threatening a large portion of the U.S. this week were "likely" to cause holiday travel disruptions for some of the 54.4 million people preparing for Thanksgiving trips, forecasters warned.
The big picture: The severe weather that began on Monday and saw a storm system moving from the southern Plains to the Northeast U.S. through Wednesday was easing, though the National Weather service noted "snow, wind, and icy roads will impact traffic in Utah, Southern Wyoming, Colorado and the Nebraska Panhandle on Thanksgiving."
Scientists researching what causes an itch in skin conditions such as eczema and dermatitis have made a major breakthrough.
Why it matters: The research that has for the first time shown that bacteria can cause itch by activating nerve cells in the skin could help with treating itches that occur in inflammatory skin conditions, per Harvard Medical School scientists whose study was published in the journal Cellon Wednesday.
