National Weather Forecast
On Sunday, one system will continue eastward, bringing snow and ice to parts of the Great Lakes and the Northeast, with rain and storms possible from the Mid-Atlantic to the Deep South and Southern Plains. A system in the western United States will bring snow across the Great Basin and the Rockies, with rain in California.
The heaviest snow through early in the week will be in parts of the Rockies, where at least 1-2 feet will be possible. Heavy rain will be possible in the lower Mississippi Valley, where 3”+ of rain could fall.
The Colorado River is overused and shrinking. Inside the crisis transforming the Southwest
More from the Los Angeles Times: “The Colorado River begins as melting snow, trickling from forested peaks and coursing in streams that gather in the meadows and valleys of the Rocky Mountains. Like arteries, its major tributaries take shape across Colorado, Wyoming, Utah and New Mexico, coming together in a great river like no other — a river that travels more than 1,400 miles and has defined the rise of the American Southwest over the last century. Water diverted from the river has enabled agriculture to spread across 5 million acres of farmland and has fed the growth of cities from Denver to Los Angeles, supplying about 40 million people. Harnessing the river’s bounty has provided the foundation for life and the economy across seven states and northern Mexico. But the region has for years depended too heavily on the river, taking more than its flows can support. And in recent years, the river’s water-generating heart in the Rocky Mountains has begun to fail.”
This vending machine’s secret to reducing waste? A hidden dishwasher
More from Fast Company: “This vending machine looks very similar to any other. But when you use it to buy a drink, your beverage comes in a reusable bottle—and when you’re done, it takes the bottle back, sanitizes it, and refills it for someone else. “We think of ourselves as combining a bottling plant with a dishwasher with a soda fountain,” says Manuela Zoninsein, founder and CEO of Kadeya, the Chicago-based startup that designed the machine. “And that’s the first time that’s ever been done.” … The first version of the Kadeya vending machine serves water in glass bottles, though the company will soon begin offering other beverages (it will also pivot to stainless steel bottles, which it says can last indefinitely). Water comes out of one side of the machine when someone scans a QR code, and the empty bottle goes back on the other. Inside, a custom dishwasher cleans and sanitizes the bottle.”
Air pollution is changing how our brain functions, researchers at UBC, UVic find
More from the CBC: “Researchers at the University of British Columbia and University of Victoria have found that exposure to traffic pollution is changing the way our brain works. “Air pollution is affecting our thinking, which could have serious public health effects,” said Chris Carlsten, director of UBC’s Air Pollution Exposure Lab and one of the researchers of the study, published Jan. 14 in the journal Environmental Health. Carlsten says exposure to diesel exhaust for just two hours led to changes in brain function connectivity, a measure of how different regions of the brain interact with each other. The most affected regions are linked to memory and attention, he says. “[Changes in connectivity is] associated with reduced cognitive performance and symptoms of depression, so it’s concerning to see traffic pollution interrupting these same networks,” said Jodie Gawryluk, the study’s first author.”
