What’s the fishing limit on neutrinos these days?

Your daily Minnesota news roundup starts … NOW. The tradeoffs of technology for parents are legion. When they’re very young, you have to weigh the cognitive and social perils of handing them a screen against getting a tantrum-free meal every once in a while. As soon as you get them a phone, there can be endless struggles about access and screentime and social media . But you can also track their location, a real godsend to parents who want to afford their children a measure of freedom in their activities . And this doesn’t stop when they leave the house, apparently . Parents of children who have become young adults still often track their location , and those parents are probably also tracking the location of their parents to make sure they’re alright. As ever, it comes down to having open lines of communication and trust . Of all the things one can find in Lake Superior — walleye, loons, the wreck of the Edmund Fitzgerald, lake trout, Isle Royale — I bet you wouldn’t think one of the things people are looking for are “ghost particles.” But this week a 238-foot vessel called the Neil Armstrong sailed into Lake Superior on that exact mission, hoping to find neutrinos 200 meters below the surface. “What we’re doing here at the bottom of Lake Superior is nothing less than the exploration of the cosmos,” said Rob Munier, Vice President for Marine Facilities and Operations at the Woods Hole Oceanographic Institution, “to help answer the question: Why do we live in a matter-dominated universe? Or put more simply, why are we here?” The average age of the population is going up as Boomers get older and birth rates decline , but even as demand for nursing home facilities goes up, the quality of those nursing homes is declining in Minnesota. The number of nursing homes has dropped from 376 in 2019 to 340 today, but the number receiving the lowest rating from the federal government has gone from 34 to 64 in that same time span. One of the major issues? The shift from nonprofit models to for-profit models.

Penny: A visitor paying their respects. Nickel: The visitor and the service member trained together, such as at boot camp. Dime: The visitor and the service member served together, such as on deployment. Quarter: The visitor was there when the service member died, possibly in action. At Fort Snelling, leaving the coins on the graves can cause issues including discoloration and problems for lawn mowers , so the coins are collected occasionally and contributed to the cemetery’s beautification fund.

If you’re in a band, the TL;DR is: send them actual emails not text messages . Related
