This year marks the 90th anniversary of the 1934 Minneapolis Teamsters’ strikes. These strikes changed the course of history and the lives of tens of thousands of working people. They transformed Minneapolis from one of the country’s most notorious anti-union citadels into a “union town” and inspired labor organization from Fargo to Omaha and Duluth to St. Louis. The story of this transformation still resonates with the challenges faced by working women and men in 2024.

Some mammoth bones have been gnawing at North Dakota State Geologist Ed Murphy for more than 35 years.

Murphy on Tuesday described for the North Dakota Industrial Commission how he became aware of a find of mammoth bones in 1988. He updated the commission, which oversees the North Dakota Geological Survey, because his department, in cooperation with the State Historical Society, plans to excavate part of the site and may need to request money from the state to finish the job.

The Minnesota Historical Society is digitizing more a hundred years of Native American newspapers, so they can be accessed online.

“To be able to just archive our histories as it happens, and especially that first-person perspective,” said Rita Walaszek Arndt, program and outreach manager for Native American Initiatives at the Minnesota Historical Society. “Being able to have those primary sources from the people is really important.”

Minneapolis Police Department officers reported using physical force against suspects more than 1,000 times in 2022, one of the highest per-capita rates of police force in the nation, according to data released this week.

MPD officers reported using force at the same rate in 2022 as they did in 2020, the year George Floyd was murdered by MPD officers, led by Derek Chauvin.

Over the same time period, police use of force rose precipitously in neighboring St. Paul, roughly doubling from 2018 to 2022, according to the data. On a per-capita basis, St. Paul police are now more likely to use force against suspects than MPD officers.

This prehistoric carving, discovered inside a cave in France, depicts a steppe wisent (Bison priscus), a now-extinct species of bison. It was crafted from a piece of reindeer antler that was previously used as a spear thrower for hunting, according to the Bradshaw Foundation.

Despite its small size — roughly 4 inches (10.5 centimeters) wide — the figurine contains a wealth of meticulous details, including finely carved individual hairs across the animal's body and a pair of horns jutting from its head, giving the piece a lifelike quality.

The Neolithic farmers and herders who built a massive stone chamber in southern Spain nearly 6,000 years ago possessed a good rudimentary grasp of physics, geometry, geology and architectural principles, finds a detailed study of the site.

Using data from a high-resolution laser scan, as well as unpublished photos and diagrams from earlier excavations, archaeologists pieced together a probable construction process for the monument known as the Dolmen of Menga. Their findings, published on 23 August in Science Advances1, reveal new insights into the structure and its Neolithic builders’ technical abilities.

How did early humans use sharpened rocks to bring down megafauna 13,000 years ago? Did they throw spears tipped with carefully crafted, razor-sharp rocks called Clovis points? Did they surround and jab mammoths and mastodons? Or did they scavenge wounded animals, using Clovis points as a versatile tool to harvest meat and bones for food and supplies?

UC Berkeley archaeologists say the answer might be none of the above.

Instead, researchers say humans may have braced the butt of their pointed spears against the ground and angled the weapon upward in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of on their own.

Minnesota officials certified last week’s primary vote Tuesday, confirming it as the lowest primary turnout since 2016.

Fifteen percent of registered voters cast ballots on Aug. 13. This translates to only 12 percent of all eligible voters. In 2016, 7 percent of eligible people voted.

“The thing about primaries is it is so dependent on who or what is on the ballot. If there's a hot contest somewhere, then people show up. If not, they tend not to,” said Steve Simon, Minnesota’s Secretary of State.

A large-scale study of fossil human teeth from Ice Age Europe shows that climate change significantly influenced the demography of prehistoric humans.

Using the largest dataset of human fossils from Ice Age Europe to date, an international research team shows how prehistoric hunter–gatherers coped with climate change in the period between 47,000 and 7,000 years ago.

Population sizes declined sharply during the coldest period, and in the West, Ice Age Europeans even faced extinction, according to the study published August 16 in the journal Science Advances.

Cooking is important — in fact, some researchers believe it's what allowed our human ancestors to unlock the extra calories needed to grow larger brains. So when was cooking invented?

The timing is uncertain, but evidence suggests people were cooking food at least 50,000 years ago and as early as 2 million years ago. This evidence comes from two fields: archaeology and biology.

One piece of archaeological evidence for cooking is cooked starch grains found in dental calculus, or hardened dental plaque. "People can find it in teeth that are 50,000 years old," said Richard Wrangham, a retired professor of biological anthropology at Harvard University and the author of "Catching Fire: How Cooking Made Us Human" (Basic Books, 2009).

But earlier than that, the evidence is less clear. Generally, scientists look for evidence that people were controlling fire. But evidence of controlled fire isn't necessarily evidence of cooking; — people could have used that fire for heat or to make tools, for example.

Residents gathered Friday to celebrate the closure of Smith Foundry, ending more than 100 years of production and pollution in south Minneapolis’ East Phillips neighborhood.

“Every little ingredient that went into this fight led to this victory,” Joe Vital, an organizer with the East Phillips Neighborhood Institute, told a crowd in Cedar Field Park.

Vital grew up in East Phillips, and was one of the first residents to hear about the federal pollution violations that led to the foundry’s closing. He and dozens of residents gathered, shared food and enjoyed the moment. They screen printed fresh t-shirts with the slogan, “When we fight, we win,” and basked in the rhythm of an Indigenous drum circle.

The group included neighbors who complained about the foundry for years, citing the acrid smell and black dust the building emitted. Their fears were substantiated in May 2023, when the U.S. Environmental Protection Agency conducted a surprise inspection. The EPA found that from 2018 to 2023, the foundry emitted nearly double the amount of pollution allowed by its state-issued permit. The EPA cited the foundry in August 2023 for nine violations of the Clean Air Act.

Michael Rubke, a desk attendant at La Rive condo complex in Minneapolis, is fighting for a union against a behemoth building management company, FirstService Residential of Minnesota, that has a near-monopoly on high-rise condos in the Twin Cities. It’s been a difficult battle so far. The unionization campaign is “at square one,” the 41-year-old explained over the phone after working an overnight shift. “They’re pretending we’re not there.”

But that lack of formal union representation did not stop Rubke and his colleagues throughout the Twin Cities from fighting for—and winning—statewide legislation this summer that improves the terms of their jobs, by beating back a little-known provision used to erode the job security of contracted workers.

Under the legislation, which went into effect on July 1, companies in Minnesota are barred from entering into new contracts that contain restrictive covenants, which function like noncompete agreements but have previously slipped past the prohibitions on noncompetes in Minnesota because they have a slightly different structure. Existing restrictive covenants, however, are left in place.
