The glaciers in Montana's Glacier National Park are rapidly disappearing.

Some have been reduced by as much as 85 percent over the past 50 years, while the average loss is 39 percent, according to a new study from the U.S. Geological Survey and Portland State University.

The researchers looked at historic trends for 39 glaciers, 37 of which are found in the park. The other two are on U.S. Forest Service land.

The city of Milwaukee and the family of a black man with schizophrenia who was shot dead by a police officer have reached a tentative $2.3 million settlement agreement, three years after his death.

"Officer Christopher Manney never faced criminal charges, but was fired from the police department for failing to follow protocol," LaToya Dennis of member station WUWM tells our Newscast unit. She adds that the settlement still requires the approval of the Milwaukee Common Council.

In a rare victory for environmentalists under President Trump, the Senate rejected efforts to roll back an Obama-era rule limiting methane emissions from energy production sites on federal land.

The vote over the greenhouse gas was close — 49-51 — with Republican Sens. John McCain, Lindsey Graham and Susan Collins coming down against the resolution, which would have repealed the Bureau of Land Management's Methane Waste and Prevention Rule.

The bones of a humanlike creature have puzzled scientists ever since they were found in a South African cave in 2013.

Homo naledi is primitive in some ways, with a small brain and other physical features reminiscent of our early ancestors. But it also walked upright, and had hands that may have been capable of making tools.

Old rocks found in the Australian Outback have some weighty implications, scientists say: They hint at the environment in which life on Earth originated and suggest a location to search for life on Mars.

Scientists in Australia say they have found biological signatures of life in rocks that also show the presence of a hot spring, lending weight to a theory that the earliest life on Earth might have originated in freshwater hot springs on land rather than in deep-sea hydrothermal vents.
