Beneath the Antarctic ice, scientists find remnants of a giant river system that flowed for thousands of miles.

Geologists digging into the massive ice sheet of West Antarctica have discovered the remains of an ancient river system that once flowed for nearly a thousand miles.
Perseverance rover recently arrived at Bright Angel, a notable site on Mars distinguished by its light-toned rocks, situated at the edge of the ancient Neretva Vallis river channel.
Last week, NASA ’s Perseverance Mars rover arrived at the long-awaited site of Bright Angel, named for being a light-toned rock that stands out in orbital data. The unique color here, as well as the surface characteristics and location on the edge of the ancient river channel Neretva Vallis, made Bright Angel a location of interest for the Mars 2020 Science Team.

Regional authorities in Brazil on Monday declared a state of emergency as the Pantanal, the world’s largest tropical wetlands, faces “out of control fires,” according to a decree.
The surge of fires before the peak of the dry season has raised alarm for the Pantanal, which extends into Bolivia and Paraguay and is home to a rich array of wildlife, including the world’s highest density of jaguars.
The six-month state of emergency was declared by the state of Mato Grosso do Sul, home to much of the wetlands in Brazil.

BOSTON — There currently is no cure for Parkinson’s disease, but scientists may have discovered a potential path to slow or stop the disease. Parkinson’s disease is a brain disorder that can cause movement problems such as tremors, poor balance, and walking difficulties, and it can also impair cognitive function. There is no cure and treatments aim to simply reduce symptoms. But a new study in mice by researchers at Johns Hopkins offers new hope. They found that the interaction of two proteins is key to the buildup of protein clumps in the brain that damage healthy brain cells in Parkinson’s. They also suggest that disrupting these proteins with a drug already approved by the FDA to treat cancer could potentially slow or stop the brain damage associated with Parkinson’s. The next step would be to conduct clinical trials in humans, but that will take time.
