Researchers found extensive changes in brain cells and genome organization beginning in midlife, with a major transition between roughly ages 50 and 75. Immune cells became more inflammatory, blood-brain barrier support weakened, and the genome's three-dimensional structure deteriorated, offering clues to rising neurodegenerative disease risk.

New World screwworm, a flesh-eating parasite that was eradicated in the United States decades ago, is spreading north and threatening livestock, wildlife, pets and potentially people. Researchers are developing a tracking system to predict its movement as officials rebuild an eradication campaign.
The decisive shift is the parasite’s reentry into U.S. territory, which turns a previously contained

A localized outbreak could become a costly threat to food production, animal health and rural economies.
Summary
Researchers found extensive changes in brain cells and genome organization beginning in midlife, with a major transition between roughly ages 50 and 75. Immune cells became more inflammatory, blood-brain barrier support weakened, and the genome's three-dimensional structure deteriorated, offering clues to rising neurodegenerative disease risk.
The central finding is that brain aging involves a coordinated systems-level transition, not simply gradual

Plant remains from Cloggs Cave indicate that GunaiKurnai ancestors repeatedly carried whole grasses into the cave and burned them in thin layers, possibly as part of ritual practices spanning 25,000 years. A standing stone and other objects support the interpretation of the cave as a long-lived spiritual site.

Observations from the XRISM space telescope indicate that winds from a supermassive black hole carry roughly 100 times more power than previously estimated. The turbulence extends about 300,000 light-years, reaching far beyond the host galaxy and releasing energy comparable to billions of supernovae.
