Machine-learning system precisely locates neutron-star mergers.
Scientists have long been racking their brains for ways to treat Alzheimer’s disease, the most common type of dementia.
Turns out that the answer may lie within our own brains. Researchers from Northwestern University suggest that enhancing the brain’s immune cells may better equip them to clear out harmful clumps of the toxic protein amyloid beta, a hallmark of Alzheimer’s.
“Our study is highly novel because we had the rare opportunity to analyze one of the largest post-mortem brain cohorts of Alzheimer’s patients treated with amyloid-targeting drugs — similar to those now approved by the FDA for Alzheimer’s disease,” lead author Lynn van Olst said.
The successful landing of a Cedar Park lunar lander is putting the pressure on efforts to build a workforce capable of reaching for the stars.
Interstellar material has been discovered in our solar system, but researchers continue to hunt for where it came from and how it got here. A new study led by Western astrophysicists Cole Gregg and Paul Wiegert recommends Alpha Centauri—the next closest solar system to ours—is a great place to start, highlighting how and why it’s a prime target.
The findings were published March 6 in The Planetary Science Journal.
Interstellar objects are astronomical material, like asteroids or comets, not gravitationally bound to a star. They can come from other solar systems and be thrown into interstellar space by collisions or be slingshotted by a planet or star’s gravity.
To black holes merged and flew away.
A supermassive black hole that doesn’t appear to be where we would expect seems to be travelling at more than a thousand kilometres per second – the result of a giant cosmic collision.

A new understanding of how an observer can change the disorder, or entropy, of a quantum object could help us probe how gravity interacts with the quantum realm.
