The damage of strokes caused by brain bleeds can be mitigated by removing dead blood cells. Scientists have now found a way of doing this non-invasively, with promising results in mice

Models help scientists understand everything from the particles that make up the universe to massive superstructures of galaxies at the beginning of time. But sometimes they model more mundane, though perhaps even more complex, features - including the course of human civilization. A new paper by Thomas Leppard of the International Archaeological Research Institute and his co-authors, all of whom are also archeologists, propose applying a model of how humans expanded to the different islands across the Pacific Ocean during their early migration to what glean insights into how humanity should manage our colonization of space.

In a new book, NASA astrobiologist Caleb Scharf says the fate of life on Earth may hinge on leaving our planet behind

There is growing evidence that our reliance on generative AI tools is reducing our ability to think clearly and critically, but it doesn’t have to be that way

Space dust provides more than just awe-inspiring pictures like the Pillars of Creation. It can provide the necessary materials to build everything from planets to asteroids. But what it actually looks like, especially in terms of its “porosity” (i.e. how many holes it has) has been an area of debate for astrochemists for decades. A new paper from Alexey Potapov of Friedrich Schiller University Jena and his co-authors suggest that the dust that makes up so much of the universe might be “spongier” than originally thought.

Back in 2009, astronomers using the Fermi Gamma-ray Space Telescope noticed that there was a lot more gamma-ray light coming from the center of the Milky Way than might otherwise be expected given the objects there. Since then, two theories have appeared to explain this Galactic Center Excess (GCE) as it’s become known. One theory posits that the extra gamma rays are created by thousands of unseen milli-second pulsars (MSPs) in the Galactic center, while the other suggests that dark matter annihilating itself could also be the source. A new paper from Moortis Muru and hisco-authors at the Leibniz Institute for Astrophysics Potsdam (AIP) hasn’t necessarily solved the conundrum, but does level the playing field between the two theories again.
