Phys.org / Elephant declines could trigger wider ecosystem losses in African savannas, 15-year test shows

For decades, ecologists have theorized that the extinction of one important species could set off a chain reaction of losses throughout an ecosystem. Now, new research offers some of the clearest real-world evidence that ...

Phys.org / Webb reveals black hole that formed before its galaxy

Which comes first, the galaxy or the black hole? We don't know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can ...

Phys.org / Chromosome model links one steady motor to shape shift needed for cell division

It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half. Rice University professor ...

Phys.org / Modeling the Gulf: A researcher's quest to map every current, particle and tide

Understanding the dynamics of how water moves is deceptively simple in concept and endlessly complex in practice. Real-world marine environments are anything but controlled: weather, seasons, and geography change constantly. ...

Medical Xpress / Brain waste maps reveal 'nearest exit' routes and hidden Alzheimer's breakdown

Think of the brain as if it were a house. Insulated from its environment, a house relies on complex networks—pipes, drains, and disposal systems—that interface with the outside world to keep the home functional on the inside. ...
