European astronomers have used the Atacama Large Millimeter Array (ALMA) and the James Webb Space Telescope (JWST) to observe a recently discovered giant disk galaxy known as ADF22.1. Results of the new observations, published April 8 on the arXiv preprint server, shed more light on the formation and evolution of this galaxy.

A unique laboratory
ADF22.1, also known as ADF22.A1, is a giant disk barred spiral galaxy residing in a protocluster known as SSA22 at a redshift of 3.09. It has an effective radius of some 22,800 light years and a stellar mass of about 100 billion solar masses...

Picture this: your brain is a high-performance engine. Over decades, it doesn’t just wear down, it also starts to run hot. Tiny “fires” of inflammation smolder deep within the brain’s memory center, creating a persistent brain fog that makes it harder to think, form new memories or even adapt to new environments, all the while increasing the risk to disorders like Alzheimer’s disease.

Scientists call this slow burn “neuroinflammaging,” and for decades it was thought to be the inevitable price of growing older. Until now.

Dark matter may come in two flavors—finally explaining why its signals appear in some galaxies but vanish in others. A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers propose a bold twist: dark matter might not be a single particle at all, but a mix of two different types that must interact with each other to produce detectable signals.

Sometimes, not seeing somet...
