This Week in Science: Fussy Cats, Ghostly Sounds, and Much More!

This week’s science roundup spans practical health findings, pet behavior, spooky physics, and a cosmic lab simulation.

Studies looked at sleep habits and dementia risk, why cats may go off their food, and possible downsides of fish oil supplements.

Researchers also linked allopurinol use to lower heart attack and stroke risk, and explored infrasound as a cause of haunted feelings in old buildings.

In a separate physics advance, Chinese scientists simulated false vacuum decay, a hypothetical quantum process tied to the fate of the Universe.
