A new study suggests that feelings of haunting or ghostly presence in certain locations may be caused by infrasound, which is sound at frequencies too low for most people to hear. Infrasound can come from things like pipes, fans, or traffic, and it can cause people to feel uneasy or sense something unusual without realizing why.
Key Facts
Infrasound is sound below the range of human hearing but can still affect people subconsciously.
Researchers believe infrasound may explain many reported ghostly sensations and hauntings.
Other environmental factors like magnetic fields, humidity, and lighting also influence these sensations.
Previous studies found people often feel paranormal experiences more strongly in places known to be haunted.
One example involved an engineer who felt ghostly sensations caused by vibrations from an extractor fan.
Infrasound can cause physical feelings such as chills, pressure, or the sense of being watched.
A small study tested infrasound effects by playing it in a haunted house without actors, studying how it affected people’s fear responses.
The research aims to explain paranormal experiences with natural causes rather than supernatural ones.

Taylor Swift has filed trademark applications to protect her voice and image against misuse by artificial intelligence (AI). She applied to trademark two phrases she says and a specific photo of her on stage to prevent unauthorized use of her likeness and voice.
Key Facts
Taylor Swift’s company applied for three trademarks on April 24, 2024.
Two trademarks cover her saying “Hey, it’s Taylor Swift” and “Hey, it’s Taylor.”
The third trademark is for a photo of Swift performing on her Eras Tour, wearing a colorful outfit and holding a pink guitar.
This action aims to stop misuse of her voice and image by AI, like fake AI-generated images and false endorsements.
Actor Matthew McConaughey recently trademarked his famous phrase to prevent similar AI misuse.
Trademark experts say this is a new method to protect voices from AI-generated copies since copyright laws don’t cover AI-created imitations.
Swift already owns over 50 trademarks, including names, song lyrics, and album-related phrases.
Protecting voice and image with trademarks could help artists control how AI uses their likeness in the future.

NASA revealed that two living modules for the Lunar Gateway space station have corrosion problems. The main builder, Northrop Grumman, and the European Space Agency admitted there are issues with the metal parts, and the manufacturer, Thales Alenia Space, is working to fix them by late 2026.
Key Facts
NASA Administrator Jared Isaacman said the Lunar Gateway modules had corrosion during a House hearing.
Northrop Grumman confirmed a manufacturing problem in the habitat module it built.
The European Space Agency also acknowledged corrosion in its habitation module (I-HAB).
Both modules’ pressure vessels were made by Thales Alenia Space, a French-Italian company.
Axiom Space reported similar corrosion problems in its private station module built by Thales.
Thales described the issue as a "well-known metallurgical behavior," likely a polite way to say corrosion.
Thales plans to repair the modules with work finishing by the third quarter of 2026.
NASA stopped the Lunar Gateway project recently, focusing on the Moon’s surface instead.
The corrosion problems could delay the Gateway launch well beyond the original 2024 target.
