The Lead Believers in the paranormal often attribute unsettling sensations in old buildings to spirits, but new research from MacEwan University suggests a more grounded explanation: infrasound. This inaudible sound phenomenon, generated by aging infrastructure like pipes and boilers, may be the physiological trigger behind feelings of dread and irritation, effectively providing the 'bodily discomfort' that fuels ghostly suspicions. The Inaudible Threat: Infrasound and the Boiler Effect The study focuses on infrasound, sound waves that fall below the 20Hz threshold of human hearing. While the human ear cannot detect these frequencies, the body can. Prof. Rodney Schmaltz and his team investigated whether these low-frequency vibrations, commonly found in the basements of old houses, could impact human mood and stress levels. Source Identification: The primary sources of infrasound identified are old pipes, boilers, and ventilation systems. Frequency Range: The waves operate below 20Hz, making them completely inaudible to the human ear. Location: These vibrations are most prevalent in older buildings where infrastructure is aging. Physiological Data: Stress Hormones and Irritability In a controlled experiment involving 36 volunteers, researchers played calming or unsettling music while simultaneously emitting infrasound through hidden subwoofers. The results revealed a distinct physiological shift despite the participants being unaware of the sound's presence. Stress Response: Participants exhibited higher levels of cortisol (the stress hormone) in their saliva. Mood Shift: Volunteers rated the music as sadder and reported feeling more irritated and annoyed. Blindness to Source: Crucially, participants could not identify when the infrasound was active, proving the effect is subconscious. The Psychology of Belief: Priming the Paranormal The research highlights the concept of 'priming,' where a pre-existing belief influences how a person interprets a sensation. For someone already inclined to believe in ghosts, the physical discomfort caused by infrasound provides a tangible explanation for their unease. The Skeptic's View: A non-believer would likely attribute the feeling to a 'stuffy, uncomfortable old building.' The Believer's View: For someone primed to expect a haunting, the same irritation is interpreted as proof of a spirit or presence. Attachment Theory: Infrasound supplies the physical discomfort, allowing a 'ghost or haunting explanation' to attach itself to the experience. Future Outlook and Scientific Validation While the findings are promising, experts like Chris French note that larger studies are required to fully confirm the scope of this effect. While infrasound may explain vague discomfort and 'vague haunting' phenomena, it is unlikely to account for more intense poltergeist activity or visual hallucinations, which require more substantial evidence.

Atlético Madrid have secured a spot in the Champions League semi-finals for the first time in a decade, overcoming a spirited Barcelona side 3-2 on aggregate. The victory was sealed with a crucial goal from Ademola Lookman just seven minutes after Barcelona had levelled the tie.The win marked a significant moment for Diego Simeone's side, who had been waiting 10 years for this achievement.

Despite being down to 10 men for 10 minutes after Eric García was sent off, they continued to push for a goal that would have taken the tie to extra time. However, Ronald Araújo's header in the 96th minute went over the bar, securing Atlético's victory.The win sets up a thrilling semi-final matchup for Atlético, who are eager to return to the final and exorcise the ghosts of past defeats.

The Royal Opera's new production of Britten's 'The Turn of the Screw' begins with an eerie effect: the tenor's voice emerges from absolute blackout, setting the tone for an evasive ghost story that will keep audiences on edge. Director Natalie Abrahami and designer Michael Levine have crafted a staging that masterfully builds tension, using water as a recurring motif to underscore the themes of innocence and corruption.The set design features a traditional country house with doors, beds, and the Governess's haunted desk, while Duncan McLean's videos project images onto an invisible screen, adding to the sense of unease. The ghosts and their silent doppelgangers move through the space, creating skilful misdirections and emphasizing the Governess's desperation.The cast delivers richly woven performances, with Isabelle Peters shining as the intense Governess, Claire Barnett-Jones warm as Mrs Grose, and Elgan Llŷr Thomas persuasive as the volatile Peter Quint. The children, played by Phoenix Matthews and Emilia Blossom Ostroumoff, bring extraordinary detail and presence to their roles.Conductor Bassem Akiki draws a compelling performance from the 13 players in the pit, and the tension only loosens its grip when the cast and production team take their bows. This production of 'The Turn of the Screw' runs at the Linbury theatre, London, until 6 April.
