Executive Summary: Unveiling the Source of Coastal Nighttime Rumbles For the first time, researchers have recorded low‑frequency thrums that have haunted Alaskan shorelines for centuries and traced them directly to humpback whales. The discovery expands the known vocal repertoire of these giants and opens new avenues for marine safety and astrobiology. Land‑Based Microphones Capture Unheard Humpback Rumbles Fred Sharpe of the Alaska Whale Foundation and his team deployed shore‑side microphones after receiving tip‑offs from local fishers, lighthouse keepers and kayakers. The recordings revealed familiar whale sounds—trumpets, blows, shrieks—as well as novel low‑frequency rumbles, “pizzle”, howls and hooting noises. Key Metrics from the Field Study Detection range: up to 6 miles (10 km) from the source. Presentation date: 18 May 2026 at the Astrobiology Science Conference in Madison, Wisconsin. Number of new sound types identified: four (rumbles, pizzle, howl, hooting). Implications for Whale Conservation and Maritime Safety The low‑frequency thrums likely originate from specialized structures in the whale’s blowhole that prevent water ingress during dives. Understanding these signals could improve ship‑whale collision avoidance systems and inform acoustic monitoring protocols. Broader Significance for Astrobiology and Signal Detection Sharpe suggests that studying such complex, low‑frequency biosignatures may help refine methods for detecting intelligent life beyond Earth, highlighting a surprising link between marine biology and the search for extraterrestrial intelligence. Future Research Trajectories Ongoing work will map thrum propagation across different coastal topographies, integrate acoustic data with satellite tracking, and explore whether similar vocal mechanisms exist in other cetacean species.

The little corella infestation on Kangaroo Island has reached critical levels, with the birds causing widespread destruction and disruption to daily life. Despite a recent culling effort that resulted in the death of 2,640 little corellas, authorities acknowledge that it won't be enough to mitigate the problem.The birds, which are not native to the island, have been covering a local school in faeces, tearing up infrastructure, damaging crops, and causing mental distress to residents with their screeching. They have also been spotted using the nesting hollows of the endangered glossy-black cockatoo, smashing their eggs and killing their nestlings.Past attempts to control populations by shooting, scaring, trapping, or gassing them have failed, with the highly intelligent birds learning how to survive or just moving to cause havoc somewhere else. The Kangaroo Island Landscape Board's general manager, Will Durack, says that night-time shooting was more efficient, with the roosting birds easier to kill in large numbers, but it is not clear how much of a dent they made in the population.The little corellas have created a perfect environment for themselves on the island, with a predictable water supply from stock troughs and dams, and food from grain crops. Residents have expressed concerns about the physical and mental health impacts of the infestation, including the spread of diseases such as ornithosis and the disruption to daily life caused by the birds' loud shrieks.Coordination with other agencies and more resources are needed if the trial is to be expanded, according to the landscape board. A resident, Rodney Bell, has four grandchildren at the school and says: “They poo all over the yard, then the kids are playing in it.” He also mentions that “near the school, they would drive anyone insane from the sheer noise.”

The Royal Liverpool Philharmonic, led by conductor Daniela Candillari, presented a unique concert experience that juxtaposed the serene with the apocalyptic. The program began with Elgar's Serenade for Strings, a piece that epitomizes Victorian salon music. The performance was gentle and dainty, with a lovely translucent quality to the Allegretto.The highlight of the evening was undoubtedly Mark Simpson's oratorio, 'The Immortal', inspired by Victorian occultism. This 2015 work invites the audience to a seance, featuring texts from mediums of the time and the words of Frederic Myers, founder of the Society for Psychical Research. The piece was characterized by its impossibly dense, deliberately impenetrable textures and apocalyptic soundscapes, complete with amplified howls and shrieks from the vocalists of Exaudi and solo baritone Rory Musgrave.In contrast, the performance of Sibelius's Second Symphony was smooth and polished, but lacked real tension and buildup. The symphony's ominous timpani rumble and scherzo were played with speed, but without the intensity one might expect. Overall, the concert promised life and death but ultimately left the audience hovering in between.
