A highly complete Tyrannosaurus rex fossil named Gus is expected to sell for more than $30m at a Sotheby’s auction, intensifying concerns among scientists that soaring prices are pushing museums out of the market for important specimens. Researchers warn that private ownership prevents long-term scientific study and public access, while auctioneers argue that fossil hunters deserve compensation for the extensive work and risks involved in excavations. The debate highlights tensions between commercial fossil sales, scientific needs, and preservation as wealthy collectors increasingly dominate high‑value auctions.

A highly complete Tyrannosaurus rex fossil named Gus is expected to sell for more than 30 million dollars at a Sotheby’s auction, intensifying concerns among scientists that rising prices are pushing important specimens out of museum reach. Experts warn that private ownership limits scientific study, as leading journals reject research based on privately held fossils. Auctioneers argue that high valuations reflect the immense effort and risk involved in excavation. Despite differing perspectives, collectors, scientists and auction houses agree that fossil hunters play a crucial role in preserving specimens that might otherwise erode or be lost forever.

Experts explain when to open or close windows, where to place and aim electric fans, and how to enhance cooling during hot weather. They recommend keeping windows shut during the day, directing fans broadly at the body to improve sweating efficiency, and using ice or water to aid evaporation. Misting devices can help if used moderately, while covering fans with wet towels is unsafe. Fans remain effective even above 35C, as airflow still promotes evaporation. Rising UK heat extremes increase the importance of understanding effective cooling methods.

Experts explain how to maximise the cooling effect of electric fans during heatwaves, advising that windows remain closed during hot days and opened at night when outside air is cooler. Directing airflow over the whole body improves the effectiveness of sweating, while placing ice or water in front of a fan can slightly cool a room through evaporation. Social media misconceptions are addressed, including claims about temperature limits and methods that can cause electrical risks. Rising UK heatwave risks underscore the need for better understanding of cooling physiology.
