D. rex's fruiting bodies were discovered in the forests of Yunnan Province. (Song et al., Frontiers in Fungal Biology, 2026) Yunnan Province in China is famous for its mushrooms and fungi, but somehow, scientists have only just come across a new species that has rightly earned the name 'king'. Named Dianjunus rex (or D. rex for short), its gigantic, club-like fruiting bodies can grow up to 50 centimeters tall, which is about one and a half feet, or the height of a traffic cone. A researcher holds up two D. rex fruiting bodies to show off their impressive size. (Provided by Indunil Senanayake) But its impressive size is not the only exciting thing about this fungus. Its genes also contain clues about a major moment in the history of life on Earth. Mycologist Indunil Senanayake of the Chinese Academy of Sciences and her colleagues describe the new species in a paper published in Frontiers in Fungal Biology. D. rex is the only known member of its family, Dianjunaceae. "This remarkable species… provides a rare window into the evolution of extreme fungal body forms," says Senanayake.

A colossal prehistoric snake that lived in India about 47 million years ago may have been one of the largest snakes ever to exist. Known as Vasuki indicus, the ancient reptile could have reached an extraordinary 15.2 meters (50 feet) in length, putting it in the same league as Titanoboa, the enormous extinct snake long regarded as the largest ever discovered. The remarkable discovery, described in 2024 in the journal Scientific Reports, came from fossils unearthed in Gujarat, western India. Researchers estimate that Vasuki measured between 10.9 and 15.2 meters (36 and 50 feet) long, although its exact size remains uncertain. Its enormous body and unusual evolutionary history offer a glimpse into a time when giant snakes inhabited the warm, tropical landscapes of ancient India.

In June 2025, scientists released extraordinary footage of Pacific sleeper sharks in the South China Sea. It was the first time the species had been caught on camera in this part of the world, offering vital new clues about the behaviour and distribution of these elusive deep-sea giants.
