Rising greenhouse gas emissions could see the size of extreme floods in the Central Himalayas increase by between as much as 73% and 84% by the end of this century.
The fossilized remains of a very unlucky bird that lived about 120 million years ago reveal something that's rarely clear from fossils: the animal's cause of death. The cluster of rocks in the bird's throat tells scientists that it probably choked to death. The reason why this bird was swallowing rocks in the first place is more of a mystery, and one that gets into the bigger picture of dinosaur and bird evolution.
KUALA LUMPUR / GLASGOW — As the world races to meet ambitious climate targets, nature-based strategies are gaining unprecedented traction—and biomass is stepping into the spotlight not just as renewable fuel, but as a powerful carbon sink. On December 17, 2025, leading sustainability expert Prof. Dato’ Dr. Agamutu Pariatamby FASc, Senior Professor at the Jeffrey Sachs Center on Sustainable Development, Sunway University (Malaysia), will unveil groundbreaking insights into how bio-based carbon capture can deliver up to 6.7 gigatonnes of CO₂-equivalent (GtCO₂e) in annual mitigation potential by 2050—according to IPCC (2022) estimates.
For decades, paleontologists argued over the lone skull used to establish the distinct species Nanotyrannus. Was it truly a separate species or simply a juvenile Tyrannosaurus rex? A new paper published in Science has definitively shown that Nanotyrannus is, in fact, nearly fully grown and not an immature T. rex, at the same time revealing new insights into how these giant predators achieved such terrifying sizes so quickly.
A multi-institutional team, including Dinosaur Institute Postdoctoral Fellow, Dr. Zach Morris, examined the much-debated Nanotyrannus holotype—the specimen used to name a new species—particularly its throat bone. The team examined the bone’s microscopic structure, comparing it to those of living birds, crocodilians, and extinct dinosaurs—including the Dino Hall’s singular T. rex growth series—to establish that Nanotyrannus, while smaller, was a fully grown and distinct predator in an ancient ecosystem more diverse than previously imagined. Slightly less than half the size of their massive adult cousins, Nanotyrannus competed with juvenile T. rex for prey in Late Cretaceous North America.
