New research reveals that cacti are among the fastest-evolving plant groups on Earth, driven by rapid changes in flower shape rather than size or pollinators. The findings from the University of Reading challenge long-held ideas about speciation dating back to Darwin. Scientists analyzed data from more than 750 species to reach their conclusions.

A new analysis from Queen Mary University of London proposes that the universe's physical constants occupy a narrow range allowing liquids to flow properly inside living cells.

Researchers have identified a new venomous pitviper species in the misty mountains of western Sichuan, China, previously mistaken for a common snake. Named Trimeresurus lii after the philosopher Laozi, the Huaxi Green Pitviper features distinct markings and eye colors between males and females. DNA analysis confirmed its unique evolutionary lineage in a global biodiversity hotspot.

OpenAI has launched GPT-Rosalind, a large language model trained specifically on biology workflows. The model, named after scientist Rosalind Franklin, aims to address challenges in handling massive biological datasets and specialized subfields. Access is currently limited to US-based entities due to safety concerns.

Male Japanese pygmy octopuses take extra care to safeguard their third right arm, the hectocotylus, which plays a key role in reproduction. Researchers at Nagasaki University observed that males resist touching this arm and use it less for risky tasks than females do. The findings highlight an evolutionary adaptation to protect this vital appendage.

Researchers at Oregon Health & Science University have identified hidden fluid flows inside cells that rapidly transport proteins to the leading edge, challenging traditional views of cellular movement. The discovery, made during a classroom experiment, could explain why some cancer cells spread aggressively. The findings appear in Nature Communications.
