Vertical hunting helps wild cats coexist in Guatemala’s forests, study finds

CORVALLIS, Ore. – A new study reveals that four wild cat species living in the same rainforest habitat in Guatemala reduce competition for food by hunting in different vertical zones, some in trees and others on the ground. Researchers from Oregon State University and the Wildlife Conservation Society of Guatemala used trail camera footage and DNA analysis of scat to study jaguars, pumas, ocelots and margays in the Maya Biosphere Reserve. They found that jaguars and ocelots primarily hunted ground-dwelling prey, while pumas and margays more frequently consumed animals that live in trees. Among the most surprising findings: Central American spider monkeys and black howler monkeys ...

Epigenetic changes regulate gene expression, but what regulates epigenetics?

LA JOLLA (November 21, 2025)—All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in each cell. Mistakes or failures in epigenetic regulation can lead to severe developmental defects in plants and animals alike. This creates a puzzling question: If epigenetic changes regulate our genetics, what is regulating them? Scientists at the Salk Institute have now used plant cells to discover that a type of epigenetic tag, called DNA ...

Football draft season raises concerns for young player welfare

The road to glory in the Australian Football League (AFL) is highly competitive, with as few as 0.01% of more than 640,000 young footballers and athletes from around Australia selected in the annual draft process. With so many young players pinning their hopes on selection, sport experts from Flinders University have surveyed more than 400 young male Australian footballers (16-18 years old) to evaluate the psychological impact on their mental health and wellbeing during a draft selection year. In the midst of adolescence and crucial stages of life, striving to compete at these levels raises concerns for the effects on young male players, says Associate Professor ...

ChatGPT is smart, but no match for the most creative humans

A new Australian study has smashed the myth that generative AI systems such as ChatGPT could soon replace society’s most creative playwrights, authors, songwriters, artists and scriptwriters. The existing large language models (LLMs) have a built-in mathematical ceiling on their creative capacity, meaning they will never rival the originality or ingenuity of the most creative individuals. That’s the finding from creativity expert David Cropley, a Professor of Engineering Innovation at the University of South Australia, whose study on the mathematical limits of generative AI has been published in the Journal ...

Rethinking where language comes from

A new Science paper challenges the idea that language stems from a single evolutionary root. Instead, it proposes that our ability to communicate evolved through the interaction of biology and culture, and involves multiple capacities, each with different evolutionary histories. The framework unites discoveries across disciplines to explain how the ability to learn to speak, develop grammar, and share meaning converged to create complex communication. For centuries, philosophers and scientists have wrestled with understanding how human language came about. Language defines us as ...

Theia and Earth were neighbors

About 4.5 billion years ago, the most momentous event in the history of our planet occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly happened afterwards has not been conclusively clarified. What is certain, however, is that the size, composition, and orbit of the Earth changed as a result – and that the impact marked the birth of our constant companion in space, the Moon. What kind of body was it that so dramatically altered the course of our planet's ...
