Brighter, bolder, hotter: Why female guppies can't resist orange Male guppies that glow with more orange aren’t just fashion-forward — they’re also significantly more sexually active. A UBC study reveals that brighter coloration is linked to virility and is genetically tied to brain development, suggesting a deeper evolutionary function. Researchers found that these bold hues aren't just for attracting mates, but are rooted in a vast, multi-chromosomal genetic system that enables tens of thousands of possible color pattern combinations. The work sheds light on how vibrant displays, behavior, and genetic fitness are intertwined in evolution.

Lemurs age without inflammation—and it could change human health forever What if humans didn’t have to suffer the slow-burning fire of chronic inflammation as we age? A surprising study on two types of lemurs found no evidence of "inflammaging," a phenomenon long assumed to be universal among primates. These findings suggest that age-related inflammation isn’t inevitable and that environmental factors could play a far bigger role than we thought. By peering into the biology of our primate cousins, researchers are opening up new possibilities for preventing aging-related diseases in humans.

Why monkeys—and humans—can’t look away from social conflict Long-tailed macaques given short videos were glued to scenes of fighting—especially when the combatants were monkeys they knew—mirroring the human draw to drama and familiar faces. Low-ranking individuals watched most intently, perhaps for self-protection, while high-strung ones averted their gaze.

Bigger crops, fewer nutrients: The hidden cost of climate change Climate change is silently sapping the nutrients from our food. A pioneering study finds that rising CO2 and higher temperatures are not only reshaping how crops grow but are also degrading their nutritional value—especially in vital leafy greens like kale and spinach. This shift could spell trouble for global health, particularly in communities already facing nutritional stress. Researchers warn that while crops may grow faster, they may also become less nourishing, with fewer minerals, proteins, and antioxidants—raising concerns about obesity, weakened immunity, and chronic diseases.

What happens when bees can’t buzz right? Nature starts falling apart High heat and heavy metals dampen a bumblebee’s trademark buzz, threatening pollen release and colony chatter. Tiny sensors captured up-to-400-hertz tremors that falter under environmental stress, raising alarms for ecosystems and sparking ideas for pollination robots.
