Vincetoxicum nakaianum tricks flies into pollinating it by imitating the smell of ants attacked by spiders. Ko Mochizuki stumbled upon this finding when he noticed flies clustering around the flowers and later confirmed their unusual preference. The study reveals the first known case of ant odor mimicry in plants, expanding our understanding of how diverse floral deception can be.

Gifted dogs can categorize toys by function, not just appearance. In playful at-home tests, they linked labels like “fetch” and “pull” to toys—even ones they’d never seen before. The findings hint that dogs form mental concepts of objects, much like humans, pointing to deeper cognitive abilities.

Bumble bees aren’t random foragers – they’re master nutritionists. Over an eight-year field study in the Colorado Rockies, scientists uncovered that different bee species strategically balance their intake of protein, fats, and carbs by choosing pollen from specific flowers. Larger, long-tongued bees seek protein-rich pollen, while smaller, short-tongued species prefer carb- and fat-heavy sources. These dietary preferences shift with the seasons and colony life cycles, helping bees reduce competition, thrive together, and maintain strong colonies.

Two independent research teams have unveiled near-complete reference genomes of the central bearded dragon, a reptile with the rare ability to change sex depending on both chromosomes and nest temperature. Using next-generation sequencing technologies from China and Australia, the projects uncovered the long-sought genetic basis of sex determination in this lizard.

Scientists have engineered a groundbreaking cancer treatment that uses bacteria to smuggle viruses directly into tumors, bypassing the immune system and delivering a powerful one-two punch against cancer cells. The bacteria act like Trojan horses, carrying viral payloads to cancer’s core, where the virus can spread and destroy malignant cells. Built-in safety features ensure the virus can’t multiply outside the tumor, offering a promising pathway for safe, targeted therapy.
