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.

Apple snails can fully regrow their eyes, and their genes and eye structures are strikingly similar to humans. Scientists mapped the regeneration process and used CRISPR to identify genes, including pax6, as essential to eye development, raising hopes for future human vision restoration.

Despite our strong belief in dogs' ability to sense good from bad in people, new research shows they may not actually judge human character, at least not in the way we think. When dogs watched how humans treated other dogs, they didn’t favor the kinder person later. Even direct interactions didn’t sway their behavior. The study suggests dogs' reputational judgments might be more nuanced—or harder to study—than we realized.
