Pollen has a surprising problem — and honeybees have found a way around it
Honeybees can apparently detect when their food has the wrong balance of essential nutrients and adjust how much they eat to avoid potentially harmful excesses. They also transform pollen into remarkably well-balanced “baby food” for their larvae, revealing a sophisticated nutritional strategy hidden inside the hive.
Butterfly lilies wing their way to Science
Many animals and plants show left-right differences in how their bodies or organs are arranged, but we still know little about how such asymmetries evolve or how genes control them in natural populations. Mirror-image flowers, in which female and male sex organs are deflected to opposite sides in left- and right-handed forms, provide a notable example of such asymmetry. Here, we studied South African butterfly lilies, where individual plants produce only left- or right-handed flowers. Their mirror-image flowers promote outcrossing by depositing pollen from each floral form onto a specific region of a pollinator’s body that matches the stigma position of the opposite form. This suggests that selection for efficient pollen transfer between forms maintains this natural polymorphism. Our work uncovers a hemizygous supergene that coordinates the left-right orientation of female and male sex organs in mirror-image flowers by linking two independently acting genes for style and stamen handedness in a single, nonrecombining genomic segment. This architecture ensures the coinheritance of a matched pair of organ orientations that is essential for efficient cross-pollination between floral forms. At the developmental level, we show that floral handedness emerges from the interaction between an intrinsic tissue chirality and a gravitropic response that orients the style and median stamen relative to gravity. Together, these findings reveal how a supergene, hormone and microRNA signaling, tissue chirality, and an external physical cue combine to produce and maintain a stable left-right polymorphism in natural plant populations.

How tiny pollen grains helped solve a brutal murder: The fascinating science behind nature's invisible crime scene evidence
Blood, fingerprints, and weapons aren't the only evidence investigators look for at a crime scene; pollen is another. Pollen grains are one piece of evidence that has helped solve some of the highest-profile murder cases in recent years, one grain at a time.
Scientists solve a 30-year rye pollen mystery that could transform cancer research
Scientists have finally solved a nearly 30-year-old mystery surrounding two unusual molecules found in rye pollen that once showed an intriguing ability to help animals fight tumors. By determining their exact 3D structures, researchers have unlocked the blueprint needed to investigate how these natural compounds interact with the immune system and which parts may be responsible for their cancer-fighting effects.
Butterfly that barely ages could help unlock longevity secrets
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species. Even more surprising, some show little sign of physical decline as they age. Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helping them stay healthy for longer.
