Understanding how honey bees transport pollen pellets to their hive may inspire new ways to manufacture and manipulate soft materials, researchers say.
"Climate change is really a problem for health, and we are living and breathing the effects of climate change now," researchers warn.
Particular grass species may have greater effects on allergies and asthma than others, researchers find. The work could make pollen forecasts better.
Darwin observed that some plants produce less pollen (and some animals less sperm). New research clarifies how that can be an advantage.
When pollen resources are low, bumblebees damage plants to help drive more flowering so they can get more, researchers have found.
A wild dandelion's spiny pollen has evolved to attach to traveling bumblebees, report researchers.
A drop of fossilized amber from a mine in northern Myanmar contains not just a beetle but also 62 grains of pollen still clinging to its legs.
