Dandelion seeds can fly for incredible distances despite the fact that their tiny parachute-like bristles are broken up by large ... allowing wind to catch the seeds and carry them for long ...

Blowing dandelion seeds into the wind isn't just a pretty little way for kids (and adults) to waste away a warm afternoon outside. They’re also an exceptionally effective way for certain species ...

By setting up a tiny, delicate wind tunnel and carefully mapping the precise movement of air around the dandelion seeds, the researchers figured out what’s going on. The precise patterns of the little ...

On the ground, each of the team's tiny platforms can host up to four sensors, measuring temperature, light, humidity and pressure, and relay the data from up to 60 m (200 ft) away.

This hairy parachute closes when the air is humid, which often means the wind is weak. In drier, more windy conditions, dandelions widen their parachutes to better catch the wind so the seeds can ...

Other seeds are dispersed by the wind—such as the "winged" seeds from a maple tree that spin and "helicopter" through the air as they fall or the light feathery seeds from a dandelion that can ...

A dandelion only has between 100 and 110 filaments, or thread-like fibres, on the head of the seed. But it has four times more flight time than predicted by any fluid mechanics calculations.

The new sensors, adorned in a brilliant gold color, have a mass of about 30 milligrams, so they are heavier than the average dandelion seed. But they still have to travel about 330 feet in a light ...
