WiFi routerAccording to an experiment conducted by high school students in Denmark, radiation from wireless routers affected the growth of plants, to be more precise, garden cress seeds.

What instigated these ninth graders to conduct this experiment? They wanted to figure out why they had trouble concentrating after sleeping with their cellphones in close proximity.

In the rudimentary experiment, they placed separate trays of garden cress seeds near wireless routers (about the same microwave radiation as a cellphone) and in a separate room without routers. The girls carefully monitored and controlled factors such as room temperature, sunlight and water for both sets of seeds for 12 days.

What were their finding? They found the garden cress seeds placed near the router were brown and shriveled, while the once in the radiation-free room had sprouted into a green bush.

Needless to say, the little biology experiment has caught the attention of the scientific community. What’s more, the Danish national science fair recognized the students for their work.
