Danish Schoolgirls Test Wi-Fi Risks with Garden Cress

Let’s hear it for smart Danish schoolgirls! This story recently ran on www.geek.com:

School experiment discovers garden cress won’t germinate near a router

Garden cress is a fast growing and edible herb that will sprout in just a small amount of slightly alkaline water. But there is one exception to that rule, and is has scientists scratching their heads.

A group of 5 girls have carried out a science experiment at Hjallerup School in North Jutland, Denmark that saw garden cress seeds placed in 12 tubs and split into two batches. Both batches were placed in different rooms that remained the same temperature, and were given the same amount of water and sunlight over the course of 12 days.

You’d expect both batches of 6 tubs to grow equally well, but one set didn’t even germinate. The reason? They were placed next to two routers. Although it’s unclear exactly why this happened, it is thought that the radiation produced by the routers is what stopped the seeds germinating.

The girls’ experiment was geared towards testing the potential impact of phone radiation on surrounding objects. They didn’t have phones to use though, so decided the routers were a good alternative. The experiment has certainly caught the interest of the international science community and is set to be repeated in a more controlled environment. One of the first controlled experiments will be carried out by Professor Olle Johansson from the Karolinska Institute in Stockholm. Hopefully it will shed more light on why this is happening…
