Danish Schoolgirls Attract International Attention With Unusual Wifi Cress Experiment

Five young Danish girls (Lea Nielsen, Mathilde Nielsen, Signe Nielsen, Sisse Coltau and Rikke Holm) received international attention from the science community recently with their interesting biology experiment regarding the safety of wireless devices. The girls took 400 cress seeds and placed them in 12 trays. Then they put six trays into different rooms at the same water temperature. They made sure to water them the same amount, and make sure each room received the same amount of sunlight. The only difference is that one of the rooms was exposed to wi-fi radiation, and the other was not. The results are rather alarming.

The cress seeds that were exposed to the router did not grow, and in some cases even became mutated. The cress in the room that had not been exposed to the wireless routers were healthy. “It is truly frightening that there is so much effect, so we were very shocked by the result,” said Lea Nielsen to Danish news site DR. These findings attracted the attention of renowned scientists from Denmark, Holland, and the U.K. when the girls entered their experiment in the Young Scientists Competition, where they made it to the finals.

In particular, the girls’ experiment impressed Olle Johanssen, from the Karolinska Institute in Stockholm. He plans on repeating the wifi cress experiment with his Belgian colleague Marie-Claire Cammaert at the Universit√© libre de Bruxelles. The implications of this experiment are of course pretty huge. We pretty much have no idea what the safety is of any of the many wireless devices we now use. If Dr. Johanssen can successfully replicate this experiment, it could have huge consequences on the entire electronics industry worldwide.

For now, the girls from Northern Jutland are playing it safe. “None of us sleep with the mobile next to the bed anymore. Either the phone is put far away, or it is put in another room. And the computer is always off,” said Lea.
