Debate over Wi-Fi risks
A British expert in microwave radiation warns that Wi-Fi connections in classrooms could cause DNA damage in children exposed to these microwaves. Contrary to the claims of school board officials and Health Canada that there is no health threat from this technology, the physicist, whose warnings are echoed by a health sciences professor at Trent University, states that low level frequencies can cause DNA damage in growing children, who are more vulnerable than adults.
How much time do you spend connected to Wi-Fi?

Digging deeper into doomed ship
A scientific expedition to the Titanic's wreck will survey the state of the hull and determine how much of the ship has already rusted away. Scientists also plan to do a complete inventory of the hundreds of thousands of artifacts scattered throughout the ship's debris field. Researchers will use advanced imaging techniques and sonar to recreate a detailed 3D model and virtually 'raise' the Titanic from the seabed.

Sisters and brothers unite!
A child psychologist reports that it is more important to encourage positive sibling behaviour than it is to discourage negative sibling behaviour. Parents should create opportunities for family fun.

Sibling relationships can set a standard for how you form future relationships with others.
How well do you get along with your siblings?
