Teaching children to read well from the
start is the most important task of elementary schools. But relying on educators
to approach this task correctly can be a great mistake. Many schools continue to

This is one of the expected conclusions of an official government report to be published this week. The report is expected to call for the mobile phone industry to refrain from promoting phone use by children, and start labeling phones with data on the amount of radiation they emit.
The independent Expert Group on Mobile Phones, chaired by former government chief scientist William Stewart, has spent eight months reviewing existing scientific evidence on all aspects of the health effects of using mobile phones. Its report is believed to conclude that because we don’t fully understand the nonthermal effects of radiation on human tissue, the government should adopt a precautionary approach, particularly in relation to children.
There is currently no evidence that mobile phones harm users or people living near transmitter masts. But some studi
