I tried to find the article about economy in Canada but I found only the article about Science In Canada. I had no choice. David Valentine - professor at the University of California, thinks that measuring the leaked methane gas in the sea water will give us a much more accurate reading.

And also I leant that measuring methane to determine extent of oil spill. Knowing how much oil has spilled from the Deepwater Horizon Rig in the Gulf of Mexico is vital to calculate the environmental impact and to inform the clean up crews. But determining how much oil has leaked has proved very difficult.

I think it is interesting that astronomer Professor Martin Rees chooses the moment when fellow Cambridge astronomer, Martin Ryle revealed that radio waves in deep space enabled him to explore the distant universe.

Unfortunately, I got to know that scientists in Canada are using pond snails to investigate the effects of drug abuse. The snail's simple nervous system makes the creature a very useful model for how addiction to methamphetamine might affect our brains, and in particular how certain drugs can affect our memory.
