Concern lags over heart health
On your mark – ATLAS computing grid ready

Concern lags over heart health
One in three adults - an estimated 424 million people worldwide – are unaware of what healthy blood pressure levels should be. And while one in three of the adults participating in a global survey are at risk from heart disease only one in 10 are concerned about their heart health. Those are key findings of a survey, Do You Know Your Numbers?, conducted in 15 countries by the World Hypertension League and Canadian pharmaceutical company Novartis. The survey’s aim was to determine participants’ general health knowledge levels. WHL secretary Arun Chockalingham, director of SFU’s global health program, says the survey results show a critical need for greater promotion of heart health. Cardiovascular disease is the world’s number one cause of death.

On your mark – ATLAS computing grid gets ready
Despite a delay in the start of the long-awaited ATLAS project, Oct. 3 will be a banner day for thousands of scientists worldwide – that’s when the world's largest computing grid marks its readiness to accept data from the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland – a key step in the kickoff of the ATLAS experiment. Scientists will gather at Vancouver's TRIUMF facility to celebrate the start of the Worldwide LHC Computing Grid (WLCG), which comprises over 140 high-performance computing sites around the world. More than fifteen million gigabytes of data will be produced annually from the hundreds of millions of subatomic collisions expected every second inside the LHC, a gigantic machine stretching 27km in circumference. SFU physicist Michel Vetterli, project leader for the ATLAS Canada Data Analysis Centre, will be at TRIUMF, while SFU physicist Dugan O'Neil will be in Geneva to witness the event. Both can comment on the relevance of the experiment, their roles and why people should care about it.
