POOR SUBSTITUTES
The World Health Organization's announcement on aspartame being possibly carcinogenic to humans has reignited the debate on health hazards of sugar substitutes. Not only is the evidence on safety of sugar substitutes sketchy, their role in controlling blood sugar levels, too, remains inconclusive. On the contrary, studies increasingly indicate that sugar substitutes contribute to factors that lead to cardiovascular diseases, cancer, and, quite ironically, diabetes.

Claudia Goldin on Career and Family
A century ago, it was a given that a woman with a college degree had to choose between having a career and a family. Today, there are more female college graduates than ever before, and more women want to have a career and family, yet challenges persist at work and at home. Claudia Goldin, who has won this year's Nobel Prize in Economic Sciences traces in her book Career and Family how generations of women have responded to the problem of balancing career and family as the twentieth century experienced a sea change in gender equality, revealing why true equity for dual career couples remains frustratingly out of reach.

CAUGHT UNAWARES
In a rapidly changing climate, early warning systems are a critical, cost-effective way of protecting people from extreme weather. But effective implementation of the system to protect every person on Earth by 2027, as envisioned by the UN, is a huge task. Countries highly vulnerable to climate change impacts lack the know-how or finance. Technologies, too, need upgrading to accurately predict disasters.
