geography matters: A study shows that geography plays an important role in determining the global emissions of carbon dioxide (CO2). As per the research, conducted by Eric Neumayer of the London School of Economics and Political Science, countries with high average number of frost days produce more CO2 emissions because of heating requirements. On the other hand, nations having access to renewable energy resources can have lower emissions. Big countries with scattered populations also emit more CO2 than nations with densely located population. This is due to their higher transportation requirements.

chicken nitty-gritty: As per the US National Human Genome Research Institute, a draft genome of the ancestors of domestic chicken is now in a public database. The Beijing Genomics Institute of the Chinese Academy of Sciences has also produced a map showing genetic variations between chicken and their ancestor. A better understanding of the genetic make-up of chicken is expected to boost research on diseases like SARS.

During their study, the researchers found that most households using products containing antibacterial agents suffer from as many common infections (like coughs and colds) as households using the regular products.
