Estonia plans to test the DNA structure of 100,000 residents and give advice regarding their predispositions to certain diseases so that they could adopt healthier lifestyles and take preventive measures.
“We want to invest in preventing or delaying the onset of common chronic diseases by using genetics to identify people at high risk,” says Jevgeni Ossinovski, Estonia’s minister of health and labour.
The country plans to do it eventually for the entire population.

Why are Animals Altruistic?

Researchers at the Laboratoire d’Écologie at the University Pierre and Marie Curie (Ecole Normale Supérieure/CNRS) and the Royal Holloway College (London, United Kingdom) have just explained the evolution of altruistic behavior in animals.

In nature animals have been observed cooperating, and the detection of a genetic predisposition to this type of behavior contradicts Darwin’s theory of evolution which predicts a better survival rate for the most selfish animals. The use of mathematic modeling has provided a new explanation for the surprising persistence of this type of behavior which appears, at first sight, to be detrimental to the animal adopting it.
