Canada remains the seventh happiest country in the world, according to a new report co-edited by CIFAR Distinguished Fellow John Helliwell.
The extreme wet and dry periods Mongolia has experienced in the late 20th and early 21st centuries are rare but not unprecedented and future droughts may be no worse. An international team of researchers developed a climate record stretching 2,060 years into Mongolia's past using tree rings. The team then combined the tree-ring record of past climate with computer models that can project future regional climate.
The study, published in Nature Ecology & Evolution and led by a multidisciplinary research team at the Max Planck Institute for the Science of Human History, reveals that migrations of people from the Bismarck Archipelago in Oceania to the previously settled islands of the Pacific began as early as 2,500 years ago, much earlier than previously thought. Vanuatu presents an unprecedented case, where the population's genetic ancestry but not its languages were replaced.

Researchers have made a major breakthrough in the assessment of language development among bilingual families and in the identification of those children who require extra support to improve their language skills.
A thousand-year-old tooth has provided the first clear genetic evidence that the Taíno -- the indigenous people whom Columbus first encountered on arriving in the New World -- still have living descendants today, despite erroneous claims in some historical narratives that these people are extinct. The findings are likely to have particular resonance for people in the Caribbean and the US who claim Taíno ancestry, but have until now been unable to prove definitively that such a thing is possible.
Hurricanes spawn most of the largest storm surges in the northeastern US, right? Wrong, according to a study by Rutgers University-New Brunswick scientists. Extratropical cyclones , including nor'easters and other non-tropical storms, generate most of the large storm surges in the Northeast, according to the study in the Journal of Applied Meteorology and Climatology. They include a freak November 1950 storm and devastating nor'easters in March 1962 and December 1992.
Overtly racially motivated rhetoric is becoming increasingly acceptable in Republican politics in the US. Two Italian researchers argue that this can partly be traced back to the conservative Tea Party movement which has reshaped the Republican party's identity away from its traditional conservative axioms to one that is more nativist and racially tinged. Luigi Leone and Fabio Presaghi from the Sapienza University of Rome have published their findings in Springer's journal Race and Social Problems.
Why do some Westerners attack Muslim minorities and asylum seekers and why do some Muslims support and engage in terror against the West? New research suggests that the reasons for such extreme behaviour might be the same in both groups. The results have now been published in the European Journal of Social Psychology.
An ethnic population at high risk for Type 2 diabetes achieved significant control of the disease through participation in community-based health programs, according to a randomized controlled trial published Jan. 31 by researchers at NYU School of Medicine's Department of Population Health in the journal Clinical Diabetes.
