Costa Rica is the happiest place on Earth, according to a 2009 survey by a London economic think tank. Credit the strong coffee and refreshing batidos — milkshakes with fresh banana, papaya, mango or some other tropical treat — and the country’s pura vida attitude that celebrates living life to the fullest.

Local coastal impacts underestimated from sea-level rise

Most studies indicate that sea levels will rise over the next century due to melting glaciers, more ice breaking off the Antarctic ice sheet and thermal expansion — and there is great variation in how much scientists estimate seas will rise. But that’s not even the most important question, according to a new study. Instead, researchers should be looking at relative sea-level rise — how much rising seas will affect individual regions. And when you break it down by region, the study suggests, the outlook isn’t promising.

The rapid climate change forced the Sahara’s human inhabitants to adapt — some people became more sedentary and settled near oases while others took up cattle herding and traveled between the desert’s dwindling resources.

Bids in space: When should we outsource government science?

Government research and development has its limits: Time, money and bureaucracy can all hamper the timely progress of research. As a result, many federal agencies are looking to private companies to help drive new innovation and keep costs down — but it’s never that simple. Two current hot-button topics — returning humans to space and geoengineering — highlight a range of issues related to how private and public investment in science can coexist. This month, we focus on NASA.

Offbeat Betting: Volcano betting gathering steam

You never quite know when a given volcano is going to erupt — but you can bet on it.
