Atmospheric energy escaped from the Tibetan Plateau
Global warming is caused by extra energy trapped by green-house gases. Oceans are the major reservoir to store the extra energy. A recent study finds that the Tibetan Plateau may be another important window that removes excessive energy from the climate system. This enhanced energy loss is a response to the local climate change. (2015-04-01)

Tiny bird's migration route includes nonstop Atlantic crossing
By outfitting tiny birds with even tinier tracking 'backpacks,' an international research team -- led by a University of Guelph professor -- has confirmed what many scientists had long suspected: the blackpoll warblers annual migration route includes a three-day, nonstop flight over the Atlantic Ocean, a journey of more than 2,500 kilometers in some cases. The researchers found the birds flew directly over the Atlantic Ocean to reach their wintering grounds in South America. (2015-03-31)

A new spin on Saturn's peculiar rotation
The precise measurement of Saturn's rotation has presented a great challenge to scientists, as different parts of this sweltering ball of hydrogen and helium rotate at different speeds whereas its rotation axis and magnetic pole are aligned. A new method devised by a Tel Aviv University researcher proposes a new determination of Saturn's rotation period and offers insight into the internal structure of the planet, its weather patterns, and the way it formed.

Access to clean water -- a question of lifestyle and fairness
eThekwini is a municipality in South Africa, where the town of Durban is located. eThekwini is pointed out as being a good example with regard to the distribution of water to all inhabitants and in 2014, eThekwini was given the Stockholm Industry Water Award. However, many residents feel the system is unfair. For some, getting hold of clean water is a daily battle while others have swimming pools. This has been shown in a dissertation from the University of Gothenburg. (2015-03-23)
