Plants in the Arctic are growing taller because of climate change, according to research from a global scientific collaboration.

A University of Adelaide-led team of researchers has found a link between sudden cardiac death (when the heart suddenly stops beating) and a common heart condition known as mitral valve prolapse that affects around 12 in every 1000 people worldwide.

Since December 2016, Brazil has been grappling with its worst yellow fever outbreak for several decades. To date, there have been 2,043 human cases including 676 fatalities, mainly occurring in ten Brazilian states including Rio de Janeiro and São Paulo. These two states, the most heavily populated in Brazil, had been free of yellow fever for nearly 70 years. Research by scientists at the Institut Pasteur and the Institut Oswaldo Cruz has demonstrated that the yellow fever virus can be transmitted via Aedes albopictus, the tiger mosquito. This opportunistic species is capable of colonizing both urban and forest areas.

The Sherpa people of the Himalayas have long been recognized for their unique ability to excel physically in the thin air of higher altitudes. But new research from UBC’s Okanagan campus, published last week in the Journal of Physiology, now suggests that their specially adapted muscles give them up to twice the resistance to muscle fatigue of lowlanders.

While a warming climate in recent decades may be a factor in the waning of some local populations of frogs, toads, newts and salamanders, it cannot explain the overall steep decline of amphibians, according to researchers.
