Iceland, the only Arctic nation that considered itself mosquito-free, lost that title in December 2015, was awarded by an editorial published in Science magazine. It indicated that global warming in the North Pole, which is four times faster than in the equatorial regions, has led to changes in Iceland’s ecosystems. Three species of mosquitoes appear. The most recent example is the appearance of three species of mosquitoes in Reykjavik, last Dec…
For the first time in history, mosquitoes have been located in Iceland. In particular, an expert has found three specimens of the same species in a garden in Kjós, north of the country’s capital, which constitutes an unusual fact, since until now, the geographical isolation and climate of the island had led to no species of mosquito being able to live there.
DAILY DOSE: B Cells May Play an Important Role In Exercise; Iceland’s Mosquitoes Signal a Bigger Arctic Blind Spot
B Cells Join the Physiology of Exercise: Immune cells best known for fighting infection may also help power exercise. In a new mouse study, researchers found that animals with depleted B cells performed worse on endurance and strength tests than control mice, whether the B-cell loss was genetic or induced by antibody treatment. The team then traced the effect to metabolism. Mice lacking B cells showed lower post-exercise glutamate levels in musc…
