'Red snow' spotted in Alps

As the summer months approached, ‘red snow’ was seen in the high parts of the Alps. Scientists explained that the proliferation of microalgae causes the snow to change color.

seen in the high parts of the Alpsred snow‘ prompted scientists to act. In the statement made by the scientists, it was noted that the proliferation of microalgae causes the snow to change color, and this is due to the increase in the amount of carbon dioxide in the air and climate change. Scientists stated that microalgae are also found in winter, but they are less visible due to their number and green color.

Eric Marechal, Director of the Cell and Plant Physiology Laboratory of the National Scientific Research Center, said in a statement, “From May, when the sun’s rays become very strong, the algae form a shield made of red molecules that act as sunscreen. This period coincides with the time they multiply, offering surreal landscapes on the summits.”

“RED SNOW ACCELERATES THE ICE-MELTING”

While it is said that the reason for the alarming increase in this situation in recent years may be the increase in carbon dioxide in the atmosphere, where the algae feed, it is estimated that microalgae accelerates the snow melt. “Unfortunately, the red color neutralizes the albedo effect of snow, facilitating the melting of glaciers,” said Director Marechal. This reflects the sun’s rays less, heats up and melts faster,” he said.

BENEFITS AGAINST CELL AGING

Stating that these microalgae can be used in the fight against cell aging due to their richness in antioxidants, Director Marechal said, “Sanguina molecules are rich in antioxidants and may attract the attention of the energy sector for health in the fight against aging of cells and even synthesizing new fuels.”
