Does a lifetime of vigorous exercise increase the risk of developing ALS?

A new study suggests that vigorous exercise during leisure time is not associated with an increased risk of developing amyotrophic lateral sclerosis (ALS). However, intense physical activity at work hours was linked to a higher risk, possibly due to repetitive motion or exposure to chemicals. Moderate exercise, even after symptoms begi...

Climate change will diminish the number of birch trees in Bavaria by the end of the century

A mathematical model based on 30 years of pollen data predicts a decline in pollination in Bavarian forests due to climate change. The study forecasts a reduction in birch trees in the region by the end of the century, with warmer summers initially favoring pollen production but ultimately leading to a decline in plant populations.
