This study compares the noise levels at the cold-water coral Tisler reef, before and after the closure of the border between Norway and Sweden, which occurred as a direct result of the COVID-19 pandemic. The Tisler reef is a marine protected area located under a ferry “highway” that connects Norway and Sweden. Cold-water coral reefs are recognised as being important hotspots of both biodiversity and biomass, they function as breeding and nursing grounds for commercially important fish and are essential in providing ecosystem functions. Whilst studies have shown that fishery, ocean warming, and acidification threaten them, the effects of noise pollution on cold-water coral reefs remains unstudied. To study the severity of noise pollution at the Tisler reef, a long-term acoustic recorder was deployed from 29 January 2020 until 26 May 2020. From 15 March COVID-19 lockdown measures stopped passenger vessel traffic

Can long-term stress lead to heart attacks? Most people would probably answer in the affirmative, but the scientific evidence of this is scarce. A new study by researchers from Linköping University in Sweden reveals that the levels of the stress hormone cortisol were increased in the months preceding a heart attack. The results, published in
Scientific Reports, suggest that long-term stress is a risk factor for heart attacks. The levels of the stress hormone cortisol differed between people who have had a heart attack and those not affected. This suggests that cortisol in hair may be a new risk marker for heart attacks. We must take stress seriously , says Professor Tomas Faresjö from the Department of Health, Medicine and Caring Sciences at Linköping University, principal investigator of the study.
