WHO urges ‘extreme caution’ over coronavirus slowdown

World
An apparent slowdown in the spread of the coronavirus epidemic should be treated with "extreme caution", according to the head of the World Health Organisation (WHO)."This outbreak could still go in any direction," the WHO's director general, Dr Tedros Adhanom Ghebreyesus, said. Earlier, China reported its lowest number of new coronavirus cases in two weeks.

U.S. military bases to face an increase in extreme heat

U.S. military bases to face an increase in extreme heat

Science
Nov. 11 (UPI) -- Over the next three decades, members of the United States military stationed on bases in the contiguous U.S. could experience an extra month of extreme heat each year, as climate change continues unabated. Researchers with the Union of Concerned Scientists used climate models to simulate temperatures on U.S. military bases under a range of warming scenarios. They published their findings in a new report. "Our results show that with no action to reduce global heat-trapping emissions, on average, by mid-century U.S. installations would experience nearly five times as many days with a heat index above 100°F as they have historically," Kristy Dahl, a senior climate scientist and the lead author of the study, wrote in a blog update. "These results imply that living, working,

‘Extreme corals’ discovered in Great Barrier Reef’s mangrove lagoons

Science
Aug. 29 (UPI) -- Corals capable of withstanding extreme conditions have been found inside mangrove lagoons around Australia's Great Barrier Reef. Scientists found 34 coral species living in the "hot spots" of coral resilience. Inside the lagoons, the so-called "extreme corals" are exposed to high acidity, low oxygen and highly variable temperature conditions. By studying coral species that have adapted to rapidly shifting ocean conditions, scientists can gain insight into how coral will respond to climate change and other environmental stressors. "This highlights the need to study environments that would usually be considered unfavorable to corals in order to understand how stress tolerance in corals works," Emma Camp, research fellow at the University of Technology Sydney, said in a new...

Google directing people to extreme content and conspiracy theories

Technology
Google is directing people towards misinformation and conspiracy theories by placing YouTube videos prominently in its search results, an investigation by Sky News has found.Sky News found a number of search terms where extreme content and conspiracy theories featured highly in Google's results - including several topics of public concern. They appeared in the box marked "Videos", which Google places on the first page of certain searches, usually among the top results. For instance, a search for the phrase "5G birds" - a search term relating to a conspiracy theory that upgraded mobile networks will kill birds - showed an article debunking the theory by fact-checking organisation Snopes as the first line.Immediately underneath, the Videos box presented three YouTube videos repeating the cla...
Heart strain from extreme exercise doesn’t cause permanent damage, study says

Heart strain from extreme exercise doesn’t cause permanent damage, study says

Health
June 27 (UPI) -- Performing strenuous exercise, like taking part in a 24-hour ultramarathon, won't permanently hurt a person's heart, new research shows. High-intensity running puts more strain on the heart and drives up biomarkers that would otherwise indicate cardiac risk, according to a study published in June in Heliyon. However, those elevated biomarkers don't cause permanent damage. "Experienced runners performed with greater intensity and speed which placed strains on their hearts," Rodrigo Hohl, a researcher at Federal University of Juiz de Fora and study co-lead investigator, said in a news release. "Novice runners ran with less intensity, which resulted in lower cardiac biomarker levels." The study included 25 people who took blood tests before and after they ran in a 24-hour u...
