Science News! Let’s take a look at some of the important developments in science this week…
First, gravitational waves have been detected a second time by an international team of physicists and astronomers. These type of waves were predicted to exist by Einstein’s general theory of relativity but it was thought they were too weak to ever be measured. As with the first detection these waves were caused by the tight orbit of two black holes. Read more from Phys.org here.
Second, the level of CO2 in the atmosphere in Antarctica has reached 400 parts per million for the first time in 4 million years. This means that even remote regions are catching up with the increasing CO2 levels of more populated areas. Read more from Scientific American here.
Third, a study has found 15 reefs among 2,500 studied across the world that are not dying as quickly as predicted. These spots show some similarities in how they are being managed and conserved that could help shed light on how to manage other reefs that are not fairing as well. Read more from NPR here.
