Scientists at The Florida Aquarium have figured out how to get ridged cactus coral to reproduce in the lab for the first time. It was one of the many species rescued from Florida鈥檚 waters after a major disease outbreak in 2014 wiped out nearly 35% of the reef. Since the lab鈥檚 spawning success in early April, more than 350 coral babies have been released into the ocean, where scientists hope they will get to work rebuilding the third-largest coral reef in the world.聽鈥淪cientific breakthroughs that have a direct impact on protecting and restoring our natural environment is why we exist,鈥� said Roger Germann, president and CEO of The Florida Aquarium. The aquarium participates in Project Coral, a program that aims to repopulate the world鈥檚 diminishing coral reefs.聽(CNN, Yale Environment 360)

2. Chile

European Southern Observatory (ESO) astronomers in Chile found a star 鈥渄ancing鈥� around a black hole in the Milky Way on April 16, as predicted by Albert Einstein鈥檚 Theory of General Relativity. Einstein鈥檚 theory, published in 1915, posits that what we perceive as the force of gravity arises from the curvature of space and time.聽The ESO discovery is a result of astronomers precisely measuring the orbit (at 16 years per orbit) of a star tracing a rosette-shaped pattern around a massive black hole, rather than the elliptical orbit predicted by Newtonian physics. The star is circling the black hole Sagittarius A*, located at the center of our Milky Way galaxy. The black hole has a mass estimated to be聽4 million times that of the sun. (Reuters)

3. Austria

Austria shut down its last coal-fired power plant on April 17, as part of the country鈥檚 plan to end the use of fossil fuels by 2030.聽 The government plans to shutter the remaining gas-fired and oil-fired power plants by the end of the decade to complete its transition to generating energy from renewable sources.聽In a massive overhaul of the European energy industry, many countries are phasing out or immediately ending the use of coal-fired power plants. Sweden became the third European country to exit coal following Austria and Belgium, which shut down its last coal-fired plant in 2016. Six European countries are expected to follow suit by 2025 or earlier. (The Independent, CNBC)

4. Saudi Arabia

Saudi Arabia has ended the death penalty for crimes committed as minors. On April 26, its state-backed Human Rights Commission announced the royal decree by King Salman bin Abdulaziz Al Saud.聽Instead of execution, individuals who committed crimes as minors will serve a prison sentence of no longer than 10 years in juvenile detention centers.聽Saudi Arabia holds the record for the highest number of executions after Iran and China, according to Amnesty International. In 2019, the kingdom executed a record 184 people. 鈥淭he decree helps us in establishing a more modern penal code,鈥� said commission President Awwad Alawwad. Saudi Arabia also banned flogging as a form of punishment in the same week. (BBC, Al Jazeera)

5. Ethiopia

A group of entrepreneurs in Ethiopia鈥檚 capital, Addis Ababa, is helping to reduce the use of plastic shopping bags and provide a livelihood for women who are deaf or partially deaf. Teki Paper Bags, an enterprise developed by women, has sold almost 1 million handmade paper bags. Ethiopia lags behind other East African countries, such as Rwanda and Kenya, in reducing its plastic consumption and production primarily because of cost.聽Teki, which employs 18 deaf workers and has more than 50 clients, is challenging the narrative that paper bags are too expensive 鈥� all through sign language. The entrepreneurs say their emphasis on the social benefit of creating jobs for people with disabilities, rather than lecturing about the environment, is the key to their success. 鈥淲ith our paper bags we want to provide people with the opportunity to change the lives of deaf people, and through this create an alternative way to fight plastic,鈥� says Clement Piguet, one of Teki鈥檚 co-founders.

6. Japan

Japan鈥檚 greenhouse gas emissions hit a record low for the year ending in March 2019, since the country started measuring greenhouse gas emissions in 1990. The world鈥檚 fifth-largest carbon emitter aims to cut emissions by 26% from its 2013 levels by 2030. Japan seems to be on track with the latest 3.9% drop, for a total 12% reduction in emissions.聽After the 2011 nuclear disaster in Fukushima, the country鈥檚 greenhouse gas emissions surged because all of its operable nuclear power plants were taken offline. However, wider use of renewable energy and a gradual return to nuclear power, including the restart of nine reactors, allowed Japan to consistently see a reduction in emissions for five straight years.
