The mystery of an underwater “quack” sound in the ocean in the Southern Hemisphere has finally been solved. The sound appears in spring and winter in the Southern Ocean, and since it was first detected 50 years ago, scientists have been baffled as to what was making the noise – nicknamed “bio-duck.”
The answer to the mystery is minke whales. The quack sound is actually the underwater chatter of the whales, but scientists are still trying to determine when and why the whales make the unique sound. The solving of the mystery comes not long after another underwater noise was solved. The famous “bloop” noise was recently confirmed to be the sound of ice cracking underwater.
38 year-old Meb Keflezighi won the Boston Marathon to become the first American man to win the race since 1983. He wore the names of the three victims of the last year’s bombing on his bib, as well as the name of MIT Officer Sean Collier. After winning, Keflezighi flipped his sunglasses up as tears streamed down his face.
Jeff Bauman, who lost both of his legs in the bombing, attended the marathon with Carlos Arredondo, who became famous after being pictured helping Bauman after the blast. The two men were strangers at the time, but have since become close friends as the tragedy brought them together.
Boxer Rubin Carter, known as “Hurricane” has died age 76 after battling prostate cancer. He became internationally famous and a large part of the fight against racial injustice after he spent 20 years in jail for a crime he never committed. In 1966, two black men shot three white men at Lafayette Bar and Grill in Paterson, New Jersey.
Carter was convicted by an all-white jury based on the testimonies of two thieves with no real evidence. He was finally freed in 1985 after his convictions were set aside. It took many years of appeals, protests, and high-profile public advocacy to earn his freedom. Bob Dylan wrote his famous protests song “Hurricane” on the boxer’s story, and the 1999 film The Hurricane was also based on his life.
NASA astronauts have revealed evidence that there has been 10 times more asteroid strikes in the last decade. The majority of these strikes have been in remote areas of the Earth, so they go unnoticed. At an Earth Day event, the experts warned, “the only thing preventing a city-killer size asteroid is blind luck.”
BG12, the group behind the event, say there has been 26 explosions from asteroids in the last decade. The only reason these explosions have not been more public, according to the group, because of their remote locations. The goal of the group is to detect asteroids heading towards Earth earlier so they can be deflected.
Lee Joon-seuk, the captain of the South Korean ferry that sank several days ago, has been arrested on charges of negligence of duty and violation of maritime law. He has been criticized for ordering passengers to remain on the ship even as it tilted, delaying evacuation orders. Lee said he made the decision because he feared the passengers would “float away.”
29 people have been confirmed dead, with another 273 people still missing. 174 of the passengers were rescued. After being arrested, Lee appeared on TV and said, “”I am sorry to the people of South Korea for causing a disturbance and I bow my head in apology to the families of the victims.” He also admitted he had made a mistake in making such a sharp turn in the ship, which could’ve caused the tipping.
