2000-Year-Old Human Skeleton Discovered from Antikythera Shipwreck

Archeologists have excavated a partial human skeleton on the famous ancient Greek shipwreck. The shipwreck has already yield a number of statues, sculpture and artifacts but this is the first time in many years when a human skeleton is discovered in the wreckage which has been lying in the ocean floor off Greek island of Antijythera for more than 2000 years. 

The skeleton is possibly belong to a young man aboard ship and is remarkably well preserved. Once researchers receive the permission from Greek authorities, the skeleton will be sent to the lab for DNA analysis and it can provide insight into the people traveling on the ship hundreds of years ago.

‘Out of Control’ Chinese Space Station will Crash to Earth in 2017

China’s first space station Tiangong-1 will meet a fiery demise next year. Chinese officials have confirmed that their space station is out of control and heading straight towards the Earth. Most parts of the space station are expected to burn up high in the atmosphere but remaining debris could fall into the ocean. And the crash will likely happen in the years 2017.

Tiangong-1 is not functioning anymore but it will be tracked by the radar network operated by U.S. Department of Defense. So, researchers will be able to say when and where it will fall to Earth.

NASA’s Hubble Telescope Finds a Planet Orbiting Two Stars

Astronomers have recently confirmed the presence of a distant star orbiting around twin stars.

The system, called OGLE-2007-BLG-349, is located 8,000 light years away from Earth while the planet in the system orbits twin stars roughly at the distance of 300 million miles away. It takes around seven years for the planet to complete an orbit around both the stars.The twin stars are red dwarfs and are 7 million miles apart, which is a relatively small distance in astronomical terms.

The system was originally discovered in 2007 but ground-based observations only able to uncover a single star and a planet at that time. Further analysis revealed a third body in the system.

Water Bear Protein could Protect Human DNA from Radiation 

Scientists have just discovered the secret behind the durability of world’s hardest animal and they believe its protein could protect human DNA from extreme radiation.

The miniscule water bear is considered the most indestructible animal on Earth and its durability has long fascinated scientists. The organism can withstand extreme conditions better than any other creature. Even the microgravity conditions of outer space cannot break it. 

In the latest experiments with human cells, researchers have found that water bear’s protein dubbed "Dsup" could work as a shield to protect human DNA especially from harmful radiations.

Scientists Solve the Mystery of Singing Fish  

Fish can also sing like humans. In 1980s, people living on houseboats in San Francisco used to hear a mysterious humming at night. Now a study reveals that the mysterious hum came from male plainfin midshipman fish that sing at night to attract mates and it’s a biological clock called melatonin that ensures that the fish will only sing at night and stop in the morning. 

Plainfin midshipman could grow up to 15 inches in length and swim along the coast of Pacific Ocean in California.
