On Saturday, China began building what is expected to be the world's largest dam. The dam, which is in Tibet, will produce massive amounts of electricity. But it has upset people in India and Bangladesh, who are worried about how the dam will affect them.
Scientists at Loughborough University in the United Kingdom have created what they call "the world's smallest violin". The violin is made of metal and is so tiny that it can only be seen with a powerful microscope. The project was designed to test new technology for building extremely small things.
Scientists studying a black "goo" found on a research ship in the Great Lakes have learned that the goo wasn't just unusual - it actually contained a life form never heard of before. The slime still has scientists puzzling over several mysteries.
Librarians at Harvard Law School have learned that they own an original version of one of the world's most important documents – the Magna Carta.

Scientists have made a surprising discovery about one of Australia's migrating moths - Bogong moths use the stars to help guide them on their long trips across Australia. The moths are the first insects known to use the stars as a guide while migrating.
Students at Purdue University have created a robot that can solve a Rubik's Cube faster than any robot ever. The robot, which they call "Purdubik's Cube", solves the cube in just 0.103 seconds. That's faster than the time it takes to blink your eyes.
On Monday, scientists released the first pictures taken by the Vera C. Rubin Observatory in Chile.
