  • Perovskite solar cells bring flexibility and lower cost

    Solar cells are often heralded as the future in renewable energy technology, but have been hindered by their inflexible composition and high costs. In recent years, researchers have been developing improved solar cells using perovskite, a mineral composed primarily of calcium titanate. A new report published in Science from scientists at the Georgia Institute of Technology, University of Califor...

  • Robot arm learns physical skills by playing Jenga

    For decades, engineers and computer programmers have been teaching robots how to play popular games like chess and Go. Artificial intelligence has even claimed the global top spot in some of these games, like when Google DeepMind’s AlphaGo software defeated Go world champion Lee Sedol nearly three years ago. Now, researchers at the Massachusetts Institute of Technology are training a robot to play...

  • Ice melting 4x faster than expected

    For some time, scientists have worried about the rapidly rising sea level of the world’s oceans. It was believed that the main contributor to this increase was glaciers in southeast and northwest Greenland releasing large chunks of ice into the Atlantic Ocean. Now, a study published in the Proceedings of the National Academy of Sciences...

  • Earth's water may have come from the Sun

    Scientists have been attempting to decipher the origin of water on Earth for decades. A new study in the Journal of Geophysical Research: Planets of the American Geophysical Union puts forward a new theory towards resolving this mystery, suggesting that the hydrogen in Earth’s water originated from clouds of dust and gas remaining after the formation of the Sun.
