A team of researchers has analyzed what little activity exists around the black hole at the center of our galaxy. By studying 3 million seconds of observations taken by the Chandra X-Ray Observatory, the team found that much of the nearby radiation comes from material that is ejected before reaching the black hole, with very little energy arising from the black hole itself.
In a fun, exciting talk, teenager Henry Lin looks at something unexpected in the sky: distant galaxy clusters. By studying the properties of the universe's largest pieces, says the Intel Science Fair award winner, we can learn quite a lot about scientific mysteries in our own world and galaxy.
Inspired by termites and their building activities, the TERMES project is working toward developing a swarm construction system in which robots cooperate to build 3D structures much larger than themselves.
Artificial intelligence is an ever evolving goal for researchers, and the object of endless fascination for writers, filmmakers, and the general public. But despite our best science fiction visions, creating digital intelligence is incredibly difficult.
