    Hundreds of galaxies seen in a new 3-D view of the universe

    The Hubble Space Telescope has some competition. A telescope in Chile has captured a three-dimensional view of a part of the sky previously imaged by Hubble. The image stretches across cosmic time, revealing modern day galaxies as well as ones seen as they existed when the universe was less than a billion years old. A single observation from a new high-tech camera on the telescope captured not...

    Brain cells predict opponent’s move in game-playing monkeys

    Newly discovered brain cells in monkeys can predict another monkey’s actions in a cooperation game. If such brain cells also exist in humans, they may be important in social interactions that require calculating another person’s intentions.The brain cells were found in rhesus macaques playing a video game called the prisoner’s dilemma. The cells keep track of how other monkeys behaved in previous...
