The magnetic field of Uranus flips on and off like a switch: Study based on data collected by NASA’s Voyager

Scientists have found that Uranus magnetic field gets flipped on and off like a light switch every day as the planet rotates. Researchers from Georgia Institute of Technology in the US made the discovery based on the data from NASA’s Voyager 2 spacecraft that sped past Uranus in 1986. “The magnetosphere is open in one orientation, allowing solar wind to flow into the magnetosphere; it later closes, forming a shield against the solar wind and deflecting it away from the planet,” researchers said. This is much different from Earths magnetosphere,…

Researchers build simple DNA machines that can be used for making molecular computers

Scientists have built simple machines out of DNA, which switch reversibly between two different shapes and could be used to make nanotech sensors, amplifiers and even a molecular computer. The DNA machines can relay discrete bits of information through space or amplify a signal, said Yonggang Ke, an assistant professor from Georgia Institute of Technology in the US. “In the field of DNA-based computing, the DNA contains the information, but the molecules are floating around in solution,” Ke said. “Whats new here is that we are linking the parts together…

Georgia Tech survey shows most selfies on Instagram are for flaunting appearance

More than half of selfies on Instagram are posted to show off a persons appearance, including make-up and clothes, scientists say. Researchers from Georgia Institute of Technology in the US combed through selfie posts on photo-sharing social platform Instagram to determine what kinds of identity statements people make by taking selfies. They gathered the data by searching for hashtag #selfie, and then used computer vision to confirm that the pictures actually included faces. Researchers found nearly 52 per cent of all selfies fell into the appearance category: pictures of people…
