• This breakthrough turns old tech into pure gold — No mercury, no cyanide, just light and salt
  At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool disinfectants and a novel polymer that can be reused, the method avoids toxic chemicals like mercury and cyanide. It even works on […]
• Self-lighting chip uses quantum tunneling to spot a trillionth of a gram
  Imagine detecting a single trillionth of a gram of a molecule—like an amino acid—using just electricity and a chip smaller than your fingernail. That’s the power of a new quantum-enabled biosensor developed at EPFL. Ditching bulky lasers, it taps into the strange world of quantum tunneling, where electrons sneak through barriers and release light in […]
• Scientists freeze quantum motion using ultrafast laser trick
  Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control them using pure electronic tricks and laser precision.
• Researchers develop recyclable, healable electronics
  Electronics often get thrown away after use because recycling them requires extensive work for little payoff. Researchers have now found a way to change the game.
• Ultra-thin lenses that make infrared light visible
  Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.
• Engineers develop self-healing muscle for robots
  Students recently unveiled their invention of a robotic actuator -- the 'muscle' that converts energy into a robot's physical movement -- that has the ability to detect punctures or pressure, heal the injury and repair its damage-detecting 'skin.'
