  • High reaction rates even without precious metals
    Non-precious metal nanoparticles could one day replace expensive catalysts for hydrogen production. However, it is often difficult to determine what reaction rates they can achieve, especially when it comes to oxide particles. This is because the particles must be attached to the electrode using a binder and conductive additives, which distort the results. With the aid of electrochemical analyses of individual particles, researchers have now succeeded in determining the activity and substance conversion of nanocatalysts made from cobalt iron oxide -- without any binders.

  • 'Goldilocks' neurons promote REM sleep
    It has been a mystery why REM sleep, or dream sleep, increases when the room temperature is 'just right'. Neuroscientists show that melanin-concentrating hormone neurons within the hypothalamus increase REM sleep when the need for body temperature defense is minimized, such as when sleeping in a warm and comfortable room temperature. These data have important implications for the function of REM sleep.
  • Fatty fish without environmental pollutants protect against type 2 diabetes
    If the fatty fish we eat were free of environmental pollutants, it would reduce our risk of developing type 2 diabetes. However, the pollutants in the fish have the opposite effect and appears to eliminate the protective effect from fatty fish intake. This has been shown by researchers using innovative methods that could be used to address several questions about food and health in future studies.
