By mixing polymer powder in solution to generate a film that they then stretched, MIT researchers have changed polyethylene’s microstructure, from spaghetti-like clumps of molecular chains (left), to straighter strands (right), allowing heat to conduct through the polymer, better than most metals.

MIT Scientists Develop Polyethylene with Better Heat Conducting Properties than Ceramics

Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitt, or a Styrofoam coffee cup, both manufactured from polymer materials that are excellent at trapping heat. Now MIT engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat — an ability normally associated with metals. In experiments, they found the films, which are thinner than plastic wrap, conduct heat better than ceramics and many metals, including steel.

Red Phosphor Improves Luminescence of LED Lights

The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.

You can't fool dogs, they say. They always see through us. But do they really understand our intentions? A team of researchers has now investigated this question on the basis of behavioral studies. (Public Domain)

Unable or Unwilling? How Dogs Read Your Intentions

Although every dog owner thinks their dog is special and understands them, dogs in general have developed a range of skills for bonding with human beings during the long time they have been evolving alongside us. But whether dogs understand human intentions, or merely respond to outcomes, remains unclear. A recent study found that dogs can differentiate between intentional and unintentional acts.
