Imagine reading by the light of an exploded star, brighter than a full moon – it might be fun to think about, but this scene is the prelude to a disaster when the radiation devastates life as we know it...

The findings by Oregon State University researchers were published in the journal Nutrients.

The research by scientists at OSU’s Linus Pauling Institute involved 42 healthy people ages 55 to 75 and was designed to measure the supplement’s effects on certain immune system indicators. It also looked at bloodstream levels of zinc and vitamins C and D while taking the supplement, as these micronutrients are important for proper immune function.

The immune indicators, including white blood cells’ ability to kill incoming pathogens, ...

Chilled panels use half the energy of conventional air conditioners and can be used outdoors or indoors. AC’s guzzle power and spew out millions of tons of carbon dioxide daily. They’re also not always good for your health – constant exposure to central A/C can increase risks of recirculating germs and causing breathing problems.

There’s a better alternative, say a team of researchers from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre.

They call it the Cold Tube, and they have shown it works.
“Air conditioners work by cooling down and dehumidifying the air around us – an expensive and not particularly environmentally friendly proposit...
