It’s estimated that we live in a world saturated with over 80,000 man-made chemicals.  They’re in pharmaceuticals, Continue reading

Nanoparticles Damage Healthy Soil Bacteria

Though some might argue that nanotechnology offers benefits not afforded by normal molecules, the environmental and human health consequences of this “breakthrough” technology appear dire, to say the least. New research published in the Journal of Hazardous Materials explains that nanoparticles damage beneficial soil bacteria and ultimately ruin plants’ ability to uptake necessary nitrogen.

Researchers Niraj Kumar and Virginia Walker from Queen’s University in Canada set out to investigate the effects of nanoparticles in the environment, comparing soil from the Arctic — which they believed would be the least contaminated with nanoparticles — to soil that was deliberately contaminated with various nanoparticles, including silver nanoparticles.

Some Colors Offer Better Sun Protection

Some Colors Offer Better Sun Protection

Do you want to protect your body from the sun’s harmful rays, but don’t want to pay premium prices for clothes made from high-tech fabrics that promise to protect from damaging UV rays? Think blue and red rather than yellow. Spanish scientists have found that cotton fabrics dyed deep blue or red provide better UV protection than the same fabric dyed yellow.

The researchers found that the color of a fabric is one of the most important factors in how well clothes protect against ultraviolent radiation, although scientists aren’t sure exactly how color interacts with other factors to affect protection.

Clothing dyed a shade of deep blue provided the most protection while yellow afforded the least.
