Clues found In Crater Left By Dinosaur-Killing Asteroid
May 6, 2016 09:38 AM - GEOFF BRUMFIEL,NPR

Scientists have had a literal breakthrough off the coast of Mexico.

After weeks of drilling from an offshore platform in the Gulf of Mexico, they have reached rocks left over from the day the Earth was hit by a killer asteroid.

The cataclysm is believed to have wiped out the dinosaurs. "This was probably the most important event in the last 100 million years," says Joanna Morgan, a geophysicist at Imperial College in London and a leader of the expedition.

Since the 1980s, researchers have known about the impact site, located near the present-day Yucatan Peninsula. Known as Chicxulub, the crater is approximately 125 miles across. It was created when an asteroid the size of Staten Island, N.Y., struck the Earth around 66 million years ago. The initial explosion from the impact would have made a nuclear bomb look like a firecracker. The searing heat started wildfires many hundreds of miles away.

Is your home making you sick?
April 20, 2016 06:40 AM - University of Surrey

New research in the journal Science of the Total Environment has highlighted the dangerous effects of indoor pollution on human health, and has called for policies to ensure closer monitoring of air quality.

A collaborative effort of European, Australian and UK researchers, led by the University of Surrey,  assessed the harmful effects of indoor pollution in order to make recommendations on how best to monitor and negate these outcomes.

Dr Prashant Kumar of the University of Surrey explained, “When we think of the term ‘air pollution’ we tend to think of car exhausts or factory fumes expelling grey smoke. However, there are actually various sources of pollution that have a negative effect on air quality, many of which are found inside our homes and offices. From cooking residue to paints, varnishes and fungal spores the air we breathe indoors is often more polluted than that outside.”

Educating Consumers About Buying Sustainably

Gina-Marie Cheeseman , Triple Pundit

Sustainability is a word tossed around much these days. But do consumers really care about buying sustainably? The answer is yes. More and more consumers are interested in sustainability, as surveys show.  A 2011 consumer survey by Nielsen found that 66 percent of socially-conscious consumers cited environmental sustainability as the most important issue from a list of 18 issues.

So, how do you increase awareness of buying sustainably among consumers? The key is getting information to them. A study by Michigan State University researchers, published in 2014 in the Business and Economics Journal, looked at consumer awareness of fair trade information. The researchers found that informed consumers “are better positioned to make sound decisions and take the appropriate actions to address sustainability issues.” Providing access to “complete and accurate sources of information allows consumers to draw the connection between their consumption behaviors and social, and environmental sustainability,” the researchers concluded.
