Aquatic Environment Biodiversity Threatened by Pesticides
June 18, 2013 03:09 PM - Allison Winter, ENN

The use of pesticides have been debated for some time now, as research indicates their use can have a negative effect on the environment. As an agent meant to prevent, destroy or mitigate any pest, pesticides target unwanted plants and animals that can alter ecosystems, cause nuisance, or spread disease. Besides potentially being toxic to humans and other animals, new research conducted by an international team of scientists has revealed that pesticides are responsible for reducing regional biodiversity of invertebrates by up to 42 percent.

Titan's Haze
June 7, 2013 02:40 PM - Andy Soos, ENN

Haze in the air means that is not clear and that it is dimmer as a result. Light is blocked. Welcome to Titan whose haze would make the worst day in an earth city clear as a bell. Scientists working with data from NASA's Cassini mission have confirmed the presence of a population of complex hydrocarbons in the upper atmosphere of Saturn's largest moon, Titan, that later evolve into the components that give the moon a distinctive orange-brown haze. The presence of these complex, ringed hydrocarbons, known as polycyclic aromatic hydrocarbons (PAHs), explains the origin of the aerosol particles found in the lowest haze layer that blankets Titan's surface. Scientists think these PAH compounds aggregate into larger particles as they drift downward.

SPOTLIGHT

The Tesla Model S

ERIC NIILER, DiscoveryNews
The new all-electric Tesla S sedan is not just the favorite of car magazines, now Consumer Reports calls it the best car they’ve ever driven, scoring 99 points of 100 and beating out the Lexus LS460 that held the previous record back in 2007. What does this massive battery-powered EV have that no others do? "It handles like a sports car, it rides like a luxury car, it has the energy efficiency that is twice as good as the best hybrids and is the quietest car we’ve ever tested," said CR tester Gabe Shenhar. "It does so many things so right on so many levels that to us it wasn't a surprise." Perhaps that's why Tesla Motors has sold more cars during the first quarter of 2013 than luxury German automakers, Mercedes-Benz, BMW and Audi, prompting the Palo Alto-based firm to declare its first-ever profit and raise expected sales for 2013 from 20,000 to 21,000.

Last night I took a drive to Sunset Park, only to find it silent. For the last few weeks I had been taking regular trips to the park to track the progress of the Brood II Cicadas that everyone seems to be talking about. They are silent at night, the only proof of their existence [...]

Green Life After Death

June 3rd, 2013
Western burial traditions have been known to not be the most eco friendly. Practices like burying coffins in concrete vaults interrupt the natural process of decomposition and embalming bodies in formaldehyde introduces hazardous toxins to the environment. Fortunately, over the last few years, there has been a change in attitude, with more and more people opting for more green options.

Pizza from the Printer?

May 23rd, 2013
When I first read about NASA’s $125,000 grant to Systems and Materials Research Corporation to create a 3-D food printer, I was excited, confused, and a little weirded out. A range of thoughts and questions ran through my mind. What would the food be made out of? Would it taste and feel like real food, [...]
