Disc or Download: A Virtual Energy-Savings Debate
September 11, 2014 11:20 AM - Winfield Winter, ENN
One of the best ways to spark an energy revolution is through the younger generation — and nothing quite speaks their language like video games. But this issue has less to do with the content of these addictive games and more with how the younger generation consumes them. Fantasy and adventure, sci-fi and first-person shooters, strategy and racing — video games today comes in all types of genres with thousands of add-ons and customizable features to make each story a virtual reality. And with all of these choices comes two more: buy a copy of the video game on a disc or download the video game straight from the console?
How is a warming climate impacting coral reefs?
September 10, 2014 07:34 AM - Roger Greenway, ENN
How is a warming climate impacting life in the oceans? Fish can move to cooler areas, but coral reefs are anchored in place. Late-summer water temperatures near the Florida Keys were warmer by nearly 2 degrees Fahrenheit in the last several decades compared to a century earlier, according to a new study by the U.S. Geological Survey. Researchers indicate that the warmer water temperatures are stressing corals and increasing the number of bleaching events, where corals become white resulting from a loss of their symbiotic algae. The corals can starve to death if the condition is prolonged.
How Pollutant Risk is Affected by Different Insect Stages
September 5, 2014 11:34 AM - Editor, ENN
The food chain is a hierarchical series of organisms that are interrelated in their feeding habits. The chain starts when the smallest being like an insect is fed upon a larger prey species, which in turn feeds an even larger species. So if a species among the lower ranks of the chain has accumulated toxins such as pesticides or other organic chemicals, there is potential for these toxic substances to affect the species that prey upon them. This is the subject of new research conducted by the US Geological survey that found when fish feed on insects and when other wildlife species feed on fish, harmful contaminants are transferred up the line.
More benefits of green neighborhoods
September 4, 2014 02:32 PM - Oregon State Universtity
Mothers who live in neighborhoods with plenty of grass, trees or other green vegetation are more likely to deliver at full term and their babies are born at higher weights, compared to mothers who live in urban areas that aren’t as green, a new study shows. The findings held up even when results were adjusted for factors such as neighborhood income, exposure to air pollution, noise, and neighborhood walkability, according to researchers at Oregon State University and the University of British Columbia.
Mystery Behind Slithering Rocks of Death Valley Revealed
August 28, 2014 09:38 AM - Allison Winter, ENN
In California's Death Valley, a geological phenomenon exists. Sailing stones, or moving rocks can be observed on the valley floor inscribing long trails on the ground without human or animal intervention. For over 60 years of observations, no one has been able to uncover the mystery of what is actually pushing these stones across the sand. That is, until now.
Yawn Contagion in Wolves
August 27, 2014 04:15 PM - Editor, ENN
A yawn is defined as a reflex act of opening one's mouth and inhaling deeply. We yawn most often when we are tired or when we're bored. But we also always yawn when we see someone else doing it. Why? People say we can't help it - it's contagious! But what really triggers this involuntary tendency? According to studies, yawning when others do is a sign of empathy and a form of social bonding. And believe it or not, we're not the only species to exhibit these contagious behaviors. A new study published today in the journal PLOS ONE shows that wolves may also be susceptible to yawn contagion.
Africa Faces Unsustainable Levels of Ivory Poaching
August 20, 2014 06:27 AM - Allison Winter, ENN
When it comes to illegal wildlife trade, one thing has always puzzled me ... Why is the demand for ivory so high? While I may not come across the black-market demands or understand the cultural or historical needs for these rare animal teeth, one thing is easy to see - populations of the African elephant are declining.
New Satellite To Help Farmers Facing Drought
August 19, 2014 09:08 AM - Allison Winter, ENN
Satellites are put into orbit for a variety of tasks. From sending television signals to our homes to enabling GPS devices, to helping us see weather on a global scale, satellites collect information and provide us with modern conveniences. One new use for a proposed satellite scheduled to launch this winter is soil moisture monitoring at a local level.
Origami in Space
August 16, 2014 09:30 AM - Winfield Winter, ENN
An ancient art form is beginning to take off in a way no one thought possible: on a spaceship. Origami, or Japanese folding paper, is currently being developed into solar panels at NASA's Jet Propulsion Laboratory at The California Institute of Technology. Solar panels that have endless applications. Space travel has already turned over the possibility of solar-powered flight via folding panels, but this particular reincarnation is different. Developers cite a more intricate fold that allows for efficient deployment of the solar arrays. And it doesn’t stop there. Origami may one day be used in self-assembling solar arrays that are launched into space to power the earth below.
Marine noise impacts eels too!
August 7, 2014 08:45 AM - Roger Greenway, ENN
Marine noise has been studied for it's impact on whales, dolphins and other marine animals. Might it also impact smaller creatures too? Eels, for example. Despite their reputation as slippery customers, a new study has shown that eels are losing the fight to survive when faced with marine noise pollution such as that of passing ships. Scientists from the Universities of Exeter and Bristol found that fish exposed to playback of ship noise lose crucial responses to predator threats. The study, published today in the journal Global Change Biology, found European eels were 50 per cent less likely to respond to an ambush from a predator, while those that did had 25 per cent slower reaction times. Those that were pursued by a predator were caught more than twice as quickly when exposed to the noise.
