Shifting bird and reptile distributions
April 8, 2014 12:23 PM - Robin Blackstone, ENN
With climate change come several dramatic shifts in species distribution within the United States. The U.S. Geological Survey in concert with the University of New Mexico and Northern Arizona University have recently projected distribution losses for nearly half of the 5 examined reptile species including the locally famed chuckwalla. Breeding bird ranges, however exhibited broader expansions and contractions within their breeding habitats.
Why Are Scientists Genetically Modifying Trees?
April 7, 2014 10:41 AM - Kevin Mathews, Care2
The Lorax may speak for the trees, but even he might want to stop to listen to researchers' new plans to genetically alter trees. What may outwardly seem like disconcerting news just might change how paper is made for the better. The engineered trees would allow manufacturers to create paper significantly easier. Moreover, it's not just the paper industry that benefits from this change — the effects would be advantageous to the entire planet.
Desert absorption helps curtail CO2 levels
April 7, 2014 09:55 AM - Eric Sorensen, Washington State University News
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget — how much carbon remains in the atmosphere as CO2, contributing to global warming, and how much gets stored in the land or ocean in other carbon-containing forms.
Smog alerts for Europe
April 4, 2014 04:21 PM - Rob MacKenzie, The Ecologist
The UK news media has been buzzing with reports of air pollution alerts associated, at least in part, with the long-range transport of dust from the Sahara. Colleagues from Africa have asked why we in the UK are worried about the health effects of a relatively rare occurrence of this long-range dust all the way across Europe, when African countries experience dust storms of much higher intensity almost daily at some times of year.
Unearthing of large tusk in Arabian Desert suggests once greener pastures
April 4, 2014 09:49 AM - ENN Staff
Working in conjunction with the Saudi Commission for Tourism and Antiquities, researchers from the University of Oxford have discovered two pieces of a tusk that when combined measure six feet in length. The researchers believe it is from a Palaeoloxodon or a "straight tusked elephant". An elephant's carpal bone was recovered in a separate study done by a Swiss team in the Nefud Desert just five meters away. The sand layer dates back to approximately 325,000 years and the elephant is believed to be of the same age.
European Union Gets 23.4% of Electricity From Renewables
April 4, 2014 08:03 AM - Edouard Stenger, Clean Techies
According to official statistics from Eurobserv’ER, 23.4 percent of the electricity in the European Union came from renewable energy sources in 2012. The total output for 2012 has been estimated at 763.5 TW. This represents an important increase from 2011, when these energy sources brought "only" 20.4 percent of total electricity.

Climate change has been a constant reality for many Filipinos, with impacts ranging from extreme weather events to periodic droughts and food scarcity. The most affected populations are coastal residents and rural communities that lack proper disaster preparedness.
Crib mattresses expose infants to harmful emissions
April 2, 2014 03:30 PM - ENN Staff
University of Texas at Austin's Cockrell School of Engineering has found that crib mattresses expose sleeping infants to high levels of chemical emissions. Specifically, the team analyzed the foam padding from crib mattresses and found that the mattresses release significant amounts of volatile organic compounds (VOCs) which are potentially harmful chemicals found in many household items including cleaners and scented sprays.
American's energy usage jumps in 2013
April 2, 2014 01:08 PM - ENN Staff
Despite many individual efforts to decrease energy usage for 2013 increased by 2.3 Quadrillion thermal units over the previous year. These statistics have been monitored and presented by the Lawrence Livermore National Laboratory (LLNL) in the most recent energy flow charts measuring renewable, fossil and even nuclear energy.
Can Technology End Overfishing?
April 2, 2014 07:57 AM - Alexis Petru, Triple Pundit
Back in 2002, Thomas Kraft, managing director of Norpac Fisheries Export, came up with the idea to electronically track each fish the company captures and sells. Soon after Norpac's electronic monitoring system was up and running two years later, Kraft realized that the technology was not only an effective management tool, but it could also help the company trace fish through the supply chain and guarantee its products were not caught using illegal, unreported and unregulated (IUU) fishing practices.
