Electricity from silk cocoons?

Researchers in India say they have developed a prototype of an energy-harvesting device from the cocoons of a domesticated species of silk moth. They hope to put the technology to practical use while also tackling waste materials from the silk processing industry.

How did sea life end up living in outer space?

Russian astronauts, or cosmonauts, have discovered living organisms clinging to the exterior of their International Space Station. The microscopic creatures were discovered during a space walk to clean the surface of the vessel, and they’ve reportedly been identified as a type of sea plankton. But scientists have no idea how they got there.

Drought Causes Western US to Rise

Climate Change News - ENN - August 22, 2014 - 3:00pm
Severe drought affecting the western United States in recent years is not only influencing water restrictions for residence and creating problems for crops and wildlife, but it's changing the landscape by causing land to rise up in elevation.

Fracking's Chemical Cocktails

Fracking is once again in trouble. Scientists have found that what gets pumped into hydrocarbon-rich rock as part of the hydraulic fracture technique to release gas and oil trapped in underground reservoirs may not be entirely healthy. Environmental engineer William Stringfellow and colleagues at Lawrence Berkeley National Laboratory and the University of the Pacific told the American Chemical Society meeting in San Francisco that they scoured databases and reports to compile a list of the chemicals commonly used in fracking.

ACC Testifies at Louisiana Field Briefing on EPA Ozone Regulations

Michael Walls warned that dramatically lower ozone NAAQS would jeopardize U.S. manufacturing expansion, urged EPA to fully implement current standard.

How does CO2 go from Permafrost into the atmosphere?

Climate Change News - ENN - August 21, 2014 - 4:41pm
The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide (CO2) after entering the freshwater system in a process thought to be controlled largely by microbial activity. However, a new study – funded by the National Science Foundation and published this week in the journal Science – concludes that sunlight and not bacteria is the key to triggering the production of CO2 from material released by Arctic soils.

Study shows sunlight, not microbes dominate CO2 production in Arctic

Climate Change News - ENN - August 21, 2014 - 4:38pm
Just how much Arctic permafrost will thaw in the future and how fast heat-trapping carbon dioxide will be released from those warming soils is a topic of lively debate among climate scientists. To answer those questions, scientists need to understand the mechanisms that control the conversion of organic soil carbon into carbon dioxide gas. Until now, researchers believed that bacteria were largely responsible.

NASA reports unknown source of banned ozone-destroying compound

NASA research has revealed the Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide. Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012.

Turning Jellyfish into Sustainable Medical Products

In a United Nations report released in May, scientists worldwide were called upon to join the war on jellyfish. According to the report, jellyfish have overwhelmed the marine ecosystem as a result of the overfishing of more competitive species, consuming fish eggs and larvae of weaker specimens and creating what the report called a "vicious cycle." So how can this cycle be stopped?

New Satellite To Help Farmers Facing Drought

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

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.

Plant Language

A Virginia Tech scientist has discovered a potentially new form of plant communication, one that allows them to share an extraordinary amount of genetic information with one another. The finding by Jim Westwood, a professor of plant pathology, physiology, and weed science in the College of Agriculture and Life Sciences, throws open the door to a new arena of science that explores how plants communicate with each other on a molecular level. It also gives scientists new insight into ways to fight parasitic weeds that wreak havoc on food crops in some of the poorest parts of the world.

Harnessing High-Altitude Wind Energy

Climate Change News - ENN - August 14, 2014 - 8:53am
Researchers have discovered that the world's energy needs could easily be met by harnessing the power potential of high-altitude winds. Developers in an emerging field known as airborne wind energy envisage using devices that might look like parachutes or gliders to capture electricity from the strong, steady winds that blow well above the surface in certain regions.

Engineering Fruit Flies May Help Crops

We've genetically-modified crops to enhance desired traits such as increased resistance to herbicides or pesticides. Nonetheless, pests still infest crops around the world. In an attempt to control these pests, scientists have turned to genetically engineering the pests themselves!

The cost of marine debris

Regulatory news - ENN - August 12, 2014 - 4:53pm
Marine debris has many impacts on the ocean, wildlife, and coastal communities. A NOAA Marine Debris Program economic study released today shows that it can also have considerable economic costs to residents who use their local beaches. The study found that Orange County, California residents lose millions of dollars each year avoiding littered, local beaches in favor of choosing cleaner beaches that are farther away and may cost more to reach. Reducing marine debris even by 25 percent at beaches in and near Orange County could save residents roughly $32 million during three months in the summer.

Bottling Water from Drought Stricken Areas

Climate Change News - ENN - August 12, 2014 - 8:55am
The bottled water industry has grown exponentially the past few decades despite the fact tap water in the United States is generally safe. Never mind the fact bottled water producers have had more than their fair share of safety issues: bottled water has become accepted by consumers. While companies such as Nestlé insist they are taking responsibility for water stewardship and recycling, they also bottle their water at dubious sources, including those in drought stricken regions.
