(Sheffield University) Scientists have discovered maize crops emit chemical signals to attract growth promoting microbes to their roots, which boosts performance and could combat world food shortages.
The groundbreaking research – the first chemical signal that has been shown to attract the beneficial bacteria – could reduce agricultural reliance on fertilisers and pesticides across the globe.
Researchers from the University of Sheffield and Rothamsted Research in Hertfordshire, who collaborated on the Biotechnology and Biological Sciences Research Council (BBSRC) funded project, discovered that maize crops emit chemical signals which attract growth-promoting microbes to live amongst their roots.
Dr Andrew Neal, who co-led the research, said: “We have known for a while that certain plants exude chemicals from their roots that attract other organisms to the area. In fact, the environment around a plant´s roots teems with microorganisms and populations of bacterial cells can be up to 100 times denser around roots than elsewhere.
By Walter Brasch (Moronia) There’s nothing to suggest that in his 51 years Kevin June should be a leader.
Not from his high school where he dropped out after his freshman year.
Not from his job, where he worked as an auto body technician for more than 35 years.
Both of his marriages ended in divorce, but did produce two children, a 31-year-old son and a 28-year-old daughter.
June readily admits that for most of his life, beginning about 14 when he began drinking heavily, he was a drunk. Always beer. Almost always to excess. But, he will quickly tell you how many weeks he has been sober. It’s now 56, he says proudly.
In October 2008 he was in an auto accident, when he swerved to miss a deer and hit an oak tree head on. That’s when he learned MRIs showed he had been suffering from degenerative arthritis. Between the accident and the arthritis, he was off work for three months. Then, in May 2009, he was laid off when the company moved.
The pain is now so severe that after about 10 minutes, he has to sit.
Unable to work, surviving on disability income that brings him $1,300 a month, just $392.50 above the poverty line, he lives in the 12-acre Riverdale Mobile Home Village, along the Susquehanna River near Jersey Shore in north-central Pennsylvania. The village has a large green area where families can picnic, relax, or play games, sharing the space with geese and all kinds of animals.
For most of the six years June lived in the village, he kept to himself—chatting with neighbors now and then, but nothing that would ever suggest he’d be a leader. The last time he led anything was almost two decades earlier when he was president of a 4-wheel club.
On Feb. 18, the residents found out their landlord had sold the park, only after reading a story in the Williamsport Sun-Gazette. The landlord, who the residents say did what he could to make their village safe and attractive, later came to each of the 37 families. He told the families he sold the park and they would have two months to leave. It was abrupt. Business-like. “We knew he was planning to sell,” says June, “but we all thought it would be to someone who would allow us to stay.”
Four days after the residents were ordered to move, certified letters made it official. The owner sold the park to Aqua PVR, a division of Aqua America, headquartered in Bryn Mawr. Sale price was $550,000. It may have been a bargain—land and industrial parks that have been vacant for years are going for premium sales prices as the natural gas boom in the Marcellus Shale consumes a large part of Pennsylvania and four surrounding states.
Aqua had received permission from the Susquehanna River Basin Commission (SRBC) to withdraw three million gallons of water a day from the Susquehanna; the 37 families of the mobile home village would just be in the way. The company intends to build a pump station and create a pipe system to provide water to natural gas companies that use hydraulic fracturing, the preferred method to extract natural gas from as deep as 10,000 feet beneath the earth. The process, known as fracking, requires a mixture of sand, chemicals, many of them toxins, and anywhere from one to nine million gallons of water per well, injected into the earth at high pressure. Jersey Shore sits in a northeastern part of the Marcellus Shale, which is believed to hold about 500 trillion cubic feet of natural gas.
Aqua isn’t the only company planning to take water in the area. Anadarko E & P Co. and Range Resources-Appalachia have each applied to withdraw up to three million gallons a day from the Susquehanna. While the Delaware River Basic Commission, and the states of New York and Maryland, have imposed moratoriums upon the use of fracking until full health and environmental impacts can be assessed, Pennsylvania and the SRBC have been handing out permits by the gross.
Most residents had only a vague knowledge of fracking and what it is doing to the earth. “They have a lot more knowledge now,” says June, as politically aware as any environmentalist.
Aqua had originally ordered the residents to leave by May 1, but then extended it to the end of the month. It dangled a $2,500 relocation allowance in its eviction.
However, the cost to move a trailer to another park is $6,000–$11,000, plus extra for skirting, sheds, and any handicap-accessible external ramps. But, most trailers can’t be moved. “These are older trailers,” says June. His is a 12-by-70, built in 1974, with a tin roof and tin siding (“tin-on-tin”); like others, it isn’t sturdy enough to survive a move. But even if it did, there would be no place to put it. The parks want the newer trailers, but most parks are full.
So, the residents began looking in the classified ads for rentals. Because the natural gas companies are bringing in thousands of employees to frack the land, there is a shortage of apartments, most with inflated prices to take advantage of the well-paid roustabouts, drivers, and technicians who moved into the area, and spend their money on local businesses eager to improve their own profits. During the past two years, rents have doubled and tripled. “None of us can pay a thousand or more a month,” says June. The current mobile home owners paid $200 a month for their lot.
Not long after he was served his own eviction notice, June had a dream. Some might call it a nightmare; some might see it as he did, a religious experience. “It was Jesus coming to me, telling me I had to do something,” he says.
June is constantly on the move, going from trailer to trailer to help the families who were abruptly evicted. Whatever their needs, Kevin June tries to provide it, constantly on the phone, running up phone bills he knows he can’t afford but does so anyhow because the lives of his neighbors matter.
There’s Betty and William Whyne. Betty, 82, began working as a waitress at the age of 13 and now, in retirement, makes artificial Christmas trees. She has a cancerous tumor in the same place where a breast was removed in 1991. William, 72, who was an electrician, carpenter, and plumber before he retired after a heart attack, goes to a dialysis center three times a week, four hours each time. They brought their 12-wide 1965 Fleetwoood trailer to the village shortly after the 1972 flood. Like the other residents, they can’t afford to move; they can’t find adequate housing. “We’ve looked at everything in about a 30 mile radius,” they say. They earn $1,478 a month from retirement, only $252.17 above the federal poverty line. One son is in New Jersey; one is in Texas, and the Whynes don’t want to leave the area; they shouldn’t have to.
There’s April and Eric Daniels. She’s a stay-at-home mom for their two children; he’s a truck driver whose hours have been reduced. Their 14-by-70 trailer is valued at $13,200; she and her husband were in the process of remodeling it, had already paid $5,000 for improvements, and were about to start building a second bathroom. April Daniels had grown up living in a series of foster houses, “so I know what it’s like to move around, but this was my first home, and it’s harder for me to leave.” Their trailer provides a good home, but can’t be moved. “We’re pretty much on the verge of just tearing down the trailer and living in a camper,” she says. They don’t know what will happen. They do know that because of what they see as Aqua’s insensitivity, they will lose a lot of money no matter what they do.
Doris Fravel, 82, a widow on a fixed income of $1,326 a month, has lived in the village 38 years. She’s proud of her 1974 12-wide trailer with the tin roof. “I painted it every year,” she says. In June, she paid $3,580 for a new air conditioner; she recently paid $3,000 for new insulated skirting. The trailer has new carpeting. Unlike most of the residents, she found housing—a $450 a month efficiency. But it’s far smaller than her current home. So she’s sold or given away most of what she owns. She may have a buyer for the trailer, and will take $2,500 for it, considerably less than it’s worth. “I can’t do anything else,” she says. “I just can’t move my furnishings into the new apartment,” she says. Like the other residents, she has family who are helping, but there’s only so much help any family can provide. “I never knew I would ever have to leave,” she says, but she does want to “see one of those gas men come to my door—and I’d like to punch him in the shoulder.”
Not only are there few lots available and apartments are too expensive, but most residents don’t qualify for a house mortgage; and there are waiting lists for senior citizen and low-income housing. The stories are the same.
No one from Aqua has been in touch with any resident. But, the company did hire a local real estate agency. The agency claims it has made extraordinary efforts to help the residents find other housing. The residents disagree. April Daniels says “some of the Realtors have gotten real nasty with the people in the park—they just don’t understand that we are all in a hardship, so we get mad and frustrated and take it out on them.” But there really isn’t much anyone can do. The natural gas boom has made affordable housing as obsolete as the anthracite coal that once drove the region’s energy economy.
The residents, with limited incomes, have lived good lives; they are good people. They paid their rents and fees on time; they kept up the appearances of their trailers and the land around it. They worked their jobs; they survived. Until they were evicted
And now it’s up to the residents to try to survive. They have become closer; they listen to each other; they hug each other; and, the tough men aren’t afraid to let others see them cry. “The pain in this park is almost too much at times,” says June.
If something goes wrong, the residents have to fix it; Kevin June is the one they call. If he can’t fix a problem, he finds someone who can. In this trailer park, as in most communities, there is a lot of talent—“we help each other,” says June. His job is to make sure the residents survive. I’ve had the Holy Spirit running through my veins a long time, but it’s running real deep right now,” he says.
A half-dozen families have already moved, but most say they will stay and fight what they see as a politically-based corporate takeover.
During the week Aqua PVR issued eviction notices, its parent company issued a news release, boasting that its revenue for 2011 was $712 million, a 4.2 percent increase from the year before; its net income was $143.1 million, up 15.4 percent from the previous year. But, for some reason, the company just couldn’t find enough money to give the residents a fair moving settlement. “They just expect us to throw our homes into the street and live in tents,” says June.
“I went to see a state representative to ask what he could do to help,” he says, “but his secretary just coldly told me there was nothing that could be done because whoever owns a property can do with it what he wants to do.” He never saw the state representative.
The Commonwealth of Pennsylvania—armed with an industry-favorable law recently rammed through by the Republican-controlled legislature and eagerly signed by a first-term Republican governor who received more than $1.6 million in campaign contributions from the energy industry—has decided that fracking the earth, threatening health and the environment, is far better for business than taking care of the people.
Kevin June and 36 families are just collateral damage.

By Giles Parkinson (Renew Economy) Deutsche Bank solar analyst Vishal Shah noted in a report last month that EPEX data was showing solar PV was cutting peak electricity prices by up to 40 per cent, a situation that utilities in Germany and elsewhere in Europe were finding intolerable. “With Germany adopting a drastic cut, we expect major utilities in other European countries to push for similar cuts as well,” Shah noted.
Analysts elsewhere said one quarter of Germany’s gas-fired capacity may be closed, because of the impact of surging solar and wind capacity. Enel, the biggest utility in Italy, which had the most solar PV installed in 2011, highlighted its exposure to reduced peaking prices when it said that a €5/MWh fall in average wholesale prices would translate into a one-third slump in earnings from the generation division.

By Walter Brash (Moronia) The history of energy exploration, mining, and delivery is best understood in a range from benevolent exploitation to worker and public oppression. A company comes into an area, leases land in rural and agricultural areas for mineral rights, increases employment, usually in a depressed economy, strips the land of its resources, creates health problems for its workers and those in the immediate area, and then leaves.
It makes no difference if it’s timber, oil, or coal. In the 1970s and 1980s, the nuclear energy industry promised well-paying jobs, clean energy, and a safe health and work environment. Chernobyl, Three Mile Island, Fukushima Daiichi, and thousands of violations issued by the Nuclear Regulatory Agency, have shown that even with strict operating guidelines, nuclear energy isn’t as clean and safe as claimed. Like all other energy industries, nuclear power isn’t infinite. Most plants have a 40–50 year life cycle. After that, the plant becomes so radioactive hot that it must be sealed.
In the early 21st century, the natural gas industry follows the model of the other energy corporations, and uses the same rhetoric. James M. Taylor, senior fellow at the Heartland Institute, claims on the Institute’s website, “The newfound abundance of domestic gas reserves promises unprecedented energy prosperity and security.”
The energy policy during the eight years of the George W. Bush–Dick Cheney administration was to give favored status to the industry, often at the expense of the environment. In addition to negating Bill Clinton’s strong support for the Kyoto Protocol, signed by 191 countries, to reduce greenhouse-gas emissions, former oil company executives Bush and Cheney pushed to open significant federal land, including the 19 million acre Arctic National Wildlife Refuge (ANWR), to drilling that would disrupt the ecological balance in one of the nation’s most pristine areas.
A study by the Environmental Protection Agency (EPA), published in 2004 concluded that fracking was of little or no risk to human health. However, Wes Wilson, a 30-year EPA environmental engineer, in a letter to members of Congress and the EPA inspector general, called that study “scientifically unsound,” and questioned the bias of the panel, noting that five of the seven members had significant ties to the industry. “EPA’s failure to regulate [fracking] appears to be improper under the Safe Water Drinking Act and may result in danger to public health and safety.”
By Walter Brasch (Moronia)– The natural gas industry defends hydraulic fracturing, better known as fracking, as safe and efficient. Thomas J. Pyle, president of the Institute for Energy Research, a pro-industry non-profit organization, claims fracking has been “a widely deployed as safe extraction technique,” dating back to 1949. What he doesn’t say is that until recently energy companies had used low-pressure methods to extract natural gas from fields closer to the surface than the current high-pressure technology that extracts more gas, but uses significantly more water, chemicals, and elements.
The industry claims well drilling in the Marcellus Shale will bring several hundred thousand jobs, and has minimal health and environmental risk. President Barack Obama in his January 2012 State of the Union, said he believes the development of natural gas as an energy source to replace fossil fuels could generate 600,000 jobs.
However, research studies by economists Dr. Jannette M. Barth, Dr. Deborah Rogers, and others debunk the idea of significant job creation.
Barry Russell, president of the Independent Petroleum Association of America, says “no evidence directly connects injection of fracking fluid into shale with aquifer contamination.” Fracking “has never been found to contaminate a water well,” says Christine Cronkright, communications director for the Pennsylvania Department of Health.
Research studies and numerous incidents of water contamination prove otherwise.
In late 2010, equipment failure may have led to toxic levels of chemicals in the well water of at least a dozen families in Conoquenessing Twp. in Butler County. Township officials and Rex Energy, although acknowledging that two of the drilling wells had problems with the casings, claimed there were pollutants in the drinking water before Rex moved into the area. John Fair disagrees. “Everybody had good water a year ago,” Fair told environmental writer and activist Iris Marie Bloom in February 2012. Bloom says residents told her the color of water changed (to red, orange, and gray) after Rex began drilling. Among chemicals detected in the well water, in addition to methane gas, were ammonia, arsenic, chloromethane, iron, manganese, t-butyl alcohol, and toluene. While not acknowledging that its actions could have caused the pollution, Rex did provide fresh water to the residents, but then stopped doing so on Feb. 29, 2012, after the Pennsylvania Department of Environmental Protection (DEP) said the well water was safe. The residents vigorously disagreed and staged protests against Rex; environmental activists and other residents trucked in portable water jugs to help the affected families. Jospeh P. McMurry of the Marcellus Outreach Butler blog (MOB) declared that residents’ “lives have been severely disrupted and their health has been severely impacted. To unceremoniously ‘close the book’ on investigations into their troubles when so many indicators point to the culpability of the gas industry for the disruption of their lives is unconscionable.”

The Sandia researchers have used metal-organic frameworks (MOFs) to capture and remove volatile radioactive gas from spent nuclear fuel. “This is one of the first attempts to use a MOF for iodine capture,” said chemist Tina Nenoff of Sandia’s Surface and Interface Sciences Department.
The discovery could be applied to nuclear fuel reprocessing or to clean up nuclear reactor accidents. A characteristic of nuclear energy is that used fuel can be reprocessed to recover fissile materials and provide fresh fuel for nuclear power plants. Countries such as France, Russia and India are reprocessing spent fuel. Continue reading »
By Robert Sanders (UC California, Berkeley) University of California, Berkeleyscientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial – able to kill bacteria – for as long as a week after treatment.
A brief spark in air produces a low-temperature plasma of partially ionized and dissociated oxygen and nitrogen that will diffuse into nearby liquids or skin, where they can kill microbes similar to the way some drugs and immune cells kill microbes by generating similar or identical reactive chemicals.

Devices able to produce such plasmas are cheap, which means they could be life-savers in developing countries, disaster areas or on the battlefield where sterile water for medical use – whether delivering babies or major surgery – is in short supply and expensive to produce.
“We know plasmas will kill bacteria in water, but there are so many other possible applications, such as sterilizing medical instruments or enhancing wound healing,” said chemical engineer David Graves, the Lam Research Distinguished Professor in Semiconductor Processing at UC Berkeley. “We could come up with a device to use in the home or in remote areas to replace bleach or surgical antibiotics.”
Low-temperature plasmas as disinfectants are “an extraordinary innovation with tremendous potential to improve health treatments in developing and disaster-stricken regions,” said Phillip Denny, chief administrative officer of UC Berkeley’s Blum Center for Developing Economies, which helped fund Graves’ research and has a mission of addressing the needs of the poor worldwide.
By Andy Bloxham (Telegraph UK) The BBC has dropped a climate change episode from its wildlife series Frozen Planet to help the show sell better abroad.
Frozen Planet, on BBC One, is the latest big budget series from the BBC’s Natural History Unit in Bristol, which was made in association with Discovery Channel and The Open University.
British viewers will see seven episodes, the last of which deals with global warming and the threat to the natural world posed by man.
However, viewers in other countries, including the United States, will only see six episodes.
The environmental programme has been relegated by the BBC to an “optional extra” alongside a behind-the-scenes documentary which foreign networks can ignore.

Observations of Climate Change from Indigenous Alaskans
Personal interviews with Alaska Natives in the Yukon River Basin provide unique insights on climate change and its impacts, helping develop adaptation strategies for these local communities.
The Village of St. Mary’s, Alaska

(Press Release) The USGS coordinated interviews with Yup’ik hunters and elders in the villages of St. Mary’s and Pitka’s Point, Alaska, to document their observations of climate change. They expressed concerns ranging from safety, such as unpredictable weather patterns and dangerous ice conditions, to changes in plants and animals as well as decreased availability of firewood.
“Many climate change studies are conducted on a large scale, and there is a great deal of uncertainty regarding how climate change will impact specific regions,” said USGS social scientist Nicole Herman-Mercer. “This study helps address that uncertainty and really understand climate change as a socioeconomic issue by talking directly to those with traditional and personal environmental knowledge.”
By integrating scientific studies with indigenous observation, these multiple forms of knowledge allow for a more comprehensive understanding of the complex challenges posed by climate change. The indigenous knowledge encompasses observations, lessons and stories about the environment that have been handed down for generations, providing a long history of environmental knowledge. These observations can also help uncover new areas for scientists to study.
The Arctic and Subarctic are of particular interest because these high latitudes are among the world’s first locations to begin experiencing climate change.
The most common statement by interview participants was about warmer temperature in recent years. It was observed to be warmer in all seasons, though most notably in the winter months. In previous generations, winter temperatures dropped to 40 degrees Celsius below freezing, while in present times temperatures only reach 25 C or 30 C below freezing. Moreover, in the rare case that temperatures did drop as low as they had in the past, it was a brief cold spell, in contrast to historic month-long cold spells.
The considerable thinning of ice on the Yukon and Andreafsky Rivers in recent years was the topic of several interviews. Thin river ice is a significant issue because winter travel is mainly achieved by using the frozen rivers as a transportation route via snow machines or sled dogs. Thinning ice shortens the winter travel season, making it more difficult to trade goods between villages, visit friends and relatives, or reach traditional hunting grounds. One interview participant also discussed how the Andreafsky River, on whose banks their village lies, no longer freezes in certain spots, and several people have drowned after falling through the resulting holes in the ice.
The unpredictability of weather conditions was another issue of concern, especially since these communities rely on activities such as hunting, fishing and gathering wild foods for their way of life. One does not want to “get caught out in the country” when the weather suddenly changes.
Vegetation patterns were also observed to be shifting due to the changes in seasonal weather patterns, and this leads to increased difficulty in subsistence activities. Interviews showed the unpredictability from year to year on whether vegetation, particularly salmonberries, could be relied upon. Those interviewed spoke of a change in the range of species of mammals (moose and beaver) as well as a decrease in the number of some bird species (ptarmigan). This is of special concern because of the important role these animals play in the subsistence diets of Alaska Natives. Many also rely on hunting or trapping for their livelihoods.
Participants also discussed lower spring snowmelt flows on the Andreafsky and Yukon Rivers, meaning less logs are flowing down the river. This hampers people’s ability to collect logs for firewood and building materials, placing a strain on an already economically depressed region through increased heating costs and reliance on expensive fossil fuels.
