That promise has proven to be empty, according to Failure to Yield, a report by UCS expert Doug Gurian-Sherman released in March 2009. Despite 20 years of research and 13 years of commercialization, genetic engineering has failed to significantly increase U.S. crop yields.
As environmental concerns threaten to derail natural gas drilling projects across the country, the energy industry has developed innovative ways to make it easier to exploit the nation's reserves without polluting air and drinking water.
Energy companies have figured out how to drill wells with fewer toxic chemicals, enclose wastewater so it can't contaminate streams and groundwater, and sharply curb emissions from everything from truck traffic to leaky gas well valves. Some of their techniques also make good business sense because they boost productivity and ultimately save the industry money -- $10,000 per well in some cases.
Yet these environmental safeguards are used only intermittently in the 32 states where natural gas is drilled. The energy industry is exempted from many federal environmental laws, so regulation of this growing industry is left almost entirely to the states, which often recommend, but seldom mandate the use of these techniques. In one Wyoming gas field, for instance, drillers have taken steps to curb emissions, while 100 miles away in the same state, they have not.
Macquarie University PHD candidate Duane Hamacher said on Monday he had spent the past 18 months researching how Aboriginal people have incorporated the night sky into their culture.
He used an Arrernte dreaming story and Google maps to find a crater at Palm Valley, west of Alice Springs, which had been unknown to geologists.
"The particular Western Arrernte story talked about a star that fell from the sky, making a noise like thunder and crashed into a waterhole in Palm Valley," he told Australian Broadcasting Corporation.

Their study will be published in the February 2010 issue of Nature Neuroscience and is currently available online.
Neuroscientists often classify human memory into three types: declarative memory, such as storing facts or remembering specific events; procedural memory, such as learning how to play the piano or shoot basketballs; and working memory, a type of short-term storage like remembering a phone number. With this particular study, Strowbridge and Larimer, were interested in identifying the specific circuits that could be responsible for working memory.
"Understanding how only the relevant genes are targeted and remain poised for action is a hot topic in embryonic stem cell research," said Joanna Wysocka, PhD, assistant professor of developmental biology and of chemical and systems biology. "Our results shed light on both these questions." Wysocka is the lead author of the research, which will be published in the Dec. 24 issue of Cell.
Jarid2 works through a protein complex called PRC2, for Polycomb Repressive Complex 2. PRCs keep genes quiet by modifying DNA packaging proteins called histones. It's not quite tying a string around a brown paper package, but the concept is similar: Wrapping DNA up neatly around the histones helps it all fit in the tiny space and keeps it out of commission until the appropriate time. That's because, when wrapped, genes can't be converted into proteins to do the work of the cell. PRC2 adds a molecular "Do not open until Christmas" tag to ensure the DNA stays wrapped until it's needed.

Voyager flies through the outer bounds of the heliosphere en route to interstellar space. A strong magnetic field reported by Opher et al in the Dec. 24, 2009, issue of Nature is delineated in yellow.
"Using data from Voyager, we have discovered a strong magnetic field just outside the solar system," explains lead author Merav Opher, a NASA Heliophysics Guest Investigator from George Mason University. "This magnetic field holds the interstellar cloud together and solves the long-standing puzzle of how it can exist at all."
The discovery has implications for the future when the solar system will eventually bump into other, similar clouds in our arm of the Milky Way galaxy.
Aggressive, stinging ants feed on the sugary nectar the plant provides and live in nests protected by its thick bark.
This is the world of "ant guards".
The acacias might appear overrun by them, but the plants have the ants wrapped around their little stems.
These same plants that provide shelter and produce nourishing nectar to feed the insects also make chemicals that send them into a defensive frenzy, forcing them into retreat.
Nigel Raine, a scientist working at Royal Holloway, University of London in the UK has studied this plant-ant relationship.
The park is getting 10 new seismic monitoring stations over the next two years, which will be used jointly at the observatory by the U.S. Geological Survey, Yellowstone National Park and the University of Utah.
Funding for the project will come from a portion of $950,000 in Recovery Act money given to the observatory.

Richard Burton and Elizabeth Taylor in Antony and Cleopatra.
A team of Greek marine archaeologists who have spent years conducting underwater excavations off the coast of Alexandria in Egypt have unearthed a giant granite threshold to a door that they believe was once the entrance to a magnificent mausoleum that Cleopatra VII, queen of the Egyptians, had built for herself shortly before her death.
They believe the 15-tonne antiquity would have held a seven metre-high door so heavy that it would have prevented the queen from consoling her Roman lover before he died, reputedly in 30BC.
"As soon as I saw it, I thought we are in the presence of a very special piece of a very special door," Harry Tzalas, the historian who heads the Greek mission, said. "There was no way that such a heavy piece, with fittings for double hinges and double doors, could have moved with the waves so there was no doubt in my mind that it belonged to the mausoleum. Like Macedonian tomb doors, when it closed, it closed for good."
The discovery of the 1,400-year-old sculptures was made by the archives, archaeology and museums department of Jammu and Kashmir, an official said Sunday.
The Bamiyan Buddhas were destroyed by the Taliban.
The discovery has delighted archaeologists who believe the site in Kargil district could prove a tourist attraction.
The discovery is being publicised to get tourists, especially from Japan and Taiwan to the area. Kargil is 220 km north of Srinagar.
