Gunman kills Hamelin politician then himself - The Local
A 74-year-old gunman killed a top official in the northern German town of Hamelin on Friday before shooting himself dead, police said.
Shots were heard shortly after 10am in the city's main administrative building, where 63-year-old Butte was later found dead along with the body of his assailant.
The attacker was not identified. Police refused to comment on media speculation that the shooter was a gun fanatic but did say that the suspect was known to officers in the area. He used a heavy-calibered revolver to shoot Butte.
Butte was married with two adult children and five grandchildren, according to his profile on the district website. By Friday afternoon, his personal website had been taken off line.
Lower Saxony's Interior Minister Boris Pistorius said in a statement that Butte's murder had left him stunned. ?He will be missed by everyone. My thoughts go to his wife and children.?
He served as a police officer, rising through the ranks to become the head of the State Crime Investigations Office of Lower Saxony from 2001 to 2005. He had served as district administrator of Hamelin-Pyrmont, an elected office, since 2005.
The town is best known for the folk tale of the Pied Piper, later popularised by the Brothers Grimm.
Gun violence is rare in Germany, although major massacres in Erfurt in 2002 and Winnenden in 2009 made headlines around the world.
Gun crime, never high in Germany when compared with many other countries, dropped considerably over the past decade ? in 2000, police registered 19,400 crimes in which involved a firearm. By 2011, this figure stood at 11,700.
Of the 2011 statistics, 5,600 were shootings and 132 were incidents in which a gun was involved in a murder, manslaughter or assisted suicide investigation.

Report: American's car shot at following crash in Saudi ... - World News
By Sami Aboudi and Eric Beech, Reuters
DUBAI -- A driver opened fire on a car driven by a U.S. citizen in northern Saudi Arabia after crashing into his vehicle, but there were no casualties, Saudi state news agency SPA reported late on Wednesday.
It was not immediately clear if the incident was a deliberate attack on the American or just a case of road rage.
"The Tabuk police received a report at around 1 p.m. (6 a.m. ET) that a car driven by a resident American citizen had been subjected to a crash and shooting from the driver of the other vehicle while driving on a road in the city of Tabuk," SPA quoted the local police chief as saying.
"There were no injuries but the car was damaged by the accident and shooting," it added.
The kingdom, a key regional U.S. ally and the world's top oil exporter, faced a campaign of attacks by al Qaeda militants targeting foreigners and government facilities between 2003 and 2006. Security forces crushed the militants, arresting and killing many and forcing others to flee the kingdom.

Changing cellulose-forming process may tap plants' biofuel potential

Changing the way a plant forms cellulose may lead to more efficient, less expensive biofuel production, according to Penn State engineers.
"What every biofuel manufacturer wants to do is to get to the sugars," said Jeffrey Catchmark, associate professor of agricultural and biological engineering. "But the structure of cellulose itself can be an obstacle."
Catchmark said that most of a plant's sugar-based energy is locked up in the crystalline structure of cellulose. To make cellulose, plants create long chains of sugar -- glucose -- that are then crystallized and densely packed into tight, ordered bundles resistant to water and other solvents. This bundling may help build strong plant cell walls, but biofuel makers must use extra effort to break down and separate the bundles and the crystalline cellulose to extract the sugars used to ferment fuels.
Using bacteria that produce cellulose as a model to test the process, the researchers discovered an approach for modifying cellulose synthesis in living plants for improved biofuel-making efficiency. During the synthesis process the researchers added glucomannan, a complex carbohydrate found in plants that sticks to cellulose, and found that it altered the structure and assembly of the cellulose, allowing it to be broken down more efficiently.
Another method to ensure the glucomannan is added during cellulose formation requires genetically engineering the plant to express or over-express the enzymes that form the glucomannan, according to the researchers, who applied for a provisional patent on the process.
"In our work, what we are interested in is whether we can improve digestibility by altering the crystal structure or by altering the bundle formation," said Catchmark, who worked with Lin Fang, graduate student in agricultural and biological engineering.
By growing plants with cellulose that is less crystalized and that has fewer structured bundles, biofuel manufacturers will not need to spend as much time and effort breaking down these pre-treated plants, according to the researchers. Currently, biofuel manufacturers must use several industrial processes that are time- and energy-intensive and relatively expensive, including chemical, mechanical and fermentation, to break down the cellulose and separate other materials.
Catchmark said that biofuel manufacturers may be able to further optimize production processes to suit the modified plants for even greater efficiency.
"This will give biofuel makers more options," Catchmark said. "Hopefully, you will need less effort and lower costs with the pre-treatment, but with improved conversion efficiency."
Catchmark said that while the technique was used on bacteria, it could be adapted to various plant species because both plants and certain bacteria share similarities in how they create cellulose. He said that researchers could use the process in both grass and wood plant species, giving biofuel makers additional options. The researchers now plan to test the methods on plants.
