Accused Penn State rioters opt to go straight to trial (Reuters)

HARRISBURG, Pa (Reuters) ? Five Penn State University students decided on Wednesday to go straight to trial on charges they rioted over the firing of football coach Joe Paterno after his assistant coach's arrest for child sex abuse.

The students, who were among six facing the most serious charges in the unrest that inflicted $190,000 in damages, waived their right to a preliminary hearing in Centre County Courthouse in Bellefonte.

It was the same courthouse where former assistant coach Jerry Sandusky last week waived the same right, sending his case directly to trial sometime next year. He is charged with 52 counts of sexual abuse involving 10 boys, many whom he met through a charity he founded for troubled youth.

Fallout over Sandusky's arrest resulted in the firing last month of the popular Paterno, who turned 85 on Wednesday and had been head coach for 46 years. His dismissal triggered a wave of outrage among some students, and in protest about 1,000 of them poured into the streets around campus on November 9.

Angry chants of "Hell no, Joe won't go" dissolved into vandalism, including the upending of a television news van.

A total of 40 students were charged, police said.

The six facing the most serious charge of felony riot, all from Pennsylvania, were accused of tipping over the TV van, which reportedly accounted for most of the $190,000 in damages.

Five of them waived their preliminary hearing on Wednesday, and their was set for March 22. The sixth student has a preliminary hearing set for January 4.

The explosive allegations surrounding Sandusky also forced the university to fire president Graham Spanier, put athletic director Tim Curley on administrative leave and accept the retirement of former top finance official Gary Schultz.

Curley and Schultz have been charged with lying to a grand jury and failing to report a crime.

Sandusky, Curley, and Schultz have maintained their innocence and are free on bail as they await their trials.

Video: Caught in a stampede



>>> tonight a dozen people are recovering from injuries after they ended up in a stampede when thousands of football fans stormed on to the field at oklahoma state university celebrating a big victory over an arch rival. nbc's george lewis has more.

>> reporter: this was the scene as the game ended, the osu cowboys beating the oklahoma sooners 44-10 and winning the big 12 conference championship .

>> the students are storming the field.

>> reporter: fans stampeding on to the grass by the thousands to salute the heroes of the game and tear down the goal posts .

>> i've never been more packed into one area and getting pushed and shoved and just all over the place. people were so excited. and just -- the atmosphere was ridiculous. it was awesome.

>> reporter: but not so awesome was the fact that some people got trampled and others were seriously injured when they tumbled out of the stands.

>> only saw part of it. when they started piling over, i got out of there as fast as i could. i'm looking forward to seeing it on the newscast.

>> down go the goal posts .

>> reporter: some of the fans probably wish they too had gotten out of there. the list of injured included a dozen people, some with fractures. one person fell at least 15 feet on to concrete. the most seriously injured were airlifted to an oklahoma city hospital while others were hauled away by nine ambulances.

>> i was scared this guy had just died and i had a lot of things going through my head. i was just terrified and kind of wanted to cry in the middle of all of the excitement.

Chemists become molecular sculptors, synthesizing tiny, molecular traps

Tuesday, December 6, 2011

Using clever but elegant design, University at Buffalo chemists have synthesized tiny, molecular cages that can be used to capture and purify nanomaterials.

Sculpted from a special kind of molecule called a "bottle-brush molecule," the traps consist of tiny, organic tubes whose interior walls carry a negative charge. This feature enables the tubes to selectively encapsulate only positively charged particles.

In addition, because UB scientists construct the tubes from scratch, they can create traps of different sizes that snare molecular prey of different sizes. The level of fine tuning possible is remarkable: In the Journal of the American Chemical Society, the researchers report that they were able to craft nanotubes that captured particles 2.8 nanometers in diameter, while leaving particles just 1.5 nanometers larger untouched.

These kinds of cages could be used, in the future, to expedite tedious tasks, such as segregating large quantum dots from small quantum dots, or separating proteins by size and charge.

"The shapes and sizes of molecules and nanomaterials dictate their utility for desired applications. Our molecular cages will allow one to separate particles and molecules with pre-determined dimensions, thus creating uniform building blocks for the fabrication of advanced materials," said Javid Rzayev, the UB assistant professor of chemistry who led the research.

"Just like a contractor wants tile squares or bricks to be the same size so they fit well together, scientists are eager to produce nanometer-size particles with the same dimensions, which can go a long way toward creating uniform and well-behaved materials," Rzayev said.

To create the traps, Rzayev and his team first constructed a special kind of molecule called a bottle-brush molecule. These resemble a round hair brush, with molecular "bristles" protruding all the way around a molecular backbone.

After stitching the bristles together, the researchers hollowed out the center of each bottle-brush molecule, leaving behind a structure shaped like a toilet paper tube.

The carving process employed simple but clever chemistry: When building their bottlebrush molecules, the scientists constructed the heart of each molecule using molecular structures that disintegrate upon coming into contact with water. Around this core, the scientists then attached a layer of negatively charged carboxylic acid groups.

To sculpt the molecule, the scientists then immersed it water, in effect hollowing the core. The resulting structure was the trap?a nanotube whose inner walls were negatively charged due to the presence of the newly exposed carboxylic acid groups.

To test the tubes' effectiveness as traps, Rzayev and colleagues designed a series of experiments involving a two-layered chemical cocktail.

The cocktail's bottom layer consisted of a chloroform solution containing the nanotubes, while the top layer consisted of a water-based solution containing positively charged dyes. (As in a tequila sunrise, the thinner, water-based solution floats on top of the denser chloroform solution, with little mixing.)

When the scientists shook the cocktail for five minutes, the nanotubes collided with and trapped the dyes, bringing the dyes into the chloroform solution. (The dyes, on their own, do not dissolve in chloroform.)

In similar experiments, Rzayev and his team were able to use the nanotubes to extract positively charged molecules called dendrimers from an aqueous solution. The nanotubes were crafted so that dendrimers with a diameter of 2.8 nanometers were trapped, while dendrimers that were 4.3 nanometers across were left in solution.

To remove the captured dendrimers from the nanotubes, the researchers simply lowered the pH of the chloroform solution, which shuts down the negative charge inside the traps and allows the captured particles to be released from their cages.

The research on nanotubes is part of a larger suite of studies Rzayev is conducting on bottle-brush molecules using a National Science Foundation CAREER award. His other work includes the fabrication of bottle-brush-based nanomembranes that could be adapted for water filtration, and the assembly of layered, bottle-brush polymers that reflect visible light like the wings of a butterfly do.

(AP) ? Weeks before the U.S. pullout, Iraq's prime minister confidently predicted Saturday that his country will achieve stability and remain independent of its giant neighbor Iran even without an American troop presence.

Nouri al-Maliki also warned of civil war in Iran's ally Syria if Bashar Assad falls ? a view that puts him closer to Tehran's position and at odds with Washington. The foreign policy pronouncement indicates that Iraq is emerging from the shadows of U.S. influence in a way unforeseen when U.S.-led forces invaded eight years ago to topple Saddam Hussein.

"The situation in Syria is dangerous," al-Maliki told The Associated Press during an interview at his office in a former Saddam-era palace in Baghdad's Green Zone. "Things should be dealt with appropriately so that the spring in Syria does not turn into a winter."

The Obama administration has been outspoken in its criticism of Assad's bloody crackdown on protests that the U.N. says has killed more than 4,000 people so far, the bloodiest in a wave of uprisings that have been dubbed the Arab Spring.

Iraq has been much more circumspect and abstained from key Arab League votes suspending Syria's membership and imposing sanctions on the country. That has raised concern that Baghdad is succumbing to Iranian pressure to protect Assad's regime. Tehran is Syria's main backer.

Al-Maliki insisted that Iraq will chart its own policies in the future according to national interests, not the dictates of Iran or any other country.

Some U.S. officials have suggested that Iranian influence in Iraq would inevitably grow once American troops depart.

Both countries have Shiite majorities and are dominated by Shiite political groups. Many Iraqi politicians spent time in exile in Iran under Saddam's repressive regime, and one of al-Maliki's main allies ? anti-American cleric Muqtada al-Sadr ? is believed to spend most of his time in Iran.

"Iraq is not a follower of any country," al-Maliki said. He pointed out several areas in which Iraq had acted against Iran's desires, including the signing of the security agreement in 2008 that required all U.S. forces to leave Iraq by the end of this year. Iran had been pushing for all American troops to be out of the country even sooner.

"Through our policies, Iraq was not and will not be a follower of another country's policies," he said.

But he also took pains to emphasize that Iraq did want to maintain good relations with Iran as the two countries share extensive cultural, economical and religious ties.

"Clearly, we are no enemy to Iran and we do not accept that some who have problems with Iran would use us as a battlefield. Some want to fight Iran with Iraqi resources as has happened in the past. We do not allow Iran to use us against others that Iran has problems with, and we do not allow others to use us against Iran," he said.

The prime minister defended his country's stance when it comes to how to address the instability roiling neighboring Syria right now.

The U.N.'s top human rights official said this week that Syria is in a state of civil war and that more than 4,000 people have been killed since March.

Al-Maliki said Iraq believes the Syrian people's rights should be protected and that his government has told the Syrian regime that the age of one party and one sect running the country is over. Syria is ruled by a minority Alawite regime, an offshoot of Shiism, that rules over a Sunni Muslim majority.

The Iraqi prime minister even said that members of the Syrian opposition had recently asked to come to Iraq, and that his government would meet with them. But he distanced himself from calls for Assad's ouster, warning that could plunge the country into civil war.

"The killing or removal of President Bashar in any way will explode into an internal struggle between two groups and this will have an impact on the region," al-Maliki said.

"My opinion ? I also lived in Syria for more than 16 years ? is that it will end with civil war and this civil war will lead to alliances in the region. Because we are a country that suffered from the civil war of a sectarian background, we fear for the future of Syria and the whole region," he said.

Al-Maliki also insisted his forces were ready to take over security during a wide-ranging discussion on where his country stands ahead of the Dec. 31 departure of all American troops.

"Nothing has changed with the withdrawal of the American forces from Iraq on the security level because basically it has been in our hands," he said.

The U.S. withdrawal has occurred in stages, with the American military pulling out of the cities in 2008, leaving the soldiers largely confined to bases as Iraqi security forces took the lead. About 13,000 U.S. troops are still in the country, down from a one-time high of about 170,000.

Al-Maliki said he was grateful to the United States for overthrowing Saddam.

"We appreciate that, no doubt," the prime minister said, adding he was not worried about a resumption of the type of sectarian warfare that pushed his own country to the brink of civil war in the years following the 2003 U.S.-led invasion.

On the contrary, he said violence would decline because the Americans' departure would remove one of the main reasons for attacks.

"What was taking place during the presence of the American forces will decrease in the period after the withdrawal," he said. "Some people find a pretext in the presence of the American forces to justify their acts, but now what justification will they come up with?"

Gingrich leads in Iowa poll (AP)

WASHINGTON ? Newt Gingrich has taken the lead in a poll of Republican voters in Iowa, followed by Ron Paul and Mitt Romney.

Former House Speaker Gingrich received support from 25 percent of likely voters in the leadoff Iowa caucus, while Texas congressman Paul had 18 percent and former Massachusetts Gov. Mitt Romney had 16 percent in the Des Moines Register's Iowa Poll released Saturday.

Gingrich's support stood at just 7 percent in the most recent Iowa Poll, conducted in late October. Businessman Herman Cain, who suspended his campaign today amid claims of sexual misconduct, was at 8 percent in the latest poll, down from 23 percent in October. Minnesota Rep. Michele Bachmann was also at 8 percent.

Texas Gov. Rick Perry and former U.S. Sen. Rick Santorum of Pennsylvania were at 6 percent each, and former Utah Gov. Jon Huntsman was at 2 percent.

The new poll of 401 likely Republican caucusgoers has a margin of error of plus or minus 4.9 percentage points.

11 First-Class Fuel Sippers—That Aren't Hybrids

Hybrid schmybrid. From diesel burners to direct-injection gasoline engines, this current crop of efficiency stars has many hybrids shaking in their boots. By James Tate

1 of 11

2012 Ford Mustang

EPA Fuel Economy (city/highway): 19/31

Let's own up to a few truths here. First, long before the Toyota Prius, there were many people out there looking for fuel-efficient autos. Second, hybrids are not a perfect or permanent solution. From the costs (environmental and otherwise) of mining raw materials for hybrid batteries to their codependent relationship with the internal combustion engine, there's an argument to be made that a great conventional engine is a better option for drivers seeking to use less fuel. And third, performance and mpg are not, in fact, diametrically opposed.

Take the Mustang. We start our list here of nonhybrid fuel sippers here because the Ford is the coolest, and because it's the easiest for hybrid devotees to dismiss. Yes, it's a 305-hp pony car, and yes, 19 mpg in the city isn't anything to brag about. But 31 highway? Out of a V-6 that chucks more than 300 horses? If your commute involves some highway time, you owe it to yourself to consider the Mustang. Efficiency has rarely been more fun.
