Yemen s Saleh vows to leave, troops kill 9 protesters

SANAA: Yemeni President Ali Abdullah Saleh said on Saturday he would leave for the United States and give way to a successor, hours after his forces killed nine people demanding he be tried for killings of protesters over the past year.

But Saleh, who agreed to step down last month under a deal cut by his wealthier neighbours who fear civil war in Yemen will affect them, did not say when he would depart and vowed to play a political role again, this time opposed to a new government.

The bloodshed and political uncertainty hinted at the chaos which oil giant Saudi Arabia and Saleh's former backers in Washington fear Yemen could slip into, giving the country's al Qaeda wing a foothold overlooking oil shipping routes.

Troops from units led by Saleh's son and nephew opened fire with guns, tear gas and water cannon against demonstrators who approached his compound in the capital Sanaa after marching for days from the southern city of Taiz, chanting "No to immunity".

Mohammed al-Qubati, a doctor at a field hospital that has treated protesters during 11 months of mass demonstrations against Saleh, said some 90 people suffered gunshot wounds in addition to the nine killed. About 150 other people were wounded by tear gas canisters or incapacitated by gas, he said.

The marchers denounced the deal Saleh agreed last month giving him immunity from prosecution in exchange for handing power to his deputy, who is to work with an interim government including opposition parties before a February presidential election.

That plan, crafted by the Gulf Cooperation Council and mirrored in the terms of a U.N. Security Council resolution, has been bitterly condemned by youth protesters who demand Saleh face trial and his inner circle be banned from holding power.

"The blood of the martyrs has been sold for dollars," shouted protesters, before forces from the Republican Guard and Central Security Forces attacked on roads leading to Saleh's compound, which was surrounded by tanks and armoured vehicles.

Stressed Chinese fight back with pillows

SHANGHAI - A whirlwind of pillows bearing the names of bosses and teachers filled the air as hundreds of Chinese gathered to blow off stress in Shanghai, staging a massive pillow battle.

The annual event marked its fifth year with such a surge in interest from stressed young office workers and students that organizers held two nights of pillow fighting before Christmas Day and plan another for Dec 30.

"Nowadays there are many white collar workers and students that are facing huge pressures at work and at school, so we hope to give them an outlet to release their stress before the end of the year," said Eleven Wang, the founder and mastermind behind the epic pillow fights.

"Sometimes we have pressure on us by our bosses, teachers and exams, so today we can go crazy. Everyone will get to write onto the pillows the names of their bosses, teachers and exam subjects, and enjoy and vent to the maximum," he added.

"After releasing the stress, we can once again face our daily life with joy."

Pillows were handed out at the door as participants entered, then emotion stoked by a rock concert, with many on the floor of the huge event space rocking and waving their pillows in time to the music.

Then came the fighting.

Pillows filled the air, with many combatants opting for throwing rather than using them to whack opponents. A few hapless participants shielded their heads with as many pillows as they could hold, but most ventured eagerly in to the fray.

"I really enjoyed the fight, but my friend was useless. He joined in for two ticks and could not go on, he was afraid of getting beaten by other people," said 24-year-old Chen Yi.

"I thought it was pretty meaningful. I've just been working so much (at the office) and never get to break out in a sweat, so it felt really good."

Others gamely said they enjoyed the experience even though they ended up as attackees rather than attackers.

"I don't know who pushed me, but all of a sudden I was in the pile of pillows, where I became the target of many people, and was beaten by all sorts of people," said university student Zhu Shishan. "Very meaningful."

Shearing triggers odd behavior in microscopic particles

ScienceDaily (Dec. 23, 2011) ? Microscopic spheres form strings in surprising alignments when suspended in a viscous fluid and sheared between two plates -- a finding that will affect the way scientists think about the properties of such wide-ranging substances as shampoo and futuristic computer chips.

A team of scientists at Cornell University and the University of Chicago have imaged this behavior and have explained the forces causing it for the first time. Its findings appear in the Dec. 19-23 early edition of the Proceedings of the National Academy of Sciences.

"The experimental breakthrough revealed that these string structures were perpendicular to the shear instead of parallel to it, contrary to what many in the field were expecting," said Aaron Dinner, associate professor in chemistry at UChicago and a study co-author.

The experiment was led by Itai Cohen, associate professor of physics at Cornell, who custom-built a device that would enable him simultaneously to exert shearing forces on suspended colloids (the spheres) and image the resulting motion at 100 frames per second with a confocal microscope. Imaging speed was critical to the experiment because the string-like structures appear only at certain shear rates.

"This issue of strings has been pretty controversial. I'm not sure that we've solved all the controversies associated with them, but at least we've made a step forward," Cohen said.

Shearing forces affect the dynamic behavior of paint, shampoo and other viscous household products, but an understanding of these and related phenomena at the microscopic level has largely eluded a detailed scientific understanding until the last decade, Dinner noted.

Futuristically speaking, these forces potentially could be harnessed to produce microscopic patterns on computer chips or biosensors via special paints that flow easily when layered in one direction, but becomes hard when layered in another direction.

Cohen's objective was more scientifically immediate: to devise an experiment that would overcome the technical difficulties associated with measuring the mechanical properties of the colloidal strings while also imaging their formation. "The holy grail is to be able to understand how the structure leads to the mechanical properties and then to be able to control the mechanical properties by influencing the structure," Cohen explained.

Cohen, PhD'01, received his doctorate in physics at UChicago, as did lead author Xiang Cheng, PhD'09, a postdoctoral associate at Cornell who assembled the team; and co-author Xinliang Xu, PhD'07, a postdoctoral scholar at UChicago. The study co-authors also included Stuart Rice, the Frank P. Hixon Distinguished Service Professor Emeritus in Chemistry at UChicago and a 1999 recipient of the National Medal of Science.

As members of UChicago's Materials Research Science and Engineering Center, Rice and Dinner are part of a larger effort to determine how materials behave under the influence of various dynamic forces. Some of their physics colleagues analyze forces operating on macroscopic scales, while chemists such as Rice and Dinner attempt to assess how those findings might apply to microscopic phenomena.

Rice and his UChicago co-authors used computer simulations to develop a precise explanation for the string-like colloidal structures that formed in the Cornell experiment. "The previous simulations all left out the consequences of the flow created in the supporting fluid as the particles move, the so-called hydrodynamic forces," Rice said.

"A very large fraction of the work in the field neglects hydrodynamic forces because it's hard. You try and get away with what you can," Rice noted with amusement. "But in this case it turns out that the inclusion of those forces is the crucial element."

The simulations allowed the UChicago team to control various experimental parameters to assess their relative importance. "You can play God," Rice said. "The important finding is the overwhelming role of the lubrication forces and the anti-intuitive result that they create."

The lubrication force comes into play when two colloids come together to behave much like macroscopic ball bearings soaking in a reservoir of goopy fluid.

"Pulling them apart would be working against the fluid and so it would be very hard," Dinner said. "So actually, when you get a collision in these colloidal systems, those lubrication forces hold them together much longer, and that actually allows for some of the unique dynamics that give rise to the structure. That was specifically what the simulations showed."

Xu, the UChicago postdoctoral scholar, adapted a mathematical formula developed by John Brady at the California Institute of Technology to simplify the simulations, which ran for days and weeks at a time. "Every time you rearrange the particles, the interactions are different," Rice said. "If you were to calculate that directly, it would be extremely tedious."

But Xu's adapation of Brady's formula enabled him to generate a table of hydrodynamic interactions that listed each particle configuration. Xu found that he could accurately simplify the simulation by focusing on just two of the experiment's seven layers of colloids.

The simulations and the experiment showed that even after three centuries of study, the field of hydrodynamics continues to yield surprising discoveries. "We are still discovering novel behavior that is fundamentally determined by the hydrodynamics," Rice noted.

Mexico makes huge meth precursor chemicals seizure (AP)

MEXICO CITY ? Mexico said Friday that it seized 229 metric tons of precursor chemicals used to make methamphetamine, the third such huge seizure this month at the Pacific port of Lazaro Cardenas, all of which were bound for a port in Guatemala.

The seizure brings to more than 534 tons the amount of meth chemicals detected at the Mexican port in less than a month.

Authorities announced on Dec. 19 that they had found almost 100 metric tons of methylamine at Lazaro Cardenas, and earlier said that 205 tons of the chemical had been found there over several days in early December.

Experts familiar with meth production call it a huge amount of raw material, noting that under some production methods, precursor chemicals can yield about half their weight in uncut meth.

The Attorney General's Office said the most recent seizure was found in 1,600 drums, and had been shipped from Shanghai, China. All three shipments originated in China and were destined for Puerto Quetzal, Guatemala.

The office has not indicated which cartels may have been moving the chemicals, but U.S. officials have noted that the Sinaloa cartel, Mexico's most powerful, has moved into meth production on an industrial scale.

Sinaloa also has operations in Guatemala, and given recent busts by the Mexican army of huge meth processing facilities in Mexico, the gang may have decided to move some production to the Central American country.

Lazaro Cardenas is located in the western Michoacan state, which is dominated by the Knights Templar cartel and previously by the La Familia group.

However, a series of arrests, deaths and infighting may have weakened those gangs' ability to engage in massive meth production.

Also Friday, the attorney general's office in the Gulf coast state of Veracruz reported that it had found ten bodies in an area along the border with the neighboring state of Tamaulipas. The office said investigators were alerted to the bodies by a tip, and are working to identify them and the cause of death.

The area has been the scene of bloody battles between the Gulf and Zetas cartels.

Finally Friday, federal police captured Javier Mercado Guerrero, alias "El Indio," who allegedly led the operations of the Zetas drug cartel in the Veracruz city of Poza Rica and surrounding areas inland.

Police said Mercado Guerrero had served as a local police officer in 2010, and passed information to the Zetas.

Local police in Veracruz have become so corrupt that on Wednesday, the government decided to dissolve the entire police force in the state's largest city, also known as Veracruz, and sent the Navy in to patrol.

State spokeswoman Gina Dominguez said 800 police officers and 300 administrative employees were laid off. Dominguez said they can apply for jobs in a state police force, but must meet stricter standards.
