A nightly occurrence for the first two weeks after April?s hotly contested presidential election results, the sounds of anti-Maduro sentiment are now the street-level soundtrack whenever a government-mandated broadcast, or ?cadena? (chain), takes over the airwaves. Opposition supporters pick up their pots, pans, spoons, and in some cases smart phones, and hang out windows and on balconies to create a cacophonous "cacerolazo," as the noisy protest is called here.

?They didn?t get the result they wanted, so they?re making a lot of noise,? says Vladimir Hernandez, a chavista and supporter of Mr. Maduro from eastern Caracas. ?We?ve heard it before, and we?ll hear it again,? Mr. Hernandez says of the clanging pots and pans.

The cacerolazo has taken such a hold in Venezuela that a number of smart phone apps have been launched to replicate the sound of banging pots and pans. The free Cacerolazo Android app in particular, developed in Argentina, saw over 50,000 downloads in April as news spread worldwide of the protests in Caracas.

?It could be that we?re lazy,? says Marianna Hernandez, whose Samsung Galaxy phone does the work for her in her Caracas neighborhood of Colinas de Santa Monica. ?But after twenty minutes your arms get tired,? she says.

?We simply plug my phone into the stereo and open the window,? Ms. Hernandez says. ?It?s a much greater sound than you can make physically."

She says her friends poke fun at her, but she doesn't mind. "It?s about showing solidarity.?

The regular toc-toc-toc sound of anti-Maduro attitude is countered by fireworks, which explode above the Venezuelan capital?s socialist strongholds. The fireworks are distributed by the city's police force, which encourages demonstrations of support for the country?s ?first chavista president,? as Maduro describes himself.

Everything but the kitchen sink

The cacerolazo is not endemic to Venezuela: Many point to 1970s Chile as the originator. Citizens of Santiago showed their discontent with the economic policies of Salvador Allende?s government through the cacerolazos. The nature of the protest allowed them to express their discontent from the safety of their homes.

The demonstration has since been adopted across Latin America, becoming a common soundtrack throughout the continent, particularly in Buenos Aires, where the app used by many Venezuelans this month was first designed by the COLPIX Argentina studio. Outside of the region it has gained traction as well, most notably last year in Quebec, when students took to the streets to protest a government bill to make mass protest illegal.?

?I?ll keep going?

Both Maduro and opposition candidate Henrique Capriles acted to discourage street-level protests, fearing violence. Maduro closed the streets each night in the weeks following his contested victory, while Mr. Capriles called off plans for a large opposition march.

Capriles turned instead to calling for nightly cacerolazos, instructing his supporters to show their discontent through this nonviolent ? though not particularly peaceful ? protest.

?It won?t change anything,? says Ms. Hernandez, who voted for Capriles in the country?s past two elections. ?Street protests need to be organized, that way you can give a number to those who are against this government.

?The cacerolazo may sound like a lot of people, but it lacks visual impact.?

Maduro won the election by 1.8 percent of the vote, and his victory has been acknowledged by regional leaders including the presidents of Argentina, Brazil, and Colombia. However, Capriles has cited close to 3,200 counts of electoral fraud, including illegal election-day campaigning and police intimidation in opposition-strong polling stations.?

He has petitioned the government for a full recount, and a partial recount is currently underway.

??People will eventually get bored of [the cacerolazo], but I?ll keep going as long as everyone else does," Ms. Hernandez says.

Two more die in Saudi Arabia from SARS-like virus: WHO

GENEVA (Reuters) - Two more people in Saudi Arabia have died from a new strain of coronavirus that has emerged in the Middle East, bringing the toll in the kingdom's latest outbreak to seven, the World Health Organization (WHO) said on Tuesday.

Six other people are infected, one of them critically ill, in an outbreak centered on a health care facility in Al Ahsa governorate in Eastern Province, WHO spokesman Glenn Thomas said in Geneva.

Worldwide, there have been 30 laboratory-confirmed infections with the new virus, including 18 deaths, since it came to scientists' attention last September, he said.

Other strains of coronavirus can cause common colds but also the deadly Severe Acute Respiratory Syndrome (SARS) that emerged in Asia in 2003.

There is no evidence yet of sustained human-to-human spread of the new virus, but there are concerns about clusters of cases reported by the WHO in Saudi Arabia, Jordan and Britain.

A retrospective study in Jordan found that there had been an outbreak of the new virus there as long ago as April 2012, with two confirmed cases and 11 probable ones, including 10 health care workers, Thomas told Reuters.

Saudi Arabia has reported 23 confirmed cases in total, Qatar two, Jordan two, Britain two and the United Arab Emirates one, according to the WHO.

"WHO does not advise special screening (of travelers) nor does it recommend that any trade or travel restrictions," Thomas said, adding that all states should look out for "any unusual patterns" of infection.

Dare We Say It? 'The Show With Vinny' Might Be Worth Checking Out

There's no disputing the Herculean success of MTV's Jersey Shore. Snooki and company have forever influenced the world's perception of that slice of beach called Seaside Heights -- and the people who reside/party heavily within it. But here's a question: Did we fall so hard for its spunky cast members that we'll follow them anywhere they go?

Second U.S. Cargo Plane Crashes in Central Asia

Why can she never win?? Poor Jennifer Aniston, lonely lady of Los Angeles, scorned bride and future crone. All she wants to do is marry Justin Theroux as planned, but of course then her ex, Brad Pitt, had to go and make plans to marry Angelina Jolie this summer, thus ruining everything. So Aniston is pushing back her wedding plans, it's said, to an unknown time, in the fear that the two events will be associated. So tragic. Jennifer Aniston just cannot get a break. ...

Seahorse's armor gives engineers insight into robotics designs

Thursday, May 2, 2013

The tail of a seahorse can be compressed to about half its size before permanent damage occurs, engineers at the University of California, San Diego, have found. The tail's exceptional flexibility is due to its structure, made up of bony, armored plates, which slide past each other. Researchers are hoping to use a similar structure to create a flexible robotic arm equipped with muscles made out of polymer, which could be used in medical devices, underwater exploration and unmanned bomb detection and detonation. Researchers, led by UC San Diego materials science professors Joanna McKittrick and Marc Meyers, detailed their findings in the March 2013 issue of the journal Acta Biomaterialia.

"The study of natural materials can lead to the creation of new and unique materials and structures inspired by nature that are stronger, tougher, lighter and more flexible," said McKittrick, a professor of materials science at the Jacobs School of Engineering at UC San Diego.

McKittrick and Meyers had sought bioinsipiration by examining the armor of many other animals, including armadillo, alligators and the scales of various fish. This time, they were specifically looking for an animal that was flexible enough to develop a design for a robotic arm.

"The tail is the seahorse's lifeline," because it allows the animal to anchor itself to corals or seaweed and hide from predators, said Michael Porter, a Ph.D. student in materials science at the Jacobs School of Engineering. "But no one has looked at the seahorse's tail and bones as a source of armor."

Most of the seahorse's predators, including sea turtles, crabs and birds, capture the animals by crushing them. Engineers wanted to see if the plates in the tail act as an armor. Researchers took segments from seahorses' tails and compressed them from different angles. They found that the tail could be compressed by nearly 50 percent of its original width before permanent damage occurred. That's because the connective tissue between the tail's bony plates and the tail muscles bore most of the load from the displacement. Even when the tail was compressed by as much as 60 percent, the seahorse's spinal column was protected from permanent damage.

McKittrick and Meyers' research group uses a unique technique that applies a series of chemicals to materials to strip them of either their protein components or their mineral components. That allows them to better study materials' structures and properties. After treating the bony plates in the seahorse's tail with the chemicals, they discovered that the percentage of minerals in the plates was relatively low?40 percent, compared to 65 percent in cow bone. The plates also contained 27 percent organic compounds?mostly proteins?and 33 percent water. The hardness of the plates varied. The ridges were hardest, likely for impact protection?about 40 percent harder than the plate's grooves, which are porous and absorb energy from impacts.

The seahorse's tail is typically made up of 36 square-like segments, each composed of four L-shaped corner plates that progressively decrease in size along the length of the tail. Plates are free to glide or pivot. Gliding joints allow the bony plates to glide past one another. Pivoting joints are similar to a ball-and-socket joint, with three degrees of rotational freedom. The plates are connected to the vertebrae by thick collagen layers of connective tissue. The joints between plates and vertebrae are extremely flexible with nearly six degrees of freedom (See picture).

"Everything in biology comes down to structures," Porter said.

The next step is to use 3D printing to create artificial bony plates, which would then be equipped with polymers that would act as muscles. The final goal is to build a robotic arm that would be a unique hybrid between hard and soft robotic devices. A flexible, yet robust robotic gripper could be used for medical devices, underwater exploration and unmanned bomb detection and detonation. The protected, flexible arm would be able to grasp a variety of objects of different shapes and sizes.
