MEXICO CITY (AP) ? Eleven young people were brazenly kidnapped in broad daylight from an after-hours bar in Mexico City's Zona Rosa, a normally calm district of offices, restaurants, drinking spots and dance clubs, anguished relatives said Thursday.
The apparent mass abduction purportedly happened sometime between 10 a.m. and noon on Sunday morning just off the Paseo de la Reforma, the city's main boulevard, near the Angel of Independence monument and only about 1? blocks from the U.S. Embassy.
The incident was the second recent high-publicity blemish for the city's largely unregulated entertainment scene, coming 20 days after the grandson of American civil rights activist Malcolm X was beaten to death at another tough bar in the downtown area.
Calling for authorities to find their loved ones, family members marched Thursday morning from the Interior Department building to the Zocalo, the city's main square. Later they protested outside the bar, which bears a sign that reads Bicentenario Restaurante-Bar, and demanded to see the bar's surveillance video.
"How could so many people have disappeared, just like that, in broad daylight?" said Josefina Garcia, mother of Said Sanchez Garcia, 19, her only son. "The police say they don't have them, so what, the earth just opened up and swallowed them?"
She said her son wasn't involved in any criminal activity, and worked at a market stall selling beauty products.
City prosecutors said they had received 11 missing-person reports, but Garcia said residents of the tough downtown neighborhood of Tepito where the victims live thought as many as 15 or 16 people could have been abducted.
The known missing include six men, most in their 20s, a 16-year-old boy and four young women.
While no clear motives had been revealed in the attack, residents of Tepito said there has been a wave of abductions of neighborhood young people in recent months that could be related to organized crime activities. Tepito is the center of black market activities in the city, where guns, drugs, stolen goods and contraband are widely sold.
Mass abductions have been rare in Mexico City, but are common in parts of the country where drug cartels operate and are fighting with rival gangs over territory.
Prosecutors slapped closure stickers on the front doors of the Mexico City bar Thursday, with inscriptions saying the city's anti-kidnapping unit was investigating abductions at the site.
Late Thursday night, dozens of members of a special police intervention unit, many carrying automatic weapons and wearing helmets and bullet-proof vests, blocked off the street in front of the bar and searched inside. Officers would not comment on what they were looking for.
Isabel Fonseca, whose brother is among those missing, said a man who escaped told her that masked men arrived in several white SUVs and took the group away. She said her brother, Eulogio Fonseca, is a street vendor who sells cellphone accessories.
"We want them alive," Fonseca said. "They went out to have fun; they are not criminals."
Mexico City's chief prosecutor, Rodolfo Rios, said investigators had been able to glean very little information on the disappearances.
Relatives believe the youths were at the club, which they said is called "Heaven," around midmorning Sunday, when waiters and bar employees herded them out to the street and armed men bundled them into waiting vehicles and spirited them away.
Rios said police had not located any employees of the bar and no other witnesses had presented themselves.
"We aren't sure what exactly occurred," he said. "No witness has come forward to say anything about any armed gang."
The bar is down a side street from two high-rise office buildings that look out on Reforma and sits across the narrow road from beauty salons and a sushi restaurant.
Guillermo Bustamante, owner of one the beauty parlors, said the street bustles every Saturday morning with people coming and going from the bar.
"Every time we arrived on Saturdays, we would see weird people coming out of that bar," Bustamante said. "There would be many Hummers parked outside and men walking out with a woman on each arm."
Bars of questionable character are often allowed to continue operating, even though drugs may be sold inside and the businesses frequently violate rules governing closing times, parking and serving alcohol to minors.
Malcolm Shabazz, grandson of the late Malcolm X, died May 9 in a fight that erupted after he and a friend were presented with a $1,200 bill at a seedy bar near Plaza Garibaldi, a gathering place for mariachi bands in a rough neighborhood in the downtown area. Two waiters at the bar have been arrested in connection with Shabazz's death.
In June 2008, police raided another Mexico City bar to investigate drug and alcohol sales to minors. A stampede ensued as panicked youths rushed for the exits and police tried to stop them. A dozen young people died in the stampede.

TIGHAR
Is this the Electra? A grainy sonar image captured off an uninhabited tropical island in the southwestern Pacific republic of Kiribati might represent the remains of Amelia Earhart's plane.
By Rossella Lorenzi
Discovery News
A grainy sonar image captured off an uninhabited tropical island in the southwestern Pacific republic of Kiribati might represent the remains of the Electra, the two-engine aircraft legendary aviator Amelia Earhart was piloting when she vanished on July 2, 1937 in a record attempt to fly around the world at the equator.
Released by The International Group for Historic Aircraft Recovery (TIGHAR), which has long been investigating Earhart's last, fateful flight, the images show an "anomaly" resting at the depth of about 600 feet in the waters off Nikumaroro island, some 350 miles southeast of Earhart's target destination, Howland Island.
According to TIGHAR researchers, the sonar image shows a strong return from a narrow object roughly 22 feet long oriented southwest/northeast on the slope near the base of an underwater cliff. Shadows indicate that the object is higher on the southwest (downhill side). A lesser return extends northeastward for about 131 feet.
"What initially got our attention is that there is no other sonar return like it in the entire body of data collected," Ric Gillespie, executive director of TIGHAR, told Discovery News.
"It is truly an anomaly, and when you're looking for man-made objects against a natural background, anomalies are good," he added.
A grainy image captured near an uninhabited island in the Pacific could possibly be the wreckage of Amelia Earhart's plane, archaeologists say. NBC's Brian Williams reports.
A number of artifacts recovered by TIGHAR during 10 expeditions have suggested that Earhart and her navigator, Fred Noonan, made a forced landing on the island's smooth, flat coral reef. Gillespie and his team believe the two became castaways and eventually died there.
In July 2012, Gillespie and his crew returned to Nikumaroro to carry out an underwater search for the plane with a torpedo-shaped Autonomous Underwater Vehicle (AUV) and a Remote Operated Vehicle (ROV).
Multi-beam sonar mounted on the ship mapped the underwater terrain and the AUV collected a volume of side-scan data along roughly 1.3 nautical miles of shoreline off the west end of Nikumaroro, while the ROV, capable of reaching depths of 3,000 feet, produced hours upon hours of high-definition video.
Plagued by a number of technical issues and a difficult environment, the hunt did not result in the immediate identification of pieces from Earhart's Lockheed Electra aircraft.
As they returned from the data collection trip, TIGHAR researchers began reviewing and analyzing all of new material recovered from the underwater search.
They identified a small debris field of objects at the depth of 200 feet, which TIGHAR forensic imaging specialist Jeff Glickman described as consisting of man-made objects.

Amelia Earhart, walking in front of her twin engine plane, the Electra.
Located distinctly apart from the debris field of the SS Norwich City, a British steamer which went aground on the island's reef in 1929, the site features objects which appear consistent with the interpretation made by Glickmann of a grainy photograph of Nikumaroro's western shoreline.
The grainy photo was shot by British Colonial Service officer Eric R. Bevington in October 1937, just three months after Amelia's disappearance on July 2, 1937. It revealed an apparent man-made protruding object on the left side of the frame.
Forensic imaging analyses of the picture found the mysterious object consistent with the shape and dimensions of the wreckage of landing gear from Earhart's plane.
"The Bevington photo shows what appears to be four components of the plane: a strut, a wheel, a worm gear and a fender. In the debris field there appears to be the fender, possibly the wheel and possibly some portions of the strut," Glickman told Discovery News.
A new twist in the search occurred last March when Richard Conroy, a member of TIGHAR?s online Amelia Earhart Search Forum, spotted an anomaly in a sonar map posted online.
"The anomaly gives the impression of being an object that struck the slope at the base of the second cliff at a depth of 613 feet, then skidded in a southerly direction for about 131 feet before coming to rest," Gillespie said.
In its underwater search, TIGHAR missed the place where the anomaly appears by only a few hundred feet.
"If only we had continued just that little bit further," Wolfgang Burnside, president of Submersible Systems Inc. and the inventor and pilot of ROV used to conduct the underwater search, said.
He found the target "very promising, definitely not a rock, and it's in the correct location on the reef."
"It also shows what I interpret as 'drag' markings on the reef above and to the north behind the target, as it obviously hasn't quite settled into its final resting place yet," Burnside said.
Gillespie offers another explanation. ?The apparent ground scar behind the object may also be a trail of internal components that spilled from the ripped-open fuselage.?
The anomaly appears to be the right size and shape to match the Electra wreckage and lines up nicely with the Bevington Object and Jeff Glickman's debris field.
According to Gillespie, the evidence found so far suggests a reasonable sequence of events:
? Earhart makes a safe landing on the dry reef and sends radio distress calls for at least five days.
? Before the seventh day, when Navy search planes arrive, rising tides and surf knock the Electra off its landing gear and push it over the reef edge into the ocean, leaving a landing gear assembly (the Bevington Object) behind, jammed in the reef. Earhart and Noonan become castaways on the uninhabited, waterless atoll.
? The landing gear assembly stays jammed in the reef at least until October, when Bevington took the photo, but at some point it breaks free and sinks, ending up in the catchment area at 200 feet, where Glickman spotted pieces of it in the video.
? After going over the edge, the airplane is battered by the surf and sinks within a few minutes in the shallow water just past the reef edge. Subsequent storms cause pieces of wreckage to wash ashore, where they are found and used by the island's later residents.
? Eventually, the fuselage goes over the cliff, hits the slope at the bottom of the cliff at 600 feet and skids for a ways before coming to rest more or less on its side, with the starboard-side wing stub sticking up.
The only way to be absolutely sure that the anomaly is indeed Amelia's plane is by sending another expedition to the island, but that will depend upon the ability of TIGHAR, a nonprofit institute that relies on sponsorships and contributions from the public, to raise the needed funding.
"We currently project that it will take nearly $3 million to put together an expedition that can do what needs to be done. It's a lot of money, but it's a small price to pay for finding Amelia," Gillespie said.

Treatments against hepatitis C virus have only been partially successful. A major problem is that antivirals generate drug resistance. Now Seong-Wook Lee of Dankook University, Yongin, Republic of Korea and his collaborators have developed agents that bind to the business end of a critical protein, disabling it so successfully that no resistance has arisen. The research is published in the June 2013 issue of the Journal of Virology.
The target protein for the new agents is the NS5B replicase protein, which is the central catalytic enzyme in HCV replication. The researchers developed "RNA aptamers" which bind tightly to the part of that protein that performs the catalysis, disabling the replicase. Aptamers are short nucleic acids or peptides that provide the same level of recognition and binding ability that is common to antibodies.
The aptamers inhibited HCV replication without generating escape mutants, says Lee. Moreover, the aptamers inhibited diverse genotypes of HCV, neither causing toxicity nor inducing innate immunity, he says. Lee notes that in the study, therapeutic quantities of ligand-conjugated aptamer penetrated the liver tissue in the mice, raising the likelihood that therapeutically effective quantities could ultimately be achieved in HCV patients.
Roughly 170 million people worldwide are infected with HCV, says Lee, and it is the major cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. There is as yet "no efficient and specific single regimen against HCV," says Lee. Current treatments are associated with many side effects, partly because rapid generation of drug-resistant virus has forced clinicians to use combinations of several drugs, resulting in greater numbers of side effects in patients than if a single agent could be used. And even with the drug combinations only some patients can generate a sustained antiviral response.

Submerged mines were once the scourge of sea warfare, silently lurking in bays and channels to blow a hole in your hull. That's why the US military has developed a trident countermeasure, hunting for the underwater bombs from below the waves
Built by famed defense contractor Sikorsky, the Sea Dragon is derived from the equally mammoth CH-53E Super Stallion
While the Super Stallion is outfitted with a large cache of weaponry for airborne assaults, the Sea Dragon is instead primarily employed in long range demining operations, Airborne Mine Countermeasures (AMCM). As such, the helicopter carries a variety of mine-sweeping systems such as magnetic minesweeping sleds, mechanical minesweepers, side-scan sonar, GPS, and Doppler radar. The Sea Dragon's digital flight-control system is designed specifically to keep the chopper stable as it's dragging a sled through mine-filled waters. That's not to say it's completely defenseless, the Sea Dragon can be fitted with a .50-cal GAU-21 machine gun for its secondary assault support missions and includes a pair of machine gun mine countermeasures.
While recent upgrades such as night vision systems and forward looking infrared (FLIR) will extend the Sea Dragon's effective operational lifetime, both it and the Super Stallion may soon be replaced by an even more monstrous flying machine, the Sikorsky CH-53K.

Magician poses a potential threat to Dawn Approach in Investec Derby ? Horseracing News?
Magician has emerged as a serious contender for winning the Investec Derby (Group 1) (Entire Colts & Fillies) at Epsom in England on Saturday, June 4, 2013.
The young challenger from Ireland has been delivering some solid performances in the ongoing season and will definitely cause plenty of problems for his rivals.
Looking at the entry list for the Derby, it is clear that Dawn Approach will be the one to beat. He has been dominating his opponents since the start of his career, which will help him attract the maximum number of bets in his favour.
However, his trainer Jim Bolger is keeping an eye on the opponents and said, ?I thought Magician's performance on Saturday was very smart. Dawn Approach is continuing to please me and I am looking forward to running him in the Investec Derby at Epsom Downs on Saturday.?
Overall, Dawn Approach has participated in seven races, winning all of them. The impressive thing about him is that he has always been dominant against his rivals. Due to this, it seems pretty unlikely that someone will be able to end his winning streak.
Coral spokesman David Stevens is keeping an eye on the participants of the Investec Derby and he claimed, ?Dawn Approach remains odds-on favourite for the Investec Derby, but his closest challenger in the betting could turn out to be a fellow 2,000 Guineas winner in Magician.?
The latter of the two runners will be making an appearance in a race against Battle Of Marengo this weekend. Both of them have been lined up for action in the Derby, so they will be looking to make an impression in the event before the major clash.
Magician?s performances in his debut season were not satisfactory but he has become a serious threat for others in 2013. He has been dominating the races this year, which shows that he is an improved performer and does not like settling for lower positions.
The three-year-colt has now improved his overall strike rate, winning three races out of six. Moreover, he has also finished as a runner up once, which shows that he is not an easy nut to crack.

The Catholic Church's top exorcist Father Gabriele Amorth.
Father Gabriele Amorth, 88, who also heads the International Association of Exorcists, told The Sunday Times?that he will ask Pope Francis to allow all priests the right to do exorcisms without the church's approval. According to the report, priests currently need special approval from their bishop to perform the rite and it is rarely granted.
"I will ask the pope to give all priests the power to carry out exorcisms, and to ensure priests are properly trained for these starting with the seminary. There's a huge demand for them," said Father Amorth.
He explained that he was inspired to make the request after watching Pope Francis perform what he insists was an exorcism on a man "possessed by four demons"?in St. Peter's Square.
"The pope is also the Bishop of Rome, and like any bishop he is also an exorcist," Amorth reportedly told?La Repubblica newspaper. "It was a real exorcism. If the Vatican has denied this, it shows that they understand nothing."
"There was now, more than ever, a need for exorcists to combat people possessed by 'sorcerers' and 'Satanists,'" he noted in that report.
Follow us
An 84-page update of exorcism rites compiled in 1614 and drawn up in 1998 stipulates how Catholic priests trained as exorcists should operate. According to the guidelines established by the church, they have to follow a ritual known as "De exorcismis et supplicationibus quibusdam," or "Of exorcisms and certain supplications."
Amorth explained?that Pope Francis' exorcism on May 19 helped to balance the growing atheism in the world where people don't believe in the Devil anymore.
"We live in an age in which God has been forgotten. And wherever God is not present, the Devil rules," said Amorth.
"Today, unfortunately, bishops don't appoint sufficient exorcists. We need many more. I hope that Rome will send out directives to bishops around the world calling on them to appoint more exorcists."
Amorth is also an outspoken critic of yoga and Harry Potter books and dismissed them as ungodly hobbies.
"Practicing yoga brings evil as does reading Harry Potter. They may both seem innocuous but they both deal with magic and that leads to evil," he said.
In addressing Harry Potter, he said: "People think it is an innocuous book for children but it's about magic and that leads to evil. In Harry Potter the Devil is at work in a cunning and crafty way, he is using his extraordinary powers of magic and evil."
"Satan is always hidden and the thing he desires more than anything is for people to believe he does not exist," he noted. "He studies each and every one of us and our tendencies towards good and evil and then he tempts us."

LIVERMORE, Calif. -- Lawrence Livermore scientists have discovered and demonstrated a new technique to remove and store atmospheric carbon dioxide while generating carbon-negative hydrogen and producing alkalinity, which can be used to offset ocean acidification.
The team demonstrated, at a laboratory scale, a system that uses the acidity normally produced in saline water electrolysis to accelerate silicate mineral dissolution while producing hydrogen fuel and other gases. The resulting electrolyte solution was shown to be significantly elevated in hydroxide concentration that in turn proved strongly absorptive and retentive of atmospheric CO2.
Further, the researchers suggest that the carbonate and bicarbonate produced in the process could be used to mitigate ongoing ocean acidification, similar to how an Alka Seltzer neutralizes excess acid in the stomach.
"We not only found a way to remove and store carbon dioxide from the atmosphere while producing valuable H2, we also suggest that we can help save marine ecosystems with this new technique," said Greg Rau, an LLNL visiting scientist, senior scientist at UC Santa Cruz and lead author of a paper appearing this week (May 27) in the Proceedings of the National Academy of Sciences.
When carbon dioxide is released into the atmosphere, a significant fraction is passively taken up by the ocean forming carbonic acid that makes the ocean more acidic. This acidification has been shown to be harmful to many species of marine life, especially corals and shellfish. By the middle of this century, the globe will likely warm by at least 2 degrees Celsius and the oceans will experience a more than 60 percent increase in acidity relative to pre-industrial levels. The alkaline solution generated by the new process could be added to the ocean to help neutralize this acid and help offset its effects on marine biota. However, further research is needed, the authors said.
"When powered by renewable electricity and consuming globally abundant minerals and saline solutions, such systems at scale might provide a relatively efficient, high-capacity means to consume and store excess atmospheric CO2 as environmentally beneficial seawater bicarbonate or carbonate," Rau said. "But the process also would produce a carbon-negative 'super green' fuel or chemical feedstock in the form of hydrogen."
Most previously described chemical methods of atmospheric carbon dioxide capture and storage are costly, using thermal/mechanical procedures to concentrate molecular CO2 from the air while recycling reagents, a process that is cumbersome, inefficient and expensive.
"Our process avoids most of these issues by not requiring CO2 to be concentrated from air and stored in a molecular form, pointing the way to more cost-effective, environmentally beneficial, and safer air CO2 management with added benefits of renewable hydrogen fuel production and ocean alkalinity addition," Rau said.
The team concluded that further research is needed to determine optimum designs and operating procedures, cost-effectiveness, and the net environmental impact/benefit of electrochemically mediated air CO2 capture and H2 production using base minerals.

EPHRATAH, N.Y. (AP) ? The search for a brain cancer patient who was on the volunteer medical flight that crashed in a wooded area of central New York will stretch into a third day Monday.
Frank and Evelyn Amerosa of Utica, N.Y., were aboard an Angel Flight on Friday night when the twin-engine aircraft went down in Ephratah, a sleepy town about an hour west of Albany, according to police and family members.
Officials and family said John Campbell, 70, of Stamford, Conn., was flying the couple back from the Boston area, where Frank Amerosa was being treated for brain cancer.
The bodies of Campbell and Evelyn Amerosa have been recovered from the rural crash site. Dozens of searchers, including a helicopter crew, continued searching the woods and water Sunday for 64-year-old Frank Amerosa, who was presumed dead, said Sgt. Brian Van Nostrand of the Fulton County Sheriff's Department.
Frank Amerosa, a retired trucker, had been diagnosed with brain cancer more than a year ago. Evelyn Amerosa, 58, worked at an area nursing home directing residents in activities like bingo and trips ? a job she loved, said her daughter Heather Theobald. She said her mother had been with her step-father for at least 16 years. The couple loved to travel and had recently returned from the Bahamas.
"Very happy, very much love, very optimistic, they did everything for anybody," Theobald told The Associated Press. "They were just very good people. They were loved by a lot of people."
Campbell was a volunteer pilot for Angel Flight, a nonprofit group that arranges free air transportation for the sick. Angel Flight Northeast said it has set up free air transportation and medical care for more than 65,000 children and adults on about 60,000 flights covering more than 12 million miles. It was founded in 1996.
"John loved to fly and truly believed in the mission of Angel Flight. He loved volunteering his time and we take some solace in the fact he died doing something he loved while trying to help others," according to a family statement read to the AP by his daughter Kimberly Conti, of Rutherford, N.J.
Rescue workers on Sunday scoured the woods and searched a big, murky pond where the bulk of the aircraft was submerged. Wreckage from the crash was dispersed over a large area, with pieces of the plane found as far as five miles away.
National Transportation Safety Board investigators who returned to the crash site Sunday aim to retrieve the bulk of the wreckage from the water over the next few days, said agency spokesman Eric Weiss. They are looking for smartphones, GPS devices, computer tablets or other items that could "give the investigators some electronic evidence of what happened in the last minutes of flight," he said.
The Piper PA 34 had departed from Hanscom Field in Bedford, Mass., and was headed to Rome, N.Y., before it crashed just after 5 p.m. Friday, Federal Aviation Administration spokeswoman Kathleen Bergen said. The plane did not issue a distress call before losing radar and radio contact, the NTSB said.
Terence Kindlon, an Albany attorney who is a volunteer pilot for Angel Flight, said he and another lawyer, Dale Thuillez, had flown the couple to Boston on Friday morning in Thuillez's plane. He quickly found out he had something in common with Frank Amerosa.
"We were both former Marines and had been in Vietnam pretty close together in time," Kindlon said. "We hit it right off. He was a nice guy."
The two lawyers flew back to Albany in Thuillez's plane after dropping off the couple in Boston.
While the cause of the crash remains under investigation, Kindlon stressed that "the standards for being an Angel Flight pilot are rigorous."
Authorities had initially said the bodies of two passengers were found after the aircraft went down Friday night. But Van Nostrand corrected that report Sunday, saying the bodies of the Evelyn Amerosa and Campbell had been found.
Witnesses described the destruction that started in the air above Ephratah.
Joan Dudley, owner of Granny's Ice Cream Shanty, which is less than a mile from the crash site, said she and her employees saw the plane flip, then fall apart Friday night.
"Parts and pieces of it were flying through the sky, and a body fell out," Dudley said.
They called 911 as they parked their car and ran to the crash site in the rain to see if they could rescue anyone.
"Airplane parts were all over the place," she said. "They were picking them up all over."
Ephratah resident Roger Berry, 75, said he was outside chopping wood when the plane crashed.
"When I heard it, I knew something was wrong," Berry said.
Berry said he heard a bang, then saw pieces of the plane fall from the sky. The motor fell 50 feet from his neighbor's bedroom, where she was sleeping, Berry said.

The so-called "Hot Dog Hooker' was boiling mad at her recent court appearance after being arrested again for alleged prostitution.
Catherine Scalia, 47, earned her moniker after she was arrested in 2012 for allegedly selling more than just hot dogs out of her food truck in Long Island, N.Y. At her arraignment on Saturday, Scalia unleashed an angry tirade against police for targeting her, according to the New York Post.
?They keep framing me!? she told Judge Colin O?Donnell. ?There was no money exchanged! I did it for free. I?m broke, I?m jobless.?
Scalia's bail was set at $10,000.
MyFox New York reports that Scalia allegedly, "drove her vending truck to a hotel in East Garden City on Friday where she offered to engage in a sexual act with an undercover officer."
The amount of money purportedly agreed to was not disclosed, according to the station.
Scalia was arrested in May last year and pleaded guilty to prostitution charges, CBS New York reports. Despite her plea, she insisted she was just stripping for men as well as selling hot dogs.
?To the mothers and children out there, I will be selling the hot dogs in my bikini," Scalia said at the time of her 2012 arrest. "To all the guys, I?m gonna wiggle those weiners, we?re gonna have a good time."

Ah, there's nothing like using a car sticker to let the whole neighborhood know you're single again.
Just take a look at the decal Redditor Grant291's neighbor displayed on her car recently. We think it gets the point across just fine.
The disembodied hands? We don't even know.
Tell us what you think of this post-split stick figure family below, then click through the slideshow below for more bad bumper stickers from around the web.
But for WHO?
Is this a warning or a celebration?
There's such a thing as too much honesty.
While we are also partial to cats, we do NOT want to meet the owner of this car.
Probably all of us.
Pick a side, friend.
Seriously, WTF?
What about Mark Harmon??? We will never know!
It's both pessimistic and a corny pun. Barf.
While flipping the script on the hot lady bumper sticker is appreciated, still... gross.
Ohhhh, we get what you did there.
That's just depressing.
On second thought, maybe this is the most awesome bumper sticker.
