IRS review of Tea Party scrutiny in 2012 found bias: U.S. Republicans

By Kim Dixon

WASHINGTON (Reuters) - The U.S. Internal Revenue Service in 2012 reviewed allegations that conservative Tea Party groups had come under extra scrutiny by the tax service's agents and found bias against conservatives, Republican members of Congress said on Tuesday.

"At no point did you or anyone else at IRS inform Congress of the results of these findings," Republican Darrell Issa, chairman of the House of Representatives Oversight and Government Reform Committee, wrote in a letter to Lois Lerner, the head of the IRS' tax exempt organizations unit.

Lerner publicly apologized about the extra scrutiny on Friday at a conference, setting off a storm of controversy.

Republicans probing the IRS scrutiny said the tax agency's officials informed them of the 2012 review in a meeting on Monday.

IRS officials also told Republicans that 471 groups had been placed under additional scrutiny as part of the agency's process, Issa said, citing the meeting.

"It is unclear whether conservative and Tea Party groups are continuing to be targeted even today," Issa said in the letter.

Issa, whose committee has subpoena power, requested a list of documents from the IRS related to his panel's probe.

The U.S. Treasury's Inspector General for Tax Administration is expected soon to issue a report on the allegations of bias against conservatives.

Turkey: 9 detained in connection with car bombings

REYHANLI, Turkey (AP) ? Turkey's interior minister says authorities have detained nine people in connection with the car bomb attacks that killed 46 people in a Turkish town near the Syrian border.

Muammer Guler says the attacks were carried out by a group linked to Syria's intelligence service, but did not name the group.

Syria on Sunday rejected Turkey's allegations that it was behind the bombs.

Guler said authorities had so far identified 35 people who died in the attack and three of them were Syrians.

Artists of the Week: Southern chapter of the New Mexico Watercolor ...

LAS CRUCES ? The southern chapter of the New Mexico Watercolor Society celebrates a milestone this month with "A Round Dozen: 12 Years of Service to Artists in Southern New Mexico," a new show featuring members' works at the Branigan Cultural Center.

"A nucleus of charter members drew up bylaws in 2001 and started the chapter in Las Cruces as an addition to the original chapter in Albuquerque. Since that time, we have grown into a premier group with three exhibitions each year: one in the spring, one in the fall, and our annual For Love of Art Month themed small works show in February," said member Mayanna Howard.

"Many of the watercolorists whose work was juried into this show are award-winning artists. Some are signature members of the New Mexico Watercolor Society, meaning they have been accepted into juried NMWS exhibits at least five times in the past," Howard said, adding that featured works, "will demonstrate the fine techniques of watercolor employed by the nearly 100 members of the society."

The ephemeral immediacy of watercolor, which some artists consider the most difficult and unforgiving medium, continues to have an irresistible appeal for many painters.

"I'm a control freak and watercolor won't let me do that," said Jan Addy, who enjoys the freedom the medium encourages. "I love the looseness and the way colors mix on the paper. I can get totally lost, look up and realize two hours have gone by."

Addy, a society member since 2004, said

membership means a lot to her "because I haven't painted all of my life. It's a wonderful place to be challenged and learn new things. The group is very supportive. And monthly programs with demonstrations, discussions or talks by seasoned artists give me new abilities. It's about continuing to learn."

The juried spring exhibit features several noted regional artists, including Lu Bleveans, Pat Bonneau-White, Penny Duncklee, Sue Ann Glenn, Jan Addy, Mayanna Howard, Barbara Kejr, Gail Makowsky, Beverley Pirtle, Marie Siegrist, Penny Thomas Simpson, Dave Sorensen, Lynne Souza, Arlene Tugel, Laurel Weathersbee, Donna Wood and Phil Yost.

The group meets at 2 p.m. the second Sunday of each month, September through May, at the Activities Room at Good Samaritan, 3025 Terrace Drive. The exception will be this month, when, because the regular meeting date falls on Mother's Day, the group will meet at 2 p.m. May 19. Beverley Pirtle will present a talk about influential 19th century British watercolorist J.M.W. Turner. The meeting will also include a "Swap & Sell" of art supplies, books and DVDs.

"Our meeting are open to everyone interested in watercolor paining and anyone interested in getting some things inexpensively is welcome. Several artists from the Southern Chapter have volunteered to work with the New America School art club, offering demonstrations and introducing them to the NMWS. Because these students have very limited art resources, contributed supplies (part of the Swap & Sell) will be donated to the school for art club use," Addy said.

The society's 2013 spring show will run through May 25 at the Branigan Cultural Center, 501 N. Main St. Regular gallery hours are 10 a.m. to 4 p.m. Monday through Friday. Their fall show at the New Mexico Farm & Ranch Heritage Museum will run Aug. 16 through Dec. 1, with an artists' reception Sept. 19.

Drug manufacturer agrees to $500 million penalty

(AP) ? A subsidiary of an Indian pharmaceutical company has agreed to pay $500 million fines and civil penalties for selling adulterated drugs and lying about tests to federal regulators, the Justice Department said Monday.

The guilty plea by Ranbaxy USA Inc. represents the largest financial penalty by a generic drug company for violations of the Federal Food, Drug and Cosmetic Act, which prohibits the sale of impure drugs, prosecutors said.

Ranbaxy, a subsidiary of Ranbaxy Laboratories Limited, admitted that it made and sold impure drugs at two manufacturing sites in India. The batches of adulterated drugs included generic versions of an antibiotic and other medications used to treat severe acne, epilepsy and nerve pain.

The company agreed to a fine and forfeiture of $150 million as well as an additional $350 million penalty to settle civil claims that it submitted false statements to Medicaid, Medicare and other government health care programs.

The company also admitted making false statements to the Food and Drug Administration about dates of stability testing, which detect impurities of a drug and to determinate appropriate storage conditions of it.

10 Little Things That Would Make Time Travel Super Annoying

The first problems that come to mind when you think about time travel probably involve the fabric of the universe or the state of your own existence. But those aren't what would make time travel just plain old irritating. Glove and Boots came up with a little list, and you'll wonder how you never considered them. Maybe blowing up the universe isn't so bad. [Glove and Boots via Laughing Squid]

NBC hopes Hayes, Fox can bolster Thursdays

NEW YORK (AP) ? NBC will try to awaken the ghosts of past dominance on Thursday night by making it a "family night" of television bolstered by the additions of Sean Hayes and Michael J. Fox.

NBC on Sunday became the first of the major broadcasters to announce its plans for next season, and its executives said they had ordered a staggering 17 new series. Only six of them are on fall's schedule, however, with another six to join in midseason when NBC hopes to get a burst of attention from its telecast of the Winter Olympics.

The struggling network is also taking a risk by moving two of its young and promising dramas to new nights: "Revolution" will switch from Monday to Wednesday, and "Chicago Fire" from Wednesday to Tuesday.

After an encouraging start to the current season last fall behind Sunday Night Football and "The Voice," the bottom fell out in midwinter when those two shows went away. NBC had some historically bad ratings, even falling behind the Spanish-speaking Univision in the February sweeps. Its executives were not made available to speak about the plans on Sunday.

Thursday used to be "must-see TV" on NBC in the 1990s but its decline symbolized the network's troubles. NBC's new emphasis for Thursday will be on broader-based, family comedies instead of shows like "The Office" which was a hit with critics but not the audience.

NBC will seek a turnaround with "Sean Saves the World," starring Hayes as a divorced gay dad who juggles work with raising a teenage daughter. Fox's show mirrors his life ? he plays a character getting back to work after being diagnosed with Parkinson's Disease. The third new Thursday comedy is "Welcome to the Family," about a white high school graduate impregnated by her Latino boyfriend.

Amy Poehler's "Parks and Recreation" will be back to open NBC's Thursday schedule. The network announced that the quirky "Community" had been renewed, but it hasn't found a spot on the schedule yet.

The drama "Parenthood" will air Thursday at 10 p.m.

NBC has canceled several of its shows, including the newsmagazine "Rock Center," the Matthew Perry comedy "Go On" and the quickly forgotten comedies "The New Normal," ''Up All Night," ''Guys With Kids," ''1600 Penn" and "Whitney."

The network said no decision has been made on the future of the low-rated serial killer drama "Hannibal" or the durable Donald Trump game "Celebrity Apprentice."

New fall dramas include "The Blacklist," which stars James Spader as fugitive who volunteers to help the FBI catch a terrorist; and "Ironside," with Blair Underwood as a New York City detective who uses a wheelchair.

NBC said two new comedies will replace "The Biggest Loser" on Tuesdays in midseason. And when football goes away, the network will try two new dramas on Sunday nights: "Believe," a J.J. Abrams series about a girl coming to grips with superpowers, and "Crisis," about a bus full of children of Washington elite who are kidnapped.

Extraordinary 28-Hour Dubai Timelapse Makes The World Seem Magical

Back in 2011 when Gerald Donovan filmed Dubai for 28 hours he made an incredible timelapse of it. But he couldn't leave well enough alone. After the limitless potential of the footage nagged at him for a few years he came back to it and made another beautiful version.

This time it spans all 28 hours instead of 24 and runs at 30fps with improved white balance. The new version calls more purposeful attention to light and shadow, movement of cars and people, and changes in the sky. It's a pretty amazing vantage point for viewing the city.

Sharp reportedly laying off 5,000 employees, focusing more on smartphone displays and bigger, better TVs for US market

Sharp reportedly firing 5,000 employees, narrowing focus on smartphone displays

Sharp finally had something positive to report a couple of months ago when it received a much-need cash injection from Samsung, but today's news isn't so rosy. According to The Asahi Shimbun, Sharp will reveal a three-year management plan next Tuesday that'll see 5,000 workers losing their jobs as part of the company's efforts to claw its way back into the black. Many of those who are expected to be axed are said to be employed outside of Japan, but the number of empty desks at Sharp's head office in Osaka is also set to increase -- half of the workforce there will be sent on their way, including half of the company's directors. Allegedly, Sharp will also begin producing more 4K sets and 70-inch or over HDTVs for the US market, and also shift its broader focus towards making more "small-sized panels for smartphones and other devices." Who exactly are these displays being made for, we wonder?

Menendez Pushing for Halt To Flood Insurance Rate Hikes ...

U.S. Senator Bob Menendez threw Shore residents a virtual lifeline Thursday, delivering an address on the Senate floor where he urged colleagues to support an amendment to federal legislation that would stop flood insurance rate hikes, at least in the short term.

Menendez (D-N.J.) spoke in favor of an amendment to the Water Resources Development Act which would stop flood insurance premiums from rising until FEMA completes its study on the affordability of premiums of the National Flood Insurance Program.

Shore homeowners face annual flood insurance premiums of up to $31,000 a year if they do not raise their homes at a significant cost. Many homeowners who were never previously located in flood zones now find themselves being listed as living in flood-prone areas with a requirement to buy the insurance to maintain their mortgages.

Menendez said New Jersey residents have come to him in tears, saying they are afraid they may lose their homes.

"These are hard-working middle-class families who have played by the rules, purchased flood insurance responsibly, and now are being priced out of the only home in which they have ever lived," he said. "This amendment would delay these potentially devastating changes until FEMA completes its study on premium affordability."

Federal legislation passed last year requires FEMA to conduct an affordability study, but ten months later, the study has not been conducted. The ammendment favored by Menendez would require that study to be conducted before any rate hikes could take place.

"It is like a triple whammy," Menendez said. "We have the consequences of Superstorm Sandy, which devastated homes, so they have to rebuild. Many times, that insurance didn't rise to the level of the cost of rebuilding. Secondly, and as a result of flood maps that came in after the storm, there are now requirements for new elevations. Thirdly, the premiums are going to skyrocket because the subsidies go down. So we have a triple whammy."

Paul Brubaker, Menendez' press secretary, said the senator has also been pushing for vouchers to be made available to help homeowners afford flood insurance policies.

(AP) ? For 17 days, the seamstress lay trapped in a dark basement pocket beneath thousands of tons of wreckage as temperatures outside climbed into the mid-90s F. She rationed food and water. She banged a pipe to attract attention. She was fast losing hope of ever making it out alive.

In the ruins of the collapsed eight-store garment factory building above her, the frantic rescue operation had long ago ended. It had turned instead into a grim search for the decaying bodies of the more than 1,000 people killed in the world's worst garment industry disaster.

"No one heard me. It was so bad for me. I never dreamed I'd see the daylight again," the seamstress, Reshma Begum, told Somoy TV from her hospital bed after her astonishing rescue on Friday.

The miraculous moment came when salvage workers finally heard Begum's banging. They pulled her to safety. She was in shockingly good condition, wearing a violet outfit with a large, bright pink scarf.

"I heard her say, 'I am alive, please save me.' I gave her water. She was OK," said Miraj Hossain, a volunteer who crawled through the debris to help cut Begum free.

The rescue was broadcast on television across Bangladesh. The prime minister rushed to the hospital, as did the woman's family to embrace a loved one they thought they'd never again see alive.

On April 24, Begum was working in a factory on the second floor of Rana Plaza when the building began collapsing around her. She said she raced down a stairwell into the basement, where she became trapped near a Muslim prayer room in a wide pocket that allowed her to survive.

Her long hair got stuck under the rubble, but she used sharp objects to cut her hair and free herself, said Maj. Gen. Chowdhury Hasan Suhrawardy, the head of the local military units in charge of the disaster site.

"There was some dried food around me. I ate the dried food for 15 days. The last two days I had nothing but water. I used to drink only a limited quantity of water to save it. I had some bottles of water around me," Begum told the television station, as doctors and nurses milled about, giving her saline and checking her condition.

More than 2,500 people were rescued in the immediate aftermath of the disaster, but crews had gone nearly two weeks without discovering anyone alive. The last survivor had been found April 28, and even her story ended tragically. As workers tried to free Shahina Akter, a fire broke out and she died of smoke inhalation.

Crews were instead engaged in the painstaking work of trying to remove bodies so the victims' families could bury their loved ones. They eventually approached the section where Begum was trapped.

"I heard voices of the rescue workers for the past several days. I kept hitting the wreckage with sticks and rods just to attract their attention," Begum said.

She finally got the crews' attention when she took a steel pipe and began banging it, said Abdur Razzak, a warrant officer with the military's engineering department who first spotted her in the wreckage.

The rescue crews could not believe there might be a survivor. "But within minutes, we were sure that there was someone," Razzak said.

The workers ran into the dark rubble, eventually getting flashlights, to free her, he said.

They ordered the cranes and bulldozers to stop immediately and used handsaws and welding and drilling equipment to cut through the iron rod and debris still trapping her. They gave her water, oxygen and saline as they worked.

Hundreds of people engaged in removing bodies from the site in recent days raised their hands together in prayer for her survival.

"God, you are the greatest, you can do anything. Please allow us all to rescue the survivor just found," said a man on a loudspeaker leading the supplicants. "We seek apology for our sins. Please pardon us, pardon the person found alive."

After 40 minutes, she was free.

"When we were able to reach there, we lifted her together with our hands and brought her out to put her on a stretcher. She was baffled as rescuers outside shouted 'God is great,'" said Hossain, one of her rescuers.

Soldiers and men in hard hats carried Begum on a stretcher to a waiting ambulance, which brought her to a military hospital. Her rescuers said she was in good condition, despite her ordeal. Razzak said she could even walk.

"She was fine, no injuries. She was just trapped. The space was wide," said Lt. Col. Moyeen, an army official at the scene who uses only one name.

Doctors at the hospital told Bangladeshi television that Begum was out of danger and that her kidney and liver function were fine.

Begum survived for more than two weeks in temperatures that touched the mid-30s C (mid-90s F).

"This is just a miracle, this is so pleasing!" said Razzak, the warrant officer.

Begum told her rescuers there were no more survivors in her area. Workers began tearing through the nearby rubble anyway, hoping to find another person alive.

"Reshma told me there were three others with her. They died. She did not see anybody else alive there," said Maj. Gen. Chowdhury Hasan Suhrawardy, the head of the local military units. The bodies were eventually recovered from another section of the building not far from Begum, he said.

Begum's sister Asma said she and her mother kept a vigil for the seamstress, who is from the rural Dinajpur district, 270 kilometers (170 miles) north of Dhaka. She said they had been losing hope amid the endless string of grim days, when scores of bodies and no survivors were removed from the rubble.

"We got her back just when we had lost all our hope to find her alive," she told Somoy TV. "God is so merciful."

The women rushed to the hospital to see her.

Prime Minister Sheikh Hasina called Begum in the hospital, and the rescued woman began crying on the phone, Suhrawardy said. She told Hasina: "I am fine, please pray for me," he said.

Hasina, whose government has come under criticism for its lax oversight over the powerful garment industry, raced to the hospital by helicopter to meet her and congratulated the rescuers, officials said.

"This is an unbelievable feat," Hasina was quoted as saying by her assistant, Mahbubul Haque Shakil.

Begum lived in a rented house in this Dhaka suburb with her sister, who worked at a different garment factory

The death toll from the disaster soared past 1,000 on Friday, with officials confirming that 1,045 bodies had been recovered from the ruins of the fallen building, which had housed five garment factories employing thousands of workers.

The disaster has raised alarm about the often deadly working conditions in Bangladesh's $20 billion garment industry, which provides clothing for major retailers around the globe.

Brig. Gen. Mohammed Siddiqul Alam Shikder, an army official overseeing the recovery work, said the bodies being recovered were badly decomposed and identification was difficult.

"We are working carefully," he said. "If we get any ID card or mobile phone with them, we can still identify them. Our sincere effort is to at least hand over the bodies to the families."

Brig. Gen. Azmal Kabir, a top official of the military's engineering section, said more than half of the estimated 7,000 tons of debris have been removed from the site but he did not know when the work would be finished.

Officials say the owner of Rana Plaza illegally added three floors and allowed the garment factories to install heavy machines and generators, even though the structure was not designed to support such equipment.

The owner and eight other people, including the owners of the garment factories, have been detained.

How individuality develops: Experience leads to growth of new brain cells

May 9, 2013 ? The adult brain continues to grow with the challenges that it faces; its changes are linked to the development of personality and behavior. But what is the link between individual experience and brain structure? Why do identical twins not resemble each other perfectly even when they grew up together? To shed light on these questions, the scientists observed forty genetically identical mice that were kept in an enclosure offering a large variety of activity and exploration options.

"The animals were not only genetically identical, they were also living in the same environment," explains principal investigator Gerd Kempermann, Professor for Genomics of Regeneration, CRTD, and Site Speaker of the DZNE in Dresden. "However, this environment was so rich that each mouse gathered its own individual experiences in it. Over time, the animals therefore increasingly differed in their realm of experience and behavior."

The DFG-Center for Regenerative Therapies Dresden -- Cluster of Excellence at the TU Dresden (CRTD), the Dresden site of the German Center for Neurodegenerative Diseases (DZNE), and the Max Planck Institute for Human Development in Berlin played a pivotal role in the study.

New neurons for individualized brains

Each of the mice was equipped with a special micro-chip emitting electromagnetic signals. This allowed the scientists to construct the mice's movement profiles and to quantify their exploratory behavior. The result: Despite a common environment and identical genes the mice showed highly individualized behavioral patterns. They reacted to their environment differently. In the course of the three-month experiment these differences increased in size.

"Though the animals shared the same life space, they increasingly differed in their activity levels. These differences were associated with differences in the generation of new neurons in the hippocampus, a region of the brain that supports learning and memory," says Kempermann. "Animals that explored the environment to a greater degree also grew more new neurons than animals that were more passive."

Adult neurogenesis, that is, the generation of new neurons in the hippocampus, allows the brain to react to new information flexibly. With this study, the authors show for the first time that personal experiences and ensuing behavior contribute to the ?individualization of the brain." The individualization they observed cannot be reduced to differences in environment or genetic makeup.

?Adult neurogenesis also occurs in the hippocampus of humans," says Kempermann. "Hence we assume that we have tracked down a neurobiological foundation for individuality that also applies to humans."

Impulses for discussion across disciplines

?The finding that behavior and experience contribute to differences between individuals has implications for debates in psychology, education science, biology, and medicine," states Prof. Ulman Lindenberger, Director of the Center for Lifespan Psychology at the Max Planck Institute for Human Development (MPIB) in Berlin. "Our findings show that development itself contributes to differences in adult behavior. This is what many have assumed, but now there is direct neurobiological evidence in support of this claim. Our results suggest that experience influences the aging of the human mind."

In the study, a control group of animals housed in a relatively unattractive enclosure was also examined; on average, neurogenesis in these animals was lower than in the experimental mice. ?When viewed from educational and psychological perspectives, the results of our experiment suggest that an enriched environment fosters the development of individuality," comments Lindenberger.

Interdisciplinary teamwork

The study is also an example of multidisciplinary cooperation -- it was made possible because neuroscientists, ethologists, computer scientists, and developmental psychologists collaborated closely in designing the experimental set-up and applying new data analysis methods. Biologist Julia Freund from the CRTD Dresden and computer scientist Dr. Andreas Brandmaier from the MPIB in Berlin share first authorship on the article. In addition to the DZNE, CRTD, and the MPIB, the German Research Center for Artificial Intelligence in Saarbr?cken and the Institute for Geoinformatics and the Department of Behavioural Biology at the University of M?nster were also involved in this project.

Graphene quantum dots may someday tell if it will rain on Mars

May 8, 2013 ? The latest research from a Kansas State University chemical engineer may help improve humidity and pressure sensors, particularly those used in outer space.

Vikas Berry, William H. Honstead professor of chemical engineering, and his research team are using graphene quantum dots to improve sensing devices in a twofold project. The first part involves producing the graphene quantum dots, which are ultrasmall pieces of graphene. Graphene is a single-atom thick sheet of carbon atoms and has superior electrical, mechanical and optical properties. The second part of the project involves incorporating these quantum dots into electron-tunneling based sensing devices.

To create the graphene quantum dots, the researchers used nanoscale cutting of graphite to produce graphene nanoribbons. T.S. Sreeprasad, a postdoctoral researcher in Berry's group, chemically cleaved these ribbons into 100 nanometers lateral dimensions.

The scientists assembled the quantum dots into a network on a hydroscopic microfiber that was attached to electrodes on its two sides. They placed the assembled quantum dots less than a nanometer apart so they were not completely connected. The assembling of dots is similar to a corn on the cob structure -- the corn kernels are nanoscale quantum dots and the cob is the microfiber.

Several researchers -- including four 2012 alumni in chemical engineering: Augustus Graham, Alfredo A. Rodriguez, Jonathan Colston and Evgeniy Shishkin -- applied a potential across the fiber and controlled the distance between the quantum dots by adjusting the local humidity, which changes the current flowing through the dots.

"If you reduce the humidity around this device, the water held by this fiber is lost," Berry said. "As a result, the fiber shrinks and the graphenic components residing atop come close to one another in nanometer scale. This increases the electron transport from one dot to the next. Just by reading the currents one can tell the humidity in the environment."

Decreasing the distance between the graphene quantum dots by 0.35 nanometers increased the device's conductivity by 43-fold, Berry said. Furthermore, because air contains water, reducing air pressure decreased its water content and caused the graphene quantum dots to get closer together, which increased conductivity. Quantum mechanics suggests that electrons have a finite probability to tunnel from an electrode to a nonconnected electrode, Berry said. This probability is inversely and exponentially proportional to the tunneling distance, or the gap between the electrodes.

The research has numerous applications, particularly in improving sensors for humidity, pressure or temperature.

"These devices are unique because, unlike most humidity sensors, these are more responsive in vacuum," Berry said. "For example, these devices can be incorporated into space shuttles, where low humidity measurements are required. These sensors might also be able to detect trace amounts of water on Mars, which has 1/100th of Earth's atmospheric pressure. This is because the device measures humidity at a much higher resolution in vacuum."

While the heart of the device is the modulation of electron tunneling, the response of the device is through the polymer microfiber, Berry said. His team also is looking at changing the polymer to find other applications for this research.

"If you replace this polymer with a polymer that is responsive to other stimuli, you can make a different kind of sensor," Berry said. "I envision this project to have a broad impact on sensing."

The research is supported by Berry's five-year, $400,000 National Science Foundation CAREER award. The research results appear in a recent issue of the journal Nano Letters in an article titled "Electron-tunneling modulation in percolating-network of graphene quantum dots: fabrication, phenomenological understanding, and humidity/pressure sensing applications."

The research is dedicated to Vasanta Pallem, a postdoctoral researcher who was involved in the work and died in a recent apartment fire.

Berry's research team also is studying molecular machines interfaced with graphene. In this work, the researchers are able to mechanically actuate the molecules, which undergo a change in the electric field around them and influence the carrier density of the interfaced graphene. This work will appear in an upcoming issue of the journal Small in an article titled "Covalent functionalization of dipole-modulating molecules on trilayer graphene: an avenue for graphene-interfaced molecular machines."

The researchers have found that graphene responds sensitively to molecular motion. Phong Nguyen, a doctoral student in chemical engineering and lead author of the work, tethered actuating molecules on graphene and measured the device's response.

"The next phase of science beyond nanotechnology will be molecular technology," Berry said. "We are working on developing routes to incorporate molecular machines into devices."

Biosensor that detects antibiotic resistance brings us one step closer to fighting superbugs

May 8, 2013 ? On May 8th JoVE will publish research that demonstrates how a biosensor can detect antibiotic resistance in bacteria. This new technology is a preliminary step in identifying and fighting superbugs, a major public health concern that has led to more deaths than AIDS in the United States in recent years.

The technology is the result of collaboration between Dr. Vitaly Vodyanoy at Auburn University and the Keesler Air Force Base with funding from the United States Air Force.

Louis Pasteur and Robert Koch first characterized antibiosis, the ability for a chemical to kill bacterial cells, in 1877. Since then, the medical and biochemical communities have made great advances in the treatment of bacterial infections. These advances have helped reduce childhood mortality and have contributed to the population growth of the 20th Century. However, natural selection has allowed antibiotic resistant bacteria to flourish and propagate, and continued exposure has lead to the evolution of "superbugs" that are resistant to multiple types of antibiotics.

"Antibiotic resistant bacteria is a serious problem," Dr. Vodyanoy says. "It is very important [when treating a patient] to distinguish between normal and resistant bacteria; if you have a case of resistance you have to take special measures to cure it."

Dr. Vodyanoy's technology takes advantage of bacteriophages, simple viruses that can target and kill bacteria. A bacteriophage, when combined with specific antibodies, can be used to produce a physical color change in a sample that indicates antibiotic resistance. This technology will be invaluable to clinicians trying to treat patients and disinfect hospital facilities.

Specifically, this technique targets antibiotic resistant Staphylococcus, one of the first pathogens characterized as a superbug. Staphylococcus, commonly referred to as staph, often is a bothersome skin condition cured with common antibiotics. However, variations of the staph bacteria can turn deadly when infecting immune-compromised patients or internal organs like lungs and the respiratory tract. The disease is of particular concern to hospitals, prisons, and branches of the military, where individuals are at risk for infection from unhygienic close quarters.

"In our method, we can determine bacterial antibiotic resistance in 10-12 minutes, while other methods take hours," Dr. Vodyanoy explains. Alternative methods used to detect antibiotic resistance need time-intensive purification steps before multi-hour sequencing protocols. "We envision a future where clinicians do tests with real blood or saliva samples. The virus is completely benign to humans, and we hope to use it to make antimicrobial surfaces and glassware that kill the bacteria."

This week's sidebar poll: Where do you store your contacts?

contacts

Keeping track of the names and numbers can be quite the task. How do you tackle it?

Your contacts, and keeping the list of them safe and sound, is a pretty big deal for some of us. I've got a couple thousand, and that's after paring things down to just the people I might want to get in touch with one day. I'm sure a lot of you have even more. 

A smart phone is a convenient place and method to keep track of them all. And, just like everything else, there are several different places to store them. Most of us here will probably use Google to store the email addresses and phone numbers of the people we want to talk to, but that's certainly not a requirement. You can store all that data on your phone's memory, or even on your SIM card -- provided you keep the number reasonable.

So, we're curious. Tell us where you keep your contacts, and be sure to hit the comments to tell us why, or any interesting tales of woe that you may have. There's a poll over to the right, and you can also find it after the break. Let us know!

A quick look at last week's poll results:

What's your Android keyboard of choice?

Android Central

SwiftKey is the big winner, with more users than the rest combined. We understand why, because that word prediction is so good it's scary!

Soldier says she faced harassment over Muslim name

Sgt. 1st Class Naida Nova is shown in this undated U.S. Army photo provided by Sgt. Nova. With her family name emblazoned on her uniform, Sgt. Nadia Hosan says she was routinely the target of derogatory remarks from other soldiers who mistakenly assumed she is a Muslim. So before deploying for her second war tour, the life-long Catholic legally changed her name to Nadia Christian Nova. The 82nd Airborne, who in a federal lawsuit she claims branded her a ?Muslim sympathizer,? revoked her security clearance and tried to force her out of the Army with a less than honorable discharge.

(AP Photo/US Army)

RALEIGH, N.C. (AP) ? Sgt. 1st Class Naida Hosan is not a Muslim ? she's a Catholic. But her name sounded Islamic to fellow U.S. soldiers in Iraq, and they would taunt her, calling her "Sgt. Hussein" and asking what God she prayed to.

So before deploying to Afghanistan last year for her second war tour, she legally changed her name ? to Naida Christian Nova.

This did not solve her problems.

Instead, matters escalated. Nova complained to her superiors about constant anti-Muslim slurs and jokes. She says they responded with a series of reprisals intended to drive her out of the Army, leading her to consider suicide.

"My complaints fell on deaf ears every time," said Nova, 41, a member of the Army's 82nd Airborne Division based at Fort Bragg, N.C. "Any time I would say something about it I was treated like I didn't know what I was talking about or that I'm an idiot or that I was a Muslim sympathizer. It was just a very lonely feeling."

Determined to remain in the service for at least eight years, until she is eligible for retirement, Nova recently re-enlisted. But she agreed to tell her story to The Associated Press because "I don't want this to happen to anyone else if I can help it. It's a horrible to feel like people are against you when you are supposed to be on the same team."

Fort Bragg spokeswoman Sheri L. Crowe said the Army would not comment on the case, and referred questions to the U.S. Department of Justice. The U.S. Attorney's Office for the Eastern District of North Carolina, assigned to defend the Army, also declined comment.

But her account is supported by an affidavit filed by an old friend, Sharon Deborah Sheetz, who said that Nova had confided in her about the harassment she had suffered, telling Sheetz that she was so unhappy that she no longer wanted to live.

A Farsi linguist who works in military intelligence, Nova's multicultural background exemplifies the kind of soldier Army recruiters prize ? U.S. citizens with ethnic ties to a part of the world many Americans can't find on a map.

Nova's father, Roy Hosein, was born into a Muslim family on the Caribbean island of Trinadad, where his parents had emigrated from India. He converted to Christianity after meeting Nova's mother, a Catholic from the Philippines, and became a U.S. citizen shortly after his daughter was born in New York. He changed the spelling of his family name to Hosan in the hope his children would avoid discrimination.

"He Americanized it," his daughter explained. "He got Hosan from Hosanna. He kept hearing it in church."

She reported for basic training two months after the terrorist attacks on Sept. 11, 2001.

"Before 9-11, my last name never raised an eyebrow," she said. "But after 9-11, I felt compelled to tell people I am a Christian and felt I had to prove I was loyal to the United States."

Her first deployment was to Iraq in 2005. She said other soldiers, including her supervisors, mocked her family name and made crude jokes.

"I was called Sgt. Hussein, as in Saddam Hussein," she said. "Even when I would correct them on the pronunciation of my name, I was still called Sgt. Hussein. I was asked what God I pray to. And there were a lot of references to hajjis, used as a derogatory term."

Hajiis, in fact, are Muslims who have made the pilgrimage to the Saudi Arabian birthplace of the prophet Muhammad. But Nova said she regularly heard U.S. troops use the word as racist slang for enemy, terrorist or suicide bomber.

"My uncle is a hajji, because he made the pilgrimage to Mecca in 2005," Nova said. "I would stand up for what I thought was right and say, 'Not all terrorists are Muslims and not all Muslims are terrorists.' That just opened the door for more harassment."

Mikey Weinstein, a former U.S. Air Force officer who founded Military Religious Freedom Foundation, said Nova's experience is not uncommon. Military personnel who are Muslim or perceived to be of Middle Eastern descent are often targets for discrimination, he said.

"When a Muslim soldier, sailor or airman stands up for themselves, they are the subject of vicious reprisal and retribution," said Weinstein, who is Jewish. "What (Sgt. Nova) has gone through is horrible, but it is typical."

In 2007, while serving in Harrogate, England, Nova said co-worker told her and others a racist joke about Muslims. When she objected, Nova said, a supervisor warned her to stop making trouble. Instead, she filed a formal complaint with the Army's Equal Opportunity Branch, the program charged with ensuring the military provides an environment "free of unlawful discrimination and offensive behavior."

Within days, Nova said she was removed from her job and ordered to take a "command directed" mental health evaluation.

"In writing, the referral said my values were not in line with mission," she said. "They considered me a 'Muslim sympathizer,' that I was too loyal to Muslims."

Rather than address her complaint, Nova said, the Army transferred her to the 82nd Airborne at Fort Bragg. Though she hoped to make a fresh start with her new unit, word of her complaint followed her to North Carolina.

That treatment worsened after a November 2009 shooting rampage at Fort Hood in Texas. Maj. Nidal Hasan, a Muslim, is charged with killing 13 people. His name sounded a lot like hers.

Nova changed her name shortly before deploying to Afghanistan last year. She arrived just after worn copies of the Quran were found to have been burned with trash from a U.S.-run prison outside the capital of Kabul, a widely reported incident that triggered violent protests.

The Army responded by initiating a new training program on the proper handling and disposal of Islamic materials. But Nova said she discovered that her unit trashed and burned documents collected through intelligence gathering that contained what could be considered sacred writings.

Nova conferred with an on-base military chaplain, and suggested designating a special box for Islamic materials so they could be disposed of in a more appropriate manner.

"When I brought this up, I was told 'Sgt. Nova, you can't bring your religion to work ...,'" she recalled. "I changed my name, but that didn't change other people's ignorance."

After just two months in Afghanistan, she said her commanders removed her from her job and ordered her back to Fort Bragg.

With the help of a Fayetteville lawyer, Mark Waple, she filed a formal complaint with the Army's Inspector General in October seeking a voluntary discharge due to being subjected to "adverse treatment and negative, prejudicial remarks ... concerning the Muslim faith."

Nova said she grew so depressed that she considered suicide. She checked herself into an on-base hospital for treatment, staying for about a week before returning to duty.

After learning of her IG complaint and hospitalization, Nova's commanders at Fort Bragg responded by filing paperwork to involuntarily end her military career and bar her from reenlistment for "ineffective leadership."

Nova's Army performance review from a few months earlier, a copy of which she provided to AP, shows her as meeting expectations in all categories, with her senior commander rating her potential for promotion and increased responsibility as "superior."

The forced discharge could have imperiled Nova's ability to get a civilian job, denied her Veterans Affairs medical care and educational benefits.

After exhausting her administrative options for fighting her case, Waple helped Nova filed a complaint in federal court alleging discriminatory treatment and asking a judge to prevent her discharge.

Rather than fight the case in court, the Army retreated. Shortly before a key hearing before the judge, Waple says he got a call from Army lawyers informing him that the disciplinary action against Nova was "completely off the table." She, in turn, agreed to drop the lawsuit.

Nova re-enlisted in the Army on April 8. She recently married, and is preparing to ship out next month to attend a senior leadership course and then report to a new assignment in Germany.

"I want to put all this behind me. I want to move on to my next duty assignment ...," said Nova. "My beliefs aren't any different from what the Army states as its beliefs and values. I would like to be treated fairly."

Nazi-themed opera creates scandal in Germany

BERLIN (AP) ? A modern production of Richard Wagner's opera "Tannhauser" is causing a stir in Germany because of Nazi-themed scenes showing people dying in gas chambers and members of a family having their heads shaved before being executed.

A spokeswoman for the Dusseldorf opera house said Tuesday that members of the audience "booed and were shocked" by Saturday's opening performance.

Monika Doll said the company of Deutsche Oper am Rhein is debating whether to tone down the provocative parts, added to the original by producer Burkhard Kosminski.

"Members of the audience booed and banged the doors when they left the opera house in protest before the end of the show," the head of the city's Jewish community told The Associated Press on Tuesday. Michael Szentei-Heise called the adaptation at the city's Deutsche Oper am Rhein "tasteless and not legitimate."

The director, Christoph Meyer, said in a statement that the opera company never wanted to hurt the feelings of the viewers. "This is not about mocking the victims, but mourning them," Meyer said.

At the opening of the Duesseldorf performance, performers could be seen inside glass chambers, falling to the floor as white fog flowed ? an allusion to the mass killings of the Jews in the Nazis' death camps. After a half hour, the music stopped and a family stepped on stage. The parents and their children were having their hair shaved off and then they are shot dead ? another reference to treatment of Jewish captives during the Holocaust.

The original Tannhauser opera is set in the Middle Ages and was first performed in Dresden in 1845. It is based on a traditional ballad about the bard Tannhauser and features a singing contest at the Wartburg Castle in south-central Germany.

Szentei-Heise, the Jewish community leader, objected to the inclusion of scenes reminiscent of the Holocaust, which occurred nearly a century after the opera was first performed.

"This opera has nothing to do with the Holocaust," Szentei-Heise said. "However, I think the audience has made this very clear to the opera and the producer."

Wagner, an ardent anti-Semite, remains a controversial figure in Germany and elsewhere nearly 130 years after his death. Adolf Hitler was an admirer, and playing Wagner's music is still considered a taboo in Israel.

The Smarter Way to Sell Your Car

The Fix-Up

A car with serious mechanical flaws is ripe for rejection, or worse, a lowball offer. But even minor problems can give buyers cold feet. Don't pass off "easy fixes" to the next owner?burned-out dashboard lights, chattering wiper blades, and blown-out speakers make you seem inattentive, while cupped tires and illuminated check engine lights signal a potential lemon. Besides, everyone defines (easy) differently: A BMW owner once assured me a leaking heater core was "a simple repair." Was he a rocket scientist who fixed cars in his sleep? I ran screaming from this potential nightmare before I could ask.

If you've modified your car at all, consider bringing it back to stock before selling. (With any luck, your mods are easy to reverse.) Many buyers, including fellow gearheads, see a customized car as a ticking time bomb that has probably seen a lifetime of abuse. Plus, the odds are slim that you'll find a buyer with your taste.

Finally, get a professional oil change and, in states with inspections, a fresh sticker. You may do routine oil changes yourself, and do a fine job every time, but this is about first impressions. A lube-shop windshield reminder inspires more buyer confidence than hand-scrawled masking tape, and clean oil and a new inspection mean fewer post-purchase hassles for the buyer.

The Deep Clean

Naturally, the first step is a fresh wash and wax. Don't forget to clean doorjambs and body seams?drive-through carwashes won't find this grime, but picky buyers will. Pick up a paint restoration kit (about $40) with buffing pads and compounds to polish out light swirls and scratches, and a factory-match touch-up paint pen (usually under $15) for rock chips. A nearly flawless paint job looks great in pictures and in person, and helps justify a top-market asking price.

Inside, vacuum everywhere, including the crevices where pocket change always ends up. That's just the start, and there's no cutting corners: A thorough scrubbing is the only way to erase years of mystery stains and drive-through smells. But avoid the super-shiny dashboard spray and overpowering air fresheners. Both reek of desperation. Follow our checklist for giving your ride a complete cleanup.

Unless your engine compartment is seriously dirty, don't go crazy cleaning up under the hood. A spotless engine makes some buyers suspect undisclosed repairs or hidden leaks, and a mirror shine on working parts can look suspiciously like spray paint. A little road dust won't arouse undue suspicion if everything is in working order.

The Advertising

A professional-looking ad on Craigslist or elsewhere is as important as a well-crafted cover letter. No childish slang, caps-lock, or mangled spelling allowed.

Right up front, state the year, make and model, driveline, and pertinent options, using bullet points to keep things concise. It's best if you can read the entire ad without scrolling. Make sure to disclose any notable issues, like body damage, fluid leaks, or nonfunctional electronic equipment. You don't need to catalog every single scuff or scratch, just anything that falls outside normal wear and tear, or that buyers might note on a test drive. It's the ethical thing to do, and up-front honesty makes buyers more willing to come look at your car. Just save the tearful tale of why you're selling it for your bartender.

Great pictures are the single most effective part of a for-sale ad. Seven shots are indispensable: front, left side, right side, rear, engine bay, interior (looking down from above and behind the front seats, dashboard in clear view), and an odometer close-up. This isn't art school, so skip creative angles and Instagram effects for plain, well-lit shots. And don't hide body defects. Buyers feel duped when the real-life car has dents they couldn't see online, and while some might respond with a lowball offer, most will walk.

The Test Drive

All these steps are a prelude to the main event: the face-to-face meeting.

Pick a public, easy-to-find place to meet, like a mall or gas station. This is more comfortable for the buyer than a strange neighborhood, and you'll keep your address private. (Of course, if you collect classics in a spotless garage, inviting a buyer to your house could work in your favor. I once went to test-drive an Alfa Romeo owned by a connoisseur with a barn full of vintage racers. Forget the car; I wanted to marry into the family.)

As the seller, you're in control of the test drive. Let the buyer ride shotgun first, to look and listen for details he or she might miss behind the wheel. Your driving sets the tone for the test, so don't do a screaming drag race launch out of the lot unless you're comfortable letting the buyer do the same. After a mile or two at the wheel, switch seats, and suggest that you head back to your meeting spot. Hopefully one of you paid attention to the route.

As for asking price, that's on you, pal. Get a feel for the market by searching completed eBay auctions of same-year examples with similar mileage, and be honest with yourself about your car's condition. Most buyers come in having done some research, so arm yourself with a rock-bottom number and the qualities that justify it before you talk money. When you're confident that your asking price is fair, it's easy to walk away from chiselers. And if you've followed our advice, you're likely to have plenty of interested parties to choose from.

Mathematicians help to unlock brain function

Monday, May 6, 2013

Mathematicians from Queen Mary, University of London will bring researchers one-step closer to understanding how the structure of the brain relates to its function in two recently published studies.

Publishing in Physical Review Letters the researchers from the Complex Networks group at Queen Mary's School of Mathematics describe how different areas in the brain can have an association despite a lack of direct interaction.

The team, in collaboration with researchers in Barcelona, Pamplona and Paris, combined two different human brain networks - one that maps all the physical connections among brain areas known as the backbone network, and another that reports the activity of different regions as blood flow changes, known as the functional network. They showed that the presence of symmetrical neurons within the backbone network might be responsible for the synchronised activity of physically distant brain regions.

Lead author Vincenzo Nicosia, said "We don't fully understand how the human brain works. So far the focus has been more on the analysis of the function of single, localised regions. However, there isn't a complete model that brings the whole functionality of the brain together. Hopefully, our research will help neuroscientists to develop a more accurate map of the brain and investigate its functioning beyond single areas."

The research adds to the recent findings published in Proceedings of the National Academy of Sciences in which the QM researchers along with the Department of Psychiatry at University of Cambridge analysed the development of the brain of a small worm called Caenorhabditis elegans. In this paper, the team examined the number of links formed in the brain during the worm's lifespan, and observed an unexpected abrupt change in the pattern of growth, corresponding with the time of egg hatching.

"The research is important as it's the first time that a sharp transition in the growth of a neural network has ever been observed," added Dr Nicosia.

"Although we don't know which biological factors are responsible for the change in the growth pattern, we were able to reproduce the pattern using a simple economical model of synaptic formation. This result can pave the way to a deeper understanding of how neural networks grow in more complex organisms."

The Complex Networks group at Queen Mary is headed by Professor Vito Latora. Aside from theoretical research about the structure and function of complex networks, the group is working on the characterisation of multi-layer brain networks, aimed at reconciling and integrating different brain signals to produce a more informative picture of the human brain.
