Ant study could help future robot teams work underground

May 20, 2013 ? Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much-despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar to people living in the southern United States.

By studying fire ants in the laboratory using video tracking equipment and X-ray computed tomography, researchers have uncovered fundamental principles of locomotion that robot teams could one day use to travel quickly and easily through underground tunnels. Among the principles is building tunnel environments that assist in moving around by limiting slips and falls, and by reducing the need for complex neural processing.

Among the study's surprises was the first observation that ants in confined spaces use their antennae for locomotion as well as for sensing the environment.

"Our hypothesis is that the ants are creating their environment in just the right way to allow them to move up and down rapidly with a minimal amount of neural control," said Dan Goldman, an associate professor in the School of Physics at the Georgia Institute of Technology, and one of the paper's co-authors. "The environment allows the ants to make missteps and not suffer for them. These ants can teach us some remarkably effective tricks for maneuvering in subterranean environments."

The research was scheduled to be reported May 20 in the early online edition of the journal Proceedings of the National Academy of Sciences. The work was sponsored by the National Science Foundation's Physics of Living Systems program.

In a series of studies carried out by graduate research assistant Nick Gravish, groups of fire ants (Solenopsis invicta) were placed into tubes of soil and allowed to dig tunnels for 20 hours. To simulate a range of environmental conditions, Gravish and postdoctoral fellow Daria Monaenkova varied the size of the soil particles from 50 microns on up to 600 microns, and also altered the moisture content from 1 to 20 percent.

While the particle size and moisture content did produce changes in the volume of tunnels produced and the depth that the ants dug, the diameters of the tunnels remained constant -- and comparable to the length of the creatures' own bodies: about 3.5 millimeters.

"Independent of whether the soil particles were as large as the animals' heads or whether they were fine powder, or whether the soil was damp or contained very little moisture, the tunnel size was always the same within a tight range," said Goldman. "The size of the tunnels appears to be a design principle used by the ants, something that they were controlling for."

Gravish believes such a scaling effect allows the ants to make best use of their antennae, limbs and body to rapidly ascend and descend in the tunnels by interacting with the walls and limiting the range of possible missteps.

"In these subterranean environments where their leg motions are certainly hindered, we see that the speeds at which these ants can run are the same," he said. "The tunnel size seems to have little, if any, effect on locomotion as defined by speed."

The researchers used X-ray computed tomography to study tunnels the ants built in the test chambers, gathering 168 observations. They also used video tracking equipment to collect data on ants moving through tunnels made between two clear plates -- much like "ant farms" sold for children -- and through a maze of glass tubes of differing diameters.

The maze was mounted on an air piston which could periodically be fired, dropping the maze with a force of as much as 27 times that of gravity. The sudden movement caused about half of the ants in the tubes to lose their footing and begin to fall. That led to one of the study's most surprising findings: the creatures used their antennae to help grab onto the tube walls as they fell.

"A lot of us who have studied social insects for a long time have never seen antennae used in that way," said Michael Goodisman, a professor in the Georgia Tech School of Biology and one of the paper's other co-authors. "It's incredible that they catch themselves with their antennae. This is an adaptive behavior that we never would have expected."

By analyzing ants falling in the glass tubes, the researchers determined that the tube diameter played a key role in whether the animals could arrest their fall.

In future studies, the researchers plan to explore how the ants excavate their tunnel networks, which involves moving massive amounts of soil. That soil is the source of the large mounds for which fire ants are known.

While the research focused on understanding the principles behind how ants move in confined spaces, the results could have implications for future teams of small robots.

"The problems that the ants face are the same kinds of problems that a digging robot working in a confined space would potentially face -- the need for rapid movement, stability and safety -- all with limited sensing and brain power," said Goodisman. "If we want to build machines that dig, we can build in controls like these ants have."

Why use fire ants for studying underground locomotion?

"These animals dig virtually non-stop, and they are good, repeatable study subjects," Goodisman explained. "And they are very convenient for us to study. We can go outside the laboratory door and collect them virtually anywhere."

The research described here has been sponsored by the National Science Foundation (NSF) under grant POLS 095765, and by the Burroughs Wellcome Fund. The findings and conclusions are those of the authors and do not necessarily represent the official views of the NSF.

Art, Music & Dance Can Help Ease Anxiety, Depression in Cancer ...

Art, Music & Dance Help Ease Anxiety, Depression in Cancer Patients For patients with cancer, participating in art, music and dance therapy may help relieve depression and anxiety, according to new research.

?People with cancer very often feel like their body has been taken over by the cancer. They feel overwhelmed,? said Dr. Joke Bradt, a music therapist from Drexel University in Philadelphia.

?To be able to engage in a creative process? that stands in a very stark contrast to sort of passively submitting oneself to cancer treatments,? said Bradt.

Researchers analyzed 27 past studies of nearly 1,600 people who were randomly assigned to receive some form of creative arts therapy or not, during or after cancer treatment. Most of the patients had breast cancer or a type of blood cancer?such as leukemia and lymphoma.

Music, art and dance therapy programs varied in how often the sessions were held and over what time span. Over half of the programs did not involve counseling with trained therapists.

Overall, patients with cancer who were assigned to creative arts treatments reported less depression, anxiety and pain and a better quality of life during the programs than those who were put on a wait list or continued receiving typical care.

For example, in one 2010 study, listening to half an hour of familiar music dropped pain levels in half for 42 percent of hospitalized patients, while just eight percent of those in a comparison group experienced relief.

Those in creative arts therapy did not report being any less tired than patients assigned to a control group. And most of the other benefits discontinued once therapy ended, the researchers reported in the journal JAMA Internal Medicine.

Researchers noted that the benefits tied to creative arts therapies were small, but similar to those of other complementary techniques such as yoga and acupuncture.

Lead author Timothy Puetz, Ph.D.,?from the National Institutes of Health in Bethesda, Md., said researchers have believed music and art therapy may help cancer patients ?for a long time,? although rigorous studies have been lacking.

?People have really broadened their perspectives on what is health and have moved beyond just the physical,? said Puetz.

?More and more clinicians and certified creative arts therapists? they?re actually reaching out to each other now, and discussions are on the table to try to bring this type of therapy to cancer patients.?

Bradt said that, for some patients, working directly with an arts therapist may be most helpful, but it isn?t essential. For example, anyone looking to refocus away from the anxiety of a cancer diagnosis and treatment can join a choir or an art class.

?We all know that music or art or just aesthetic beauty in general makes us feel better,? she said. ?I do not want to underestimate the power of just the arts by themselves.?

Gaining Natural Health with Dieting and Smart Decisions ? Hot ...

It?s a pretty good bet that everybody wants to be healthy and to look good. For some reason, however, this is where things part ways because not everybody is able to reach natural health through dieting. We are not here to try and figure out the reasons for that.

All any person can do is try to educate people about what is available and what can be done. Your job, then, is to find the absolute best information possible and put it to good use. So, as you can see, everybody has a responsibility, and actually we all choose our path.

You have to ask yourself what makes for regular eating in your diet. You can make plenty of progress on your own just by cutting out the food and beverages that isn?t healthy. If you drink a lot of soft drinks and eat fast foods a lot, then you know what to do about that. If that is regular eating for you, then you must change that. But if you want it to work, it?s important to approach it gradually?you can still have things like that every once in a while, after all. It?s important that, if nothing else, you just don?t eat them every single day?it can be a big accomplishment by yourself. If your budget is tight, you need to learn what you can do that doesn?t cost all that much but is still healthy.

Should you eat saturated fats or not, has been talked to death. But the truth of the matter is your body needs a certain amount of saturated fat. This is not a green light to overdo them, at the same time. You need to embrace the principle of common sense, along with eating right and natural health will be the result. In the opinion of some, a number of organizations and people are too extreme with their thinking on saturated fats, and it is unhealthy to severely limit them. A lot will depend on your physical condition at the present time, along with how healthy you are.

Figuring out how to find true and natural health through dieting is definitely something that you can do and it doesn?t even need to take very much time to do it. The element of time is important here because you probably understand more than you think you do. And what you don?t already know, like which foods are natural fat burners during the digestive process, you can learn.

Being thorough as we are wont to do here at WTLC, let's take a look at some alternate covers.

This week's issue of Sports Illustrated highlights the pitching of New York Met Matt Harvey in what I'm sure is a lovely article by Tom Verducci. I'm a Cubs fan myself, so I hate baseball with the blazing passion of one million dying suns. If I think about it for more than a few minutes I start to think about the 2003 NLCS and then I speak in nothing but 1990's Ice Cube lyrics for the rest of the day. But good for Matt Harvey, I'm sure his family is proud of him. Be that as it may, it's not even June yet and we're seeing baseball on the cover. Not acceptable. Being thorough as we are wont to do here at WTLC, let's take a look at some alternate covers.

Afghans tell of US soldier's killing rampage

(AP Photo/Anja Niedringhaus)

(AP) ? Sitting on a dirty straw mat on the parched ground of southern Afghanistan, Masooma sank deeper inside a giant black shawl. Hidden from view, her words burst forth as she told her side of what happened to her family sometime before dawn on March 11, 2012.

According to Masooma, an American soldier wearing a helmet equipped with a flashlight burst into her two-room mud home while everyone slept. He killed her husband, Dawood, punched her 7-year-old son and shoved a pistol into the mouth of his baby brother.

"We were asleep. He came in and he was shouting, saying something about Taliban, Taliban, and then he pulled my husband up. I screamed and screamed and said, 'We are not Taliban, we are not government. We are no one. Please don't hurt us,'" she said.

The soldier wasn't listening. He pointed his pistol at Masooma to quiet her and pushed her husband into the living room.

"My husband just looked back at me and said, 'I will be back.'" Seconds later she heard gunshots, she recalled, her voice cracking as she was momentarily unable to speak. Her husband was dead.

Masooma, who like many Afghans uses only one name, defied tribal traditions that prohibit women from speaking to strangers to talk to The Associated Press while ? half a world away ? the military prepares to court-martial a U.S. serviceman in the killing of her husband and 15 other Afghan civilians, mainly women and children.

The AP also interviewed other villagers about the case, all of whom are identified by the U.S. Army as witnesses or relatives of witnesses. They included a sister and brother who were wounded and two men who were away during the killings and returned to find wives and children slain. The sister and brother told AP how they tried to run away and hide from a soldier with a gun, only to be shot ? and see their neighbors and grandmother killed.

U.S. Army Staff Sgt. Robert Bales of Lake Tapps, Washington, is accused of the killings. Prosecutors say Bales slipped away from his remote outpost to attack two nearby villages, returning in the middle of the rampage and then for a final time soaked in blood. During a hearing last fall, other soldiers testified that Bales spent the evening before the massacre watching a movie about revenge killings, sharing contraband whiskey from a plastic bottle and discussing an attack that cost one of their comrades his leg.

Bales has not entered a plea, but his lawyers have not disputed his involvement in the killings. They have said his mental health may be part of his defense; he was on his fourth combat deployment and had suffered from post-traumatic stress disorder as well as a concussive head injury while serving in Iraq. The Army is seeking the death penalty.

The killings took place in Kandahar's Panjwai district, deep in the ethnic Pashtun heartland that spawned the Taliban movement, an area where women are hidden inside all-enveloping burqas and rarely leave their homes.

Masooma's account of the night has been reported variously over the past year, differing over details such as whether there was one or more than one U.S. soldier involved. However, the four hours she recently spent with the AP was her first face-to-face interview with a news organization. She spoke as her burly brother-in-law Baraan loomed nearby.

The interview took place outside Baraan's single-story mud home in Kandahar city, because Alokzai and Najiban villages, where the killings occurred, are too hostile for foreigners to visit. Even in Kandahar, some 150 kilometers (90 miles) away, the AP journalists sought to avoid being seen by Baraan's neighbors, who he feared would react negatively to their presence.

Masooma said that the soldier returned to the family's bedroom after killing her husband. She stood in terror. Her children hid under their blankets. The soldier moved slowly and seemed angry. Gesturing to show how he hit her in the arms and shoved her to the ground, Masooma said he then moved toward her son Hikmatullah, then 7.

Her son said he remembers the sight of the attacker in full military uniform. "I was so afraid. I pretended I was asleep," he said.

Masooma said the soldier found Hikmatullah and punched him repeatedly in the head.

She said the soldier then found her 2-year-old daughter, Shahara. He grabbed her pigtails and violently shook her head back and forth.

He then went to the crying baby Hazratullah and shoved the muzzle of his black pistol into the infant's mouth, she said.

"He just held it there in his mouth. I screamed and screamed, 'He is just a baby. Don't kill him. Don't kill him.' But he just kept the gun in his mouth. He didn't say anything. He just stared at him," she recalled. As she recounted the attack, Hazratullah fussed and squirmed beneath the giant shawl that enveloped her.

After some time, she said, the soldier took the gun from the baby's mouth and walked back into the living room. Masooma dug her bare foot into the dirt to demonstrate how the soldier slipped his foot beneath her husband's head to lift it from the floor, as if to be sure he was really dead. The soldier looked down at her husband, shrugged his shoulders and returned to searching her home. After he finished rifling through their belongings, he left.

Investigators say Bales was armed with a 9 mm pistol and an M-4 rifle outfitted with a grenade launcher when he walked off his base and went on a nighttime killing spree in five homes, including Masooma's. He faces 16 counts of premeditated murder; six counts of attempted murder; seven counts of assault; and one count each of possessing steroids, using steroids, destroying a laptop, burning bodies, and using alcohol. He is being held in a military prison at Joint Base Lewis-McChord, south of Seattle in Washington state.

On April 23, Bales appeared in a military courtroom at Joint Base Lewis-McChord for a hearing that focused on what might happen if he is convicted, including which relatives and friends could speak on his behalf during a sentencing hearing. Such testimony could help determine whether he receives the death penalty.

The U.S. government flew Baraan and five other Afghan men ? all members of families who were attacked ? to Seattle to familiarize them with the U.S. judicial system and notify them that they would likely have to return when the court-martial begins in September. Only three of those who went to the U.S. in March said they saw the attack. Some, like Baraan, went on behalf of relatives who were slain or women prevented from traveling.

None of the Afghan witnesses was able to identify Bales as the attacker, but other evidence, including tests of the blood on his clothes, implicated him, according to testimony from a DNA expert.

The AP also spoke with several others who survived the attack or lost family members. To avoid putting the Afghans in danger should they be seen talking to foreigners, the AP arranged for those interviews to take place at a nondescript hotel in Kandahar. The Afghans drove the dusty, dangerous road from their villages to the hotel and then returned home.

Said Jan, an elderly man who was visiting Kandahar during the attack and lost his wife and three other family members, said he went to the United States expecting justice.

"I thought we were going to America to see him hanged," Said Jan said. "Instead they showed us a courtroom and kept us in rooms asking us more and more questions."

Said Jan said he wasn't interested in returning for the trial.

"None of us will go," agreed Mohammed Wazir, who also went to the U.S. in March. "Why would we care about seeing America? We will only go if he is hanged."

Wazir said he returned home from a trip the morning after the attack to find 11 members of his family dead ? his wife, his mother, two brothers, a 13-year-old nephew and his six children. Their bodies were partially burned.

He was left only with his 3-year-old son, Habib Shah, who had accompanied him on the trip to Spin Boldak, a town on the Pakistani border.

While Wazir spoke of the horror of finding his home spattered with blood, still smelling of burned flesh, Habib, now 4, played by his side, chewing on his toy police car, occasionally running it across his father's legs, loading small candies on the roof and giggling when they tumbled off.

"He misses his mother all the time," Wazir said, trying to straighten Habib's curly brown hair.

From another home that was attacked that night, 16-year-old Rafiullah remembers the American soldier smashing through the door waving his pistol. Awakened in a small room with his grandmother and his sister Zardana, he said he didn't know what to do. "We just ran and he ran after us."

Zardana, 11, said a cousin dashed over to help. He was shot and killed, she said. "We couldn't stop. We just wanted somewhere to hide. I was holding on to my grandmother and we ran to our neighbors." Their neighbor, Naim, came out of his house to see what the noise was all about and was shot and wounded. His daughter then ran to him but was killed by the American soldier, Zardana said, struggling to remember and fiddling with her green scarf decorated with tiny sequins.

Zardana, who said she saw soldiers in a nearby field as she ran from one house to the next, remembers trying to hide behind her grandmother at the neighbor's house. But the soldier found them.

Gesturing with his hand as if spraying the room with gunfire, Rafiullah said the soldier "just went bang, bang, bang."

Rafiullah was wounded in both his legs, his grandmother was killed and Zardana was shot in the head.

She removed her scarf to show where the wound had healed; the effects will last a lifetime. She suffered nerve damage on her left side and has to walk with a cane. Her hand is too weak to hold anything heavy.

Zardana spent about two months recovering at the Kandahar Air Base hospital and three more at a naval hospital in San Diego receiving rehabilitation therapy, accompanied by her father, Samiullah.

Listening as she spoke, Samiullah smiled at his lanky daughter, encouraging her to say the only English phrase she knows: "Thank you."

Zardana spoke of her treatment in San Diego and the doctors and nurses who helped her learn to walk again, gave her toys and still find ways to stay in touch.

"They showed me so much love," she said with a tiny smile. "They asked me about what happened and when I told them how my grandmother died and how afraid I was and how I was shot, they cried and cried."

The accounts of many villagers have varied over the past year, making it a challenge for investigators and journalists to find out a full narrative of the attack.

For example, Masooma gave an telephone interview to a reporter days after the attack, with Baraan, her brother-in-law, acting as a translator. According to the resulting story, she described a single attacker in her home, but said she saw many soldiers outside.

Three months later, her family allowed a female Army investigator to question her. The investigator testified at a hearing last fall that Masooma clearly stated two soldiers carried out the attack. The investigator said she had no reason to doubt Masooma's credibility.

At the same hearing, Baraan testified, insisting Masooma was mistaken when she said there were two soldiers. Lawyers for the soldier accused in the killings suggested Baraan might be influencing Masooma ? especially since the defense was not allowed to speak with her.

No physical evidence has emerged to suggest more than one soldier took part in the killings. Surveillance footage from the base showed one soldier returning to the camp; the soldiers who greeted him said he was covered in blood.

Nevertheless, many Afghans villagers, including some eyewitnesses, continue to insist multiple soldiers were present during the attack.

In the interview with the AP, Masooma did not waver in her insistence that one soldier attacked her home, and Baraan denied that she ever reported seeing many soldiers outside. Masooma did recall flares lighting the sky until "night seemed like day" ? which is consistent with testimony from the hearing, as guards said they fired a flare that illuminated the sky for 20 seconds after hearing gunshots. Masooma also said she heard helicopters overhead; there was no corroborating testimony at the hearing.

Masooma is absolutely certain of one thing: what it will take for her to find closure.

"I just want to see him killed," she said of Bales. "I want to see him dead. Then I can let go."

Larry Page Reminded Us Why We Love Google Today

Larry Page, Google's CEO and co-founder, closed out the Google I/O keynote today with a sentimental, almost subdued speech. He didn't sound like a CEO. He sounded like a guy in charge of a company he genuinely thought could change the world. And it was a wonderful reminder that Google used to be, can be, and in many ways still is, so much more than a company.

Page began with a story about his father, and how the family used to drive across the country to see a robotics conference, and how lucky he was to be exposed to that at a young age. He argued that just the simple exposure to the broader world of technology was enough to open a cosmos of possibilities up to him. And you got the sense that he just wanted to use Google to drive the rest of us to whatever robotics conference is next.

About halfway into the speech, he came to a phrase that's as good a summation of Google over the past 18 months or so as anything. "We should be building great things that don't exist." Not focusing on the platform wars or sniping with other companies or aiming at small scale iterations. You aim for something like Glass, maybe, or something even more ambitious. You make what no one thinks is even possible yet. Consciously or not, Google's mirrored that philosophy recently, keeping its house in order with APIs and geek service, but expanding the scope of its aspirations, with Glass, the driverless cars initiative, or even crazy-affordable Chromebooks and high-speed internet.

Page argued that it's the small scale that we've been operating on that is what's really dissuading more projects like that. "If you're going to make a smartphone for a dollar, like one dollar, that's almost impossible," he responded to one question. "But if you took a longer view, like 50 years, you'd change how you look at your investments, and find a way to make money. You just need a deep understanding of what you're doing."

In his speech and the Q&A that followed, Page focused on things that didn't have anything, directly at least, to do with Android or Chrome or developing, at times just brushing past questions that seemed too small for his agenda for the day. Asked about a Glass production run, he stumbled through some pseudo-PR speak before saying he was just exited about how he'd use Glass with his kids. There was lip service to how much he appreciated the developers in attendance, but he focused more on the ways the things that Google is doing can help real people in real ways.

Yes, that's a sales pitch, and naive in a myriad of ways if you want to be a cynic, but that's not how it came off. He was optimistic about search or Google Now making people's lives easier, or less time behind the wheel of a car and more time with your family, but sounded more wistful about them as a means to get AWAY from your computers. Like a guy who got that we love our phones, but that shouldn't be the whole picture, and that computers are supposed to be there to help us.

"We're not organized enough to solve that problem," he said. "And our computers aren't helping us do that. We have to make computer software on the internet that helps solve those problems, that solves, as a side effect, that helps people become educated about what they're looking for. We're trying to serve both modes, and trying to get computers to help you do that."

And sometimes, how that happens might seem a little crazy. Larry had a bunch of totally rational ideas, that in that rationality totally radical, about progress in legislation and the medical fields surrounding tech. "Like, the law can't be right if it's 50 years old," he said about the regulations in place, limiting what weird stuff Google might want to try. "It's before the internet. I think we need to, or the million watching, need to go into other areas and help those areas and help them understand technology. And we have't really. The other thing is we haven't built mechanisms for experimentations, because they aren't allowed by regulations because we don't want the world to change too fast."

A place, a mechanism, where people can just experiment. Do whatever the hell they want, free of laws and regulations and the glacial bureaucracy governing technologies it doesn't and likely never will understand. Crazy talk, basically, the kind of stuff you start throwing out a half hour before closing time in a bar argument. Except the guy saying it is Larry Page, and you feel almost compelled to believe him. Google's gone after medical advancements and lost?regulatory problems are too much unless someone locks down "technological leverage" to force an issue, as with DNA sequencing, Page says?but it's experienced enough that you wonder if Page's crazy ideas don't come from a place of deep understanding.

It's a magnetic way to think about the world. Page talked about his decision to disclose his vocal cords condition yesterday, and how a lot of people might not have because they were worried about their insurance?and that's dumb. "We should change the rules around insurance," he said, almost impossibly matter-of-factly, as if that's how the world works. "The whole point of insurance is to insure people." It was heartfelt enough that you believed he meant it, and he's Larry Page, so you had to stop and wonder, What if he's right, and then, What if he can do it?

If he can, the best chance is probably just brute cash flow. There are a lot of zeroes in Google, after all, and Washington might be lost in a talk about anything more advanced than a graphing calculator, but it has always understood zeroes. Google's been painted as a tech baron recently, pouring cash into lobbying Washington for this or that, but here, for a split second, you had to wonder if it's possible its heart's still in the right place.

Rooting for lobbyists. That's what Larry Page did today. He just talked about how he wishes Google could change the world, and oozed enough sincerity that we couldn't help but believe him, and in turn, in Google.

How one group got past IRS scrutiny

MediaTrackers.org

In May 2011, Drew Ryun, a conservative activist and former Republican National Committee staffer, began filling out the Internal Revenue Service application to achieve non-profit status for a new conservative watchdog group.

He submitted the paperwork to the IRS in July 2011 for a news site called Media Trackers, which calls itself a "non-partisan investigative watchdog dedicated to promoting accountability in the media and government." Although the site has investigated Republicans like Ohio Gov. John Kasich and Florida Gov. Rick Scott, the site's organizers are unapologetically conservative.

"One thing we don't hide is: 'Yeah, we're conservative?free-market, free-enterprise, full-spectrum conservative,'" Ryun told Mother Jones magazine last year.

Eight months passed without word from the agency about the group's application, Ryun said. In February 2012, Ryun's attorney contacted the IRS to ask if it needed more information to secure its non-profit status as a 501(c)3 organization. According to Ryun, the IRS told him that the application was being processed by the agency's office in Cincinnati, Ohio?the same one currently facing scrutiny for targeting conservative groups?and to check back in two months.

As directed, Ryun followed up with the IRS in April 2012, and was told that Media Trackers' application was still under review.

When September 2012 arrived with still no word from the IRS, Ryun determined that Media Trackers would likely never obtain standalone non-profit status, and he tried a new approach: Starting over. He applied for permanent non-profit status for a separate group called Greenhouse Solutions, a pre-existing organization that was reaching the end of its determination period.

The IRS approved Greenhouse Solutions' request for non-profit status in three weeks.

When news broke last week that the IRS had applied heavier scrutiny to conservative groups seeking non-profit status from 2010-2012, Ryun said he became convinced that his second application was approved quickly because he applied under the Greenhouse Solutions title, which he called a "liberal-sounding name."

"Within three weeks, Greenhouse received permanent non-profit status from the IRS, and the IRS approval was transmitted to us from its Cincinnati office. We then rolled the Media Trackers project into Greenhouse and began work on a number of new projects," Ryun told Yahoo News in an interview. "Do I think we benefited from what many think is a liberal-sounding name? Absolutely."

In December 2012, Ryun simply made Media Trackers a project of Greenhouse Solutions and withdrew the Media Trackers application.

The IRS website explains why some requests for tax-exempt status take longer than others to process.

"Sometimes, representatives of exempt organizations and practitioners question why certain applications for tax exemption are processed faster than others. Not all applications are the same," the site reads. "While many are complete when received and involve straight-forward scenarios, others may be incomplete or involve complex issues that require further development."

The IRS is currently under fire from both Democrats and Republicans, and Attorney General Eric Holder on Tuesday announced that he had directed the FBI to launch a criminal probe into the IRS. The same day, the Treasury inspector general for tax administration submitted a review of the IRS' practices, which found that the agency had used "inappropriate criteria" to determine which groups were eligible for non-profit status. Current and former IRS officials are expected to testify about the issue before House committees starting Friday.

Balotelli to walk off next time he is racially abused

AC Milan's Mario Balotelli looks on during their Italian Serie A soccer match against AS Roma at the San Siro stadium in Milan

updated 1:48 p.m. ET May 15, 2013

(Reuters) - Mario Balotelli will walk off the pitch the next time he suffers racial abuse from the crowd, the AC Milan and Italy forward said on Wednesday.

Balotelli told CNN in an interview that he had come close to abandoning the match after being insulted by visiting Roma fans at San Siro on Sunday.

"If it happens one more time, I'm going to leave the pitch, because it's so stupid," he said.

"I was about to leave the pitch on Sunday but they are going to think that I wanted to leave because maybe we had some difficulty with the game...."

Milan were down to 10 men at the time and the game ended 0-0.

"I said it's better we play and then we talk, but if it wasn't for this reason I was going to leave the pitch," Balotelli added.

Sunday's match was halted for two minutes by the referee while announcements were made warning the fans to stop their abuse. Roma were fined 50,000 euros for the incident on Monday.

Balotelli said the incident had changed his way of thinking. "I always said if it happens in the stadium, I would just do (behave) as if nobody had done anything and that I don't care, but now I think I've changed my mind a bit."

Twitch gaming video platform comes to Xbox 360, watch and play from the same place

How does a dedicated gamer relax when they're finally beat on Call of Duty? Surely by watching others suffer the same fate, right? Well, now that just got even easier with an official Twitch app for Xbox 360. The game-centric video service finds a natural home on the console, which could go some way to augment the platform's already 34-million strong audience (or at least prevent hundreds of wasted gaming calories used when switching screens). It's not clear if there will be the option to bring your premium credentials along with you. But, we do know the app will bring access to the top 300 live Twitch channels, albeit initially only for Xbox Live Gold subscribers. Still, as a dedicated gamer, you probably already are one, right?

Micromachining: Inclinations sounded out

May 13, 2013 ? A novel type of tilt sensor may extend the capabilities of ultrasonic devices already used in a range of applications.

Echolocation is a powerful technique that uses sound or ultrasound waves to locate objects and surfaces. Ships and submarines, for example, use it to avoid collisions, and dolphins and microbats use it to locate prey (see image). Hongbin Yu and co-workers from the A*STAR Institute of Microelectronics, Singapore, have now used echolocation to measure the inclination of millimeter-sized ultrasonic sensors. In this new setting, their technique should extend the capabilities of devices that already use ultrasonic components, whether for locating defects in materials, visualizing anatomical structures or determining range.

Yu and his co-workers built on the success that so-called 'capacitive micromachined ultrasonic transducers' (CMUTs) have achieved over the past decade in generating and detecting ultrasound signals. These devices are fabricated using silicon micromachining technology, so the components are very compact and can be conveniently integrated with standard electronics components, which are also based on silicon.

"Our main goal was to explore a new application of the CMUT device," says Yu. Consequently, the researchers harnessed these ultrasonic components for measuring tilt angles. They used three micromachined CMUTs -- two senders and a common receiver -- each measuring less than a tenth of a millimeter across. To test this array, they immersed it in a bath filled with oil. As they tilted the device, the oil surface stayed level -- in the same manner that the water surface in a tilted glass would remain horizontal. However, the distances between the surface and the sensors at the bottom changed such that one sensor became closer to the surface than the other.

By measuring how long it took the ultrasound waves to travel from each of the senders to the receiver, via the oil surface where the waves were reflected, Yu and his co-workers could accurately determine the distances between the sensors and the surface. They could then calculate the tilt angle that the CMUT array had relative to the oil surface.

As many devices already contain ultrasonic components, the new sensor should be useful in a number of applications, according to Yu. "As one example, in an automotive robotic arm equipped with ultrasound transducers for fault detection, a tilt-sensing function should help improve the arm-control accuracy without greatly increasing the complexity of the device," he explains.

Other areas where tilt-angle measurements are important include level determination for instrumentation and motion-state monitoring. With the team's innovation, such functionality may now be added to ultrasonic medical-imaging and non-destructive materials-testing devices.

Nineteen shot in New Orleans Mother's Day parade

(Reuters) - Nineteen people including two children were shot in New Orleans on Sunday when gunfire erupted at a Mother's Day parade, and city police said they were searching for three suspects.

Ten men, seven woman, a girl and a boy both age 10 were hit when wild gunfire opened up at about 1:45 p.m. as the parade marched along North Villere Street, according to police spokesman Garry Flot.

Two victims are undergoing surgery, Flot said in a statement. The children were grazed and are in good condition, he said. It was unclear if the victims were marching or bystanders watching the parade.

Police superintendent Ronal Serpas told reporters that officers saw three suspects running away, with one about age 18 to 22. No arrests were made.

"It appears that these two or three people, for reasons unknown to us, started shooting at, towards or in the crowd," Serpas said, adding that the incident was over in "just a couple of seconds."

Serpas said a witness reported hearing two different types of gunshot, which he said indicated two weapons were involved.

Mayor Mitch Landrieu called the shooting part of "the relentless drum beat of violence" on the streets of New Orleans.

"It's a culture of violence that has enveloped the city for a long, long period of time," Landrieu told a news conference outside University Hospital, where three victims were being treated for serious injuries.

Photographs of the aftermath in the Times-Picayune newspaper showed a man lying on his stomach beside a pool of blood, being helped by two bystanders. Other photos showed a man in shorts sitting on a cobbled street, his calf bleeding and covered with a bandana.

Emergency medical responders took 11 people to Interim LSU Public Hospital in New Orleans, according to hospital spokesman Marvin McGraw

Violent crime in New Orleans ranks above the national average in FBI surveys. A poll of city residents in 2010 found crime to be their greatest concern.

In February, four people were wounded in a shooting outside a nightclub in the city's French Quarter as crowds gathered for Mardi Gras celebrations.

Though many mysteries of the brain remain unsolved, advances in medicine and technology are bringing us closer to understanding exactly how it functions. Here are stories on brain breakthroughs, the scientists who made them, the patients who experienced them, and the ethics behind it all:

The Brain That Changed Everything
Luke Dittrich ? Esquire ? October 2010

When a neurosurgeon cut in to Henry Molaison?s brain in 1953, his life changed forever. So would everything that science ever knew about memory.

?Brain surgery is an ancient craft ? there is a four-thousand-year-old hieroglyphic text describing successful operations ? and among my grandfather's most interesting artifacts was a collection of premodern and tribal neurosurgical instruments. As a kid, I found those picks and blades fascinating and terrible to contemplate. It wasn't just the age of the tools, it was the acts they were intended for. Brain surgery, whatever the era, always requires at least two frightening qualities in its practitioners: the will to make forcible entry into another man's skull, and the hubris to believe you can fix the problems inside.?

Could Conjoined Twins Share a Mind?
Susan Dominus ? New York Times Magazine ? May 2011

On the shared life of Tatiana and Krista Hogan.

?Twins joined at the head?the medical term is craniopagus?are one in 2.5 million, of which only a fraction survive. The way the girls? brains formed beneath the surface of their fused skulls, however, makes them beyond rare: their neural anatomy is unique, at least in the annals of recorded scientific literature. Their brain images reveal what looks like an attenuated line stretching between the two organs, a piece of anatomy their neurosurgeon, Douglas Cochrane of British Columbia Children?s Hospital, has called a thalamic bridge, because he believes it links the thalamus of one girl to the thalamus of her sister. The thalamus is a kind of switchboard, a two-lobed organ that filters most sensory input and has long been thought to be essential in the neural loops that create consciousness. Because the thalamus functions as a relay station, the girls? doctors believe it is entirely possible that the sensory input that one girl receives could somehow cross that bridge into the brain of the other. One girl drinks, another girl feels it?

The Itch
Atul Gawande ? The New Yorker ? June 2008

What the sensation of an uncontrollable itch can tell us about how the brain operates.

?Contemplating what it?s like to hold your finger in a flame won?t make your finger hurt. But simply writing about a tick crawling up the nape of one?s neck is enough to start my neck itching. Then my scalp. And then this one little spot along my flank where I?m beginning to wonder whether I should check to see if there might be something there. In one study, a German professor of psychosomatics gave a lecture that included, in the first half, a series of what might be called itchy slides, showing fleas, lice, people scratching, and the like, and, in the second half, more benign slides, with pictures of soft down, baby skin, bathers. Video cameras recorded the audience. Sure enough, the frequency of scratching among people in the audience increased markedly during the first half and decreased during the second. Thoughts made them itch.?

The Strange Neuroscience of Immortality
Evan R. Goldstein ? The Chronicle of Higher Education ? July 2012

How some scientists are turning to connectomes?maps of the brain?s neural circuitry?to make the case for brain preservation, mind uploading, and eternal life.

?Among some connectomics scholars, there is a grand theory: We are our connectomes. Our unique selves?the way we think, act. Feel?is etched into the wiring of our brains. Unlike genomes, which can never change, connectomes are forever being molded and remolded by life experience. Sebastian Seung, a professor of computational neuroscience at the Massachusetts Institute of Technology and a prominent proponent of the grand theory, describes the connectome as the place where ?nature meets nurture.?

?Hayworth takes this theory a few steps further. He looks at the growth of connectomics?especially advances in brain preservation, tissue imaging, and computer simulations of neural networks?and sees something else: a cure for death.

The Brain on Trial
David Eagleman ? Atlantic ? July 2011

Should the discovery of a brain disease or disorder excuse a person from prosecution? How recent advancements in brain science are changing understandings of volition.

?As our understanding of the human brain improves, juries are increasingly challenged with these sorts of questions. When a criminal stands in front of the judge?s bench today, the legal system wants to know whether he is blameworthy. Was it his fault, or his biology?s fault?

?I submit that this is the wrong question to be asking. The choices we make are inseparably yoked to our neural circuitry, and therefore we have no meaningful way to tease the two apart. The more we learn, the more the seemingly simple concept of blameworthiness becomes complicated, and the more the foundations of our legal system are strained.?

The Split Brain: A Tale of Two Halves
David Wolman ? Nature ? March 2012

How a radical surgery intended to separate the right hemisphere of the brain from the left impacted both researchers and patients.

?But what Vicki could never have known was that her surgery would turn her into an accidental superstar of neuroscience. She is one of fewer than a dozen 'split-brain' patients, whose brains and behaviours have been subject to countless hours of experiments, hundreds of scientific papers, and references in just about every psychology textbook of the past generation. And now their numbers are dwindling.

?Through studies of this group, neuroscientists now know that the healthy brain can look like two markedly different machines, cabled together and exchanging a torrent of data. But when the primary cable is severed, information ? a word, an object, a picture ? presented to one hemisphere goes unnoticed in the other.?

As Good as Dead
Gary Greenberg ? The New Yorker ? August 2001

Is there really such a thing as brain death?

?When I spoke to Nick?s parents, they still had trouble with the notion that, to become a donor, it was not enough for their son to die with his body more or less intact. He would have to have the right kind of death, with the systems in his body shutting down in a particular order. ?I?m so confused about this part of it,? his mother said. ?I don?t understand why, if his heart stops beating, they can?t put him back on a respirator.? Rick, too, was confused about the moment at which ?the plug will be pulled.? In reality, there is no moment when the plug is pulled; to keep the organs viable, the respirator is left operating?and the heart keeps beating?until the surgeon removes the organs.

?Confusion about the concept of brain death is not unusual, even among the transplant professionals, surgeons, neurologists, and bioethicists who grapple with it regularly. Brain death is confusing because it?s an artificial distinction constructed, more than thirty years ago, on a conceptual foundation that is unsound. Recently, some physicians have begun to suggest that brain-dead patients aren?t really dead at all?that the concept is just the medical profession?s way of dodging ethical questions about a practice that saves more than fifteen thousand lives a year.?

State Dep't sought to change Libya talking points

(AP) ? Senior State Department officials pressed for changes in the talking points that U.N. Ambassador Susan Rice used after the deadly attack on the U.S. diplomatic mission in Libya last September, expressing concerns that Congress might criticize the Obama administration for ignoring warnings of a growing threat in Benghazi.

An interim report by Republicans on five House committees last month had detailed how the talking points were changed, days after the Sept. 11 attack and in the heat of the 2012 presidential campaign. New details about the political concerns and the names of the administration officials who wrote emails concerning the talking points emerged on Friday.

The White House has insisted that it made only stylistic changes to the intelligence agency talking points in which Rice suggested that protests over an anti-Islamic video set off the attack that killed Ambassador Chris Stevens and three other Americans. Before the presidential election, the administration said Rice's talking points were based on the best intelligence assessments available in the immediate aftermath of the attack.

But the report and the new details Friday suggest a greater degree of White House and State Department involvement.

The latest developments are certain to add fuel to the politically charged debate over Benghazi. Republicans have suggested that the Obama administration sought to play down the possibility of terrorism during the campaign and has misled the country. A senior administration official reiterated Friday that the talking points were based on intelligence assessments and developed during an interagency process, which included the CIA, officials from the Director of National Intelligence, State Department, FBI and the Justice Department.

The official commented only on condition of anonymity because the official was not authorized to speak publicly about the investigation

Last Sept. 14, two days before Rice's appearance, the CIA's initial draft of the talking points referred to Islamic extremists taking part in the attack in Benghazi, possible links to Islamic extremist group Ansar al-Sharia, a CIA assessment of threats from extremists linked to al-Qaida and a mention of five previous attacks against foreign interests in Benghazi.

A congressional official who reviewed 100 pages of emails and the 12 pages of talking points said former State Department spokeswoman Victoria Nuland expressed concerns about the talking points, writing that they "could be abused by members of Congress to beat the State Department for not paying attention to agency warnings so why would we want to seed the Hill."

The reference to al-Sharia was deleted, but Nuland wrote later that night, "these don't resolve all my issues and those of my building leadership, they are consulting with NSS," a reference to the National Security staff within the White House.

A meeting of senior officials was convened on Saturday morning after the attack to work on the talking points and they included officials from the White House, State Department and CIA.

Deleted from the final talking points were mention of al-Qaida, the experience of fighters in Libya and Islamic extremists, according to the congressional official, who spoke only on condition of anonymity because the official was not authorized to speak publicly about the emails that have not been released.

Increases in heart disease risk factors may decrease brain function

May 2, 2013 ? Brain function in adults as young as 35 may decline as their heart disease risk factors increase, according to new research in the American Heart Association journal Stroke.

"Young adults may think the consequences of smoking or being overweight are years down the road, but they aren't," said Hanneke Joosten, M.D., lead author and nephrology fellow at the University Medical Center in Groningen, The Netherlands.

"Most people know the negative effects of heart risk factors such as heart attack, stroke and renal impairment, but they do not realize it affects cognitive health. What's bad for the heart is also bad for the brain."

The Dutch study included 3,778 participants 35- to 82-years-old who underwent cognitive function tests that measure the ability to plan and reason and to initiate and switch tasks. A separate test gauged memory function. The Framingham Risk Score determined their risk for cardiovascular events in the next 10 years.

Researchers found:

  • Participants with the most heart disease risks performed 50 percent worse on cognitive tests as compared to participants with the lowest risk profile.
  • The overall Framingham Risk Score, age, diabetes, bad cholesterol and smoking were negatively linked to poor cognitive scores.
  • Compared to non-smoking participants, those who smoked one to 15 cigarettes daily had a decrease in cognitive score of 2.41 points and those smoking more than 16 cigarettes daily had a decrease of 3.43 points. The memory scores had a similar association.
  • Two risk factors -- smoking and diabetes -- were strong determinants of cognitive function.

"There clearly is a dose response among smokers, with heavy smokers having a lower cognitive function than light or non-smokers," Joosten said. "It is likely that smoking cessation has a beneficial effect on cognitive function."

Health professionals need to be aware of cognitive function in patients with risk factors for cardiovascular disease. Cardiovascular risk factors, especially those that are modifiable like smoking and obesity, need ongoing attention from the medical profession, government and food industry, she said. "Smoking cessation programs might not only prevent cancer, stroke and cardiovascular events, but also cognitive damage."
