Arias' Lawyer Shows Ex-Boyfriend's Lewd Photos

Accused murderer Jodi Arias was kept away from the Mormon friends of her lover Travis Alexander and their torrid sex affair was kept secret by Alexander, even as he sent lewd photos of himself to her online, according to court testimony today.

The testimony in Arias' trial for killing Alexander in 2008 was intended to bolster the defense's argument that she killed him in self defense, that Alexander was a sexual deviant who treated Arias as his "dirty little secret."

Arias' attorneys introduced as evidence photos that Alexander took of his penis and sent to Arias, part of a string of graphic messages and sexual phone calls the two engaged in while Alexander, an elder in the Mormon church, was supposed to be chaste.

Today's witness was the latest in a string called by the defense, including Alexander's former girlfriend Lisa Daidone, who told the court that Alexander had professed to be a virgin.

Daniel Freeman continued his testimony today, describing how he was a friend of both Arias and Alexander but that Alexander kept Arias distanced from his Mormon pals.

"Travis had made more friends at (the Mormon) ward, and had (Ultimate Fighting Championship) fight nights at his house many times, and Jodi was in town, but she wasn't there," Freeman said.

"There was that group of friends, them and Jodi, two different groups, and so Lisa [Daidone] and friends from church were there, but Jodi wasn't there," Freeman said.

Alexander's behavior, the defense hopes to prove, shows that he mistreated Arias.

Arias, 32, is on trial for murdering Alexander, whom she dated for a year and continued to have a sexual relationship for a year after that. Her attorneys claim that Alexander was abusive and controlling toward Arias, and that she was forced to kill him.

Freeman described how he took a trip with his sister, Alexander, and Arias, and how Alexander had asked him to come along so that he and Arias "would not get physical."

"I don't know that I can say he didn't want to be alone with her, but he liked that when I was there, and my sister was there. They weren't as physical," Freeman said.

Freeman admitted that he had no idea Alexander and Arias had been having a sexual relationship the entire time they were together. He said Alexander never mentioned that to his friends.

In fact, Freeman noted that Alexander was considered to be a church elder when he baptized Arias into the Church of Latter-Day Saints. Both a church elder and a convert were expected to abide by the church's strict law of chastity, which banned any sexual relations outside of marriage.

"One thing people give up in this baptism process was sex," prosecutor Juan Martinez said. "Did you know she was having oral sex with Mr. Alexander at the time of her baptism? Would that be an insincere baptism?"

"She would not be ready to be baptized in that case," Freeman said.

"You were asked about Miss Arias, whether she was worthy of baptism if she was performing oral sex, but what about the elder receiving oral sex?" defense attorney Kirk Nurmi said.

"They would not be worthy of performing that ordinance at that time until they had gone through repentance," Freeman said. "They would go to a discipline council and could face excommunication or a probation period or have their priesthood removed."

Freeman said that Alexander never confessed to having a sexual relationship with Arias.

Freeman's testimony came on the third day of the defense's attempt to paint Alexander as a controlling, sex-obsessed liar who was cruel to Arias. Other witnesses have said that Alexander cheated on other women he dated with Arias, and lied to his friends and family about their relationship.

The defense also had Freeman point out that Alexander was strong and fit. They are expected to conclude that Alexander was physically threatening Arias when she killed him.

More people volunteering their services to help others: survey

SINGAPORE: More people are giving their time and making the effort to help others, with one in three serving as volunteers in 2012.

A survey by the National Volunteer & Philanthropy Centre (NVPC) found that about 32 per cent of its respondents were volunteers, which is the highest rate since it started the survey in 2000.

The same survey conducted in 2010 had 23 per cent.

The survey, conducted between July and September 2012, found that the increase was largely driven by the interest in informal volunteering.

This refers to activities like reading to the child of a needy neighbour, instead of being part of a formal organisation.

The survey also found that individual donations remained steady at about $1.1 billion in 2012, compared with $1.07 billion in 2010.

Those who earned below $1,000 a month donated a bigger share of their income - at 1.8 per cent.

That's higher than the 0.5 per cent for those earning between $5,000 and below $6,000.

More than 1,500 people took part in the survey, which did not include compulsory community work by students.

Tumblr avoids porn label and adds mature rating to iOS app

Tumblr's iPhone app.

Tumblr looks to be trying to avoid the porn-war that recently harangued the 500px photo app and Twitter's Vine app.

The microblogging company threw up a 17-and-over age warning for its iOS app for all new users and any people updating their app to the 3.2.4 version, which was released today.

"You must be at least 17 years old to download this app," Tumblr writes in its description of the app in the iTunes App Store, because it contains "Frequent/Intense Sexual Content or Nudity."

The app's upgrade says only that it will carry out "small bug fixes." However, when users click on the 3.2.4 version, they're forced to confirm they are over the age of 17. "Tumblr contains age-restricted material," the app says when upgrading. "Tap OK to confirm that you are 17 or over. Your content will then begin downloading immediately."

It's unclear exactly why Tumblr changed its app to contain a mature rating. But it's no secret that certain blogs on the site contain "sexual content" and "nudity." In an interview last June, Tumblr founder David Karp noted that 2 percent to 4 percent of the traffic on Tumblr is porn-related.

Tumblr's 17+ rating comes as 500px and Vine have been scrutinized for making porn easily accessible. When Twitter released the Vine app last week, many users quickly found a handful of videos featuring male exhibitionism and other activity. Apple quickly stopped promoting Vine in its App Store.

500px had an even more severe reprimand. After complaints of the app containing pornographic images and material, Apple pulled it from
iTunes. Now that 500px has added warnings and a 17+ rating, Apple allowed it back into the App Store.

Maybe Tumblr is acting preemptively with its new 17+ rating. CNET contacted Tumblr for comment. We'll update the story when we get more information.

New Theory on How Homing Pigeons Find Home

Jane J. Lee

Homing pigeons (Columba livia) have been prized for their navigational abilities for thousands of years. They've served as messengers during war, as a means of long-distance communication, and as prized athletes in international races.

But there are places around the world that seem to confuse these birds—areas where they repeatedly vanish in the wrong direction or scatter on random headings rather than fly straight home, said Jon Hagstrum, a geophysicist who authored a study that may help researchers understand how homing pigeons navigate.

Hagstrum's paper, published online Wednesday in the Journal of Experimental Biology, proposes an intriguing theory for homing pigeon disorientation—that the birds are following ultralow frequency sounds back towards their lofts and that disruptions in their ability to "hear" home is what screws them up.

Called infrasound, these sound waves propagate at frequencies well below the range audible to people, but pigeons can pick them up, said Hagstrum, who works at the U.S. Geological Survey in Menlo Park, California.

"They're using sound to image the terrain [surrounding] their loft," he said. "It's like us visually recognizing our house using our eyes."

Homeward Bound?

For years, scientists have struggled to explain carrier pigeons' directional challenges in certain areas, known as release-site biases.

This "map" issue, or a pigeon's ability to tell where it is in relation to where it wants to go, is different from the bird's compass system, which tells it which direction it's headed in. (Learn about how other animals navigate.)

"We know a lot about pigeon compass systems, but what has been controversial, even to this day, has been their map [system]," said Cordula Mora, an animal behavior researcher at Bowling Green State University in Ohio who was not involved in the study.

Until now, the two main theories say that pigeons rely either on their sense of smell to find their way home or that they follow the Earth's magnetic field lines, she said.

If something screwed up their sense of smell or their ability to follow those fields, the thinking has been, that could explain why pigeons got lost in certain areas.

But neither explanation made sense to Hagstrum, a geologist who grew interested in pigeons after attending an undergraduate lecture by Cornell biologist William Keeton. Keeton, who studied homing pigeons' navigation abilities, described some release-site biases in his pigeons and Hagstrum was hooked.

"I was just stunned and amazed and fascinated," said Hagstrum. "I understand we don't get dark matter or quantum mechanics, but bird [navigation]?"

So Hagstrum decided to look at Keeton's pigeon release data from three sites in upstate New York. At Castor Hill and Jersey Hill, the birds would repeatedly fly in the wrong direction or head off randomly when trying to return to their loft at Cornell University, even though they had no problems at other locations. At a third site near the town of Weedsport, young pigeons would head off in a different direction from older birds.

There were also certain days when the Cornell pigeons could find their way back home from these areas without any problems.

At the same time, homing pigeons from other lofts released at Castor Hill, Jersey Hill, and near Weedsport, would fly home just fine.

Sound Shadows

Hagstrum knew that homing pigeons could hear sounds as low as 0.05 hertz, low enough to pick up infrasounds that were down around 0.1 or 0.2 hertz. So he decided to map out what these low-frequency sound waves would have looked like on an average day, and on the days when the pigeons could home correctly from Jersey Hill.

He found that due to atmospheric conditions and local terrain, Jersey Hill normally sits in a sound shadow in relation to the Cornell loft. Little to none of the infrasounds from the area around the loft reached Jersey Hill except on one day when changing wind patterns and temperature inversions permitted.

That happened to match a day when the Cornell pigeons had no problem returning home.

"I could see how the topography was affecting the sound and how the weather was affecting the sound [transmission]," Hagstrum said. "It started to explain all these mysteries."

The terrain between the loft and Jersey Hill, combined with normal atmospheric conditions, bounced infrasounds up and over these areas.

Some infrasound would still reach Castor Hill, but due to nearby hills and valleys, the sound waves approached from the west and southwest, even though the Cornell loft is situated south-southwest of Castor Hill.

Records show that younger, inexperienced pigeons released at Castor Hill would sometimes fly west while older birds headed southwest, presumably following infrasounds from their loft.

Hagstrum's model found that infrasound normally arrived at the Weedsport site from the south. But one day of abnormal weather conditions, combined with a local river valley, resulted in infrasound that arrived at Weedsport from the Cornell loft from the southeast.

Multiple Maps

"What [Hagstrum] has found for those areas are a possible explanation for the [pigeon] behavior at these sites," said Bowling Green State's Mora. But she cautions against extrapolating these results to all homing pigeons.

Some of Mora's work supports the theory that homing pigeons use magnetic field lines to find their way home.

What homing pigeons are using as their map probably depends on where they're raised, she said. "In some places it may be infrasound, and in other places [a sense of smell] may be the way to go."

Hagstrum's next steps are to figure out how large an area the pigeons are listening to. He's also talking to the Navy and Air Force, who are interested in his work. "Right now we use GPS to navigate," he said. But if those satellites were compromised, "we'd be out of luck." Pigeons navigate from point to point without any problems, he said.

No Device Eliminates Concussion Risk, Experts Say

As the long-term consequences of concussions become clearer, a cottage industry has popped up to sell athletes and worried parents products designed to mitigate risks of concussions that even helmets cannot prevent.

Despite the bold claims of some companies, however, many experts say the Holy Grail in contact sports -- a device that prevents concussions -- simply does not exist. Indeed, experts say, there is no proof that any current device significantly reduces the risk of concussions beyond the protections already provided by helmets.

"Nightline" found several products for sale online that aim to reduce the risk of concussions or even alert parents and coaches when a kid has supposedly taken a concussion-level hit. The claims the manufacturers make are often breathtakingly reassuring.

Concern about the risk of concussion is mounting at every level of the gridiron from the NFL to colleges and even high schools. Concussions are the most common injury among high school football players.

Jennifer Branin, whose son Tyler Branin is one of the stars of the Woodbridge Warriors high school football team in Irvine, Calif., said "it was scary" the first time he had a concussion.

"He had lost his balance on the field," she said. "He got up and tried to continue, but couldn't keep his balance."

Junior Seau Had Brain Disease, Researchers Say Watch Video

She said the effects of the concussion lingered, causing Tyler to miss a week of school and football practice. Even months later, he complained of difficulty concentrating in class.

Parents such as Jennifer Branin, who is president of the team's booster club, and her husband, Andy Branin, a former college football player himself, were looking for a way to support their son's desire to play football while also keeping him safe.

"He wants to play and, as a mom, you may want to put bubble-wrap around them and protect them forever, but that's not going to happen," she said.

So Jennifer Branin decided to do something. She raised money to buy the team helmet inserts by Unequal Technologies for added protection.

Unequal Technologies, one of the highest profile players in this new market, described its product explicitly on the box as "Concussion Reduction Technology," or "CRT." It is a strip of composite material including bullet-proof Kevlar that is designed to stick inside the helmet as a liner to the existing helmet pads.

Unequal Technologies uses its material in products ranging from padded sleeves to shin guards. The company counts NFL players and X-Games athletes among its fans.

On board as paid spokesmen are Philadelphia Eagles quarterback Michael Vick and James Harrison, a linebacker for the Pittsburgh Steelers. Harrison is one of the hardest-hitting guys in the NFL and said he uses Unequal Technology's liners in his helmet.

"I don't know what it's made of but it works," Harrison says in one of Unequal's promotional videos. "I really don't feel like I'm taking a risk."

Vick wasn't wearing the CRT product when he suffered a season-ending concussion in November, but he has since promised that he will be wearing it when he returns to the field next season.

Rob Vito, founder and CEO of the Kennett Square, Pa.-based company, said he worked with scientists to create a military-grade composite material that can help protect athletes from all kinds of injuries from head to toe.

Talent Development Alliance formed to tap into workforce training in China market

SINGAPORE: Singapore has formed a Talent Development Alliance (TDA) to help the country's companies gain a stronger foothold in the China market through education and training.

Driven by IE Singapore, the alliance is the first of its kind in the industry in Singapore with seven institutions from the public and private sectors - Civil Service College, ITE Education Services, NTUC LearningHub, Nanyang Technological University, National University of Singapore and Singapore Management University.

A Memorandum of Understanding was signed on Wednesday.

IE Singapore said as China's economy continues to move from one that's driven by investments to one that's based on consumption, demand in the education and training sectors will grow exponentially.

China's workforce will need skills upgrading and higher education to support this development.

Singapore companies, with their forte in the services sector, as well as in education and training, can leverage these developments to contribute to China's growth.

Michael Dell to use personal funds to seek majority control -- report

James Martin/CNET)

Just weeks after reports surfaced that Dell was looking to go private, the company's founder appears willing to put his personal funds where his mouth is.

Michael Dell may kick in equity financing of $500 million to $1 billion combined with his 15.7 percent stake in the company to seek majority control of the company, according to Bloomberg. That would push his ownership stake past 50 percent.

With the investment, Dell would be contributing more than half of the total $8 billion to $9 billion equity check. The remainder of the takeover would be financed by debt and "possibly some of the $11 billion of cash Dell reported it had as of September 30," according to Bloomberg.

This follows on the heels of reports that Microsoft may contribute $1 billion to $3 billion and was in talks with Silver Lake Partners to help take Dell private.

However, the WSJ today reported that Microsoft's role in the new company has been a sticking point in negotiations. Though the deal is still expected to stay on track, Microsoft wants to have a say in some of Dell's operations rather than just being a source of funding, according to the WSJ's sources.

Dell, a one-time leading PC maker, has hit hard times of late. The company's stock has continued to lose value as it defends itself against rivals, and despite the many acquisitions it's made over the past several years, there are concerns about how fast those businesses are taking off. Some industry watchers are hoping that going private could give it the reboot that it needs.

Timbuktu’s vulnerable manuscripts are city’s "gold"

French and Malian troops surrounded Timbuktu on Monday and began combing the labyrinthine city for Islamist fighters. Witnesses, however, said the Islamists, who claim an affiliation to al Qaeda and had imposed a Taliban-style rule in the northern Malian city over the last ten months, slipped into the desert a few days earlier.

But before fleeing, the militants reportedly set fire to several buildings and many rare manuscripts. There are conflicting reports as to how many manuscripts were actually destroyed. (Video: Roots of the Mali Crisis.)

On Monday, Sky News posted an interview with a man identifying himself as an employee of the Ahmed Baba Institute, a government-run repository for rare books and manuscripts, the oldest of which date back to the city's founding in the 12th century. The man said some 3,000 of the institute's 20,000 manuscripts had been destroyed or looted by the Islamists.

Video showed what appeared to be a large pile of charred manuscripts and the special boxes made to preserve them in front of one of the institute's buildings.

However, a member of the University of Cape Town Timbuktu Manuscript Project told eNews Channel Africa on Tuesday that he had spoken with the director of the Ahmed Baba Institute, Mahmoud Zouber, who said that nearly all of its manuscripts had been removed from the buildings and taken to secure locations months earlier. (Read "The Telltale Scribes of Timbuktu" in National Geographic magazine.)

A Written Legacy

The written word is deeply rooted in Timbuktu's rich history. The city emerged as a wealthy center of trade, Islam, and learning during the 13th century, attracting a number of Sufi religious scholars. They in turn took on students, forming schools affiliated with's Timbuktu's three main mosques.

The scholars imported parchment and vellum manuscripts via the caravan system that connected northern Africa with the Mediterranean and Arabia. Wealthy families had the documents copied and illuminated by local scribes, building extensive libraries containing works of religion, art, mathematics, medicine, astronomy, history, geography, and culture.

"The manuscripts are the city's real gold," said Mohammed Aghali, a tour guide from Timbuktu. "The manuscripts, our mosques, and our history—these are our treasures. Without them, what is Timbuktu?"

This isn't the first time that an occupying army has threatened Timbuktu's cultural heritage. The Moroccan army invaded the city in 1591 to take control of the gold trade. In the process of securing the city, they killed or deported most of Timbuktu's scholars, including the city's most famous teacher, Ahmed Baba al Massufi, who was held in exile in Marrakesh for many years and forced to teach in a pasha's court. He finally returned to Timbuktu in 1611, and it is for him that the Ahmed Baba Institute was named.

Hiding the Texts

In addition to the Ahmed Baba Institute, Timbuktu is home to more than 60 private libraries, some with collections containing several thousand manuscripts and others with only a precious handful. (Read about the fall of Timbuktu.)

Sidi Ahmed, a reporter based in Timbuktu who recently fled to the Malian capital Bamako, said Monday that nearly all the libraries, including the world-renowned Mamma Haidara and the Fondo Kati libraries, had secreted their collections before the Islamist forces had taken the city.

"The people here have long memories," he said. "They are used to hiding their manuscripts. They go into the desert and bury them until it is safe."

Though it appears most of the manuscripts are safe, the Islamists' occupation took a heavy toll on Timbuktu.

Women were flogged for not covering their hair or wearing bright colors. Girls were forbidden from attending school, and boys were recruited into the fighters' ranks.

Music was banned. Local imams who dared speak out against the occupiers were barred from speaking in their mosques. In a move reminiscent of the Taliban's destruction of Afghanistan's famous Bamiyan Buddha sculptures, Islamist fighters bulldozed 14 ancient mud-brick mausoleums and cemeteries that held the remains of revered Sufi saints.

A spokesman for the Islamists said it was "un-Islamic" for locals to "worship idols."
