Today Facebook reported its second-quarter financial performance, including revenue of $1.81 billion. Analysts had expected Facebook to earn $0.14 per share on a top line of $1.62 billion. The company’s revenue figure released today is an all time quarterly high for the firm. Facebook’s second-quarter revenue is up 53 percent on a year-over-year basis. Analysts had expected a 37 percent increase. In the quarter, Facebook had a net income of $333?million.?In its most recent sequential quarter, the first of 2013, Facebook’s revenue totaled $1.46 billion, and it earned $0.12 per share. Mobile income as a percentage of ad revenue totaled 41 percent, up 11?percent from the preceding quarter, when it totaled 30?percent. In the final quarter of 2012, mobile ad income was but 24?percent of the total advertising top line. Facebook has proven that it can monetize its growing mobile usage in a big way. Investors will be satiated in that concern. Facebook later noted that mobile revenue will soon outstrip desktop incomes. The company also reaffirmed that Instagram will monetize in the future, largely through advertisements. Frankly, in my view the 41% figure is quite impressive, and unexpectedly strong. However, we should not take as indicative that all desktop Internet giants will be able to monetize at similar levels in mobile settings. Facebook data on its users is nearly without compare, and likely provides it with a key competitive advantage in how it can deliver targeted ads to users on the go. The majority of Facebook’s revenue comes from advertising-related income. However, its payments and fee revenue totaled?$214 million during the quarter, up 11 percent on a year-over-year basis. On the usage front, Facebook demonstrated strong growth, with its daily active user tally rising 27?percent on a yearly basis to 699 million. Monthly active users now total 1.15 billion for Facebook, up 21?percent when compared to the second quarter of 2012. Finally, mobile monthly active users were up 51?percent compared to 2012, to 819 million. For more on Facebook’s usage metrics, TechCrunch’s Josh Constine has the fully skinny. Facebook’s capital expenses were down in the quarter, but it continues to suffer from margin pressure. In the second quarter, Facebook’s operating margin was 31?percent. During the company’s earnings call, Facebook’s CEO Mark Zuckerberg stated that teen engagement remains quite high?on the social service. According to the company, engagement among teens in the United States, penetration is all but complete, and
COLOMBO, July 23 (Reuters) - Rain and an on-field injury which prevented South African opener Hashim Amla from batting spurred Sri Lanka to a 17-run win under the Duckworth-Lewis method in the second one-dayer on Tuesday.
Sri Lanka grabbed a 2-0 lead in the five-match series after rain played havoc with the schedule, delaying the start by 25 minutes before forcing further interruptions.
The hosts elected to bat first but struggled to reach 223 for nine wickets on a sluggish pitch.
South Africa were set a target of 176 from 29 overs under the D/L method but they suffered a major setback even before they could start their run chase as Amla injured his knee while fielding and could not open the batting.
Amla, who slipped and fell on his knee in the 43rd over, was taken to hospital for a precautionary x-ray.
In his absence, Robin Peterson was pushed up the order and while that meant he became the first spinner to open both the batting and the bowling for his country, he could not stop South Africa floundering as he perished in the opening over for three.
They slumped to 104 for five after 21 overs when rain returned for a third time with the tourists 17 runs short of a revised victory target of 121.
The wet pitch was hardly ideal for a limited-overs game and the 43 runs apiece from Sri Lanka's Tillakaratne Dilshan and Dinesh Chandimal were the highest individual scores.
Dilshan's knock off 64 balls comprised one four and no batsman struck a six during the 71 overs.
The wet outfield did not help either because many of the shots which would have gone for four stopped short of the ropes.
Man of the match Chandimal took chances and managed four fours off 51 balls while team mate Kumar Sangakkara made 37 off 60 balls with six fours but boundaries were hard to come by.
Morne Morkel (3-34) was again South Africa's top bowler picking up both openers and the wicket of Chandimal.
South Africa's fielding was an improvement on the first ODI but it came at a price when Amla jarred his left knee trying to stop a Chandimal boundary and was helped off the field limping.
Amla had returned to the side in place of Colin Ingram after missing the first ODI with a stiff neck.
The teams will now travel to Pallekele for the third and fourth ODIs scheduled for Friday and Sunday. (Editing by Ken Ferris and Pritha Sarkar)
New strategy for fiber tracking in human brainPublic release date: 23-Jul-2013 [ | E-mail | Share ]

Diffusion tensor imaging fiber tracking with reliable tracking orientation and flexible step size can show white matter fiber bundles in the healthy corpus callosum. Researchers used two sets of human data to assess the performance of this method; one was from a healthy volunteer and the other from a patient with low-grade glioma. Results verified that this method was superior to the single-tensor Fiber Assignment by Continuous Tracking and the two-tensor eXtended Streamline Tractography for showing detailed images of fiber bundles. A recent study published in the Neural Regeneration Research (Vol. 8, No. 16, 2013) proposed this new method of reliable tracking orientation and flexible step size fiber tracking. This new directional strategy was defined to select one optimal tracking orientation from each directional set, which was based on the single-tensor model and the two-tensor model.

[unable to retrieve full-text content]Until recently, how EoE, a food allergy-associated disease, developed was unclear, but a new study shows that a type of rare immune cell and specific reactions to allergenic foods team up -- in a bad way. This association does point to new ways to possibly treat inflammation associated with EoE.
Over the past 19 seasons, the girls of "America's Next Top Model" have basically done it all -- from massive makeover meltdowns to girl-on-girl catfights. So what does creator and star Tyra Banks do when the girls can no longer deliver high ratings? Bring in the boys!

Men are coming to "America's Next Top Model."
For the first time ever, the upcoming season of "Top Model" will feature male models. Eight men and eight women will live together and compete for a national ad campaign with GUESS, a spread in Nylon magazine and a modeling contract with Next Model Management.
"It's guys and girls," one female contestant says in the season's trailer. "What could be more dramatic than that?"
"Girls, you think you run the show but you have no idea what you're getting yourselves into with the guys," offers one of the buffed and bronzed male contestants.
Last season, the show underwent some major revamping, including contestants who were all college students, a new judges' panel and a move to a new night, but the tweaks failed to bring the show back to its glory days of high ratings.
"This cycle will explore the similarities and differences that male and female models face in the pursuit of their careers, bringing on experts and celebrities to mentor and challenge them each week," the show's website claims. "There will be more than a little opportunity for rivalry, flirtation and romance."
Will it be enough to save "Top Model?" We'll have to wait until the new season premieres on Friday, Aug. 2 to find out.
