Mauritania army raid killed al-Qaida group leader (AP)

NOUAKCHOTT, Mauritania ? A senior military official in Mauritania's army says soldiers killed a leader of al-Qaida's North Africa affiliate during an air raid this week.

The colonel who spoke on the condition of anonymity following military protocol said late Friday that Tiyib Ould Sidi Ali has been eliminated. He said that Ali was a leader for al-Qaida in the Islamic Maghreb and was wanted for his role in a failed bombing attempt on the capital in February, and an attack against the Israeli Embassy in Mauritania in 2008.

Mauritania's army said its soldiers conducted an air raid in the Wagadou Forest just across the border in the nation of Mali on Thursday because AQIM, which is based there, was preparing to mount an attack on Mauritanian soil.

AQIM is an Algerian-born terrorist group that joined with al-Qaida in 2006 and has become a security threat in northwestern Africa.

(This version Corrects that Tiyib is first name, Ali is last.)

Toshiba Satellite P755-S5390


Sometimes all you need is a computer that can get things done. That description definitely applies to the Toshiba Satellite P755-S5390 ($799.99 list at Staples), a good-size laptop with an eye-catching design and some forward-thinking hardware that propels it to success at almost any everyday task you can throw at it short of gaming. Its battery life leaves something to be desired, but aside from that it?s a surprisingly powerful and well-rounded system that just narrowly misses out on the top tier of mainstream models.

Design
Weighing 5.6 pounds and measuring 1.1 by 13.4 by 9 inches (HWD), the P755-S5390 is about average in terms of portability. Toshiba calls the color of its plastic chassis ?Platinum,? but we call that optimistic: Think of it as a shiny dark gray with a raised and textured horizontal pattern (which Toshiba also dubs its Fusion X2 Finish) gracing the lid and palm rest; the striping extends to the keyboard deck and the touch pad, too, though they look much darker and more matte in style. Also on the lid you?ll find a silvery Toshiba logo; extending around edge of the lid and the inside of the laptop is a smooth and shiny border. The bezel surrounding the 15.6-inch widescreen 1,366-by-768 display (in which there is, of course, a webcam) and the chiclet-style keys are regular black, with the latter bearing subdued light-gray printing rather than a blaring white.

You do get that color, however, when you turn on the laptop. You'll see it in the system power and activity lights, a strip on the touch pad, and the Satellite logo on the lower-left corner. It's also prominent in the row of media-control and other laptop-function keys located near the display hinge: one starts the Toshiba eco Utility, one toggles the wireless on and off, one plays or pauses your media, one mutes the sound, and a strip lets you adjust the volume).

A nice addition to the keyboard is a full-size number pad; the space bar, alas, is unusually short and squat in design, which can occasionally make it difficult to press. Located above the touch pad is a button that deactivates it, and the mouse buttons are located below; they?re soft and only moderately clicky, but as part of the design scheme they?re coated with the same material as the slick outside border of the laptop, which can make your fingers slide across them.

Features
The Intel Core i7-2670QM processor in the P755-S5390 is an especially robust chip: It has four processing cores that can divide into eight threads by way of Intel?s Hyper-Threading technology, and it has a standard clock speed of 2.2GHz that can rise to as much as 3.1GHz when Turbo Boost is activated. As a member of Intel?s second-generation Core (aka ?Sandy Bridge?) family, this CPU also gives you access to that line?s full swath of features, including Quick Sync Video (for accelerated media format conversions) and Wireless Display 2.0 (for streaming content to your HDTV if you own?a Netgear Push2TV adapter).

Rounding out the components are 6GB of DDR3 RAM that?s upgradable to 8GB; a 640GB hard drive; 802.11b/g/n wireless networking; and built-in Harman Kardon stereo speakers. On the left edge of the system you?ll find VGA and HDMI ports for outputting video to an external display, an Ethernet jack, and two USB ports: one 2.0 and one the faster 3.0. A multiformat card reader is positioned at the very center of the laptop?s front edge; on the right edge are the headphone and microphone jacks, two USB 2.0 ports, and the DVD burner.

Preinstalled on the hard drive are the Windows 7 Home Premium operating system, and some additional software items you may or may not find useful: Windows Live Essentials, a 30-day trial of Norton Internet Security 2012, Microsoft Office Starter 2010, Skype, and the expected swath of Toshiba tools and utilities.

Customers who buy this system from Staples can avail themselves of several services the retailer offers. This includes setting the new system up, data transfer from your old PC to your new one, software installation, and tech support and protection plans that range in price from $14.99 to $169.99.

Performance
Toshiba Satellite P755-S5390The P755-S5390 is a bit difficult to categorize in terms of performance. Though the laptop?s price places it squarely in the mainstream category, its processor is a fair sight better than what we usually see in this class?but the system lacks the robust rounder edges we?d usually use to identify a desktop replacement laptop. So compared with other midrange systems, the P755-S5390 comes out on top in all cases, even against our Editors? Choice Asus U46E-BAL5 ($699.99 list, 4.5 stars)?and the more gaming-oriented, Sandy Bridge version of the HP Envy 14 ($1,079.99 direct, 4 stars). It nabbed a straight 2,400 in our PCMark 7 overall performance test, whereas the Asus U46E-BAL5 reached only 2,215; the P755-S5390?s times of 1 minute 31 seconds in Handbrake and 3:39 in Adobe Photoshop CS5, and its score of 5.35 in CineBench R11.5, were markedly better than what we saw from any other similar system we tested.

Even more disappointing were its gaming capabilities. The P755-S5390 could never get above (or even close to) our 30-frames-per-second (fps) threshold for smooth playability; it cracked into the very low 20fps on both our Crysis and Lost Planet 2 tests (at 1,024-by-768 resolution, with medium details), but no higher. In both cases, these numbers were better than those of the Asus U46E-BAL5, but the HP Envy 14 did much better in Crysis (45.5fps) and in our 3DMark 06 video benchmark test (7,751 versus 4,992 for the P755-S5390 at 1,024 by 768; and 6,509 versus 4,139 at the systems? native resolutions).

Battery life, on the other hand, was far from the P755-S5390?s strong suit. Loaded with its standard 48Wh battery, it only lasted 4 hours 11 minutes during our MobileMark 2007 battery-rundown test?more than an hour shorter than what you get with the HP Envy (5:15) and less than half what the Samsung QX411-W01 can deliver (a stunning 8:48). Even looked at against desktop replacement systems it?s a poor showing?the lowest amount of life among them comes from the most recent 15-inch Apple MacBook Pro ($2,199.99 direct, 4 stars)?and even that ekes out 4:40.

Unlike our Editors? Choice, the Asus U46E-BAL5, the Toshiba Satellite P755-S5390 isn?t intricately appointed in every area: You won?t find on it the Asus U46E-BAL5?s larger hard drive, more RAM, WiMAX, remarkable longevity when not plugged in, or lower price. So we have to let the Asus U46E-BAL5 retain its edge, despite the P755-S5390?s superior performance on all our productivity tests. Even so, the P755-S5390 stands out from the mainstream crowd and is absolutely worth considering if you have a lot of work to do?and quickly.

Murdoch to pay $3.2 million to schoolgirl's family (AP)

LONDON ? Rupert Murdoch's company said Friday it has agreed to pay 2 million pounds ($3.2 million) to the family of a murdered schoolgirl whose phone was hacked by the tabloid News of the World.

News International and the family of Milly Dowler confirmed the settlement in a joint statement.

Murdoch shut down the 168-year-old News of the World in July after evidence emerged that its reporters had eavesdropped on the telephone voice mail messages of the 13-year-old who disappeared in 2002 and was later found murdered.

The statement said Murdoch also will donate 1 million pounds ($1.6 million) to charities chosen by the Dowler family.

"Nothing that has been agreed will ever bring back Milly or undo the traumas of her disappearance and the horrendous murder trial earlier this year," the Dowlers said in the statement. "The only way that a fitting tribute could be agreed was to ensure that a very substantial donation to charity was made in Milly's memory. We hope that projects will be undertaken so that some good can come from this."

The revelation that reporters eavesdropped on Milly Dowler's voice mail messages while police were searching for her ? and mounting evidence that phone hacking was routine at the newspaper ? shook Murdoch's media empire, and sent tremors through Britain's political, police and media establishments.

The scandal has forced the resignation of two of London's top police officers, ousted executives at Murdoch's News Corp. and claimed the job of Prime Minister David Cameron's former spin doctor, Andy Coulson, an ex-News of the World editor.

Murdoch's global News Corp. has expressed contrition, launched an internal inquiry and set aside 20 million pounds ($32 million) to compensate victims, who could number in their hundreds. Detectives have informed more than 450 people that they might have been spied on by the newspaper.

China's military in diplomatic charm offensive (AP)

BEIJING ? China may make its neighbors nervous with its robust military build-up, but it's also increasingly using the army as part of its charm offensive abroad.

The People's Liberation Army, in a cultural shift for an institution known for strident nationalism and unbending loyalty to the Communist Party, is expanding overseas aid missions and military exchanges in a major way. It sent 50 medics to flood-hit Pakistan this week and dispatched a hospital ship last month on a 105-day trip to poor nations in the Caribbean ? right in America's backyard.

The diplomatic push, part of a larger global campaign by the Chinese government, aims to portray China as a responsible rising power, while softening the image of the 2.3 million-member military and boosting its ties with other nations' armed forces.

"It's has been a big step for them, but China appreciates this as a part of the normal practices of respected major powers in their relations with other countries," said Ron Huisken of the Australian National University's Strategic and Defense Studies Center.

China's "soft power" drive also includes foreign aid, cultural exchange and a massive expansion of state television to reach foreign audiences ? all attempts to win friends and correct what China considers to be a biased Western portrayal of it.

The military took its first big stab at overseas disaster relief last year, sending helicopters to help out with floods in Pakistan. Last month, the air force flew 7,000 tents to the once-again flood-ravaged country and it is also shipping aid to flooded areas of Thailand.

The People's Liberation Army, or PLA, has also become the biggest contributor of manpower to U.N. peace keeping missions, and its navy is part of a multinational anti-piracy flotilla off the coast of Somalia.

The Peace Ark hospital ship, which sailed to the Horn of Africa last year, set off on Sept. 16 for Cuba, Jamaica, Trinidad and Tobago, and Costa Rica. More than 100 medical personnel are aboard for an operation dubbed Harmonious Mission 2011.

"The international community expects China to play such a role and that is part of China's foreign policy," said Xiong Zhiyong of the China Foreign Affairs University in Beijing.

Only recently has the PLA acquired the skills, equipement, and political will to carry out such missions.

Its previous inability to provide relief overseas was especially evident following the 2004 Asian tsunami.

While the U.S. Navy and other countries' militaries rapidly shipped in huge amounts of aid and personnel, and winning tremendous goodwill for their governments, China could do little more than send a medical team to Indonesia, along with tents and other supplies.

Overseas missions also help grow its ability to deal with domestic disasters, such as the massive 2008 Sichuan earthquake, Xiong said.

At home, students from across the developing world are increasingly coming to China to take two-year military command courses, while the PLA's University of Science and Technology has taken in a dozen army officer candidates from Laos, Mongolia, Turkmenistan and seven other countries.

The military's newspaper called that a sign the force is "integrating itself into the world with a much more open attitude."

Foreign military attaches are being granted more access to Chinese bases and training exercises, although much of that is carefully scripted. Top commanders have also began making more frequent visits abroad and participating in multinational forums such as the annual Shangri-La Dialogue in Singapore that attracts top defense officials from the U.S., Britain, and other major nations.

The exchanges are part of the PLA's effort to evolve into a modern force, right down to the introduction of smart new dress uniforms intended to break down the distinction between PLA officers and their Western counterparts.

The military has been upgrading its warplanes, ships and submarines, and began sea trials this summer on a refurbished Soviet aircraft carrier, demonstrating how a once-decrepit force seems determined to go toe-to-toe with the U.S. and other regional militaries.

While that modernization disconcerts the U.S. and China's neighbors, China says it's needed to defend its interests. Some analysts say military diplomacy is a way to show off its strength to potential rivals, while also joining in international relief efforts.

"There is little trust between China and the U.S. so China's recent response is to demonstrate its military capability, which also fits its commitment to helping the global community," said Ni Lexiong, a military expert at Shanghai University of Political Science and Law.

Humanitarian missions such as the dispatch of a hospital ship to Cuba also deliver a signal of China's military resolve to its own public without risking actual confrontations with the U.S. or others, Ni said.

"The enormous public pressure requires a response and this doubly demonstrates the Chinese navy's logistical capability," Ni said.

The U.S. military for its part has been generally supportive of the PLA's humanitarian drive, saying that boosts transparency and chances for peaceful interactions.

"As the Chinese military develops the capability to deliver medical and humanitarian assistance beyond its immediate region, there will be opportunities for the United States and China to collaborate and share," the Pentagon said in its most recent report to Congress on China's armed forces.

But on military exchanges, the PLA has yet to grasp the intrinsic value of strong ties, said Australian expert Huisken, citing the recent suspension of exchanges with the Pentagon over U.S. arms sales to Taiwan. It's unclear what if any exchanges have so far been suspended or canceled.

"It remains a relatively superficial program," he said. "We still don't have a clue what their real aspirations are."

Why did Rick Perry call Herman Cain 'brother'? (The Week)

New York ? In this week's GOP presidential debate, the Texas governor called his black rival "brother" ? while referring to white candidate Mitt Romney as "sir"

Texas Gov. Rick Perry came out swinging at Mitt Romney in Tuesday night's GOP presidential debate in Las Vegas, but he struck a more jocular tone with Herman Cain. "Herman, I love you, brother, but let me tell you something," Perry said before criticizing Cain's 9-9-9 tax plan. Then, a moment later: "I'll bump plans with you, brother, and we'll see who has the best idea." Cain is the only black candidate in the GOP race, and the only candidate who got the "brother" treatment from Perry. The Texan called Romney "sir" several times, though in a somewhat disparaging way (watch video below). Perry spokesman Ray Sullivan insists that these nicknames have nothing to do with race, and that Perry is simply "a friendly fellow. He uses that kind of language." But what does it mean that he only used that "kind of language" with Cain?

Perry was just being cynical: Perry wasn't trying to create a race flap with his "brother" talk,?says Al Sharpton,?quoted in the?New York?Daily News. He was trying to fix one ? namely, the controversy over his family's "Niggerhead" hunting camp. On Tuesday night,?Perry "was openly trying to befriend the only black man on the stage." That's certainly a "cynical" way for Perry to try and improve his image after the "Niggerhead" flap ? but hardly racist.
"Rick Perry calls Herman Cain 'brother'...: Racial dig or friendly gesture?"

"Brother" is a southern evangelical thing: People will view this very differently in the North and the South,?says Nia-Malika Henderson in?The Washington Post.?And remember, Cain and Perry are both religious southerners. Perry has publicly called white churchgoers "brother," too, because "it is a Sunday morning greeting that both Perry and Cain, a preacher, have likely extended and routinely received before and after church service." It's a "term of endearment, shorthand for 'brothers in Christ.'"
"Rick Perry called Herman Cain 'brother.' Why?"

Regardless, Perry shouldn't have called Cain "brother": "Maybe it was a Christian dog whistle" on Perry's part, says Frank James at NPR. But plenty of other GOP candidates are also "well known for their Christian faith," and Perry didn't call them "brother." Fair or not, Perry's language set people's "nerves on edge" because "when a white man calls a black man 'brother' and if they are not actually brothers (think adoption), or in a Greek-letter fraternity, or soldiers... many a brotherized black man will immediately feel condescended to."
"Rick Perry 'brothers' Herman Cain and sets some nerves on edge"

New research links common RNA modification to obesity

ScienceDaily (Oct. 18, 2011) ? An international research team has discovered that a pervasive human RNA modification provides the physiological underpinning of the genetic regulatory process that contributes to obesity and type II diabetes.

European researchers showed in 2007 that the FTO gene was the major gene associated with obesity and type II diabetes, but the details of its physiological and cellular functioning remained unknown.

Now, a team led by University of Chicago chemistry professor Chuan He has demonstrated experimentally the importance of a reversible RNA modification process mediated by the FTO protein upon biological regulation. He and 10 co-authors from Chicago, China and England published the details of their finding in the Oct. 16 advance online edition of Nature Chemical Biology.

He and his colleagues have shown, for the first time, the existence of the reversible RNA modification process -- called methylation -- and that it potentially impacts protein expression and function through its action on a common RNA base: adenosine. The process is reversible because it can involve the addition or removal of a methyl group from adenosine. The team found that the FTO protein mediates cellular removal of the methyl group.

"An improved understanding of the normal functions of FTO, as exemplified by this work, could aid the development of novel anti-obesity therapies," said Stephen O'Rahilly, professor of clinical biochemistry and director of the Metabolic Research Laboratories at the University of Cambridge. O'Rahilly, a leading researcher in obesity and metabolic disease who also has studied FTO, was not directly involved in He's project.

"Variants around the FTO gene have consistently been associated with human obesity and artificial manipulation of the fto gene in mice clearly demonstrates that FTO plays a crucial role in the regulation of body weight," O'Rahilly explained. "However, the development of a deeper understanding of the normal biological role of FTO has been challenging."

Scientists already had demonstrated that FTO removes methyl groups from nucleic acids, but only on one rare type of DNA or RNA methylation. The new research from He and his colleagues shows that FTO also acts on the common messenger RNA modification called N6-methyladenosine, O'Rahilly said.

The paper arose from He's investigations of the AlkB family of proteins that act on nucleic acids. Based on this work, He and his collaborators proved that human cells exhibit reversible methylation of RNA bases, which significantly impact critical life processes.

Important but mysterious

Every human messenger RNA carries on average three to six methylations on adenosine. Scientists knew these methylations were extremely important but their function remained a mystery, He said. "For the first time, we show that these methylations are reversible and play a key role in human energy homeostasis," the process by which the body maintains a complex biochemical dynamic equilibrium.

The modification of N6-methyladenosine in messenger RNA is pervasive throughout the mammal kingdom and many other organisms. Despite its abundance, this modification's exact functional role remains unknown, He said. But his team's discovery strongly indicates that the modification has major roles in messenger RNA metabolism.

The finding may open a new research field -- RNA epigenetics -- for delving into the realm of biological regulatory processes, He said. The epigenetics of DNA and histones (proteins that package DNA in human cells) have become well-explored topics on the frontiers of biological research over the last 10 to 20 years. "It is safe to say 50 percent of biologists work on subjects related to epigenetics one way or another," He said.

DNA (deoxyribonucleic acid) for decades has reigned as king over biological research on epigenetics of nucleic acids, as He noted in the December 2010 issue of Nature Chemical Biology. RNA (ribonucleic acid) modification was regarded more as a vassal that merely fine-tunes gene expression and regulation, until this recent discovery, which confirms the speculation by He and others that RNA modification has secretly wielded a far greater genetic influence than anyone had previously suspected. That's why, as He wrote last year, "reversible RNA modification might represent another realm for biological regulation in the form of 'RNA epigenetics.'"
