More evidence suggests eating omega 3s and avoiding meat, dairy linked to preserving memory

Apr. 29, 2013 ? A University of Alabama at Birmingham (UAB) study suggests that the Mediterranean diet, which emphasizes consuming foods that contain omega-3 fatty acids found in fish, chicken and salad dressing, and avoiding saturated fats, meat and dairy foods, may be linked to preserving memory and thinking abilities. However, the same association was not found in people with diabetes. The research is published in the April 30, 2013, print issue of Neurology?, the medical journal of the American Academy of Neurology.

"Since there are no definitive treatments for most dementing illnesses, modifiable activities, such as diet, that may delay the onset of symptoms of dementia, are very important," said Georgios Tsivgoulis, M.D., a neurologist with UAB and the University of Athens, Greece.

Data came from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, housed at UAB. REGARDS enrolled 30,239 people ages 45 and older between January 2003 and October 2007, and it continues to follow them for health changes.

In this study, the largest yet done on the Mediterranean diet, dietary information from 17,478 African-Americans and Caucasians, average age of 64, was reviewed to see how closely they adhered to a Mediterranean diet. Study subjects also underwent tests that measured memory and thinking abilities over an average of four years. A total of 17 percent of the participants had diabetes.

The study found that in healthy people, those who more closely followed the Mediterranean diet were 19 percent less likely to develop problems with their thinking and memory skills. There was not a significant difference in declines between African-Americans and Caucasians. However, the Mediterranean diet was not associated with a lower risk of thinking and memory problems in people with diabetes.

"Diet is an important modifiable activity that could help in preserving cognitive functioning in late life," said Tsivgoulis. "However, it is only one of several important lifestyle activities that might play a role in late-life mental functioning. Exercise, avoiding obesity, not smoking cigarettes and taking medications for conditions like diabetes and hypertension are also important."

The study was supported by the National Institute of Neurological Disorders and Stroke, one of the National Institutes of Health, and the Department of Health and Human Services.

Patterned hearts: Bioengineers create rubber-like material bearing micropatterns for stronger, more elastic hearts

Apr. 29, 2013 ? A team of bioengineers at Brigham and Women's Hospital (BWH) is the first to report creating artificial heart tissue that closely mimics the functions of natural heart tissue through the use of human-based materials. Their work will advance how clinicians treat the damaging effects caused by heart disease, the leading cause of death in the United States.

"Scientists and clinicians alike are eager for new approaches to creating artificial heart tissues that resemble the native tissues as much as possible, in terms of physical properties and function," said Nasim Annabi, PhD, BWH Renal Division, first study author. "Current biomaterials used to repair hearts after a heart attack and other cardiovascular events lack suitable functionality and strength. We are introducing an alternative that has the mechanical properties and functions of native heart tissue."

The study was published online on April 26, 2013 in Advanced Functional Materials.

The researchers created MeTro gel-an advanced rubber-like material made from tropoelastin, the protein in human tissues that makes them elastic. The gel was then combined with microfabrication techniques to generate gels containing well-defined micropatterns for high elasticity.

The researchers then used these highly elastic micropatterned gels to create heart tissue that contained beating heart muscle cells.

"The micropatterned gel provides elastic mechanical support of natural heart muscle tissue as demonstrated by its ability to promote attachment, spreading, alignment, function and communication of heart muscle cells," said Annabi.

The researchers state that MeTro gel will provide a model for future studies on how heart cells behave. Moreover, the work lays the foundation for creating more elaborate 3D versions of heart tissue that will contain vascular networks.

"This can be achieved by assembling tandem layers of micropatterned MeTro gels seeded with heart muscles cells in different layers," said Ali Khademhosseini, PhD, BWH Division of Biomedical Engineering, co-senior study author. "As we continue to move forward with finding better ways to mend a broken heart, we hope the biomaterials we engineer will allow us to successfully address the limitations of current artificial tissues."

This research was supported by the National Institutes of Health (HL092836, DE019024, EB012597, AR057837, DE021468, HL099073, EB008392); National Health and Medical Research Council; CRC for Polymers; BHP-Billiton Fulbright Scholarship; National Science Foundation; Office of Naval Research Young National Investigator Award; Presidential Early Career Award for Scientists and Engineers; Australian Research Council; and Australian Defense Health Foundation and National Health and Medical Research Council.

Movie Reviews: 'The Big Wedding', 'Pain & Gain', 'Home Run'

Movie information aggregated from?MovieFone.com

The Big Wedding

"There?s not a bad performance in this movie. De Niro, Keaton and Sarandon are particularly good, what a surprise. But it feels as if all the guests at ?The Big Wedding? are wearing ID tags telling us their one Plot Point." Richard Roeper, Chicago Sun-Times.

"There is nothing about the movie that isn?t utterly predictable. You meet a character, and it?s immediately obvious what?s going to happen to him (or her). And then it happens. Maybe it?s meant to make you feel good about your deductive reasoning skills or something. But mostly it just makes you want to see something else."?Bill Goodykoontz, Arizona Republic.

Pain & Gain

"This is easily Bay?s best movie, the work of a filmmaker with a cracked sense of humor that he is able to share with the audience." Rene Rodriguez, Miami Herald.

"Yes, the canon invoked for this film is that of the Three Stooges, but it?s still not as magnificently berserk as they can be. Set your expectations carefully for this one." Louis Black, Austin Chronicle.

"Reese Witherspoon's unglamorous, understated supporting work recalls the kinds of films she made before becoming a movie star. Other recognizable faces include Sam Shepard, Joe Don Baker, Michael Shannon, and Sarah Paulson." James Berardinelli, ReelViews. Full Review

"It?s hard to believe Nichols thinks he can get away with all this and harder still to believe he does. It?s the quality of the attention that he brings ? his focus ? that makes his work so engrossing." David Edelstein, New York Magazine (Vulture). Full Review

The Place Beyond The Pines

"A riveting crime thriller, it's also a multi-generational familial saga that approaches Greek tragedy." Claudia Pulg, USA Today. Full Review

"Cool, violent, a cigarette dangling from his mouth, Gosling reprises his inexorable-loner routine from ?Drive.? Cianfrance and the screenwriters Ben Coccio and Darius Marder wrote thirty-seven drafts of the script, but gave him almost nothing to say. He rides, he smokes, he knocks over banks, he loves his baby, and that?s it." David Denby, The New Yorker. Full Review

Oblivion

"The good news: Here's a lavish, serious science-fiction picture, one that on occasion transcends big-budget hit-making convention to glance against grandeur...Which brings us to Tom Cruise, the not-necessarily-good news. However engaging its end-times mysteries, Oblivion is still a Tom Cruise movie." Alan Scherstuhl, Village Voice. Full Review

"One of the all-time great sports movies ? primarily because it's one of the all-time great sports stories." Steve Persall, Tampa Bay Times.

"42 is competent, occasionally rousing and historically respectful ? but it rarely rises above standard, old-fashioned biography fare. It?s a mostly unexceptional film about an exceptional man." Richard Roeper, Chicago Sun-Times.

"This Chris Sanders fellow knows how to craft a heart-warming animation, and if not for a few minor problems this would have had a legitimate shot at the best animated movie of 2013."?Laremy Legel, Film.com

"The movie is at its most interesting and amusing when riffing on how cavemen might have reacted to new experiences and ideas, like fire and shoes.

Olympus Has Fallen

"While Olympus Has Fallen breaks no major new ground in the political thriller genre, Fuqua has directed a sharp, very taut adventure that keeps you engrossed from start to finish." Bill Zwecker, Chicago Sun-Times.

"Perhaps every generation gets the movie stars it deserves. ?Olympus? has quite a bit to say about the current state of our country. Intentions aside, not all of it is entirely flattering." Elizabeth Weitzman, New York Daily News.

For first time, smart phones edge past feature phones

There were more smart phones shipped last quarter than low-end, "dumb" phones shipped, according to a new study.

By Steph Solis / April 26, 2013

In this file photo, a passerby takes a picture of an Apple Store in Sydney, Australia with a Samsung Galaxy phone. Smart phones surpassed feature phones in shipping numbers for the first time, in Q1 of 2013.

For the first time, more smart phones were shipped around the world than low-end, feature phones, according to the International Data Corporation.

' + google_ads[0].line3 + '

'; } else if (google_ads.length > 1) { ad_unit += ''; } } document.getElementById("ad_unit").innerHTML += ad_unit; google_adnum += google_ads.length; return; } var google_adnum = 0; google_ad_client = "pub-6743622525202572"; google_ad_output = 'js'; google_max_num_ads = '1'; google_feedback = "on"; google_ad_type = "text"; google_adtest = "on"; google_image_size = '230x105'; google_skip = '0'; // -->

The IDC?s first-quarter statistics show that out of the 216.2 million phones shipped, 51.6 percent were smart phones. These numbers mark an important milestone for the mobile-phone industry in an otherwise slow quarter.

?Phone users want computers in their pockets. The days where phones are used primarily to make phone calls and send text messages are quickly fading away," says Kevin Restivo, senior research analyst with IDC?s WorldWide Quarterly Mobile Phone Tracker, in a statement. "As a result, the balance of smart phone power has shifted to phone makers that are most dependent on smart phones."

In the past year, the global mobile phone market grew by 4 percent, according to the IDC statment. The market expanded by 41.6 percent compared to the 152.7 million units shipped in the first quarter of 2012, but it was 5.1 percent lower than the 227.8 million units shipped at the end of the year.

Samsung stayed at the top with more units than Apple, LG, and Chinese vendors Huawei and ZTE combined. Its success this quarter can be attributed in part to the new features and security innovations of the Galaxy S4.

The data also shows the emergence of Chinese companies among leading smart-phone vendors. While a year ago, Nokia, BlackBerry (formerly Research In Motion), and HTC dominated the top five list, they face competition from Chinese vendors such as Huawei and ZTE, as well as Coolpad and Lenovo.

Zack Whittaker?of ZDNet describes the numbers as a tipping point in which smart phones are becoming the norm, in both developed and emerging nations. However, he notes that feature phones will not vanish so quickly.

?It?s not to say the feature phone market is dead or even dying,? he writes. ?A tipping point, maybe, but there?s still a huge economy in building the not-so-smart phones.?

Carl Howe, vice president of the Yankee Group, echoes that sentiment, saying it?s clear that smart phones are on the rise, just not on when exactly they will surpass feature phones on sales, shipment, and ownership.

?Nobody?s going to debate that [smart phones] will surpass future [low-end] phone sales,? Mr. Howe says in a phone interview.

The bigger trend, however, is the growing complexity of the devices consumers carry in their pockets. Howe says it?s a game changer that has cultural implications, and potential opportunities for mobile phone companies to earn extra revenue.

The cultural implications can differ between emerging and developed nations, but it is clear that each society will see a number of trade-offs for smart phones, he says.

?The most interesting thing is that people consider them so essential that people are giving up essential things for them,? he says. ?One executive I know from a large computer firm went to Peru, and he was surprised to see people sleeping on the beach. They had no housing, but they had an iPhone, the most expensive smart phone in the market.?

While that example may seem extreme, it illustrates the growing appeal and need for a smart phone for people throughout the world. Howe notes that it will be interesting to see what products or necessities some people will sacrifice to be connected to the world through a smart phone, as it will likely differ from one society to another.

?Smart phones are increasingly things that people want, and they?re willing to give up other things for them,? he says. ?This is going to change culture in pretty significant ways.?

Affiliate marketing added benefits each the web based company and the affiliate. With affiliate promoting, an via the internet small business will have an improve in website traffic on the web site, and, consequently, produce a great deal more sales. With affiliate marketing and advertising, an affiliate can earn revenue just by referring guests to the web page of the online home business. Every single client take a look at is converted to an agreed amount for the affiliate. But, does this come about normally?

Some affiliates who have been involved in affiliate promoting may possibly answer that the conversion of visits to income does not occur regularly sufficient. Are there also countless affiliates already? Of course not. The cyberspace has a limitless provide of clientele and their numberss are developing each second. There could in no way be also quite a few affiliates. But there are approaches in which a single affiliate can earn far more capital than his counterparts.

These methods have been proven time and again by affiliate marketing authorities. Hence, an affiliate will need to strategy to carry out these recommendations so that his revenue will greatly increase.

1. Study Search Engine Optimization

The target clients of affiliates are these that get inside cyberspace and surf the World wide web to acquire facts and goods. These target consumers can readily do the surfing and the looking by applying Search Engines. Therefore, the affiliate?s site need to unearth its way in the first benefits web page of a Search Engine.

The job now of the affiliate is to discover out how to have his web page listed and ranked higher by Search Engines and Directories. This is why the affiliate should study search engine optimization.

iBuyPower Valkyrie CZ-17


The iBuypower Valkyrie CZ-17 ($1,399 list) is a large, purpose-built performance laptop, and there's no doubt that you're carrying a lot of performance hardware with you. It's a true desktop replacement, with upgradable components, space for multiple hard drives, and a huge 1080p screen. If you need a big performance system for not a lot of money, relatively, then consider the Valkyrie a good choice for under $1,500.

Design and Features
The Valkyrie is an unsubtle, unapologetic gaming laptop. As such it is a huge mass of black plastic with lots of lighted accents including the keyboard, lid, speakers, and the system's trackpad. The system measures about 2.5-by-17-by-12 inches (HWD) and tips the scales at 8.56 pounds. This is a beefy system that will strain your back or the airline tray if you deign to travel with the system. This is larger in every dimension compared with the Editors' Choice for entry-level gaming laptops, the MSI GX60 1AC-021US ($1,299 list), but in the grand scheme of things they're both par for the course when it comes to moderately priced enthusiast gaming rigs.

The Valkyrie comes with a full-size backlit keyboard with numeric keypad. Like the MSI GX60, the Valkyrie has a few quirks: The Start button is to the right of the space bar instead of the left, and the placement of the numeric keypad pushes the arrow keys to the left in relation to the return key. Both will make you retrain your muscle memory if you're used to standard desktop keyboards. The Valkyrie has a much shallower trackpad than the MSI GX60, which will make the trackpad easier to use during day-to-day use and with Windows 8 commands. However, the trackpad isn't one of the better ones out there, registering mouse movements while we typed on the keyboard. Most gamers would be more comfortable using a USB 2.0 mouse for gaming sessions and day to day.

The Valkyrie has a decent selection of I/O ports, including two USB 2.0 ports on the right for accessories like mice and three USB 3.0 ports on the left for hard drives. The other ports include a SD card reader, multiple audio jacks, a Kensington lock port, Ethernet (with Killer brand network card), VGA, eSATA, and a HDMI port. It lacks newer ports like Thunderbolt and mini-DisplayPort, but the system has a good collection of current and legacy ports.

One neat feature is that the WASD keys and arrow keys are outlined in red, since these are the most important keys for many FPS, RPG, and MMO games. It would have been nice if iBuypower had incorporated a way to darken the other keys not in use or light the WASD keys in a different color, like on the Samsung Series 7 Gamer ($1,899). In any case, the system is easy to use in a darkened room, especially if you have a flashy mouse. There's a row of soft-touch keys above the keyboard, which let you eject the DVD drive, turn off the display, put the system into airline mode, toggle the keyboard lighting, open the media player, or activate the cooler boost. Cooler boost will help in a hot room, but the switch seemed to simply make the system louder in our air-conditioned lab.

In addition to the Gigabit Ethernet, the Valkyrie comes with 802.11 b/g/n Wi-Fi, but no 5GHz bands. The system comes with a DVD burner, though we wish our review unit had the optional Blu-ray drive for 1080p movies. Movies and games displayed smoothly on the system's 17.3-inch 1,920 by 1,080 display. While they're in the same price range, the Valkyrie CZ-17 and MSI GX60 give you a lot more screen real estate than the ultraportable Editors' Choice Maingear Pulse 11 ($1,349) and it's Clevo-chassis brothers, the AVADirect Clevo W110ER ($1129) and former EC Eurocom Monster 1.0 ($1,605). The trio of systems that are built on the Clevo W110ER chassis are limited to a 1,366-by-768 resolution on their 11-inch screens. The Clevo W110ER siblings and the tablet-based Razer Edge Pro ($1,450) are made more for portability, and the MSI GX60 and this Valkyrie CZ-17 are built around their huge screens. At least all of these choices, including the Valkyrie, come with removable or supplemental batteries, bucking the trend to make everything sealed and non-serviceable.

Speaking of serviceability, the Valkyrie CZ-17 comes with a service manual to guide users through CPU, memory, and hard drive upgrades. The system comes with three free slots for up to 32GB of memory total, and you won't have to remove the included 8GB in our test unit. There's even space for a second internal hard drive, which means you can upgrade to a SSD later. Note that if you do open your Valkyrie CZ-17 for service, you will void the one-year warranty.

Performance
iBuyPower Valkyrie CZ-17 The Valkyrie CZ-17 comes with an Intel Core i7-3630QM processor, 8GB of memory, 4GB Nvidia GeForce GTX 675MX discrete graphics, and a 7,200rpm 750GB SATA hard drive. All of these components work together to give the system excellent marks on the multimedia tests like Handbrake, CineBench, and Photoshop CS6. In fact, the system runs through the Handbrake and Photoshop tests as fast as many high-end multimedia desktop PCs.

However, the biggest disappointment with the system was its 3D gaming scores. While it's smoothly playable at the medium quality settings at 1,366-by-768 resolution, the games we tested (Aliens vs. Predator and Heaven) were just under the 30fps (frames per second) barrier, denoting that you will occasionally see some stuttered frames as we did during testing. The EC for entry-level gaming laptops, the MSI GX60 1AC-02US was 10 frames per second faster on both tests. Those extra 10 FPS yield smoother gameplay. Unfortunately for the iBuypower, that means that the MSI GX60 is a much better gaming platform, even though the Valkyrie topped the MSI GX60 by a good measure on the multimedia and day-to-day performance tests. The MSI simply has a better AMD Radeon HD 7970M GPU, while the iBuypower has a much faster Intel Core i7 CPU. Those are the tradeoffs you need to consider at this price point.

The Valkyrie system has a turbo function key combination (FN-F1), which ran an on screen animation to tell us that it was active. The manual describes it as Over-Clocking. However, when we tried running Aliens vs. Predator again with both the turbo and cooler boost functions active the score on the high quality test only went up by 0.2 FPS. This is a negligible improvement, and as such we'd describe these settings as all show, no go.

The Valkyrie's quad-core processor, large screen, and other battery-draining features kept the system to a scant 2 hours 19 minutes on our battery rundown test. That's not even enough to finish the first of the Lord of the Rings movie, the Fellowship of the Ring. Basically, this means that you really need to keep close to a power outlet when you use the Valkyrie.

The iBuypower Valkyrie CZ-17 is a great multimedia laptop with some gaming prowess. The big problem is that for $100 less, the EC-winning MSI GX60 has much better gaming performance. And, if I'm not mistaken, that's why you would buy a humungous gaming rig over a thin and light ultrabook with excellent multimedia performance. Thus the GX60 holds on to its Editors' Choice award, but consider the Valkyrie if you're going to spend a lot of time in between gaming sessions editing photos, videos, and the like.

Algeria president sent to Paris after mini-stroke

ALGIERS, Algeria (AP) ? Algeria's state news agency says the president has been transferred to Paris for medical treatment following a mini-stroke.

The report published early Sunday said that though the brief blockage of a blood vessel known as transient ischemic attack had "no complications," according to authorities, Abdelaziz Bouteflika's doctors had recommended additional tests.

French and Algerian media say the 76-year-old president had been checked into Val de Grace hospital, where he was treated in 2005 for a bleeding ulcer.

There have long been concerns about Bouteflika's health, especially since the president rarely appears in public.

Bouteflika, president since 1999, is credited with seeing Algeria through the end of a bloody civil war against Islamists and ruling in an uneasy partnership with the powerful military.

3 Taliban bombs target Pakistani politicians

PARACHINAR, Pakistan (AP) ? Taliban bombs targeting politicians in northwestern Pakistan on Sunday killed 11 people, the latest in a series of attacks meant to disrupt next month's parliamentary election, police said.

The wave of political violence has killed at least 60 people in recent weeks, and many of the attacks have been directed at candidates from secular parties opposed to the Taliban. That has raised concern the violence could benefit hard-line Islamic candidates and others who are more sympathetic to the Taliban because they are able to campaign more freely without fear of being of being attacked.

Pakistani Taliban spokesman Ahsanullah Ahsan claimed responsibility for the three attacks, plus two others against secular parties in the southern port city of Karachi on Saturday that killed four people and wounded over 40.

"We are against all politicians who are going to become part of any secular, democratic government," Ahsan told The Associated Press by telephone from an undisclosed location.

The first bomb on Sunday ripped through the campaign office of Syed Noor Akbar on the outskirts of Kohat city, killing six people and wounding 10, police officer Mujtaba Hussain said.

A second bomb targeted the office of another candidate, Nasir Khan Afridi, in the suburbs of Peshawar city. That attack killed three people and wounded 12, police officer Saifur Rehman said.

The politicians were not in their offices at the time of the blasts. They are both running as independent candidates for parliament to represent constituencies in Pakistan's rugged tribal region along the Afghan border, the main sanctuary for Taliban and al-Qaida militants in the country.

Many politicians running in the May 11 election from the tribal region have their offices located elsewhere and find it hard to campaign in their constituencies because of the danger. The two who were attacked Sunday are considered to hold relatively progressive views compared to the deeply conservative Islamic beliefs of many in the tribal region.

The third attack occurred in the town of Swabi, where a bomb went off during a small rally held by the Awami National Party, which has been repeatedly targeted by the Taliban. The blast killed two people and wounded five, said police officer Farooq Khan. The two candidates targeted in the attack, Ameer Rehman and Haji Rehman, were not hurt.

The Pakistani Taliban have been waging a bloody insurgency against the government for years that has killed thousands of civilians and security personnel. The group's goal is to oust Pakistan's democratic government and implement a system based on Islamic law.

In mid-March, the Taliban threatened attacks against three secular parties that have earned the militants' ire by supporting military operations against them in the northwest: the Awami National Party, the Muttahida Quami Movement and the Pakistan People's Party. The Taliban have carried out at least 20 attacks against politicians and campaign workers since then, mostly from these three parties.

The violence has forced the parties to close dozens of campaign offices and has prevented them from holding large political rallies that are normally the hallmark of Pakistani elections. Many of the candidates have had to find ways to campaign from a distance, relying more on social media, advertisements and even short documentaries to rally support.

That has put these candidates at a disadvantage, and many have complained the militant violence amounts to vote rigging.

Candidates from Islamic parties and others who have advocated negotiating peace with the militants rather than fighting them have been able to campaign with much less fear of being attacked.

Former Prime Minister Nawaz Sharif, head of the Pakistan Muslim League-N party, held a rally with several thousand people in the northern town of Murree on Sunday without incident. Many analysts predict Sharif's party will come out on top in the parliamentary election.

The Taliban issued a statement earlier this year requesting that Sharif and the heads of the country's two largest Islamic parties mediate peace negotiations. Sharif declined but said he was a supporter of the talks.

The parties that have been targeted by the Taliban also support peace negotiations with the militants, but only if they lay down their weapons and accept the constitution first ? conditions the militant group has rejected.

Officials: Bomb suspect silent after read rights

FILE - This combination of undated file photos shows Tamerlan Tsarnaev, 26, left, and Dzhokhar Tsarnaev, 19. The FBI says the two brothers are the suspects in the Boston Marathon bombing, and are also responsible for killing an MIT police officer, critically injuring a transit officer in a firefight and throwing explosive devices at police during a getaway attempt in a long night of violence that left Tamerlan dead and Dzhokhar captured, late Friday, April 19, 2013. The ethnic Chechen brothers lived in Dagestan, which borders the Chechnya region in southern Russia. They lived near Boston and had been in the U.S. for about a decade, one of their uncles reported said. Since Monday, Boston has experienced five days of fear, beginning with the marathon bombing attack, an intense manhunt and much uncertainty ending in the death of one suspect and the capture of the other.

BOSTON (AP) ? Sixteen hours after investigators began interrogating him, the surviving suspect in the Boston Marathon bombings went silent: He'd just been read his constitutional rights.

Dzhokhar Tsarnaev immediately stopped talking after a magistrate judge and a representative from the U.S. Attorney's office entered his hospital room and gave him his Miranda warning, according to a U.S. law enforcement source and four officials of both political parties briefed on the interrogation. They insisted on anonymity because the briefing was private.

Before being advised of his rights, the 19-year-old suspect told authorities that his older brother, Tamerlan Tsarnaev, 26, only recently had recruited him to be part of the attack that detonated pressure-cooker bombs at the marathon finish line, two U.S. officials said.

The CIA, however, had named Tamerlan to a terrorist database 18 months ago, said officials close to the investigation who spoke to The Associated Press on condition of anonymity because they were not authorized to discuss the case with reporters.

The new disclosure that Tamerlan Tsarnaev was included within a huge, classified database of known and suspected terrorists before the attacks was expected to drive congressional inquiries in coming weeks about whether the Obama administration adequately investigated tips from Russia that Tsarnaev had posed a security threat.

Shortly after the bombings, U.S. officials said the intelligence community had no information about threats to the marathon before the April 15 explosions that killed three people and injured more than 260.

Tsarnaev died Friday in a police shootout hours before Dzhokhar was discovered hiding in a boat in a suburban back yard.

Boston police Commissioner Ed Davis had said earlier that shots were fired from inside the boat, but two U.S. officials told the AP that the suspect was unarmed when captured by police, raising questions about how he was injured. The homeowner who called police initially said he saw a good amount of blood in the boat.

Washington is piecing together what happened and whether there were any unconnected dots buried in U.S. government files that, if connected, could have prevented the bombings.

Lawmakers who were briefed by the FBI said they have more questions than answers about the investigation of Tamerlan Tsarnaev. House Judiciary Chairman Bob Goodlatte, R-Va., said lawmakers intend to pursue whether there was a breakdown in information-sharing, though Rep. Adam Schiff, a California Democrat who sits on the House Intelligence Committee, said he "hasn't seen any red flags thus far."

U.S. officials were expected to brief the Senate on the investigation Thursday.

The suspects' father said Thursday that he is leaving Russia for the United States in the next day or two, but their mother said she was still thinking it over.

Anzor Tsarnaev has expressed a desire to go to the U.S. to find out what happened with his sons, defend his hospitalized 19-year-old son Dzhokhar and if possible bring his older son's body back to Russia for burial.

Their mother, Zubeidat Tsarnaeva, who was charged with shoplifting in the U.S. last summer, said she has been assured by lawyers that she would not be arrested, but was still deciding whether to go.

It is unclear whether the issue of their younger son's constitutional rights will matter since the FBI say he confessed to a witness. U.S. officials also said Wednesday that physical evidence, including a 9 mm handgun and pieces of a remote-control device commonly used in toys, was recovered from the bombing scene.

But the debate over whether suspected terrorists should be read their Miranda rights has become a major sticking point in the debate over how best to fight terrorism. Many Republicans, in particular, believe Miranda warnings are designed to build court cases, and only hinder intelligence gathering.

Christina DiIorio Sterling, a spokeswoman for U.S. Attorney Carmen Ortiz, said in an email late Wednesday, "This remains an ongoing investigation and we don't have any further comment."

Investigators have said the brothers appeared to have been radicalized through jihadist materials on the Internet and have found no evidence tying them to a terrorist group.

U.S. investigators traveled to the predominantly Muslim province of Dagestan in Russia and were in contact with the brothers' parents, hoping to gain more information.

They are looking into whether Tamerlan, who spent six months in Russia's turbulent Caucasus region in 2012, was influenced by the religious extremists who have waged an insurgency against Russian forces in the area for years. The brothers have roots in Dagestan and neighboring Chechnya but had lived in the U.S. for about a decade.

Dzhokhar told the FBI that they were angry about the U.S. wars in Afghanistan and Iraq and the killing of Muslims there, officials said.

Dzhokhar's public defender had no comment on the matter Wednesday. His father has called him a "true angel," and an aunt has insisted he's not guilty.

Investigators have found pieces of remote-control equipment among the debris and were analyzing them, officials said. One official described the detonator as "close-controlled," meaning it had to be triggered within several blocks of the bombs.

That evidence could be key to the court case. And an FBI affidavit said one of the brothers told a carjacking victim during their getaway attempt, "Did you hear about the Boston explosion? I did that."

Officials also recovered a 9 mm handgun believed to have been used by Tamerlan from the site of an April 18 gunbattle that injured a Massachusetts Bay Transportation Authority officer, two U.S. officials said.

In other developments:

? Vice President Joe Biden condemned the bombing suspects as "two twisted, perverted, cowardly, knockoff jihadis" while speaking at a memorial service Wednesday for Sean Collier, a campus police officer at the Massachusetts Institute of Technology who was ambushed in his cruiser three days after the bombing. More than 4,000 mourners paid tribute to the officer.

? The Office of Health and Human Services in Massachusetts confirmed a Boston Herald report Wednesday that Tamerlan, his wife and toddler daughter had received welfare benefits up until last year, when he became ineligible based on family income. The state also says Tamerlan and his brother received welfare benefits as children through their parents while the family lived in Massachusetts.

? The area around the marathon finish line was reopened to the public.

How one man survived a deadly avalanche

DENVER (AP) ? The sole survivor of an avalanche that killed five other men on the Continental Divide west of Denver was able to clear snow from his face with his unburied lower left arm so he could breathe, but he remained stuck for four hours until rescuers arrived, the Colorado Avalanche Information Center said Wednesday.

In its final report on the weekend accident, the center said the state's deadliest slide since 1962 was large enough to bury or destroy a car. Of the men who died in the 800-foot-wide, 600-foot-long avalanche Saturday morning, one was buried under 10 to 12 feet of snow.

The avalanche was tragic but avoidable, the center said.

The center's final report offered new details on the avalanche that occurred as snowboarders and skiers converged near Loveland Pass for the Rocky Mountain High Backcountry Gathering. The event was promoted by a Colorado snowboarding magazine as a day for backcountry riding but also avalanche gear and safety demonstrations.

The four snowboarders and a skier who died were all from Colorado. The Clear Creek County sheriff's office identified them as Christopher Peters, 32, of Lakewood; Joseph Timlin, 32, of Gypsum; Ryan Novack, 33, of Boulder; Ian Lamphere, 36, of Crested Butte; and Rick Gaukel, 33, of Estes Park.

Friends identified the survivor as Jerome Boulay of Crested Butte, who has declined requests for interviews.

All had proper avalanche equipment. At least two had avalanche airbags, and some had Avalung breathing devices but apparently were unable to use them, the report said.

"This was a really tragic accident. There's no denying that," said Ethan Greene, the center's director. "Nobody's immune from getting caught in avalanches. It doesn't matter how long you've been doing this, how athletic you are. ... Everybody can get killed. It's an equal-opportunity hazard."

The center has said the avalanche was a deep persistent slab avalanche, which occurs when a thick layer of hard snow breaks loose from a weak, deep layer of snowpack underneath. Colorado Avalanche Information Center forecasters had alerted people about the potential for such avalanches Saturday, warning of likely trigger points.

"If you find the wrong spot, the resulting avalanche will be very large, destructive, and dangerous," the forecast said.

On Saturday, Boulay and the other five men had left the parking lot of Loveland Ski Area, which wasn't affiliated with the backcountry gathering, for a one-hour tour.

They read the center's avalanche bulletin together, were aware of the deep persistent slab problem, and aimed to avoid threatening north-facing slopes as they planned to climb a few hundred vertical feet onto northwest-facing slopes, the report said.

But to get to that safer spot, they had to cross a dangerous area, Greene said. They decided to reduce the risk by leaving 50 feet between each person as they trekked. That turned out not to be enough for the large avalanche they triggered.

The group was heading for a stand of trees when they felt a large collapse and heard a "whumpf," the report said. In the seconds it took for the crack in the snow to move uphill and release the deep slab, the group ran toward the trees. Everyone but Boulay was completely buried as the group was swept into the Sheep Creek gully.

Boulay was buried except for his lower left arm, which he used to clear snow from his face. He tried to free his other arm and screamed for help.

There was no one around to hear him, the report said.

"It covered everybody. There was nobody left to call 911, nobody left to look for the buried, to help the one person who wasn't buried but couldn't get out," Greene said.

It took a while for anyone to realize the group was trapped.

Two Colorado Avalanche Information Center highway avalanche forecasters spotted the slide around 12:15 p.m. from Interstate 70. When they got to the scene about 30 minutes later, their avalanche beacons detected no signals. Even with binoculars, they couldn't see tracks heading into the slide area, the report said.

After forecasters drove back to the ski area to ask others at the backcountry gathering whether anyone might be trapped, several people rushed to the scene.

The center urges even expert backcountry enthusiasts to know the conditions, have rescue equipment and get educated on avalanches.

"We owe it to these guys to learn from a really horrible accident they were involved in," Greene said. "The only thing worse than all these guys getting killed is not to have us learn anything from it."

What planets are made of: Findings establish counterintuitive potential planet-forming materials

Apr. 24, 2013 ? A team of researchers led by Artem R. Oganov, a professor of theoretical crystallography in the Department of Geosciences, has made a startling prediction that challenges existing chemical models and current understanding of planetary interiors -- magnesium oxide, a major material in the formation of planets, can exist in several different compositions. The team's findings, "Novel stable compounds in the Mg-O system under high pressure," are published in the online edition of Physical Chemistry Chemical Physics. The existence of these compounds -- which are radically different from traditionally known or expected materials -- could have important implications.

"For decades it was believed that MgO is the only thermodynamically stable magnesium oxide, and it was widely believed to be one of the main materials of the interiors of the Earth and other planets," said Qiang Zhu, the lead author of this paper and a postdoctoral student in the Oganov laboratory.

"We have predicted that two new compounds, MgO2 and Mg3O2, become stable at pressures above one and five million atmospheres, respectively. This not only overturns standard chemical intuition but also implies that planets may be made of totally unexpected materials. We have predicted conditions (pressure, temperature, oxygen fugacity) necessary for stability of these new materials, and some planets, though probably not the Earth, may offer such conditions," added Oganov.

In addition to their general chemical interest, MgO2 and Mg3O2 might be important planet-forming minerals in deep interiors of some planets. Planets with these compounds would most likely be the size of Earth or larger.

The team explained how its paper predicted the structures in detail by analyzing the electronic structure and chemical bonding for these compounds. For example, Mg3O2 is forbidden within "textbook chemistry," where the Mg ions can only have charges "+2," O ions are "-2, and the only allowed compound is MgO. In the "oxygen-deficient" semiconductor Mg3O2, there are strong electronic concentrations in the "empty space" of the structure that play the role of negatively charged ions and stabilize this material. Curiously, magnesium becomes a d-element (i.e. a transition metal) under pressure, and this almost alchemical transformation is responsible for the existence of the "forbidden" compound Mg3O2.

The findings were made using unique methods of structure prediction, developed in the Oganov laboratory. "These methods have led to the discovery of many new phenomena and are used by a number of companies for systematically discovering novel materials on the computer -- a much cheaper route, compared to traditional experimental methods," said Zhu.

"It is known that MgO makes up about 10 percent of the volume of our planet, and on other planets this fraction can be larger. The road is now open for a systematic discovery of new unexpected planet-forming materials," concluded Oganov.

This work is funded by the National Science Foundation and DARPA.

Forced exercise may still protect against anxiety and stress

Apr. 25, 2013 ? Being forced to exercise may still help reduce anxiety and depression just as exercising voluntarily does, according to a new study by researchers at the University of Colorado Boulder.

Past studies have shown that people who exercise are more protected against stress-related disorders. And scientists know that the perception of control can benefit a person's mental health. But it has been an open question whether a person who feels forced to exercise, eliminating the perception of control, would still reap the anxiety-fighting benefits of the exercise.

People who may feel forced to exercise could include high school, college and professional athletes, members of the military or those who have been prescribed an exercise regimen by their doctors, said Benjamin Greenwood, an assistant research professor in CU-Boulder's Department of Integrative Physiology.

"If exercise is forced, will it still produce mental health benefits?" Greenwood asked. "It's obvious that forced exercise will still produce peripheral physiological benefits. But will it produce benefits to anxiety and depression?"

To seek an answer to the question Greenwood and his colleagues, including Monika Fleshner, a professor in the same department, designed a lab experiment using rats. During a six-week period, some rats remained sedentary, while others exercised by running on a wheel.

The rats that exercised were divided into two groups that ran a roughly equal amount of time. One group ran whenever it chose to, while the other group ran on mechanized wheels that rotated according to a predetermined schedule. For the study, the motorized wheels turned on at speeds and for periods of time that mimicked the average pattern of exercise chosen by the rats that voluntarily exercised.

After six weeks, the rats were exposed to a laboratory stressor before testing their anxiety levels the following day. The anxiety was quantified by measuring how long the rats froze, a phenomenon similar to a deer in the headlights, when they were put in an environment they had been conditioned to fear. The longer the freezing time, the greater the residual anxiety from being stressed the previous day. For comparison, some rats were also tested for anxiety without being stressed the day before.

"Regardless of whether the rats chose to run or were forced to run they were protected against stress and anxiety," said Greenwood, lead author of the study appearing in the European Journal of Neuroscience in February. The sedentary rats froze for longer periods of time than any of the active rats.

"The implications are that humans who perceive exercise as being forced -- perhaps including those who feel like they have to exercise for health reasons -- are maybe still going to get the benefits in terms of reducing anxiety and depression," he said.

Other CU-Boulder authors include Katie Spence, Danielle Crevling, Peter Clark and Wendy Craig. All the authors are members of Monika Fleshner's Stress Physiology Laboratory in the Department of Integrative Physiology.

The research was funded by the National Institutes of Mental Health and the Defense Advanced Research Projects Agency.

Microsoft announces Xbox event for May 21st

What many suspected was coming has indeed happened: Microsoft just confirmed an upcoming Xbox event on May 21st, which we expect to be focused on the company's next-gen Xbox console (informally codenamed Durango). The company isn't diving into specifics at this stage, but the event is taking place on its own Xbox campus and should offer a "real taste of the future," according to Xbox Live programming director Larry Hryb. Don't worry too much that Microsoft will completely upstage E3, which happens just a few weeks later -- Hryb also promises that his firm "continue the conversation" at the show, focusing its attention on its game lineup. Players will have a chance to stream the event through both Microsoft's services (including Xbox Live) and Spike TV, but you can be sure we'll be on the ground to share the news first-hand.

Study finds that residential lawns efflux more carbon dioxide than corn fields

Wednesday, April 24, 2013

More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought.

These findings provide a better understanding of the changes that occur when agricultural lands undergo development and urbanization to support growing urban populations.

David Bowne, assistant professor of biology, led the study to look at the amount of carbon dioxide being released from residential lawns versus corn fields in Lancaster County, Pennsylvania. His co-author, Erin Johnson, was an undergraduate at the time of the study and did the work as part of her senior honors thesis. Their findings were published online today in Soil Science Society of America Journal.

For Bowne, the study allowed him to look beyond the obvious impact of losing agricultural fields to development ? the loss of food that was once produced on the land.

"That is a legitimate concern, but I wanted to look more at how this change could potentially impact the carbon cycle with the understanding that the carbon cycle has implications for global climate change," explains Bowne.

To begin to understand how the carbon cycle was changing, Bowne and Johnson measured carbon dioxide efflux, soil temperature, and soil moisture under the two different land uses. They found that both carbon dioxide efflux and soil temperature were higher in residential lawns than in corn fields. Additionally, temperature had the most influence on the levels of carbon dioxide efflux, followed by the type of land use.

Higher temperatures leading to increased carbon dioxide efflux was not a surprise for Bowne and Johnson as this relationship has been documented before. "As you increase temperature," Bowne explains, "you increase biological activity ? be it microbial, plant, fungal, or animal." That increased activity, then, leads to more respiration and higher levels of carbon dioxide leaving the soils.

What was unexpected, however, was that the higher temperatures found in residential lawns suggested urban heat islands working at small scales. Urban heat islands are well documented phenomena in which development leads to large areas of dark-colored surfaces such as roofs, buildings, and parking lots. The dark color means more heat is absorbed leading to an increase in temperature in the neighboring areas. Urban areas, then, are warmer than the surrounding countryside.

The interesting part of Bowne's study is that the urban heat islands in the areas he was looking seem to operate on much smaller scales than he previously thought. While heat islands are usually studied on large scales ? such as comparing a large city and its surrounding rural areas ? fewer studies have been done to work out how development may affect temperatures on small scales.

"Within a developed area, within a city or town, you could have local increases in soil temperature because of the amount of development within a really small area," says Bowne.

His research suggests that temperatures may vary even across short distances due to the influence of development. One source cited in his paper says that development within even 175 meters of a location can cause an increase in temperature. Bowne is planning further experiments to test soil temperatures over a range of development setups and sizes.

The other factor that Bowne will test in the future is the sequestration of carbon. Along with the carbon dioxide efflux data in the current study, information about carbon sequestration would give a bigger picture of carbon cycling. That picture could then help researchers determine how various land uses as well as management practices such as no-till agriculture or leaving grass clippings on lawns can change the carbon cycling.

"If we go from one land use to another land use, how does that impact carbon cycling which in turn can affect climate change? Our current study touches on one component of that cycle, and more research is needed to address this huge topic," says Bowne.

Samsung Galaxy S 4 (T-Mobile)


Samsung has something for everyone in the Android-powered Galaxy S 4 ($149.99). It's this year's no-brainer: the phone to get if you don't want to worry about which phone to get. No matter what you want to do, the Galaxy S 4 can get it done. That makes it our Editors' Choice for full-touch smartphones on T-Mobile.

Physical Features and Phone Calls
The Galaxy S 4 looks like a refined Galaxy S III at 5.4 by 2.75 by .31 inches (HWD) and 4.6 ounces. It's still plastic, in white or black, with chrome trim, and a subtly patterned, smooth back. The edges are squarer, forgoing the 'pebble in your hand' metaphor that ruled the S3. It doesn't taper. But it's almost exactly the same size as the S3, with the new phone's larger screen made possible by a smaller bezel.

loading...

?

On the front, a 1,920-by-1,080, 5-inch Super AMOLED HD display boasts a spectacular viewing angle and shimmering colors. The physical Home button, below it, joins the traditional Android Menu and Back buttons. I like this setup a lot more than the perplexing two-button approach on the HTC One.

The Galaxy S 4's back is removable, giving you access to the battery and microSD card slot. You can also replace the back with an optional flip cover that sports a window near the top; when the cover is flipped closed, you see the time and alerts through the window. I had trouble getting the flip cover to stay closed when sitting on a desk, though. The front just wouldn't lie flat.

An excellent voice phone, the S 4 is really, really good, and that's not just because of T-Mobile's new HD Voice. In my tests, call quality was unusually sharp and clear, and the earpiece and speakerphone both got quite loud. Transmissions were sharp, too, with excellent noise cancellation that doesn't damage the quality of the voice. Transmissions from the speakerphone were a touch tinny, but very clear. Just like on the Galaxy S III, you can personalize the call sound profile to your own sense of hearing, which is one of the phone's best hidden features. The S 4 also supports T-Mobile's excellent Wi-Fi calling system.

Basic Performance and Networking
The Galaxy S 4 is the fastest smartphone we've benchmarked so far, thanks to its 1.9GHz quad-core Qualcomm Snapdragon 600 processor. Yes, some other international S 4 models will get the Samsung Exynos octo-core, but that processor isn't necessarily any faster or better, it just takes a different approach to a low-power mode.?

Along with the processor, Samsung gets props for running Android 4.2.2, the latest version of Google's mobile OS. Some of the newest features aren't available here, though: Multi-user mode is for tablets, and Samsung's custom camera app omits Google's Photo Spheres.

The 1.9GHz Snapdragon torched the processor-dependent Antutu benchmark, but it also did unusually well on Basemark OS, which launches real applications, and on the GLBenchmark graphics benchmark. Even pushing all the pixels on a 1080p screen, this is the fastest Android phone available. I topped off performance testing with the hideously heavy Need for Speed: Most Wanted game, which ran like butter on the S 4.

Spectacular speed results carried over to network testing, too. The Galaxy S 4 is an LTE phone, although you can switch it off if you aren't in one of T-Mobile's few LTE cities. You don't lose much, either. On T-Mobile's HSPA+ network in midtown Manhattan I got speed up to 14Mbps down and 2.3Mbps up using Ookla's Speedtest.net application. That's solid 4G by anyone's measure.

The S 4 also supports GPS, Bluetooth 4.0, Wi-Fi 802.11 a/b/g/n/ac, and NFC. I connected a Plantronics Voyager Legend Bluetooth headset ?and media playback and voice dialing went off without a hitch.

Battery life isn't extraordinary, but it's good. I got 10 hours, 50 minutes of talk time, and?4 hours, 48 minutes streaming constant video over HSPA+ with the screen set to maximum brightness. As we've seen with these 1080p phones, that high-res screen really takes a toll.?

Five people shot to death in small Illinois town

MANCHESTER, Ill. (AP) ? Authorities are investigating the slayings of five people whose bodies were found in a house in the tiny Scott County community of Manchester. A suspect is in custody.

Illinois State Police spokeswoman Monique Bond says the victims were found early Wednesday morning in the southwestern Illinois community, 50 miles west of Springfield. She didn't have any details on the deaths or the circumstances surrounding the capture of the suspect.

A school superintendent in the area says he was informed by sheriffs early Wednesday morning that the victims had been shot to death. Les Stevens of the North Greene School District says he canceled classes because authorities warned him at the time that the suspect was at large. The district has since been informed that the man was captured.
