South Africa says Mandela's condition has improved

LAHORE, March 31 (Reuters) - Pakistan have dropped senior batsman Younus Khan from the list of 30 probable players announced for this year's ICC Champions Trophy on Sunday. Younus, 35, was the only surprise omission and the decision probably signals the end of his one-day international career which has spanned 253 matches. The former captain struggled in the recent one-day series in South Africa and has been out of form in this format of the game since last year. ...

Simple Tips For The Do It Yourselfer Home Improvement | How To ...

TIP! Add value to your house by refinishing your wood flooring. Although it takes a lot of work to re-finish floors properly, the job isn?t really that complex.

Would you like to feel confident about home improvement projects? Perhaps you just want to save money, or maybe you don?t want strangers in your home. Whatever your motivation for taking matters into your own hands, here are some home improvement tips that will make your home improvements easier.

TIP! Inspect the foundation of your home for damage as part of your yearly winterizing routine. Insects and rodents will hide in small warm places which is why you need to seal any entry point to keep pest away.

Try reusing materials when you?re doing a home improvement project so that money can be saved as well as the environment. Why not give your cabinets a fresh look by painting them? You can give them a facelift by replacing the handles and knobs on them. Additionally, you can paint your ceramic tile for a new look at a fraction of the cost.

TIP! Don?t forget about safety. Any project involves risk; therefore, you should thoroughly read over instructions on any power tools you plan on using.

Use a sponge when installing drywall. Rather than sanding drywall seams, you should use a sponge. A wet sponge can be as effective as careful sanding when it comes to smoothing out seams. The advantage is that sponging doesn?t kick up all of the dust that sanding does.

TIP! Give an old luggage rack a chance to shine by turning it into a low cost, but effective side table in your living room. Just take glass out of an old picture frame and set it on top, adhering it with permanent glue.

Try planting a tree as an inexpensive way to improve the curb appeal of your home. A well landscaped yard can significantly boost your home?s value. It will also, eventually, shade your home. In addition, a tree placed in the right location can lower cooling costs by 40 percent.

TIP! Add a new sink to an old kitchen. This will create a modernized look to your kitchen.

Keep any small jars (like baby food jars) for use in organizing your space. You can screw or superglue the jar lids under the wall shelf. You can use these jars to store different items like nails and screws. Twist the jars into the lids back under the shelf. This helps take full advantage of a wall shelf and small jars you didn?t think you would ever need.

TIP! Be careful when demolishing areas to be improved in your home. Many people have the urge to go as fast as they can to speed things up.

The information you just read will help you as you embark on your home improvement journey. You can achieve your dream look without hiring other people to do the work. Follow the advice in this article and you?ll be well on your way to realizing your dream.

N. Korea claims a 'state of war' with S. Korea

By Jack Kim

SEOUL (Reuters) - North Korea said on Saturday it was entering a "state of war" with South Korea in a continuing escalation of angry rhetoric directed at Seoul and Washington, but the South brushed off the statement as little more than tough talk.

The two Koreas have been technically in a state of war for six decades under an armistice that ended their 1950-53 conflict. Despite its threats few people see any indication Pyongyang will risk a near-certain defeat by re-starting full-scale war.

"From this time on, the North-South relations will be entering the state of war and all issues raised between the North and the South will be handled accordingly," a statement carried by the North's official KCNA news agency said.

KCNA said the statement was issued jointly by the North's government, ruling party and other organizations.

There was no sign of unusual activity in the North's military or anything to suggest an imminent aggression, a South Korean defense ministry official said.

North Korea has been threatening to attack the South and U.S. military bases almost on a daily basis since the beginning of March, when U.S. and South Korean militaries started routine drills.

But the North has kept a joint industrial zone with the South running. The Kaesong zone is a source of hard currency for the impoverished state and hundreds of South Korean workers and vehicles enter daily after crossing the heavily armed border between the rivals.

North Korean leader Kim Jong-un on Friday signed off on an order putting its missile units on standby to attack U.S. military bases in the South and the Pacific, after the United States flew two nuclear-capable stealth bombers over the Korean peninsula in a rare show of force.

U.S. officials said the B-2 bombers were on a diplomatic sortie aimed at reassuring allies South Korea and Japan and were also aimed at trying to nudge Pyongyang back to dialogue, although there was no guarantee Kim would get the message as intended.

The South Korean government brushed off the North's latest statement on Saturday, saying there was nothing fresh in it to cause greater alarm. South Koreans went about with daily lives as they have done through March under the North's constant threat of attack.

The Unification Ministry, which handles political ties with the North, said the Kaesong industrial park was operating as normal with workers and vehicles crossing the border both says.

"North Korea's statement today ? is not a new threat but is the continuation of provocative threats," a ministry statement said.

The Defence Ministry urged the North to stop issuing threats, reiterating the position that annual military drills conducted jointly with U.S. forces until the end of April were strictly defensive in nature.

The North's statement said it would respond "without mercy" to any action by the South that harmed its sovereignty, suggesting it was not about to mount a pre-emptive attack.

In 2010, North Korea bombed a South Korean island close to the maritime border that Pyongyang disputes, killing two civilians and two soldiers and prompting the South to strike back with artillery and sharply elevating tensions.

Earlier that year, a South Korean navy ship was struck by a torpedo and sank, killing 46 sailors in an incident widely blamed on the North's military although Pyongyang denies the charge.

Bible comes to life as locusts swarm Israel

Israeli Jews celebrating Passover will easily relate to their ancestors this year ? the country has been swarmed by millions of locusts, one of the 10 plagues visited on the Egyptians.

By Christa Case Bryant,?Staff writer / March 27, 2013

Locusts make their way from Egypt just before they land in Kerem Shalom near the border with Egypt, in southern Israel's Negev Desert, March 11.

Ariel Schalit/AP

Enlarge

Locusts have descended on Israel this week, just in time for Passover. As millions of Jews commemorate the story of the children of Israel?s exodus from Egypt, including the 10 plagues that afflicted Pharaoh and his people, millions of the crunchy buggers are creeping all over Israel?s southern deserts.

This is nothing like the eighth plague of biblical times, in which locusts covered ?the whole face of the earth? in a kind of collective punishment for the Egyptians whose leader refused to let his Hebrew slaves go free.

But this year is the first time since 2005 that modern-day Israel has had to combat locusts, which can swarm so thickly that drivers can?t see beyond their windshield. Potato farmers bemoaned the detrimental effect of a previous wave of the grasshopper-like insects several weeks ago. The Israeli Ministry of Agriculture, which was on ?locust alert,? has responded quickly to the latest wave with pesticides.?

But it?s not just Israel. Today the Palestinian Authority?s Ministry of Agriculture sprayed pesticides in Hebron, in the southern West Bank. And Egyptian farmers have suffered millions of dollars in damage after a swarm of about 30 million locusts hit Cairo earlier this month.

The most serious situation, however, appears to be in Sudan, where the United Nations Food & Agricultural Organization (FAO) head has warned that immature ?hoppers? are lining up along a 1,000-kilometer (621-mile) stretch of the Nile and could pose a serious threat to Nile Valley crops in May.

OK, so locusts are not your average grasshopper. But still, how can they cause such massive damage?

Consider these arresting facts: They can eat their weight in crops every day; They can fly more than 80 miles a day ? in swarms as dense as 200 million per square mile; And females can lay as many as 1,000 egg pods in roughly 10 square feet, according to a FAO fact sheet.?

To put the threat in practical terms, 1 ton of locusts (just a fraction of your average swarm) can eat about as much food as 2,500 people can in a single day, says FAO.

The Israelis have sought to reverse the food chain this Passover, however, by grilling the kosher insects for a crunchy, high-protein delicacy. And they?re not alone. Locust recipes abound.?

A Mexican version from ?Man Eating Bugs: The Art and Science of Eating Insects,? by Peter Menzel and Faith D'Aluisio calls for roasting locust torsos and sprinkling them on homemade guacamole in a taco shell. Scrap that. Sprinkle and?enjoy, the cookbook says.?

B?tayavon, as the Israelis would say.?Bon appetit.

Even graphene has weak spots

Mar. 28, 2013 ? Graphene, the single-atom-thick form of carbon, has become famous for its extraordinary strength. But less-than-perfect sheets of the material show unexpected weakness, according to researchers at Rice University in Houston and Tsinghua University in Beijing.

The kryptonite to this Superman of materials is in the form of a seven-atom ring that inevitably occurs at the junctions of grain boundaries in graphene, where the regular array of hexagonal units is interrupted. At these points, under tension, polycrystalline graphene has about half the strength of pristine samples of the material.

Calculations by the Rice team of theoretical physicist Boris Yakobson and his colleagues in China were reported this month in the American Chemical Society journal Nano Letters. They could be important to materials scientists using graphene in applications where its intrinsic strength is a key feature, like composite materials and stretchable or flexible electronics.

Graphene sheets grown in a lab, often via chemical vapor deposition, are almost neverperfect arrays of hexagons, Yakobson said. Domains of graphene that start to grow on a substrate are not necessarily lined up with each other, and when these islands merge, they look like quilts, with patterns going in every direction.

The lines in polycrystalline sheets are called grain boundaries, and the atoms at these boundaries are occasionally forced to change the way they bond by the unbreakable rules of topology. Most common of the "defects" in graphene formation studied by Yakobson's group are adjacent five- and seven-atom rings that are a little weaker than the hexagons around them.

The team calculated that the particular seven-atom rings found at junctions of three islands are the weakest points, where cracks are most likely to form. These are the end points of grain boundaries between the islands and are ongoing trouble spots, the researchers found.

"In the past, people studying what happens at the grain boundary looked at it as an infinite line," Yakobson said. "It's simpler that way, computationally and conceptually, because they could just look at a single segment and have it represent the whole."

But in the real world, he said, "these lines form a network. Graphene is usually a quilt made from many pieces. I thought we should test the junctions."

They determined through molecular dynamics simulation and "good old mathematical analysis" that in a graphene quilt, the grain boundaries act like levers that amplify the tension (through a dislocation pileup) and concentrate it at the defect either where the three domains meet or where a grain boundary between two domains ends. "The details are complicated but, basically, the longer the lever, the greater the amplification on the weakest point," Yakobson said. "The force is concentrated there, and that's where it starts breaking."

"Force on these junctions starts the cracks, and they propagate like cracks in a windshield," said Vasilii Artyukhov, a postdoctoral researcher at Rice and co-author of the paper. "In metals, cracks stop eventually because they become blunt as they propagate. But in brittle materials, that doesn't happen. And graphene is a brittle material, so a crack might go a really long way."

Yakobson said that conceptually, the calculations show what metallurgists recognize as the Hall-Petch Effect, a measure of the strength of crystalline materials with similar grain boundaries. "It's one of the pillars of large-scale material mechanics," he said. "For graphene, we call this a pseudo Hall-Petch, because the effect is very similar even though the mechanism is very different.

"Any defect, of course, does something to the material," Yakobson said. "But this finding is important because you cannot avoid the effect in polycrystalline graphene. It's also ironic, because polycrystals are often considered when larger domains are needed. We show that as it gets larger, it gets weaker.

"If you need a patch of graphene for mechanical performance, you'd better go for perfect monocrystals or graphene with rather small domains that reduce the stress concentration."

Co-authors of the paper are graduate student Zhigong Song and his adviser, Zhiping Xu, an associate professor of engineering mechanics at Tsinghua. Xu is a former researcher in Yakobson's group at Rice. Yakobson is Rice's Karl F. Hasselmann Professor of Mechanical Engineering and Materials Science and professor of chemistry.

PFT: Who has most salary cap room remaining?

Free agency opened 15 days ago.? This year, the initial surge of cash was more limited than ever, more than a few guys settled for one-year deals, and plenty of other players are still waiting to get paid.

For some, the issue is cap space.? For many, it can?t be.? As of Tuesday, March 26, 13 teams still had more than $10 million in spending room for 2013, and five still had more than $20 million, per a source with knowledge of the NFLPA?s calculation of remaining cap room.

Leading the way are the Bengals, who despite numerous re-signings still have $28.9 million to spend.? The Browns come in a close second, with $28.7 million.

The Bucs get the bronze for saving their gold, with $26.8 million.? Also, the Jaguars have $26.6 million, and the Eagles have $26.3 million.

Others with eight figures include the Packers with $18.3 million, the Bills with $16.8 million, the Dolphins with $15.7 million, the Cardinals with $14.0 million, the supposedly spending-to-the-cap Patriots with $13.4 million, the supposedly cap-strapped Jets with $13.0 million, the Colts with $11.7 million, and the Titans with $10.7 million.

This year, teams are required to spend 89 percent of the unadjusted cap.? But that number is determined at least for now on a four-year rolling average, which essentially allows teams to pocket 44 percent of a single year?s spending limit from 2013 through 2016.? Based on the current cap numbers, some teams are well on their way to that number.

Mayo Clinic study: Physician spouses very satisfied in relationships

ROCHESTER, Minn. -- It appears that the majority of spouses/partners of physicians in the United States are happy with their relationships, according to Mayo Clinic research. Of the about 900 spouses/partners of physicians who responded to a national survey, 85 percent said that they were satisfied in their relationship and 80 percent said they would choose a physician spouse/partner again if they could revisit their choice. These values are similar to those of married adults in the U.S. overall. The study appears in the March edition of Mayo Clinic Proceedings.

Consistent with the changing demographic characteristics of U.S. physicians, the study indicated one-fourth of the spouses/partners of physicians are men. The study also found that, independent of age or sex, most spouses/partners work outside the home. And of that group, most work 30 hours per week or more, with nearly 40 percent working full time.

Satisfaction strongly related to the amount of non-sleeping time spent with their physician partners each day. Despite their overall satisfaction, spouses/partners reported their physician partners frequently came home irritable, too tired to engage in home activities, or preoccupied with work.

Physicians' personal relationships are often believed to suffer because of the demanding and consuming nature of their work. Despite these stereotypes, there is little evidence in the findings to suggest physicians have lower-quality relationships or are more likely to go through divorce, says Tait Shanafelt, M.D., first author of the study and a Mayo Clinic hematologist and oncologist.

"The findings challenge a number of stereotypes about physician relationships," says Dr. Shanafelt. "While every relationship has challenges, our research shows that on the whole doctor's spouses and partners are extremely happy in their relationships."

How diabetes drug delays aging in worms

Mar. 28, 2013 ? A widely prescribed type 2 diabetes drug slows down the aging process by mimicking the effects of dieting, according to a study published today using worms to investigate how the drug works.

Following a calorie-restricted diet has been shown to improve health in later life and extend lifespan in a number of animals, ranging from the simple worm to rhesus monkeys. The type 2 diabetes drug metformin has been found to have similar effects in animals but until now it was not clear exactly how the drug delays the aging process.

Researchers supported by the Wellcome Trust and Medical Research Council looked at the effects of metformin on C. elegans worms that were grown in the presence of E. coli bacteria, a relationship similar to that which humans have with the 'healthy' bacteria in our gut. They found that the worms treated with metformin lived longer only when the E. coli strain they were cultured with was sensitive to the drug.

Dr Filipe Cabreiro from the Institute of Healthy aging at UCL, who led the research, explains: "Overall, treatment with metformin adds up to 6 days of life for the worm which is equivalent to around a third of its normal lifespan. It seems to work by altering metabolism in the bacteria that live in the worm, which in turn limits the nutrients that are available to the worm host and has a similar effect to restricting the diet."

Bacteria living in the gut have an important role in helping the host organism to digest and extract nutrition from food. Defects in gut bacteria have been linked to metabolic diseases such as obesity, diabetes, inflammatory bowel disease and cancer. It has also been suggested that gut bacteria may have an impact on the aging process, but this is the first study to suggest a mechanism for how this works.

The team used strains of E. coli with defects in genes that are linked to metabolism and tweaked the levels of nutrients available to tease out which metabolic pathways might be affected by the drug. They found that treatment with metformin disrupted the bacteria's ability to metabolise folate, a type of B-vitamin, and methionine, one of the building blocks of proteins. This limits the nutrients that are available to the worm and mimics the effects of dietary restriction to enable the worms to live longer.

However, when they added an excess of sugar to the diet, the team found that the life-extending effects of metformin were cancelled out. As the drug is used as a treatment for diabetes caused by elevated glucose levels in the blood, this finding is particular relevant for understanding how the drug works in people.

Professor David Gems, who directed the study, said: "We don't know from this study whether metformin has any effect on human aging. The more interesting finding is the suggestion that drugs that alter bacteria in the gut could give us a new way of treating or preventing metabolic diseases like obesity and diabetes."

Metformin is currently one of the most widely prescribed drugs and the findings should help to inform how it is used in patients.

Why some males stick around to raise kids who aren't their own

Per Smiseth

In the animal kingdom, cuckolded males will care for the offspring of interlopers unless female infidelity is common and caring carries a high cost, as with burying beetles.

By Tanya Lewis
LiveScience

No man wants to be cuckolded. But the males of many species actually stick around to raise offspring that aren't their own, so long as the effort doesn't cost them much, new research suggests.

An analysis of several animal studies found that males whose mates had strayed were, on average, 12 percent less likely to care for their offspring than other males. Even so, a high proportion of male animals care for offspring?that may not have been theirs. They did so as long as the likelihood of cuckoldry was low and providing care would not harm the males' own future reproductive prospects. The findings were detailed Tuesday in the journal PLOS Biology.

"The vast majority of species studied show some level of cuckoldry," study leader Charlie Cornwallis of Lund University, Sweden, told LiveScience. The question is, "why should those males continue caring when those offspring don't have their genes?"

Being a caring father?takes work. By one estimate, the amount of effort a typical garden bird expends rearing chicks is the bird-equivalent of cycling the Tour de France. It stands to reason that male animals should only spend this much effort on their own offspring. Yet, bafflingly, research shows that males of many species continue to care for young they did not sire. [The Animal Kingdom's Most Devoted Dads]

Cornwallis and colleagues conducted a meta-analysis of 62 studies of paternity and parental care in 50 different species of insects, fish, birds and mammals. To explain why males care for offspring that someone else might have sired, the researchers considered factors such as whether the males were aware of the female philandering, the likelihood of cuckoldry and the cost of caring for non-biological offspring.

As the researchers wrote in the study, "Are cuckolded males that maintain care blissfully ignorant or selfless dupes?"

Perhaps neither, it turns out. Overall, males care for young from other males unless there's a high risk of being cuckolded, or providing care hurts a male's future prospects of producing his own offspring, the findings suggest.

The results showed a huge variation across species in how males responded to cuckoldry, or perceived cuckoldry. For example, male three-spined stickleback fish provide a high level of parental care because females are less promiscuous and caring for young carries little cost. Chacma baboons, by contrast, suffer rampant cuckoldry and have a lot to lose by caring for the offspring of other males.

Human males fall somewhere in between; they tend to provide less care for children they don't perceive as their own, but that reduction is "quite weak" compared with some other species, Cornwallis said.

Often, "males end up with a mixed bag of some of their offspring and some from other males," Cornwallis said. The cost of caring for those other offspring may be low, and if a male deserts them, he risks losing his own offspring, too.

The study reveals "the simple expectation that you shouldn't care for children that aren't your own is more complex than that," Cornwallis said.

The New Flipboard Lets You Create Your Own Mobile Magazine, Adds Search, Etsy And More

TechCrunch is like most other publications founded before 2011 in that our readers have gone mobile way faster than our products have.?In 2010, 10 percent of our readers were reading us from mobile devices. With the launch of a mobile-friendly version of our website, as well as an increasing breadth of new native apps and mobile magazine Flipboard, mobile platform readers now represent 35 percent of our total traffic. Which is why we’re particularly excited about Flipboard‘s new version coming out tonight. The company is already aggregating our content into a beautiful new format while actually trying to help us develop our mobile business. It provides a solid chunk of our mobile traffic now, and today it has some 50 million total (not monthly unique) visitors. The new version pushes its mission forward in two key ways: universal content search and a way for anyone to create their own “magazine.”?Think of the latter feature as a much sexier personalized homepage than iGoogle and its ilk that you can share with the world. Let’s say you, a TechCrunch reader, want to create your own magazine. You’re mainly visiting us for posts about 3D printing, like this one by John Biggs about a couple of guys who made a robot hand for a boy born without fingers. Using either a new Flipboard bookmarklet (here)?while browsing the web, or the + button now appearing on any story in Flipboard, you pull the robot hand story into a magazine editor window. You’ll then be presented with options to create a new magazine starting with this article or add it to existing ones. If you choose to make a new magazine, you’ll also be able to enter a name, description and category for it to enable easier distribution. Then, Flipboard adds the article headline, body text, images, and any available audio or video. In this case, you’d get the story image, as well as the YouTube video that Biggs had embedded about the robot hand. The story will appear as the lead in your magazine. Attribution to the original publisher is maintained. Any interactions from your readers, including commenting, retweeting and liking, shows up in the original social network. You can also add as many article links, images, videos and soundtracks as you want, creating a permanent record of all your favorite 3D printing stories. If you want to change the cover image and story

Google Launches TV White Spaces Trial In South Africa

Google's first trial to use the unused channels in the broadcast TV spectrum to provide wireless broadband access launched in 2010 in Logan, Ohio. Since then, Google has shown a lot of interest in this topic and today it is launching its second trial. This time it is in Cape Town, South Africa, where Google partnered with a number of local organizations to connect 10 schools to the new wireless broadband network. The idea behind the trial, Google says, is "to show that broadband can be offered over white spaces without interfering with licensed spectrum holders."

By Rolling Stone

A copy of "Sgt. Pepper's Lonely Hearts Club Band"?autographed by all four Beatles up for auction has already surpassed its estimated price by tens of thousands of dollars, The Associated Press reports.

Bidding began at $15,000 with the Dallas-based Heritage Auctions expecting the copy to sell for about $30,000. Early bidding, however, has already pushed the price to $110,500. The auction itself is set for March 30th, and the house says the price could exceed $150,000 by then.

Rare color photos of the Beatles going up for auction

Each respective Beatle penned his name above his head on the record's gatefold, and the auction company's consignment director Gary Shrum says the bidding has "taken on a life of its own."? He added that the spike in the record's cost could be do to the rarity of such a high quality autograph and that "people are responding to that."

Notorious Ivory Coast militia leader killed

ABIDJAN, Ivory Coast (AP) ? A regional official says a notorious militia leader accused of enlisting child soldiers for cross-border raids from Liberia into western Ivory Coast was killed during fighting Saturday.

Claude Koffi Yao Kan, sub-prefect for the western town of Blolequin, said Sunday that Oula? Tako, known as "Tarzan of the West," was among three assailants killed by soldiers responding to the attack. Ivory Coast's United Nations mission says two civilians and a traditional hunter were also killed in the attack on a village 15 miles (25 kilometers) outside Blolequin.

A report last year from Human Rights Watch implicated Tako in a series of raids on villages in western Ivory Coast dating back to July 2011, with witnesses saying he had been involved in the recruitment and training of child soldiers.

0The area around Berezovsky's house in Ascot, Berkshire, has been cordoned off to allow the investigation to take place.

Arizona driver's license battle heads to court

PHOENIX (AP) ? The first major legal battle over President Barack Obama's policy allowing young illegal immigrants to stay in the United States focuses on whether the federal government or state officials have the authority to decide who is legally in the country.

Arizona Gov. Jan Brewer issued an order in August denying driver's licenses for young immigrants who are protected from deportation and have received work permits under the new policy. U.S. District Judge David Campbell heard arguments Friday in a lawsuit seeking to block Brewer's action.

Immigrant groups argue that Arizona's interpretation of the policy is unconstitutional because the state allows some immigrants with work permits to get driver's licenses, but it won't let immigrants protected by Obama's policy pursue any benefits because the state doesn't consider them legal residents.

"States are prohibited from creating their own immigration classifications, and that is exactly what Arizona is doing here," said Jennifer Chang Newell, a lawyer with the American Civil Liberties Union, in the hearing.

Brewer's lawyers claim Obama's policy isn't federal law and that the state has the authority to distinguish between immigrants with work permits who are on the path toward permanent residency and those benefiting from Obama's Deferred Action for Childhood Arrivals program. The state has asked the court to dismiss the lawsuit.

The state's lawyers argued that Arizona is not violating its own policy by refusing to grant licenses to the immigrants in the deferred action program, because the youths haven't been granted legal protections by Congress.

"They have no hope of lawful status," said Douglas Northup, the lead counsel for the governor and the state Department of Transportation. He noted that Congress had the opportunity to pass immigration reform for young immigrants many times in recent years and choose not to do so.

Campbell said he would issue a ruling within the next few weeks.

Arizona's refusal to view those in the deferred action program as legal residents has become the most visible challenge to Obama's announcement in June that it would protect some young immigrants from deportation. The Department of Homeland Security has said immigrants with work permits issued under the policy are lawfully present in the U.S.

The federal program allows illegal immigrants to apply for a two-year renewable work permit. Qualified applicants must have come to the U.S. before they turned 16, be younger than 30, have been in the country for at least five continuous years, be in school or have graduated from high school or a GED program, or have served in the military.

Arizona's policy allows anyone with lawful immigration status to obtain a driver's license, and more than 500 immigrants with work permits have obtained Arizona driver's licenses in recent years. But Arizona officials have said they don't want to extend driver's licenses to those in the new program because they don't believe the youths will be able to stay in the country legally, a nod to a widely held belief among conservatives in Arizona that a judge will eventually rule the administration's policy unconstitutional.

"The Obama amnesty plan doesn't make them legally here," Brewer said shortly after the program was unveiled.

Her tough stance has been cited by immigrant advocacy groups as evidence that Arizona's refusal to grant the young immigrants driver's licenses is a discriminatory policy that violates the U.S. Constitution's equal protection clause.

Immigrant rights advocates filed their lawsuit in November on behalf of five young-adult immigrants who were brought to the U.S. from Mexico as children. They were granted deferred-deportation protections under the Obama administration's policy but were denied licenses in Arizona.

The three groups leading the lawsuit are the ACLU, the National Immigration Law Center and the Mexican American Legal Defense and Education Fund.

The lawsuit seeks class-action status that would let all other young immigrants in Arizona benefiting from the deferred action program to join the lawsuit. Roughly 80,000 immigrants in Arizona are eligible for the program, according to state estimates.

A similar lawsuit was filed in Michigan after officials there initially decided to deny young immigrants licenses, but the case was dropped when the state changed its policy last month.

At least 38 states have agreed to give driver's licenses to immigrants benefiting from the Obama policy, but Nebraska and Ohio officials have also balked.

Dulce Matuz, president of the Arizona Dream Act Coalition and a plaintiff in the case, said finding a job without a driver's license can be difficult because some online applications and interviewers require a license.

"Gov. Brewer wants to dismiss our human dignity. She wants to dismiss our dreams," Matuz said after the hearing.

Strange Sleep Problems, Efficient Packing, Janky-Yet-Awesome Life Hacks, and Google Keep

This week on the podcast we're talking about the crazy things you do in your sleep, how to pack an insanely efficient travel bag, and the jankiest lifehacks that actually work. We're also answering your questions about old Android batteries, OS X's built-in handwriting recognition, and Google's new note taking and universal capture service.

How to Listen to This Week's Episode

Here's how you can listen to our episode:

News and Top Stories

• Mac Trojan Injects Ads Into Chrome, Firefox, and Safari: A new trojan called Trojan.Yontoo.1 is going after Macs. If you run into it, Yontoo.1 prompts you to install a browser plugin called "Free Twit Tube" or something similar. When it's installed, it injects ads into your browser. It requires an install, so if you haven't installed anything weird lately you should be okay, but be careful if you come across a strange download.
• iOS 6.1.3 Fixes Lock Screen Passcode Vulnerability, Available Now: Apple-released a long-expected (but not necessarily desired) update to iOS to fix a lock screen passcode vulnerability that provided anyone capable of completing a complicated process to access your device. Of course, there's a new lock screen vulnerability in iOS 6.1.3 now and if you update to 6.1.3 you (currently) lose the ability to jailbreak so you may want to hold off for now.
• Keep Is Google's New Syncing Notes Service that Quickly Captures Your Thoughts: Google Keep is a new app that seeks to save whatever you're currently thinking about so you don't have to remember. Although not the first app to try and solve this problem, Google's integrated Keep directly into Drive to make it easier to use.
• Gmail Adds Notification Drawer Shortcuts, Faster Search to Android: Google just updated the official Gmail app for Android, adding quick shortcuts to the notification drawer and improved inbox search.
• The Always Up-to-Date Guide to Building a Hackintosh Updated for OS X 10.8.3: OS X 10.8.3 came out last week and we updated our hackintosh guide to support it. Not much has changed since 10.8.2, but we revamped the guide a bit so it's easier to navigate and provided quick access to sample builds you can use when building a new hackintosh from scratch.
• The Crazy Things We Do In Our Sleep (and How to Treat Them): Do you know what you're doing while you're asleep? If you're like millions of other people, you could be talking, walking, or even having sex in your sleep. Here are some of the crazy things we do when we're asleep, and how-if you're someone who suffers from them-you can find some relief.
• How to Fit Two Weeks Worth of Luggage Under the Airplane Seat in Front of You: Back in the day, checking your bag on a trip only cost you 20 minutes of your time after a flight. Now you're lucky if it only costs you $20. With rampant theft, high bag check costs, and overhead bins filled to the brim, learning how to pack efficiently matters more than ever. With the right strategy, you can fit everything you actually need into the seat in front of you.
• Why do Android Apps Need So Many Permissions? It seems like every app developer wants access to so much on my phone! Do they really need all those permissions, or are they just harvesting my data?
• Top 10 Jankiest Life Hacks That Actually Work Wonders: Sometimes, DIY isn't pretty. In fact, sometimes it's downright ugly and rickety, but it's cheap and it works. Let's give some homage to our favorite janky, amazing hacks from over the years.

Questions and Answers

Each week we answer five questions from readers and listeners. Here's what we tackled this week.

• Should I bother using Google Keep? Will it last? Will Google cancel it entirely some day like they did with Reader? What should I do? If you want to use Google Keep, you should. It'll likely be around for several years like most Google services. If Google decides to shut it down at some point, they'll provide time and a means for you to get your data exported and into something else. Products go out of production all the time. Companies close. People die. Loss comes in all kinds of forms and even when it's as bad as losing someone we love, we get past it and manage to love again. So if we, as humans, can lose each other and move on you shouldn't worry about taking a risk with a Google service. As we've seen in the past and will see again with Google Reader, something really great will come from this loss. It just takes a little time. So use Keep if you want to, and don't worry so much. ;)
• I opened up my system preferences today, and there seems to be a new feature since I updated to 10.8.3 called Ink. Seems to deal with handwriting, but I haven't had time to look into it. Ink(well) has been a part of OS X since version 10.2 and recognizes handwriting. It's actually pretty cool and, as Tim demonstrates, isn't something most people know about. It's kind of weird that Apple hides it, but definitely a neat feature to look at if you have any use for it.
• How do I get replacement batteries for old Android phones? I've tried the normal places with no luck. Call the manufacturer and see if they still manufacture the battery, or talk to your carrier and see if you can try a battery for a similar device. Sometimes
• I have a MacBook Pro and a home theater PC (HTPC) running Windows 7. I was wondering if it's possible to view folders located on my HTPC from my Mac laptop and save downloaded or ripped files there? I have found many cross platform synchronization options, but they both sync files both ways. My macbook has a low capacity solid state drive, and would quickly fill if too much media was loaded on it. Any help would be great! Yeah, you just need to set up file sharing. It's very easy and very helpful.
• Should I get a credit card during college to help build up my credit score? Yes, absolutely.
• Should I buy a USB DAC first, or a better set of headphones? Headphones first. They'll make more of a difference than a DAC.

How Do I Submit a Question?

There are two ways to send in your question:

Please keep your questions as brief as possible. This means about 3-5 sentences for emails and 30-60 seconds for calls and videos. Your questions can be specific, but broader questions are generally better because they'll apply to more people. For example, "how can I breathe new life into my old PDA?" is much better than "what can I do with an old HP iPAQ 210?" Either way, we look forward to hearing from you!
