iMore Editors' Choice: Spaceteam, Elago M2 dock, Moviegram, and more

iMore Editors' Choice: Spaceteam, Elago M2 dock, Moviegram, and more

Every week, the editors and writers at iMore carefully select some of our favorite, most useful, most extraordinary apps, accessories, gadgets, and websites. This week's selections include a few games, an Apple service that is easy to take for granted, an awesome iPhone dock, and a fitness app.

iCloud - Chris Oldroyd

This week I have chosen a built in service provided by Apple that up until recently I totally took for granted. This week, iCloud totally saved my bacon after a disastrous problem with a jailbreak app update rendered my iPhone 5 unusable, first thing in the morning, 60 minutes before heading to work.

I am a casual jailbreaker, I did the jailbreak a couple of days after it was released and all I had installed was Lockinfo and BiteSMS. They both had updates that morning and after the updates, something went seriously wrong. The iPhone 5 restarted and the screen was all distorted with multi colors everywhere and the actual iPhone home screen was in the top corner a quarter of its normal size; it was all a bit weird to say the least.

I managed to get into the Settings and initiate the Erase All Content and Settings function but that wouldn?t complete so I had to do a complete restore via iTunes on my PC. I then ran out of time and had to leave for my meeting. Thankfully, I had all of my apps and settings backed up to iCloud and by using a MiFi wireless network in my car I managed to get all of my apps, settings, contacts and pictures restored on route and my iPhone 5 was back to normal just before I got to the meeting?..what a relief!

iCloud is so underrated, it works in the background backing up your device every night when it?s connected to power and WiFi and is a real life saver when something goes wrong like it did for me. I have learned my lesson with jailbreaking for now at least ad I am so grateful to iCloud for making the whole process of getting things back to normal as painless as possible!

Moviegram - Joseph Keller

Moviegram is a great way to look up movies when you?re trying to decide which one you go see. By pulling in ratings from three different sources, Rotten Tomatoes, Metacritic, and IMDb, Moviegram can give you a comprehensive picture on whether or not a movie is worth seeing. You can either search for movies or select them from an available list. Each movie?s page will display basic information such as a synopsis, the cast, and a trailer if one is available. Tap on a cast member to see their other films. Moviegram is a universal app, and available for free, with a $0.99 in-app purchase to remove the ads.

Elago M2 dock for iPhone and iPad - Ally Kazmucha

I've been on the hunt for a dock for my iPhone 5 ever since Apple didn't release one. I'm not a fan of cases so I've never had a problem with the stock Apple version. After coming up empty handed several times, I finally found one that looked like not only would it work for my iPhone, but my iPad mini and regular sized iPad as well, and that was the Elago M2.

When you spend as much time as I do with apps and reviewing them, it's nice to dock your iPhone or iPad next to your computer so you don't have to keep picking it up time and again to view something. I've found it supports any device in any orientation extremely well. The Elago M2 dock is not only versatile, but super sharp looking. It comes in both black and silver so regardless what iPhone or iPad you have, you'll have one that matches. It's also a lot cheaper than some options out there.

The only issue I've found is that the back is flat metal which made me a little nervous when it comes to scratching. I didn't have any issues but I also easily remedied that by sticking a small rubber circle on the back to add some extra cushion. Not necessary but a cheap way to add a little extra padding and grip. If you're a dock fan and haven't found a perfect one yet, I'd highly recommend checking out the Elago M2.

Metal Slug 2 - Chris Parsons

If you're looking for a run-and-gun action shooter, then there is nothing really better than the classic Metal Slug. Unless of course, you're speaking of Metal Slug 2! Ported from the original NEOGEO, Metal Slug 2 is builds off of the classic while adding some new great features into the mix called "Mission Mode". New characters, new weapons and more will keep you pounding away at Metal Slug 2. It's $3.99 right now but it has tremendous replay value.

Spaceteam - Rene Ritchie

I was sitting at a party at Macworld|iWorld 2013, minding my own business, when Arnold Kim from MacRumors broke out Spaceteam and began to play it with some of the designers and game developers there. Everything went straight to hell from there.

Here's why -- Spaceteam is a multiplayer game where you connect two iOS devices over a shared Wi-Fi network, or a direct Bluetooth connection, and then go into co-op chaos. The goal is to take your ship to collective warp, and you're given instructions -- convoluted, gobbledegook instructions -- on how to do so, but the buttons you have to press and levels you have to adjust might be on your device? or they might be on someone else's.

And so the yelling begins. Soon everyone is barking out directions, hunting furiously to act on what they see, and what's being screamed at them, in an effort to get to hyperspace.

It gets faster and more furious as you go on, and the interface starts falling apart on you.

It's not pretty. But it's pretty awesome.

Two Hundred Situps - Leanna Lofte

Three weeks ago, I gave birth to my second daughter and it's time for me to get back into shape. One of the big problem areas is my core, so I've turned to Two Hundred Situps to help get toned up. I've only started using it today, but I've gone through the One Hundred Situps app by the same developer and it was great.

The way Two Hundred Situps works is that you take an initial "test" which is simply to do as many situps as you can. The app then develops a program for you that will have you doing 200 consecutive situps in six weeks -- and all it takes is 30 minutes a week!

Considering it's the end of Exercise Week in Mobile Nations Fitness Month, now is the perfect time to pick this one up!

Your choice?

Now that we've chosen our favorites for the week, we want to hear yours! Did you pick up a killer app, accessory, or game this week? Let us know in the comments below!

Obama's State of the Union will focus on economy

WASHINGTON (AP) ? President Barack Obama will focus his State of the Union address on boosting job creation and economic growth at a time of high unemployment, underscoring the degree to which the economy could threaten his ability to pursue second-term priorities such as gun control, immigration policy and climate change.

Obama also may use Tuesday's prime-time address before a joint session of Congress to announce the next steps for concluding the U.S.-led war in Afghanistan by the end of 2014.

Obama's State of the Union marks his second high-profile speech to the nation in about three weeks, after his inaugural address Jan. 21 that opened his second term. White House aides see the two speeches as complementary, with Tuesday's address aimed at providing specifics to back up some of the Inauguration Day's lofty liberal rhetoric.

The president previewed the address during a meeting Thursday with House Democrats and said he would speak "about making sure that we're focused on job creation here in the United States of America." Obama said he would try to accomplish that by calling for improvements in education, boosting clean energy production, and reducing the deficit in ways that don't burden the middle class, the poor or the elderly.

While those priorities may be cheered by some Democrats, they're certain to be met with skepticism or outright opposition from many congressional Republicans, especially in the GOP-controlled House. The parties are at odds over ways to reduce the deficit. Republicans favor spending cuts; Obama prefers a combination of spending cuts and increasing tax revenue.

The president said he would address taxes and looming across-the-board budget cuts, known as the sequester, in the speech. The White House and Congress have pushed back the automatic cuts once, and Obama wants to do it again in order to create an opening for a larger deficit reduction deal.

"I am prepared, eager and anxious to do a big deal, a big package that ends this governance by crisis where every two weeks or every two months or every six months we are threatening this hard-won recovery," he said last week.

The economy has rebounded significantly from the depths of the recession and has taken a back seat for Obama since he won re-election in November. He's instead focused on campaigns to overhaul the nation's patchwork immigration laws and enact stricter gun control measures following the massacre of 20 schoolchildren in Newtown, Conn., in December.

The president also raised expectations for action this year on climate change after devoting a significant amount of time to the issue in his address at the inauguration.

But the unemployment rate is persistently high at 7.9 percent, economic growth slowed last quarter and consumer confidence is falling, so the economy could upend Obama's plans to pursue a broader domestic agenda in his final four years in office.

Tony Fratto, who worked in the White House during President George W. Bush's second term, said Obama has to show the public that he's still focused on the economy before he can get their full support for his other proposals.

"We're not in a position where he can blame anybody else for the economy now," Fratto said, "Now it's his economy."

Obama is expected to use his address to press lawmakers to back his immigration overhaul, which includes a pathway to citizenship for 11 million illegal immigrants, and his gun control proposals, including universal background checks and a ban on assault weapons.

Voting rights groups expect the president to call for changes that would make it easier for people to vote.

"I think it's important to be able to do more than one thing at a time," said David Axelrod, who served as senior adviser in the White House and Obama's re-election campaign. "But the economy is an ongoing and significant challenge that you have to keep working on."

While the centerpiece of Obama's address is expected to be his domestic agenda, the president sees a chance to outline the next steps in bringing the protracted war in Afghanistan to an end. He's facing two pressing decisions: the size and scope of the U.S. military presence in Afghanistan after the war formally ends late next year, and the next phase of the troop drawdown this year.

More than 60,000 U.S. troops are in Afghanistan.

The president could update the public on cuts to the number of U.S. nuclear weapons, a priority for his administration. Vice President Joe Biden recently told a security conference in Germany that Obama probably would use the State of the Union to discuss "advancing a comprehensive nuclear agenda to strengthen the nonproliferation regime, reduce global stockpiles and secure nuclear materials."

White House allies are nudging Obama's team to move forward on a plan to expand education for children before they enter kindergarten. They are reminding Obama's political aides that female voters gave the president a second term, serving up a 10-point gender gap.

Obama carried 55 percent of female voters, many of whom are looking to the White House for their reward. While groups such as Latinos and gays have seen policy initiatives since Election Day, women's groups have not received the same kinds of rollouts.

Florida Sen. Marco Rubio, a rising Republican star and potential 2016 presidential candidate, will deliver the GOP response following Obama's address to Congress.

The president will follow up his speech with trips across the country to promote his calls for job creation. Stops are planned Wednesday in Asheville, N.C., and Thursday in Atlanta.

Obama's speechwriters started working on Tuesday's address shortly after the November election. The process is being led for the first time by Cody Keenan, who is taking over as the president's chief speechwriter.

New design for basic component of computer chips: Researchers demonstrate record-setting p-type transistor

Jan. 2, 2013 ? Almost all computer chips use two types of transistors: one called p-type, for positive, and one called n-type, for negative. Improving the performance of the chip as a whole requires parallel improvements in both types.

At the IEEE's International Electron Devices Meeting (IEDM) in December, researchers from MIT's Microsystems Technology Laboratories (MTL) presented a p-type transistor with the highest "carrier mobility" yet measured. By that standard, the device is twice as fast as previous experimental p-type transistors and almost four times as fast as the best commercial p-type transistors.

Like other experimental high-performance transistors, the new device derives its speed from its use of a material other than silicon: in this case, germanium. Alloys of germanium are already found in commercial chips, so germanium transistors could be easier to integrate into existing chip-manufacturing processes than transistors made from more exotic materials.

The new transistor also features what's called a trigate design, which could solve some of the problems that plague computer circuits at extremely small sizes (and which Intel has already introduced in its most advanced chip lines). For all these reasons, the new device offers a tantalizing path forward for the microchip industry -- one that could help sustain the rapid increases in computing power, known as Moore's Law, that consumers have come to expect.

Pluses and minuses

A transistor is basically a switch: In one position, it allows charged particles to flow through it; in the other position, it doesn't. In an n-type transistor, the particles -- or charge carriers -- are electrons, and their flow produces an ordinary electrical current.

In a p-type transistor, on the other hand, the charge carriers are positively charged "holes." A p-type semiconductor doesn't have enough electrons to balance out the positive charges of its atoms; as electrons hop back and forth between atoms, trying futilely to keep them electrically balanced, holes flow through the semiconductor, in much the way waves propagate across water molecules that locally move back and forth by very small distances.

"Carrier mobility" measures how quickly charge carriers -- whether positive or negative -- move in the presence of an electric field. Increased mobility can translate into either faster transistor switching speeds, at a fixed voltage, or lower voltage for the same switching speed.

For decades, each logic element in a computer chip has consisted of complementary n-type and p-type transistors whose clever arrangement drastically reduces the chip's power consumption. In general, it's easier to improve carrier mobility in n-type transistors; the MTL researchers' new device demonstrates that p-type transistors should be able to keep up.

Handling the strain

Judy Hoyt, a professor of electrical engineering and computer science; her graduate students Winston Chern, lead author on the new paper, and James T. Teherani; Pouya Hashemi, who was an MIT postdoc at the time and is now with IBM; Dimitri Antoniadis, the Ray and Maria Stata Professor of Electrical Engineering; and colleagues at MIT and the University of British Columbia achieved their record-setting hole mobility by "straining" the germanium in their transistor -- forcing its atoms closer together than they'd ordinarily find comfortable. To do that, they grew the germanium on top of several different layers of silicon and a silicon-germanium composite. The germanium atoms naturally try to line up with the atoms of the layers beneath them, which compresses them together.

"It's kind of a unique set of material structures that we had to do, and that was actually fabricated here, in the MTL," Hoyt says. "That's what enables us to explore these materials at the limits. You can't buy them at this point."

"These high-strain layers want to break," Teherani adds. "We're particularly successful at growing these high-strain layers and keeping them strained without defects." Indeed, Hoyt is one of the pioneers of strained-silicon transistors, a technology found today in almost all commercial computer chips. At last year's IEDM, she and Eugene Fitzgerald, the Flemings-SMA Professor of Materials Science and Engineering at MIT, received the IEEE's Andrew S. Grove Award for outstanding contributions to solid-state devices and technology. The award announcement cited Hoyt's "groundbreaking contributions involving strained-silicon semiconductor materials."

Gatekeeping

Another crucial aspect of the new transistor is its trigate design. If a transistor is a switch, throwing the switch means applying a charge to the transistor's "gate." In a conventional transistor, the gate sits on top of the "channel," through which the charge carriers flow. As transistors have grown smaller, their gates have shrunk, too. But at smaller sizes, that type of lockstep miniaturization won't work: Gates will become too small to reliably switch transistors off.

In the trigate design, the channels rise above the surface of the chip, like boxcars sitting in a train yard. To increase its surface area, the gate is wrapped around the channel's three exposed sides -- hence the term "trigate." By demonstrating that they can achieve high hole mobility in trigate transistors, Hoyt and her team have also shown that their approach will remain useful in the chips of the future.

The MIT researchers' work was supported by the U.S. Defense Advanced Research Projects Agency and the Semiconductor Research Corporation.

Childhood Obesity | Your Health Journal

By Marcela De Vivo

overweighchildsmallChildhood obesity isn?t just a problem in the United States ? it?s an epidemic.

According to the Centers for Disease Control and Prevention (CDC), childhood obesity has nearly tripled since 1970, with nearly 20-percent of children between the ages of six and eleven considered obese.

The obesity rate has also risen for adolescents. Approximately 18-percent of adolescents between 12 and 19 are obese, and many more are overweight and on the verge of obesity.

Luckily, there are some things you can do as a parent to help your child lose weight and get healthy.

It?s important that your child loses weight and begins living a healthy life now to avoid serious potential health problems later on in life.

Causes of Childhood Obesity

While many parents think that childhood obesity is related to genetic traits, there really aren?t any genetic reasons that young child should be obese according to the Mayo Clinic.

While many parents think that childhood obesity is related to genetic traits, there really aren?t any genetic reasons that young child should be obese according to the Mayo Clinic.

Genetic disorders can cause problems with weight gain and retention ? particularly thyroid disorders ? though these are fairly rare in most young children.

The most common causes of childhood obesity are poor diet and lack of exercise.

Simply put, children that are obese are likely consuming too many calories and not burning enough of them through regular physical activity, resulting in weight gain.

Change Your Child?s Eating Habits

If your child is obese, you need to take the initiative when it comes to changing your child?s eating habits.

fruitAfter all, you probably prepare most of their meals ? or at the very least, pay for them.

A child?s diet should be rich in lean protein sources like skinless chicken, turkey, fish and beans. Protein is essential for growing children, but high-fat options like ground beef and pork can lead to weight gain. If you?re going to make burgers at home, opt for at least 98% lean ground beef, your child won?t taste the difference.

Children also need to eat plenty of vegetables. Many children don?t want to eat their vegetables, but as a parent, it?s your job to make sure they do. Try serving raw broccoli, carrots or celery with fat-free, low-calorie dressing for dipping. If your child just won?t eat their vegetables, try to sneak them into foods that they like to get them used to their taste.

Lasagna anyone? Meaty, cheesy goodness can do wonders concealing broccoli, asparagus, bell peppers, mushrooms etc. Switch to whole wheat or grain pasta too. Low-fat dairy products help build strong bones and provide calcium, both of which are essential for growing children. Instead of high-fat products like chocolate milk, choose low-fat versions. Low-fat dairy options like fat-free yogurt also make excellent alternatives to high-fat desserts like ice cream.

Getting your kids involved with the food that they?re eating can also help them to try new things. When preparing meals for your child, ask them to pick out vegetables or to assemble a salad for the whole family with a group of already prepared ingredients.

Many kids are willing to eat foods that they wouldn?t otherwise if they have a hand in their preparation. This also sets your kids up for healthy eating habits when they?re adults and living on their own. It?s also important that you limit how many sweet treats your child gets.

Soda, cookies, cakes and candy should be looked at as special treat, not something that should be a part of or follow every meal. You should also replace high-fat versions of desserts with lower calorie ones, like frozen yogurt for ice cream. Sitting down and eating meals with your child can also help develop healthy eating habits. Turn the television off and have a conversation. Eating in front of the television or while doing schoolwork can result in overeating because your brain is too busy focusing on the television to tell you that you?re full.

Exercise

boysoccerExercise is an important part of fighting childhood obesity. Exercise is also important for adults, and it can help to prevent weight gain and other health problems later in life. Setting your child on the path to regular exercise will benefit them throughout their life. It?s important to remember that you don?t need to put your child on an exercise plan that they hate, but rather to get them to do physical activities that they enjoy. Find activities that your child likes and get them involved. For many kids, intramural sports are a lot more enjoyable than riding an exercise bicycle or jogging.

Lead by Example

As a parent, it?s your job to show your child how to live a healthy life. That means that you need to find time to exercise too. Consider exercising with your child. Toss a football, shoot a basketball or even go bowling or ice skating. Any physical activity will help your child lose weight and develop a healthy active lifestyle.

Lackluster Arsenal draws 1-1 at Southampton

Associated Press Sports

updated 3:34 p.m. ET Jan. 1, 2013

SOUTHAMPTON, England (AP) -Arsenal lost valuable ground in the chase for a top-four spot in the Premier League by drawing 1-1 at Southampton on Tuesday, needing an own goal to earn a point after a lackluster display at St. Mary's.

Guly do Prado stretched to deflect Theo Walcott's free kick into his own net in the 41st minute, canceling out Southampton's opener scored by Uruguay forward Gaston Ramirez.

Arsenal lacked the spark that saw the team thrash Newcastle 7-3 on Saturday and was outplayed at times by the home side, which climbed out of the bottom three with the draw.

Arsene Wenger's team is provisionally fifth - five points behind north London rival Tottenham, which beat Reading 3-1 earlier Saturday, but with a game in hand.
