Humans and Rats Think Alike After Making Mistakes

When it comes to learning from mistakes, humans and rats think alike, research suggests.
In a study that tracked how humans and their rodent cousins adapted to errors during a time estimation task, the two species showed similar brain activity in the medial frontal cortex (MFC), which sends signals that synchronize neurons in the part of the brain that controls movement.
The findings suggest rats could serve as models for studying human adaptive control, the process of modifying choices based on experience. This knowledge could be useful in treating psychiatric diseases, such as obsessive compulsive disorder, depression and schizophrenia, the researchers say. [Top 10 Controversial Psychiatric Disorders]
Humans and Rats Think Alike After Making Mistakes"With this rat model of adaptive control, we are now able to examine if novel drugs or other treatment procedures boost the integrity of this system," study researcher James Cavanagh, now a psychology professor at the University of New Mexico, in Albuquerque, said in a statement.
Lesions to the MFC in humans and other animals are known to cause impaired performance in tasks that require learning from mistakes, such as a false start in a race. But the mechanism for how MFC achieved this control wasn't known.
Cavanagh and his colleagues at Brown and Yale Universities measured the brainwaves of rats and humans as both performed a task that involved estimating time in response to a cue.
The researchers saw an increase in low-frequency brainwaves in the MFC of rats and humans after they made errors during the task. The brain activity in this area was synchronized with activity in the motor cortex, the part of the brain that controls muscle movement.
When the scientists used drugs to inactivate the MFC in the rats, the animals were worse at learning from their mistakes on the task, and their MFC brainwaves were less in sync with the motor cortex.
The results, detailed today (Oct. 20) in the journal Nature Neuroscience, "describe a new mechanism for behavioral adaptation through low-frequency oscillations," the authors write. The findings suggest rodents could be a good model for testing new drugs or brain stimulation treatments for diseases involving problems with adaptive control, they add.

Good News for the iPhone at Verizon

With lots of Apple (NASDAQ: AAPL  ) followers panicking about the success of Apple's new iPhones (for no good reason, in my opinion) investors are looking for any source of comfort. Apple won't report its quarterly earnings until Oct. 28, so we won't get the full story on iPhone sales until then.

Fortunately for worried Apple investors,Verizon (NYSE: VZ  ) provided some good news in its quarterly earnings report on Thursday. Of the 7.6 million smartphones activated by Verizon in the third quarter, 51% were iPhones.
This implies that Verizon sold approximately 3.9 million iPhones in the quarter. That's a very strong number, and it suggests Apple will post a massive year-over-year increase in iPhone shipments for the three-month period that ended in September.
A big playerAs the largest wireless carrier in Apple's largest market, Verizon is a key partner for Apple. (AT&T still has the most iPhone users, though, due to its position as the original U.S. iPhone carrier.) In the first half of this year, roughly 11% of all worldwide iPhone activations were on the Verizon network.
Verizon is becoming even more important to Apple over time. The iPhone has been gradually gaining share from Android and BlackBerry devices at Verizon, while Verizon has been winning market share away from AT&T. In last year's quarter ending in September, the iPhone accounted for 46% of all smartphone sales at Verizon, but this year the iPhone's share increased to 51%. This helped drive Verizon's iPhone activations up by roughly 25% year over year, from 3.1 million to 3.9 million.
What does it mean for Apple?Since Verizon's share of worldwide iPhone activations has been fairly stable recently, it is possible to use Verizon's sales numbers to get a rough estimate of how many iPhones Apple sold last quarter. As noted above, in the first two quarters of 2013, Verizon activated 11% of all iPhones sold worldwide. In last year's quarter that closed in September, Verizon had a 12% share.
There are a few factors that could impact Verizon's share of total iPhone activations this quarter. First, as noted before, Verizon has been gaining share within the U.S. mobile market, and the iPhone has been gaining share within Verizon. These factors would tend to increase Verizon's share of worldwide iPhone activations.
On the other hand, this year Apple for the first time launched its new iPhone 5s and iPhone 5c handsets in China at the same time as the U.S. This means that a higher percentage of Apple's iPhone sales may have come from international markets last quarter compared to a year ago. That would reduce Verizon's share of worldwide iPhone sales.

Overall, these two factors should balance each other out and Verizon's 3.9 million iPhones will likely represent 11%-12% of worldwide iPhone sales for last quarter. That implies that Apple may have sold 32 million-35 million iPhones last quarter, which would be 20%-30% higher than the 26.9 million sold in last year's corresponding three-month period. Anything in that range would be a great result, especially since Apple did not release a lower-margin "cheap" iPhone to gain market share.
Foolish conclusionIt's important to remember that there are a lot of moving parts involved in Apple's quarterly iPhone sales tally. For instance, it's possible that Verizon had a better initial supply of the new iPhones this year compared to last year. Therefore, investors shouldn't assume that a 25% increase at Verizon translates directly to a 25% increase in worldwide iPhone sales.
Nevertheless, Verizon's strong iPhone activation numbers -- combined with Apple's big opening weekend sales tally -- should make investors comfortable that Apple sold plenty of iPhones last quarter. Since the iPhone is responsible for the majority of Apple's revenue and profit, this bodes well for the company's quarterly earnings. There's no need to worry about Apple: It's doing just fine!

Nokia Lumia 1520 release date nears: How will it do in USA market?

Within a few days it is going to be out as Nokia Lumia 1520 release date nears. Many wonder how the phablet will do in USA market?
Finnish mobile giant Nokia’s forthcoming phablet Lumia 1520 is going to get a good response in US market and elsewhere too. The smartphone maker is all set to launch a huge 6-inch handset with all the top trappings of any other phablet from top smartphone manufacturers like Samsung and Sony. with the exception of Apple almost all the top smartphone makers have launched a few phablets. This includes Sony, HTC, LG and of course Samsung. In many markets in Asia and even Europe huge handsets are in great demand and every smartphone manufacturer has his own handset in this genre.
Nokia Lumia 1520 that comes with top of the line specifications and features is definitely going to be a big threat to the other phablets including market leader Samsung Galaxy Note 3, Sony Xperia Z Ultra and many others. There is no doubt that Nokia despite starting late is beginning to catch up with the entrenched market leaders in both smartphone and phablet markets. It is going to be the first 1080p smartphone running Windows Phone. We have already seen several images and screenshots of the device, and it is now to go official on October 22 in Nokia World to be taken place in Abdu Dhabi. Unofficial sources claim that the device is a 6-incher, and it touts a 20MP rear camera and a 3390mAh battery.
The handset will not just be coming with FullHD display it will also come with very powerful processor. Under the cover, the fabled Lumia 1520 will feature a solid quad-core Snapdragon 800 processor, at least 2GB of RAM and other quality specs. It will be running on the Windows Phone 8’s upcoming GDR 3 update. Plus, it will have Nokia Glance Background on board. Nokia might be targeting the new Lumia 1520 as a stiff rival against the key Android phablets out there. Majorly we have three high-end phablets out in stores; Samsung Galaxy Note 3, Sony Xperia Z Ultra and HTC One Max. The Windows Phone 8 running Lumia 1520 will surely act as a strong alternative to all these models.
The demand for the phablet will be quite high as it comes with great specifications and good features. Nokia is seemingly all set to launch the Lumia 1520 at its upcoming media event. Alongside the 1520, the company will also apparently roll out its new Lumia 525 budget model upgrade, a longtime rumored Lumia Tablet, a “Lumia” laptop and a set of Asha phones. The tech world is crazily in waiting for the forthcoming Nokia media event.

On Tuesday, Apple Will Make You Want To Buy An Apple TV For The Holidays


Apple AAPL +0.87% is in the enviable position that its customers routinely think about not just if they will upgrade a given product but merely when. So if you are Apple, a big part of your growth strategy is to figure out how to balance a schedule of product updates with improvements that you can actually deliver. As Apple design lead Jony Ive says, “Different and new is relatively easy. Doing something that’s genuinely better is very hard.”
It is good for customers to be clamoring for a new iPhone, for instance, but not so good if they get frustrated by a long release cycle and go buy a Samsung. For this coming Tuesday’s event, it seems virtually certain that Apple will announce new iPads (both full size and a new Retina Mini), as well as new MacBook Pros with Haswell chips that will ship with the next version of OS X, Mavericks. All three of these, the iPads, the MacBook Pros and OS X, are on a reasonable schedule to match consumer demand.
In the long overdue category, however, is the Apple TV. Apple has not released a “generation” update of its “puck” since March of 2012 (it did come out with a minor upgrade in January of this year.) This has put a lot of Apple users, myself included, in the position of not wanting to buy an Apple TV because a new one must be just about to come out. This kind of lame duck gridlock is exactly what Apple tries to avoid with its product roll outs.
Three recent bits of news suggest that Apple will announce something significant about Apple TV on Tuesday that I predict will convince me and millions of others to get off the fence and buy one of the cute little $99 devices. (It is easy, of course, for me to make a prediction about myself!)
First, as Mike Elgan of Cult of Mac has detailed inthis post, Apple has been making a lot of new content deals with cable systems and content providers that are on their way to attaining a critical mass for consumers. Elgan writes that “for high-end TV enthusiasts, the Apple TV experience will become ‘indispensable,’ while individual cable subscriptions will be ‘dispensable.’” Deals with HBO, ESPN , Disney and perhaps now AMC are making Apple TV an all-in-one solution for more an more consumers.
Second, strange sightings on the French and German Amazon sites indicated the current Apple TV as out of stock but coming in stock on October 23, a day after the Apple announcement. This may be as erroneous as a previous rumor about a consignment recieved by Apple of “set top boxes” from China in September, but both rumors align with the common sense notion that Apple is due to drop a new Apple TV generation.
Third, Apple insider MG Siegler tweeted and then partially retracted the idea that a significant hardware refresh for Apple TV was coming this Fall. (His tweet read, “I guess those excited about a software refresh in a week are gonna be *really* excited when new Apple TV hardware is unveiled next month.”) What he seems certain on is that a new version of the Apple TV software will be appearing to coincide with iOS 7, Mavericks and all of these new content deals. In his post yesterday, however, he writes that, “I have heard is that the Apple TV project has been delayed a bit. That doesn’t mean we won’t see an Apple TV update at the event — we could see an updated unit with a spec bump or something. But the thing to be more excited about, the device with some sort of newfangled control system, doesn’t seem like it’s ready just yet.”
Furthermore, Elgan goes on to paint a picture of how Apple’s content deals will slowly but surely turn the tables on the cable companies as it builds audience and simultaneously hold the line on pricing. “As everyone races each other to the bottom of TV content pricing,” he writes, “Apple will offer a superior experience for TV while holding the line on pricing, eventually becoming the last place where content creators can actually made money from subscription service.”
Taken together, these threads weave together three possible scenarios for Tuesday. The first is that, as Siegler suggests, there is no magical new Apple TV hardware on offer, and in fact no new Apple TV hardware at all, just a significant software update. The second is that there will be a modest “spec bump” on the existing Apple TV but no wholly new control system or other revolutionary feature. The third would be a significant hardware upgrade along the lines of Siegler’s original tweet.
I’m going to predict that Apple will present scenario #2 on Tuesday. The fact is that any of these will make my want to buy an Apple TV in time for the holidays. Elgan says that on top of the 13 million Apple TV units sold thus far, “With compelling enough content offerings, that number could triple by the end of next year.” That’s no iPhone (or even iPad) but it’s beginning to sound more than a mere string-pulling for Apple.
The reason I am betting on the second narrative is that it is within Apple’s powers to make an upgraded Apple TV unit with specs to match the new OSs and content offerings. And although a big software upgrade and the notion that a really significant hardware upgrade is not in the offing will boost Apple TV unit sales (assuming they are in stock!) an actual new product to buy will boost them more. Given the inventory problems Apple has had with its iPhone launch, the somewhat hurried release of iOS 7 and the longer-than-expected gestation of OS X Mavericks, it is not hard to imagine that a bigger hardware refresh would be behind schedule. Best of all, in this case, would be if Apple signaled that a modestly improved hardware unit would be capable of handling significant software updates in the future capable of delivering the full experience that Apple has long promised but so far not quite manifested.

100 Facebook friends show up to defend bullied student -- and he even gets an apology

A high-school bully decided to apologize after 100 Facebook users showed up to rally behind a boy he had accused of having no friends.
Halsey Parkerson stands in front of some of the 50 cars that showed up to his anti-bullying rally (KATU)
South Salem High School Junior Halsey Parkerson got a huge surprise on Friday, when more than 50 cars showed up at his school to help him stand up to a local bully.
KATU reports that on Thursday, Parkerson’s aunt had stopped by his school to have lunch with him. That’s when a bully began taunting Parkerson and saying it didn’t matter because he “didn’t have any friends.”
Parkerson told his aunt that it happened “all the time.” In response, she reached out to an online car club she belongs to on Facebook and asked people to show up to the school for lunch on Friday.
In response, more than 50 cars showed up, carrying at least 100 people. And KATU's 
"It's just unbelievable," Parkerson told KATU. "I now know whenever I get bullied I'll raise my head up and say, 'Sorry, I have too many friends to think I'm being bullied.'"
And the story just gets better from there. When Parkerson and his new friends approached the unnamed bully, he offered Parkerson a high-five and an apology.
“I apologize,” the student, whose identity is being withheld, told Parkerson. “I apologize and I take it back.”
When the mass of cars first showed up at South Salem High School on Friday, Principal David Phelps was immediately alerted of the unusual incident. However, once he learned why all of the visitors had showed up, he decided to let the event continue.

A study from the National Center for Education Statistics estimates that a third of all students have experienced bullying in some form. An even as awareness over school bullying has risen in recent years, the news continues to see tragic stories of children and teens who have been bullied by classmates and peers. CNN reported that a day after an Illinois high school showed students a video on bullying a student committed suicide. When his Brad Lewis found his 15-year-old son's suicide note, he said his son said bullying had pushed him over the edge.
Since Friday, Parkerson said he has received an outpouring of support. On his Facebook page, he wrote:
“Thanks to everyone who was there with me and my family thanks also to the ones who could not make it by all you making a difference,” he wrote. “I truly mean it I’m tearing up thanks guys for standing up with me and helping me make a difference!!”
Parkerson said that while he’s grateful for the incredible show up support, he realizes it was not about him specifically. Rather, it was a public display meant to encourage anyone who is being bullied to seek out support.

"If you're being bullied, stand up and express yourself," Parkerson said. "This is one glorious day."
