Future of music streaming sounds big on popularity, but not profits ...

Apple promised the iPod would put 1,000 songs in users? pockets, turning the iTunes Music Store into an overnight success.

14 things you didn?t know you could do with your iPad

The iPad has some tricks up its sleeve that you might not know about.

While many complain about the software being ?stale? (well, until iOS 7 comes sometime this fall), there are many features on the iPad that you can take advantage of if you know the right settings, gestures, or apps. Continue reading.

But it?s not that simple for the next generation of digital music distributors, who are promising to put every song ever in a users? pocket, and it might take years to see whether their services will be anywhere near as lucrative.

A new generation of music services is touting catalogues of millions of songs, largely accessible via WiFi or cellular streaming, to laptops, tablets or mobile phones.?Though not every service is available in all countries, the list of competitors runs long. Relying on either monthly subscriptions, or short, in-stream ads, there are the heavyweights ? U.S.-based pioneer Pandora and the global juggernaut Spotify ? alongside European and Asian favourite Deezer, and smaller but competitive entrants such as Rdio and Songza accessible in Canada.

?The industry right now ? there?s a lot going on,? said Chris Becherer, vice-president of Rdio?s product team. ?It seems like there?s a new streaming service every week coming online.?

These services are popular, which is in part why so many new entrants are eager to compete ? but they they are not yet successful. And while the secret to success remains elusive so far, two recent models show the most promise.

?You can sort of split them between machine curation and human curation,? said Anthony Mullen, a Forrester senior analyst who studies the industry.

?Human curation has always been very important in music ? but the other approach is obviously infinitely more scalable.?

Services such as Spotify, Rdio and Deezer skew towards the on-demand model, where the onus is typically on the user and his or her friends to choose songs and curate playlists from a vast catalogue of music, both new and old.

But for service providers, this level of control comes at a very literal cost, as licensing rights are typically more expensive.

It seems like there?s a new streaming service every week coming online

The other model favoured by Pandora, Songza and others is more akin to Internet radio. A user can choose his or her favourite song, artist or genre, and complex musical algorithms are left to generate endless personalized stations filled with similar types of songs. Licensing rights are cheaper, because like radio, users have less control over what they can listen to at any given time, but is perceived by some to be a more convenient listening experience ? one that is less hands-on.

Both Google and Apple have announced music services with similar radio-like functionality in recent months.

?I think there is a very distinct need for both kind of services, as there always has been. Like listening to physical records and listening to radio, they?re not exclusive,? said Aapo Markkanen, a senior analyst with technology market intelligence firm ABI Research. ?Both of them will be used.?

Rdio, in fact, is betting that the two models don?t have to exist in opposition, but can actually complement one another quite well.

On Thursday, the San Francisco-based streaming service announced a new feature called Stations. It generates personalized radio-like stations based on a user?s favourite songs and artists, as well as Twitter follows and Facebook likes.

Pick a song, artist, genre or even the musical collection of a friend, and Rdio will generate a customizable playlist populated with other songs it thinks you?ll like,?similar to what competing services such as Pandora and Songza already do ? that other side of the streaming music coin.

?We really see these two modes of listening as certainly related, and as something that everyone has a desire for. But the services have been sort of split down the middle,? said Mr. Becherer.

?Everybody has an appetite for both. It doesn?t make sense that people should have to go to two different services.?

Mr. Becherer said the team was surprised to find that nearly half of Rdio?s users go outside of the service to listen to radio-style music stations, and that the new Stations feature was meant ?to provide a seamless transition from passive listening to active listening.?

That makes Rdio unique amongst streaming services, in that it tries to reconcile the two.

The question, then, is whether such features will convince users to pay ? particularly when content no longer will.?In the early days of online music streaming and download services, companies sparred over catalogue quality and licensing agreements. What Rdio had, Spotify didn?t ? and what you couldn?t get from either, from iTunes you probably did.

And while the catalogue of music still matters ? you still won?t find The Beatles streaming, for example, and there are other notable holdouts like Led Zeppelin ? it matters less than it once did. Rather, it?s all about the features, the functionality ? and, increasingly, your friends ? that music services hope will give them the edge.

In an interview with the Financial Post in May, Songza?s co-founder and chief executive Elias Roman said that ?the unit of analysis for most users most of the time is not artists or songs, but playlists, and how those playlists relate to a situation.?

That?s part of the reason why the his team redesigned the interface to make it easier for users to listen to their favourite artists and jump more quickly?into playlists.?For example, when a user shakes their device, a box now appears, in which he or she can type keywords such as ?BBQ? or ?driving? from which, based on listening history, Songza will select a playlist of appropriate songs ? similar in theory to an Rdio or Pandora, but also different.

Earlier this week, Mr. Elias also launched its premium Club Songza service on Apple devices ? an in-app purchase subscription priced at $3.99 per month that removes ads and includes exclusive content such as artist-curated playlists.

Songza, which is only available in the U.S. and Canada, is otherwise available for free.

It?s a similar to Pandora and Spotify, which also offer free listening tiers, and charge heavier users, or those who wish to remove ads. On-demand services such as Rdio and Deezer are similarly priced ? usually between $4.99 and $9.99 a month ? depending on whether a user also wishes to stream music from his or her phone. And if they wish to pay at all.

?It?s partly a cultural thing. I think it also has to do with demographics,? said Mr. Markkanen. ?Some countries with a fairly high medium age, those people are still more willing to pay for downloads and physical CDs.?

He also cited infrastructure factors, where users might be less inclined to pay for subscriptions, particularly on mobile deices, in countries where wireless connectivity is slow, or bandwidth caps make streaming lots of music expensive.

But ultimately, he believes, it?s ease of use that often wins users over.

?It?s more convenient than piracy,? Mr. Markkanen said. ?It?s platform agnostic and follows you around in the cloud.?

A forecast done by ABI Research at the beginning of August estimated a total of 29 million users worldwide would be paying for on-demand music streaming services by the end of 2013.

Spotify leads the pack with an estimated 9 million paid users, or 32%, with Deezer trailing in second. Spotify currently has 6 million paid subscribers, while Deezer claims 4 million.

As of March, Songza had over 4.7 million monthly active users.

And while Mr. Aapo estimates that Rdio only has slightly more than one million paying subscribers currently, he believes that number will reach 1.2 million by year?s end.

Rdio has historically declined to provide official user numbers for the service.

?I think Rdio is just basically extending their offering to look attractive in a very, very competitive marketplace,? Mr. Mullen said of Stations, and characterized the current state of the music streaming business as one where consumers are ?paralyzed by choice?

Mr. Markkanen believes this is part of the reason why consolidation of services is inevitable ? and even employees he?s spoken with at some the big services agree that there are too many players for all to succeed in the long term.

?A lot of services are going to have almost identical footprints in terms of countries they operate, and also identical catalogues,? he said ? making it harder to differentiate on features, and also succeed at scale.

?It?s going to be the natural state of things within the five years time.?

Last days of Southern Democrats? Fate of the few remaining could swing Senate control to GOP

WASHINGTON ? Republicans are counting on some Southern comfort to win Senate control next year.

The fate of Democratic incumbents in GOP-trending Arkansas, Louisiana and North Carolina, the ability of the 71-year-old GOP leader to hold his Kentucky seat and the eventual outcome of a Georgia primary will help decide whether Republicans gain the six seats necessary to grab power in the Senate for the final two years of Barack Obama's presidency.

Fifteen months before Election Day, the GOP has a genuine shot at the majority, especially with the midterm elections' traditional low turnout and possible Obama fatigue on the party's side. But both Republicans and Democrats stop short of writing off several Democratic incumbents who would have to lose for the GOP to regain power, and some Republicans worry about holding GOP seats in Kentucky and Georgia.

The transformation of the South from solidly Democratic to nearly all Republican in the half century since the 1964 Civil Rights Act has made the states generally inhospitable to Democratic politicians. And next year's elections will test whether the last remaining Southern Democrats can survive.

Overall numbers and geography favor the GOP ? 21 Democratic seats are on state ballots compared with 14 Republican. Seven of the Democratic seats are in states that Obama lost in 2012 to Republican Mitt Romney, some by 15 points or more. Adding to the GOP bullishness: Democratic retirements in three of the seven states ? West Virginia, Montana and South Dakota ? and a few recruiting disappointments.

"There's a lot of hard work to be done, but we feel very comfortable about the progression of the 2014 map in our favor and the quality of Republican candidates expressing an interest in running in key states," said Sen. Jerry Moran, R-Kan., chairman of the National Republican Senatorial Committee.

Still, Republicans had a similar edge in 2010 and 2012, and failed to take control because of flawed candidates and ill-conceived remarks. The GOP list of lost opportunities is long ? Delaware, Colorado, Nevada in 2010, Missouri, Indiana, North Dakota and Montana in 2012.

"All of those prognostications were wrong," Guy Cecil, executive director of the Democratic Senatorial Campaign Committee, said. "One of the things that we demonstrated in the last election is that Senate races are about the two people who are on the ballot."

Next year's Senate contests stand as perhaps the best chance for the GOP, especially since Republicans will have to defend 24 Senate seats to the Democrats' 10 in the presidential election year of 2016.

Currently, Democrats hold a 54-46 edge. Newark Mayor Cory Booker is expected to win next week's Democratic primary in New Jersey and the Oct. 16 special election, boosting the Democratic margin to 10.

Day 2 set in hearing on alleged Sandusky cover-up

HARRISBURG, Pa. (AP) ? Lawyers will regroup for a second day of testimony in a hearing for three former Penn State officials ensnared in the Jerry Sandusky child sex-abuse scandal, a day after a star witness testified that legendary head coach Joe Paterno had been critical of how the university handled it.

Tuesday's hearing in a Harrisburg courtroom is expected to be short, with just two witnesses.

The judge, William Wenner, must decide whether prosecutors showed enough evidence against the ex-school officials to test the charges in a full trial. The charges, including perjury, conspiracy and endangering the welfare of children, stem from allegations that former Penn State president Graham Spanier, retired university vice president Gary Schultz and ex-athletic director Tim Curley failed to tell police about an allegation against Sandusky, a former assistant football coach, and then tried to hide what they knew.

In Monday's hearing, the star witness, Mike McQueary testified in a courtroom for the third time since Sandusky's November 2011 arrest that top school officials knew that he had seen Sandusky molesting a boy in a locker room shower.

But the former Penn State assistant coach and quarterback also delivered some unexpected testimony ? that the late Hall of Fame coach Paterno had told him over the years that university administrators "screwed up" in how they responded to McQueary's allegation against Sandusky.

Pressed by defense lawyers about his discussions of the subject, McQueary brought up a specific exchange at football practice in the hours before Paterno's firing on Nov. 9, 2011 ? four days after Sandusky's arrest.

He recalled the head coach saying the school would come down hard on McQueary and try to make him a scapegoat. Paterno also advised McQueary not to trust the administration or then-university counsel Cynthia Baldwin, the former assistant testified.

Make sure to get your own lawyer, he said Paterno told him.

Lawyers for Spanier, Schultz and Curley say the men are innocent. Paterno died in January 2012. He has never been charged.

The core of McQueary's testimony is that he saw Sandusky and a boy engaged in a sex act in the locker room shower in 2001 and within days reported it to Paterno, Curley and Schultz.

However, Curley and Schultz have said McQueary never reported that the encounter was sexual in nature, while Spanier has said Curley and Schultz never told him about any sort of sex abuse. They said they believed that Sandusky and the boy were engaged in nothing more than horseplay.

Sandusky is serving a 30- to 60-year prison sentence after being convicted last year of sexually abusing 10 boys. He maintains his innocence.

Much of the testimony Monday revolved around prosecutors trying to show that Penn State officials should have known to report Sandusky to police in 2001 after police investigated complaints in 1998 that he had been showering with boys in university locker rooms.

Lawyers for the defendants tried to show they never tried to hide evidence, destroyed evidence or asked school employees to lie.

McQueary last year sued the university, claiming defamation and misrepresentation and seeking millions of dollars in damages. His contract with the school wasn't renewed after the 2011 season.

Rice University researchers create sub-10-nanometer graphene nanoribbon patterns

HOUSTON (July 30, 2013) New research at Rice University shows how water makes it practical to form long graphene nanoribbons less than 10 nanometers wide.

And it's unlikely that many of the other labs currently trying to harness the potential of graphene, a single-atom sheet of carbon, for microelectronics would have come up with the technique the Rice researchers found while they were looking for something else.

The discovery by lead author Vera Abramova and co-author Alexander Slesarev, both graduate students in the lab of Rice chemist James Tour, appears online this month in the American Chemical Society journal ACS Nano.

A bit of water adsorbed from the atmosphere was found to act as a mask in a process that begins with the creation of patterns via lithography and ends with very long, very thin graphene nanoribbons. The ribbons form wherever water gathers at the wedge between the raised pattern and the graphene surface.

The water formation is called a meniscus; it is created when the surface tension of a liquid causes it to curve. In the Rice process, the meniscus mask protects a tiny ribbon of graphene from being etched away when the pattern is removed.

Tour said any method to form long wires only a few nanometers wide should catch the interest of microelectronics manufacturers as they approach the limits of their ability to miniaturize circuitry. "They can never take advantage of the smallest nanoscale devices if they can't address them with a nanoscale wire," he said. "Right now, manufacturers can make small features, or make big features and put them where they want them. But to have both has been difficult. To be able to pattern a line this thin right where you want it is a big deal because it permits you to take advantage of the smallness in size of nanoscale devices."

Tour said water's tendency to adhere to surfaces is often annoying, but in this case it's essential to the process. "There are big machines that are used in electronics research that are often heated to hundreds of degrees under ultrahigh vacuum to drive off all the water that adheres to the inside surfaces," he said. "Otherwise there's always going to be a layer of water. In our experiments, water accumulates at the edge of the structure and protects the graphene from the reactive ion etching (RIE). So in our case, that residual water is the key to success.

"Nobody's ever thought of this before, and it's nothing we thought of," Tour said. "This was fortuitous."

Abramova and Slesarev had set out to fabricate nanoribbons by inverting a method developed by another Rice lab to make narrow gaps in materials. The original method utilized the ability of some metals to form a native oxide layer that expands and shields material just on the edge of the metal mask. The new method worked, but not as expected.

"We first suspected there was some kind of shadowing," Abramova said. But other metals that didn't expand as much, if at all, showed no difference, nor did varying the depth of the pattern. "I was basically looking for anything that would change something."

It took two years to develop and test the meniscus theory, during which the researchers also confirmed its potential to create sub-10-nanometer wires from other kinds of materials, including platinum. They also constructed field-effect transistors to check the electronic properties of graphene nanoribbons.

To be sure that water does indeed account for the ribbons, they tried eliminating its effect by first drying the patterns by heating them under vacuum, and then by displacing the water with acetone to eliminate the meniscus. In both cases, no graphene nanoribbons were created.

The researchers are working to better control the nanoribbons' width, and they hope to refine the nanoribbons' edges, which help dictate their electronic properties.

"With this study, we figured out you don't need expensive tools to get these narrow features," Tour said. "You can use the standard tools a fab line already has to make features that are smaller than 10 nanometers."
