Pandora Premium ad-free streaming service kicks off at $10 per month

Why it matters to you

Pandora Premium is Pandora’s answer to Spotify, Apple Music, and others, and it’s not a bad start.

Pandora, the 17-year-old streaming music service best known for its ad-supported free radio stations, is launching a paid tier aimed at the likes of Spotify, Apple Music, Tidal, SoundCloud, and Google Play Music. It’s called Pandora Premium, and it offers on-demand and offline access to more than 40 million songs for $10 a month.

The bulk of the Pandora Premium experience takes place within a smartphone app. Unlike apps from some of Pandora’s competitors, it doesn’t feel overwrought — it’s minimalist, simple, and streamlined. There’s a carousel of recently played albums and stations, a list music saved for later listening, and filters that let users to search for specific albums, artists, and song lists. A simple toggle makes it easy to hide explicit music on radio stations and in search, and a New Music section offers tracks tailored to individual tastes.

Premium boasts a more than just music, though. An curatorial team is tasked with getting rid of karaoke, tribute songs, and duplicate tracks, which Pandora said will improve the quality of search results. Premium has millions of curated and auto-generated radio stations that offer variations on a theme — like ’80s party hits, Smooth Jazz, and Orchestral. And a “favorites” feature put songs users give a “thumbs-up” into a personalized playlist.

Pandora has made it easy to grow music collections over time. An “add similar songs” feature lets users add algorithmically related tracks to an existing playlist, and a soon-to-launch AutoPlay feature will create a station based on the song or album you just listened to.

The launch of Pandora Premium comes 15 months after Pandora acquired assets from Rdio, and shortly after the company launched a $5-a-month Pandora Plus with ad-free listening, downloads, high-quality streaming audio, and an unlimited number of skips and replays.

The competition is fierce, but Pandora thinks its recommendation features give it a leg up. Its Music Genome Project, a decade-long effort to “capture the essence of music at the most fundamental level” using over 450 attributes to describe songs, powers Premium’s song suggestions. And the company is using dozens of additional signals to offer “intelligent” and “informed” recommendations.

But Premium will have to contend with exclusives. The past year has seen Apple Music and Tidal ink timed deals with Kanye West, Drake, Frank Ocean, Chance the Rapper, and Beyoncé. The broader music industry is against the idea — Universal Music Group has banned exclusives, as have Lady Gaga, Adele, and Spotify — but that won’t change the fact that Pandora Premium subscribers will have to wait longer for some singles and albums than others.

And compared to some of the competition, Pandora Premium is fairly bare-bones. For example, it’s launching without a desktop app or an iPad app and there aren’t music videos. And while it works with Chromecast, Apple CarPlay, and Android Auto, it doesn’t support Sonos or Amazon Echo devices.

But despite all that, Pandora’s convinced that it can convert at least a few of the 80 million users who listen to Pandora each month to Premium customers. To entice existing users, it’s offering a free two-month trial for all account holders and a six-month trial for Pandora Plus subscribers.

Pandora CEO Tim Westergren said the company is aiming for 6-9 million paying customers by the end of the year. “We have very grand ambitions for what this can be” Pandora CEO Westergren told The Verge. “No one has solved the ease of use and personalization part of the on-demand world. I don’t think there’s really a true premium product out there yet … we think we’re bringing something really different here.”

With Premium, Pandora is angling to nab the more than 100 million collective people who pay for music subscriptions globally. Apple Music is paying subscribers number north of 10 million (out of 20 million), and Spotify crossed the 100-million-user threshold earlier this year.

Time will tell whether Pandora can wean users away from their music streaming service of choice, but it’s off to a strong start. According to research firm MusicWatch, Pandora earned 28 percent of all streaming music hours in 2016. YouTube (including YouTube Red subscriptions) was second at 27 percent and Spotify came in third (17 percent).

Pandora is rolling out Premium on iOS and Android, with current users first in line. It’s only available in the United States, for now, but the company has plans to roll it out to territories in Australia and New Zealand.

Apple’s ResearchKit may be a viable alternative to traditional studies

Why it matters to you

The successful use of this platform could lower the cost of medical research studies involving the collection of similar survey data.

Apple launched ResearchKit, a software medical platform that helps researchers recruit participants for studies, back in 2015. Since then, it’s been tapped by the University of Oxford, Stanford Medicine, and the Dana-Farber Cancer Institute to track trial progress, deliver surveys, and collect medical data. But it has faced questions of efficacy, and some in the medical community have challenged its accuracy.

In at least one case, though, researchers found Apple’s ResearchKit to be a viable alternative to traditional pen-and-paper studies.

In a study published in the journal Nature Biotechnology, researchers at New York City’s Mount Sinai Hospital used Apple’s ResearchKit to crowdsource data from asthma patients. Nearly 50,000 iPhone users download the asthma app, and of these, about 7,600 people enrolled in the six-month study after completing the consent form. (About 2,300 ended up being “robust users” — folks who filled out multiple surveys.)

More: GlaxoSmithKline is the first drug company to use Apple’s ResearchKit

Participants in the study took surveys on how they treated their asthma, and researchers cross-referenced their responses with data on external factors like air quality and location.

The results ended up matching fairly well. Around the time there were wildfires in Washington state, for example, patients in the area reported worse asthma symptoms. And elsewhere, researchers were able to correlate data related to heat and pollen.

But collecting data via smartphones presented other challenges ways. The study’s retention rate was relatively low — about 85 percent of participants completed one survey, and only 30 percent completed more than one over the course of six months. Because participants were required to self-report, it’s possible they submitted untruthful, misleading, or incomplete information.

There’s the potential, too, for an unrepresentative sample. As The Verge points out, Android phone owners were precluded from participating in the study because Apple’s ResearchKit platform doesn’t support third-party operating systems.

Still, the researchers concluded that ResearchKit could be useful for short-term studies.

“We […] found that this methodology is particularly suitable for studies of short duration that require rapid enrollment across diverse geographical locations, frequent data collection, and real-time feedback to participants,” Dr. Yvonne Chan, principal investigator of the study and the director of Digital Health and Personalized Medicine at the Icahn Institute for Genomics and Multiscale Biology, said in a statement. “Our study demonstrates the power of mobile health tools to scale and accelerate clinical research so that we can derive the evidence needed to inform clinical practice and improve patient care.”

That’s good news for the scientific community. At the time of the study, there were an estimated three billion smartphones in use around the world, a number that’s expected to double by 2020.

“We now have the ability to capture rich research data from thousands of individuals, to better characterize ‘real world’ patterns of disease, wellness, and behavior,” Dr. Eric Schadt, senior author on the paper, said in a statement. “This approach provides a more comprehensive and accurate view of our patients that was not feasible in the past due to logistical limitations and prohibitive costs.”

Giphy Stickers lets you send your friends some love in a GIF

Why it matters to you

GIFs are surely the best way to communicate, and now, you can do so more easily than ever with a new GIF sticker app from Giphy.

No time for a GIF? First of all, who are you? But second of all, and more importantly, there’s a solution (even if it’s not a real problem). Giphy wants to make sure that everyone everywhere is capable of enjoying the distinct joy GIFs can bring (like nothing else really can), and it’s doing it by way of new GIF stickers.

Thanks to a new app creatively named Giphy Stickers, you’ll be able to search, download, and yes, even create your very own GIF-based stickers to share with others, or just keep to yourself for a laugh on a rainy day. The app, which is available on both Android and iOS, is certainly an improvement over Imoji, a sticker app Giphy acquired with very little fanfare at the end of last year. And now, we understand just what the company has been up to since making that mysterious purchase.

Whereas previously, the Imoji app only allowed you to make and share unmoving images, the new-and-improved version a la Giphy allows you to create living stickers. You can make them turn, shake, sparkle — just about anything you want.

“Developers who want to bring sticker search to their apps will now have the easiest way to access the best content,” a Giphy spokesperson told Mashable via email. “Stickers are the ultimate quick mode of communication, and since Apple launched iOS 10, they’re now an amazing way to annotate other content.”

This isn’t the first time Giphy has expanded its offerings, especially as they relate to text messages. Earlier in March, the platform debuted Artist Sticker Packs, which were 13 sets of GIF-esque stickers made specifically for iOS 10. Oh, and Giphy is also introducing a Stickers API for developers, which means you can expect even more moving stickers in the coming weeks and months. See what’s shaking already in the Giphy Stickers channel, and get ready to GIF up your life.

We took the Mule Light V2 on an overnighter in the woods to put its illumination to the test

Like many backpackers, and those who constantly spend time in the wilderness, I’ve developed an obsession with flashlights. Even after finding what I think will be the last light, I see another that’s brighter, or lighter, or more energy efficient than the last.

Recently I came across the Mule Light V2 by UV Paqlite, a unique flashlight that touts a complete package of features and energy efficiency and uses nontoxic strontium aluminate crystals encased in a molded resin to extend illumination time.

Unlike traditional glow-in-the-dark stuff — which comes in a powder whose particles are so small the amount of light they hold and emit is minimal — the UV Paqlite’s crystals absorb more light and emit it longer. The crystals are protected from oxidization by the resin and avoid degradation via light absorption or brightness unlike other glow-in-the-dark products.

So the company claims, anyway. We hit a few trailheads overnight to find out first hand.

Trek Into darkness (under stars)

At night in the woods, it can get pretty dark. Trees overhead block out the moonlight, and as you’re hunting for a good spot to set up a tent — and poring over a map praying for your eyes to adjust — the right flashlight is key.

I began hiking a section of the Arizona Trail leading out of Pine, AZ east to the Mogollon Rim. This rim forms the southern edge of the Colorado Plateau, where views of pine forests and desert canyons provide dramatic scenery. At nearly 5,500 feet in elevation it winds through the Coconino National Forest, the largest Pondarosa Pine forest in the world. A combination of the elevation, towering vegetation and time of year, contributed to a short amount of actual daylight.

The overall design, being light weight and energy efficient, made me believe that the company really had the wilderness adventure in mind.

I found the level of illumination from the rechargeable Mule Light V2 to be impressive. During my review, I was easily able to read my trail guide book by the light from the crystals. It also maintained a consistent glow, one comparable to that of traditional glow sticks but without the inconvenience of carrying multiple sticks — saving pack space, reducing weight, and eliminating extra trash.

Built into the side of the flashlight’s non-conducting, shock-resistant casing is a two function 12 Cree LED utility light. The first, a UV black light, is useful for anyone that frequents the desert to check their boots, packs, and sleeping bags for scorpions or other potential stowaways. The second function, a 100 lumen work light, can be used to illuminate the inside of a tent, and can also be set to a delayed pulse mode which is used to recharge the detachable and reusable strontium aluminate crystals glow stick.

The Mule Light V2 has a three setting (high, low, and strobe) 300 lumen spotlight and attachable red lens filter. This bright, focused beam was strong enough to pierce the darkness of the trail on a moonless night.

Power Source Flexibility

The functionality of this light is completed by the multi-option power source choices. The light comes with two different battery packs, a 3 AAA battery adaptor and 1 USB rechargeable lithium ion battery. Either battery pack can be used to power the light, allowing for flexibility between the availability of a recharging source and the convenience of using traditional lithium batteries when your setting is more off-the-grid.

Wesley Parrell/Digital Trends

When either battery pack is used in conjunction with the flashlight’s hybrid energy saving mode, UV Paqlite boasts a combine use time of over 600 hours with these power sources. The light can also be used with alkaline batteries for 240 hours of operating time in the hybrid energy saving mode.

Warranty

UV Paqlite has a lifetime warranty covering materials and workmanship and will repair or replace it—hassle free. All other components are covered by a 90-day warranty. UV Paqlite advertises the overall case construction as a highly durable copolymer non-conducting shock resistant case which seemed durable during our testing and the resin coated strontium aluminate crystal glow stick was solid. With proper care and nonintentional abuse, this light should last for years to come.

I was impressed in how this light broke the industrial, bulky stigma of multifunction lights.

There are other light manufactures out there and definitely better specific use lights such as headlamps, tactical light, and spotlights, but I could not find one that combines all of the functions that this light possesses in one unit. The combined energy efficiency and power source options really made this light stand out especially in the multi-function light market.

There were some misses in this light’s design. The clip used to attach the light to a pack trap seemed flimsy and untrusting without also using the provided lanyard as a backup to keep the light attached to the pack. Although we liked having a red lens option, the small detachable lens would be easy to lose or misplace. A red led light option would be better.

Overall I was impressed in how this light broke the industrial, bulky stigma of multifunction lights. The design, being light weight and energy efficient, made me believe that the company really had the wilderness adventure in mind. You should buy this light if you’re looking for a way to cover multiple lighting needs and want to cut pack weight. Don’t buy this light to replace the hands free function of a headlamp for hiking.

• Energy efficient
• Multi-option power source
• Rechargeable glow stick
• Compact multifunction capability

Lows

Acton’s Blink S electric skateboard is finally here for your adventure needs

Why it matters to you

The Blink S was one of the most anticipated electric skateboards last year, and now, it’s starting to ship to its earliest supporters.

It may be a retro hobby, but this new skateboard is all new tech. Following one of the most successful Indiegogo campaigns in the crowdfunding platform’s history, electric skateboard designer and manufacturer Acton has begun shipping its Blink S board. The skateboard raised more than $1.4 million in funding last year, and now, skating enthusiasts from around the world have renewed reason to rejoice.

Promising a top speed of up to 15 mph and a battery life that will last you seven miles, the Blink claims to be the “perfect rideable for city dwellers [and] college students.” You can charge the skateboard in as little as an hour, and the hub motors promise a powerful yet smooth ride. Speaking of hub motors, the Blink will still work as a conventional skateboard even if you run out of juice, as these sorts of motors don’t slow you down in the way belted motors might.

With an aircraft aluminum extrusion and a wood deck, the Blink S is super lightweight and portable. The board also comes with a remote control that allows you to control the forward and reverse functions, and also doubles as an accelerator and brake. So really, all you need to do is keep your balance.

And of course, because this is a smart, connected board, it comes with an app that allows you to set modes, check mileage, track routes, and otherwise stay engaged in the skateboarding community. You can now order the Blink S for $699 on the Acton Online Store.

If you’re in the market for other skateboards, however, Acton has a couple more products in the pipeline. There’s the Blink S2, which features two-wheel drive, which allows for “effortless uphill power” for your hillier commutes (the Blink S has one-wheel drive). And the most powerful of the lot is the Blink Qu4tro, which offers an impressive four-wheel drive to adventurers. These two boards are expected to start shipping in the coming months, so keep your eyes peeled.

ZTE teased a March 21 event that could host a dual-camera Nubia smartphone

Why it matters to you

Dual cameras are becoming commonplace, meaning better quality photos that can be taken straight from your phone.

It looks like we could be getting a new ZTE smartphone in the near future. ZTE began teasing a March 21 event on its Weibo account, where the company is expected to unveil a new Nubia smartphone with a dual camera on the back. It’s not known exactly what device in the Nubia series the phone will end up being but if it does have a dual camera, it will mark ZTE’s first attempt at bringing that feature to its Nubia range.

How do we know that there will be a dual camera phone at the event? Well, we don’t know for sure but accompanying the teaser is a graphic that shows two circles that look suspiciously like camera lenses.

There don’t seem to be any rumors about a Nubia device with a dual camera just yet and we may just have to wait until the event to get any details about it. According to a user on Chinese social media network Weibo, however, the phone may boast a borderless display and it could be powered by the new Qualcomm Snapdragon 835. If that is true, it will only be the second smartphone with a Snapdragon 835 — coming after the Sony Xperia XZ, which was the first Snapdragon 835-powered phone.

This will mark the second Nubia phone to be released in a month — the company launched the Nubia N1 Lite at MWC at the end of last month. The phone boasts a 5.5-inch HD display with a 1,280 x 720-pixel display and a MediaTek 64-bit processor with 2GB of RAM. It also had 16GB of storage and a microSD card slot and a single-lens 8MP camera. It’s powered by a 3,000mAh battery and 4G connectivity and has a fingerprint scanner on the back of the device.

Oxford scientists are building robots that ‘wear’ artificial skin before it’s transplanted

There’s a thin line between man and machine, and it’s only getting thinner. Intelligent algorithms are starting to perceive sights and sounds like human beings. Androids are taking more anthropomorphic forms, powered by actuators wrapped silicone and latex skins. Even these skins are becoming increasingly lifelike. Earlier this year, researchers created an artificial material that’s twice as sensitive as human skin. And this month, a team of Oxford professors proposed a provocative idea — grow human tissue on humanoid robots.

“Humanoid robots have the potential to closely mimic both the structure and the movements of the patient’s body.”

Pierre-Alexis Mouthuy and Andrew Carr didn’t at first intend to delve into robotics. They’re biomedical researchers, concerned with interactions between tissue and bone. But, while studying strategies to repair tendon injuries through tissue engineering, the pair realized they’d need to test their lab-grown tissues in dynamic environments that simulate what it’d be like to be stretched, pulled, and contracted by the human body.

“The current bioreactor systems offered for that are still in their infancy and are relatively expensive,” Mouthuy told Digital Trends. “Therefore we have decided to look into designing our own bioreactor systems to solve this problem.”

In a review published this month in the journal Science Robotics, Mouthuy and Carr explore a the concept of growing human transplant tissue on “humanoid bioreactors.”

“We have always been well aware of the technological developments that are being made in robotics, and in particular in musculoskeletal humanoid research,” Mouthuy said. “Musculoskeletal humanoids, which mimic the human body’s skeletal structure, are rapidly becoming better at mimicking natural body movements. We thought that investigating whether or not these robots could support the growth of tendons and other musculoskeletal tissues was now becoming both technically possible and scientifically relevant.”

The purpose isn’t necessarily to start some sort of cyberpunk revolution

Tissue tears and, the older we get, the more fragile our bodies become. Failures in tendons, ligaments, and bones can cripple patients and cause burdens to society. But it doesn’t have to be that way. Just as researchers have created sophisticated ways to replace teeth, hair, and even limbs, scientists are working on better ways to engineer tissue grafts. In 2013, scientists at the University of Pittsburgh School of Medicine grew human heart tissue that could beat on its own. Last, year scientists from the RIKEN Center for Developmental Biology (CDB) in Japan reprogrammed cells to grow as complex skin tissue, hair follicles and all.

More: Researchers have created an artificial material that’s twice as sensitive as human skin

Current tissue engineering techniques require a controlled environment within what’s known as a bioreactor, which sustains conditions needed for cells to live outside the body and stimulates those cells to develop as desired. However, as Mouthuy and Carr point out in their review, the chemical and mechanical stimuli provided by current bioreactors don’t do enough to replicate the dynamic stresses of the body – all the stretching, pulling, and contracting that your skin experiences as your move.

In order to grow clinically relevant grafts, the researchers say future bioreactors will need to push and pull tissues in multiple directions, adapt stresses depending on where the tissue will be implanted into the body, and be able to grow tissue to scale. “In this context, humanoid musculoskeletal robots become very relevant as they have the potential to closely mimic both the structure and the movements of the patient’s body,” Mouthuy said.

The researchers point to a few humanoid robots — such as Kenshiro and Eccerbot —  for ideas of how these bioreactors may take shape.

More: Robots and AI are coming for our jobs. But can augmentation save us from automation?

The purpose of the article wasn’t necessarily to start some sort of cyberpunk revolution — although, we say, Viva la révolucion! Rather, Mouthuy said he and Carr wanted spark discussion and collaboration between roboticists and regenerative medical experts.

Moving forward, the team will need to conduct a proof of concept. “We are currently designing small bioreactor prototypes that could be used in combination with musculoskeletal robots,” Mouthuy said. “We hope to be able to test these in the near future.”

Scientists create ‘lip password’ that IDs users by their lips’ movements

Why it matters to you

The latest research into biometric authentication looks at verifying users through their lip motions.

A team of scientists have developed a new biometric authentication method that identifies someone through the motions of their lips.

The “lip motion password,” or lip password, has been designed by Professor Cheung Yiu-ming and researchers at Hong Kong Baptist University. The method involves matching the lip motion associated with saying your password to the user’s lip characteristics.

More: Study: Accuracy of voice biometrics can diminish as we age

The researchers at the university’s department of computer science claim that lip movement is unique to the individual. It cannot be easily impersonated and an impostor will be denied entry by the system, they said. “The same password spoken by two persons is different and a learning system can distinguish them,” commented Professor Cheung.

Cheung and his team developed a computational learning model that examined the visual features of a person’s lips including shape, texture, and movement.

This biometric authentication method could provide an additional layer of security for access to programs or systems. According to Cheung, it is a better system than voice activation, which can be inhibited by background noise. Further, lip passwords can be used by people with hearing or speech impairments and the method is not susceptible to language barriers, allowing anyone to use it, at least in theory.

In the future, the lip password could be integrated with facial recognition authentication systems for even more robust security and verification, the researchers said.

Biometrics using features like fingerprints have become much more common in recent years but they present a fundamental problem – they can’t be changed. If fingerprint scan data is ever stolen, the user needs to find a new method of authentication. The researchers in Hong Kong believe their new method of lip motions can provide security while allowing the user to change or reset it when they want.

The researchers have already obtained a patent for the method and expect to see it first deployed in financial transaction verification. They added that other use cases include ATM verification, mobile payments, and managing access to private premises.

See what a rocket engine’s 512K pounds of thrust looks like up close — and in 360

Why it matters to you

As if an engine that could help send a spaceship to Mars isn’t cool enough, NASA tested the engine — and recorded it with 360 cameras.

NASA’s Space Launch System (SLS) vehicle is expected to boast an unprecedented 2 million pounds of thrust to explore deeper into space — but watching just one of the four engines being tested is quite impressive by itself. Earlier this month, NASA shared a 360 video offering a glimpse at just how powerful the RS-25 engine is.

Four of the RS-25s will eventually be used to carry an unmanned Orion spaceship deeper into the solar system, including on a possible mission to Mars. The launch system is based on three decades of research. For added power, the new RS-25 uses 25 percent more fuel than the one that powered the space shuttle. The SLS is designed to launch only once, unlike a shuttle.

The test shows just how much smoke the heat of the engine creates. Multiple 360 cameras were used to record the testing from a number of different vantage points, including one camera that was placed right inside the flame trench, which helps to direct the exhaust away from the launch pad, and ends up surrounded by smoke and water. The water in the trench is even vaporized enough to make a double rainbow.

The hot fire test was conducted at the Stennis Space Center in Mississippi in February. The entire test lasted more than six minutes, but the video was trimmed to a little over two minutes.

The Space Launch System is NASA’s largest rocket to date, designed to be adaptable for both unmanned and crewed missions. The RS-25 is the engine that powered the space shuttle during 30 years of operation. It’s one of the most tested large rocket engines in history, with more than 3,000 starts and more than 1 million seconds of total ground test and light ring time. NASA is upgrading the engines for the SLS with electronic controllers and new nozzle insulation. While the SLS is expected to have two variations with different boosters, the system uses four of the RS-25 engines in both cases.
