Now you can ask Amazon's Echo about your Fitbit stats

Source: http://www.engadget.com/2016/03/17/now-you-can-ask-amazons-echo-about-your-fitbit-stats/

It was only a matter of time until someone integrated a fitness gadget with Amazon's Echo -- we should have guessed that Fitbit would be first. Starting today, you'll be able to ask any of Amazon's speakers about your Fitbit performance with a new Alexa skill. Once enabled, you can say "Alexa, ask Fitbit how I'm doing today" for a basic overview of your activity. But even more intriguing, you can ask Alexa things like how you've slept, or how much activity you've tracked, for any of the previous seven days.

Sure, it's pretty easy just to glance down at your Fitbit device, but the ability to ask about even more complex stats makes this a pretty compelling Alexa skill. Amazon's virtual assistant will even take the role of a coach with encouraging and inspirational comments, all of which will take the time of the day into account. Asking about your step count in the morning, for example, might get Alexa to say "you've got to start somewhere."

"As we look at how this integration could evolve in the future, there is an endless world of possibilities from fitness coaching and nutrition tips, to guidance before bedtime to help you get a more restful night's sleep," Tim Roberts, executive vice president of interactive at Fitbit, said in a statement.

I haven't had a chance to try out Fitbit's Alexa skill yet, but on paper it seems like the perfect use of Echo's voice smarts. It's much easier to ask about something like the amount of calories you burned yesterday and get a quick reply, rather than open your phone, find the Fitbit app, and drill down to the appropriate screen. It's even more useful than the voice-powered food and activity logging that Fitbit brought to Microsoft's Cortana last year.

How a startup is making it easy to build virtual reality worlds

Source: http://www.engadget.com/2016/03/16/voxelus-virtual-reality-gdc-2016/

My most recent virtual reality experience was created by a 9-year-old. That's according to Martin Repetto, CEO of Voxelus, a platform that lets you build, share and play your own VR games. As I roam through this Minecraft-like world, steered by a Gear VR headset, Repetto tells me that a kid is the one who designed what I'm seeing. But for Voxelus, which launched last year at the Oculus Connect 2 conference, there's a clear goal: to let anyone, young or old, make VR games without a single line of code.

At GDC 2016, Voxelus is expanding on that idea by offering a marketplace, something that Repetto refers to as the missing piece in his company's ecosystem. As it stands, Voxelus' free software is available for Mac and PC, giving people an open canvas to design games for virtual reality. These are compatible with both Gear VR and the Oculus Rift, meaning you don't have to worry about making different versions for each system.

You can also keep polishing your games even after you've made them available on either platform, and creating a world is easy as dragging and dropping items into a sandbox. Naturally, given the aesthetics of the platform, I asked Repetto if Voxelus was inspired by Minecraft, to which he replied with a strong "no." That said, Repetto notes there's a lot to learn from Microsoft's open-world title, adding that his team's intentions are to "have a sandbox with a meaning." He says, "Minecraft controls the aesthetics, [with] Voxelus you can go above and beyond."

According to Repetto, 400 worlds have been created to date using Voxelus, featuring multiplayer elements and 3D worlds like the few pictured above. Given that its software is free, Voxelus had to find a way to bring in revenue, and that's where the newly announced marketplace comes in. To simplify this process, the startup also created its own cryptocurrency, which developers are able to use to purchase any of the 7,000 VR assets available so far, including bridges, castles, houses, trees, spaceships, teleporters and more.

Repetto describes Voxelus as Clash of Clans for VR, but he says the platform, and the games born out of it, aren't meant to compete with the AAAs of the industry. "[We] just want to make something for people to play and have fun," he says.

Scientists model a Coronavirus' infectious bits for the first time

Source: http://www.engadget.com/2016/02/28/scientists-model-a-coronavirus-infectious-bits-for-the-first-ti/

A collaboration of scientists from University of Washington (UW), the Pasteur Institute and the University of Utrecht have harnessed a state-of-the-art microscope and supercomputer to model a coronavirus' infection mechanism for the first time.

Coronaviruses are really good at infecting the respiratory systems of humans and other mammals. Once inside, these viruses can cause pneumonia (if you're lucky). The strains that become SARS and MERS have a mortality rate as high as 37 percent. Plus, there is currently no antigen for SARS or MERS, which makes them especially dangerous.

The virus is so effective because of its "transmembrane spike glycoprotein," which binds to the surfaces of other cells, allowing the virus to enter. This structure is what gives coronaviruses their spiky, crown-like shape and determines what species of animals the virus can target.

The research team leveraged a single particle cryo-electron microscopy technique to model the spike of a coronavirus that infects mice in terrific detail. The team managed a 4 angstrom resolution -- about a tenth of a nanometer.

With this new analysis, the team believes they've identified a potential weaknesses in the virus' defenses. Turns out, the spike has a small peptide chain running along it. That peptide helps facilitate the virus' entry into a cell but could easily be hijacked by a treatment.

"Small molecules or protein scaffolds might eventually be designed to bind to this site," UW assistant professor of chemistry, David Veesler said in a statement, "to hinder insertion of the fusion peptide into the host cell membrane and to prevent it from undergoing changes conducive to fusion with the host cell. We hope that this might be the case, but much more work needs to be done to see if it is possible."

Google bets that smart software will improve health care

Source: http://www.engadget.com/2016/02/25/google-deepmind-health/

Google's DeepMind project has mostly focused on solving high-minded computer intelligence issues. Today, though, it's tackling something far more practical in the short-term: health care. The new DeepMind Health initiative relies on smart mobile apps to deliver medical data to doctors and nurses in time to save lives. The first app, Streams, helps spot acute kidney injuries that would otherwise go unnoticed. There are also plans to integrate technology from a third-party task management app, Hark, to identify patients that are at risk of deteriorating quickly.

The initial DeepMind Health effort is focused on the UK's National Health Service. And despite the name, it doesn't currently use artificial intelligence -- Google is "excited" about the possibility of using AI, but it's not part of these early tests. If everything pans out, though, this could go a long way toward streamlining health info and eliminating the need for archaic tech like fax machines and pagers to make sense of a patient's status.

Cheap smartphones will soon get much better graphics

Source: http://www.engadget.com/2016/02/22/imagination-power-vr-for-budget-phones/

The company that created the iPhone's graphics chip wants to bring its pixel-crunching expertise to dirt-cheap smartphones. Imagination Technologies is launching the PowerVR 8XE, a new series of chips that offer vastly better graphics for far less cash. The hardware's designed to support the new Vulkan API that promises graphically-intensive mobile games without the usual jerkiness or slowdowns. Imagination's pitch is that rather than just building ever-bigger slices of silicon, it's learning to do a lot more with a lot less. In addition to dirt-cheap smartphones, the chips will be used in cheapie set-top boxes and cars.

A more efficient graphics chip is also a smaller one, and smaller chips are often cheaper to manufacture and install. That means Imagination can offer chips with higher resolution and performance for the same price as the current generation. Given that there's so little difference between so many low-end smartphones these days, being able to offer better graphics is a big deal. It's also expected that the VR8XE chip will sip, rather than guzzle, at the smartphone's power reserves. Joe Chen, Co-CEO at MediaTek is pretty excited about the technology, saying that he's "delighted" to be one of the first firms that'll get access to the goodies.
