Tissue Nanotransfection (TNT): New device can heal with a single touch, and even repair brain injuries

https://www.usatoday.com/story/news/nation-now/2017/08/07/miracle-device-can-heal-single-touch-and-even-repair-brain-injuries/537326001/

New device can heal with a single touch, and even repair brain injuries

And, it not only works on skin cells, it can restore any type of tissue, Chandan Sen, director of the Center for Regenerative Medicine and Cell-Based Therapies, said. For example, the technology restored brain function in a mouse who suffered a stroke by growing brain cells on its skin.  
This is a breakthrough technology, because it's the first time cells have been reprogrammed in a live body. Current cell therapy methods are high risk, like those that introduce a virus, and include multiple steps, a new study published in Nature Nanotechnology points out. There are no known side effects to TNT and treatment is less than a second, Sen said.
“This technology does not require a laboratory or hospital and can actually be executed in the field," Sen said. "It’s less than 100 grams to carry and will have a long shelf life.” 
It is awaiting FDA approval, but Sen, who has been working on this for four years, expects TNT will be tested on humans within the year. He says he's talking with Walter Reed National Medical Center now. 
"We are proposing the use of skin as an agricultural land where you can essentially grow any cell of interest," Sen said.

animal translation in 10 years

From slashdot:
Devices that can talk to our pet dogs and cats could be less than 10 years away, according to a report Amazon commissioned that was co-authored by futurist William Higham. "Innovative products that succeed are based around genuine and major consumer needs," Higham wrote, noting the tremendous amounts already spent on our pets, and concluding, "Somebody is going to put this together." Amazon already sells one dubious device that converts human voices into meows using samples from 25 cats, according to the Guardian. (One reviewer who tested the device wrote that "the cat seems puzzled.") But Amazon's report also cites the work of Con Slobodchikoff, a professor emeritus in Northern Arizona University's biology department, who spent 30 years studying the behavior of prairie dogs. Slobodchikoff discovered prairie dogs have different words for colors and for species of predators, and is now already raising money to develop a translation device for pets.

I've been noticing this around Atlanta - black kids wearing a punk meets high fashion combo, and t-shirts with 80s and 90s era metal bands. The article mentions anime as an influence.

 “When I first met all these kids, these kids looked 10 percent punk,” said Jimmy Duval, one of the scene’s key producers. “As the sound got bigger, their image got bigger with the sound.”

PC build equivalent to X Box One X

http://www.pcworld.com/article/3200767/gaming/xbox-one-x-pc-build.html



Xbox One X PC Build: Can you do it for $500?

Creating the PC equivalent of the $500 Xbox One X is trickier than you might guess.

Updated June 16, 2017: We've revised our “upgraded” build to address our original motherboard’s incompatibility with 4K UHD HDR Blu-Ray playback.
Microsoft’s Xbox One X presents an interesting challenge for PC builders. Sure, if you want raw power, nothing beats the PC. But can you put together an Xbox One X equivalent for $500?
At that price point (and outside of that golden window of Black Friday sales and stellar combo/bundle deals on PC components), you're pushing the limits of what’s possible, particularly if you want to completely replicate the same experience Microsoft is promising hardcore console fans. Given today’s high RAM prices, the low availability of certain GPUs, and the dearth of 4K UHD drives, the results don’t come out cleanly in favor of a DIY PC.

Build #1: A basic 4K/30-fps gaming PC

To start, we’ll walk through a baseline build, which makes a few sacrifices but should still perform at 4K/30 fps.

Build breakdown

When comparing our build to the Xbox One X piece by piece, each platform’s advantages are clear. Our PC has more flexibility and muscle, while the Xbox One X is both highly compact and set in stone.
For the Xbox One X’s CPU, GPU, and memory, Microsoft chose a custom AMD APU that features eight 2.3GHz custom x86 cores, 40 Radeon compute units running at 1,172MHz, and 12GB of GDDR5 memory. AMD doesn’t have an equivalent APU available for DIY build purposes, so I chose to walk the line between the Xbox One X’s specs and recommended specs for a smooth PC gaming experience. In our build is the eight-core 3.3GHz AMD FX-8300, 8GB of DDR3/1600 RAM, and an 8GB Radeon RX 580. (My GPU choice does have one catch, which I’ve noted in the Build Summary below.)

This configuration nets you a (faster) eight-core CPU, enough RAM to avoid bottlenecks in system performance, and a GPU capable of 4K gaming at a minimum of 30 fps on Medium settings. However, some Xbox One X games may end up running more smoothly or with better visual fidelity on console than on this homebrew 4K machine. Unlike with the PC, developers can fine-tune their games for Microsoft’s console through a low-level API.
For storage, Microsoft hasn’t yet shared details on drive speed, type, or interface. All we currently know is what Digital Foundry revealed in its April 2017 preview: The Xbox One X will have a “1TB hard drive with a 50 percent increase in bandwidth.”




Without knowing how Microsoft arrived at that 50 percent figure, we could spend a lot of time speculating on what it means. (Do they mean a shift from SATA II/3Gbps to SATA III/6Gbps? Use of a solid-state hybrid drive? A larger cache?) Instead, I chose to keep this exercise simple and selected a SATA III 7200rpm Western Digital hard disk drive. While it’s possible that the Xbox One X's $500 price tag includes a SSHD, like in its now-discontinued Xbox One Elite model, that raises the price of this build without explicit cause.

The final pieces of this build are straightforward. In fact, you can use any reputable 500W power supply (the minimum you’ll need for this build), ATX case, and Blu-Ray drive—the ones listed in our build were chosen for how cheap they were at the time of publication.
Speaking of that Blu-Ray drive, it’s a far step down from the Xbox One X’s 4K UHD Blu-Ray drive. To stay even remotely near a final total of $500, you have to ditch support for playback of 4K UHD discs. So that means you can’t play your collection of 4K UHD movies in HDR on a compatible TV, if you already own one.
As for the operating system, we can’t go as cheap as the Xbox One X’s included variant of Windows 10, but we can get a W10 Home license at a heavy discount. How? By using a trick that Brad Chacos has mentioned to our staff for a while now: Buying a product key through Kinguin. It works, but be sure to get the Buyer Protection—the site functions like an eBay for software, and that insurance will protect you from shady sellers.

Build summary

As mentioned above, we wanted to replicate both the functionality and the price of the Xbox One X as closely as possible. You can’t do an exact 1:1 duplicate, thanks to a mix of Microsoft’s custom hardware design and slow release of specs, but this build is a fairly decent compromise between Xbox One X’s main features and the cost of PC components. This rig should play games in 4K at a minimum of 30 fps on a Medium graphics setting, support HDR, and play optical discs.
However, it’s more expensive than an Xbox One X by $152 (or more, if you’re bad about filing mail-in rebates). It lacks support for 4K UHD Blu-Ray discs. It uses a GPU that’s extremely difficult to find right now, so currently you’d have to pay more for a used RX 580 or buy a graphics card with less memory (Nvidia’s 6GB GTX 1060 instead of a 8GB Radeon RX 580). It doesn’t have built-in Wi-Fi support. And it’s not nearly as compact or small.

Build #2: The upgraded 4K/30-fps gaming PC

Our second build swaps out the standard Blu-Ray drive for a 4K UHD Blu-Ray drive—and changes the CPU and motherboard configuration as well.

Build breakdown

For the most part, this build shares the same approach as our first one. The key difference is the addition of Pioneer’s 4K UHD Blu-Ray drive to closely match what the Xbox One X has.
That 4K UHD Blu-Ray drive makes this build quite a bit more expensive than an Xbox One X. The BDR-211UBK itself is $130, and its highly restrictive system requirements also require a more expensive CPU and motherboard. The cheapest compatible processor is a $187 Kaby Lake Core i5-7400, and since only a few motherboards support the draconian DRM specifications for 4K UHD Blu-ray disc playback, the lowest-cost option is $149.

For the moment, you can’t get around this painful jump in cost. Pioneer has the only options for a 4K UHD Blu-Ray drive currently—and this one we’ve picked is the cheaper of the two.

Build summary

This upgraded rig nails the Xbox One X’s main features: It should run games in 4K at a minimum of 30 fps on a Medium graphics setting, support HDR, and play 4K UHD optical discs.
However, like the first build in this article, it has its downsides. First of all, if you build this PC at this very moment, you’ll have a rough time finding an RX 580. You’ll end up paying more or purchasing a GTX 1060 (which has less memory) instead.
It’s also much more expensive than the Xbox One X. At $944, you could buy the Xbox One X almost twice over.

Final thoughts

For the moment, Microsoft’s created a machine that the DIY PC crowd can’t currently match—not when you try to copy both its feature set and cost at the same time, at least. The 4K UHD Blu-Ray disc drive really throws a wrench into this build challenge, and even without it, the Xbox One X holds its own. This situation might be a first, given how often PC gamers tout benefits that console fans miss out on.

Still, it’s not a complete victory for the Xbox One X. PC gaming doesn’t require an optical drive, after all, so you can enjoy 4K gaming, 4K video content, and HDR through digital downloads. (The RX 580 will handle all that just fine.) That already drops the cost of the cheaper build we priced out.
Beyond that, these builds could change the closer we get to the Xbox One X’s launch date. When AMD’s Ryzen 3 line launches, it might offer even better CPU performance for the same price as the FX-8300. Prices might come down for RAM and Pioneer’s 4K UHD Blu-Ray drive. Availability for the RX 580 may increase again. And of course, the holiday shopping season should yield some sweet deals on at least some of these build components. By November 7th, the Xbox One X may be far easier to reproduce as a punchy $500 PC.
