A Chemical Catalyst May Salvage Precious RNA From Human Tissue Samples

By thinking about how a medical preservative chemically reacts with DNA and RNA, scientists have come up with a new strategy for undoing damage to genetic material in human tissue samples. The idea, published today in the journal Nature Chemistry, might help doctors diagnose cancer or advance research on diseases like cancer more generally.

Sony unveils Xperia C5 Ultra and Xperia M5 mid-range smartphones

Sony has announced two new mid-range devices called the Xperia C5 Ultra and M5, both of which focus on camera more than anything. And they’re definitely interesting devices, both featuring 13MP front facing cameras for the ultimate selfies. If your selfie game is strong enough, you might want to buy one of these.

The Xperia C5 Ultra features dual 13MP cameras, one on the front and one on the back. This means your selfies will be as fresh as your landscape photos. The front facing camera even has a selfie flash. It also features a 6-inch 1080p IPS display, a 1.7GHz octa-core processor, 2GB of RAM, a 2.930 mAh battery, and 4G connectivity. It’s a pretty decent phone. It will also have a microSD slot and and the option for dual SIM.

The Xperia M5 one ups the C5 Ultra by including a 21.5MP rear camera in addition to the 13MP front facing camera. That rear camera has what Sony calls “5x Clear Image Zoom,” which allegedly offers zoom without loss in quality. It features a 5-inch full HD IPS display, a 2GHz octa-core MediaTek Helio X10 processor, 3GB of RAM, and a 2,600 mAh battery. And as the C5 Ultra, it will also come in single SIM and dual SIM variations, both with a microSD slot.

The two devices will be launching mid-August in select markets, though we don’t know if the US will be getting them. What are your thoughts on the selfie focus of these devices? Leave a comment!

G-Project G-TUBE review

I’ll admit it. I’m a bit of a Bluetooth speaker snob by now. My rave review of the $250 Grain Audio Bluetooth speaker should explain to you how much I value sound quality. But that doesn’t mean I can’t enjoy cheap Bluetooth speakers, provided they sound good. The G-Tube costs a measly $40 and doesn’t sound anything like you’d expect.

Overview

Price: $40.00
Battery: 6 hours
Connectivity: Bluetooth 2.1, 3.5mm aux
Extras: IPX5 splash proof, headphone out
Dimensions: 1.9″ x 1.9″ x 5.2″ (WDH)
What’s in the box: Speaker, 3.5mm aux cable, micro USB charging cable, lanyard
Where to buy: G-Project

The front houses two 1.25-inch drivers behind the black metal grille. The center and edges are rubberized for added grip and to keep the speaker standing upright. Actually, the speakers are angled up slightly, which is a nice touch.

G-Project G-TUBE 2

The left side has all the buttons, which unlike the speakers, aren’t angled (also a nice touch). There’s a play button, a Bluetooth button for easy pairing, volume up and down buttons, and a power button with G-Project’s classic three LEDs inside.

G-Project G-TUBE 3

The right side has a clip on it. But see that hinge there?

G-Project G-TUBE 4

Grab that clip and start unscrewing it. This allows the panel to come off, revealing three ports. There is a micro-USB port for charging, an aux jack, and a line out jack (more on that later).

Build quality

The build quality of this speaker is fantastic. No creaks, no flex, no cheap materials. The rubber feels good, the speaker grilles are metal, and the buttons feel high-quality.

The metal screw going through the cover on the right side struck me as an incredibly high-quality touch. Most speakers double or even triple the price use floppy rubber covers to keep water out, while this uses such an awesome system. I love it.

I do have a gripe about the center piece of rubber, though: it spins if you really try to spin it. I’m not sure if that’s intentional or not.

Sound quality

It’s a small, $40 speaker. What can you expect? A lot, apparently. This thing gets shockingly loud, easily filling a room with loud, clear audio. How they got such a small speaker to get this loud is beyond me, but it truly is impressive.

At full volume, there is a bit of distortion. It’s a rugged speaker, so some distortion at full volume for outdoor use is perfectly fine. A few clicks of the volume button and you still get really loud sound, but with perfect clarity.

The bass is also surprisingly strong. You won’t be feeling it, but it produces a nice low-end. The only issue is that the mids aren’t as strong as I’d like them to be. It’s not a perfectly balanced sound, but it’s amazing for $40.

Battery life

A 6 hour battery life rating really isn’t all that great these days. It’s about average. But at this price tag and with such a light weight, it’s fitting and is plenty of time between charges. The G-TUBE definitely gets 6 hours per charge, or even more if you listen at a quieter volume, and it charges pretty quick with a micro-USB cable.

Extras

One of the main features of this little speaker is the IPX5 splash-proof rating. This means it can withstand splashes from any direction, making it shower safe. You won’t be able to submerge it or float it in a pool, but it’ll survive minor run-ins with water.

Another cool feature is the line-out port. Since this speaker is made to take a beating, it may be used in places a smartphone shouldn’t be exposed to. The line out jack allows you to plug your headphones into the speaker, turning them into Bluetooth wireless headphones. You can hike with this little speaker clipped to your backpack strap and your earphones plugged in without your phone ever leaving the safety of your backpack. That’s ot something I’d use, but it’s still cool!

G-Project G-TUBE10 / 10

G-Project G-TUBE 5

This little speaker has a low price tag and very impressive audio. Not only does it sound good, it gets super loud. It’s also lightweight, portable, rugged, splash-proof, and very well-built. It does it all while looking quite good.

Honestly, at $40, you have to have it. I’m sure you’ll find a great use for it.

Yahoo Adds Daily Fantasy Soccer; Signs Revenue Sharing Deal

The daily fantasy sports industry received a resounding amount of attention when Yahoo launched its own daily fantasy platform in July.  Right now, Yahoo offers a daily fantasy baseball competition, but will add American football, basketball and hockey offerings when the major professional sports leagues resume play.  However, the most exciting news for Yahoo may have nary a focus on the 50 U.S. states.  It comes in the form of a partnership that will allow Yahoo to quickly expand its reach in the world of soccer and get a leg up on competitor DraftKings, which also seems to be positioning itself for expansion abroad.
