Source: http://gizmodo.com/hsts-the-security-that-all-websites-should-be-using-1559701771

You would think that by now the Internet would have grown up enough that things like online banking, email, or government websites would rely on thoroughly engineered security to make sure your data isn't intercepted by attackers. Unfortunately when it comes to the vast majority of websites on the Internet, that assumption would be dead wrong. That's because most websites (with a few notable exceptions) don't yet support a standard called HSTS—HTTPS Strict Transport Security.

drag2share: Surprise: Tobacco could eventually lead to new cancer treatment

source: http://www.engadget.com/2014/04/05/tobacco-cancer-treatment/?utm_source=Feed_Classic_Full&utm_medium=feed&utm_campaign=Engadget&?ncid=rss_full

When tobacco and cancer are used in the same sentence, the word "cause" usually goes in between. That's why a new research from La Trobe University in Australia could confuse some folks -- after all, the researchers discovered that tobacco could potentially be used for cancer treatment. Before you pick up that box of Marlboros, know that it's actually a flowering tobacco plant named Nicotiana alata, which isn't even the same species used to make cigarettes, that has magical, cancer-beating properties. After a series of tests, the scientists have determined that NaD1 (a protein found in its pink and white flowers) can not only fight off plant fungi, but also kill cancer cells.

Apparently, NaD1 latches onto cancer cells with its pincer-like structure, causing them to form little balloons on the surface until they explode. But, what makes it an ideal cure is that while it attacks affected cells, it leaves healthy ones untouched. According to lead researcher Dr. Mark Hulett from the school's Molecular Science program, a huge issue with the therapies we use today is that unlike the NaD1 protein, they attack cells indiscriminately.

Of course, the irony of it all didn't escape his notice. He said:

There is some irony in the fact that a powerful defence mechanism against cancer is found in the flower of a species of ornamental tobacco plant, but this is a welcome discovery, whatever the origin.

Like any new medical discovery, though, the protein has to go through years of more rigorous testing and research. In fact, Hulett believes we have to wait at least 10 more years before it's ready to step out of the lab and into the hospital.

drag2share: Sony announces full-frame Alpha A7s with 4K video output

Source: http://www.engadget.com/2014/04/06/sony-alpha-a7s/

It wouldn't be NAB without a major 4K announcement from Sony, and that's exactly what we've got here. The company introduced the Alpha A7s at its Las Vegas press event today, bringing 4K video to the popular full-frame mirrorless camera line. The "s" in the new camera's name stands for sensitivity, and to that end it supports an ISO range of 50 to 409,600. The 12.2-megapixel full-frame sensor limits downscaling with 3,840 x 2,160 (QFHD) 4K video, ultimately resulting in higher quality footage. While you can store 1080p video internally, you'll need to use an external recorder to capture 4K video, which the camera outputs with 4:2:2 color sampling via HDMI.

You can store XAVC S-format video with a class 10 or higher SDXC card. When in 1080p mode, you can also opt to shoot with APS-C cropping, while 120 fps capture is supported when you jump down to 720p. The A7s can snap still images, of course, but it really shines when it comes to capturing 4K and HD video. The camera supports S-Log2 gamma, expanding the dynamic range to 1300 percent, resulting in reduced shadow and highlight clipping.

Physically, the A7s looks identical to its Alpha siblings, with a solid design and feel. It also sports WiFi and NFC, for wireless transfers to a smartphone or tablet. Also, like the other Alpha 7 cams, the A7s includes a Multi Interface Shoe, so you can add in Sony's XLR mic adapter kit, the XLR-K1M. Pricing has not yet been announced, but Sony executives say to expect the camera in stores this summer, just a few months after Panasonic's GH4. Check it out in our video below.

drag2share: DJI improves stabilization, tilt and flying speed with Phantom 2 Vision+ drone

Source: http://www.engadget.com/2014/04/06/dji-phantom-2-vision-plus/

It was just this January that we tested DJI's Phantom 2 Vision drone, a $1,199 quadcopter with an integrated 14-megapixel/1080p camera and tilt-axis gimbal. Now at NAB, DJI's back with a "plus" version of its airborne craft. The refreshed gadget, which retails for $100 more than its predecessor, includes a new three-axis gimbal (compared to single-axis stabilization) for smoother captures, more than double the WiFi communication distance (700 meters, or about 3,000 feet), a 50-percent boost in maximum flight speed (to 15 meters or 50 feet per second) and a 90-degree tilt that lets you shoot subjects directly below.

There's also an integrated GPS system that enables you to set an autonomous path or keep the Phantom in the same spot in winds of up to 25 miles per hour, while the DJI Vision app lets you preview footage and access altitude, distance and battery strength during shoots. Finally, DJI is releasing a firmware update for all Phantom drones that lets pilots avoid flying near airports or user-generated no-fly zones. Availability remains TBA, but expect to drop $1,299 for your Phantom 2 Vision+ once it's ready to ship.

drag2share: DJI brings its smooth video tech to the ground with Ronin camera gimbal

Source: http://www.engadget.com/2014/04/06/dji-ronin-gimbal/

DJI's best known for its versatile photography drones, but the company's bringing its stabilization technology to ground-based shoots with the Ronin camera gimbal. The compact device, which appears to be a more consumer-friendly version of last year's Movi Freefly, is designed to work with a variety of compact cameras, from DSLRs to a Red Epic. The handheld gimbal is based on the firm's ZenMuse tech, which you'll find in select camera copters. A single videographer can control the rig, or you can have a second operator manage pan and tilt wirelessly. Ronin can be configured in less than five minutes using a companion smartphone app, which enables auto calibration after balancing the camera. Pricing should come in under $5,000, and DJI says to expect the device to ship later this quarter.
